OBJECTIVETo study the effects of super painkiller on the sexual function of male Wistar rats with diabetes.
METHODSThirty-two Wistar rats at 3-5 months of age were divided into two groups at random: 22 in the diabetes group, and 10 in the control group. After 72 hours, the former was further divided into 2 subgroups: non-treatment and super painkiller treatment. In 5 weeks, blood glucose was determined. After the apomorphines experiment, the rats were killed, blood taken from the vein, homogenate prepared from the isolated testis tissue and the level of NO and NOS in the serum and tissue homogenate surveyed, separately.
RESULTSCompared with the control group, serum NO and NOS of the diabetic rats dropped sharply. Compared with the non-treatment group, the serum NO and NOS of the super painkiller treatment group were very high and the difference was significant (P < 0.01). Apomorphine injection showed that the times of penis erection of the treated rats were more than those of the non-treatment group (P < 0.01) , but the difference was not significant compared with the control (P > 0.05).
CONCLUSIONSuper painkiller has sure effect of reducing blood glucose, with a certain curative value for sexual and reproductive malfunction of diabetic rats.

AIM: To study the mechanism of diabetic cardiomyopathy and abnormality of oxygen free radicals. METHODS: The contents of myocardial cytosolic cytochrome C, mitochondria cytochrome C, mitochondrial calcium, NO, MDA and the activity of SOD and NOS were determined in diabetic rats induced by STZ. The pathological changes were observed under transmission electron microscope. RESULTS: Compared to the normal and ganoderma group, the levels of mitochondrial NO, iNOS, MDA, calcium and plasma Cyt-C in rat myocardium were higher (P<0.05), while mitochondrial Cyt-C and SOD were lowered in model group (P<0.05). The bouncary indistinct, disorganization, a focal loss of muscular fibril, myocardium mitochondria swelling, pulmonary vascular endothelial cellular swelling and obstructed lumen of the capillary were also observed under transmission electronic microscope. CONCLUSION: The findings indicate that oxyradical and lipid peroxidation might be associated with the damage of myocardial mitochondria in NIDDM rats. Cyt-C and mitochondrial calcium is also involved in the process.
