Table 2. Total and differential bronchoalveolar lavage (BAL) cell counts.

	Bleo/PBS (n = 8)	Bleo/IL-2-Bax (n = 8)	Bleo/IL-2-PE (n = 6)	Sal/PBS (n = 9)
Total (×106 cells/ml)	0.21 ± 0.03*	0.13 ± 0.02†	0.11 ± 0.03†	0.04 ± 0.004
Lymphocytes (%)	29 ± 7‡	13 ± 1†	14 ± 4†	0.5 ± 0.2
Macrophages (%)	63 ± 8‡	77 ± 2†	79 ± 6†	99 ± 0.3
Neutrophils (%)	7 ± 1.5‡	9 ± 1.5	9 ± 2.5	0.1 ± 0.1

Total and differential cell counts from the bronchoalveolar lavage (BAL) fluid are presented as mean ± SEM for each group. Differential counts are given as a percentage of the total cell count.

^*P < 0.001 compared to Sal/PBS.
