Sulphated and unsulphated bile acids in serum, bile, and urine of patients with cholestasis. (1/2758)

Samples of serum, bile, and urine were collected simultaneously from patients with cholestasis of varying aetiology and from patients with cirrhosis; their bile acid composition was determined by gas/liquid chromatography and mass spectrometry. In cholestasis, the patterns in all three body fluids differed consistently and strikingly. In serum, cholic acid was the major bile acid and most bile acids (greater than 93%) were unsulphated, whereas, in urine, chenodeoxycholic was the major bile acid, and the majority of bile acids (greater than 60%) were sulphated. Secondary bile acids were virtually absent in bile, serum, and urine. The total amount of bile acids excreted for 24 hours correlated highly with the concentration of serum bile acids; in patients with complete obstruction, urinary excretion averaged 71-6 mg/24 h. In cirrhotic patients, serum bile acids were less raised, and chenodeoxycholic acid was the predominant acid. In healthy controls, serum bile acids were consistently richer in chenodeoxycholic acid than biliary bile acids, and no bile acids were present in urine. No unusual monohydroxy bile acids were present in patients with primary biliary cirrhosis, but, in several patients, there was a considerable amount of hyocholic acid present in the urinary bile acids. The analyses of individual bile acids in serum and urine did not appear to provide helpful information in the differential diagnosis of cholestasis. Thus, in cholestasis, conjugation of chenodeoxycholic acid with sulphate becomes a major biochemical pathway, urine becomes a major route of bile acid excretion, and abnormal bile acids are formed.  (+info)

Analysis of the effects of food and of digestive secretions on the small intestine of the rat. 1. Mucosal morphology and epithelial replacement. (2/2758)

A modified Roux-en-Y repositioning of rat small intestine was performed so that the proximal segment of bowel (A) received only bile and pancreastic secretions, the second (B) received food direct from the stomach, and these two segments drained into a third (C). Four to five weeks after operation, cell production was assessed by injection of vincristine into operated, sham-operated and unoperated rats, and counts of blocked metaphases were made on isolated microdissected crypts. Villus height, crypt depth, and the number of crypts per villus (crypt/villus ratio) were also measured. Most of segment A showed no significant differences from sham-operated intestine, although the normal proximo-distal gradient of villus height was abolished. At the distal end (near the anastomosis with segments B and C), crypt depth and cell production were increased. The villus height gradient in segment B was also abolished, although crypt depth and cell production were significantly increased, especially at the proximal end. Crypt/villus ratio was also increased. Segment C showed all the characteristics of small bowel promoted to a more proximal position: increased villus height, crypt depth and cell production. Increased crypt/villus ratio was also observed. These results are discussed in terms of the role of food and of digestive secretions in the control of mucosal morphology and epithelial replacement.  (+info)

Progesterone alters biliary flow dynamics. (3/2758)

OBJECTIVE: To test the hypothesis that progesterone alters sphincter of Oddi and gallbladder function and, therefore, bile flow dynamics. SUMMARY BACKGROUND DATA: Although the effects of progesterone on the biliary tract have been implicated in the increased incidence of gallstones among women, the specific effects of prolonged elevation of progesterone levels, such as occurs with contraceptive progesterone implants and during pregnancy, on the sphincter of Oddi and biliary flow dynamics are still incompletely understood. METHODS: Adult female prairie dogs were randomly assigned to receive subcutaneous implants containing either progesterone or inactive pellet matrix only. Hepatic bile partitioning and gallbladder emptying were determined 14 days later using 99mTc-Mebrofenin cholescintigraphy. RESULTS: Significantly less hepatic bile partitioned into the gallbladder in progesterone-treated than in control animals. The gallbladder ejection fraction was significantly reduced from 73+/-6% in controls to 59+/-3% in the progesterone-treated animals. The rate of gallbladder emptying was significantly reduced from 3.6+/-0.3%/minute to 2.9+/-0.1%/minute. CONCLUSIONS: Progesterone administered as subcutaneous implants alters partitioning of hepatic bile between gallbladder and small intestine and, therefore, gallbladder filling. Progesterone also significantly impairs gallbladder emptying in response to cholecystokinin. The effects of progesterone on the sphincter of Oddi and the gallbladder may contribute to the greater prevalence of gallstones and biliary motility disorders among women.  (+info)

A new bile acid conjugate, ciliatocholic acid, from bovine gall bladder bile. (4/2758)

This study was carried out to investigate the occurrence of ciliatocholic acid in bovine gall bladder bile. Ciliatocholic acid was synthesized according to the method described by Bergstrom and Norman for the synthesis of taurocholic acid. Elemental analysis, melting point, and the infrared spectrum of this substance were determined. An isolation procedure for ciliatocholic acid was established by stepwise elution with an HCl-ethanol solvent system using a Dowex-1 anion exchange resin column chromatographic technique. Ciliatocholic acid amounting to 158 mug (as ciliatine) per 100 ml of gall bladder bile was found in the fraction eluted with 0.01 N HCl in 50% ethanol. This coumpound was purified by preparative thin-layer chromatography and confirmed to be ciliatocholic acid from the hydrolytic stability, phosphorus determination, and chromatographic behavior. Thus, bovine gall bladder bile contains a small amount of ciliatocholic acid.  (+info)

An interpretation of the serum alkaline phosphatase isoenzyme patterns in patients with obstructive liver disease. (5/2758)

Earlier studies have identified two main isoenzymes of alkaline phosphatase in the sera of patients with obstructive liver disease. This paper reports on a study of these isoenzymes in specific types of liver disease where the pathology in relation to bile duct obstruction is known. The results have been used to support the theory that in biliary obstruction the increase in serum alkaline phosphatase is in part due to regurgitation of the biliary isoenzymes.  (+info)

Influence of renal failure on intestinal clearance of ciprofloxacin in rats. (6/2758)

Following intravenous doses, ciprofloxacin pharmacokinetics in control and nephrectomized rats were studied. There were no differences between control and nephrectomized rats for area under the concentration-time curve in plasma or biliary clearance. The intestinal clearance of ciprofloxacin was increased in nephrectomized rats. Intestinal elimination seems to compensate partially for the decrease in urinary excretion of ciprofloxacin in nephrectomized rats.  (+info)

Cryoelectron microscopy of a nucleating model bile in vitreous ice: formation of primordial vesicles. (7/2758)

Because gallstones form so frequently in human bile, pathophysiologically relevant supersaturated model biles are commonly employed to study cholesterol crystal formation. We used cryo-transmission electron microscopy, complemented by polarizing light microscopy, to investigate early stages of cholesterol nucleation in model bile. In the system studied, the proposed microscopic sequence involves the evolution of small unilamellar to multilamellar vesicles to lamellar liquid crystals and finally to cholesterol crystals. Small aliquots of a concentrated (total lipid concentration = 29.2 g/dl) model bile containing 8.5% cholesterol, 22.9% egg yolk lecithin, and 68.6% taurocholate (all mole %) were vitrified at 2 min to 20 days after fourfold dilution to induce supersaturation. Mixed micelles together with a category of vesicles denoted primordial, small unilamellar vesicles of two distinct morphologies (sphere/ellipsoid and cylinder/arachoid), large unilamellar vesicles, multilamellar vesicles, and cholesterol monohydrate crystals were imaged. No evidence of aggregation/fusion of small unilamellar vesicles to form multilamellar vesicles was detected. Low numbers of multilamellar vesicles were present, some of which were sufficiently large to be identified as liquid crystals by polarizing light microscopy. Dimensions, surface areas, and volumes of spherical/ellipsoidal and cylindrical/arachoidal vesicles were quantified. Early stages in the separation of vesicles from micelles, referred to as primordial vesicles, were imaged 23-31 min after dilution. Observed structures such as enlarged micelles in primordial vesicle interiors, segments of bilayer, and faceted edges at primordial vesicle peripheries are probably early stages of small unilamellar vesicle assembly. A decrease in the mean surface area of spherical/ellipsoidal vesicles was correlated with the increased production of cholesterol crystals at 10-20 days after supersaturation by dilution, supporting the role of small unilamellar vesicles as key players in cholesterol nucleation and as cholesterol donors to crystals. This is the first visualization of an intermediate structure that has been temporally linked to the development of small unilamellar vesicles in the separation of vesicles from micelles in a model bile and suggests a time-resolved system for further investigation.  (+info)

Environmental signals modulate ToxT-dependent virulence factor expression in Vibrio cholerae. (8/2758)

The regulatory protein ToxT directly activates the transcription of virulence factors in Vibrio cholerae, including cholera toxin (CT) and the toxin-coregulated pilus (TCP). Specific environmental signals stimulate virulence factor expression by inducing the transcription of toxT. We demonstrate that transcriptional activation by the ToxT protein is also modulated by environmental signals. ToxT expressed from an inducible promoter activated high-level expression of CT and TCP in V. cholerae at 30 degrees C, but expression of CT and TCP was significantly decreased or abolished by the addition of 0.4% bile to the medium and/or an increase of the temperature to 37 degrees C. Also, expression of six ToxT-dependent TnphoA fusions was modulated by temperature and bile. Measurement of ToxT-dependent transcription of genes encoding CT and TCP by ctxAp- and tcpAp-luciferase fusions confirmed that negative regulation by 37 degrees C or bile occurs at the transcriptional level in V. cholerae. Interestingly, ToxT-dependent transcription of these same promoters in Salmonella typhimurium was relatively insensitive to regulation by temperature or bile. These data are consistent with ToxT transcriptional activity being modulated by environmental signals in V. cholerae and demonstrate an additional level of complexity governing the expression of virulence factors in this pathogen. We propose that negative regulation of ToxT-dependent transcription by environmental signals prevents the incorrect temporal and spatial expression of virulence factors during cholera pathogenesis.  (+info)

The effect of a new potent choleretic drug (Febuprol) on lipid composition and cholesterol nucleation time in gallbladder bile was studied in 8 patients with cholesterol gallstones. Nine untreated patients with cholesterol cholecystolithiasis and functioning gallbladder served as controls. Under Febuprol treatment (3 X 100 mg for 6-10 days) mean concentrations of total bile acids (125.4 vs. 59.5 mmol/l), phospholipids (46.1 vs. 25.6 mmol/l) and total lipids (10.4 vs. 5.9 g/dl) were significantly higher (p less than 0.01) than in controls. No significant difference between both groups was calculated for the mean values of cholesterol (17.8 vs. 13.3 mmol/l), cholesterol saturation index (1.5 vs. 2.1) and cholesterol nucleation time (2.1 vs. 2.6 days). Our findings are compatible with a choleretic effect of Febuprol but no alteration of the rapid cholesterol crystallisation in gallbladder bile of patients with cholesterol gallstones was found. ...
Epomediol (1,3,3-trimethyl-2-oxabicyclo(2.2.2.)octan-6,7-endo,endo-diol) (EPO) is a terpenoid compound shown to reverse 17 alpha-ethinylestradiol (EE)-induced cholestasis in rat. The effect is related to the restoration of normal liver plasma membrane fluidity values. To further characterize the effect of EPO, bile flow and biliary lipid composition were measured in rats treated either with EE or EE associated with EPO. EE significantly reduced the bile flow; this reduction was prevented by concomitant treatment with EPO with an increase in the bile salt secretion rate. EPO alone showed a choleretic effect. The biliary secretion rate of cholesterol was also significantly reduced by EE while being comparable to controls in EE-EPO-treated animals. Phospholipid (PL) biliary excretion was significantly (P less than 0.002) increased by EE either alone or combined with EPO. After EE treatment, the biliary PL composition showed a reduction in phosphatidylcholine (PC) concentration with a parallel ...
2H2O affects many membrane transport processes by solvent and kinetic isotope effects. Since bile formation is a process of osmotic filtration where such effects could be important, we investigated the effects of 2H2O on bile formation in the in situ perfused rat liver. Dose finding experiments showed that at high concentrations, 2H2O increased vascular resistance and induced cholestasis; at 60% 2H2O however, a clear dissociation between the vascular and biliary effects was observed. Therefore, further experiments were carried out at this concentration. The main finding was a reduction in bile salt-independent bile flow from 0.99 +/- 0.04 to 0.66 +/- 0.04 microliters.min-1.g-1 (P , 0.001). This was associated with a 40% reduction in biliary bicarbonate concentration (P , 0.001). Choleretic response to neither taurocholate nor ursodeoxycholate was altered by 2H2O; in particular, there was a similar stimulation of bicarbonate secretion by ursodeoxycholate in the presence of 60% 2H2O. To further ...
Bile or gall is a dark green to yellowish brown fluid, produced by the liver of most vertebrates, that aids the digestion of lipids in the small intestine. In humans, bile is produced continuously by the liver (liver bile), and stored and concentrated in the gallbladder (gallbladder bile). After eating, this stored bile is discharged into the duodenum. The composition of gallbladder bile is 97% water, 0.7% bile salts, 0.2% bilirubin, 0.51% fats (cholesterol, fatty acids and lecithin), and 200 meq/l inorganic salts. Bile was the yellow bile in the four humor system of medicine, the standard of medical practice in Europe from 500 B.C. to the early nineteenth century. About 400 to 800 ml of bile is produced per day in adult humans. Bile acts to some extent as a surfactant, helping to emulsify the lipids in food. Bile salt anions are hydrophilic on one side and hydrophobic on the other side; consequently, they tend to aggregate around droplets of lipids (triglycerides and phospholipids) to form ...

N2 - Pancreaticobiliary maljunction (PBM) is a congenital anomaly in which the reciprocal reflux between pancreatic and bile juice occurs because the conflu- ence of the pancreatic and bile ducts lies outside of the area of contractile influence of the sphincter of Oddi. The reflux of pancreatic juice into the bile duct and subse- quent elevated pancreatic enzyme level in bile are usually recognized in PBM. Amylase is the most popular pancreatic enzyme for assessment in daily prac- tice, and assessment of amylase level in bile is useful to definitively confirm the presence of PBM, and the mixture of pancreatic and bile juices may produce various physiological and pathological alterations. In PBM, the amylase level in bile in patients with biliary cancers has been reported to be higher than that with benign biliary diseases; however, ...
Bile is secreted by the hepatocytes and its water and electrolyte composition altered during its passage down the biliary system. Between meals much of the bile is diverted to the gallbladder where it is concentrated by the removal of sodium, chloride, bicarbonate, and water. In response to food, the gallbladder contracts, emptying bile into the duodenum. Apart from water (97%) the major components of bile are bile acids, phospholipids, and cholesterol. Bile is also the major excretory route of other compounds including bilirubin and certain drugs and their metabolites. Cholesterol is insoluble in water but is held in solution by the detergent action of bile acids with the aid of phospholipids.. Cholesterol is synthesized primarily in the liver and small intestine. The rate-limiting enzyme for cholesterol production is hydroxymethylglutaryl-CoA reductase (EC 1.1.1.34), which catalyses the first step, the conversion of acetate to mevalonate. Subsequently, nonesterified (free) cholesterol is ...

Lets review. The liver is a large organ that produces bile. Bile plays a role in the breakdown of fats and, more specifically, is defined as a yellowish-green fluid that aids in the emulsification of fats. When a large fat droplet is emulsified, it is essentially broken down into smaller droplets.. Bile enters the duodenum when dietary fats are present. If any bile remains after the fat has been digested, it is taken back up by the gallbladder. The gallbladder is a small sac-shaped organ that stores and concentrates bile.. The common bile duct is a common duct that carries bile from the liver and the gallbladder to the duodenum. If this duct is blocked, it can cause the yellowish-colored bile to back up and enter the bloodstream. This can lead to a yellowing of the skin and the whites of the eyes, known as jaundice.Hormones play a role in the release of digestive secretions.. For example, secretin is a hormone produced in the walls of the small intestine that stimulates the liver to produce ...

This study compares the biliary and urinary metabolic profiles of 1,2-diethyl-3-hydroxypyridin-4-one (CP94), an orally active iron chelator, in the normal rat. Surprisingly, CP94 was found to form two phase II metabolites, the 3-O- and 4-O-glucuronides. These glucuronides accounted for 38 and 28% of the administered CP94 dose, in bile and urine, respectively. Unchanged CP94 accounted for 5% of the CP94 dose in both bile and urine. The 2-(1′-hydroxy) metabolite of CP94 was found to be the dominant metabolite in urine. In addition, an unstable metabolite was detected in the bile although its structure remains unknown at the present stage. The excretion of iron in bile, after administration of CP94, was found to parallel the biliary elimination of CP94 together with its hydroxylated derivatives, indicating the importance of metabolites in iron excretion.. ...

Horses do not have a gall bladder. This means they have no where to store the bile that is produced by the liver. This bile is what helps break down and digest food in the intestines. In humans, dogs, goats and sheep, this bile is released by the gall bladder as needed. This is not the case for horses. So what happens when there is no place to store this bile? It is constantly released into the small intestine, regardless of whether there is food to digest or not. If your horse has gone a prolonged amount of time without eating, they may start to look a bit jaundiced (yellowish in the whites of eyes and gums) from the build-up of bile in the bloodstream ...

TY - JOUR. T1 - Modulation of the stimulatory effect of pregnenolone-16α-carbonitrile on biliary cholesterol output in the rat by manipulation of the rate of hepatic cholesterol synthesis. AU - Turley, Stephen D.. AU - Dietschy, John M.. PY - 1984/8. Y1 - 1984/8. N2 - In female rats fed a plain ground diet containing pregnenolone-16α-carbonitrile, biliary cholesterol output increased twofold, whereas bile acid and phospholipid output either remained unchanged or decreased slightly. There was a 32% increase in liver weight, a 3.5-fold increase in cholesteryl esters, and a 45% decrease in the rate of hepatic sterol synthesis. When pregnenolone-16α-carbonitrile was fed with AOMA, an agent that blocks cholesterol absorption, there was less of an increase in cholesteryl esters, the inhibitory effect of pregnenolone-16α-carbonitrile on hepatic sterol synthesis was abolished, and biliary cholesterol output was increased to an even greater extent. In contrast, when pregnenolone-16α-carbonitrile was ...
Irinotecan, 7-ethyl-10-[4-(1-piperidino)-1-piperidino]-carbonyloxycamptothecin (CPT-11), is a potent anticancer drug that is increasingly used in chemotherapy. A frequent limiting side effect involves gastrointestinal toxicity (diarrhea), which is thought to be related to the biliary excretion of CPT-11 and its metabolites. Accordingly, the biliary excretion mechanisms for both the lactone and carboxylate forms of CPT-11 and its metabolites, SN-38 and its glucuronide (SN38-Glu), were investigated using Sprague-Dawley (SD) rats and Eisai hyperbilirubinemic rats (EHBR), with the latter being mutant rats with a genetic deficiency of the canalicular multispecific organic anion transporter. After i.v. administration of CPT-11, the biliary excretion clearance, defined as the biliary excretion rate normalized to the hepatic concentration, of both the lactone and carboxylate forms of SN38-Glu was much lower in EHBR. The biliary excretion clearance for the carboxylate form of both CPT-11 and SN-38 was ...
Dec 22, 2005. SAN DIEGO, CA - Dec 22, 2005 - Diazyme Laboratories, a company that applies its proprietary enzyme technologies to develop low cost and high quality diagnostic products for clinical and research uses, announced today that the U.S. Food and Drug Administration (FDA) has granted Diazyme 510(K) clearance to market its Enzymatic Total Bile Acids (TBA) Assay Kit for the quantitative determination of total bile acids in human blood samples.. Total bile acids is a well known bio-marker for diagnosis of liver diseases. Serum total bile acids are elevated in patients with acute hepatitis, chronic hepatitis, liver sclerosis, and liver cancer. Total bile acids levels are found to be the most sensitive indicator for monitoring the effectiveness of interferon treatment of chronic hepatitis C patients. Moreover, total bile acids tests are also widely used to screen pregnant women for the condition of obstetric cholestasis, a disease that is caused by elevated total bile acids in the bloodstream ...
Since the last International Bile Acid Meeting in Freiburg in 1996, considerable progress has been made in several areas of bile acid research. The different pathways of bile acid synthesis and their regulation have been further characterized. The molecular mechanisms for biliary secretion of bile acids have been elucidated and genetic defects of bile acid transport have been defined. Injurious as well as protective effects of different bile acids on the liver have been further studied. Finally, the beneficial effects of ursodeoxycholic acid in cholestatic liver diseases have been substantiated and the potential mechanisms of action have been explored. This book, the proceedings of the Falk Symposium No. 108 (XV International Bile Acid Meeting), held in Titisee, Germany, October 12-13, 1998, is dedicated to both basic and clinical aspects of bile acid research with a focus on bile acids and cholestasis.Bile Acids and Cholestasis - XV International Bile Acid Meeting, 1 was published 1999 under ...
For the past year we have employed a mixture of oleic acid and bile salts for the treatment of patients suffering from various forms of gall-bladder disease. The results obtained, which were reported elsewhere15 were gratifying in a large number of cases. We then decided to undertake an experimental study of the choleretic effect of bile salts and of oleic acid with bile salts to ascertain whether oleic acid which has a direct action on the gall-bladder also enhances the well known choleretic effect of bile salts. Theoretically, as will be shown later, it appeared plausible that such would be ...
Purpose. Biliary organic anion excretion is mediated by an ATP-dependent primary active transporter, a so-called canalicular multispecific organic anion transporter (cMOAT). As there appear to be many canalicular organic anion transports, we examined the effects of various organic anions and bile acid conjugates on the biliary excretion of pravastatin in rats. Methods. [l4C]pravastatin was intravenously injected into rats with bile drainage in the presence and absence of the continuous infusion of organic anions and bile acids, and radioactivity of its biliary excretion was studied. Results. Biliary excretion of [14C]pravastatin was markedly inhibited by sulfobromophthalein-glutathione, taurolithocholate-3-sulfate, ursodeoxycholate-3,7-sulfate, and ursodeoxycholate-3-O-glucuronide. In contrast, dibromosulfophthalein only slightly inhibited biliary pravastatin excretion, and cefpiramide did not affect biliary pravastatin excretion. Conclusions. These findings further support the multiplicity of

The presence of a renal bile fistula with escape of all bile into the urinary tract seriously impairs the capacity of an anemic dog to form new hemoglobin on standard diets. These bile fistula dogs will produce about one-half as much hemoglobin in anemia on standard diets as during earlier control periods without a bile fistula. Iron given by mouth to an anemic bile fistula dog will effect the production of about one-half the amount of new hemoglobin as in control periods. Iron given by vein to an anemic bile fistula dog will approximate the theoretical 100 per cent return of new hemoglobin. Obviously absorption is a very important factor in the utilization of iron by these dogs. The reaction to liver feeding is much like the reaction to iron feeding but we have no proof of inadequate protein digestion and absorption in these bile fistula dogs. In fact the uniform body weight and normal clinical state over periods of years speak for adequate absorption of protein digestion products. Evidence ...
Bile acids are steroidal amphipathic molecules derived from the catabolism of cholesterol. They modulate bile flow and lipid secretion, are essential for the absorption of dietary fats and vitamins, and have been implicated in the regulation of all the key enzymes involved in cholesterol homeostasis. Bile acids recirculate through the liver, bile ducts, small intestine and portal vein to form an enterohepatic circuit. They exist as anions at physiological pH and, consequently, require a carrier for transport across the membranes of the enterohepatic tissues. Individual bile acid carriers have now been cloned from several species. Na(+)-dependent transporters that mediate uptake into hepatocytes and reabsorption from the intestine and biliary epithelium and an ATP-dependent transporter that pumps bile acids into bile comprise the classes of transporter that are specific for bile acids. In addition, at least four human and five rat genes that code for Na(+)-independent organic anion carriers with ...
50% cholesterol monohydrate plus an admixture of calcium salts, bile pigments, and proteins. Pigment stones are composed primarily of calcium bilirubinate; -There are several important mechanisms in the formation of lithogenic (stone-forming) bile. The most important is increased biliary secretion of cholesterol. This may occur in association with obesity, the metabolic syndrome, high-caloric and cholesterol-rich diets. cholesterol gallstone disease occurs because of several defects, which include:- (1) bile supersaturation with cholesterol, (2) nucleation of cholesterol monohydrate with subsequent crystal retention and stone growth, and (3) abnormal gallbladder motor function with delayed emptying and stasis.

To study the effect of steroid hormones on bile acid synthesis by cultured rat hepatocytes, cells were incubated with various amounts of these compounds during 72 h and conversion of [4-14C]cholesterol into bile acids was measured. Bile acid synthesis was stimulated in a dose-dependent way by glucocorticoids, but not by sex steroid hormones, pregnenolone or the mineralocorticoid aldosterone in concentrations up to 10 microM. Dexamethasone proved to be the most efficacious inducer, giving 3-fold and 7-fold increases in bile acid synthesis during the second and third 24 h incubation periods respectively, at a concentration of 50 nM. Mass production of bile acids as measured by g.l.c. during the second day of culture (28-52 h) was 2.2-fold enhanced by 1 microM-dexamethasone. No change in the ratio of bile acids produced was observed during this period in the presence of dexamethasone. Conversion of [4-14C]7 alpha-hydroxycholesterol, an intermediate of the bile acid pathway, to bile acids was not ...
1. Coeliac patients are known to have an expanded bile salt pool which recirculates slowly due, at least in part, to impaired gall bladder contractility. We have investigated the possibility that delayed small bowel transit of chyme and bile may also contribute to this sluggish recycling.. 2. Plasma cholylglycine, total bile acids and cholecystokinin concentrations were measured after a lactulose-labelled test meal whose mouth-caecum transit time (M-C TT) was assessed by the breath hydrogen technique.. 3. Overall there were no significant differences in plasma bile acid profiles between seven healthy controls and a group of 25 coeliac patients. However, when subjects were divided according to their M-C TT, the 10 with the slowest transit were found to have significant elevation of fasting levels when compared with the 10 with the fastest transit, fasting total bile acids being 3.4 ± 1.3 versus 0.7 ± 0.6 μmol/l (P , 0.02) and fasting cholylglycine being 0.43 ± 0.17 versus 0.06 ± 0.04 μmol/l ...
Bile acids are usually found conjugated to glycine or taurine, a derivative of cysteine. Cells require the presence of an active bile acid transporter for uptake of these conjugated derivatives (10). To test whether conjugated bile acids would also activate FXR, we coexpressed the human ileal bile acid transporter (IBAT) with FXR in CV-1 cells (11). FXR was strongly activated by 3 μM of the taurine or glycine conjugates of CDCA, LCA, and DCA (Fig. 2G). Weaker activation was seen with the conjugated forms of CA, and tauro-MCA was inactive (Fig. 2G). These data indicate that FXR can be activated by conjugated bile acids in tissues that express bile acid transporters such as the terminal ileum, liver, and kidney. The relation between the chemical structure of bile acids and their activation of FXR is in close agreement with the reported effects of bile acids on induction of I-BABP expression in Caco-2 cells and inhibition of Cyp7a expression in hepatocytes (3, 12). Coactivator proteins interact ...
We investigated whether bile salts (BS) with different hydrophobic-hydrophilic properties interact with ethanol on bile secretion, enzyme (aspartate transaminase [AST], lactate dehydrogenase [LDH]) release in the perfusate, liver ultrastructure, and vesicular exocytosis in the isolated perfused rat liver. Ethanol (0.1 or 1%) promoted a rapid decrease of bile flow and BS secretion in livers perfused with taurocholate (TCA), the physiologic BS in the rat (−28% decrease of baseline values with 0.1% and −34% with 1% ethanol). The inhibitory effect of ethanol on bile flow and BS secretion was significantly (P , .02) attenuated by perfusing liver with the hydrophilic BS, tauroursodeoxycholate (TUDCA), and it was exacerbated (P , .02) by perfusion with the hydrophobic BS, taurodeoxycholate (TDCA). The release of AST and LDH in the perfusate was unaffected by 0.1% ethanol, but increased threefold to fivefold by 1% ethanol in TCA-perfused livers. This cytolitic effect of ethanol was not observed in ...
This morning Kay went to the interventional radiology suite at Good Sam, and John, the self described candy man who administers the drugs for conscious sedation, and Dr. Frood were able to safely drain Kays obstructed biliary system. There was a very high grade obstruction of the common bile duct, allowing very little bile to drain into the intestine. One advantage of being thin is that he was able to access the bile ducts through the left lobe of the liver, through the abdominal wall beside her prior surgical incision. This avoids the need to go from the right side between the ribs, the usual approach, and avoids the pain of this tube moving with each breath causing a lot of pain. They drained a large amount of bile, and were able to pass a small drainage tube down through the bile ducts into the duodenum. The tube has small holes above the blockage, and in the tube into the duodenum, so bile can drain into the gut. What bile does not drain that direction, can drain out into a small bag ...
The classical functions of bile acids include acting as detergents to facilitate the digestion and absorption of nutrients in the gut. In addition, bile acids also act as signaling molecules to regulate glucose homeostasis, lipid metabolism and energy expenditure. The signaling potential of bile acids in compartments such as the systemic circulation is regulated in part by an efficient enterohepatic circulation that functions to conserve and channel the pool of bile acids within the intestinal and hepatobiliary compartments. Changes in hepatobiliary and intestinal bile acid transport can alter the composition, size, and distribution of the bile acid pool. These alterations in turn can have significant effects on bile acid signaling and their downstream metabolic targets. This review discusses recent advances in our understanding of the inter-relationship between the enterohepatic cycling of bile acids and the metabolic consequences of signaling via bile acid-activated receptors, such as ...

In addition to their well-known function as dietary lipid detergents, bile acids have emerged as important signalling molecules that regulate energy homeostasis. Recent studies have highlighted that disrupted bile acid metabolism is associated with metabolism disorders such as dyslipidaemia, intestinal chronic inflammatory diseases and obesity. In particular, type 2 diabetes (T2D) is associated with quantitative and qualitative modifications in bile acid metabolism. Bile acids bind and modulate the activity of transmembrane and nuclear receptors (NR). Among these receptors, the G-protein-coupled bile acid receptor 1 (TGR5) and the NR farnesoid X receptor (FXR) are implicated in the regulation of bile acid, lipid, glucose and energy homeostasis. The role of these receptors in the intestine... in energy metabolism regulation has been recently highlighted. More precisely, recent studies have shown that FXR is important for glucose homeostasis in particular in metabolic disorders such as T2D and ...

Bile reflux. Endoscope view of bile (yellow, lower centre) in the stomach. Bile reflux is a condition that occurs when bile flows upward (refluxes) from the small intestine into the stomach and oesophagus. Bile, a digestive juice made in the liver, aids the digestion of lipids in the duodenum (first part of the small intestine). Symptoms include nausea, heartburn and vomiting bile. Unlike acid reflux, it usually cannot be completely controlled by changes in diet or lifestyle. Instead, it is most often managed with medication or, in severe cases, with surgery. - Stock Image C001/2842

Bile is the green liquid that is made by the liver and is essential for digesting fat. Without some fat in the diet we would not be able to survive as it is essential for the absorption of fat soluble vitamins, so bile is therefore essential for health. Bile is made by the cells of the liver and is collected within a series of tubes within the liver itself called the bile ducts. These run down into one main tube called the common bile duct which delivers the bile into the gut (duodenum) where it is mixed with the food. Off the common bile duct is a side branch and at the end of the side branch is the gallbladder. Under normal circumstances bile passes straight down the common bile duct into the gut but during fasting, typically, some of the bile is bypassed down the side branch where it is stored within the gallbladder. So in effect the gallbladder acts as a storage organ for the bile and when food is taken in the gallbladder contracts and any bile that is stored within it is forced out down the ...
A group from the University Hospital in Heidelberg, Germany performed quantitative polymerase chain reaction for herpesvirus 1-8 DNA in bile, blood, and liver tissue of 73 patients after first liver transplantation (LT). They determined that CMV, EBV, HHV-6, and HHV-7 were all more prevalent in biliary fluid than in liver biopsy tissue or serum. HHV-6 was detected in 34.2% of bile samples while in only 15.1% of biopsy and 2.4% of serum samples. Currently, serum is most often used to test for possible HHV-6 reactivation in transplant patients, but the German study suggests that bile fluid could serve as a more effective marker. The group also found that HHV-6 positivity in bile was significantly associated with allograft complications (including graft rejection and death) but serum positivity was not. This association was found only for HHV-6 and held true even when DNA copies levels were relatively low.. All the patients in this study were treated with prophylactic valganciclovir to prevent CMV ...
The biliary excretion of the major methadone metabolites was studied after the administration of purified 14C-labeled metabolites of methadone. The three methadone metabolites administered to rats were the pyrrolidine and pyrroline metabolites and the glucuronide conjugate of the hydroxylated pyrroline metabolite. We found that the excretion of 14C into bile was greater after administration of the metabolites which underwent fewer metabolic steps prior to biliary excretion. Phenobarbital pretreatment of rats increased the biliary excretion of 14C after the administration of the 14C-labeled pyrrolidine and pyrroline metabolites, both of which undergo further metabolism. Phenobarbital pretreatment did not change the biliary excretion of 14C-labeled glucuronide of the pyrroline metabolite which does not undergo further metabolism in the liver. Analysis of bile samples showed that the increased biliary excretion of 14C in phenobarbital-pretreated rats after administration of the labeled pyrrolidine ...
The key components of bile are; bile salts that facilitate enzymatic fat digestion; bile pigments, such as bilirubin, that are the waste product of hemoglobin
The primary bile acids (BAs) are synthetized from colesterol in the liver, conjugated to glycine or taurine to increase their solubility, secreted into bile, concentrated in the gallbladder during fasting, and expelled in the intestine in response to dietary fat, as well as bio-transformed in the colon to the secondary BAs by the gut microbiota, reabsorbed in the ileum and colon back to the liver, and minimally lost in the feces. BAs in the intestine not only regulate the digestion and absorption of cholesterol, triglycerides, and fat-soluble vitamins, but also play a key role as signaling molecules in modulating epithelial cell proliferation, gene expression, and lipid and glucose metabolism by activating farnesoid X receptor (FXR) and G-protein-coupled bile acid receptor-1 (GPBAR-1, also known as TGR5) in the liver, intestine, muscle and brown adipose tissue ...

Bile acids are water-soluble and, when ionized, amphipathic end products of cholesterol metabolism formed in the liver.? In their molecular form, they are weak acids, however, after the biosynthesis process, the bile acid molecules are conjugated with glycine and taurine, converting them into strong amino acids before being excreted from the hepatocyte.. The fundamental role of bile acids is to aid in the digestion and absorption of fats and fat-soluble vitamins in the small intestine. ...

Pancreas and bile in the human body can be figuratively in good or in very bad relationship.They can be the friends in healthy situation, but can be worst enemy causing diseases of each other.. They have much similarity: without both pancreatic juice and bile we cannot digest the food, especially fat.. Bile and pancreatic juice both have a big amount of minerals and bicarbonates and in normal condition are alkaline.. Both bile and pancreatic juice go to the duodenum (beginning of small intestine) using special pathways: bile and pancreatic ducts. They merge each other before entering the duodenum and mix of pancreatic juice and bile enter in the duodenum throughout special valve called sphincter Oddi.. Negative changing of the biochemistry of bile or pancreatic juice, structure of ducts, possible back ups of these fluids can lead to diseases, some of them fatal.. There are simple examples. Pancreatic cancer causes severe damage of liver because the tumor squeezes the bile duct, developing back ...
There are two different ways to connect the bile duct to the intestine, depending on the liver disease of the patient. The first way is connecting the patients own bile duct to the donor bile duct. If this is done, a small tube called a T-tube, is placed between the bile duct connections. The tube will then exit through the skin but is easily concealed by clothing. This allows the team to monitor the amount and consistency of bile being made by the liver. This tube is tied off within the first week and removed six months after transplantation. The second way to connect the bile duct to the intestine is used if a patients own bile duct is diseased. In this situation, the new bile duct will be connected with the patients intestine. A small tube called a stent, is placed at the connection site. It later falls out of the duct on its own and is passed in the stool sometime after the operation ...
Bile - What causes green bile? Chemical properties. Biliverdin is a green tetrapyrrolic bile pigment, and is a product of heme/redcell breadown. Biliverdin is further broken down to bilirubin for easier excretion to the outside world (also into urobilinogen in urine-as mild yellow). This compound absorbs green light, thus appears green to your eyes! (put in dard room=brown/black). I think u maybe asking why u threw up green? Consult doc. Good luck.

Ox Bile (enteric coated): Bile is a substance made in the liver, stored in the gallbladder, and secreted into the intestines to break down fats. It also carries toxins, foreign chemicals, and hormones out of the body. Bile is composed of lecithin, salts, and cholesterol, and gallstones can form when these ingredients are out of balance. When bile cannot be properly delivered from the liver and gallbladder to the intestines, diarrhea, constipation, indigestion, cramping, bloating, pain, and other abdominal distress can occur. Low levels of bile can also lead to deficiencies in Vitamins A, D, E, and K, which depend on the absorption of fat and which impact a number of other health issues. Gallstone blockage and poor contractility from a sick and weak gallbladder are common reasons for poor delivery of bile to the intestines. In addition to assisting digestions, ox bile can protect the gut from infection, reduce the occurrence of gallstones, improve the systemic balance of cholesterol, and reduce ...

Primary biliarycirrhosis (PBC) is a progressive disease of the liver caused by a buildup of bile within the liver (cholestasis) that results in damage to the small bile ducts that drain bile from the liver. Over time, this pressure build-up destroys the bile ducts leading to liver cell damage. As the disease progresses and enough liver cells die, cirrhosis and liver failure occur.. Bile is manufactured in the liver and then transported through the bile ducts to the gallbladder and intestine where it helps digest fats and fat soluble vitamins (A,D,E,K). When bile cannot be drained from the liver, it causes inflammation that leads to cell death. Scar tissue gradually replaces the areas of damaged liver and then the body cannot perform necessary functions.. ...
The discovery of unidirectional, ATP-dependent canalicular transport systems (also termed export pumps) for bile salts, amphiphilic anionic conjugates, lipophilic cations, and phospholipids has opened new opportunities for understanding biliary phy
Background:. Biliary obstruction and cholangitis are common problems in gastroenterology and need specific therapeutic interventions. Besides a variety of potential causes, infections of the biliary tract with Candida and other fungal species have increasingly been reported in the last few years [1-6]. Fungal infections can even lead to common bile duct (CBD) obstruction, as previously reported [7]. Because of the difficulty of gaining bile samples, little is known about the microbial flora of the bile. In a first prospective, observational study, 123 consecutive patients undergoing ERCP for various indications were screened for fungal species [8]. According to this data Candida species may be very frequently be detected in the bile (54/123 patients, 44 % of the cases). As significant risk factors immunosuppression and long-term antibiotic therapy were identified. The main issue in this context is whether positive diagnostic findings represent fungal infection or fungal colonization. Especially ...

The liver is constantly producing bile. When it isnt needed for the digestion of food, the bile enters the gallbladder to be stored. Here water is extruded concentrating the bile and making it ten to fifteen times stronger than the bile produced by the liver. Bile digests fat, it also contains waste eliminated by the liver as it breaks down drugs, hormones and proteins. Bile is released into the duodenum to aid digestion. ...
When the gallbladder is removed, special clips are used to seal the tube that connects the gallbladder to the main bile duct. However, bile fluid can occasionally leak out into the tummy (abdomen) after the gallbladder is removed.. Symptoms of a bile leak include tummy pain, feeling sick, a fever and a swollen tummy.. Sometimes this fluid can be drained off. Occasionally, an operation is required to drain the bile and wash out the inside of your tummy.. Bile leakage occurs in around 1% of cases. ...

BaP's metabolites are mutagenic and highly carcinogenic, and it is listed as a Group 1 carcinogen by the IARC. Chemical agents and related occupations, Volume 10, A review of Human Carcinogens, IARC Monographs, Lyon France 2009 [13] In June 2016, BaP was added as benzo[def]chrysene to the REACH Candidate List of Substances of very high concern for Authorisation.[14] Numerous studies since the 1970s have documented links between BaP and cancers.[15] It has been more difficult to link cancers to specific BaP sources, especially in humans, and difficult to quantify risks posed by various methods of exposure (inhalation or ingestion).[citation needed] A link between vitamin A deficiency and emphysema in smokers was described in 2005 to be due to BaP, which induces vitamin A deficiency in rats.[16] A 1996 study provided molecular evidence linking components in tobacco smoke to lung cancer.

All groups of dioxin-like compounds are persistent in the environment.[61] Very few soil microbes nor animals are able to break down effectively the PCDD/Fs with lateral chlorines (positions 2,3,7, and 8). This causes very slow elimination. However scientists at Martin Luther University recently found that a type of bacteria Dehalococcoides CBDB1 can extract the chlorine from dioxin compounds in the absence of oxygen.[62][63] Ultraviolet light is able to slowly break down these compounds. Lipophilicity (tendency to seek for fat-like environments) and very poor water solubility make these compounds move from water environment to living organisms having lipid cell structures. This is called bioaccumulation. Increase in chlorination increases both stability and lipophilicity. The compounds with the very highest chlorine numbers (e.g. octachlorodibenzo-p-dioxin) are, however, so poorly soluble that this hinders their bioaccumulation.[61] Bioaccumulation is followed by biomagnification. Lipid-soluble ...

Indigo was the foundation of centuries-old textile traditions throughout West Africa. From the Tuareg nomads of the Sahara to Cameroon, clothes dyed with indigo signified wealth. Women dyed the cloth in most areas, with the Yoruba of Nigeria and the Mandinka of Mali particularly well known for their expertise. Among the Hausa male dyers, working at communal dye pits was the basis of the wealth of the ancient city of Kano, and they can still be seen plying their trade today at the same pits.[6] In Japan, indigo became especially important in the Edo period, when it was forbidden to use silk, so the Japanese began to import and plant cotton. It was difficult to dye the cotton fiber except with indigo. Even today indigo is very much appreciated as a color for the summer Kimono Yukata, as this traditional clothing recalls Nature and the blue sea. Newton used "indigo" to describe one of the two new primary colors he added to the five he had originally named, in his revised account of the rainbow in ...

Benzene, C6H6, is the simplest aromatic hydrocarbon, and it was the first one named as such. The nature of its bonding was first recognized by August Kekulé in the 19th century. Each carbon atom in the hexagonal cycle has four electrons to share. One goes to the hydrogen atom, and one to each of the two neighbouring carbons. This leaves one electron to share with one of the two neighbouring carbon atoms, thus creating a double bond with one carbon and leaving a single bond with the other, which is why the benzene molecule is drawn with alternating single and double bonds around the hexagon. The structure is alternatively illustrated as a circle around the inside of the ring to show six electrons floating around in delocalized molecular orbitals the size of the ring itself. This depiction represents the equivalent nature of the six carbon-carbon bonds all of bond order 1.5; the equivalency is explained by resonance forms. The electrons are visualized as floating above and below the ring with the ...

... exerts its effects on the human body by downregulating expression of genes. Genes PLK1 and PIN1, both oncogenic, have been shown to be affected by indirubin. Indirubin has, in vitro and in vivo, been shown to reduce expression of the CDC25B gene, which codes for production of CDC25B enzyme. CDC stands for cell-division-cycle, and is used in cellular reproduction. Studies suggest that mouse cells are viable after the CDC25B (and CDC25C) genes are "knocked out", but removal of CDC25A results in non-viable cells. Indirubin has not been shown to prevent or treat cancer in humans.[1] However, it is being studied for treatment of small-cell lung cancer, glioblastoma,[2] and chronic myeloid leukemia, either alone or in conjunction with more typical cancer management treatments. It has also been studied for potential use in the treatment of ulcerative colitis, an immune-modulated disease process.[3] Indirubin shows anti-inflammatory and anti-angiogenesis properties in vitro.[4] ...
