Figure 4: Effects of GA on the liver histological structure of rats with DMN-induced liver fibrosis (hematoxylin–eosin staining, 200×), n = 8 animals/group, scale bar: 50 μm. The treatments were as follows: (a) control group, (b) DMN (3 mg/kg; 7 mg/kg), (c) DMN + silymarin (100 mg/kg), (d) DMN + GA (25 mg/kg), (e) DMN + GA (50 mg/kg), and (f) DMN + GA (100 mg/kg). Hyperplastic wire mesh-like collagen fibers around the liver cells (black circle), inflammatory cell infiltration (white arrow), and congestion in ECM (black arrow) were found in the DMN group.
