摘 要:目的:观察藜芦配伍人参对未成熟小鼠子宫系数、性激素水平、靶器官子宫和阴道的病理学变化的影响。方法:昆明种雌性小鼠120只,随机分为正常组、特异性雌激素受体拮抗剂ICI组(5 mg·kg-1)、藜芦组(0.045 g·kg-1)、人参低、中、高剂量组(12,18,24 g·kg-1)、ICI和人参低剂量混合组(混合低剂量组)、ICI和人参中剂量混合组(混合中剂量组)、ICI和人参高剂量混合组(混合高剂量组)、藜芦和人参低剂量配伍组(配伍低剂量组)、藜芦和人参中剂量配伍组(配伍中剂量组)、藜芦和人参高剂量配伍组(配伍高剂量组),每组10只,给药5 d后分别观察小鼠子宫系数,血清中雌二醇(E2),黄体生成素(LH),促卵泡生成素(FSH)的水平及子宫、阴道的病理学变化。结果:与正常组比较,人参各剂量组能使未成熟小鼠的子宫系数显著增加(P<0.05),E2含量明显升高(P<0.05,P<0.01),LH,FSH的水平显著降低(P<0.05,P<0.01),还能明显促进靶器官子宫、阴道的生长发育。配伍藜芦后,人参各剂量组的子宫系数明显降低(P<0.05,P<0.01),血清E2,LH和FSH水平明显升高(P<0.05,P<0.01),子宫和阴道的促生长发育作用减弱。结论:藜芦与特定剂量的人参配伍能够妨害人参的雌激素样作用。Objective : To investigate the estrogenic effect of the incompatibility of Veratrum nigrum and Panax gingseng on immature mouse. Method: One hundied and twenty female Kunming mice, were randomly divided into 12 groups: the normal group, estrogen receptor antagonist (ICI) group (5 mg·kg^-1), the V. nigrum (VT) group, (0. 045 g ·kg^-1), the low-, middle-and high-dose P. gingseng (GS) groups, (12, 18, 24 g·kg^-1 ) , ICI + low-dose GS group ( ICI 5 mg·kg^-1 + GS 12 g·kg^-1 ), ICI + middle-dose GS group ( ICI 5 mg ·kg^-1 + GS 18 g·kg^-1), ICI+high-doses GS group (ICI5 mg·kg^-1 +GS24 g·kg^-1), VT +low-dose GS group (VT 0. 045 g ·kg^-1+ GS 12 g·kg^-1) , VT + middle-dose GS group (VT 0. 045 g ·kg^-1 + GS 18 g ·kg^-1) , VT + high- dose GS group ( VT O. 045 g·kg^-1 + GS 24 g·kg^-1 ). The uterus index, estradiol ( E2 ) , luteinizing hormone (LH), follicle stimulating hormone (FSH), and the difference between uterine and vaginal histopathology were observed after 5 days. Result: Compared to the normal group, the uterus index increased (P 〈 0. 05) , E2 increased (P〈0.05, P 〈0.01), levels of LH and FSH decreased (P 〈0.05) in all doses of GS groups. Meanwhile, the growth and development of the uterus and vagina were promoted. While GS used with VT, uterus index decreased (P 〈0.05, P 〈0.01 ) , levels of Ez notably decreased (P 〈0.05, P 〈0.01 ) , levels of LH and FSH increased (P 〈 0.05, P 〈 0. 01 ) , and the degree of uterus and vagina atrophy was increased. Conclusion : VT could impair the estrogenic effect of GS in a certain dosage.
