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 ...

TY - JOUR. T1 - Small bowel transplantation and chronic rejection alter rat intestinal smooth muscle structure and function. AU - Heeckt, P. F.. AU - Halfter, W. M.. AU - Schraut, W. H.. AU - Lee, K. K W. AU - Bauer, A. J.. AU - Harken, A. H.. AU - Thompson, J. S.. AU - Flye, M. W.. AU - Sarr, M. G.. AU - Schirmer, B. D.. AU - Brolin, R. E.. PY - 1993. Y1 - 1993. N2 - Background. 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 ...

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 ...
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 ...

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. There are a number of diseases that can affect the function of the small bowel in an unfavorable manner ...
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

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 ...

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 ...

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 ...

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.[22] 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 develop ...

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 ...

In the event that clinical signs and laboratory tests indicate probable malabsorption, a biopsy of the small intestine [jejunal] is called for. In this test, a small flexible biopsy instrument is passed through a tube, down the throat, through the stomach and into the upper end of the small intestine where patchy, multiple snippets of tissue are gathered. The tube is removed and the tissue samples are examined under a microscope for signs of injury.. The difference between tissue in a normal small intestine and that found in a celiac patient is remarkable. The normal finger-like projections (villi), which increase the absorptive surface area of the small intestine, are partially or totally flattened in a person with celiac disease. Enzymes located on the brush border are also drastically reduced. Lactase, the enzyme responsible for splitting milk sugar (lactose) so it can be absorbed, is an example of one of these brush border enzymes. This decrease in lactase explains why some untreated celiac ...
Abstract: Mitochondria from mucosa of rat small intestine were separated (0-11% gradient of ficoll) into fractions, differing by the content of protein, DNA and cytochrome a+a3 as well as by the respiratory activity and the activity of succinate- and NADH-dehydrogenases. Content of DNA and cytochrome a+c was shown to be increased in heavy mitochondrial fractions. Mitochondria od midle fractions possessed the highest functional activity. The data obtained suggest that the mitochondrial preparations are not contaminated by other cytoplasmic structures; they were also not impaired during isolation and fractionation. The activity of RNA and DNA synthesis in vivo and distribution of labelled mitochondrial RNA and DNA in the fractions were studied. The possible relation of mitochondrial heterogeneity to, their biogenesis is discussed ...
Introduction:The small intestinal submucosa (SIS), a source of allogenic and xenogenic extracellular matrix (ECM), had been playing an increasing role in many biomedical applications. However, there has been little research on how specific interactions between cells and the SIS influence cell protection and repair. In this work, assays of cell viability, function, apoptosis, and migration were used to evaluate the ability of SIS to protect and repair osteoblastic MC3T3-E1 cells from hormone-induced stress damage. Materials & Methods:SIS extracts were prepared with α-MEM basal medium according to ISO10993-12:2007 at the ratio of 3 cm2/mL after incubation for 24 h at 37°C. Cell damage was induced by the addition of dexamethasone (10− 9-10− 5 M for 24 h) to the culture medium, while SIS extracts were added before, along with, or after the dexamethasone treatment. Results & Discussion :Higher concentrations of dexamethasone (10− 7-10− 5 M) caused a reduction in cell viability, cell function, and
Antibiotics have been the primary cause, but non-steroidal anti-inflammatory drugs (NSAIDs) are a major secondary cause. Antibiotics also damage the intestines by fostering the growth of Candida albicans and other pathogenic fungi and yeast. This overgrowth of yeast, more than any other factor, precipitates leaky gut syndrome. In a healthy situation, the small intestine epithelium maintains tight cell junctions, which contributes to the physical barrier involved in intestinal absorption. In addition to the physical barrier, there is an important chemical barrier within the mucus that contains immune agents which neutralize any toxins that come in contact with the intestinal lining. Candida exudes an aldehyde secretion that causes small intestine epithelial cells to shrink. This allows intestinal toxins to infiltrate through the epithelium and into the blood. The secondary barrier-immune agents in the epithelial mucus-remain the sole agent for neutralization. Eventually, the immune system becomes ...
