What Are the Common Findings in Histological Studies of Air Pollution?
Histological studies of air pollution often reveal several characteristic findings:
1. Inflammation: Increased infiltration of inflammatory cells such as macrophages and neutrophils in the alveolar and bronchial regions. 2. Fibrosis: Deposition of extracellular matrix proteins leading to thickened alveolar walls, indicative of lung fibrosis. 3. Cellular Damage: Evidence of necrosis, apoptosis, and structural changes in epithelial cells. 4. Oxidative Stress: Increased expression of oxidative stress markers and enzymes like superoxide dismutase (SOD).
