The representative histological sections of rat liver specimens. A: hematoxylin and eosin stain at 20 × 10 magnification, B: semi-quantitative scores graded from 0 (no lesion), 1 (trace lesion), 2 (weak lesion), 3 (moderate lesion) to 4 (severe lesion) for fat changes, and from 0 (no lesion), 1 (lesion in the central vein area), 2 (lesion in the central vein area and expansion to the surrounding area) to 3 (lesion in the central and portal vein areas or cirrhosis) for necrosis, inflammation and fibrosis in control, CCl₄, GE and Rb1 groups. Solid and dashed arrows represent the central vein and collagen fibers. Data are presented as mean ± SD (n =10). Values not sharing the same letter differ significantly (p <0.05). Scale bar =50 μm.
