ESR STUDIES ON THE ANTIOXIDATION PROPERTIES OF SERA AND ERYTHROCYTES FROM PATIENTS WITH ANEMIA OF CHRONIC RENAL FAIL
慢性肾衰病人血清和红细胞抗氧化能力的ESR研究

Using electron spin resonance (ESR) spin trapping technique, we have studied the effects of sera and red blood cells from healthy people and patients with chronic renal failure on oxygen free radicals produced in xanthine xanthine oxidase system. Experimental results showed that: (1) sera and red blood cells from healthy people could both scavenge superoxide anion (O2) more effectively than sera and red blood cells from patients with chronic renal failure; (2) sera from healthy people could change (O2) to hydroxyl radical (OH) more easily than sera from the patients. The differences were significant by statistics two tail's t-test.
