A modified biological method using chicken embryos for the assessment of toxicity of the drug Inosine pranobex (made by Ewopharm - group I or Polfa - group II) was developed. The drugs at a dose of 50 mg/kg of body weight were injected into the while of an egg of embryos at the 6th day of embryogenesis. No teratogenic effects were found. Both drugs showed significant differences in embryotoxicity compared with the control group in favour of the drug made by Ewopharm. The differences were associated with hatching indices (59.88% in group I and 37.9% in group II), the deviation of the hatching diagram towards its delay and the prolongation of hatching time from pipping the shell to the disengagement from it. It was found that the drug of higher toxicity caused a delay of the process of embryogenesis; oedema of livers and kidneys were noticed as well. In chicken of group II a significant increase of alkaline phosphatase in the blood was also observed.

New Zealand white rabbits were given cypermethrin by gastric intubation at the rate of 0, 300, 600 and 1000 mg per 1 kg on the 4th, 10th, 13th and 18th day of their pregnancies. The fetuses were aborted on day 28. AH 166 fetuses were examined for external, internal and skeletal malformations or variations. There was no evidence of teratogenic action of cypermethrin in the rabbits; however, embryotoxic effects were detected. The results may have some value for prenatal toxicology of other mammal species and humans poisoned by cypermethrin, and of some benefit for the ecotoxicology of hares in the area where this pesticide is applied as a plant protection agent.
