Effects of selenium-enriched Agaricus blazei Murill on liver metabolic dysfunction in mice, a comparison with selenium-deficient Agaricus blazei Murill and sodium selenite.

In the present study, we investigated the effects of Se-enriched Agaricus blazei Murill (Se-AbM) on liver injury in mice induced by acute alcohol administration. Mice received ethanol (5 g/kg body weight (BW)) by gavage every 12 h for a total of 3 doses. Se-AbM was administrated before ethanol administration. Subsequent serum alanine aminotransferase (ALT) level, aspartate aminotransaminase (AST) level, maleic dialdehyde (MDA) level, hepatic total antioxidant status (TAOS), nuclear factor kappa B (NF-κB) level, polymorphonuclear cells (PMN) level, interleukin-1β (IL-1β) level, inducible nitric oxide synthase (iNOS) level, tumor necrosis factor-α (TNF-α) level, intercellular adhesion molecule 1 (ICAM-1), and cyclooxygenase-2 (COX-2) were determined by ELISA and immunohistochemistry, respectively. Se-AbM administration markedly (p < 005) decreased serum ALT, AST, and MDA levels, hepatic IL-1β and TNF-α levels, as well as PMN infiltration and the expression of ICAM-1, COX-2, iNOS, and NF-κB compared with alcohol administration. In conclusion, we observed that Se-AbM supplementation could restrain the hepatic damage caused by acute alcohol exposure.
