Effects of Cornus mas Fruit Hydro-Methanolic Extract on Liver Antioxidants and Histopathologic Changes Induced by...

Cornelian cherry (Cornus mas) is a valuable source of phenolic antioxidants. The present study was aimed to investigate whether Cornus mas fruit hydro-methanolic extract (CMFE) can modulate the cisplatin-induced changes in liver antioxidant enzymes and histological structure. Forty Wistar rats were divided into a control group, cisplatin (Cis) group, CMFE group, CMFE 300 + Cis group, and the CMFE 700 + Cis group. After the intervention, blood and tissue samples were taken for biochemical and histopathological analysis. Cis caused reduction in the activity of liver antioxidant enzymes including SOD, GPx, TAC, and CAT and increased that of MDA. Moreover, exposure to Cis caused a reduction in serum level of AST, ALT, and ALP and a rise in serum level of GGT. Oral administration of CMFE for 16 days in the two different dosages at 300 and 700 mg/kg improved the Cis-induced changes of liver enzymes activity and serum enzymes level. Evaluating the histological structure of liver tissue, it was found that treatment by CMFE could ameliorate the Cis-induced changes to near normal histology. The results showed antioxidant and phenol contents in Cornus mas fruit could improve Cis-induced oxidative stress and liver histologic changes in rats.
