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。

Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.
