Masson staining of hepatic tissues in each group of rats.

<p>Slightly sinusoidal fibrosis appeared only in part of model rats until 16^th week (B). At the end of 24^th week, all model rats showed hepatic fibrosis in sinusoids, partly in portal area (C). These changes were improved in the liver of simvastatin-treated rats (D). A: Control ×200; B: 16^th week ×200; C: 24^th week ×200; D: Simvastatin-treated group ×200.
