or-Adrenergic Receptors and 45 Ca 2 + Efflux in Arteries From Deoxycorticosterone Acetate Hypertensive Rats

Increased vascular sensitivity to catecholamines characterizes mineralocorticoid hypertension. The present study investigated three possible sites that may account for this abnormality: agonist affinity, Ca release from intracellular stores, and Ca sensitivity of the contractile proteins. Adult male Sprague-Dawley rats underwent uninephrectomy and were… (More)
