Rat thoracic aorta can be cold-preserved without any change in vascular reactivity

Abstract

It is important to preserve vascular functions of isolated blood vessel for productivity of both organ transplantation and pharmacological and physiological research. Thus it is possible to investigate long-term effect of drugs, increase sample number taken from the same animal and study on human blood vessel. The aim of this study was, therefore, to determine whether vascular smooth muscle and endothelial cell function could be preserved in thoracic aorta after storage in Krebs-bicarbonate solution at 4°C. Vascular reactivity has been evaluated in rat thoracic aortic rings; either fresh isolated or preserved in Krebs-bicarbonate solution at 4° C for 1 or 15 hour. Endothelium-dependent relaxation responses were evaluated by acetylcholine (10-9-10-5 M), after precontraction with phenylephrine (10-6 M) and endothelium-independent relaxations were obtained by nitroglycerine (10-9-10-4 M) following U46619-induced precontraction. There were no statistically significant differences in contractile and relaxant responses between all groups. These results demonstrated that it is possible to provide ideal condition to preserve vascular reactivity of isolated blood vessel by using appropriate storage solution and period depend on vessel type and suggested that the ideal conditions can be achieved by storing rat thoracic aortic rings in Krebs-bicarbonate solution at 4°C for up to 15 hour to preserve contractile and relaxant responses of both endothelium and vascular smooth muscle.
