Abstract:
Objective To investigate whether the spores from mushroom antigen can cause the allergic pneumonia and manufacture allergic animal model in the C57BL/_6 mouse.Methods Aged 6 weeks old,weight 25-30 g C57BL/_6 mice were collected.In the mouse tail injection compound of spore antigen and the Freud′s adjuvant.Then pours into through the trachea the antigen once a week.The mice were divided into 4 groups.Group A was the normal mouse,Group B was given Freud′s adjuvant(the same method)to determine whether there was affect to the mouse.Group C and D were injected spore antigen 2 and 4 times.When the antigen sensitization finished 1 week later group C and D were completely divided 2 groups,among them one group was inhalation 1.5% spore antigen and induce the acute response.Six hours later the bronchoalveolar lavage fluid(BALF) was collected to observe cell change,and excise the lung tissue to manufacture the pathology specimen,another group had not been induced the acute response and collect the BALF and to exsise the lung tissue directly.Group B were inhalted saline later to collect the BALF and the lung tissue.In the mouse blood serun,enzyme linked immunosorbent assay(ELISA) was used to mensurate antigen specific IgG.Results In group C and D,antigen specific IgG significantly inhanced than that in group A and B(all P
