Effect of indomethacin on alcohol-induced morphological anomalies in mice
The purpose of the present study was 1) to examine the effect of indomethacin (INDO), a prostaglandin synthesis inhibitor, on alcohol-induced growth and morphological impairment in C57BL/6J mice (Study 1) and 2) to determine if INDO crosses the placenta (Study 2). On day 10 of gestation, mice were injected (s.c.) acutely with either 0, 5, 10, or 20 mg/kg INDO, followed one hour later by alcohol (5.8 g/kg orally) or isocaloric sucrose. Fetuses were removed on day 19 of pregnancy, weighed, and examined for anomalous development. As expected, Study 1 demonstrated that maternal alcohol treatment decreased fetal weight and increased the number of fetuses with birth defects. INDO alone decreased fetal weight but did not affect morphologic development. More importantly, INDO antagonized alcohol-induced birth defects, but only at the highest dose. The results of Study 2 suggest that the relative ineffectiveness of INDO may be related to its inability to readily cross the placenta. Since high doses of INDO also caused maternal toxicity, the usefulness of this compound in future studies of this type was questioned. 22 references, 4 tables.
