1、中藥佳蓉片與雌激素對生殖系統(tǒng)作用的異同 摘要:目的觀察復(fù)方中藥佳蓉片(JRP)與乙烯雌酚(DES)對生殖系統(tǒng)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)三個不同劑量、DES(0.17mgkg-1)和生理鹽水(Con-trol0.5mL)每日分別灌胃處理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,成年小鼠實驗中另設(shè)灌服生理鹽水的假去卵巢組(Sham)和去卵巢組(OVX),觀察對子宮

3、DES組(29.511.7,P<0.01)和Sham組(33.612.1P<0.01);(2)VKEC值OVX+JRP三個不同劑量組的VKEC值與OVX比較明顯增加(分別為7.12.5,11.03.5,9.45.4,vs1.80.8,P<0.05),但增加值顯著低于DES組(5.71.4,P<0.05);(3)血清E2值OVX+JRP組和OVX+DES組的血清E2水平與OVX組比較無差異.結(jié)論JRP對小鼠子宮、陰道有弱雌激素樣作用,但作用強度遠低于DES,這種作用可能不是通過提高
