Hepatic histopathology and apoptosis in diet-induced-obese mice under Escherichia coli pneumonia

Figure 4. The changes of lipid droplet deposition in the liver after E. coli infection. (A–D) The representative images of the liver lipid droplets deposition at 72h after receiving intranasal instillations (Oil Red O staining, bar=100 μm). (A) lean group; (B) lean-E. coli group; (C) DIO group; (D) DIO-E. coli group; (E) the integrated optical density of hepatic lipid droplets. Note: Letter a, b, c or d represent difference (p<0.05) between the group and the lean group, lean-E. coli group, DIO group, or DIO-E. coli group, respectively.
