We examined the contribution of endogenous prostanoids to baroreceptor activation in chronic renal hypertension. Baroreceptor activity was recorded from the vascularly isolated carotid sinus during slow ramp increases in pressure in rabbits anesthetized with pentothal and chloralose. Mean arterial pressure averaged 133 +/- 4 mmHg in hypertensive rabbits(More)
The purpose of this study was to examine the ability of baroreceptors of renal hypertensive rabbits to reset rapidly during acute changes in arterial pressure. The carotid sinus (CS) was vascularly isolated and baroreceptor activity was recorded during slow ramp increases in CS pressure in hypertensive (one-kidney, one wrap; 127 +/- 3 mm Hg) and(More)
In anesthetized rats with sinoaortic denervation, intracerebroventricular (icv) injection of atrial natriuretic peptide (ANP) resulted in decreased mean arterial blood pressure (MAP), heart rate (HR), and renal sympathetic nerve activity (RSNA) (depressor effects), whereas icv angiotensin II (ANG II) produced increases in these variables (pressor effects).(More)
Salvianolate has been reported to possess protective properties. However, its specific mechanisms have yet to be identified. Our study aimed to identify the molecular mechanism of antioxidative stress function of salvianolate on rat ischemia and reperfusion brain tissues. Rats were randomly distributed into three experimental groups: sham, model and(More)
AIM To study whether there is a high affinity receptor for advanced glycosylation end product (AGEP) on thoracic aorta smooth muscle cells (ASMC) and to test effect of diltiazem on elevation of cytosolic free calcium induced by AGEP. METHODS Interactions of AGEP-bovine serum albumin (BSA) with ASMC were studied with radioligand binding assay and cytosolic(More)
Stroke remains a worldwide health problem. Salvianolate exerts a protective effect in various mi-crocirculatory disturbance-related diseases, but studies of the mechanisms underlying its protective action have mainly focused on the myocardium, whereas little research has been carried out in brain tissue following ischemia-reperfusion. We assessed the(More)
