Abstract:
Objective To observe the expressions of stem cell factor(SCF) and macrophage colony-stimulating factor(M-CSF) in bronchoaveolar lavage fluid(BALF) of asthmatic mouse,and the effect of bacillus calmette-guerin(BCG) intervention on them.Methods Thirty Kunming rats were randomly divided into asthmatic group,BCG intervention group and control group,each group had 10 rats.Mice were sensitized and challenged with ovalbumin (OVA) to establish asthmatic model.Asthmatic mice were injected intradermally with BCG on 7,3,1 d before sensitization.After 24 h of last challenge,BALF were collected.The total cells and eosinophils(EOS) were counted in the BALF.The SCF and M-CSF levels of BALF were determined by enzyme-linked immunosorbent assay(ELISA).Results The number of total cells and EOS [(27.06?4.25)?107 L-1,(7.58?1.30)?107 L-1]in BALF in asthmatic mice were more than those in control group[(4.93?1.43)?107 L-1,0](Pa0.05).The M-CSF level also increased noticeably in asthmatic mice[(204.30?10.39) ng/L] compared with the control group[(181.33?8.63) ng/L](P
