Table 1.
The correlation of Muc5ac(+) cells or the IL-13 concentration with the number of inflammatory cells. The correlation between percentage of Muc5ac (+) epithelial cells or concentration of IL-13 in BAL fluid and number of eosinophil, neutrophil and mast cell in sham (n = 6) and TiO2 – instilled rats (n = 7).
| Correlation (ρ) | Eosinophils No. in BAL fluid | Neutrophils No. in BAL fluid | Mast cells No. in trachea |
| % of Muc5ac (+) | 0.156 (p = 0.549) | -0.195 (p = 0.438) | 0.813 (p = 0.001*) |
| Concentration of IL-13 in BAL fluid | 0.447 (p = 0.138) | 0.193 (p = 0.57) | 0.903 (p = 0.0001**) |
* p < 0.05, ** p < 0.01
