ABSTRACT
Objective To investigate influence of ulinastation in storage period on apoptosis of suspended erythrocyte.Methods RBCs were treated with saline (control group) and different doses of ulinastatin (5,000, 10,000 and 50,000 U/mL in group C1, C2 and C3, respectively).samples were detected when stored at 0,7,14,21,28,35 d,respectively.Indicators of corpuscular volume,phosphatidylserine extroversion rate and intracellular Ca2 +concentration were analyzed by flow cytometer.Results The phosphatidylserine (PS)-exposure levels of 4 groups started to increase on 14 day(P<0.05). Cells of the control group, group C1 and C2 began to shrink remarkably on day 21, while that of Group C3 on 28 day.The intracellular Ca2 +levels of the control group and group C1 started to increase significantly on day 35, (t=16.33,t=14.66,P<0.05).one Ca2 +levels of group C1,C2 and C3 increased on day 14.From 21 to 35 day, the intracellular Ca2 +levels of group C2 and C3 were no significant compared with control group.Conclusion During the storage period, suspended erythrocyteapoptosis increase with time prolonged, adding suitable amount of ulinastatin in stock solution can inhibit apoptosis in damage at some level.
