Why the study?
Does reserpine pretreatment alter the responsiveness of cerebral and mesenteric arteries to vasoactive agents in dogs?
Population
Dogs (cerebral and mesenteric arteries isolated from control and reserpine-treated dogs)
Comparison
Pretreatment with reserpine for 20 to 24 hours… vs Control dogs (no reserpine pretreatment)
Design
Preclinical

No immediate clinical implications; leaves open differential noradrenergic mechanisms across vascular beds in humans.
Does reserpine pretreatment alter the responsiveness of cerebral and mesenteric arteries to vasoactive agents in dogs?
Reserpine pretreatment differentially affects the responsiveness of dog cerebral and mesenteric arteries to vasoactive agents, suggesting tyramine and nicotine do not release sufficient noradrenaline to cause contraction in cerebral arteries.
Hayashi et al. (1980) studied this question.
