    Abstract:
    The objective this study was to observe the morphological changes in developing rat embryo exposed to alcohol in utero. Virgin female Wistar rats in experimental group (n=15) were given 20% (v/v) alcohol two weeks before mating and throughout the gestational period through oral route. The controls (n=15) were also maintained and were given the tap water. On gestational day 15 (GD15) and 19 (GD19), five rats from each group were sacrificed by cervical dislocation and the abdomen was incised to expose the uterine horn. The number of implantation sites and resorptions were counted and recorded. The body weight and length of the fetuses were also recorded. The litter size and body weight of the newborn were also recorded at the time of birth from the remaining dam. The incidence of resorption was higher in alcohol treated group than in control which was found to be 25% and 8.7% at days 15 and 19 respectively. The body weight and length of fetuses were found to be decreased and was significant at GD15 (p<0.001 for weight and p<0.05 for length). Similarly, the litter size and body weight of newborn were also found to be decreased significantly (p<0.05 for litter size and p<0.01 for body weight). The present study shows that the maternal consumption of alcohol during pregnancy has adverse effect on fetal viability and development of growing embryo.
