Activation of Protein Kinase C Contributes to the Isoflurane-Induced Improvement of Functional and Metabolic Recovery in Isolated Ischemic Rat Hearts

In Brief Isoflurane enhances myocardial functional recovery and improves energy levels after ischemia. We sought to determine whether isoflurane-induced cardioprotection is mediated by protein kinase C (PKC). The Langendorff model was used, and isolated perfused rat hearts were separated into untreated, isoflurane, chelerythrine (PKC inhibitor) plus isoflurane, and chelerythrine groups. All hearts were subjected to treatment before ischemia,...
