ABSTRACT

Objective To investigate the effect of different adjuvants and challengemethods on asthma mice′s lung inflammation . Methods BALB/c mice were sensitized with ovalbumin in aluminium hydroxide or alum adjuvant .After 7 days challenges ,choose the proper adjuvant with intranasal or atomized to prepare mice asthma model .Count and classify the white blood cells (WBC) in bronchoalveolar lavage fluid(BALF) ,observe the peribronchial and perivascular inflammation .Results Compare the WBC and eos-nophils in BALF ,the alum group are higher than aluminum hydroxide group(P0 .05) .10 days after the last challenge ,the inflammation fade sharply ,and the corresponding result occured in the lung inflammation .Conclusion In establishing asthma model ,alum is better than aluminum hydroxide ,atomization is better than intranasal .Inflammation will fade after stop atomization a period of time .
