Fig. 3From: Chronic exposure to ambient particulate matter induces gut microbial dysbiosis in a rat COPD modelExposure to biomass fuel (BMF) and motor vehicle exhaust (MVE) induces effects consistent with chronic obstructive pulmonary disease in rats. a Lung sections show significant increases in the mean linear intercept after 24 weeks of BMF and MVE exposure. b The thickness of the small airway wall increased significantly in the rats after 24 weeks of BMF and MVE exposure. c Effects of BMF and MVE exposure on rat pulmonary function test results. n = 6. **p < 0.01.
