But compared with asphyxia group,the change in morphology of HK-2 was obviously improved,and the leakage rate of LDH decreased and the cell viability increased in group of pretreatment with EPO in a dose-dependent manner except the group of 1 IU/mL.

• 而与窒息组比较；除EPO1IU/mL组外；EPO组细胞形态明显得到改善；LDH漏出率降低；细胞存活增加；差异具有显著性(P<0.；05)；且具有剂量依赖性。
