RESULTS: At 12 weeks after infusing thioacetamide, pathological section showed that hepatic lobules were destroyed; hepatic cord was disordered; liver cells had adipose degeneration, with few necrotic cells; interstitial fibrous tissues were hyperplastic, and folioles in some fibrous tissues, inflammatory cell infiltration were detected. These were the symptom of hepatic fibrosis.
