ABSTRACT
AIM:
To investigate the expression of iNOS in the lung of HPS rats treated with tumor necrosis factor-? monoclonal antibody(TNF-?-McAb) and to investigate the therapeutic mechanism of TNF-?-McAb on hepatopulmonary syndrome.METHODS:
Male Sprague-Dawley rats,weighing(250?25)g,were randomized to sham operation group,common bile duct ligation(CBDL) group and CBDL+TNF-? McAb treatment group.Histopathological changes of the lung tissue were evaluated by hematoxylin and eosin staining.The mRNA expression of iNOS in the lungs of hepatopulmonary rats was examined by RT-PCR,while the changes of iNOS in the protein level were evaluated by immunohistochemistry and Western blotting.RESULTS:
The inflammatory responses in the CBDL rats treated with TNF-?-McAb decreased than that in CBDL group.Compared to CBDL group,the distribution of iNOS protein and the mRNA expressions in the lung tissue in TNF-?-McAb group were inhibited.CONCLUSION:
TNF-?-McAb inhibits the expression of iNOS and plays a role in the treatment of HPS.
