Different Dietary Proportions of Fish Oil Regulate Inflammatory Factors but Do Not Change Intestinal Tight Junction ZO-1 Expression in Ethanol-Fed Rats

Figure 1

Effects of fish oil on H&E staining of liver tissue sections in rats with chronic ethanol feeding. CV: central vein; PV: portal vein; C: control group; CF25: control diet with fish oil substituted for 25% of olive oil; CF57: control diet with fish oil substituted for 57% of olive oil; E: ethanol group; EF25: alcohol-containing diet with fish oil substituted for 25% of olive oil; EF57: alcohol-containing diet with fish oil substituted for 57% of olive oil. H&E staining showed hepatocyte degeneration and necrosis accompanied by inflammatory cell infiltration (triangle) in group E. Moreover, fatty changes (arrow) were also found in group E.
