Corn oil improved hepatic pathology in aging mice. Hematoxylin and eosin stained slides of liver (three sections from each mouse) from young control (YC), normal diet (N) and
high corn oil diet (HF) mice were scored and the number of mice at relevant categories based on the levels of vacuolar change (hydropic degeneration or lipidosis for the liver) was
reported. A set of representative images and bar graphs (means ± SE, n = 12–14/group) were shown. The arrows point to intracytoplasmic lipid vacuoles. 200× magnification. Scale
bar = 50 um. *P b 0.05.
