Total and differential cell counts in bronchoalveolar lavage fluid (cells/ml).
| Control | Exercise | LPS | Exercise+LPS | P | |
|---|---|---|---|---|---|
| total cells | 1.35 ± 1.71 | 1.30 ± 2.01 | 8.73 ± 3.08a | 7.30 ± 0.68 | <0.001 |
| neutrophils | 0.04 ± 0.04 | 0.04 ± 0.05 | 7.28 ± 1.56a | 6.00 ± 3.02 | <0.001 |
| lymphocytes | 0.04 ± 0.07 | 0.02 ± 0.02 | 0.15 ± 0.14 | 0.16 ± 0.20 | ns |
| macrophages | 1.11 ± 0.50 | 1.00 ± 0.60 | 1.12 ± 0.60 | 0.86 ± 0.60 | ns |
| eosinophils | 0.02 ± 0.04 | 0 | 0.01 ± 0.03 | 0.04 ± 0.05 | ns |
a indicates the significant effect of LPS in increasing cell counts; values are expressed as the means ± SD. LPS, lipopolysaccharide; ns, non-significant.
