LPO–Antioxidant Defense System in Newborns and Women Drinking Small Amounts of Alcohol During Pregnancy

We studied the effects of consumption of low-alcohol drinks (no more than 2 doses) during pregnancy on the state of LPO-antioxidant defense system and glutathione level in the blood serum and erythrocytes of pregnant women and newborns. It was found that even single alcohol intake was followed by the development of oxidative stress in women and newborns. In pregnant women, the decrease in reduced glutathione content and glutathione reductase activity associated with increased level of oxidized glutathione and glutathione transferase activity were typical changes. In newborns, the decrease in reduced glutathione concentration was accompanied by a decrease in glutathione reductase, glutathione transferase, and glutathione peroxidase activities. It should be emphasized that even small alcohol doses produce delayed negative effects on metabolism of the mother and newborns.
