Cytochrome P-450 Enzyme System
A superfamily of hundreds of closely related HEMEPROTEINS found throughout the phylogenetic spectrum, from animals, plants, fungi, to bacteria. They include numerous complex monooxygenases (MIXED FUNCTION OXYGENASES). In animals, these P-450 enzymes serve two major functions: (1) biosynthesis of steroids, fatty acids, and bile acids; (2) metabolism of endogenous and a wide variety of exogenous substrates, such as toxins and drugs (BIOTRANSFORMATION). They are classified, according to their sequence similarities rather than functions, into CYP gene families (>40% homology) and subfamilies (>59% homology). For example, enzymes from the CYP1, CYP2, and CYP3 gene families are responsible for most drug metabolism.

A barbiturate that is effective as a hypnotic and sedative.
Peroxides
A group of compounds that contain a bivalent O-O group, i.e., the oxygen atoms are univalent. They can either be inorganic or organic in nature. Such compounds release atomic (nascent) oxygen readily. Thus they are strong oxidizing agents and fire hazards when in contact with combustible materials, especially under high-temperature conditions. The chief industrial uses of peroxides are as oxidizing agents, bleaching agents, and initiators of polymerization. (From Hawley's Condensed Chemical Dictionary, 11th ed)
Pyrazolones

Microsomes
Artifactual vesicles formed from the endoplasmic reticulum when cells are disrupted. They are isolated by differential centrifugation and are composed of three structural features: rough vesicles, smooth vesicles, and ribosomes. Numerous enzyme activities are associated with the microsomal fraction. (Glick, Glossary of Biochemistry and Molecular Biology, 1990; from Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
Mixed Function Oxygenases
Widely distributed enzymes that carry out oxidation-reduction reactions in which one atom of the oxygen molecule is incorporated into the organic substrate; the other oxygen atom is reduced and combined with hydrogen ions to form water. They are also known as monooxygenases or hydroxylases. These reactions require two substrates as reductants for each of the two oxygen atoms. There are different classes of monooxygenases depending on the type of hydrogen-providing cosubstrate (COENZYMES) required in the mixed-function oxidation.

Anemia, Pernicious
A megaloblastic anemia occurring in children but more commonly in later life, characterized by histamine-fast achlorhydria, in which the laboratory and clinical manifestations are based on malabsorption of vitamin B 12 due to a failure of the gastric mucosa to secrete adequate and potent intrinsic factor. (Dorland, 27th ed)
Lipid Peroxides
Peroxides produced in the presence of a free radical by the oxidation of unsaturated fatty acids in the cell in the presence of molecular oxygen. The formation of lipid peroxides results in the destruction of the original lipid leading to the loss of integrity of the membranes. They therefore cause a variety of toxic effects in vivo and their formation is considered a pathological process in biological systems. Their formation can be inhibited by antioxidants, such as vitamin E, structural separation or low oxygen tension.
Carbamazepine
An anticonvulsant used to control grand mal and psychomotor or focal seizures. Its mode of action is not fully understood, but some of its actions resemble those of PHENYTOIN; although there is little chemical resemblance between the two compounds, their three-dimensional structure is similar.
Trigeminal Neuralgia
A syndrome characterized by recurrent episodes of excruciating pain lasting several seconds or longer in the sensory distribution of the TRIGEMINAL NERVE. Pain may be initiated by stimulation of trigger points on the face, lips, or gums or by movement of facial muscles or chewing. Associated conditions include MULTIPLE SCLEROSIS, vascular anomalies, ANEURYSMS, and neoplasms. (Adams et al., Principles of Neurology, 6th ed, p187)
Epilepsy, Tonic-Clonic
A generalized seizure disorder characterized by recurrent major motor seizures. The initial brief tonic phase is marked by trunk flexion followed by diffuse extension of the trunk and extremities. The clonic phase features rhythmic flexor contractions of the trunk and limbs, pupillary dilation, elevations of blood pressure and pulse, urinary incontinence, and tongue biting. This is followed by a profound state of depressed consciousness (post-ictal state) which gradually improves over minutes to hours. The disorder may be cryptogenic, familial, or symptomatic (caused by an identified disease process). (From Adams et al., Principles of Neurology, 6th ed, p329)
Seizures
Clinical or subclinical disturbances of cortical function due to a sudden, abnormal, excessive, and disorganized discharge of brain cells. Clinical manifestations include abnormal motor, sensory and psychic phenomena. Recurrent seizures are usually referred to as EPILEPSY or "seizure disorder."
Anticonvulsants
Drugs used to prevent SEIZURES or reduce their severity.
Epilepsy, Generalized
Recurrent conditions characterized by epileptic seizures which arise diffusely and simultaneously from both hemispheres of the brain. Classification is generally based upon motor manifestations of the seizure (e.g., convulsive, nonconvulsive, akinetic, atonic, etc.) or etiology (e.g., idiopathic, cryptogenic, and symptomatic). (From Mayo Clin Proc, 1996 Apr;71(4):405-14)
Epilepsies, Partial
Conditions characterized by recurrent paroxysmal neuronal discharges which arise from a focal region of the brain. Partial seizures are divided into simple and complex, depending on whether consciousness is unaltered (simple partial seizure) or disturbed (complex partial seizure). Both types may feature a wide variety of motor, sensory, and autonomic symptoms. Partial seizures may be classified by associated clinical features or anatomic location of the seizure focus. A secondary generalized seizure refers to a partial seizure that spreads to involve the brain diffusely. (From Adams et al., Principles of Neurology, 6th ed, pp317)

Effect of cyclosporine A on cytochrome P-450-mediated drug metabolism in the partially hepatectomized rat. (1/181)

Despite its hepatotoxic potential, cyclosporine A (CsA) has been reported to positively influence compensatory liver growth. To probe the physiological consequences of CsA on the recovery of liver function, studies were initiated in the 2/3 partially hepatectomized (PHx) rat, taking the recovery of cytochromes P-450-dependent drug metabolism as primary outcome. CsA was administered at a dose of 3. 33 mg/kg/day for 10 days. Drug metabolism was evaluated by the recovery of 14CO2 after administration of isotopically labeled model drugs and by studying the expression of the P-450 transcripts involved in their biotransformation before and 24 to 96 h after PHx. Before PHx, neither the steady-state mRNA nor the in vivo disposition of caffeine (CYP1A2), erythromycin (CYP3A2 and 3A1), or aminopyrine (CYP2B1 and 2C11) were influenced by CsA. Studies 24 h after PHx revealed a 29 to 39% reduction in the elimination of [14C]aminopyrine and [14C]erythromycin, which was unaffected by CsA. Their metabolism at 48 to 96 h after PHx also remained unaffected by CsA. By contrast, postPHx, [14C]caffeine elimination decreased to a level closely proportional to the loss in liver mass. In addition, CsA accelerated the recovery and/or prevented the decrease of caffeine elimination 24 h after PHx but not at later time points, indicating an early, but unsustained, beneficial effect of CsA on the recovery of CYP1A2-mediated activities. These data show that at the critical time of greatest loss in liver mass, CsA has only a selective influence on the biotransformation of cytochrome P-450 protein-dependent activities and that its effect on the regeneration process does not translate into an overall accelerated recovery of the hepatic drug-metabolizing function.  (+info)

L-365,260 inhibits in vitro acid secretion by interacting with a PKA pathway. (2/181)

The aim of this study was to analyse the antisecretory mechanism of L-365,260 in vitro in isolated rabbit gastric glands. We showed that compound L-365,260, described as a non-peptide specific competitive CCK-B receptor antagonist, was able to dose-dependently inhibit [14C]-aminopyrine accumulation induced by histamine (10(-4) M), carbachol (5x10(-5) M), 3-isobutyl-1-methyl-xanthine (IBMX) (5x10(-6) M) and forskolin (5x10(-7) M) with similar IC50 values respectively of 1.1+/-0.6x10(-7) M, 1.9+/-1.2x10(-7) M, 4.2+/-2.0x10(-7) M and 4.0+/-2.8x10(-7) M. We showed that L-365,260 acted beyond receptor activation and production of intracellular second messengers and that it had no action on the H+/K+ -ATPase. We found that L-365,260 inhibited cyclic AMP-induced [14C]-aminopyrine accumulation in digitonin-permeabilized rabbit gastric glands, suggesting that this compound acted, at least in part, as an inhibitor of the cyclic AMP-dependent protein kinase (PKA) pathway.  (+info)

Demethylation capacity of human fetal adrenal mitochondrial cytochrome P-450 in vitro. (3/181)

AIM: To explore the capacity and characteristics of adrenal mitochondria to metabolize xenobiotics in vitro in human fetus. METHODS: Subcellular fractions of fetal adrenal were prepared by differential centrifugation. Mitochondrial P-450 system was proved by spectral analyses and SDS-PAGE. The formaldehyde formation contents were measured with Nash reagent. RESULTS: The erythromycin N-demethylation linearly increased in the protein concentration (1-4 mg)- and incubation time (10-30 min)-dependent manners. A typical concentration-effect relationship appeared with erythromycin 0.067-1 mmol.L-1 and a positive correlation (r = 0.641, P < 0.05) existed between erythromycin N-demethylation and gestation months. The N-demethylation values (nmol.s-1/g protein) of erythromycin (2.7 +/- 0.8), benzfetamine (1.1 +/- 0.5), and aminophenazone (0.9 +/- 0.4) in mitochondria were 89% (P > 0.05), 162% (P < 0.01), and 62% (P < 0.01), respectively, of those in microsomes. There was correlation between mitochondria and microsomes in the N-demethylation of erythromycin (r = 0.708, P < 0.05) and benzfetamine (r = 0.707, P < 0.05). Troleandomycin stimulated erythromycin N-demethylation in adrenal mitochondria as well as in adrenal and liver microsomes in vitro. CONCLUSION: Fetal adrenal mitochondria, with multiple P-450 isoforms and greater capacity of demethylation, play a role in drug-metabolism during fetal development.  (+info)

Expression of rab11a N124I in gastric parietal cells inhibits stimulatory recruitment of the H+-K+-ATPase. (4/181)

Stimulation of the gastric parietal cell results in a massive redistribution of H+-K+-ATPase from cytoplasmic tubulovesicles to the apical plasma membrane. Previous studies have implicated the small GTPase rab11 in this process. Using matrix-assisted laser desorption mass spectrometry, we confirmed that rab11 is associated with H+-K+-ATPase-enriched gastric microsomes. A stoichiometry of one rab11 per six copies of H+-K+-ATPase was estimated. Furthermore, rab11 exists in at least three forms on rabbit gastric microsomes: the two most prominent resemble rab11a, whereas the third resembles rab11b. Using an adenoviral expression system, we expressed the dominant negative mutant rab11a N124I in primary cultures of rabbit parietal cells under the control of the tetracycline transactivator protein (tTA). The mutant was well expressed with a distribution similar to that of the H+-K+-ATPase. Stimulation of these cultures with histamine and IBMX was assessed by measuring the aminopyrine (AP) uptake relative to resting cells (AP index). In experiments on six culture preparations, stimulated uninfected cells gave an AP index of 10.0 +/- 2.9, whereas parallel cultures expressing rab11a N124I were poorly responsive to stimulation, with a mean AP index of 3.2 +/- 0. 9. Control cultures expressing tTA alone or tTA plus actin responded equally well to stimulation, giving AP index values of 9.0 +/- 3.1 and 9.6 +/- 0.9, respectively. Thus inhibition by rab11a N124I is not simply due to adenoviral infection. The AP uptake data were confirmed by immunocytochemistry. In uninfected cells, H+-K+-ATPase demonstrated a broad cytoplasmic distribution, but it was cleared from the cytoplasm and associated with apically derived membranes on stimulation. In cells expressing rab11a N124I, H+-K+-ATPase maintained its resting localization on stimulation. Furthermore, this effect could be alleviated by culturing infected cells in the presence of tetracycline, which prevents expression of the mutant rab11. We therefore conclude that rab11a is the prominent GTPase associated with gastric microsomes and that it plays a role in parietal cell activation.  (+info)

Responsiveness of beta-escin-permeabilized rabbit gastric gland model: effects of functional peptide fragments. (5/181)

We established a beta-escin-permeabilized gland model with the use of rabbit isolated gastric glands. The glands retained an ability to secrete acid, monitored by [14C]aminopyrine accumulation, in response to cAMP, forskolin, and histamine. These responses were all inhibited by cAMP-dependent protein kinase inhibitory peptide. Myosin light-chain kinase inhibitory peptide also suppressed aminopyrine accumulation, whereas the inhibitory peptide of protein kinase C or that of calmodulin kinase II was without effect. Guanosine-5'-O-(3-thiotriphosphate) (GTPgammaS) abolished cAMP-stimulated acid secretion concomitantly, interfering with the redistribution of H+-K+-ATPase from tubulovesicles to the apical membrane. To identify the targets of GTPgammaS, effects of peptide fragments of certain GTP-binding proteins were examined. Although none of the peptides related to Rab proteins showed any effect, the inhibitory peptide of Arf protein inhibited cAMP-stimulated secretion. These results demonstrate that our new model, the beta-escin-permeabilized gland, allows the introduction of relatively large molecules, e.g., peptides, into the cell, and will be quite useful for analyzing signal transduction of parietal cell function.  (+info)

Regulation and function of p38 protein kinase in isolated canine gastric parietal cells. (6/181)

We examined the regulation and functional role of p38 kinase in gastric acid secretion. p38 kinase was immunoprecipitated from cell lysates of highly purified gastric parietal cells in primary culture, and its activity was quantitated by in vitro kinase assay. Carbachol effects were dose- and time-dependent, with a maximal 10-fold stimulatory effect detected after 30 min of incubation. SB-203580, a highly selective inhibitor of p38 kinase, blocked carbachol induction of p38 kinase activity, with maximal inhibition at 10 microM. Stimulation by carbachol was unaffected by preincubation of parietal cells with the intracellular Ca(2+) chelator BAPTA-AM, but incubation of cells in Ca(2+)-free medium led to a 50% inhibition of carbachol induction of p38 kinase activity. Because some of the effects of carbachol are mediated by the small GTP-binding protein Rho, we examined the role of Rho in carbachol induction of p38 kinase activity. We tested the effect of exoenzyme C3 from Clostridium botulinum (C3), a toxin known to ADP-ribosylate and specifically inactivate Rho. C3 led to complete ADP-ribosylation of Rho, and it inhibited carbachol induction of p38 kinase by 50%. We then tested the effect of SB-203580 and C3 on carbachol-stimulated uptake of [(14)C]aminopyrine (AP). Inhibition of p38 kinase by SB-203580 led to a dose-dependent increase in AP uptake induced by carbachol, with maximal (threefold) effect at 10 microM SB-203580. Similarly, preincubation of parietal cells with C3 led to a twofold increase in AP uptake induced by carbachol. Thus carbachol induces a cascade of events in parietal cells that results in activation of p38 kinase through signaling pathways that are at least in part dependent on Rho activation and on the presence of extracellular Ca(2+). p38 kinase appears to inhibit gastric acid secretion.  (+info)

Tryptophan operon read-through. Isolation and characterization of an abnormally long tryptophan synthetase alpha subunit from a frame-shift mutant of Escherichia coli. (7/181)

A new mutant strain of Escherichia coli, strain ICR-47, contains a frame-shift mutation in the trpA gene, the gene most distal to the operator in the trp operon. Mapping experiments indicate that the lesion is located at a site within 10 to 15% of the end of this gene. The mutation results in "out-of-phase" translation of the distal portion of the trp mRNA; normal translational termination signal(s) are not encountered and a trpA gene product longer than the wild type protein is produced. As with the other enzymes produced from this operon, the in vivo level of the altered protein (the alpha subunit of the tryptophan synthetase enzyme complex) is controlled by exogenous L-tryptophan. The altered alpha subunit from the strain ICR-47 has been isolated and characterized. Molecular weight estimations indicate a molecular weight of approximately 37,000, an increase beyond the wild type enzyme corresponding to an additional 50 to 70 amino acid residues. The protein has a new COOH-terminal amino acid sequence. Results of preliminary hybridization experiments suggest that the ICR-47 mRNA, which is necessarily longer than that needed to code for wild type enzyme, is not detectably different in size from wild type mRNA. The enzymatic properties of the ICR-47 alpha subunit indicates a greatly reduced ability of the mutant subunit to combine functionally with wild type beta2 subunit, the second protein component in the tryptophan synthetase enzyme complex. In contrast, only 40 to 50% of the intrinsic enzymatic activity of the alpha subunit is lost.  (+info)

A proposed mechanism for the potentiation of cAMP-mediated acid secretion by carbachol. (8/181)

Acid secretion in isolated rabbit gastric glands was monitored by the accumulation of [(14)C]aminopyrine. Stimulation of the glands with carbachol synergistically augmented the response to dibutyryl cAMP. The augmentation persisted even after carbachol was washed out and was resistant to chelated extracellular Ca(2+) and to inhibitors of either protein kinase C or calmodulin kinase II. Cytochalasin D at 10 microM preferentially blocked the secretory effect of carbachol and its synergism with cAMP, whereas it had no effect on histamine- or cAMP-stimulated acid secretion within 15 min. Cytochalasin D inhibited the carbachol-stimulated intracellular Ca(2+) concentration ([Ca(2+)](i)) increase due to release from the Ca(2+) store. Treatment of the glands with cytochalasin D redistributed type 3 inositol 1,4,5-trisphosphate receptor (the major subtype in the parietal cell) from the fraction containing membranes of large size to the microsomal fraction, suggesting a dissociation of the store from the plasma membrane. These findings suggest that intracellular Ca(2+) release by cholinergic stimulation is critical for determining synergism with cAMP in parietal cell activation and that functional coupling between the Ca(2+) store and the receptor is maintained by actin microfilaments.  (+info)

Characterization of oxyntic glands isolated from the rat gastric mucosaCharacterization of oxyntic glands isolated from the rat gastric mucosa
The design of methods useful for the preparation of viable glands and cells from the gastric mucosa allowed detailed studies on the mechanisms that regulate gastric acid secretion. The preparation of rabbit gastric glands was the first suitable method to be used and a number of important scientific contributions have been accomplished with this method. Using this method we studied the effect of CCK-like peptides on [14C]aminopyrine accumulation stimulated by histamine, in order to fmd out whether such peptides can inhibit the production of acid in the parietal cell. We also developed a method for the study of viable rat gastric glands that allowed comparative studies in the rat species.. In rabbit gastric glands CCK-like pep tides inhibited histamine stimulated acid formation whereas gastrin peptides were ineffective. The most potent and efficacious peptides were CCK 8 and the cholecystokinetic amphibian decapeptide cemlein reducing the maximal histamine stimulation of aminopyrine accumulation ...

Dietary restriction of energy and sugar results in a reduction in human cytochrome P450 2E1 activity. | DIAL.pr - BOREALDietary restriction of energy and sugar results in a reduction in human cytochrome P450 2E1 activity. | DIAL.pr - BOREAL
Dietary habits are often considered as a pathogenic factor for fatty liver. The impact of dietary intake and steatosis on drug metabolism remains poorly investigated. Our aim was to assess the effect of dietary intake on in vivo cytochrome P450 (CYP) activities in eleven patients with abnormal liver function tests potentially due to fatty liver and associated with a high-sugar diet. Liver function tests, liver volume, aminopyrine breath test (ABT) and chlorzoxazone (CZ) pharmacokinetics (area under the curve, AUC) which are known to reflect CYP2E1 activity were evaluated before and after 2 months restriction of dietary sugar intake. Features at inclusion were an increased BMI (30.3 (SD 3.2) kg/m2), high hepatic volume (1.96 (SD 0.48) litres), hyperechogenic liver parenchyma, elevated liver enzyme activities (alanine aminotransferase (EC 2.6.1.2) 58.6 (SD 17.4) IU/1 with alanine aminotransferase: aspartate aminotransferase (EC 2.6.1.1) ratio , 1), together with a normal ABT value (0.68 (SD 0.21)% ...

With that encouragement Axelrod quickly showed that amphetamine was rapidly metabolized in rabbit liver slices. He went on to define the co-factor requirements for the reaction finding that NADPH was required; similar to observations of Bert LaDu in his studies on aminopyrine demethylation9.Axelrod then determined the sub-cellular location of the activity by using methods developed by Hogeboom and Schneider10. This newly defined microsomal oxidizing system was soon shown to be responsible for the metabolism of a wide variety of drugs and other chemicals.. Ref: 1V.R.Potter and C.A.Elvehjem, J.Biol.

The involvement of a thromboxane (TX) A2-like substance in the decrease of mucosal blood flow (MBF) and occurrence of gastric erosions in rats under water-immersion stress was examined. MBF was estimated by aminopyrine clearance. Stress increased acid output without a parallel increase in MBF and caused erosions. OKY-046, an inhibitor of TXA2 synthesis, and ONO-11120, an antagonist of TXA2 receptors, increased MBF during stress in parallel with an increase in acid output, and erosions did not form. In another experiment, the effects of a TXA2-like substance on MBF during vagal stimulation were examined. Although vagal stimulation alone increased acid output, there were no erosions in the stomach, probably because MBF was increased in parallel with acid output. Intra-arterial administration of a TXA2-like substance formed by the metabolism of arachidonic acid in the blood reduced MBF during vagal stimulation.

The effect of ethanol on N-demethylation of aminopyrine in rat liver slices and in the microsomal fraction and on microsomal hydroxylation of pentobarbital and aniline was studied. With liver slices N-demethylation of aminopyrine was stimulated by 35-40% at low ethanol concentrations (2mm), whereas no stimulation occurred at high concentrations (100mm). With the liver microsomal fraction, an inhibitory effect was observed only at high ethanol concentrations (100mm). This was also observed with the other drugs studied. In agreement with these results, only at a high concentration did ethanol interfere with the binding of drug substrates to cytochrome P-450. Further, as previously reported, ethanol produced a reverse type I spectral change when added to the liver microsomal fraction. Evidence that this spectral change is due to removal of substrate, endogenously bound to cytochrome P-450, is reported. A dual effect of ethanol is assumed to explain the present findings; in liver slices, at a low ...

Comparative studies of in vitro drug metabolism by hepatic and extrahepatic tissues have been complicated by the use of a single experimental tissue, few animal species, and variable experimental conditions. In an attempt to minimize these complications, liver, lung and kidney from rat, mouse, rabbit, hamster, and guinea pig were assayed for standard microsomal and soluble fraction enzymes involved in drug biotransformation. For all species, liver was the most active organ. Kidney and lung activities were usually 15%-40% of those found in liver, with kidney slightly more active than lung. No single species demonstrated total superiority in its drug-metabolizing ability, although hamster showed a large number of instances of greatest activity. The rat was a surprisingly poor representative of drug-metabolizing ability; it was superior to the other four species in less than 25% of the instances studied. All species appeared to N-demethylate aminopyrine equally except for high pulmonary and nearly ...

SMART: Secondary literature for RasGEFN domainSMART: Secondary literature for RasGEFN domain
We previously reported that both carbachol and epidermal growth factor (EGF) are potent inducers of the extracellular signal-regulated protein kinases (ERKs) in isolated gastric canine parietal cells and that induction of these kinases leads to acute inhibitory and chronic stimulatory effects on gastric acid secretion. In this study we investigated the molecular mechanisms responsible for these effects. Both carbachol (100 microM) and EGF (10 nM) induced Ras activation. The role of Ras in ERK2 induction was examined by transfecting parietal cells with a vector expressing hemoagglutinin (HA)-tagged ERK2 (HA-ERK2) together with a dominantly expressed mutant (inactive) ras gene. HA-ERK2 activity was quantitated by in-gel kinase assays. Dominant negative Ras reduced carbachol induction of HA-ERK2 activity by 60% and completely inhibited the stimulatory effect of EGF. Since Ras activation requires the assembly of a multiprotein complex, we examined the effect of carbachol and EGF on tyrosyl ...

Purification and characterization of hepatic P-450IIE1 from acetone-treated mice | DSpace-CRIS DBCF UNISI
A new cytochrome P-450 isozyme (Mr = 52,000) was purified to apparent electrophoretic homogeneity from hepatic microsomes of mice treated with acetone and its biochemical, spectral, and immunological properties characterized. Several criteria indicated that the purified cytochrome was distinct from the known mouse P-450 isozymes. The absolute spectrum of its oxidized form indicated that it was in the high spin state. In a reconstituted system, it showed low catalytic activities towards 7-ethoxycoumarin, aminopyrine, and coumarin, whereas it catalyzed the oxidation of aniline, acetone, dimethylnitrosamine with high turnover number. The mouse enzyme was immunoreactive with polyclonal antibodies against rat P-450IIE1 and exhibited an NH2-terminal aminoacid sequence with a high homology to that of rat-P-450IIE1. Based upon the above catalytic, spectral, immunological and structural properties, the purified mouse P-450 appears to be the ortholog of previously described P-450IIE1(s) of other species ...

Serum triglycerides are hydrolyzed to glycerol and free fatty acids by lipase. In the presence of ATP and glycerol kinase (GK), the glycerol is converted to glycerol-1-phosphate. The glycerol-1-phosphate is then oxidized by glycerol phosphate oxidase (GPO) to yield hydrogen peroxide. The condensation of hydrogen peroxide with 4-chlorophenol and 4-aminophenazone (4-AA) in the presence of peroxidase (POD) produces a red colored quinonimine dye which absorbs at, or near 500nm. The intensity of the colored complex formed is directly proportional to the triglycerides concentration of the sample ...

Abstract: Metabolism of aminopyrine, sodium benzoate and toxicity of cyclophosphamide were studied in 185 male rats under conditions of various content of vitamin B1 in the animals. Deficiency of thiamin led to an increase in excretion of 4-aminoantipyrine and especially of its acetylated derivative. After administration of thiamin metabolism of aminopyrine was not distinctly altered, while thiamin diphosphate inhibited the drug biotransformation. In deficiency of vitamin B1 transformation of benzoic acid into hippuric acid was inhibited but formation of glucuronides was elevated. Administration of thiamin or thiamin diphosphate stimulated the benzoic acid conjugation and inhibited the glucuronides formation. Deficiency of vitamin B1 accelerated the cyclophosphamide toxicity. Preadministration of thiamin and especially of thiamin diphosphate decreased the toxic effect of cyclophosphamide ...

Ipl Acne Therapy Treatment | Spirits List
How does IPL work for acne?. There are three forms of IPL therapy for acne - LHE Therapy, Blue-Light Therapy and IPL with medication. The choice will depend on what results youre looking for and what your dermatologist suggests as the most effective for your individual acne spots. LHE therapy uses both heat and light as the source to treat acne. The FDA has actually approved one IPL treatment that involves green light waves and heat. This form of IPL is meant to treat mild to moderate acne and more than likely, over a period of time. The whole process has been known to reduce the size of oil glands and kill the dirt bacteria in pores that create acne.. Blue-Light therapy is similar to LHE minus the UV radiation. It only makes sense that less UV radiation equals less damage on your skin. This form of IPL will have the same effect on killing the dirt bacteria but with less side effects than the LHE therapy.

Gastrointestinal malignancies are strongly linked to chronic inflammation (25-29). Gastric tumorigenesis in K19-Wnt1/C2mE mice was also recently shown to be suppressed by knockout of either TNFα or its receptor TNFR1, suggesting that TNFα-dependent inflammation plays a key role in the development of gastric cancer (30). Furthermore, the development of SPEM in response to acute parietal cell loss is dependent on the recruitment of macrophages to the gastric epithelium (31). Together, these findings suggest that inflammation triggers the histopathologic alterations of gastric epithelium that leads to tumor development. We have now shown that the inflammation-associated ROS plays a key role in the parietal cell loss that is an early and critical step in the development of SPEM, and the subsequent formation of gastric tumors. The accumulation of ROS triggers the p38MAPK-p16INK4a/p19ARF signaling pathway selectively in parietal cells and the consequent induction of parietal cell loss. In fact, ...

Breath test11
  • Background: There are few data on the use of the 13 C-aminopyrine breath test to evaluate the severity of disease in patients with hepatitis C virus-related chronic liver disease, although these patients represent one of the most important problems in clinical hepatology. (elsevier.com)
  • Aims: To compare 13 C-aminopyrine breath test results of patients with hepatitis C virus-related chronic hepatitis and Child-Pugh class A cirrhosis with those of normal subjects, and to evaluate different methods of expressing 13 C-aminopyrine breath test results. (elsevier.com)
  • Methods: Twenty-four patients with hepatitis C virus-related chronic hepatitis and 17 patients with Child-Pugh class A cirrhosis underwent 13 C-aminopyrine breath test. (elsevier.com)
  • 13 C-Aminopyrine breath test results were expressed as a percentage of the administered dose of 13 C recovered per hour (% dose/h) and the cumulative percentage of administered dose of 13 C recovered over time (% dose cum). (elsevier.com)
  • The fibrosis score showed a significant inverse correlation with the 13 C-aminopyrine breath test result (% dose/h) at 30 min (rs = - 0.409, P = 0.05). (elsevier.com)
  • The 13 C-aminopyrine breath test results (% dose cum) at 30. (elsevier.com)
  • The 13 C-aminopyrine breath test result (% dose cum) was also able to distinguish between normal subjects and chronic hepatitis patients with high but not low fibrosis scores. (elsevier.com)
  • Both 13 C-aminopyrine breath test results (% dose/h and % dose cum) at 120 min allowed the differentiation between normal subjects and chronic hepatitis patients with high (≥ 6) necro-inflammatory activity. (elsevier.com)
  • Conclusions: In patients with hepatitis C virus-related chronic liver disease, the 13 C-aminopyrine breath test proved to be safe and easy to perform, and was able to evaluate different degrees of liver function impairment which were partly correlated to clinical and histological evaluation. (elsevier.com)
  • In future studies, 13 C-aminopyrine breath test results should be expressed in a standardized fashion to permit comparison. (elsevier.com)
  • A breath test with 13C-labeled aminopyrine has been used as a non-invasive measure of CYTOCHROME P-450 metabolic activity in LIVER FUNCTION TESTS . (bvsalud.org)

  • The aminopyrine breath test has been shown to be a sensitive noninvasive indicator of liver cell dysfunction. (nih.gov)
  • In a search for a noninvasive method of monitoring the effects of methotrexate therapy, we have investigated the use of the aminopyrine breath test in patients receiving methotrexate for the treatment of severe psoriasis. (nih.gov)
  • The [14C]-aminopyrine breath test was performed in 20 normal control subjects, 32 patients with psoriasis receiving methotrexate therapy, and 8 patients with histologically confirmed cirrhosis of differing etiology. (nih.gov)
  • The aminopyrine breath test was only able to detect the later severe stages of methotrexate hepatotoxicity, grade III, when fibrosis occurs, before established cirrhosis was present. (nih.gov)
  • Our data suggests that the aminopyrine breath test is not a sensitive indicator for the detection of early methotrexate-induced hepatotoxicity, (stages I and II), but will detect the precirrhotic stage III change. (nih.gov)
  • Consequently, we recommend that a liver biopsy should be performed annually in all psoriatic patients receiving methotrexate, to detect histological damage, especially when the aminopyrine breath test score falls below the 95% confidence limits of normal. (nih.gov)
  • 7. Aminopyrine breath test predicts liver-related events and death in HCV-related cirrhosis on SVR after DAA therapy. (nih.gov)
  • A breath test with 13C-labeled aminopyrine has been used as a non-invasive measure of CYTOCHROME P-450 metabolic activity in LIVER FUNCTION TESTS . (nih.gov)
  • To determine whether Type II diabetes or glyburide affect hepatic drug metabolism, the authors used 13 C‐labeled aminopyrine and caffeine breath tests as in vivo probes of the hepatic cytochrome P450 and P 1 450 enzyme activities respectively in six subjects with Type II diabetes (4 women, 2 men). (northwestern.edu)
  • The caffeine and aminopyrine breath tests (CBT, ABT) were performed sequentially while fasting before the start of glyburide treatment (5 mg daily) and at weekly intervals for 4 weeks. (northwestern.edu)
  • Type II diabetes that is poorly controlled by diet alone is not associated with alterations of the hepatic drug metabolizing enzymes as judged by the caffeine and aminopyrine breath tests. (northwestern.edu)

Enzymes1
  • Both cryoprotectant media were equally efficient at preserving enzyme activities in the hepatocytes over 7 days at -80 degrees C.
