[The characteristics of the embryotoxic action of kalipsol].

Abstract

The effect of calipsol on the course of pregnancy and the embryonal development in albino rats was studied. It was found that single injections of the drug in a dose of 200 mg/kg on the 7th or 8th day of pregnancy induced no disorders in the pregnancy course and the embryonal development. At the administration in a dose of 40.0 mg/kg on the 11th, 13th, 15th days of pregnancy calipsol was shown to exert a marked embryolethal action and at the administration on the 7th, 9th, 11th days of pregnancy in doses of 20 and 40 mg/kg increased the number of fetuses with hemorrhages into the internal organs.
