Influence of Chronic Alcohol Intake on Intestinal Taurine and Antipyrine Transport in Pregnant Rats

1998

Taurine is a nonessential amino acid that plays a critical role in development. However, biosynthetic capacity is almost negligible in the fetus and must be supplied by the mother. Therefore, when maternal taurine status is depressed during gestation, fetal tissue taurine concentrations can also be compromised. In the present study, the effect of chronic alcohol intake on the intestinal transport of taurine during pregnancy has been investigated by an in vitro technique that allows measurement of the unidirectional influx of the amino acid across the intact rat mid jejunum. The influence of alcohol intake on the passive component of the intestinal transport was also investigated with antipy…
