In the study, we established the animal model of diabetic ED successfully. Modern medical methods such as routine lightscopy, pathology, transmission electroscopy, scanning electroscopy, fluorospectrophotometer and radio-immunity were employed. From the aspects of pathomorphism, cellular supermicrostucture and neurocrine, we observed the mixture's effect on status of the whole animal model and penial erection, the fast plasma glucose, protein non-enzyme gycosylation, nitric oxide synthase , testosterone. In contrast with control groups, the mixture could apparently slow down the corpus cavernosum penial, vascular, neural pathologic progression of the diabetic rats and had a better result than diabetic pill, invigorating yang and restoring normal capsule and amino guanidine.
