To a better understanding for molecular mechanism of oncogenesis in hepatoma, primary hepatocellular carcinoma and hepatoma cell lines (Hep 3B, PLC/PRP/5, Hep G2) were subjected to detailed cytogenetic analysis with G-banding method after cell cultures. No cloned chromosomal abnormalities were found in the primary hepatoma (below 100%). On the other hand, all hepatoma cell lines were cloned, the specific chromosomal abnormalities in Hep 3B were del(1p21), del(6q14) and t(1 ; 11)(pll ; q13). Genes of AMY1A, CGA, SEA and HSTF1 were located on 1p21 and 6q14 respectively. SEA and HSTF1 were located on 11q13. Regions of chromosome abnormalities in PLC/PRF/5 were the same found in Hep 3B. Besides, del(1q32) and del(1p32) were also cloned. Gene of CR1 and MYCL1 were located on 1q32 and 1p32 respectively. The characteristic findings of chromosome abnormalities in Hep G2 were del(1p31) and del(1q22). And GST1 and DAF were located on these regions each other Del(6q11) and del(1p22) were also found in Hep G2. From the above results, it is presumed that HBV may integrate to AMY1A gene or near this gene and leads to loss of functions to this gene. And impaired regulation of CGA occurs in next step. SEA, HSTF1 and MYCL1 oncogenes may act as a progressing factor of tumourgenesis in HBsAg(+) hepatoma. Some factors like chemical agents may cause functional loss of GST1 and DAF at first and functional loss of cell regulation of CGA occurs in next step. SKI oncogene may promote the progression of carcinogenesis in this cell line. Whether any causative agents are involved in carcinogenesis of hepatoma, functional loss of CGA gene is the most important factor in tumour-genesis in hepatoma.

OBJECTIVE: The patients of endometriosis may complain of dysmenorrhea, pelvic pain, and dyspareunia, but may be asymptomatic. We studied on the correlation between the pain and the psychologic stress, Also, we studied on the correlation between serum CA-l25 levels and the psychologic stress. METHODS: The data was obtained from il7 endometriosis patients. Psychological stress was studied with STAI(Stait-Trait Anxiety Inventory) and BDI(Beck Depression Inventory). We compared the degree of anxiety and depression according to existence of pain and the duration of pain. Also we examed the scores of STAI and BDI according to the level of serum CA-125. RESULTS: The pain group had more depression and anxiety, in comparison to the pain-free group. And the depression and anxiety significantly increased in long-term pain group. There was no correlation between the level of serum CA-125 and the depression,or axiety. CONCLUSION: The pain of endometriosis may play a role of pychological stress to the patients, so it seems to increase depression and anxiety.

Gonadotropin releasing hormone (GnRH) is believed to be pivotal hormone in hypothalamo-pituitary gonadal axis and the hypothalamus is believed as the exclusive organ producing GnRH and pituitary is for GnRH re ceptor until recently. Some reported the exptra-hypothalamic GnRH or extra-pituitary GnRH receptors from decades ago. The aims of this study are to confirm the existence of the GnRH receptor in bladder epithelial cancer cell, HT-1197 and HT-1376, and evaluated the possible role of the GnRH on cell cycle. The GnRH and GnRH receptor were detected by immunohistochemical staining and the effect of GnRH on cell cycle change in both cell line were studied by fluorescence activated cell sorter (FACS). The control cells were cultured at media supplemented with normal serum, and experimental group were cultured at media supplemented with charcoal stripped serum (CSS) which excluding peptide hormones except exogenous GnRH with different concentration. The GnRHs and GnRH receptors were detected at both cell lines and the cell cycle analysis showed that there were little difference in proportion of cell cycle among examined 10,000 cells in both cell lines, neither control nor experimental groups. This study shows that the GnRHs and GnRH receptors exist in bladder cancer cells and GnRH did not influence on the cell cycle progression. With this study, we suppose that the bladder cancer cells produce the GnRH and GnRH receptors and the role of the GnRF produced from the bladder cancer cells might be the autocrine rather than endo-or paracrine factor.

The dysplastic nevus is a rare form of melanocytic nevus in Korean people. During the past 5 years the authors experienced 5 cases in the St. Mary's Hospital and Kang Nam St. Mary's Hospital. The criteria and the histologic findings of dysplastic nevi are debated in the western literature. Clinically, all cases were greater than 5 mm in size with ill defined irregular borders and irregularly distributed pigmentation. Histopathologically, all cases showed numerous discrete individual nests of melanocytes located in the dermoepidermal junction and the papillary dermis and were characterized by extension of dermoepidermal component of the nevus at the "shoulder" beyond the dermal component of the nevus. There was no cytologic atypia of nevus cells in all cases. Our cases lacked personal or family history of malignant melanoma. Therefore, we believe our cases are nonfamilial, sporadic and benign nevi with no prognostic significance. A brief review of the literature and a discussion on the term "dysplastic" and clinicopathologic correlation are made.
8.A Clinical Analysis for Surgical Treatment of Axillary Osmidrosis by Subcutaneous Tissue Remover and Carbon Dioxide(CO2) Laser.
Korean Journal of Dermatology 2002;40(12):1474-1480
BACKGROUND: Axillary osmidrosis is a distressing problem characterized by and unpleasant odor, profuse sweating, and occasionally staining of clothes that may handicap those affected socially, psychologically and in the work place. Various types of surgical procedures have been developed for the treatment of axillary osmidrosis. However, it is still not clear whether which type of surgery can provide the best long-term results. OBJECTIVE: We evaluated the long-term(more than 2 years) follow-up results of subcutaneous tissue remover and Carbon Dioxide(CO2) laser for surgical treatment(Kim's operative method) of axillary osmidrosis retrospectively. METHODS: The number of patients who had been surgically operated wase 132 and among them, 62 patients were interviewed by telephone. The degree of recurrence, scar, satisfaction, the causes of dissatisfaction, and recommendation were evaluated. RESULTS: Thirty-eight of the 62 patients(61.3%) had no recurrence. Twenty-one patients(33.9%) of the 62 patients had rarely scar. Forty-five patients(72.6%) had a feeling of satisfaction. CONCLUSION: This combined method has the advantages of a high success rate, low complication rate and less scarring for the treatment of axillary osmidrosis based on the long-term evaluation.

Total hip replacement arthroplasties(THRA) have been done in 19 patients(31 hips), who were diagnosed ad ankylosing spondylitis from January, 1984 till July, 1993 at Seoul National University Hospital. All patients were male; 12 patients were affected bilaterally. Modified New York criteria was used as diagnostic criteria. HLA B27 antigen was positive in 18 cases(95%). The thoracolumbar spine and sacroiliac joint were affected in all cases and cervical spine was affected in five patients, among them, fiberoptic laryngoscopic intubation was needed in four cases. The trastrochanteric approach was used in 19 cases, which have severe limitation of motion and deformity of the acetabulum. For the prevention of postoperative heterotopic ossification, low dose radiation therapies were done in 10 cases of the risk group. The average follow-up period was three year and eleven months(two year-seven year and 10 months). Harris hip score and radiographs were obtained at each follow-up. The mean preoperative Harris hip score was 50(19–90), and finally, the mean Harris hip score was 87(68–96). Loosening of endoprothesis was noted in 3 cases and heterotopic ossification in 5 hips. Ischial enthesopathy was observed in 13 cases. Among the hips which had heterotopic ossification, four were class Ι by Brooker's classification and only one was class Ⅲ. No nonunion was observed in the cases which had trochanteric osteotomy expect breakage of wire in 4 cases. In THRA of ankylosing spendylitis, we obtained good result clinically and radiologically. In severely affected cases, we had used transtrochanteric approach and obtained good result due to better operative field. The incidence of heterotopic ossification was not significant and the prophylactic low dose radiation therapy seems to be effective in risk group.
