To explore the influence of aprotinin on the mRNA expression of P-selectin and ICAM-1 in lung tissue after ischemic reperfusion.Methods Thirty New Zealand white rabbits were randomly divided into 3 groups:control group,LPD group and aprotinin group.In situ rabbit lung preservation model was established.In control group,the left lower lung lobe was stored at 10℃ in a specially made lung preservation container for 2 hours and reperfused for another 2 hours.In LPD group and aprotinin group,the left lower lobe was perfused with LPD solution or aprotinin containing LPD solution,respectively,after left lung hilus was clamped.The other procedures were the same as those in control group.The lung tissue was harvested at different time intervals including preclamping lung hilus,2 hours after clamping and 2 hours after reperfusion.The mRNA expression of ICAM-1 and P-selectin in the lung tissue was detected with RT-PCR technique.Results The contents of mRNA of P-selectin at 2 hours after reperfusion in control group and LPD group were significant higher than pre-ischemia and 2 hours after champing the left lung hilus.There was no such significant difference in aprotinin group.The mRNA expression of P-selectin in aprotinin group at 2 hours after reperfusion was significantly lower than that in control group and LPD group.The ICAM-1 mRNA expression at 2 hours after Ischemia and 2 hours after reperfusion in control group and LPD group was significantly higher than the pre-ischemia and its was significantly higher than that in aprotinin group.Conclusion Aprotinin can inhibit the upregulation of the mRNA expression of P selectin and ICAM-1 after ischemia reperfusion in the lung tissue,so the addition of aprotinin in LPD solution may reduce the ischemia reperfusion injury in lung tissue.5 refs,1 tab. 展开更多
