title: Study on erythrocyte membrane fluidity by laser Raman spectroscopy.
abstract: Differences between patients with cirrhosis of liver, nephrotic syndrome, coronary heart disease and normal subjects in laser Raman spectra of erythrocyte membranes have been found. In regions of 1000-1140 cm-1 and 2840-3000 cm-1, the ratios I1130/I1080 and I2890/I2850 in patient membranes are higher than those in normal ones respectively. These results mean that erythrocyte membrane fluidity of these patients is reduced. This reduction may be attributed to the possibility that erythrocyte membrane of patients get more cholesterol from their plasma and resulted in the modification of the ratio of cholesterol/phospholipids in the membranes.
