Hepatoprotective Effects of Alpinia Officinarum Rhizome Extract on Cisplatin-Induced Hepatotoxicity in Rats: A Biochemical, Histopathological and Immunohistochemical Study.

Background: Alpinia officinarum is a member of the ginger family (Zingiberaceae), which is widely cultivated in Asia and traditionally used for its anti-inflammatory, antimicrobial, and antihyperlipidemic qualities. This study aimed to evaluate the effect of Alpinia officinarum rhizome extract (AORE) on cisplatin (CP)-induced hepato-toxicity in rats.Methods: Forty-four male rats were divided into six groups including the control group, AORE control group, CP control group, and three groups of CP (7 mg/kg dose, on the 10th day) with AORE (at concentrations of 100, 200 and 400 mg/kg, daily for 14 days). After 14 days, the rats' livers were removed and their liver function was assessed using biochemical marker enzymes including serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) activities and albumin, total protein, and total bilirubin (T. bilirubin). Oxidative stress was assessed by evaluating malondialdehyde con-centration and hepatic superoxide dismutase activity, histopathological and immunohistochemical tests were also conducted.Results: Results demonstrated that treatment with AORE reduced the toxicity in levels of the hepatic biomarkers in cp-induced groups. AORE treatment decreased oxidative stress and improved histopathological indexes. Furthermore, immunohistochemical (IHC) investigation showed the B-cell lymphoma 2 (Bcl-2) upsurging and p53 downregulating expression exhibiting the recovery following AORE administration.Conclusion: The founding suggested that AORE administration has positive biochemical, histopathological, and immunohistochemical impacts on the ameliorating of hepatotoxicity in CP-induced rats.
