title: [The effect of total ischemia on the Ca2+-transporting activity of the sarcoplasmic reticulum of the rat myocardium].
abstract: Different caffeine and calcium concentrations have been studied for their influence on Ca2(+)-pumping function of sarcoplasmic reticulum in a homogenate from control and ischemic rat myocardium. Ca2(+)-transporting system of sarcoplasmic reticulum terminal cisternae membranes from the ischemic myocardium was found to be more sensitive to Ca2+ and caffeine action, inhibiting Ca2+ uptake velocity, as compared to control. This may be one of causes leading to the contractibility disorder under myocardium ischemia.
