the protective effect of alpha-tocopherylacetate , tocopherilquinones and partially of alpha-tocopherol is due to a stabilizing effect of these compounds on sarcoplasmic reticulum membranes , registered by a decrease of fluidity of membrane lipid bilayer ( probed by nitroxile radical tempo ) and by a decrease of its passive permeability for ca2+ .
