Abstract :

The structural development of fetuses was altered when Dipterex was administered by diet to pregnant rats from days 6 through 15 of gestation. Major external and skeletal alterations occurred after consumption of 432 or 519 mg/kg body weight per day, only minor skeletal changes occurred in the 375 mg/kg dose group and the incidence of alterations in the 145 mg/kg dose group was not significantly different from that in the pair-fed controls. The malformations seen at the two highest doses did not result directly from the associated decrease in food consumed. Dipterex was not shown to have teratogenic potential when given for the same time span, once daily by gavage, even at levels that produced maternal lethality. Imidan was not teratogenic when similarly given, either by diet at concentrations that resulted in a 45% reduction in food consumption, or by gavage at dose levels that resulted in some maternal lethality. Data collected from pair-fed control females revealed that limitation of food consumption to 13--15 g/rat per day from days 6 through 15 of gestation did not result in increased fetal mortality or stunting. However, fetal weight was reduced slightly, and the incidence of minor skeletal changes was approximately three to four times that among fetuses of control dams that were not pair-fed.
