72-hour
3.Results: In ischemia group, the peaks of MPO activity and CINC conentration were 24 hour and 6 hour respectively after ischemia, which initially increased at 1 hour, In ischemia reperfusion group, the peaks of MPO activity and CINC conentration were 72 hour and 6 hour respectively after ischemia reperfusion, which initially increased at 6 hour and Ihour down to normal at 24hour respectively.
6.There is a 72-hour window of opportunity and it may be best to support regional teams on the ground.
7.The expression of BMP-2 in 48-hour group increased 2.1 fold and the expression of collagen type I in 72-hour group increased 1.6 fold compared to the control group(P<0.01).
9.The animals were sacrificed at 24. 48. 72hour under sterile circumstance. The blood samples were collected for analysis of serum amylase(AMY). phospholipase A2 (PLA2).
