Impact of Exposure to Fenitrothion on Vital Organs in Rats

Figure 10

Effects of fenitrothion on lung histopathology in rats using H & E staining (400). C: normal lung tissue, F1: slight hypertrophied vascular smooth muscles, F2: mild hypertrophied vascular smooth muscles, F3: moderate hypertrophied vascular smooth muscles and thickened intra-alveolar septa, F4: severe hypertrophied vascular smooth muscles and thickened intra-alveolar septa, and F6: severe hypertrophied vascular smooth muscles, interstitial hemorrhages with narrow alveolar spaces, and intense thickened septa with perivascular leukocytic aggregation. N: normal lung cells. Black star: hypertrophied vascular smooth muscles. Green lightning: thickening in the alveolar septa. Red arrow: perivascular leukocytic aggregation.
