Differential Neuroprotection of Selective Estrogen Receptor Agonists against Autonomic Dysfunction and Ischemic Cell Death in
Permanent versus Reperfusion Injury

Cardiovascular responses to PPT (1 mg/kg) or 50% DMSO pretreatment (i.v.; 30 minutes) prior to MCAO. (a) Representative physiograph tracings of changes in arterial pressure and heart rate to phenylephrine injection (PE; 2.5 μg/mL). Graphs represent average changes in mean arterial pressure (MAP; (b)), heart rate (HR; (c)), and baroreceptor reflex sensitivity (BRS; (d)). The dashed lines represents the times at which the MCA was occluded. Each data point represents the mean ± S.E.M ( = 4–6/group), and *indicates significance () from baseline values.
