Metalloproteinases and Their Tissue Inhibitors in Comparison between Different Chronic Pneumopathies in the Horse

Table 5

For BAL cytology, the results of cell percentages are expressed as mean ± SD. shows significant differences to controls at , significant increase in RAO compared to IAD and CIP, and significant decrease in RAO compared to IAD and CIP. RAO: recurrent airway obstruction, IAD: inflammatory airway disease, and CIP: chronic interstitial pneumopathy.
