The effect of fat supplementation of high calcium (Ca) diets on the performance, intestinal pH, body composition and size and weight of organs in growing chickens were investigated in two experiments. Growing chickens tolerated a high dietary level of Ca (22.5 vs 12.1 g/kg) in the presence of 6.3 g/kg of available phosphorus without any significant effect on performance. Intestinal pH was significantly increased by the addition of excess Ca and fat which probably created the right pH for the formation of insoluble Ca soaps. Excess dietary Ca increased carcass linoleic acid concentration at the expense of palmitic and stearic acid contents, whilst the addition of sunflower oil (80 g/kg diet) to the diet increased carcass linoleic acid concentration at the expense of palmitic acid content of the carcass. Intestinal and visceral organ size and weight were not influenced by excess Ca or fat. However, there was a non significant increase in the intestinal dry weight per unit of length caused by excess dietary Ca. It was concluded that excess dietary Ca of 22.5 g/kg did not significantly influence the performance of meat chickens. However, excess Ca increased intestinal pH and altered carcass fatty acid composition. Fat supplementation did not alter intestinal pH with high Ca diets. Excess dietary fat altered carcass fatty acid composition and reduced protein content. Intestinal and visceral organ size and weights were not influenced by excess dietary levels of Ca of fat.

Diseases in the gastro-intestinal tract are on an increasing trend. In order to diagnose a patient, various signals of the digestive organ, such as temperature, pH, and pressure, can offer the helpful information. Among the above mentioned signals, we choose the pressure variation as a monitoring signal. The variation of a pressure signal of the gastro-intestinal tract can offer the information of a digestive trouble or some clues of the diseases. In this paper, a pressure monitoring system for the digestive organs of a living pig is presented. This is why a pig's gastro-intestinal tract is very similar as human's. This system concept is to transmit the measured biomedical signals from a transmitter in a living pig to a wireless receiver that is positioned out of body. The integrated solution includes the swallow type pressure capsule and the receiving set consisting of a receiver, decoder circuit. The merit of the proposed system is that the monitoring system can supply the precise and a durable characteristic to measure and to transmit a signal in the gastro-intestinal tract. We achieved the pressure tracings in digestive organs and verified the validity of system after several in-vivo tests using the pressure monitoring system. Through various experiments, we found each organ has its own characterized pressure fluctuation.

In this paper, a pressure monitoring system for the digestive organs of a living pig is presented. This system concept is to transmit the measured biomedical signals from a transmitter in a living pig to wireless receiver that is positioned out of body. The integrated solution includes the following parts: (1) the swallow type pressure capsule, (2) the receiving set consisting of a receiver, decoder box, and PC. The merit of the proposed system if that the monitoring system can supply the precise and repeatable pressure in the gastro-intestinal track. In addition, the design of low power consumption enables it to keep sending reliable signals while the pressure capsule is working in the digestive organ. The subject of the study for the pressure monitoring system is in-vivo experiments for a living pig. We achieved the pressure tracings in digestive organs and verified the validity of system after several in-vivo tests using pressure monitoring system. As a result, we found each organ has its own characterized pressure fluctuation.

Paraneoplastic hypereosinophilia, characterized by the infiltration of eosinophils into systemic organs, has rarely been reported in dogs with intestinal lymphoma. A 12-year-old spayed female Maltese with eosinophilia in the peripheral blood and ascites was found to have muscular layer thickening in the small intestine. Histologically, there was transmural infiltration of small to intermediate sized neoplastic lymphocytes that were immunohistochemically CD3-/CD79a-. PCR for antigen receptor rearrangement demonstrated clonal T cell receptor gene population. A moderate number of eosinophils were present along with neoplastic lymphocytes in the small intestine, and eosinophil infiltration was also noted in the abdominal lymph nodes and spleen. The present case reports intestinal T-cell lymphoma with generalized paraneoplastic hypereosinophilia. Clinicians should be aware that hypereosinophilia can be found in the organs, body cavity fluid, and peripheral blood of dogs with intestinal lymphoma.

The phytase(myo-inositol hexkisphosphate phosphohydrolase ; EC 3.1.3.8) activity was observed only in the homogenate of intestinal mucosa, though the activity of alkaline phisphatase was measurable in various organs. In addition, no protein bands were detected in any other organs on immunoblotting using the anti-90kDa phytase antiserum. Thses results suggest that phytase is specifically present in small intestinal mucosa, and that hydrolysis of phytic acid(inositol-hexakisphosphate) can be allotted for a physiological role of the intestine-specific enzyme. The activities of phytase was increased during development of rat. The 70kDa phytase appeared just after birth, but the 90kDa phytase was not observed until adult period, suggesting that the 90kDa phytase was synthesized in response to weanling.

Ovariectomy induced hyperphagia was reported in various animal models. It was postulated that hyperphagia resulted in interstinal hypertrophy and hyperplasia. Therefore, this study was performed to compare the food intake and intestinal changes between ovariectomized rats(OVX) and sham operated rats(Sham). Results of this study showed that the food intake and body weight of OVX animal was significantly higher than those of Sham animal. This results confirmed the effect of ovarian hormone on the food intake regulation. Hyperphagia induced by ovariectomy influence the intestinal cell growth and showed hyperplasia determined by protein/DNA ratio. Maltase and alkaline phosphatase activity suggested that the intestinal cell was fully matured in body groups. There were no difference in weight of other organs, such as liver, heart and kindney between two groups.

Objective: Intestinal alkaline phosphatase (IAP) maintains intestinal homeostasis by detoxifying bacterial endotoxins and regulating gut microbiota, and lipid absorption. Antibiotics administered to animals can cause gut dysbiosis and barrier disruption affecting animal health. Therefore, the present study sought to investigate the role of IAP in the intestinal environment in dysbiosis. Methods: Young male mice aged 9 weeks were administered a high dose of antibiotics to induce dysbiosis. They were then sacrificed after 4 weeks to collect the serum and intestinal organs. The IAP activity in the ileum and the level of cytokines in the serum samples were measured. Quantitative real-time polymerase chain reaction analysis of RNA from the intestinal samples was performed using primers for tight junction proteins (TJPs) and proinflammatory cytokines. The relative intensity of IAP and toll-like receptor 4 (TLR4) in intestinal samples was evaluated by western blotting. Results: The IAP activity was significantly lower in the ileum samples of the dysbiosis-induced group compared to the control. The interleukin-1 beta, interleukin-6, and tumor necrosis factor-alpha concentrations were significantly higher in the ileum samples of the dysbiosis-induced group. The RNA expression levels of TJP2, claudin-3, and claudin-11 showed significantly lower values in the intestinal samples from the dysbiosis-induced mice. Results from western blotting revealed that the intensity of IAP expression was significantly lower in the ileum samples of the dysbiosis-induced group, while the intensity of TLR4 expression was significantly higher compared to that of the control group without dysbiosis. Conclusion: The IAP activity and relative mRNA expression of the TJPs decreased, while the levels of proinflammatory cytokines increased, which can affect intestinal integrity and the function of the intestinal epithelial cells. This suggests that IAP is involved in mediating the intestinal environment in dysbiosis induced by antibiotics and is an enzyme that can potentially be used to maintain the intestinal environment in animal health care.

Although small bowel the mainly occupies the most part of the gastrointestinal tract, small intestine tumors are rare, insidious in clinical presentation, and frequently represent a diagnostic and management challenge. Small bowel tumors are generally classified as epithelial, mesenchymal, lymphoproliferative, or metastatic. Familial adenomatous polyposis and Peutz-Jeghers syndrome are the most common inherited intestinal polyposis syndromes. Until the advent of capsule endoscopy (CE) and device-assisted enteroscopy (DAE) coupled with the advances in radiology, physicians had limited diagnostic examination for small bowel examination. CE and new radiologic imaging techniques have made it easier to detect small bowel tumors. DAE allows more diagnosis and deeper reach in small intestine. CT enteroclysis/CT enterography (CTE) provides information about adjacent organs as well as pictures of the intestinal lumen side. Compared to CTE, Magnetic resonance enteroclysis/enterography provides the advantage of soft tissue contrast and multiplane imaging without radiation exposure. Treatment and prognosis are tailored to each histological subtype of tumors.

Pelvic inflammatory disease (PID) is a general term that refers to infection of the internal reproductive organs such as the female uterus, fallopian tubes, and ovaries. PID is caused by germs that invade the genital organs, causing the acute inflammatory reaction, and chronic PID is to have a recurrence of PID because of the lack of effective treatment of acute PID. Symptoms of PID include pelvic pain, fever, leukorrhea, infertility, and fatigue. Treatments for PID can be improved by combining herb medicine therapy, intestinal irrigation, or the therapy that put herb medicine on the abdominal region with antibiotics, or analgesic drugs.
