Coronary circulatory failure and thromboxane A2 release during coronary occlusion and reperfusion in anaesthetised dogs.

abstract：OBJECTIVE:We investigated the influence of experimental hyperlipidemia on the formation of cardiac NO, superoxide, and peroxynitrite (ONOO(-)) in rat hearts. METHODS:Wistar rats were fed 2% cholesterol-enriched diet or normal diet for 8 weeks. Separate groups of normal and hyperlipidemic rats were injected twice intra...
