Effects of Blood and Crystalloid Cardioplegia on Cardiac Function at Organ and Cellular Levels During Hypothermic Cardiac Arrest

The present investigation was un-dertaken to compare the effects of cold crystalloid and blood cardiople-gia on the functional recovery of the heart; on Ca+ + binding and uptake, Ca+ +-ATPase of the sarcoplasmic reticulum (SR), and sarcolemmal (SL) ATPase; and on serum MB frac-tion of creatine kinase (MBCK) after one and a half hours of reperfusion following one hour of ischemic car-diac arrest in dog. This study was made also to determine if the func-tional changes are related to th
