The rat hearts were harvested and mounted on the Langendoff apparatus to perfuse with K-H buffer solution to estimate the leakage of enzymes of the myocardial tissue. Then they were arrested and stored in each preservation solution (4℃) for 8 hours. At the end of the storage period, the rat hearts were resumed and reperfused in Langendoff model. The water content and the leakage of enzymes of the myocardial tissue were measured.
