There is considerable experimental evidence to indicate that tumor growth is dependent on angiogenesis. However, we do not understand how the angiogenic activity is initiated by a given tumor. There is a clear distinction between a stage without neovascularization, which correlates with a paucity of metastases, and a stage in which increasing neovascularization correlates with a rising rate of metastasis. The authors therefore asked whether the extent of angiogenesis in human prostatic carcinoma is correlated with the tumor grades or some growth factors. To investigate how tumor angiogenesis correlates with tumor aggressiveness, the authors counted microvessels within the various grades of invasive prostatic carcinomas of 44 patients and the nodular hyperplasias of 10 patients. Highlighting of the vessels by immunohistochemical staining for factor VIII-related antigen and assessment of the tumor aggressiveness by the degree of expression of some growth factors(transforming growth factor-alpha, and beta, epidermal growth factor), tumor necrosis factor-alpha and tumor grading(Gleason's score) were done. As a result, both microvessel counts and the expression of growth factors and tumor necrosis factor correlated with tumor grades. In conclusion, the number of microvessels per 200 X fields in the areas of most intense neovascularization in a prostatic carcinoma may be a predictor of the patient's prognosis. Therefore, assessment of tumor angiogenesis may prove valuable in selecting patients with prostatic carcinoma, especially small needle biopsy, for aggressive therapy.

We studied 105 patients with trasmural myocardial infarction who were admitted to Soonchunhyang university hospital from 1984-1988, and evaluated the clinical and coronary angiographic findings accordin to the age. The following results were obtained: 1) Among 105 patients with myocardial infarction, the prevalent age were sixth and seventh decade(27.6%) and the ration of male to female was 2:1, But the raion of male to female was 5.3:1 under the 50 years of age. 2) In frequency of risk factor of coronarhy heart disease, cigarrette smoking was present in 66.7%, hypertensio in 44.8% and hypercholesterolemia in 28.6%. The mean number of risk factor was 1.3 under the 50 years of age and was 1.7 over the 50 years of age. 3) Anterior myocardial infarction was most common under 50 years of age whereas anterior and inferior myocardial infarction occur similarly over the 50 years of age. 4) By coronary angiography, one vessel disease of stenosis of left anterior descending coronary artery was common findings under 50 years of age, but multivessel disease was common findings over the 50 years of age.

PURPOSE: Lower caliceal stones treated with ESWL do fail to pass more frequently than middle or upper caliceal stones. We analyzed the results of ESWL of renal caliceal stones according to the location of calix. MATERIALS AND METHODS: We reviewed the stone-free rate in 119 caliceal stone patients treated with 3rd generation lithotriptor, EDAP LT-02 according to the caliceal location of the stone. Location of the stones were upper calix in 30, middle calix in 30, and lower calix in 59 patients. RESULTS: Stone-free rate was 90.0%(27/30 patients) in middle caliceal stones, 74.6%(44/59 patients) in lower caliceal stones, and 66.7%(20/30 patients) in upper caliceal stones. CONCLUSIONS: Stone-free rate of lower caliceal stones is higher than upper caliceal stones.
