ABSTRACT
AIM: To clarify the possible mechanism of decrease in coronary flow (CF) after long-term hypothermic storage of the isolated rat hearts. METHODS: The isolated rat hearts preserved in different solutions (SDMC-1,2 S., Stanford S., Collin's S.) at 0℃ for 8 hours were reperfused with 5-hydroxytryptamine (5-HT)(10 -4 mmol/L) and adenosine(Ade)(5 mmol/L) respectively, and the coronary flow(CF), coronary vascular resistance(CVR) and the weight of heart were measured before and after reperfusion. RESULTS: CF decreased while CVR increased in all groups after storage-reperfusion. When endothelium-dependent vasodilator (5-HT) was used, CF in SDMC-2 group was highly increased and CVR decreased. Whereas CF was significantly decreased and CVR increased in Collin's group( P
