Superoxide anion, hydrogen peroxide, hydroxyl radical, SOD and catalase activity were measured.Results: Sal (1, 10, 100 μmol/L) inhibited generation of ROS of rat neutrophils during respiratory burst induced by formyl-methionyleucylphenylalanine (FMLP) and phorbol myristate acetate (PMA) dosedependently, and it enhanced SOD and catalase activities.Conclusion: Sal may inhibit generation of ROS and enhance activity of anti-oxidant enzymes of neutrophils to reduce oxidative injury to tissues.展开更多
