title: [Effect of phentolamine and anaprilin on the makeup and distribution of electrolytes in the myocardium].
abstract: Acute tests with rats demonstrated that the adrenoblocking agent phentolamine acts predominantly on the potassium level in the myocardium, raising its total, intra- and extra-cellular content. The effect of anapriline was mainly on sodium. Thyramine, which like adrenoblocking agents displays a catecholine-reducing effect, did not produce any similar changes in the potassium and sodium content.
