Fluidity of erythrocyte membranes from patients with Duchenne muscular dystrophy: studies in intact erythrocytes and in ghosts.

We have studied the alterations of fluidity in intact erythrocytes and in erythrocyte membranes from patients with Duchenne muscular dystrophy. The interest of this study was to comparison directly two types of results; these demonstrate an increase of fluidity in the erythrocytic membranes, no changes are present when the label is incorporated in intact erythrocytes. It might be inferred that hypotonic haemolysis removes components that are more weakly bound in Duchenne membranes, and that exert an immobilizing effect on the membrane lipids.

Progressive muscular dystrophy type Duchenne. I. Spin label studies on the physico-chemical state of erythrocyte membranes.

Electron spin resonance studies of erythrocyte membranes from patients with Duchenne muscular dystrophy exhibit changes in the physical state of lipids and proteins in membranes when compared to membranes from normal subjects. The results suggest that the alterations in membrane lipid-protein organization are present in this disease.

Progressive muscular dystrophy type Duchenne. II. Viscosity and resistence to erythrolytic compounds of erythrocyte membranes.

The transition temperature of erythrocyte ghosts of normal subjects is about 18-20 degrees C. We have studied the viscosity of erythrocyte ghosts of dystrophic children, showing that the transition shifts to lower temperatures (17-18 degrees C). After treatment with erythrocytic compounds like L-Lyso phosphatidyl-Choline dystrophic erythrocytes hemolize at lower Lysophosphatidyl-Choline concentration and at a greater extents than these of normal and carriers subjects.
