Abstract:
The hepatoprotective effects of fermented black rice bran extracts (FF1 and FF2: black rice bran fermented by Lentinus edodes derived from mycelium supplemented with soybean or Hovenia dulcis) and their associated mechanisms were evaluated. In an in vitro experiment, FFs caused significant amelioration of the metabolic function of rat hepatocytes treated with NH₄Cl. In addition, administration of FFs to rats with chronic liver injury induced by 12‐week continual alcohol consumption resulted in significant restoration of body weight shrinkage, notable attenuation of excessive aspartate aminotransferase, alkaline phosphatase and endotoxin in serum, malondialdehyde in liver and the lactulose/mannitol ratio in urine. Furthermore, FF1 or FF2 also caused significant downregulation of gene expression of several critical inflammatory mediators (interleukin‐6, tumor necrosis factor‐alpha, cyclooxygenase‐2 and inducible nitric oxide synthase). Histopathological findings also indicated that FFs reduced inflammation, necrosis and fatty infiltration in liver tissue. Taken together, FFs exert hepatoprotective effects through anti‐inflammatory and anti‐lipid peroxidative properties and regulation of intestinal permeability. PRACTICAL APPLICATIONS: In this study, mycelia fermentation was utilized as a feasible strategy for enhancing the hepatotherapeutic effect of black rice and herbs. The findings demonstrated that Hovenia dulcis exerts a synergistic protective effect on an alcoholic liver disease animal model and could provide a new effective potential approach to alleviate alcoholic liver diseases.
