title: Bronchoscopy and cytological examination of bronchial secretions of horses with chronic obstructive pulmonary disease (COPD).
abstract: On the basis of cytological similarities in chronic obstructive disease (COPD) in human beings and in horses during 1981 a total number of 144 horses with COPD were examined. Bronchial secretions were taken under endoscopic control and stained with a modified Hansel staining procedure. Whereas 26 horses did not exhibit signs of allergic reactions cytologically and 94 horses showed low amounts of eosinocytes and/or mast cells in their secretion; only the secretions of 24 horses (16,67%) were characterized by fairly high contents of these allergy associated cells and low numbers of neutrophilic granulocytes.
