[The seasonal aspects in activity of antioxidate enzymes in delivery woman inhabiting in the north].

The activity of super oxide dismutase (S), glutathione peroxidase (P), glutathione reductase (R) were analyzed 4 times during delivery (24 hour before partum, at start of the partu, immediately postpartum, and in 24 hours postpartum) in two populations of women inhabiting at 62 degrees NC (55 cases) and 69 degrees NC (40 cases) with normal delivery in January, March, June, and October. It was shown that physiological delivery did not play any significant role in S and P activity, and for these enzymes essential was the seasonal level of lipid peroxidation in North inhabitants. Activity of R in January and March was significantly lowered to the end of childbirth. Most Northern delivery women seem to have limited reserves in antioxidant enzymes function.
