  1. Histological evaluation of H&E-stained lung tissue from C57 mice, contrasting control and smoke-exposed groups, complemented by a statistical analysis of lung injury scores (n=6 per group).
  2. Lung injury-related indicators: a. lung wet-to-dry ratio, b. superoxide dismutase (SOD), c. glutathione (GSH), and d. malondialdehyde (MDA). Three separate studies were conducted, and the results are expressed as the mean ± standard deviation (SD), n = 8.
  3. Variations in the concentration of the main gas components during combustion. Three independent experiments were performed.
