Methods: Separate and abstract the effective components of Huangqi (Omni-Saponin、total-flavone) and Danshen (Danshen-ketone、 Danshen-Quinone). Applying L-Arginine methyl ester to pregnant rats by I. P to make Nitrogen Oxide Synthesis blocking models (uterus-placenta-fetus lacking blood and oxygen model or pregnant hypertension syndrome model). On day 12, 18 of pregnancy paunched the rats and took out the fetus and placenta/uterus. Measured the basal BP during pregnant period and BP、protein、basal activity each day. Observed placenta/deciduas ultramicroscopic structure by electron microscope and took count of languishment cells. Measured the expressive intensity of bcl-2、Bax of placental nutrient cells by SABC method.
