Values are presented as median (ranges). ^¤Significance Behçet disease versus control subjects. BAL samples from 15 BD patients with pulmonary involvements and 18 healthy controls were investigated. Aliquots of fluid were removed for measurement of cell counts with a hemocytometer, cell viability was determined by means of trypan blue dye exclusion. Patients with BD exhibited increased values of total cell count in their BAL when compared to healthy controls. Significant differences were also observed Macrophages, lymphocytes and neutrophils were present in significant numbers in BAL from BD patients.
