Hydrolyzed whey peptide-based diet ameliorates hepatic ischemia-reperfusion injury in the rat nonalc

Study Abstract

PURPOSES:
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.
METHODS:
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.
RESULTS:
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-α 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.
CONCLUSION:
The administration of a HWP diet ameliorated the hepatic I/R injury in rats with NAFLD.
