Figure 7
Masson stain of liver sections (×100). Hepatic photomicrographs of representative rats are shown from each of the five groups. (a) Control liver tissue. (b) Liver tissue of rats treated with O-Tyr (2 mg/mg). (c) Liver tissue of rats treated with O-Tyr (4 mg/mg). (d) Liver tissue of rats treated with O-Tyr (8 mg/mg). (e) Liver tissue of rats treated with Tyr (8 mg/mg). Notes. PA: portal area. The blue color suggests tissue fibrosis in portal area.
