In iImages a-d, an increase was of observed in alveolar septa (optical microscope image of lung sections stained with H&E with magnification 10X). The recorded scores are as follows: a = 1 (negative control), b = 2 (Exposure 30 mg/kg b.w of PQ), c = 3 (Exposure 60 mg/kg b.w of PQ), and d = 4 (Exposure 200 mg/kg b.w of PQ), e. lung tissue necrosis in the Exposure 200 mg/kg b.w of PQ (magnification 10X), f. the accumulation of cells in the alveoli in the Exposure 200 mg/kg b.w of PQ (magnification 40X), g. the formation of a hyaline membrane in the Exposure 200 mg/kg b.w of PQ (magnification 20X).
