The first part consists of three experiments:(1) The rings were incubated in KH, 20, 50 mmol/L 〓 for 1 house, relaxation in response to the EDHF stimuli A23187 in 30nmol/L U46619-induced preconrtaction in the presence of 7 μ mol/L indomethacin, a cyclooxygenase inhibitor, 300μmol/L LNNA, a nitric oxide biosyhnthesis inhibitor, and 1mmol/L tetraethylammonium , a 〓 blocker, or 3 μmol/L glibenclamide , a 〓 blocker, was compared with the control;(2) After the arteries were incubated in KH, UW solution or HTK solution at 4℃ for 4 hours, endothelium-derived relaxation (percentage of 30nmol/L U46619 precontraction) was induced by A23187 in the present of 7 μmol/L indomethacir and 300μmol/L LNNA;(3) After incubation with KH, UW solution and STH (either at 37℃ in oxygenated organ chamber or at 4℃ in a refrigerator for 4 hours), endothelium-derived relaxation (percentage of 30nmol/L U46619 precontraction) was induced by A23187 in the present of 7 μ mol/L indomethacin and 300 μmol/L LNNA.

第一部分研究结果：（1）单纯浸泡于KH的冠状动脉A23187能引发66.67％的血管舒张反应，经TEA及20mmol／L、50mmol／L钾离子作用后，血管舒张反应程度显著降低，但经GBM作用后改变不明显；（2）与保存于KH的冠状动脉相比，A23187引发的血管舒张反应程度，保存于UW液的明显下降，保存于HTK液的无明显变化；（3）在37℃条件下，血管环浸泡于STH出现缓慢轻微的舒张反应，浸泡于UW液初期出现短暂收缩反应，但此后主要以舒张为主：在37℃条件下，血管经UW液保存后，U46619引发的收缩反应程度降低；不论在37℃或4℃条件下，A23187引发的血管舒张反应，经UW液保存后明显下降，但用STH保存后变化不明显。
