ABSTRACT
Sequence information from the ribosomal RNA molecule can be used as a molecular clock. Therefore, 16S rRNA sequences have become a widely used tool in bacterial systematics, bacterial typing and studies of the composition of micro-organisms in environmental samples. Consequently, the databases are continuously updated with new 16S rRNA sequence information from different species. This in turn facilitates the identification of new isolates, which is important for the diagnosis of various infectious diseases in research. To development differential identification technique in the Yersinia species, the 16S rDNA for total 17 serotypes of Y. pseudotuberculosis type strains and one of Y. enterocolitica wild strain were amplified by polymerase chain reaction and cloned into pGEM-T vector, partially sequenced and analyzed. The 16S rDNA nucleotide sequence homologies among Yersinia strains were ranged 100% to 93.6%. Phylogenetic tree generated from 16S rDNA sequencing data showed different phyletic line that could be readily separated from each serotypes and other enteric bacterium.

Ulcerative colitis is a diffuse inflammatory disease which is characterized by the vascular congestion and superficial ulcerations in the mucosal and the submucosal layers of the rectum and colon. Extraintestinal manifestations such as arthritis, skin lesion, hepatobiliary and ocular diseases occur in a large number of patients with ulcerative colitis, though gastrointestinal symptoms of mucous and bloody stool, diarrhea and abdominal pain are frequently presented. The association of ulcerative colitis and hepatobiliary disease has been frequently reported in the western countries since the first description by Thomas C.H. in 1874. Fatty degeneration, chronic active hepatitis, cirrhosis, primary sclerosing cholangitis and hepatobiliary carcinoma are included in this list of complications. In the case of hepatobiliary carcinoma, however, the histological diagnosis has almost invariably been cholangiocarcinoma. We report a case of clinical ulcerative colitis with coneurrent hepatocellular carcinoma confirmed by the histologic examination of biopsy specimen in a 49 year old man with the relevant literatures.

Lipomas are one of the most common benign nonepithelial tumors of the colon and which are often detected incidentally at radiologic investigation or on operation without specific symptoms, Most of them look like submucosal tumor with yellowish-white color, smooth surface and solitary lesion. Sometimes they produce symptoms with large size, bleeding, constipation, diarrhea, abdominal pain, indigestion, intestinal obstruction and intussusception. Diagnosis can be made by colonoscopy, abdominal CT, MRI, barium enema and histologic confirmation achieves by the endoscopic polypectomy. Endoscopic polypectomy or mucosectomy can make it easy to remove them, as therapeutic method. We report 2 cases of lipomas successfully removed by endoseopic polypectomy-the one with two lipomas each at right descending colon and ileocecal valve and the other with one lipoma at the ileocecal valve-with the relevant literatures.

Tracheoesophageal fistula is a rare disease of abnormal communication between esopha- gus and respiratory system. The common causes are the acquired origins in adult such as trauma, infection of the adjacent organs, malignant tumor, and foreign body. Among the traumatic origins, chemical drug, the procedure of the dilatation on the stenotic area, blunt trauma(fall, collisions), penetrating trauma(bullet, knife), and pressure injury are much more common than others. Recently, trauma and foreign body in the esophagus and bronchus are becoming the main cause of the tracheoesophageal fistula, however the frequency of the development of tracheoesophageal fistula caused by the infectious diseases is getting decreased. Fibrinogen-thrombin glue stimulates the healing process of the wound and the ulcer. We treated a 52-year-old male patient with nan-inalignant tracheoesophageal fistula, who had symtoms of pharyngolaryngeal and chest discomfort concomitant with a paroxysmal cough on swallowing food which were caused by fish bone. The diagnosis of tracheoesophageal fistula was made by the esophagogram, chest CT, and esop aecopy. By using the therapeutic endoscopy with an injection of the fibrinogen-glue, the tracheoesopeal fistula was obliterated completely with dramatic symptomatic improvement. Here we conqluded that this method would be the one of the best methods for the treatment of tracheoesophageal fistula.

Lymphangioma is a benign tumor of lymphatic origin. Lymphangioma can occur anywhere in the body and only rarely affects the intestinal tract. Most intestinal lymphangiomas are asymptomatic and detected incidentally at autopsy or surgery. Occasionally, they may be large enough to present as a mass to cause obstruction or intussusception. Recently, we examined a case of a 27-year-old woman who complained right upper quadrant abdominal pain, increased bowel sound and weight loss. By surgical resection after the double contrast barium enema and colonoscopy, we could confirm cystic lymphangioma of the transverse colon. So we report this case with brief review of relevant literature.

Mucosal bridge, endoscopically observed, is a cord-like mucosal connection across the lumen. The bridge is very elastic and stretches easily, unlike granulation tissue. Mucosal bridges of the esophagus have been occasionally described in various circumstances, particularly in congenital or acquired origin as the inflammatory diseases. The occurrence of mucosal bridges due to inflammatory process may arise anywhere from the esophagus to the colon. It has been more frequently reported in the colon than in the esophagus, stomach, and duodenum. We experienced four cases of esophageal mucosal bridges and three of them were accompanied by esophageal diverticulum. We report these cases with a review of relevant literatures.
