Efficacy of a Low Dose of Estrogen on Antioxidant Defenses and Heart Rate Variability
Figure 1
(a) Hydrogen peroxide concentration in myocardium (in nmol/g tissue) and (b) superoxide anion concentration in myocardium (in mmol/mg protein). Data are mean ± SD. per group. Ovariectomized group = Ovx; ovariectomized group treated for 21 days with low dose of estrogen = LE; ovariectomized group treated for 21 days with high dose of estrogen = HE. versus Ovx.
