Histopathological examination of liver sections from rats treated with TAE from YHS. Liver sections of male Sprague–Dawley rats treated with various dosages of TAE showed largely normal appearances. For each dosage group, four sections were made, and the microphotos show representative foci in the control rats (A), 6 mg/kg (B), 30 mg/kg (C), and 150 mg/kg (D) TAE-treated rats. Tissues were fixed in formalin and stained with hematoxylin and eosin. Magnification: 200 × .
