Evaluation of total antioxidant power of plasma in biomass smoke exposed COPD patients

摘要

The present study was carried out to analyse the total antioxidant power of plasma in biomass smoke exposed COPD patients and matched controls. A total of 48 biomass smoke exposed COPD patients and 29 matched controls were assessed. FRAP (ferric reducing ability of plasma) assay was used to measure the total antioxidant ability of plasma. The mean age of COPD patients was 56.062±1.754 years and that of control subjects 56.793±2.751 years. Markedly significant difference (p<0.001) was observed in the mean FRAP value of biomass smoke exposed COPD patients (361.900±9.056) as compared to controls (727.210±12.976). Mean value of FRAP in vegetarians and alcohol consuming biomass smoke exposed COPD patients showed no significant difference (p>0.05) as compared to the non-vegetarians and abstainers.
