Abstract
Objective To explore the influence of ulinastatin combined with methylprednisolone on aquaporin l(AQP 1) and tumor necrosis factor-alpha(TNF-α) in serum when ischemia reperfusion injury occured in rats. Methods 40 Wistar rats were ran domly devided into 5 groups(n =8):normal control group, model control group, methylprednisolone group(30 mg/kg), ulinastatin group(50 000 U/kg) and combination group[ulinastatin(50 000 U/kg) combined with methylperdnisolone(30 mg/kg)]. Levels of AQP l and TNF-α in serum were detected by enzyme linked immunosorbent assay(ELISA) ;Protein contents in bronchoalveolar lavage fluid were assayed by Commassie blue staining; Wet and dry mass were measured by scale and pulmonary morphological changes were observed by optical microscope. Results Compared with model control group, serum concentration of AQP l was significantly increased and that of TNF-α decreased in ulinastatin group and methylprednisolone group, especially in combination group(P<0.01) ;Protein contents in bronchoalveolar lavage fluid and wet/dry mass ratios were both markedly reduced in ulinastatin,methylprednisolone and combination groups(P<0.01). Conclusion Ulinastatin combined with methylprednisolone administration has better therapeutic effects on acute lung injury caused by ischemia reperfusion in rats, which mechanism probably correlated with increasing level of serum AQP l and decreasing that of TNF-α.关键词
