Objectives: The aim of the present research was to histopathologically investigate the potentially advantageous effects of the flavonoid fisetin on liver damage induced by the chemotherapeutic drug doxorubicin (DOX) in rats. Methods: Thirty-five Wistar albino female rats were randomized in five as Control, dimethyl sulfoxide (DMSO, solvent), fisetin (50 mg/kg/day; 7 days i.p.), DOX (single dose, 10 mg/kg; i.p.) and DOX+fisetin (10 mg/kg DOX+50 mg/kg/day fisetin for 7 days). Livers were harvested, fixed in 10% formalin, and processed for histopathology by hematoxylin-eosin staining. Central to these analyses of damage parameters for inflam-mation, sinusoidal dilatation, and hepatocyte injury were examined histopathologically. Results: The DOX group had severe hepatocyte degeneration, inflammation, and sinusoidal dilatation. In con-trast, the DOX+fisetin group expressed mild sinusoidal dilatation and insignificant inflammatory change. In this context, statistical significance was found between the DOX group and the DOX+fisetin group in terms of hepatocyte degeneration and inflammation (P<0.01), and sinusoidal dilatation (P=0.038). However, no sig-nificant differences were observed in between the Control, fisetin, and DMSO groups (P=1.000). Conclusions: Fisetin conferred substantial histological protection from DOX-induced liver injury in rats. The amelioration may have resulted from the fisetin's antioxidant, anti-inflammatory, and perhaps membrane-stabilizing effects, thus proving its potential as a hepatoprotective agent.
