Abstract

The study was aimed at identifying the globule leukocytes (GL) of tracheal mucosa layer of Korean native cattle showing symptom of pneumonia which have died as enterotoxemia and normal Korean native cattle in Kyungpook local area. In another set of experiment, Isolated Klebsiella pneumoniae from suddenly died cattle specimens was subjected to rat for a determining globule leukocyte appearance by using histochemical and immunohistochemical method. In histochemical study, globule leukocytes generally was existed in all the case of postmortem of Korean native cattle and 3 heads of slaughtered cattle which showing symptoms of pneumonia and it showed significant increase in tracheal mucosa of rats experimentally infected with Klebsiella pneumoniae. These increased number of globule leukocytes was moderately remained on early infection stage and gradually decreased in timedependent manner after infection. The granule patterns were also determined as an acidmucopolysaccharide. In immunohistochemical study, serotonin intensity in the treacheal mucosaepithelial cells of rat experimentally infected observed a strong immunoreactivity during early infection and gradually decreased in dependent of infection stage while no IgE immunoreactivity observed. These data show that globule leukocytes were increased in a pneumonia, therefore it was considered as a valuable cell that was associated with early stage of inflammatory response.
