Four types of phosphatidae of erythrocyte membrance including PC, PF, PS, and PI were determined in 38 patients with diabetes millitus and 35 normal subjects as control. At the same time plasma lipid peroxides (LPO). activity of superoxide dismutase (SOD) in blood cells and activity of glutathine peroxidase (GSHPX) of the blood were also investigated. The reuslts showed PC, PE, PS, and PI in erythrocyte membrane were much lower and plasma LPO were much higher blood cells and activity of GSHPX in the whole blood were significantly lower in patient group than in control. The relationships betwee...
