The effect of various high-fat diet on liver histology in the development of NAFLD models in mice.

Abstract

Nonalcoholic fatty liver disease (NAFLD) is exceptionally common around the world. The development of NAFLD is increasing rapidly in the world, along with changes in lifestyle. Excess lipid intake is one of the risk factors for NAFLD. The NAFLD model is induced by a high-fat diet contains SFA, MUFA, and ῳ-6 PUFA. This study aims to assess the effect of high-fat diet variation on liver histology in developing NAFLD models in mice. Thirty-six male mice (Balb/c) were divided into six groups fed a high-fat diet containing beef tallow 60%, beef tallow 45%, vegetable ghee, animal ghee+corn oil, vegetable ghee+corn oil for 28days and compared to a control group fed a chow diet. All of the mice were fed with a high-fat diet in the form of pellets ad libitum for 28days. Bodyweight and food intake were measured every day. At the last day of treatment, animals were sacrificed and the Liver were taken for histological analysis. This study showed that NAFLD model development was achieved in all group mice fed a high-fat diet with different degrees of NAFLD. Beef tallow 60% had the worst liver histology. Thus, based on this study, we found that high-fat diet variations influenced the development of NAFLD models in mice, particularly concerning liver histology.
