Two Domestic Korean Shorthair cats presented with dyschezia and vomiting. Computed tomography revealed a colonic mass with calcification and lymph node metastasis in case 1, and a small intestinal mass with disseminated mesenteric metastasis and calcification in case 2. Histopathology revealed intestinal adenocarcinoma with osseous metaplasia. Case 1 died two months after surgery from distant metastasis; and case 2 showed no metastasis for five months but presented with anorexia, euthanized seven months after diagnosis. Metastatic intestinal adenocarcinoma with bone formation should be considered as differential diagnosis for calcification on imaging, and lymph node metastasis at diagnosis may indicate poor prognosis.

Gastric adenocarcinoma (GA) is a major tumor type of gastric cancers and subdivides into several different tumors such as papillary, tubular mucinous, signet-ring cell and adenosquamous carcinoma according to histopatholigical determination. In other hand, GA is also subdivided into intestinal and diffuse type of adenocarcinoma by the Lauren?fs classification. In this study, we have examined differential gene expression pattern analysis of three histologically different GAs of 24 samples by using DNA microarray containing approximately 19000 genetic elements. The hierarchical clustering analysis of 24 gastric adenocarcinomas (12 of intestinal type, 7 of diffuse type and 5 of mixed type) resulted in two major subgroup on dendrogram, and two subgroups included most of intestinal and diffused type of GAs respectively. Supervised analysis of 19 intestinal and diffuse type GAs by using Wilcoxon rank T-test (P<0.01) resulted in 100 outlier genes which exactly separated intestinal and diffuse type of GA by differential gene expression. In conclusion, genome-wide analysis of gene expression of GAs suggested that GAs may subclassify as intestinal and diffused type of GA by their characteristic molecular expression. Our results also provide large-scale genetic elements which reflect molecular differences of intestinal and diffuse type of GAs, and this may facilitate to understand different molecular carcinogenesis of gastric cancer.

Five years old Asian male elephant (Elephas maximus), transported from Malaysia, had showed slight inappetence and mild diarrhea from begining of stay at the zoo, and died after three months clinical therapy. Necropsy of this elephant grossly demonstrated ileocecal intussusception as the cause of the death, coupled with purulent nephritis together and nephrolithiasis, mild liver degeneration, numerous subepiacrdial and subendocardial hemorrhages. Bacteriological culture was conducted from renal pelvis revealing Klebsiella pneumonia infection. Histological findings included diffuse chronic interstitial nephritis with numerous amount of lymphocytes and giant cells. This is a unique combination of pathological findings consisting of intestinal intussusception and purulent pyelonephritis in elephant. This is the first description of intestinal intussusception together with severe nephritis in elephant

This study was examined the effects of Daesenggi-Tang on intestinal mucosa and gastrointestinal transit time and plasma lipids in rats. Adult male rats were fed four weeks on diets containing no addition(basal diet group), 5% cellulose(cellulose group) and Daesenggi-Tang group(Daesenggi-Tang group). The results were as follows; 1. The gastrointestinal transit times was significantly decreased in Daesenggi-Tang administered group compare to basal diet and cellulose groups. Carmine red mixed with Daesenggi-Tang, as a marker, was administered through a gastric tube for stomach or intracecally by a chronically implanted catheter for colon transit. Small intestinal transit and large intestinal transit time were significantly decreased in Daesenggi-Tang administered group compare to basal diet. 3. The height of jejunal villi was developed in Daesenggi-Tang administered group compare to basal diet. The thickness of mucosa and muscle layer of colonic mucosa were significantly developed in Daesenggi-Tang administered group compare to basal diet group. 4. The numerical change of goblet cell in colonic mucosa was increased acid mucin stained alcian blue in Daesenggi-Tang administered group compare to basal diet and cellulose group. 6. HDL-cholesterol of plasma lipid was increased in Daesenggi-Tang administered group compare to basal diet and cellulose groups. Theses results suggests that Daesenggi-Tang may be used in prevention and treatment of constipation resulting in increase of fecal weight, decrease of gastrointestinal transit time, development of intestinal villi, intensify of stainability of acid mucin in colon.

T-lymphocytic intestinal leiomyositis is a rare cause of "pediatric intestinal pseudo-obstructions." Diagnosis may be difficult and requires full-thickness bowel biopsies during laparotomy or laparoscopy with possible enterostomy. Currently, immunosuppressive therapy is the only available treatment. A delay in diagnosis and therapy may negatively affect the prognosis because of ongoing fibrotic alterations; therefore, early diagnosis and consequent treatment are crucial. This review summarizes the available information on the nosology, diagnostic steps, and treatment modalities. Here, we report the youngest case of enteric leiomyositis reported in the last two decades and analyze its management by reviewing previous cases.

A clinical suspicion of intestinal spirochetosis is required when patients have long lasting complaints of abdominal pain, diarrhea, rectal bleeding, weight loss, and nausea. An endoscopy with biopsies needs to be performed to confirm the diagnosis of intestinal spirochetosis. The diagnosis of intestinal spirochetosis is based on histological appearance. Intestinal spirochetosis can also be associated with other intestinal infections and juvenile polyps (JPs). JPs seem to be more frequent in patients with intestinal spirochetosis than in patients without intestinal spirochetosis. Intestinal spirochetosis in children should be treated with antibiotics. Metronidazole is the preferred option. In this article, we describe 4 cases of intestinal spirochetosis in a pediatric population and provide a review of the literature over the last 20 years. Intestinal spirochetosis is a rare infection that can cause a variety of severe symptom. It is diagnosed based on histological appearance.

Constipation is a common clinical problem that comprises of symptoms that include excessive straining, hard feces, feeling of incomplete evacuation and infrequent defecation. Although many conditions, such as metabolic problems, fiber deficiency, anorectal problem, an drug, can cause constipation. This study was examined the effects of Chilsun-Whan on intestinal mucosa and gastrointestinal transit time and plasma lipids in rats. Adult male rats were fed for weeks on diets containing no addition(basal diet group), 5% cellulose(cellulose group) and 2.5% . Chilsun-Whan group(Chilsun-Whan group). The results were as follows; 1. The fecal weght was significantly increased 2 times in Chilsun-Whan administrated group compare to basal diet group. 2. The gastrointestinal transit times was significantly decreased in Chilsun-Whan administrated group compare to basal diet. 3. Carmine red mixed with Chilsun-Whan, as a marker, was administered through a gastric tube for stomach or intracecally by a chronically implanted catheter for colon transit.

In order to rapidly identify and differentiate Salmonella typhimurium from the intestinal gram-negative bacteria, randomly amplified polymorphic DNA (RAPD) fingerprinting of Salmonella typhimurium was carried out using random primers designated OPA-13 (5'-CAGCACCCAC-3'), OPB-10 (5'-CGTCTGGGAC-3'), OPB-18 (5'-CCACAGCAGT-3'), and OPJ-10 (5'-AAGCCCGAGG-3'), and its patterns compared with 6 representive intestinal, gram-negative bacterial strains, Vibrio parahaemolyticus, V. vulnificus, Enterobacter cloacae, Escherichia coli O157:H7, Pseudomonas aeruginosa, and Proteus sp., which are often found in foods. S. typhimurium had unique and distinct fingerprinting patterns. RAPD fingerprinting is thus concluded to be a rapid and sensitive method for the identification of S. typhimurium compared to conventional culturing procedures or immunoassays.

The present study was undertaken to evaluate the present status of intestinal parasitic infection in Seoul area, Korea. During the period from June 1985 to July 1986, a total of 5,251 stool samples were collected in Department of Clinical Pathology, Hanyang University Hospital and examined by formalin-ether sedimentation technique once for helminth ova and protozoan cysts. The results were summarized as follows: 1. The overall egg positive rate of intestinal helminthes was 2.53%; and 1.43% for Clonorchis sinensis, 0.7% for Trichuris trichiura, 0.13% for Metagonimus yokogawai, 0.06% for hookworm, and 0.02% for Ascaris lumbricoides, Diphyllobothrium latum and Hymenolepis nana, respectively. 2. The overall cyst positive rate of intestinal protozoa was 1.07%. Cyst positive rate was 0.06% for Entamoeba histolytica and 0.13% for Giardia lamblia, respectively. 3. Higher prevalence of intestinal parasitic infection was observed in male and in $21{\sim}50$ year-old groups. 4. The highest prevalence of Clonorchis sinensis infection was observed in 40th age group (3.4%), and male (2.3%) was more infected than female (0.7%) in general.
