Neonatal intestinal perforation is mainly caused by necrotizing enterocolitis, intestinal atresia, meconium ileus or unknown etiology. Occasionally, Hirschsprung's disease presents with neonatal intestinal perforation, of which, it is known that total colonic aganglionosis is common. Therefore, Hirschsprung's disease should be considered as a cause of neonatal intestinal perforation. The authors have experienced 3 cases of neonatal Hirschsprung's disease associated with colonic perforations. Cecal perforations were noted in 2 cases with aganglionosis from descending colon and sigmoid perforation in a case with aganglionosis in rectum. These cases will be discussed with literature review.

Chromophobe renal cell carcinoma (RCC) is an uncommon subtype of RCC having a better prognosis than clear cell RCC. Although there are several reports of seeding metastasis of RCC after biopsy, seeding metastasis of chromophobe RCC after surgical resection has seldom been reported. Here, we describe a case of multiple seeding metastases in the abdomen and pelvis 78 months after robot-assisted laparoscopic partial nephrectomy, without prior history of biopsy for chromophobe RCC in the right kidney. As magnetic resonance imaging (MRI) of the pelvic mass showed a similar appearance to the primary renal mass and displayed separate margins with the rectum and prostate gland, we were able to make a diagnosis before pathologic confirmation.

This study was conducted to establish a colostomy technique using cannulation in white Leghorn male chicks. A everted rectum method was used for colostomy from 3 to 20 months old roosters. After 2 or 3 days of operation, blood clots were taken off. At this time, a cannula was also inserted into artificisal annus to keep it open. The cannula was regularly exchanged at every 7 to 10 days. Polyethylene bag and plastic beaker were used for feces and urine collection, respect-ively. The present paper describes the methods of operation, cannulation after colostomy recturn and post-operation management. This method has succeeded in colostomising chickens that survive as long as their normal counterparts.

A clinical analysis was performed on 11 cases of metastatic lung cancer experienced at Department of Thoracic and Cardiovascular Surgery, Seoul National University Hospital during the 15 year period from 1970 to 1984. Of the 1lpatients of metastatic lung cancer, 4 patients were male and 7 patients were female and the age ranged from 27 years to 60 years old with the average of 38.8 years old. The sites of primary tumor were uterus and ovary in 5 patients, breast in 2, sarcoma in 2, rectum in 1 and testis in l.\ulcorner Tumor free intervals in each patients were as followed; unrecognition of primary site in 2 patients, simultaneous discovery of primary tumor and metastasis in 3, 14 months in 1, 4 years in 4 and 5 years in Twelve thoracotomies were performed in 11 patients and performed procedures were as followed; pneumonectomy in 1 patient, lobectomy in 7, wedge resection in 2, decortication and wedge resection in 1 and biopsy only in 1. Of the 11 patients, 4 patients died within one year after operation, 2 patients died within 2 years and 2 patients are alive over 5 years after operations. Other 3 patients are alive 2 months, 4 months and 9 months after operation at present.

Objectives : To evaluate the anti-tumor and synergic effect of Bojungikkeehapdaechilki-tang (BJDC) with doxorubicin. Methods : The inhibitory concentration (IC), $IC_{50}{\;}and{\;}IC_{90}$ of single use of doxorubicin and BIDC with their concomitant treatment against Colon-26 (murine rectum carcinoma) cell line were observed using MTT (microculture tetrazolium test) assay. In addition, their anti-tumor effects were also observed in xenograft nude mice models against Colon-26 cell line. Results : BJDC had only minimal direct anti-tumor effect against Colon-26 cell line but it reduced general depressed signs induced by implantation of the tumor cell lines and increased the total WBC and lymphocyte numbers. Conclusions : It is considered or expected that BJDC extract is reducing the critical toxicity of doxorubicin and has favorable synergic anti-tumor effect when administered conconitently with doxorubicin.

A 5-month old female Alaskan Malamute was referred to Veterinary Teaching Hospital, College of Veterinary Medicine, Kyungpook National University because of accidental ingestion of a box of staples. Clinical signs included anorexia, hematemesis, panting and depression. An aggregation of staples of 5 cm in diameter in the stomach, 4 pieces of staple in the small intestine and approximately 20 pieces in the rectum were identified in radiographic examination. A mass of staples in the stomach was removed surgically and some staples in the intestine passed without impediment through the gastrointestinal tract.

Eight species of bithyniids, Bithynia leachi, B. tentaculata, B. siamensis, B. misella, B. kiusiuensis, B. striatula, Bithynia sp. from Nepal and Gabbia australis were collected from 1957 to 1988. The samples were relaxed with pentobarbital and fixed with 70% ethyl alcohol. There was no significant difference in internal structure of soft body, except the male reproductive system. The alimentary canal of the bithyniids consisted of mouth, buccal mass, esophagus, stomach, intestine, rectum and anus. The heart consisted of an auricle and a ventricle, located at left side of the stomach in the visceral hump. The ctenidium comprised 40-70 subtriangular lamellae. Eight ganglia were located around upper esophagus. The female reproductive system comprised ovary, oviduct, spermaaheca, and albumin gland. The male reproductive system was composed of testis, seminal vesicle, prostate gland, vas deferens, penial duct, and penis in order. Male was distinguished externally from the female by a bifid penis.

Seven fractions were separated by silica gel chromatography from the diethyl ether souble portion of the methanolic extract of the cultured hoelen(Poria cocos Wolf). Three fractions were separated from the Fr.II and Fr.IV by rechromatography, respectively. The most active fraction, Fr.II 3 and Fr.IV 3, were separated to 2 and 4 fractions by preparative HPLC. On the result of antimicrobial test, triterpenoids fractions showed weaker effect than benzoic acid but Fr.II 3 1, Fr.II 3 2 had an excellent antimi crobial activity. Triterpenoids fraction of hoelen(Poria cocos Wolf) showed a high inhibition activity on the growth of lung cancer, ovary cancer, skin cancer, central nerve cancer and rectum cancer cell, especially the activity of Fr.II 3 1 and Fr.II 3 2 was the highest.

Colonoscopy is an important medical procedure for the diagnosis of various diseases like cancers in the colon and rectum. But it requires a lot of time for a doctor to acquire dexterous skills necessary to perform successful colonoscopy. Moreover, to many patients, conventional colonoscopy simply takes too long time. Therefore, some studies on the development of autonomous and more convenient colonoscope are carried out. In this Paper, we Propose a functional colonoscope robot system that has a locomotive function with a hollow body, a steering system, and other basic functions of typical conventional colonoscope systems. The concept and each component of the functional colonoscope system are described in this paper. In order to evaluate the functional performance of the colonoscope robot, we carried out in -vitro and in-vivo tests.

Diffuse cavernous hemangioma of the rectosigmoid is a rare lesion usually presented in children and young adult, often with life threatening hemorrhage. The clinical diagnosis is difficult and often delayed because of lack of awareness of the clinical features. We report a case of diffuse cavernous hemangioma of the rectosigmoid in a 12 year old boy who had undergone suture ligation under the impression of hemorrhoid at his age 3. Sphincter saving coloanal pull through procedure were applied as the surgical treatment. Sclerotherapy was needed with recurrent rectal bleeding 6 months after the pull through operation. The patient is well at 12 months follow-up.
