ABSTRACT
Objective To investigate the expression of nerve growth factor(NGF)in the adrenaline medullary chromaffin cells(AMCC)and the morphological and functional changes in AMCC of asthmatic rats.Methods The 32 SD rats were randomly divided into two groups:control group(n=8)and asthma group(n=8).Asthma models were established by sensitization and challenge with ovalbumin(OVA).By means of immunohistochemistry(SP)combined with the micro-image analysis to investigate the alterations of NGF immunoreactivity in asthmatic rats and by means of light microscopy and electron microscopy to investigate the ultrastructural changes in AMCC,and detect the concentration of adrenaline and noradrenaline in serum by enzyme-linked- immunosorbent assay(ELISA).Results The positive immunoreactivity was increased in asthmatic AMCC compared with the controls(P
