The microviscosity of erythrocyte membranes and muscle microsomes from age matched 6-week old control mice REJ 129 Dy/Dy, and mice with muscular dystrophy REJ 129 DY/DY has been estimated by measuring the fluorescence depolarization of perylene. There was no difference between the erythrocyte membranes. The muscle microsomes from dystrophic animals had about 20% lower values than the controls. The temperature dependence indicated that a transition occurs in both sets of muscle microsomes, but the transition temperature was lower in the dystrophic microsomes. Cholesterol, phospholipid and triglyceride analyses of the membranes showed no difference between the erythrocyte membranes. The largest difference in the muscle microsomes was a two-fold increase in cholesterol level found in the dystrophic microsomes. No simple correlation could be made between the lipid analysis and the microviscosity measurements. Since the change in microviscosity is found in membranes isolated from the tissue primarily affected by the dy gene, we suggest that the change in microviscosity may be important in the development of the disease.
