Objective: Alpha-lactalbumin (αLA) accounts for about 20% of whey protein, which shown to have anti-inflammatory effects, but its effects on acute hepatitis have not been reported. We investigated the hepatoprotective effects of αLA in an acute hepatitis model. Since the effects of αLA on macrophages, which are related to inflammation, have not been clarified, we conducted DNA microarrays to investigate the anti-inflammatory mechanism of αLA. Methods: Sprague-Dawley rats were divided into three groups; control diet-fed group (Normal), D-galactosamine (GalN) and lipopolysaccharide (LPS)-treated and control diet-fed group (GalN/LPS), and GalN/LPS-treated, αLA- containing diet-fed group (GalN/LPS+αLA). One week after starting the test diet, rats were injected with GalN/LPS and the parameters in blood and liver were eva.. View More»
