Effect of daidzein on cisplatin-induced hematotoxicity and hepatotoxicity in experimental rats

The objective of the study was to investigate the effect of daidzein flavonoid on cisplatin (CP)-induced hematotoxicity and hepatotoxicity in experimental rats.

The Wistar rats were randomly divided into four equal groups: Normal (saline 1 ml p.o.), CP (7.5 mg/kg once intraperioteneally on 16^th day), test group of low dose (combination of CP and daidzein 20 mg/kg p.o. for 21 days), and test group of high dose (combination of CP and daidzein 40 mg/kg p.o. for 21 days). Blood samples were collected on 22^nd day from each rat and subjected for evaluation of hematological parameters such as red blood corpuscles (RBC), white blood corpuscles, hemoglobin (Hb) and platelets, and serum biomarkers such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP). Liver of each rat was excised and subjected for antioxidants evaluation such as malonyl dialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), catalase, and histopathological study.

Daidzein had a significant (P < 0.001) beneficial role in CP-induced hemotoxicity by increasing RBC, Hb, packed cell volume, and platelets. Daidzein also exhibited a significant (P < 0.001) protection against CP-induced hepatotoxicity by decreasing ALT, AST, ALP, and MDA level and by elevating the GSH, SOD, and catalase.

Daidzein attenuates CP-induced oxidative stress on blood cells and antioxidants in rats.
