Estrogen Replacement Reduces Oxidative Stress in the Rostral Ventrolateral Medulla of Ovariectomized Rats
Cardiovascular changes in sham-operated and ovariectomized rats with vehicle or estrogen treatment for 4 weeks. (a) Representative original tracings of BP, HR, and RSNA in four groups. Maximum and background noise levels of RSNA were measured after rats were euthanized. Changes in MAP (b), HR (c), baseline RSNA (d), and NE in 24-h urine (e) were presented in four groups. Means ± SEM, /group, versus sham + vehicle, and versus OVX + vehicle.
