The effect of radish sourced 4-(Methylthio)-3-butenyl isothiocyanate on ameliorating the severity of high fat diet inducted nonalcoholic fatty liver disease in rats.

The aim of this study is to develop a high fat diet and over nutrition induced nonalcoholic fatty liver disease(NAFLD) in rat, and to investigate the effect of 4-(Methylthio)-3-butenyl isothiocyanate (MTBITC) on ameliorating the NAFLD. Twenty Sprague-Dawley (SD) rats were equally divided into 4 groups (C, M, E1 & E2). Control group (C) were treated with standard restricted diet; Model group (M) were given high fat liquid diet ad libitum; Experimental group (E1 & E2) were treated with high fat liquid diet ad libitum and MTBITC by gavage. The experiment last 9 weeks, and serum chemistry and liver histology were assessed. The rats of M group showed severe lipid deposition and peroxidation in liver. When compared with group C, group M also showed significantly higher serum concentration of low-density lipoprotein, tumor necrosis factor-α and glucose. Histopathologic sections demonstrated lipid accumulation and macrovascular steatosis with ballooning degeneration in the livers of M. Group E2 presented significantly better conditions when assessed based on the parameters of NAFLD. The data suggested that MTBITC might significantly attenuate fat liquid diet induced NAFLD.
