Adult Wilms' tumor, unlike that of childhood, is a rare disease. Microscopically, the tumor is fundamentally characterized by triplastic embryonal renal tumor composed of variable amounts of metanephric blastema and its epithelial and stromal derivatives but rarely a small group of tumors composed virtually entirely of differentiated epithelial derivatives, the abundance of tubular structures. These monomorphous epithelial type of Wilms' tumor tended to have an early onset and benign course. Grossly, classic Wilms' tumor is a solid tumor, but very rarely shows cystic change and may lead to misinterpretation as a polycystic kidney or multicystic nephroma. Here, we reports a case of primary renal tumor, grossly very similar to a multicystic kidney but histologically represent a tubular monomorphous epithelial variant of Wilms' tumor occured in 63 year old male adult.

Additional two cases of Klinefelter's syndrome with a literatural review was presented Two cases were revealed characteristics of Klinefelter's syndrome such as small testes, hyalinization of seminiferous tubules, azoospermia, increased FSH, normal 17-ketogteroid and positive sex chromatin. One case was associated with left inguinal crytorchidism.

To elucidate the effect of copper on the 3'-methyl-4-dimethylaminoazobenzene(3'-MeDAB) induced hepatic carcinogenesis, Sprague-Dawley rats were divided into 4 groups according to 3'-MeDAB and copper administration: I. noraml control, II. copper only, III. 3'-MeDAB only, IV. 3'-MeDAB plus copper. The animals of groups III and IV were fed experimental diet containing 0.06% 3'-MeDAB. Copper was administrated intraperitoneally in a dose of 0.5 mg, twice a weak. Animals were sacrificed at different intervals. Liver weight, hepatic copper content and gross and microscopical changes of the liver were examined and the cell kinetics of various lesions in the hepatic carcinogenesis was studied by applying the immunohistochemical method for bromodeoxyuridine(BrdU). The hepatic copper content was significantly increased in animals given copper but returned to the normal value after cessation of adminstration. 3'-MeDAB administration caused oval cell proliferation and produced hyperplastic nodules, cholangiofibrosis and carcinoma of the liver. Simultaneous administration of copper did not alter the incidence of 3'-MeDAB induced lesions, except for carcinoma. The liver weight and the size of hepatic nodules and masses were smaller in group IV than in group III. The liver weight as well as the nodularity and the mass formation continued to increase affect cessation of 3'-MeDAB administration. Copper did not affect the BrdU labelling indices of the hepatic lesions induced by 3'-MeDAB. The oval cell proliferation and the BrdU labelling indices of the oval cell and the hyperplastic nodule were decreased, but the incidence of cholangiofibrosis and its BrdU labelling index were still elevated after cessation of 3'MeDAB administration. These findings indicate that copper could delay the developement of 3'-MeDAB induced hepatic lesions, but not suppress, since copper does not stay long enough to accumulate in the rat liver, and that copper could not affect the proliferation of 3'-MeDAB induced hepatic lesions once developed.

OBJECTIVES: This study is aimed to quantify the complex dynamics of beat-to-beat fetal heart rate(FHR) fluctuations by using approximate entropy(ApEn) which is a recently developed mathematical formula quantifying regularity and also to determine the differences between normal fetuses and growth retarded fetuses. BACKGROUND: Recently, some measures of heart rate variability and nonlinear "complexity" of heart rate dynamics have been used as indicators fetal well-being. Approximate entropy is a new mathematical approach and formula to quantify regularity in data. It has been shown to provide new information in fetal heart rate analysis. Because growth retarded fetus accounts for a significant increase in perinatal morbidity and mortality, than normal fetus, we postulated that there existed important differences between normal fetuses and growth retarded fetuses. METHODS: We analyzed FHR tracings for 40 minutes, and approximately 5,000 points in normal fetuses(n=315) and growth retarded fetuses(n=76). The overall "complexity" of each FHR time series was quantified by its approximate entropy, measure of regularity derived from nonlinear dynamics, "chaos theory". RESULTS: Mean baseline FHR increased in growth retarded fetuses than normal fetuses. And the FHR ApEn significantly decreased in growth retarded fetuses(ApEn=0.623) compared to that of the normal fetuses(ApEn=0.868) throughout all gestational ages(p < 0.001). CONCLUSIONS: The ApEn of FHR decreased in growth retarded fetuses throughout all gestational ages. These findings indicated that decreased ApEn values of FHR are associated with sickness and the greater perinatal morbidity risks. Therefore ApEn quantifies subtle changes in FHR regularity and promises for new information in FHR analysis.
