黄芪三仙汤对去卵巢大鼠中枢神经的保护作用

目的观察补肾活血中药黄芪三仙汤对去卵巢雌性大鼠脑内免疫细胞超微结构的影响。方法将50只雌性大鼠随机分为5组,即假手术组、模型组、高剂量治疗组、低剂量治疗组、脑复康对照组。模型组、治疗组、对照组行大鼠背部切口切除双侧卵巢造模,假手术组切除同样大小的脂肪。治疗组用黄芪三仙汤灌胃。于治疗4周后观察海马区星状胶质细胞情况及白细胞介素6(IL-6)水平、血清雌二醇水平。结果去卵巢能引发中枢神经系统(CNS)海马区星状胶质细胞增生。黄芪三仙汤能使星状神经胶质细胞数目减少,提高血清中雌二醇水平,降低海马组织IL-6水平,作用呈量效关系。脑复康不能提高血清中雌二醇水平。结论黄芪三仙汤能抑制CNS海马区神经胶质细胞增生,抑制CNS海马区的炎症反应。黄芪三仙汤可能是通过提高雌二醇的水平发挥对中枢神经的保护作用。

Protective Effects of Huangqi Sanxian Decoction on Central Nervous System of Ovariectomized Rats

Objective To observe the effects of Huangqi Sanxian Decoction,an invigorating kidney and activating blood Chinese medicine,on ultramicrostructure of brain immunocyte of ovariectomized rats.Methods Fifty female rats were randomized into five groups:sham operated group,model group,high-dosage treatment group,low-dosage treatment group and Naofukang control group.The rats models in these groups were established by excising two ovary from dorsal incision,and the same size of fat was excised in the sham operated group.The treatment groups were administrated Huangqi Sanxian Decoction by gastric gavage,the period of treatment for 4 weeks.The status of hippocampal artrocytes,the level of interleukin-6 and serum estradiol were observed after treatment for 4 weeks.Results Ovariectomy can induce hyperplasia of hippocampal artrocytes in the central nervous system,while Huangqi Sanxian Decoction can reduce the artrocyte number,increase the estradiol level and decrease the interleukin-6 level in a dose-dependent manner.Naofukang control group showed no influence on estradiol level.Conclusion Huangqi Sanxian Decoction can inhibit the artrocyte hyperplasia and inflammatory responses in the hippocampas of central nervous system.It exerts protective effects by increasing the estradiol level probably.
