Influence of active and passive smoking at pregnancy on expression of an oxidizing stress

Objective: definition of indicators of system prooksidanty-antioxidants at active and passive smoking during pregnancy. Material and methods. On the basis of city clinic for women 39 pregnant women on the term of a gestation of 37 weeks are examined. Questioning, rapid test for identification of a kotinin in urine, determination of level of a malon dialdehyde (MDA) and also activities superoxide dismutases (SOD) and catalases is carried out to bloods of surveyed. Patients are divided into 3 groups: I-of 11 smoking pregnant women subject to II-13 to passive smoking at pregnancy, III-control group of 15 women. Results. At patients of I and II groups substantial increase of level MDA in blood serum is noted. Reliable decrease of the activity of SOD of erythrocytes in the I group and insignificant decrease of the activity in II is taped. The indicator of catalase/SOD was statistically higher at active smoking. Conclusion. Active and passive smoking at pregnancy leads to change in prooxidatic and antioxidatic systems.
