Abstract

BACKGROUND AND AIM: Structural changes in the large resistance vessels in hypertension amplify resistance responses in vitro, but their role in vivo has been controversial. To resolve this matter, we re-examined earlier data in Page hypertension. METHODS: Total peripheral resistance (TPR) and total peripheral conductance (TPC) responsiveness were compared in hypertensive and normotensive rabbits, 5 weeks after bilateral renal cellophane wrapping or sham operation. The rabbits were studied with effectors intact; during ganglionic blockade; during neurohumoral blockade (NHB). For each condition extended scaled dose (ScD)-TPC and TPR curves were derived from individual dose-response curves to t..
