Hemodynamic changes that accompany the pressor response to propranolol in urethane anesthetized rats subjected to alpha-blockade.

Abstract

It has been shown that a paradoxical pressor response to a beta-blocker occurs in rats given an alpha-blocker. The dual-isotope microsphere technique was used to investigate the hemodynamic changes that accompany the pressor response to propranolol in phentolamine-treated, urethane-anesthetized rats. Rats were divided into four groups (n = 8 per group… (More)
