Arachidonate metabolites in bronchoalveolar lavage fluid from horses with and without COPD

Abstract
Summary: Arachidonate metabolites were measured in bronchoalveolar lavage fluid (BALF) from horses with (N = 4) and without (N = 7) chronic obstructive pulmonary disease (COPD). Prostaglandin (PG) D2, leukotriene (LT) B4and LTC4were present in highest concentrations in BALF from clinically normal horses. Concentrations of PGE2and PGF were significantly higher in BALF from horses with COPD than in BALF from normal horses, but no differences were detected in thromboxane B2, 6‐keto‐PGF, PGD2, LTB4or LTC4.
