Histopathology of the liver from rats treated with carbon tetrachloride (CCl4) twice a week for 6 weeks, then left untreated for a 6-week period of recovery. (a) Liver from a rat treated with CCl4 for 6 weeks at 0.4 ml/kg and left untreated for a 6-week recovery period. There is perivascular fibrosis with some evidence of delicate partial bridging within the liver parenchyma. (b) Liver from a rat treated with CCl4 for 6 weeks at 1.0 ml/kg and left untreated for a 6-week recovery period. There is perivascular fibrosis in centrilobular and portal regions, with delicate bridging of fibrosis between these areas. Original magnification of both images; ×100 (Sirius red).
