The B protomer binds cholera toxin to intestinal epithelial cells, and facilitates the uptake of the A1 fragment. The A1 catalyzed transfer of ADP-RIBOSE to the alpha subunits of heterotrimeric G PROTEINS activates the production of CYCLIC AMP. Increased levels of cyclic AMP are thought to modulate release of fluid and electrolytes from intestinal crypt cells.

Tissue pharmacokinetics, inhibition of DNA synthesis and tumor cell kill after high-dose methotrexate in murine tumor models. (1/6741)

In Sarcoma 180 and L1210 ascites tumor models, the initial rate of methotrexate accumulation in tumor cells in the peritoneal cavity and in small intestine (intracellularly) after s.c. doses up to 800 mg/kg, showed saturation kinetics. These results and the fact that initial uptake in these tissues within this dosage range was inhibited to the expected relative extent by the simultaneous administration of leucovorin suggest that carrier mediation and not passive diffusion is the major route of drug entry at these extremely high doses. Maximum accumulation of intracellular drug occurred within 2 hr and reached much higher levels in small intestine than in tumor cells at the higher dosages. At a 3-mg/kg dose of methotrexate s.c., intracellular exchangeable drug levels persisted more than four times longer in L1210 cells than in small intestine, but differences in persistence (L1210 cell versus gut) diminished markedly with increasing dosage. At 96 mg/kg, the difference in persistence was less than 2-fold. In small intestine and L1210 cells, theduration of inhibition of DNA synthesis at different dosages correlated with the extent to which exchangeable drug was retained. Toxic deaths occurred when inhibition in small intestine lasted longer than 25 to 30 hr. Recovery of synthesis in small intestine and L1210 cells occurred synchronously and only below dosages of 400 mg/kg. Within 24 hr after dosages of greater than 24 mg/kg, the rate of tumor cell loss increased to a point characterized by a single exponential (t1/2=8.5 hr). The total cell loss, but not the rate of cell loss, was dose dependent.  (+info)

Analysis of the effects of food and of digestive secretions on the small intestine of the rat. 1. Mucosal morphology and epithelial replacement. (2/6741)

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)

Energy depletion differently affects membrane transport and intracellular metabolism of riboflavin taken up by isolated rat enterocytes. (3/6741)

Isolated rat enterocytes, both normal and those de-energized with rotenone, were used to study the energy dependence of membrane and intracellular intestinal riboflavin transport in vitro. Membrane and intracellular transport were investigated by using short (3 min) and long (20 min) incubation times, respectively. For both types of cells and incubation times, [3H]-riboflavin uptake presented a saturable component prevailing at physiologic intraluminal concentrations. At 3 min incubation, saturable [3H]-riboflavin transport was apparently an energy-independent process with high affinity and low capacity. Values of the saturable component and its apparent constants, Km and Jmax, did not differ in normal and de-energized enterocytes. At 20 min incubation, saturable [3H]-riboflavin transport was a strictly energy-dependent process in which values of the saturable component were significantly greater in normal than in de-energized enterocytes. Km values did not differ in the two types of cells and were unmodified over 3 min, whereas in normal enterocytes, Jmax at 20 min [6.25 +/- 0.2 pmol/(mg protein. 20 min)] was significantly greater than at 3 min [2.67 +/- 0.33 pmol/(mg protein. 3 min)] and compared with de-energized enterocytes at 20 min [2.54 +/- 0.16 pmol/(mg protein. 20 min)]. Both membrane and intracellular events were inhibited by unlabeled riboflavin and analogs, which are good substrates for flavokinase, thus demonstrating the paramount role of this enzyme in riboflavin intestinal transport.  (+info)

Interaction of lipopolysaccharide with human small intestinal lamina propria fibroblasts favors neutrophil migration and peripheral blood mononuclear cell adhesion by the production of proinflammatory mediators and adhesion molecules. (4/6741)

Fibroblasts are important effector cells having a potential role in augmenting the inflammatory responses in various diseases. In infantile diarrhea caused by enteropathogenic Escherichia coli (EPEC), the mechanism of inflammatory reactions at the mucosal site remains unknown. Although the potential involvement of fibroblasts in the pathogenesis of cryptococcus-induced diarrhea in pigs has been suggested, the precise role of lamina propria fibroblasts in the cellular pathogenesis of intestinal infection and inflammation caused by EPEC requires elucidation. Earlier we reported the lipopolysaccharide (LPS)-induced cell proliferation, and collagen synthesis and downregulation of nitric oxide in lamina propria fibroblasts. In this report, we present the profile of cytokines and adhesion molecules in the cultured and characterized human small intestinal lamina propria fibroblasts in relation to neutrophil migration and adhesion in response to lipopolysaccharide (LPS) extracted from EPEC 055:B5. Upon interaction with LPS (1-10 micrograms/ml), lamina propria fibroblasts produced a high level of proinflammatory mediators, interleukin (IL)-1alpha, IL-1beta, IL-6, IL-8, tumor necrosis factor (TNF)-alpha and cell adhesion molecules (CAM) such as intercellular cell adhesion molecule (ICAM), A-CAM, N-CAM and vitronectin in a time-dependent manner. LPS induced cell-associated IL-1alpha and IL-1beta, and IL-6, IL-8 and TNF-alpha as soluble form in the supernatant. Apart from ICAM, vitronectin, A-CAM, and N-CAM proteins were strongly induced in lamina propria fibroblasts by LPS. Adhesion of PBMC to LPS-treated lamina propria fibroblasts was ICAM-dependent. LPS-induced ICAM expression in lamina propria fibroblasts was modulated by whole blood, PBMC and neutrophils. Conditioned medium of LPS-treated lamina propria fibroblasts remarkably enhanced the neutrophil migration. The migration of neutrophils was inhibited by anti-IL-8 antibody. Co-culture of fibroblasts with neutrophils using polycarbonate membrane filters exhibited time-dependent migration of neutrophils. These findings indicate that the coordinate production of proinflammatory cytokines and adhesion molecules in lamina propria fibroblasts which do not classically belong to the immune system can influence the local inflammatory reactions at the intestinal mucosal site during bacterial infections and can influence the immune cell population residing in the lamina propria.  (+info)

Regulatory sequences of the mouse villin gene that efficiently drive transgenic expression in immature and differentiated epithelial cells of small and large intestines. (5/6741)

Villin is an early marker of epithelial cells from the digestive and urogenital tracts. Indeed villin is expressed in the stem cells and the proliferative cells of the intestinal crypts. To investigate the underlying molecular mechanisms and particularly those responsible for the restricted tissue specificity, a large genomic region of the mouse villin gene has been analyzed. A 9-kilobase (kb) regulatory region of the mouse villin gene (harboring 3.5 kb upstream the transcription start site and 5.5 kb of the first intron) was able to promote transcription of the LacZ reporter gene in the small and large intestines of transgenic mice, in a transmissible manner, and thus efficiently directed subsequent beta-galactosidase expression in epithelial cells along the entire crypt-villus axis. In the kidney, the transgene was also expressed in the epithelial cells of the proximal tubules but is likely sensitive to the site of integration. A construct lacking the first intron restricted beta-galactosidase expression to the small intestine. Thus, the 9-kb genomic region contains the necessary cis-acting elements to recapitulate the tissue-specific expression pattern of the endogenous villin gene. Hence, these regulatory sequences can be used to target heterologous genes in immature and differentiated epithelial cells of the small and/or large intestinal mucosa.  (+info)

Calcium responses induced by acetylcholine in submucosal arterioles of the guinea-pig small intestine. (6/6741)

1. Calcium responses induced by brief stimulation with acetylcholine (ACh) were assessed from the fluorescence changes in fura-2 loaded submucosal arterioles of the guinea-pig small intestine. 2. Initially, 1-1.5 h after loading with fura-2 (fresh tissues), ACh increased [Ca2+]i in a concentration-dependent manner. This response diminished with time, and finally disappeared in 2-3 h (old tissues). 3. Ba2+ elevated [Ca2+]i to a similar extent in both fresh and old tissues. ACh further increased the Ba2+-elevated [Ca2+]i in fresh tissues, but reduced it in old tissues. Responses were not affected by either indomethacin or nitroarginine. 4. In fresh mesenteric arteries, mechanical removal of endothelial cells abolished the ACh-induced increase in [Ca2+]i, with no alteration of [Ca2+]i at rest and during elevation with Ba2+. 5. In the presence of indomethacin and nitroarginine, high-K+ solution elevated [Ca2+]i in both fresh and old tissues. Subsequent addition of ACh further increased [Ca2+]i in fresh tissues without changing it in old tissues. 6. Proadifen, an inhibitor of the enzyme cytochrome P450 mono-oxygenase, inhibited the ACh-induced changes in [Ca2+]i in both fresh and Ba2+-stimulated old tissues. It also inhibited the ACh-induced hyperpolarization. 7. In fresh tissues, the ACh-induced Ca2+ response was not changed by apamin, charybdotoxin (CTX), 4-aminopyridine (4-AP) or glibenclamide. In old tissues in which [Ca2+]i had previously been elevated with Ba2+, the ACh-induced Ca2+ response was inhibited by CTX but not by apamin, 4-AP or glibenclamide. 8. It is concluded that in submucosal arterioles, ACh elevates endothelial [Ca2+]i and reduces muscular [Ca2+]i, probably through the hyperpolarization of endothelial or smooth muscle membrane by activating CTX-sensitive K+ channels.  (+info)

Expression of arginase II and related enzymes in the rat small intestine and kidney. (7/6741)

Arginase, which catalyzes the conversion of arginine to urea and ornithine, and consists of a liver-type (arginase I) and a non-hepatic type (arginase II). Arginine is also used for the synthesis of nitric oxide and creatine phosphate, while ornithine is used for the synthesis of polyamines and proline, and thus collagen. Arginase II mRNA and protein are abundant in the intestine (most abundant in the jejunum and less abundant in the ileum, duodenum, and colon) and kidney of the rat. In the kidney, the levels of arginase II mRNA do not change appreciably from 0 to 8 weeks of age. In contrast, arginase II mRNA and protein in the small intestine are not detectable at birth, appear at 3 weeks of age, the weaning period, and their levels increase up to 8 weeks. On the other hand, mRNAs for ornithine aminotransferase (OAT), ornithine decarboxylase, and ornithine carbamoyltransferase (OCT) are present at birth and their levels do not change much during development. Arginase II is elevated in response to a combination of bacterial lipopolysaccharide, dibutyryl cAMP, and dexamethasone in the kidney, but is not affected by these treatments in the small intestine. Immunohistochemical analysis of arginase II, OAT, and OCT in the jejunum revealed their co-localization in absorptive epithelial cells. These results show that the arginase II gene is regulated differentially in the small intestine and kidney, and suggest different roles of the enzyme in these two tissues. The co-localization of arginase II and the three ornithine-utilizing enzymes in the small intestine suggests that the enzyme is involved in the synthesis of proline, polyamines, and/or citrulline in this tissue.  (+info)

Cellular uptake of biotin: mechanisms and regulation. (8/6741)

This review describes our knowledge of biotin transport in the small intestine of humans and other mammals and presents recent findings in the area. Previous studies have shown that biotin transport across the brush border membrane of the small intestinal absorptive cells occurs via a carrier-mediated, Na+ gradient-dependent, electroneutral mechanism. Exit of biotin out of the enterocyte, i.e., transport across the basolateral membrane, also occurs via a carrier-mediated process, but the process is Na+ independent and electrogenic. Recent studies from our laboratory have shown that the uptake process of biotin in Caco-2 cells, a human-derived cultured intestinal epithelial cell line, are under the cellular regulation of both a protein kinase C- and a Ca/calmodulin-mediated pathway. In addition, the uptake process is shared by another water-soluble vitamin, pantothenic acid. For the first time, other recent studies have detected the existence of a Na+-dependent, carrier-mediated mechanism for biotin uptake at the apical membrane of colonocytes, which could theoretically mediate absorption of the biotin synthesized by colonic microflora. This system was again found to be shared by pantothenic acid, which is also synthesized by the normal microflora of the large intestine.  (+info)

Objective The purpose of this study is to use porcine small intestinal submucosa (PSIS) as a corneal graft in 10 cases of staphyloma in dogs. Materials & Methods Corneal grafts using porcine small intestinal submucosa (PSIS) were performed in 10 dogs with staphyloma. After general anesthesia and aseptic preparation, nonviable tissue was removed from the recipient staphyloma bed. The iris was pushed back into the anterior chamber before carefully detached from the corneal wound. The PSIS graft sheet was rehydrated in lactate Ringers solution for 5 minutes prior to the placement on to the corneal lesion, and interruptedly sutured to the cornea with 8/10 polyglactin. The third eyelid was sutured on to the palpebral conjunctiva with simple Mattress using 6/0 silk for 14 days. Result Within 7 weeks, all dogs returned to normal vision with pupillary light and menace reflexes. Minimal anterior synechia and scar in accordance with the size of prior corneal lesion were present. Conclusion PSIS is ...

N2 - The distributions of peptide‐containing nerve fibers and cell bodies in the canine small intestine were determined with antibodies raised against seven peptides: enkephalin, gastrin‐releasing peptide (GRP), neuropeptide Y, neurotensin, somatostatin, substance P, and vasoactive intestinal peptide (VIP). Immunoreactive nerve cell bodies and fibers were found for each peptide except neurotensin. In the muscle layers there were numerous substance P, VIP, and enkephalin fibers, fewer neuropeptide Y fibers, and very few GRP or somatostatin fibers. The mucosa contained many VIP and substance P fibers, moderate numbers of neuropeptide Y, somatostatin, and GRP fibers and rare enkephalin fibers. Nerve cell bodies reactive for each of the six neural peptides were located in both the myenteric and submucous plexuses. The ...

The purpose of this study was to determine whether morphologic and functional changes in intestinal smooth muscle occur after small bowel transplantation (SBTx) and during chronic rejection. Methods. Orthotopic SBTx was performed in syngeneic (ACI-ACI, n = 6) and allogeneic (ACI-Lewis, n = 6) rat strain combinations. The latter received temporary immunosuppression (cyclosporine 15 mg/kg/body weight on postoperative days 0 to 6 once a day, postoperative days 7 to 28 every other day), which led to clinically quiescent chronic rejection of the graft by 90 days after SBTx. At that time structure and function of the jejunal ...
TY - JOUR. T1 - Contractile properties of enteric smooth muscle after small bowel transplantation in rats. AU - Murr, Michel M.. AU - Miller, Virginia M. AU - Sarr, Michael G.. PY - 1996/1. Y1 - 1996/1. N2 - BACKGROUND: The effects of small bowel transplantation (SBTx) on the function of enteric smooth muscle are not understood. PURPOSE: To study the contractile properties of enteric smooth muscle after SBTx in rats. METHODS: Five groups of inbred Lewis rats (n ≥8 each group) were studied: unoperated, naive controls; operated controls 1 week (OC1) and 8 weeks after intestinal transection/reanastomosis of the proximal jejunum and distal ileum; and 1 week (TX1) and 8 weeks (TX8) after syngeneic orthotopic SBTx. Contractile activity of circular muscle strips of jejunum was evaluated in tissue chambers. Spontaneous contractile activity (force per wet weight tissue) increased in TX1, TX8, and OC1 rats (P ≤0.01). Frequency of contractions doubled in OC1 rats (P ≤0.001) but was unchanged in the ...

AU - Sonnino, R. E.. AU - Guttman, F. M.. PY - 1989/1/1. Y1 - 1989/1/1. N2 - Lewis, rats received syngeneic heterotopic grafts of jejunum immediately, or after preservation for 24 or 48 hours in Eurocollins solution. Most recipients of tissue stored for 0 or 24 hours remained healthy. Longer storage caused death of the recipients. We evaluated the effect of tissue preservation by comparing grafts stored for 0 and 24 hours with control jejunum at successive intervals up to ten days after transplantation. The physiology and pharmacology of smooth muscle and nerve endings were studied in vitro. Circular and longitudinal muscle in all specimens contracted in response to cholinergic agonists, phenylephrine, and substance P, and was relaxed by isoproterenol and noradrenaline. 5-hydroxytryptamine caused contraction ...
The small intestine in Chinese medicine has a very similar function to that of western medicine. The small intestines job is to receive food from the stomach and separate the clear from turbid. What this means is that the small intestine separates our food into usable energy (clear) and waste products (turbid). The clear energy goes back up to the spleen to be distributed throughout our entire body and the turbid energy goes down into the large intestine/urinary bladder (which in turn removes it). The small intestine in both Chinese and western medicine is the main digestive organ in our body.. The small intestine meridian is also called the Hand Tai Yang Meridian and its paired foot meridian is the Foot Tai Yang Meridian, or the urinary bladder. This shows a relationship between the small intestine and the output of waste of the urinary bladder. The small intestine has another deep relationship with the heart. The small intestines is a yang organ and its paired yin organ is the heart. This ...

N2 - Rejection remains a major obstacle to successful small bowel transplantation in humans, irrespective of the immunosuppressants. Previous large animal studies have not used quadruple immunosuppression (with high- dose intravenous cyclosporine A [CSA]) for induction, followed by triple immunosuppression for maintenance therapy. Nor have immunosuppressive doses been comparable to clinical solid organ transplants. We studied, in 78 nonrelated outbred pigs, the effect of quadruple immunosuppression (including horse anti-pig thymocyte globulin [ATG] and high-dose intravenous CSA) on the incidence and severity of rejection in the early, critical ...
Intestinal transplantation is being increasingly performed to treat patients with irreversible intestinal failure. The major cause of intestinal graft failure is graft-versus-host disease (GVHD) that represents a life-threatening complication after small bowel transplantation (Itx). The purpose of this study was to assess the diagnostic and prognostic value of skin biopsy histological changes for acute GVHD after Itx in pigs. Thirty-four Large White pigs were divided into three groups: Group I with Itx only, Group 2 with Itx and donor bone marrow infusion (Itx BM) and Group 3 (control group-before the operation). Animals received tacrolimus-based immunosuppression from day 0 to day 30 postoperatively. Skin and small bowel biopsies were histologically assessed, analysed and classified from grade I to 4 on postoperative days 15, 30, 45 and 60. There was a strong correlation between the histological grading values of skin biopsy changes and the histological grading values of small bowel biopsy ...
We present a detailed study of acute LPS-induced murine gut injury. Systemic LPS administration caused rapid IEC apoptosis and shedding in the murine small intestinal villus, and this resulted in shortening of the villus, fluid effusion into the small intestinal lumen and diarrhea.. We have characterized the dose response and kinetics of this highly dynamic phenomenon and demonstrate that it occurs within a tightly defined time period. All regions of the small intestine responded in a similar manner to LPS and in all cases apoptosis and cell shedding occurred in the apical 50% of the villus rather than exclusively at the tip. Using knockout mouse models, we confirmed that TLR4 signaling peripheral to the IEC was required, and that TNFR1-mediated signaling was essential for these events, with an NFκB2-dominant response favoring apoptosis.. Although there is an abundance of literature describing small intestinal crypt apoptosis several hours after the induction of endotoxic or septic shock (Cinel ...
In oncology, small intestine cancer, also small bowel cancer and cancer of the small bowel, is a cancer of the small intestine. It is relatively rare compared to other gastrointestinal malignancies such as gastric cancer (stomach cancer) and colorectal cancer.[citation needed] Small intestine cancer can be subdivided into duodenal cancer (the first part of the small intestine) and cancer of the jejunum and ileum (the later two parts of the small intestine). Duodenal cancer has more in common with stomach cancer, while cancer of the jejunum and ileum have more in common with colorectal cancer. Five year survival rates are 65%. Several different subtypes of small intestine cancer exist. These include: adenocarcinoma gastrointestinal stromal tumor lymphoma ileal carcinoid tumor Risk factors for small intestine cancer include: Crohns disease Celiac disease Radiation exposure Hereditary gastrointestinal cancer syndromes: familial adenomatous polyposis, hereditary nonpolyposis colorectal cancer, ...
TY - JOUR. T1 - Effect of Cholinergic Agonists on Muscle From Rodent Proximal and Distal Small Intestine. AU - Nowak, Thomas V.. AU - Harrington, Bonnie. PY - 1985/1/1. Y1 - 1985/1/1. N2 - Proximal and distal rat small intestine was cut into strips measuring 6.0 × 10.0 mm. Strips cut along the oral-caudal axis were called longitudinal strips, whereas those cut 90° to that axis were called circular strips. Stress in circular and longitudinal muscle strips was measured continuously as they were superf used with acetylcholine, carbamylcholine, methacholine, bethanechol, or physostigmine. Resting stress during stretch, acetylcholine-stimulated active stress, and total stress were determined. Proximal circular muscle was five times as sensitive to acetylcholine as distal circular muscle (p , 0.05); proximal longitudinal muscle was 2.8 times as sensitive to bethanechol as distal muscle (p , 0.05). Resting, active, and total stress were similar in proximal and distal muscle, but circular muscle ...
Quantifying the ability of a compound to modulate cell migration rate is a crucial part of many studies including those on chemotaxis, wound healing and cancer metastasis. Existing migration assays all have their strengths and weaknesses. The scratch assay is the most widely used because it seems appealingly simple and inexpensive. However, the scratch assay has some important limitations, as the tool introducing the wound might injure/stress the boundary cells and/or harm underlying matrix coatings, which in both cases will affect cell migration. This described method is a Cell Exclusion Zone Assay, in which cell-free areas are created by growing cells around removable silicone stoppers. Upon appropriate staining with fluorescent dyes and microscopically visualizing the monolayers, the migration rate is then quantified by counting the cells (nuclei) intruding the void area left by the silicone insert. In the current study human small intestine epithelial cells were seeded on a physiological ...
Purpose: Several urethral conditions may require tissue substitution. One collagen-base biomaterial that recently emerged as an option is small intestinal submucosa (SIS). The aim of this study was to compare the results of SIS and buccal mucosa for urethral substitution in rabbits.Materials and Methods: Thirty-six North Folk male rabbits were randomized into three groups. In all animals, a 10 x 5 mm urethral segment was excised, and the urethral defect was repaired using a one-layer SIS patch (group I [GI]); four-layer SIS (group II [GII]); or buccal mucosa (group III [GIII]). Urethrography was performed preoperatively and after 12 weeks. After sacrifice, graft retraction was objectively measured using Scion Image (R) computer analysis and by calculation of ellipse area. The grade of fibrosis, inflammatory reaction, vascular/epithelial regeneration, and collagen III/I ratio were analyzed by hematoxylin/eosin and Picrosirius red staining.Results: Urethrography confirmed a wide urethral caliber ...

Staging is the process that shows whether cancer has spread within or around the small intestine or to other parts of the body. Cancer spreads in the body in three ways: through tissue, the lymph system, or the blood.. Tests and procedures to stage small intestine cancer are usually done at the same time as diagnosis. Staging is usually done to find out how far the cancer has spread, but treatment decisions are not based on stage. Typically, the treatment depends on whether or not the tumor can be removed by surgery.. When cancer spreads from where it started to another part of the body, it is called metastasis. These metastatic cancer cells are the same type of cancer as the primary tumor. For example, if small intestine cancer spreads to the bone, the cancer cells in the bone are actually small intestine cancer cells. The disease is metastatic small intestine cancer, not bone cancer..

The small intestine, which is also called small bowel, is the section of the gastrointestinal tract that lies between the stomach and the large intestine. The small intestine makes up duodenum, jejunum, and ileum. Though it is called little intestine, it is in fact the largest part of the digestive tract. The length of the small intestine in adults is around 6 meters. Though the large intestine has to do with 1.5 meters long, it is called so due to its width. While the small intestine is around 2.5 to 3.5 cm wide, the diameter of the large intestine has to do with 10 cm. Small bowel performs vital functions including digestion of food and absorption of essential nutrients from the food into the body.

Ischemia reperfusion injury (IRI) is a major field of study in small bowel transplantation because of its implications regarding intestinal immunity. In this study, we have introduced some variations to the described models of IRI in pigs to make possible a complete isolation of the small bowel for IRI studies. In swine, two anatomical barriers make impossible a complete isolation of the small bowel at the origin of superior mesenteric artery (SMA) and vein (SMV): the main colic vessels, which originate distally to form SMA and SMV, and the blood supply of the distal portion of the duodenum and the cephalic part of the pancreas. In a group of Large White pigs (n = 5), we have performed a complete isolation of the small bowel, including sub-total colectomy and pancreaticoduodenectomy. Both SMA and SMV were isolated at the origin from the aorta and at the junction of the splenic vein, respectively. Intestinal continuity was restored with duodenojejunal anastomosis and with ileotransverse colon ...

How many miles of intestines does a human have? The KGB Agent answer: Not Medical Advice: The small intestine (small bowel) is about 20 feet long, while the large intestine (colon or large bowel) is about 5 feet long. They add up to 25 ft long or 0.00473485 mi. Our intestine is a muscular tube which extends from the lower end of your stomach to the lower opening of the digestive tract. It is also called the bowel or bowels. Food and the products of digestion pass through the intestine, which is divided into two sections called the small intestine and the large intestine. The small intestine is made up of three segments, which form a passage from your stomach (the opening between your stomach and small intestine is called the pylorus) to your large intestine: Duodenum Jejunum Ileum By the time food reaches your small intestine, it has already been broken up and mashed into liquid by your stomach. The large intestine is much broader than the small intestine and takes a much straighter path through

Small Bowel transplantation in rats is a highly complex microsurgical procedure because several technical complications may lead to recipient mortality and transplant failure. Our aim was to report the most common complications associated with orthotopic and heterotopic intestinal transplantation in rats in order to identify the pitfalls of the procedure and prevent them. A retrospective multicenter study was performed. All participant centers have established rodent transplant procedures and trained surgeons. Two hundred ninety-three complications from 264 unsuccessful intestinal transplants were reported, representing an overall failure rate of 15% of the procedures performed. Recipient complications were most frequent than donor (257 vs. 36 ...

TY - JOUR. T1 - HSP70 confers protection against indomethacin-induced lesions of the small intestine. AU - Asano, Teita. AU - Tanaka, Ken Ichiro. AU - Yamakawa, Naoki. AU - Adachi, Hiroaki. AU - Sobue, Gen. AU - Goto, Hidemi. AU - Takeuchi, Koji. AU - Mizushima, Tohru. PY - 2009/8. Y1 - 2009/8. N2 - In line with improvements in diagnostic procedures to detect intestinal lesions, it has become clear that nonsteroidal antiinflammatory drugs (NSAIDs) such as indomethacin induce lesions not only in the stomach but also in the small intestine. However, clinical protocols for the treatment of NSAID-induced lesions of the small intestine have not been established. It is known that heat shock proteins (HSPs), particularly HSP70, confer protection against various stressors, and more recently, the anti-inflammatory activity of HSP70 was revealed. In this study, we examined the effect of expression of HSP70 on indomethacin-induced lesions of the small intestine. The extent of indomethacin-induced lesions ...
[The effect of resection of the proximal small intestine on the inhibition of gastric secretion induced by gastrotsepin].: The removal of the proximal 1/3 part
With lactulose, there is greater ability to diagnose overgrowth in the distal end of the small intestine, which is thought to be most common. With the glucose challenge, absorption occurs faster so the test more accurately diagnoses proximal overgrowth, which is considered more specific to the bacteria of concern. While clinicians and researchers alike debate which method is superior for SIBO testing, we know that the patient is best served by doing both.. The large intestine (colon) has a quantity and variety of bacteria different from those of the small intestine.The small intestine houses approximately 10,000 bacteria per milliliter of fluid, as compared to the large intestine which houses approximately one trillion bacteria per milliliter of fluid. The primary function of the colonic bacteria is the fermentation of non-digestible carbohydrates, resulting in the formation of short chain fatty acids which stimulate epithelial growth and differentiation in the colonic epithelium.. The primary ...

The small intestine is the region between our stomach and large intestine or colon. It is important to learn more about what kind of bacteria communities that live in the small intestine where a lot of the digestion of food and glucose absorption take place. We also know that our immune system is affected by the conditions in our gut, and that much of the immunity that we develop is influenced by the bacteria living in the small intestine. Diseases such as inflammatory bowel syndrome, colitis, ulcers and obesity are associated with dysbiosis, a microbial imbalance in the gastrointestinal (GI) tract. The GI tract is the tract from the mouth to the anus including all organs of the digestive system.. Medical doctors call for more knowledge of our gut microbiota. And the small intestine is particularly difficult to sample. Researchers from the IDUN Center of Excellence at DTU Health Tech and colleagues from University of Copenhagen and the Danish Technological Institute have shown the first ...
Capillaries in intestinal villi. Light micrograph of a transverse section through villi in the small intestine, showing the blood supply. At bottom are the outer muscle layers in the wall of the small intestine. Villi are finger-like projections on the inner wall, which face the lumen (at top). The villi are adapted for the absorption of digested food. The core of each villus contains blood capillaries (dark), which here have been injected to highlight their structure. Epithelial cells on the surface of each villus absorb food, which is then passed into the bloodstream through this capillary system. The 6 metre long human small intestine contains thousands of villi. - Stock Image P520/0080
T cells expressing γδ T cell receptors (TCRs) represent a minority of circulating peripheral T cells, but certain epithelial sites, such as tongue, skin, reproductive tissue and intestine are enriched with γδ T cells. In the mouse, approximately 50% of the small intestinal intraepithelial lymphocytes (iIELs) express γδ TCRs. The majority of γδ iIELs express Vγ5 in association with Vδ4 or other Vδ genes. Vδ4 usage in different mouse strains has been shown to involve positive selection that maps to the MHC class II molecule I-E. In addition, positive selection mapping to the TCR γ locus has been demonstrated for splenic Vδ4+ T cells. Southern hybridization analyses provided evidence for the existence of two Vδ4 genes, one of which had been cloned (Vδ4.1). I have cloned and sequenced the second Vδ4 gene, Vδ4.2, from a mouse genomic DNA library. The sequence of the V region has 98% identity to Vδ4.1, with three conservative changes and three nonconservative changes. The Vδ4.2 gene
I havent reviewd this in a while. Take it with a grain of salt. Or sugar, hehe.. Hi again!. The digestive track: Mouth Esophogus Stomach Small intestine Large intestine. Nothing too new there, except for omissions due to my own ignorance, or enough ignorance to assume that the above may have omissions.. After the acid bath and pancreatic activity in the stomach, your food contents pass through the small intestine. The small intestine is for absorbing simple and fairly simple sugars. Glucose and fructose are mono-sacharides. The two together as sucrose is a disacharide. Those are supposed to be digested here in the small intestine. Or not really digested all that much, but mainly absorbed.. Free glucose is easily absorbed and countered by insulin in healthy subjects. Blood sugar regulation is strongly linked to metabolism. Hypo-glycemia is not far from hyper-glycemia, and is also related to tonicity of the blood, which is related to water, sugar, and mineral intake, and the bodies alterations of ...

2 The job of the small intestine is to remove nutrients from the chyme. Nutrients are all of the good things that your body needs. Protein, carbohydrates, fats, vitamins, and minerals are all nutrients. The nutrients move from your small intestine to your blood. It carries the nutrients to all the parts of your body. The inside of your small intestine is covered with millions of villi. Villi are like fingers that stick out from the surface of the small intestine. These villi are how your small intestine pulls nutrients out of the chyme. They form grooves and crevices for chyme to flow into. This makes the surface area of the small intestine much larger than it looks. That means that the small intestine can pull out many more nutrients than it could with a smooth surface ...

Small intestinal cancer is also alluded to as small bowel cancer which is represented as the tumors improvement which is responsible for the development of the cancerous cells that happen in specific regions of small intestine. Small intestine cancer is an uncommon disease in which malignant (cancer) cells structure in the smalls tissues intestine. In certain cases, this kind of cancer shows specific resemblances with the arrangement of malignant tumor that takes place in the gastrointestinal synthesis & this belongs to the categories of stomach cancer, colorectal cancer and so forth. These must not be left untreated & in the event that they are overlooked, they possess the potential capacity to increase appallingly in size & thus make their unsafe effect on alternate organs of the human body.. The cancer, which takes place in the small intestine, is sorted in three categories, which are in particular duodenal cancer, jejunum cancer & ileum cancer. These are further classified into the types ...

Your intestines are 6.5 metres long. Thats nearly as long as a double decker bus!. Measure and cut a piece of string thats 6.5 metres long. Will the string stretch all the way around your bed? Will it stretch across one of the rooms in your house?. Your intestines are made up of the small intestine and large intestine.. After food is churned up in your stomach, a muscle at the end of your stomach squirts small amounts of food into the top of your small intestine.. As food is squeezed along the small intestine, it is broken down into even smaller parts. Most of the nutrients in your food pass through the lining of your small intestine into your blood.. Anything that cant be absorbed into the blood goes into the large intestine. Water is reabsorbed in the large intestine...everything else comes out as poo!. Want to know more about poo? Go to Ew, poo!. ...
The small intestine is found in all tetrapods and also in teleosts, although its form and length vary enormously between species. In teleosts, it is relatively short, typically around one and a half times the length of the fishs body. It commonly has a number of pyloric caeca, small pouch-like structures along its length that help to increase the overall surface area of the organ for digesting food. There is no ileocaecal valve in teleosts, with the boundary between the small intestine and the rectum being marked only by the end of the digestive epitheliu [18]. In tetrapods, the ileocaecal valve is always present, opening into the colon. The length of the small intestine is typically longer in tetrapods than in teleosts, but is especially so in herbivores, as well as in mammals and birds, which have a higher metabolic rate than amphibians or reptiles. The lining of the small intestine includes microscopic folds to increase its surface area in all vertebrates, but only in mammals do these ...

The method of EDTA-mediated elution of human enterocytes, applied in these studies to the human small intestine for the first time, offers advantages over mechanical scraping of the mucosa (Paine et al., 1997); villous and crypt cells can be separated for investigation individually and the more gentle nature of the isolation procedure is less likely to damage the cells. Human and rat (Fasco et al., 1993) villous enterocytes exhibited similar susceptibility to release and elution from the small intestine by EDTA. However, in contrast to the rat small intestine where 1.5 mM EDTA effectively removes crypt cells after an extended period of incubation, 5.0 mM EDTA only removed up to 10% of crypt cells from human small intestine after a similar incubation period. A separation of human villous and crypt cells can thus be achieved by first eluting the villous cells with EDTA and then releasing the residual crypt cells mechanically by scraping.. The current studies support the well established ...
