Uterine hydrogen peroxide concentrations and peroxidase activities in the estrous cycle and perimaturation period of mice.
The concentrations of hydrogen peroxide (H2O2) and peroxidase activity (PA) were measured in mouse uterus during the perimaturation period (4-8 weeks of age) and the estrous cycle. The onset of maturation was accompanied by a spurt in PA but not in H2O2. Neither H2O2 nor PA varied significantly during the estrous cycle. These results differ from those reported in the rat where positive correlations for both with the estrogen state of the uterus were observed.
