Popis: Chronic low dosage reserpine treatment significantly depressed the frequency-response curve to sympathetic nerve stimulation in the isolated perfused dog mesenteric and intestinal blood vessels. This neuronal depression was reversed by norepinephrine, indicating that chronic reserpine dosage fails to produce a drastic impairment of adrenergic nerve function. The dose-response curve to injected norepinephrine was not significantly altered, thus supersensitivity to norepinephrine following chronic reserpine treatment is not a common phenomenon in all vascular tissue. The pharmacological interaction of certain adrenergic agents with sympathetic neuronal and receptor mechanism appeared unaltered by reserpine.
