We developed a conscious, chronically instrumented, exercise-trained rat model and examined the time course of the training-induced alteration of baroreflex function in response to hypertensive conditions. Exercise-trained (ET) animals ran at 18 m.mi

The objective of this investigation was to test the hypothesis that naloxone directly activates alpha-2 adrenoceptors to cause depression of neurogenic tachycardia as suggested in an earlier investigation (Naloxone-Induced Bradycardia in Pithed Rats:

Earlier experiments performed in this laboratory have demonstrated that naloxone infusion (1 mg/kg/min i.v.) into conscious rats results in a bradycardia that has a peripheral component, is dependent on a certain level of sympathetic activity and is

It is evident that hypertension is associated with elevated endogenous opiates. This study was designed to examine the role of endogenous opiates in the development and/or maintenance of two-kidney renovascular hypertension and in baroreceptor reflex

Opioid peptides can modulate cardiovascular function both directly and by modifying specific responses. The action of opioids on baroreceptors was evaluated in anesthetized dogs. Baroreceptor responsiveness was determined by observing the peak heart

Angiotensin II, when given into the vertebral arteries, acts at the area postrema to augment central sympathetic vasomotor activity. The mechanism of action is unknown but recent evidence implicates an interaction with the opiate system. In dogs anes

The anteroventral part of the hypothalamus adjacent to the third ventricle (AV3V) has been implicated in electrolytic lesion studies as a site crucial to the development and maintenance of hypertension. Cryoblockade is known to alter synaptic and axo
