The effect of ethanol upon early development in mice and rats. I. In vivo effect upon preimplantation and early postimplantation stages.

The preimplantation and early postimplantation effect of chronic alcohol consumption (at least a month before mating and during pregnancy until killing) and of acute ethanol intoxication during the preimplantation period (i.v. injection of ethanol) was studied on albino rats (Wistar) and albino mice (RAP). The main results were as follows: Chronic alcoholization. Rats: significant retardation of preimplantation development and in early postimplantation stages; a tendency of lowering of the mean litter size. Mice: significant increase of the number of preimplantation pathological forms; a tendency of lowering of the litter size. Pathological changes show, both in rats and mice, an obvious "litter effect.' Acute ethanol intoxication. Rats: significant retardation in some litters, normal or even advanced development in others. This effect differs from the previously reported effect of acute ethanol intoxication during early postimplantation stages. The results obtained attest the prenatal noxious effect of chronic ethanol consumption in both species used and of acute ethanol intoxication during preimplantation development upon early postimplantation development in rats. Within the limits of extrapolation possibilities, they represent a risk signal for other species (including human).[1]
