title: [Age specificity of lipid fluidity in the sarcoplasmic reticulum of the rat heart].
abstract: The lipid fluidity in heart sarcoplasmic reticulum membranes prepared from adult (12 mo.) and old (24 mo.) rats has been measured by the fluorescence probe (DPPH) and spin probe (5NS) methods at 22 and 37 degrees C. The lipid fluidity in the old rat membranes is higher than that in the adult rat ones. It has been suggested that this difference is caused by age lowering in reliability of membrane fluidity stabilization systems.
