[Determination of serum antioxidant capacity after induced abortion].

Free radical oxidation processes are a cause of ageing, cancer, cataract, etc. Antioxidants are agents that are able to suppress these processes. They create a system that determines the antioxidant capacity (AOC) of living tissue. The effect of various drugs on this system is of importance. A PDK-1 diagnostic coulonometer, an AOC-measuring device, has been developed by the Polyclinic Research Department, KRC, Russian Academy of Sciences. Medical abortion with mifepriston and misoprostol does not change the blood level of AOC significantly. The maximum baseline value of AOC is observed in repeat pregnancy nulliparas.
