Abstract

The aim of the work is to study the activity of lipoperoxidation processes and antioxidant protection system in the umbilical cord blood of newborns from CMV-seropositive women with exacerbation of infection in the third trimester of pregnancy. Lipid peroxidation activity and antioxidant status in 30 newborns from CMV-seropositive women with exacerbation of infection in the third trimester of pregnancy and in 25 from CMV-seronegative women were studied. Erythrocytes were used to determine the products of oxidative modification of lipids; antioxidant status was evaluated in the blood plasma of the umbilical vein. The content of TBK-active products was determined by fluorometric method, lysophosphatidylcholine by thin-layer chromatography, arachidonic acid by gas-liquid chromatography. Antioxidant status was assessed by α-tocopherol content and superoxide dismutase activity. Registration of optical densities and fluorescence was carried out using a spectrofluorometer. The study found an increase in the content of red blood cells of the umbilical cord of newborns from CMV-seropositive women with an exacerbation of infection in the third trimester of pregnancy of TAC-active products in 2.1 times (р˂0.001), of lysophosphatidylcholine in 1.9 times (р˂0.001) and of arachidonic acid in 1.5 times (р˂0.001). The antioxidant status of umbilical cord blood was characterized by 1.5 times decrease in α-tocopherol (p<0.01) and 1.3 times decrease in superoxide dismutase activity (р˂0.001) compared with similar indices in the group of newborns from CMV-seronegative women. The results of the study show that the exacerbation of cytomegalovirus infection in the third trimester of pregnancy is accompanied by the development of oxidative stress and tension in the system of antioxidant protection in the blood of the umbilical cord of newborns due to increased consumption of α-tocopherol and suppression of superoxide dismutase activity.
