Abstract:
The embryotoxicity and teratogenicity of alpha-asarone were investigated in mice. The drug was dissolved in corn oil, and administered daily, by gavage, on days 6 to 15 of gestation, at 0 (controls), 5, 15, 30 and 60 mg/kg. Fetuses were removed on day 18 by caesarean section and examined using routine teratological methods. A significant maternal toxicity was observed in dams given 60 mg/kg, as indicated by a reduced weight gain. An embryolethality was observed in 15, 30 and 60 mg/kg treated groups. In addition, the highest dose induced fetal malformations, mainly represented by hydrocephaly, extra-ribs, clubfeet and cleft lips.
