海马补肾丸滋阴补肾作用研究

目的采用多种实验模型评价海马补肾丸滋阴补肾作用,为临床提供实验依据。方法采用im氢化可的松致小鼠肾阳虚模型,观察海马补肾丸抗阳虚作用;采用ig甲状腺素加利血平致小鼠肾阴虚模型,观察海马补肾丸抗阴虚作用;采用im氢化可的松致大鼠肾阳虚模型,观察海马补肾丸对勃起功能的影响;采用去势雄性大鼠模型及正常幼龄雄性大鼠连续ig给药,观察海马补肾丸雄性激素样作用。结果给药10d,海马补肾丸1.1、2.2g/kg明显增加肾阳虚小鼠的自主活动次数,延长低温游泳时间,增加胸腺、脾脏的脏器指数;明显减少肾阴虚小鼠跳台错误次数、延长错误潜伏期,明显提高小鼠痛阈,增加小鼠胸腺、脾脏的脏器指数。给药2周,海马补肾丸0.56、1.12 g/kg明显增加大鼠bR/rR值、海绵体内压,明显改善勃起功能;明显增加去势大鼠血清睾酮(T)水平及前列腺、包皮腺、提肛肌的脏器指数;明显增加正常幼龄大鼠T、促卵泡激素(FSH)水平及精液囊的脏器指数。结论海马补肾丸具有明显的滋阴补肾作用。

Effect of Haima Bushen Pills on nourishing yin and reinforcing kidney

Objective To evaluate the effect of Haima Bushen Pills (HBP) on nourishing yin and reinforcing kidney, and study the mechanism of the action with aim to provide the experimental evidence for the clinic. Methods Rats model with kidney-yang deficiency was induced by hydrocortisone through intramuscular injection to observe the anti kidney-yang deficiency effect of HBP. The effect of HBP against kidney-yin deficiency was observed using the kidney-yin deficiency model induced by oral administration of thyroxine and reserpine. The effect of HBP on erectile function was observed by intramuscular injection of hydrocortisone in rats. Castrated male rats and normal young male rats were administered orally to observe the androgenic effect of HBP. Results After 10 d of administration, HBP at dose of 1.1 g/kg and 2.2 g/kg significantly increased the number of autonomic activities of kidney-yang deficiency mice, extended the duration of low-temperature swimming, and increased the organ coefficients of thymus and spleen. It also significantly reduced the number of platform jumping errors and prolonged the incubation period of errors, significantly increased the pain threshold and increased the organ coefficients of thymus and spleen in mice with kidney-yin deficiency. After 2 weeks of administration, HBP at doses of 0.56 g/kg and 1.12 g/kg significantly increased the bR/rR ratio and intravitreal pressure in rats, significantly improved the erectile function, significantly increased the serum testosterone (T) concentration and the viscera coefficients of prostate, foreskin gland and levator ANI of castrated rats. The serum concentration of testosterone (T), follicle-stimulating hormone (FSH) and viscera index of seminal vesicle were significantly increased in normal young rats after administration of HBP. Conclusion HBP has obvious effect on nourishing yin and reinforcing kidney.
