Abstract

The pregnancy period is characterized by the critical time of the pregnant mother's exposure to external impacts, which are most severe during the so-called embryonic period. The study aimed toward study the effects of warfarin in the developing rat fetus. Three-month adult virgin female Wistar albino rats (Rattus norvegicus) were used. They are Left to adapt for one week and then isolated with males by two females with one male for mating determined the zero-gestation day. Pregnant females were arbitrarily divided into three equals with eight rats for each. The first group is control kept without any treatment The second and third groups take 0.1 or 0.05 mg/kg B.t of warfarin respectively, daily from (zero - 15th) day of gestation. The Collection of the blood samples from heart of pregnant rats for biochemical study via using Kit of ELISA technique to estimation the concentration of Osteocalcin and matrix Gla protein. The pregnant animals were sacrificed at (16th) day of gestation The fetuses’ specimens were collected for histological processing. Major anomalies were observed on incomplete ossification of the hind leg and wavy ribs by using double stained Alizarine red and Alcian blue. The histological examination of the vertebral column in the group of treated fetuses reveals degeneration at the vertebrae, damage to the intervertebral tissue, hemorrhage and necrosis. They are a significant decrease in the Matrix Gla protein and Osteocalcin in serum of pregnant rats.
