Differential cell counts in bronchoalveolar lavage (BAL) of patients with tuberculosis (TB), acute respiratory distress syndrome (ARDS) and the combination of both TB and ARDS. Cytospins of BAL cells were distinguished by diff Quick staining and by morphology (Hemacolor, original magnifi cation x 1,000) (A). Total cells were counted and the percentage of each cell type was calculated when the counted total cell numbers were more than 200 and represented as neutrophils, macrophages and lymphocytes (B). The data among groups were analyzed using one-way analysis of variance, and the differences between two groups were tested using an unpaired t test; P ≤ .05 was considered significant. Data are presented as mean ± SEM (n = 30 in each group). *p ≤ 0.05 between groups.
