Abstract:
Objective Recently, The incidence of fatty liver is increasing , with the improvement of people′s living standard. We here established an available model with non-alcoholic fatty liver disease in rabbits and then studied its sonographic findings . Methods Forty male Japanese rabbits were randomly divided into 2 groups:control group and model group.The rabbits in model group were fed with high-fat diet for the establishment of the model of non-alcoholic fatty liver disease.The rabbits in control group were fed with standard diet. At the baseline, 12th, 16thand 20th week , all the livers in 2 groups were scanned by ultrasonography, and at the end of 20 th week, all the rabbits in 2 groups were killed for pathological analysis. Results Both the ultrasonography and in pathology demonstrated the successful establishment of non-alcoholic fatty liver models.The result of study demonstrated significant differences (P<0.05).At the 12th week, all of the 19 livers in model group showed fatty livers in sonography:8 low-, 9 middle-and 2 high-grade.The degree of steatosis aggravated pro-gressively with modeling time.Most of livers showed middle-grade fatty at the 16th week, and at the 20th week, they all demonstrated middle-or high-grade fatty liver:10 middle-and 9 high-grade, furthermore, ascites occurred in 3 cases.The pathological results were consistent with the findings of sonography, and fibrosis were observed in pathology. Conclusion Animal model with non-alcoholic fatty liver disease in rabbits can be established by high-fat diet.Besides, ultrasonography is a good method to monitor the establishment of the model .
