摘要
The number of patients with nonalcoholic fatty liver disease (NAFLD) is increasing. Hepatic steatosis is a major risk factor for hepatic failure after ischemia-reperfusion (I/R) injury. Hydrolyzed whey peptide (HWP) is a functional liquid-type nutritional diet containing whey peptide, which has previously been shown to exert anti-inflammatory effects. In the present study, we examined the effects of HWP on the hepatic I/R injury in a rat NAFLD model. %26lt;br%26gt;Rats fed a methionine/choline-deficient diet for 4 weeks were divided into two groups after 30 min of whole liver ischemia. In Group-M, HWP was given immediately after reperfusion and every 6 h thereafter. In Group-C, the vehicle was given in the same manner. The liver function tests and microscopic findings of the liver after reperfusion were compared between the two groups. %26lt;br%26gt;The serum transaminase levels in Group-M were significantly lower than those in Group-C after reperfusion. The gene expression levels of IL-6 and inducible nitric oxide synthase (iNOS) were significantly lower in Group-M compared to Group-C. The TNF-alpha and uncoupling protein-2 (UCP-2) expression levels were also markedly lower in Group-M. The hepatic necrotic areas in Group-M were significantly smaller than those in Group-C. %26lt;br%26gt;The administration of a HWP diet ameliorated the hepatic I/R injury in rats with NAFLD.
