Summary Maternal ethanol consumption during pregnancy has been demonstrated to result in deformity of the developing fetus. This condition has been labeled Fetal Alcohol Syndrome (FAS) and is characterized by facial deformity, neural defects, small birth size, and other malformations. Ethanol has been shown to be highly teratogenic in most of the animal models (rat, mouse, sheep and chick embryo) that have been studied. The current research was an attempt to establish the effect of ethanol on the processes of DNA replication by studying thymidine incorporation into chick neural tissue. Firstly, it was determined if ethanol effected the rate of thymidine incorporation into DNA and if so, was it dose related? Secondaly, if ethanol did effect thymidine incorporation into DNA, which step of incorporation was affected? Results demonstrate that ethanol adversely influences chick embryo development. Ethanol exposure in-ovo resulted in a reduction in viability, embryo weight and brain weight. A reduction in the amount of thymidine incorporated into DNA has also been demonstrated. Further study is required to determine at which step in the DNA synthesis does ethanol exhibit its influence.
