Results are ranked by time course. Necroinflammatory change was scored as A (0), no change; A (1–3), mild; A (4–6), moderate necroinflammation. Fibrosis was graded as F (0-1) for observations ranging from normal tissue to fibrous expansion of portal tracts and F (2-3) for bridge fibrosis to frequent bridging fibrosis with nodule formation. The fatty change was classified by its presence or absence (+/−). The number of rats was counted and used to calculate the percentage of each histopathological level at each time point.
n: number of rats.
