Abstract
In Clauberg rabbits, the effects of the following plants on the progesteroneinduced endometrial carbonic anhydrase increase were studied: Radix Polygon multiflori, Cortex Acanthopanacis radicis, Herba Epimedii and Semen Cuscutae. All of the plants were administered orally as a water extract.
Progesterone manifested a typical increase in endometrial carbonic anhydrase. Radix Polygon multiflori and Cortex Acanthopanacis radicis administered simultaneously with progesterone suppressed the endometrial response, 0.01-0.1 g. of the former and 10-50 g. of the latter being effective for the inhibition of the effect of 2.0 mg. of progesterone. Herba Epimedii and Semen Cuscvtae did not interfere with the progestational effect of progesterone.
