The role of tumor necrosis factor-alpha was investigated in an anaesthetized rat model of coronary artery ligation (60 min) and reperfusion (MI/R). Sham-occluded rats (sham MI/R) were used as controls. Survival rate, myocardial necrosis, myocardial myeloperoxidase activity, serum creatinine kinase activity and serum and macrophage tumor necrosis factor-alpha were studied. Ischaemia-reperfusion injury significantly reduced survival rate (45%), produced marked myocardial injury, increased serum creatinine kinase activity and increased myocardial myeloperoxidase activity in the area-at-risk and in the necrotic area. Serum tumor necrosis factor-alpha was undetectable during the occlusion period, but increased significantly upon release of the coronary artery. At the end of reperfusion, macrophage tumor necrosis factor-alpha was also increased. Passive immunization with a hyperimmune serum containing antibodies against murine tumor necrosis factor-alpha significantly increased survival rate (80%), lowered myocardial necrosis, reduced the increase in serum creatinine kinase activity and decreased myeloperoxidase activity in the area-at-risk and in the necrotic area. These data are consistent with an involvement of tumor necrosis factor-alpha in myocardial ischaemia-reperfusion injury.
