Methods: The experiment was conducted on Wistar breed rats. Propyphenazone was administered, in Tween 80 solution, using the stomach tube on days 8 to 14 of pregnancy at doses of 2.1 (PO), 21.0 (Pl), 210.0 mg/kg body weight (P2). Two control groups were done: T - receiving Tween 80, C — untreated control. The females were sacrificed on day 21 of gestation and the fetuses were delivered by cesarean section. The fetuses were sectioned in-situ and the fetal livers were taken for histological examination. The slides were examined using light microscopy after four stains: hematoxylin and eosin, silver Gomorii, van Giesson and histochemical by periodic acid-Schiff (paS).

Results: There were not internal and external macroscopic malformations. There were a adaptive changes and ecchymosis especially in group Pl. In the other groups, observation changes were not so often.

Conclusion: Those results suggest that propyphenazone may provide adaptive changes in fetal liver after short time application during pregnancy.
