A case of bilateral absence of vas deference with sterility is reported. By new 15O cases of congenital absence of the vas deference, rather a rare congenital anomaly, were reported.

Angiogenesis is essential for the growth of solid tumors. Microvessel counts, which represent a measure of tumor angiogenesis, have been correlated with the overall survival of patients with a variety of malignancies. However, the significance of angiogenesis in renal cell carcinoma remains controversial. To determine whether angiogenesis correlates with prognosis of patients with renal cell carcinoma, we counted the microvessels within the primary tumors and compared their numbers with patients' prognosis. Tumor specimens from 42 patients were investigated. Microvessels were stained with anti-CD34 and anti-factor VIII-related antigen monoclonal antibodies. Significant correlation between microvessel counts for two antibodies was observed (r=0.875, p<0.01), although microvessel counts for CD34 were approximately two times higher. Microvessel counts were higher in clear cell than in non-clear cell carcinoma (p<0.05). These results suggest that immunostaining with anti-CD34 antibody may provide a more sensitive and accurate measure of tumor angiogenesis. There was no correlation between microvessel counts and nuclear grade, or TNM stage. In univariate analyses, nuclear grade and TNM stage were significantly associated with patient survival (p<0.01). But further studies on tumor angiogenesis of renal cell carcinoma are needed before it can be adopted as a prognostic marker.

The prevalence of syphilis was sharply decreased throughout the world since the introduction of penicillin into the treatment of syphilis in 1943, however recent in formations seemed to be increased in incidence of syphilis since about 1960. In Korea, recent trends of syphilis can hardly be assesed because there are few reports of it. In order to know the current incidence of syphilis in Seoul we carried out S.T.S. in 1046 healthy young men living in Seoul. At that we classified the man as syphilitic who has positive serologic test on both VDRL and RPCF and has not recieved regular antisyplulitic treatment in the past. The result reveala that the incidence of syphilitic infection is 1.72%, which is slightiy decreased statistical figure than in 1960s. There are no much differences in incidence between each group of age or educational degree. Among the 653 unmarried men, 62.3% of them had experiences of sexual contact and their sex partners were business girls, students and prostitutes in order of frequency.
