| Group | Total cell count (x106/l) | Neutrophil (%) | Lymphocyte (%) | Macrophage (%) |
|---|---|---|---|---|
| Control | 4.20±2.41 | 3.02±1.96 | 3.96±2.02 | 86.52±12.49 |
| CS | 14.6±4.37b | 21.64±10.73b | 8.38±4.82b | 63.73±12.55b |
| ERY | 10.3±3.67b,c | 12.74±5.16b,d | 10.54±5.52a,c | 73.65±15.69a,c |
a
P<0.05
b
P<0.01 vs. control group
c
P<0.05
d
P<0.01 vs. the CS group. Data are presented as the mean ± standard deviation (n=12). Control rats were exposed to normal air and received daily saline injections. CS rats were exposed to CS for 12 weeks. CS + ERY rats were exposed to CS for 12 weeks and received daily injections of 100 mg/kg ERY. CS, cigarette smoke; ERY, erythromycin.
