Hyperglycemia is the populest mediator. The oxygen radicals＇ production or the peroxide production in the mitochondria is preceded as a possible mechanism. TGF-beta is characterized as the main protagonist. TGF-b is a molecular mediator with adherent and hypertrophic properties in diabetic nephropathy. 20 Balb/c male and female mice were used. They were separated in two age groups, one of 4 weeks old （childhood, n= 10） and one of 6 weeks old （puberty, n=10）. An immunochemical study for TGF-beta was undertaken. The basal petal of the external membrane of Bowmen is thickened. In significant percentage the basal membrane was thickened and the peduncles merge together. Mature sperm cells were not normal. The two age groups did not present significant differences in morphology of the exocrine pancreatic cells. The augmented levels of TGF-beta expression promote the increased proliferation of the pancreatic glandular cells, the derangement of differentiation and the apoptosis rhythm. The renal function is diminished sooner than the clinical manifestations. The testicles are less influenced concerning principally the spermiogenesis.展开更多
