[Effect of antianginal agents on nicotinamide coenzyme content and NAD-dependent dehydrogenase activity]

Intraperitoneal administration of pituitrin (2 units/kg) decreases the number of oxidized forms of nicotinamide coenzymes in the rat myocardium and raises the level of reduced forms and LDH activity. Nitroglycerin (1 mg/kg) prevents pituitrin-induced changes in the content of coenzymes and in LDH activity.
