运用微循环研究技术和器官运动描记技术观察了中药促孕液及其组分药红花、淫羊藿和益母草对大鼠肠系膜微循环和家兔子宫运动的影响。结果表明，促孕液能使大鼠肠系膜微动脉、微静脉扩张，毛细血管网交点数增加，具有显著的改善微循环的作用，其中红花和益母草起主要作用；促孕液也能缓和地促进子宫运动，其中红花起主要作用。这两种作用是促孕液治疗母畜卵巢静止和持久黄体性不孕症的部分机理。

入到培养24h的鸡胚成纤维细胞（CEF）中，即先加中药后接种病毒、先接种病毒后加中药、病毒和中药混合感作后同时加入。于病毒接种后72h测定NDVⅠ系的半数组织培养感染剂量（TCID50）和NDV Ⅳ系的血凝效价，以评价3种中药成分对NDV 感染细胞的影响。结果表明，APS和EPS仅在先于病毒加入时对NDV 有抑制作用，而EF 无论以何种方式给药均呈抑制作用。提示它们有一定的抗病毒作用，且与其浓度有相关性。

以苯甲酸雌二醇为阳性对照，生理盐水为阴性对照，观察了中药促孕液对21日龄雌性小白鼠卵巢发育、对成年去卵巢小鼠子宫内膜和阴道上皮结构以及阴道上皮脱落细胞角化率的影响。结果表明，促孕液能显著促进幼鼠卵巢发育，使其提早出现性成熟后的形态学特征；也能促进去卵巢小鼠子宫内膜和阴道上皮增生、分泌，提高阴道上皮脱落细胞的角化率，但其作用强度明显弱于雌二醇，提示促孕液具有微弱的雌激素样作用。这种作用是促孕液治疗母畜卵巢静止和持久黄体性不孕症的机理之一。

In order to compare the adjuvant activity of compound Chinese herbal medicinal ingredients (cCHMIs) and filtrate best prescription anddose, two initial screened cCHMIs were prepared and mixed with Newcastle disease (ND) vaccine respectively at three doses to vaccinate17-day-old chickens, taking the non-adjuvant and oil adjuvant vaccines as controls. On day 7, 14, 21, 28, 35 and 42 after vaccination, thedynamic changes of peripheral lymphocyte proliferation and serum antibody titers in the chickens were determined by means of MTT methodand hemagglutination inhibition test. The results showed that two cCHMIs could promote peripheral lymphocyte proliferation and enhanceserum antibody titer, of which adjuvant activity was similar to and even stronger than oil adjuvant in promoting lymphocyte proliferation atsome time points, and there was a certain dose-effect relationship. The best adjuvant activity of cCHMIs 2 in promoting cellular immunityoccurred at middle dose, and cCHMIs 1 in enhancing humoral immunity, at high dose. Based on good synergistic effects of their components,two cCHMIs would be expected as new-type immunologic adjuvants to substitute for oil adjuvant.

用新城疫Ⅳ系疫苗免疫雏鸡，在免疫前、后分别注射高、低剂量的当归多糖、黄芪多糖、板蓝根多糖、淫羊藿多糖、蜂胶多糖、淫羊藿黄酮、蜂胶黄酮、黄芪皂甙和人参皂甙等9种中药成分，用β微量法监测血清中血凝抑制抗体效价的动态变化。结果表明，9种中药成分均能不同程度地提高抗体效价，且与给药时间、剂量和免疫接种次数有一定关系。
