Abstract:
AIM: To study testicular pathological change and its pathogenesis. METHODS:Testicular structure of alloxan induced diabetic rats was observed under light microscopy (LM)and transmission electron microscopy(TEM). Activity of superoxide dismutase(SOD),glutathione peroxidase(GSH-PX),nitric oxide synthase(NOS)and content of malondialdehyde (MDA),nitric oxide(NO) were detected biochemically in testicular homogenate. RESULTS: It is manifestated as atrophy of seminiferous tubule and germinal arrest under LM and expansion of mitochondria and smooth endoplasmic reticulum, cytoplasmic inclusion of sertoli cell under TEM.Activity of SOD, GSH-PX decreased while activity of NOS, content of MDA, NO increased in diabetic rats compared with control one. CONCLUSION: Disturbance of spermatogenesis and damage of sertoli cell are the main morphological change of diabetic testis, lipid peroxidation and NO may be involved in it.
