F. Savari et al. studied the effect of fructose, fat-rich and Western diet feeding along with aggravative effect of cigarette smoking on liver status in 64 male mice. The mice were assigned into 4 groups that fed standard, fructose-rich, high fat-, and western-diet for 8 weeks. Then each group was divided in two smoker and nonsmoker subgroups according to smoke exposing in the last 4 weeks.
Serum liver enzymes and lipid profile levels in Western diet fed mice were significantly higher than in other diets. Exposing to cigarette smoke led to a significant increase in hepatic damage shown as more severe fat accumulation, hepatocyte ballooning and inflammation infiltrate. Elevated TNF-α level confirmed incidence of liver injury.
