Abstract:

To explore the expression of p38MAPK on H9N2-SIV induced acute lung injury(ALI) in mice,180 seven weeks old SPF BALB/c female mice were randomly divided into H9N2-SIV infected group(infected group),H9N2-SIV infected +SB203580 group(SB group) and control group,and clinical observation,pathological histology observation of lung,and the determination of distribution and expression of phospho-p38MAPK in lung were conducted on the 2nd,4th,6th,day and the 8th day post infection(p.i.) respectively. We found that the mice of infection group and SB group showed clinically apparent symptoms,compared with control group,the expression of phospho-p38MAPK protein in infection group was stronger with significant difference(P<0.05) on the 2nd day p.i.,it reached to the top with extremely significant difference(P<0.01) on the 6th day p.i. SB203580 can inhibits phosphorylated p38MAPK in lung tissue,lung injury of SB group mice is less than that of infection group. It indicates that p38MAPK can be activated by H9N2-SIV and participate in the occurrence and development of ALI,SB203580 can lighten pathological injury of lung in ALI.
