A seven-month pregnant 15-year-old Thoroughbred mare presented with acute abdominal pain to Jeju National University Equine Hospital. At presentation, a nasogastric intubation revealed 10 L of gastric reflux; rectal palpation and ultrasound revealed dilated loops and thickening of the walls of the small intestine. An exploratory laparotomy revealed strangulation of the small intestine due to a large abdominal mass. The mass was double-ligated and resected blindly due to the short pedicle. An enterectomy was not performed as intestinal motility was detected following the mass removal. Histopathological examination confirmed that the mass was a lipoma, measuring 24 cm × 16 cm × 16 cm in size. On day 8 post-surgery, the mare was discharged without complications. This case report describes the diagnosis and treatment of strangulation of the small intestine by a pedunculated lipoma, thus providing useful information on lipoma in horses.

The objective of this experiment was to investigate the development of gastrointestinal tract and activities of pancreatic enzymes in White Roman geese. Thirty developing embryos at the 22th, 24th and 26th day of incubation and at hatching, and sixteen or eight goslings, half males and half females, at the 1, 3, 7 or 11, 14, 21 and 28 days of age were sampled, respectively. The weights of the yolk, gastrointestinal tract and intestinal length, and the activities of pancreatic enzymes were measured. Residual yolk weight decreased rapidly during late incubation and was nearly depleted at 3 days of age. The protein and energy contents in the residual yolk of goslings at 3 days of age were significantly (p<0.05) less than those at the late incubation. From 6 days before hatching to 28 days of age, the absolute weights of gizzard, proventriculus, liver, pancreas, small intestine and large intestine in goslings increased by 48, 457, 94, 2334, 89 and 76 times, respectively. The relative weights of proventriculus, gizzard, liver, pancreas, small intestine and large intestine reached peaks at 3, 3, 14, 14, 11 and 11 days of age, respectively, and then decreased gradually. However, the relative lengths of small intestine and large intestine reached peaks at 3 days of age and at hatching, respectively. The activities of pancreatic trypsin and chymotrypsin increased sharply from hatching to 14 day of age, and then decreased gradually until 21 days of age. The activity and specific activity of pancreatic amylase were increased following by age and peaked at 7 to 11 and 21 days of age, respectively. The activity and specific activity of pancreatic lipase reached a plateau from 11 to 28 days of age. These results indicate that the gastrointestinal tract and activities of pancreatic enzymes developed more rapidly than body weight through the early growing period of goslings.

The purpose of this stady was to investigate division cells by in vivo bromodeoxyuridine(Brdur) immunohistochemistry for labeling the proliferative epithelial cells in the gastrointestinal tracts of rats. Rats were administrated intraperitonially by twice consecutive injections of 24 hr interval with Brdur(0.05mg/g BW/time) and then were sacrificied at 1 hour after last injection. The specimens were taken from the stomach, small intestine(ileum), and large intestine(colon). The well-oriented crypts and villi in the preparations were examined, The crypt columns and villi were devided into 10 segments from crypt base to surface of the lumen or to villis top. Labeling index(LI) was measured by counting the number of Brdur-positive cells against the total number of crypt column cells in the stomach and large intestine and also against the total numbers of crypt column and it's villi epiterial cells in the small intestine. 1. In the stomach, the LI in each part from segment 1 to segment 10 of the crypt column were 4.2%, 5.0%. 6.6%, 9.0%, 11.3%, 15.3%, 9.3%, 15.6%, 11.3%, 0%, respectively and it's mean LI were 8.7%. The Brdur-positive epithelial cells were predominantly located in the middle regions and middle-upper regions of the crypt columns. 2. In the small intestine, the LI in each part from segment 1 to segment 10 of were 62.4%, 50.9%, 27.8%, 22.5%, 18.6%, 12.1%, 7.5%, 4.3%, 2.5%, 1.4%, respectively and it's mean LI were 21.0%. The Brdur-positive epithelial cells were predominantly located in the lower regions of the crypt columns and tended to be less in the higher regions of the villi than that in the crypt column. 3. In the large intestine, the LI in each part from segment 1 to segment 10 of the crypt column were 19.4%, 29.9%, 34.1%, 41.6%, 41.2%, 32.4%, 25.4%, 15.4%, 10.8%, 1.2%, respectively and it's mean LI were 25.1%, The Brdur-positive epithelial cells were predominantly in the middle and middle-lower regions of the crypt columns. 4. The organs with higher LI were ordered as the large intestine(25.1%), small intestine(21.0%) and stomach(8.7%).

The writer reports the conclusions gained from study about the cause of the hypersensitive large intestine syndrome with Dongeuibogam as the central figure through researching the disharmony among Body Essence, Vital Energy, Mentality, and Blood, mutual action of five viscera and six bowels, and external shapes. The hypersensitive large intestine syndrome is generally chronic and recurred in many cases, so it is more efficacious than symptomatic to treat according to find the contradictions of individual shapes. The shapes and cases suffering frequently the hypersensitive large intestine syndrome are Gi-kwa and Sin-kwa, having a long nose, having a bruised spot on Triple warmer, man with inclined mouth, Taeeum type, man with congested fluids, man with colic symptoms. The hypersensitive large intestine syndrome in Oriental medicine is recognized of diarrhea, constipation, abdominal pain, abdominal distention and fullness caused by seven emotions. In Dongeuibogam it can be found out the similarity in depressive symptoms due to disorder of Gi, stagnation of Gi, dysphasia due to disorder of Gi, diarrhea due to disorder of Gi, fullness of due to Gi, diarrhea due to phlegm-retention, retention of undigested food, immoderate drinking, hypo-function of the spleen, or deficiency, abdominal pain from colic symptom, and difficulty in defecation and urination, internal injury, diarrhea due to weakness and fatigue. If the Jung, Gi, Sin, and Hyul composed the human body is broken harmony, the function of large intestinal transmission would be fallen, so similar symptoms like the hypersensitive large intestine syndrome are gotten. Especially Gi-kwa suffers diarrhea, constipation abdominal pain, and abdominal distention and fullness due to depressive symptoms from disorder of Seven emotions or Seven Gi. And Sin-kwa suffers from the hypersensitive large intestine syndrome due to emotional restlessness having an influence on rhythmic movement of abdomen. Examining between five viscera and six bowels and the hypersensitive large intestine syndrome, Liver cannot disperse well having influence on mutual relation of Liver-Large intestine, Heart reduces the function of defecation and urination not to control the seven emotions, Lung having exterior and interior relation with intestine has an influence on primordial energy and let the main symptoms occur, Spleen circulating the body fluid let the main symptoms occur due to malfunction of circulation, Kidney locating in lower part of the body has deep connection with intestine, so let the disorder. Urinary bladder is connected with intestine in moisture metabolism, Stomach is connected in receive and transmission, Small intestine is connected in absorption and excretion, from small intestine pain disturbing the abdominal movement, Samcho managing the catharsis of lower heater if declined its function causes the hypersensitive large intestine syndrome. The colic symptoms of Front private parts which disorder in lower abdomen give rise to abdominal pains, difficulty in defecation and urination due to Cold are similar to the hypersensitive large intestine syndrome. The treatments of applying the shapes of colic syndrome advocated by Master Park can be efficacious cure in clinic. Researching after the clinical cases of Master Park advocating Hyungsang medicine, we came to know that plenty of prescriptions of internal injury are applied and take good effects.

The distribution channel of meat by-products from the pig farm to the final consumer can include a meat processor, wholesale market, wholesaler, retailer, and butcher shop. Bacterial contamination at any of these steps remains to be a serious public health concern. The aim of this study was to evaluate the distribution channel and microbial characteristics of pig by-products in Korea. Upon evaluation of pig by-products in cold storage, we found that the small and large intestine were significantly (p<0.05) higher in pH value compared to the heart and liver. The total plate counts were not significantly different among offals until cold storage for 7 d. The coliform count after 1 d of cold storage was significantly (p<0.05) higher in small and large intestine than in the other organs. The coliform count of heart, liver, and stomach showed a higher coliform count than small and large intestine until 7 d of cold storage. As determined by 16S rRNA sequencing, contamination of major pig by-products with Escherichia coli, Shigella spp., and other bacterial species occurred. Therefore, our results suggest that a more careful washing process is needed to maintain quality and hygiene and to ensure the safety of pig by-products, especially for small and large intestine.

Background: Gut microflora contributes to the nutritional metabolism of the host and to strengthen its immune system. However, if the intestinal barrier function of the living body is destroyed by radiation exposure, the intestinal bacteria harm the health of the host and cause sepsis. Therefore, this study aims to trace short-term radiation-induced changes in the mouse gut microflora-dominant bacterial genus, and analyze the degree of intestinal epithelial damage. Materials and Methods: Mice were irradiated with 0, 2, 4, 8 Gy X-rays, and the gut microflora and intestinal epithelial changes were analyzed 72 hours later. Five representative genera of Actinobacteria, Firmicutes, and Bacteroidetes were analyzed in fecal samples, and the intestine was pathologically analyzed by Hematoxylin-Eosin and Alcian blue staining. In addition, DNA fragmentation was evaluated by the TdT-mediated dUTP nick-end labeling (TUNEL) assay. Results and Discussion: The small intestine showed shortened villi and reduced number of goblet cells upon 8 Gy irradiation. The large intestine epithelium showed no significant morphological changes, but the number of goblet cells were reduced in a radiation dose-dependent manner. Moreover, the small intestinal epithelium of 8 Gy-irradiated mice showed significant DNA damaged, whereas the large intestine epithelium was damaged in a dose-dependent manner. Overall, the large intestine epithelium showed less recovery potential upon radiation exposure than the small intestinal epithelium. Analysis of the intestinal flora revealed fluctuations in lactic acid bacteria excretion after irradiation regardless of the morphological changes of intestinal epithelium. Altogether, it became clear that radiation exposure could cause an immediate change of their excretion. Conclusion: This study revealed changes in the intestinal epithelium and intestinal microbiota that may pave the way for the identification of novel biomarkers of radiation-induced gastrointestinal disorders and develop new therapeutic strategies to treat patients with acute radiation syndrome.

This study was conducted to develop an effective heparin extraction method by using low-cost and highly effective enzymes from six pig by-products (liver, lung, heart, stomach, small intestine, and large intestine), and analyze their bioavailability. Low-cost and highly effective enzymes (alkaline-AK and papain) and a common enzyme (trypsin) were used for the heparin extraction. The angiotensin I- converting enzyme (ACE) inhibitory activity and the antimicrobial activity of extracted heparin were analyzed to verify their bioavailability. The average amount of heparin extracted per kilogram of pig by-products was 439 mg from the liver, 127 mg from the lung, 398 mg from the heart, 261 mg from the stomach, 197 mg from the small intestine, and 239 mg from the large intestine. Various enzymes were used to extract heparin, and the amount of extracted heparin was similar. Based on 1 g of pig by-product, the enzymes trypsin, papain, and alkaline-AK could extract 1,718 mg, 1,697 mg, and 1,905 mg of heparin, respectively. Heparin extracted from pig by-products showed antihypertensive activity and antimicrobial activity against Staphylococcus aureus at low populations. These results indicated that heparin can be obtained from pig by-products at a low cost.

Regional distribution and relative frequency of endocrine cells in ten portions of the gastrointestinal tract of the Korean native cattle were observed by immunocytochemical methods using specific antisera against chromogranin, serotonin, somatostatin, glucagon, bovine pancreatic polypeptide(BPP), motilin, gastric inhibitory polypeptide(GIP), neurotensin, secretin, gastrin and substance P. The results observed are summarized as follows: In the abomasum, chromogranin-, serotonin-, somatostatin-, motilin-, glucagon-, gastrin-, and substance P-immunoreactive cells were found. Chromogranin-and serotonin-immunoreactive cells were more numerous in the fundic region than pyloric region. Somatostatin- and gastrinimmunoreactive cells were numerous in the pyloric region than in the fundic region. In the small intestine, chromogranin-, serotonin-, somatostatin-, glucagon-, BPP-, motilin-, gastrin-, GIP-, neurotensin-, secretin-, and substance P-immunoreactive cells were detected. Chromogranin-, somatostatin-, GIP- and secretin-immunoreactive cells were most numerous in the duodenum, while BPP-, motilin-, glucagon-, neurotensin- and substance P-immunoreactive cells were rarely seen in the small intestine. In the large intestine, chromogranin-, serotonin- and BPP-immunoreactive cells were widely distributed and most numerous in the rectum. Somatostatin-, glucagon- and substance P-immunoreactive cells were rarely seen in the large intestine.

The purpose of this study was to develop a commercially viable method for synthesis of conjugated linoleic acid (CLA) using the linoleic acid fraction obtained from six pork by-products (liver, lung, heart, stomach, small intestine, and large intestine). The workflow of CLA synthesis from each by-product was as follows: washing${\rightarrow}$crude fat extraction${\rightarrow}$fractionation into saturated and unsaturated fatty acids${\rightarrow}$repeat unsaturated fatty acid fractionation${\rightarrow}$CLA synthesis. Cis-9, trans-11, and trans-10, cis-12 CLA was synthesized from pork by-products. The yield of CLA synthesis of pork by-products ranged from 1.55 to 11.18 g per 100 g of by-products. The amount of synthesized CLA was the highest in the small intestine and large intestine by-products. Fractionation of pork by-products nearly doubled the yield of CLA. We suggest that commercial fractionation methods could increase the yield of CLA at low cost, reduce waste, and improve the efficiency of by-product utilization.
