Dehydration attenuates the increase in hindlimb blood flow produced by environmental heating (EH) in baboons. This study explored whether intravascular volume repletion alone was sufficient to remove this dehydration-induced attenuation. In six unane

Dehydration attenuates the increase in limb skin blood flow elicited by environmental heating (EH). This study sought to determine which of the two primary effects of dehydration, increased body fluid osmolality or decreased body fluid volume, was pr

Dehydration markedly attenuates the increase in hindlimb blood flow elicited by environmental heating (EH) in baboons. This study sought to determine the importance of gradually produced increases in body fluid osmolality and decreases in body fluid

This study, carried out in two parts, sought to determine the importance of vasopressin (VP), the renin-angiotensin system (RAS), and the sympathetic nervous system in the dehydration-produced attenuation of hindlimb (cutaneous) vasodilation during e

This study examined the influence of elevated skin temperature (Tsk) on the central thermoregulatory control of leg blood flow in five unanesthetized, chronically instrumented, resting baboons (Papio anubis and P. cynocephalus). In each experiment, m

Previous studies indicate that the heat stress-induced cutaneous vasodilation in baboons is attenuated during dehydration by mechanisms other than the well-known neurohumoral vasoconstrictor mechanisms. Therefore, this study sought to determine wheth

The cutaneous vasodilation and renal vasoconstriction in baboons during environmental heating (EH) appear to be produced predominantly by sympathetic vasoconstrictor withdrawal and activation of the renin-angiotensin system, respectively. Since these

The characteristics and control of the increase in plasma renin activity (PRA) during environmental heating (EH) were determined in 12 unanesthetized, chronically catheterized baboons. Each EH experiment consisted of a 1.5- to 4-h exposure to an ambi

The mechanisms involved in producing intestinal vasoconstriction during a hyperthermia-producing intestinal vasoconstriction during a hyperthermia-producing environmental heat stress are unknown. Five conscious baboons (Papio anubis), each with chron

The involvement of changes in sympathetic activity, changes in cardiac efferent vagal activity, and nonautonomic mechanisms in producing the rise in heart rate (HR) during heat stress-induced hyperthermia was studied in seven unanesthetized, chronica
