摘      要：Using electron spin resonance (ESR) spin labeling technique, we have studied the conformation of sulfhydryl groups(-SH) binding sites in membrane proteins and membrane fluidity of red blood cells (RBCs) from two groups of patients with anemia of chronic renal failure (ACRF). One of the groups is composed of patients who were untreated with recombinant human erythropoietin(r-HuEPO), and the other is composed of patients who were treated with r-HuEPO. The results indicated: 1) the conformation of SH group binding site in RBC membrane proteins from former group was different from those of health people. 2)the fluidity in the region near the surface of RBC membrane from former group was lower than those of healthy people. 3) However, the above biophysical properties of RBC membrane from later group were normal. We concluded that RBC membrane in patients with ACRF was abnormal, and the treatment of r-HuEPO may promote the production of normal RBCs, thus ameliorate the biophysical properties of RBCs from the patients with ACRF.
