The teratogenic effects of ethanol include malformations of the cardiovascular system, which may be abrogated by multivitamin therapy. Chick cardiomyocytes in micromass culture were treated with ethanol alone or with supplementation with folate or vitamin C. Ethanol alone caused a loss of cell viability and differentiation (beating) whereas those cells treated in addition with vitamins were comparable to the control. Chick embryos were injected on day 3 of incubation with PBS, ethanol alone or with additional vitamin C or folic acid. On day 9 embryos were examined for viability, growth retardation and gross malformation and the hearts were processed for histology. Results showed that ethanol significantly decreased survival of embryos or caused growth retardation and gross malformation (p<0.05). Embryos incubated with addition of vitamin C or folic acid were comparable to the control. Data obtained in this study suggest that supplementation with vitamin C or folic acid during pregnancy may prevent defects in heart development brought about by ethanol.
