By : Margit Semmler1, Abdel-Baset M. Aref2 Abstract The present study aims to evaluate the possible preventive effect of melatonin against dimethyl-benz(a)anthracene (DMBA) induced cell proliferation and DNA synthesis in epithelial cells of cortical and medullary renal tubules in mice applying the method of quantitative autoradiography. Exposure to a single injection of DMBA (10mg/ 100g […]

By : T. El-Sayed Ali1*#, S. H. Abdel-Aziz1, Abstract This work analyses the spermatogenesis in the males of Scarus ferrugineus from histological and ultrastructural points of view. This study was carried out during the period of formation of spermatozoa thus being able to determine the pattern of spermiogenesis which is important for phylogenetic analysis. Histological […]
