bcl-2 and c-myc protein expression were studied in 44 epidermal (8 seborrheic keratoses, 21 squamous cell carcinomas, and 15 basal cell carcinomas), and 26 melanocytic tumors(8 nevi, and malignant melanomas) by immunohistochemistry using the specific anti-bcl-2 and anti-c-myc monoclonal antibodies. 14 out of 15 basal cell carcinomas(BCC) (93.3%) showed expression of bcl-2 protein, 12 of which (85.7%) showed coexpression of c-myc protein. In the melanocytic tumors, 7 out of 8 nevi showed bcl-2 expression (87.5%). Five of these 7 cases (62.5%) also showed c-myc protein expression. Eight of 18 malignant melanomas(MM) (44.4%) showed expression of bcl-2 protein and 7 of these 8 cases (38.9%) also showed c-myc protein expression. All seborrheic keratoses and squamous cell carcinoma(SCC) were negative for bcl-2 proteins. 12 of 15 SCCs(80%) were positive for c-myc protein. In conclusion, bcl-2 and c-myc proteins were coexpressed in BCCs, nevi, and MMs. Coexpression of bcl-2 and c-myc proteins in these tumors was statistically significant(p<0.01), while no considerable differences of bcl-2 and c-myc expression were found between nevi and MMs. These results suggests that bcl-2 may cooperate with c-myc to promote tumorigenesis of BCCs, nevi, and MMs(p<0.01).

Gastric glomus tumor is an uncommon benign, submucosal neoplasm and does not require radical surgical procedure. Because there are no specific clinical or radiologic features associated with the glomus tumor, it can be recognized only by its histologic characteristics. We report a 30-year-old woman who had 10 years history of epigastric hunger pain. Radiologically, a gastric submucosal tumor was discovered, which was suggestive of leiomyoma. Gastric antrectomy was performed. The tumor cells showed immunohistochemical and ultrastructural evidence of smooth muscle differentiation.

We performed the intravitreal injection of air and pure perfluoropropane (C3F8) gas in the pigmented rabbits and observed the changes of gas levels by the ultrasonography. We also observed the changes of the intra-ocular gas levels by the ultrasonography and measured the intraocular pressures (lOPs) in 9 patients who had undergone vitrectomy and fluid-gas exchange with 20% sulfur hexafluoride (SF6) and 14% perfluoropropane (C3F8) gases. In the pigmented rabbits, the air was not expanded and completely absorbed within 2 days, and the C3F8 gas was expanded maximally at 3 to 7 days and completely absorbed after 3 weeks. Among nine human eyes treated with vitrectomy and fluid-gas exchange, the intraocular pressures were elevated above 25mmHg at 1 day after operation in 2 eyes, which were controlled with medical therapy. The lOPs were significantly correlated with the amount of the intraocular gases (r=0.3476, p<0.05). The assessment of intraocular gas level by ultrasonography seems to be easier and more objective method than others previously reported.

We also observed the changes of the intra-ocular gas levels by the ultrasonography and measured the intraocular pressures(IOPs) in 9 patients who had undergone vitrectomy and fluid-gas exchange with 20% sulfur hexafluoride(SF6) and 14% perfluoropropane(C3F8) gases.

Paederus dermatitis is a linear and self-healing blistering disease of the skin caused by contact with insects belonging to genus Paederus(Coieoptera : Staphylinidae). There have been only a few reports of paederus dermatitis in the southern part of Korea since 1968. We recently experienced a case of paederus dermatitis due to contact by P. fuscipes.

Sodium fusidate, obtained by fermentation of the fungus, Fusidium coccineum, has a steroid structure and shows a very high antitaphycoccal activity. The allergic potentirl of sodium fusidate is low and few cases of contact allergy to sodium fusidate have been reported. We present two cases of allergic contact dermatitis to Fucidin cintentione developed postoperative dressing of a skin biopsy and the other after laser treatment of a vascular nevi. The patch test results showed positive reaction to sodium fusidate in both cases.

p27kip1 is a cyclin-dependent kinase inhibitor that regulates progression from G1 into S phase. Aberrations in cell cycle control are often observed in tumors d might even be necessary in tumor development. Recent reports showed that low 7kip1 expression is associated with poor prognosis in several tumors and ukemia. To investigate the expression of p27kip1 in malignant lymphomas and ucidate the role of p27kip1 as a possible prognostic indicator, the authors rformed an immunohistochemical staining of p27kip1 correlated with Ki-67 belling index and clinical parameters. p27kip1 expression was reduced variably most malignant lymphomas and inversely correlated with Ki-67 labelling index +AD0-0.0151). Regarding chemotherapeutic response, p271kip1 expression in the mplete remission group showed statistically significant difference in pression compared to the progressive disease group (p+AD0-0.0021). There were gnificant differences in survival between cases with low and high p27kip1 pression (p+AD0-0.0071). In a multivariate Cox analysis, p27kip1 expression was dependent prognostic factors as well as other known prognostic factors cluding age, grade, stage and chemotherapeutic response. In conclusion, the udy suggests that reduced expression of p27kip1 protein may play a role in the thogenesis and biologically aggressive behavior of malignant lymphomas.
