        摘   要   目的:研究黄芪总皂苷对气虚模型大鼠的补气作用及可能机制,为阐明黄芪补气的药效物质基础提供参考。方法:将40
        只雄性Wistar大鼠按体质量随机分为正常组、模型组、阳性对照组[补中益气丸,4.5 g/(kg·d),以生药量计]和黄芪总皂苷高、低剂
        量组[252、28 g/(kg·d),以总皂苷量计],每组8只。除正常组外,其余各组大鼠均采用“饮食不节+疲劳”法复制气虚模型。于造模
        同时,各给药组大鼠灌胃相应药物,正常组和模型组大鼠灌胃等体积水,每天1次,连续给药21 d。末次给药后,观察大鼠的一般
        情况;检测大鼠的体质量、胸腺指数、脾指数;记录其负重力竭游泳时间;测定其脾T淋巴细胞亚群CD3、CD4,肝组织中三磷酸腺
        苷(ATP)、二磷酸腺苷(ADP),血清中白蛋白(ALB),全血中红细胞计数(RBC)、血红蛋白(HBG)以及血清中超氧化物歧化酶
        (SOD)、丙二醛(MDA)、乳酸、乳酸脱氢酶(LDH)、肌酸激酶(CK)、白细胞介素 2(IL-2)、IL-12、肿瘤坏死因子α(TNF-α)的水平。
        结果:与正常组比较,模型组大鼠体质量、胸腺指数、脾指数、负重力竭游泳时间以及脾 T 淋巴细胞亚群 CD3、ATP、ADP、ALB 和
        IL-12水平均显著降低或缩短(P<0.05或P<0.01),MDA、乳酸、CK和TNF-α水平均显著升高(P<0.05)。与模型组比较,黄芪总
        皂苷高剂量组大鼠的体质量、脾指数、负重力竭游泳时间以及T淋巴细胞亚群CD3、ATP、ADP、ALB、RBC水平均显著升高或延长
        (P<0.05),MDA、乳酸、CK、TNF-α水平显著降低(P<0.05或P<0.01);黄芪低剂量组大鼠的负重力竭游泳时间、ATP、ADP、IL-2
        水平均显著升高或延长(P<0.05或P<0.01),MDA、乳酸、CK、TNF-α水平均显著降低(P<0.05或P<0.01)。与阳性对照组比较,
        黄芪总皂苷高剂量组大鼠脾指数、脾 T 淋巴细胞亚群 CD3 水平、负重力竭游泳时间、ATP 水平显著升高或延长(P<0.05 或 P<
        0.01),黄芪总皂苷高、低剂量组大鼠MDA水平均显著降低(P<0.05或P<0.01)。结论:黄芪总皂苷可通过减少机体乳酸的积累,
        降低CK活性、体内脂质过氧化物水平以及调节免疫,从而起到补气、延缓疲劳发生、增强运动能力的作用。

        ABSTRACT     OBJECTIVE:To study “Qi-invigorating”effect and its possible mechanism of total saponins of Astragalus
        membranaceus on rats with Qi-deficiency,and to provide reference for elucidating the material basis of“Qi-invigorating”effect of
        A. membranaceus. METHODS:Forty male Wistar rats were randomly divided into normal group,model group,positive control
        group [Buzhong yiqi pills,4.5 g/(kg·d)],A. membranaceus total saponins high-dose and low-dose groups [252,28 g/(kg·d),by
        the amount of total saponins] according to body weight,with 8 rats in each group. Except for normal group,the model of
        Qi-deficiency was made in other groups by the method of“diet disorder+fatigue”. At the same time,administration groups were
        given relevant medicine intragastrically,and normal group and model group were given constant volume of water,once a day,for
        consecutive 21 days. After last administration,the general situation of rats was observed;the body weight,spleen index and
        thymus index of rats were detected;weight-bearing swimming time was recorded;the levels of spleen T lymphocyte subsets CD3
        and CD4,the levels of ATP and ADP in liver tissue,serum levels of ALB,RBC and HBG in blood as well as the serum levels of
        SOD,MDA,lactate,LDH,CK,IL-2,IL-12 and TNF-α were all detected. RESULTS:Compared with normal group,body
        weight,thymus index,spleen index,weight-bearing swimming time,the level of spleen T lymphocyte subsets CD3,ATP,ADP,
        ALB,IL-2 and IL-12 were decreased or shortened significantly in model group (P<0.05 or P<0.01). The levels of MDA,
                                                            lactate, CK and TNF-α were increased significantly (P<
