To study the probable negative influence of the complex remedy "Tireoton" on the reproductive function of the laboratory animals the following tests have been carried out, namely the probable occurrence of embryo-toxicity, teratogenicity, foetotoxicity and its influence on the postnatal development of the laboratory animals progeny. The experiments have been carried out of the white Wistar rats. It has been established that the "Tireoton" at the doses of 75 and 750 mg/kg has no embryotoxic, teratogenic and fetotoxical effect. The introduction of the "Tireoton" at the dose of 750 mg/kg since 6th to 19th day of pregnancy does not influence on the postnatal development of white rats progeny.

The experiments were carried out on white Wistar rats. The probable embryotoxic, teratogenic and fetotoxical influences of the plant remedy "Pancreophyt" at the doses of300 (1/10 DL50) and 600 mg/kg (1/5 DL50) were studied. The findings have shown that all indices of embryo lethality (the number of implantation sites, the number of alive fetus and the number of resorptions) in female white rats treated with the "Pancreophyt" do not differ significantly from the indices of the control group. The mass and craniocaudal dimensions of the fetus in the experimental group corresponded to the indices in the control group. In the second set of experiments the influence of the "Pancreophyt" (300 mg/kg) on the postnatal development of white rat offspring was studied. It was revealed that the death of infant rats was noted only on the 1st day of observation and was 4,7%; the liveweight gain and linear size of infant rats do not differ from the indices of those in the control group.
