PROTECTIVE ROLE OF DAIDZEIN AGAINST CYCLOPHOSPHAMIDE INDUCED NEPHROTOXICITY IN EXPERIMENTAL RATS
Objective: To evaluate the protective effect of daidzein on cyclophosphamide (CPA) induced nephrotoxicity in experimental rats.
Methods: The Wistar rats of either sex were randomly divided into five equal groups: Group I (normal saline 1 ml p. o.), Group II (CPA 150 mg/mg i. p), Group III (Daidzein 20 mg/kg p. o.+CPA 150 mg/kg, i. p.), Group IV (Daidzein 40 mg/kg p. o.+CPA 150 mg/kg, i. p.) and Group V (Daidzein 40 mg/kg p. o., alone). Rats of all groups except Group I and Group V treated with CPA in a dosage of 150 mg/mg i. p in the last five days of treatment. Blood samples were collected on 11th day from each rat and subjected for the evaluation of serum markers such as Serum creatinin, serum urea and serum uric acid. Kidney of each rat was excised and subjected for antioxidant parameters evaluation such as malonyl dialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), catalase and histopathological study.
Results: Daidzein explored a significant (P<0.001) role in CPA-induced nephrotoxicity by suppressing serum creatinine, serum urea and serum uric acid. Daidzein also demonstrated significant (P<0.001) protection against CPA-induced nephrotoxicity by decreasing MDA level and by elevating the GSH, SOD, catalase at different doses.
Conclusions: The obtained results of present study revealed that daidzein attenuates the CPA-induced nephrotoxicity by antioxidant defence action in rats.
