3277899-3	1988	Recent evidence demonstrates that free radical scavenging agents such as superoxide dismutase (SOD) + catalase, N-2-mercaptopropionylglycine, and allopurinol, administered prior to coronary artery occlusion, significantly enhance recovery of regional contractile function of the stunned, previously ischemic tissue.	radical	39-46	catalase	Homo sapiens	102-110	
14718647-7	2004	When cells were prelabeled with N-acetyl-cysteine (NAC), a substrate for glutathione synthesis, and catalase (CAT), the oxygen free radical scavenger, a significant reduction in cytogenetic damage was observed.	radical	132-139	catalase	Homo sapiens	100-108
