|---|---|---|---|
| No. of animals examined | 5 | 5 | |
| Adhesions | |||
| Lung and chest wall (+) | 1 (1) | 2 (2) | |

Criteria for histopathological classification: Adhesions: +, present; Fibrosis in the pleura: +, localised; ++, diffuse; Mesothelial cell hypertrophy in the pleura: +, mild; Alveolar epithelial cell cuboidal epithelialization: +, localised; ++, diffuse; Alveolar mononuclear cell infiltration: +, localised; Interstitial mononuclear cell infiltration: +, localised; ++, diffuse.
