Abstract:
Three major systems participate in the control of the peripheral circulation: the renin-angiotensin, the arginine vasopressin (AVP) and the sympathetic nervous systems. These studies examined the roles of the AVP and the sympathetic nervous systems in the regulation of blood pressure at both the central and the peripheral level. Anatomical studies have revealed that hypothalamic neurons containing AVP extend to the nucleus tractus solitarius (NTS) in the medulla. Since the NTS is the primary site of termination of the afferent neurons of the baroreceptor reflex arc, it suggests that AVP may b

During exercise, local adrenergic blockade was produced by intracoronary injection of 1.0 mg phentolamine ( anon-specific alpha-antagonist) or .5 mp prazosin. Exercise significantly increased HR, LVP, dP/dt max, CFV, %SL and dL/dt (s)max. Neither alpha-antagonist produced

The morbidity of and the mortality from cardiac disease are higher in diabetic patients.
