Specific Enzyme Activities in Bronchoalveolar Lavage Fluid as an Aid to Diagnosis of Tracheobronchitis and Bronchopneumonia in Dogs. Research in Veterinary Science, 71(2), 141-145.

Bronchoalveolar lavage (BAL) fluid was obtained from 26 dogs (20 with respiratory diseases and six controls) following anaesthesia with sodium pentothal. Enzyme activities and biochemical parameters were measured in BAL fluid. LDH and ALP levels were significantly increased in 12 dogs with bronchopneumonia, but not in eight dogs with tracheobronchitis. Insignificant and variable levels of TP and UN concentrations were found in both groups. It was concluded that LDH and ALP enzyme activities could be considered as pointers to pulmonary inflammation and/or damage while TP and UN measurements in BAL fluid may have a place in the identification of changes in respiratory and vascular permeability.
