The 4th left rib was cut and a model of left coronary artery occlusion/release was carried outo Rats were divided randomly into 4 groups: control group without LCA occlusion (group A, n=6);I/R group(group B, n=6); ketamine(5mg.kg-1)+I/R group (group C, n=6); ketamine(10mg.kg-1)+I/R group(group D,n=6)o All rats in groups B, C , D were subjected to 30 minutes of LCA occlusion followed by 120minutes of reperfusion. Rats in group C and D were injected with 5mg.kg-1 and 10mg.kg-1 of ketamine before reperfusion, respectively. Significant electrocardiogram and color changes at the area at risk were considered indicative of successful coronary occlusion and reperfusionc Serum was exampled from left jugular vein at 30 minutes and 120 minutes during reperfusion to measure IL-6 and TNF- level by ELISA measurements. After reperfusion of 120 minutes, the heart was removed and the cardiac apex was exampled with snap-frozen in liquid nitrogen and stored at -70 C .
