Several recent studies have provided evidence that gonadal steroid hormones can exert acute (nongenomic) effects on both neural and vascular tissues. This study examines the acute effects of testosterone (T) on vascular reactivity of the rat thoracic…

We measured agonist-induced changes in the iliac artery blood flow velocity (IFV) independent of baroreflex-mediated compensatory mechanisms in chronically instrumented New Zealand White rabbits (n = 8). Animals were instrumented with a Doppler flow…

The influence of daily spontaneous running (DSR) on the sympathetic (SC) and parasympathetic components of the arterial baroreflex control of heart rate (HR) was examined in 16 female Long Evans rats [8 sedentary (SED) and 8 DSR]. After

We tested the hypothesis that reflex responses to mechanical [increase in left atrial pressure (LAP) 0-25 mmHg] and chemical stimulation [left atrial injection of phenylbiguanide (PBG), 0.5-10 mg/kg] of cardiopulmonary receptors are greater in female…

In rat thoracic aorta, contractile responses to arginine vasopressin (AVP) are twofold higher in females than in males. To determine the role of the endothelium in this phenomenon, the effects of endothelium removal and inhibition of nitric oxide…

Previously, we reported that, in the rat, pressor responsiveness to vasopressin (VP) is higher in males than in females during most phases of the estrous cycle. To explore the role of the vasculature in this phenomenon, we examined vascular…
