title: [The state of lipid peroxidation and enzymes of calcium transport system in sarcoplasmic reticulum of ischemic myocardium].
abstract: In 30 experiments on mongrel dog hearts it was shown that 30 min of total ischemia (37 degrees C) followed by accumulation of MDA in the SR membranes and decrease of their Ca2+-uptake, but had no effect on activity Ca2+-ATPase. After 60-120 min ischemia marked a decrease of Ca2+-uptake and activity Ca2+-ATPase took place, MDA content remained at the increased level. The results show that lipid peroxidation take part in the increase of the permeability of SR membranes for Ca2+ and inhibiting of Ca2+-ATPase.
