because sarcolemmal ca2+-pump is involved in the efflux of ca2+ from the cell , this study was undertaken to examine the effects of oxygen free radicals on sarcolemmal atp-dependent ca2+ accumulation and ca2+-stimulated mg2+-dependent adenosinetriphosphatase ( atpase ) activities as well as lipid peroxidation of membrane phospholipids .
