PURPOSE: Malignant disease of the anus is rare. Abdominoperineal resection was formerly considered to be the treatment of choice. But, in recent, less ablative and more effective combined therapeutic modalities have been developed. METHODS: we analyzed 33 patients who were diagnosed and treated as anal cancers at the Department of Surgery, Gospel Hospital, Kosin Medical Collage, from July 1, 1988 to Nov. 30, 1997. RESULTS: The ratio of male to female was 1.4:1 and mean age was 56.7 years old. Twenty-two (84.8%) of these cancers were located in the anal canal and 5 (15.2%) in the anal margin. Three main histologic types of the anal cancers were identified: squamous cell carcinoma was the most common lesion, accounted for 17 cases (51.1%), adenocarcinoma accounted for 8 cases (24.2%), malignant melanoma accounted for 8 cases (24.2%). The overall 3-year survival rate and 5-year survival rate of anal cancer were 54.1%, 41.7%. Eleven patients with squamous cell carcinoma were treated curatively: 6 patients were treated with chemoradiotherapy, 3 patients with abdominoperineal resection, one patient with chemoradiotherapy and abdominoperineal resection, one patient with local excision. CONCLUSION: In survival rate, there were no significant differences between chemoradiotherapy group and surgical treatment group. In squamous cell carcinomas, chemoradiotherapy had anal sparing benefit without loss of survival. On univariate analysis, T, N, type of treatment, histologic type had no statistical significances on survival. On multivariate analysis, location of lesion and distant metastasis had statistical significances.

It is well established that mast cell proliferation and maturation are regulated by two principle cytokines, IL-3 and the c-kit ligand stem cell factor (SCF). Previous reports have demonstrated that bone marrow-derived IL-3-dependent mast cells exhibit the characteristic apoptosis on removal of IL-3. To know how the number of mast cells is controlled, we observed the effects of nitric oxide (NO) on the murine bone marrow-derived cultured mast cells (BMCMC). Apoptosis was measured by the analysis of flow cytometric data and electrophoretic evidence of DNA fragmentation. Our data showed that sodiurn nitroprusside (SNP)-a NO releasing substance- induced apoptosis in BMCMC. Cell cycle analysis showed that the number of the G,/G, and S phase decreased markedly, while the percentage of cell in G,/M phase was increased. Also, SNP alone induced cell death, whereas SNP in combination with SCF markedly decreased cell death of BMCMC. SNP-induced apoptosis was partially inhibited by the treatment of BMCMC with SCF. Our results suggest that NO might have sorne role in the regulation of the number of mast cells.

Multiple gastric caner, now considered to be a sort of multiple primary cancer by Moertel's classification, is a special type of cancer in which two or more tumor lesions arise independently from the stomach. Although its incidence is rare and it has never been reported in Korea yet, the report of multiple gastric cancer is increasing with lengthened life survival and improved diagnostic method. We recently experienced two cases of triple gastric cancer, the one in 53-years-old male who had well differentiated adenocarcinoma(EGC IIb+c) on antrum, poorly differentiated adenocarcinoma on cardia and moderately differentiated adenocarcinoma on mid-body, and the other in 65-years-old female who had two poorly differentiated adenocarcinoma on cardia and anterior wall of low body and moderately differentiated adenocarcinoma (EGCIIc) on posterior wall of low body. Triple gastric cancer is rare, so we reported 2 cases of triple gastric cancer.

BACKGROUND: Diverticulosis of the cecum and ascending colon is a rare disease in Western countries, it is more common in the Orient. Making the diagnosis preoperatively could be difficult, and the intraoperative assessment and decision of optimal treatments are difficult. METHODS: Therefore, we reviewed the patient's charts of diverticulosis of the cecum and ascending colon at our hospital from 1992 to 1997. RESULTS: During the past 5 years, a total of 53 cases of diverticulosis of the cecum and ascending colon had been treated at this hospital. Mean age was 41.8 years (range 20-70). The male to female ratio was 1.8 : 1. Frequent complaints were abdominal pain (46 cases, 86.8%), followed by diarrhea (5 cases, 9.3%), indigestion (4 cases, 7.5%), and bowel habits change (2 cases, 3.8%). Mean duration of illness was 3.5 days(range 24 hours~15 days). In non-surgical cases, diagnoses were established with barium enema, CT scan, or ultrasonography. The accuracy of these methods was 91%, 75%, and 25%. In surgical cases, the preoperative diagnoses were appendicitis(13 cases, 50.1%), diverticulitis (7 cases, 31.8%), and abscess (2 cases, 9.1%). Treatments of the cecum and ascending colon diverticulitis were conservative management (3 teases,58.5%) and surgical treatment (22 cases,41.5%). The operative procedures were right hemicolectomies (2 cases), ileocecal resections (2 cases), diverticulectomies (6 cases) and appendectomies only (11 cases). CONCLUSION: These results suggest that correct diagnosis of the diverticulitis of the cecum and ascending colon made before treatment is very important because correct assessment of diverticulitis intraoperatively is difacut. Liberal use of diagnostic modalities could facilitate to make correct diagnosis to set a proper plan for treatment.

Uterine didelphys is a congenital malformation characterized by the presence of two separated hemiuteri andhemivaginas, due to lack of midfusion of the Mullerian ducts. We report a case of UD-BHRA(uterine didelphys withblind hemivagina and ipsilateral renal agenesis), a rare type of uterine didelphys charaterized by symptomaticunilateral hematocolpos due to blind hemivagina after menarche and ipsilateral renal agenesis. The MRI findings in22-year-old woman with bilateral ovarian tumors demonstrated two separated uterine horns and cervical and vaginalcanals, with left hematocolpos and left renal agenesis.

OBJECTIVES: Copper and Zinc, the trace elements of a living body, take a part in immunologic mechanism and induce the pulmonary fibrosis which is the pathologic progress of pneumoconiosis. This study was performed to assist the identification of the pathologic process of pulmonary fibrosis in pneumoconiosis. METHODS: The subjects of this study was 200 diagnosed persons as pneumoconiosis, of whom 100 persons was the visitors in the outpatients departments of pneumoconiosis and 100 admissive pneumoconiosis patients. The serum copper and zinc are measured and com pared. RESULTS: The mean serum copper concentration of visitor group was significantly higher than that of control group, and that of stage V3 subgroup of visitor group was highest because of their advanced fibrosis. But, there was not the difference of serum copper concentration between patient and control group. We thought that the reason was poor nutritional and health status of the patient. The mean of serum zinc concentration of visitor and patient control was lower than that of control group. As the degree of pulmonary fibrosis was more severe from stage Vl, V2, V3 of visitor to stage Pl, P2, P3 of patient, the mean of serum zinc concentration was lower. The ratio of serum copper/zinc of visitor and patient was higher than that of control, and that of patient was higher than that of visitor. Those results showed that the ratio of serum copper/zinc ratio more greatly expressed the degree of progression of pneumoconiosis than only copper or zinc concentration by adjustment of nutritional and health status of the patient. CONCLUSIONS: As above study results, the degree of pulmonary fibrosis of pneumoconiosis could be estimated by means of serum copper/zinc ratio.

BACKGROUND AND OBJECTIVES: The purposes of this study was to investigate the characteristics of gentamicin-induced vestibulotoxicity of s otolith organs by assessing the results of earth vertical and the off-vertical axis rotation tests with a morphologic study. MATERIALS AND METHODS: Rabbits were grouped into two groups, ototoxic and ototoxic prevention group. Vestibulotoxicity was induced by injecting gentamicin (GM) into the peritoneum. Prevention of the vestibulotoxicity was studied by injecting NMDA receptor inhibitors (MK-801), iron chelating agents (deferoxamine) peritonially, and osmotic pumps filled with neurotrophic factors (GDNF, BDNF), respectively. The animal rotation system was designed to rotate the animal sinusoidally or in velocity step (constant velocity) rotation. Off-vertical rotation was applied to evaluate the otolithic function. Scanning electron microscopy were examined for the structural changes of the otolithic organs. RESULTS AND CONCLUSIONS: GM-induced vestibulotoxicity was confirmed by gain decreasing in the earth vertical SHA rotation test and bias decreasing in the off-vertical rotation test. However, changes in modulation was not definite. Bilateral prevention of GM-induced vestibulotoxicity was confirmed by systemic injection of deferoxamine and MK-801, and characteristics of unilateral prevention was confirmed by local application of the neurotrophic factors using osmotic pumps. In the SEM study, the GM-induced hair cell damages of the vestibule were identified, which was prevented by the preventive drugs. The reduction of bias value without change of modulation was comparable with the reduction of gain in the earth vertical axis rotation after GM-induced vestibulotoxicity.
