1、中药佳蓉片与雌激素对生殖系统作用的异同 摘要:目的观察复方中药佳蓉片(JRP)与乙烯雌酚(DES)对生殖系统的不同作用.方法用JRP低(JRP-L,6gkg-1)、JRP中(JRP-M,12gkg-1)、JRP高(JRP-H,24gkg-1)三个不同剂量、DES(0.17mgkg-1)和生理盐水(Con-trol0.5mL)每日分别灌胃处理70只未成年(17d)昆明小鼠3d和50只去卵巢成年(60d)昆明小鼠28d,成年小鼠实验中另设灌服生理盐水的假去卵巢组(Sham)和去卵巢组(OVX),观察对子宫
2、质量/体质量百分比(PUM)、阴道上皮细胞角化百分比(VKEC)、血清17β雌二素(E2)水平的变化.结果(1)PUM值JRP不同剂量处理未成年小鼠3d后,JRP-M组的PUM值高于Control组(12.52.3,vs8.21.4,P<0.01),但明显低于DES组(37.03.8,P<0.01).JRP处理成年去卵巢小鼠28d后,OVX+JRP三个组的PUM值显著高于OVX组(分别为10.91.9,11.33.3,14.67.8,vs8.41.4,P<0.05),但明显低于OVX+
3、DES组(29.511.7,P<0.01)和Sham组(33.612.1P<0.01);(2)VKEC值OVX+JRP三个不同剂量组的VKEC值与OVX比较明显增加(分别为7.12.5,11.03.5,9.45.4,vs1.80.8,P<0.05),但增加值显著低于DES组(5.71.4,P<0.05);(3)血清E2值OVX+JRP组和OVX+DES组的血清E2水平与OVX组比较无差异.结论JRP对小鼠子宫、阴道有弱雌激素样作用,但作用强度远低于DES,这种作用可能不是通过提高
