PURPOSE: Growth hormone(GH) receptors have been detected in Sertoli cells and clinical observations suggested the involvement of GH action(either indirectly via IGF-I or directly) on testicular function. This study is aimed at assessing the effect of GH on cell death during Sertoli cell culture. METHODS: Sertoli cells(TM4, mouse, male, ATCC, USA) were cultured by using DMEM(Dulbecco' Modified Eagle' Medium, Biowhitteker, USA) and Fetal Bovine Serum(10%, GIBCO BRL, USA) with or without human recombinant growth hormone(Eutropin, LGCI, Korea) of different concentrations(10, 50, 100, 500 microgram/mL of media), in 34degress C, 5% CO2 incubator. After cultivation during 5 days, Sertoli cells were examined under light microscope(x400). RESULTS: Number of survival Sertoli cell was remarkably increased in the GH treated(50 microgram/mL in media) group(62.6+/-12.4) compare to control(22.4+/-4.8)(P<0.05). Degree of survival Sertoli cell was increased proportionaly until 50 microgram/mL in concentration of GH in media, but decreased in higher than it. CONCLUSION: GH has the protective effect on death of Sertoli cell and it depends on GH concentration.

BACKGROUND: Using c-fos expression one of the immediate early gene, as a marker of altered neuronal response, we investigated the effect of superior cervical ganglion block (SCGB) exhibiting the same effect of SGB of human on the activity of several brain regions which are considered as located on autonomic neural pathway and neuroendocrine axis in rat. METHOD: The 48 Sprague-Dawley strain rats were divided into 4 groups, as saline/stress (control) group, SCGB/stress (tested) group, saline group, SCGB group. Superior cervical ganglion block was conducted in the SCGB/stress group and SCGB group while saline/stress and saline group were sham operated. After then restraint stress was imposed on the animals of SCGB/stress group and saline/stress group. And 2 hour after injection (saline, SCGB group) or restraint stress (saline/stress, SCGB/stress group), c-fos protein (Fos) was localized by immunocytochemistry. RESULTS: Much stronger Fos immunoreactivity was induced in the several brain region of control group rats compared to other three groups and the numbers of Fos positive cell count of tested group were significantly decreased in paraventricular hypothalamic nucleus (p<0.01), A5 (p<0.01), raphe pallidus (p<0.05), nucleus tractus solitaius (p<0.01) compared to control group. CONCLUSION: This study demonstrate that superior cervical ganglion block attenuates stress induced neuronal activities of paraventricular hypothalamic nucleus, A5, raphe pallidus, nucleus tractus solitarius.

The purpose of this study is to identify the effects of sexual rehabilitation education on the knowledge of sexual activities and satisfaction of sexual activities of spinal cord injury clients by the method of Nonequivalent control group pretest-posttest group. The study period was between Jan. 6th and Apr. 11th, 1999. The experimental group was 21 spinal cord injury clients from one general hospital, and the control group was 21 spinal cord injury clients from three University hospital. Sexual rehabilitation education was done with manuals and video-tapes. Education time was 90 minutes a week for 4 weeks. The study tool was 20 questionnaires about sexual knowledge, designed Song, Chung Sook(1990) and 10 questionnaires from Derogatis's Derogatis Sexual Function Inventory for satisfaction of sexual activities(1979) translated by Jang, Soon Boke(1989). Analysis of data was done by x2 -test, t-test, repeated measures ANOVA and simple main effect with SAS/PC. The results are as follows. The 1st. hypothesis, "The group educated about the sexual rehabilitation has more sexual activities knowledge than those of the uneducated group." is significant statistically(F=12.06, p=0.001). The 2nd. hypotheses, "The group educated about the sexual rehabilitation has more satisfaction of sexual activities than those of the uneducated group." is significant statistically(F=5.04, p=0.030). According to the results, sexual rehabilitation education helps spinal cord injury clients to gain knowledge of sexual activities and satisfaction of sexual activities.

Three-types of expandable metallic stents were constructed to evaluate the differences between the stents : one, formed in a cylindrical zigzag pattern with stainless steel wire (Gianturco stent), another, made by coating the Gianturco stent with silicone rubber(Silicone stent), the third, made by coating the Gianturco stent with 24 carat gold(God stent) for tissue acceptance. A total of 69 stents(each 23 stents of Glanturco, Silicone, and Gold stents) of 8-12 mm in diameter and 20 mm long were placed into normal abdominal aorta, inferior vena cava and iliac artery of nine adult dogs for 2 weeks to 11 months. It was more difficult to introcuce Silicone stent into an introducing sheath than Gianturco or Gold stent due to the thickness of silicone rubber, Four Gianturco stents and three Silicone stents showed migration but Gold stent did not. Luminal narrowing or occlusion was noted in 3 Silicone stents, in 2 Gianturco stents, and in 1 Gold stent. Neointimal proliferation over the stent wires was more rapid and even in God stent than Silicone or Gianturco stent. Although further study is needed, Gold stent seems to be better than Gianturco or Silicone stent as an endovascular graft material.

Histiocytomas have rarely been reported in the lungs. We report an unusual benign pulmonary histiocytoma in a 45-year-old man and discuss the differential diagnosis. Chest CT showed a well-defined solitary pulmonary nodule of approximately 3 cm in size in the posterobasal segment of the right lower lobe. Posterolateral thoracotomy and wedge resection was performed. Gross examination revealed a mass, measuring 2.2 x 2.1 cm that had a circumscribed margin within the lung parenchyma. Microscopically, the tumor was entirely composed of large polygonal to round cells with a few chronic inflammatory cells. These tumor cells contained abundant cytoplasm which was either granular, eosinophilic or foamy. Immunohistochemically, these cells were diffusely positive for CD68 and focally positive for 1-antitrypsin, but negative for cytokeratin, vimentin, and smooth muscle actin.
