镇痛灵对雄性1型糖尿病大鼠性功能的影响

目的 :本实验以成年雄性大鼠为研究对象 ,观察和探讨中药镇痛灵对糖尿病大鼠性功能的影响。　方法 :3～ 5月龄雄性Wistar大鼠 32只 ,随机分为糖尿病组 2 2只 ,正常对照组 10只。 72h后 ,将造模成功的糖尿病大鼠随机分为 2组 :未治疗组 ;镇痛灵治疗组。第 5周测血糖 ,阿朴吗啡勃起实验后 ,乙醚麻醉下断头取血 ,分离血清 ,取一侧睾丸组织制成匀浆液 ,测定血清及组织匀浆中NO及NOS水平。　结果 :糖尿病大鼠与正常对照组比较 ,血清NO、NOS明显降低 ,差异有高度显著性 (P <0 .0 0 1) ;镇痛灵治疗组血清NO、NOS值与未治疗组比较明显升高 ,差异有显著性 (P <0 .0 1) ;阿朴吗啡勃起实验证实 ,镇痛灵治疗组大鼠阴茎勃起次数明显多于未治疗组 ,差异有显著性(P <0 .0 1) ,而与正常对照组比较 ,差异无显著性 (P >0 .0 5 )。　结论 :复方中药合剂镇痛灵有降血糖作用 ,对糖尿病并发的性功能障碍有一定治疗作用。

Study of the Effect of Super Painkiller on the Sexual Function of Male Rats with Type 1 Diabetes

OBJECTIVE: To study the effects of super painkiller on the sexual function of male Wistar rats with diabetes. METHODS: Thirty-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. RESULTS: Compared 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). CONCLUSION: Super painkiller has sure effect of reducing blood glucose, with a certain curative value for sexual and reproductive malfunction of diabetic rats.
