Total antioxidant and oxidant status of plasma and renal tissue of cisplatin-induced nephrotoxic rats: protection by floral extracts of Calendula officinalis Linn.

Total antioxidant and oxidant status of plasma and renal tissue of cisplatin-induced nephrotoxic rats: protection by floral extracts of Calendula officinalis Linn. Ren Fail. 2016 Feb;38(1):142-50 Authors: Verma PK, Raina R, Sultana M, Singh M, Kumar P Abstract Absract The present study was aimed to determine the total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) of plasma and renal tissue in cisplatin (cDDP) induced nephrotoxic rats and its protection by treatments with floral extracts of Calendula officinalis Linn. Treatment with cDDP elevated (p < 0.05) the levels of blood urea nitrogen, creatinine (CR), TOS, OSI and malondialdehyde (MDA) but lowered (p < 0.05) total plasma proteins, TAS, total thiols (TTH), blood glutathione (GSH) and antioxidant enzymes compared to the control group. Pre- and post-treatments of ethanolic floral extract of C. officinalis along with cDDP restored (p > 0.05) CR, albumin, TOS, GSH and activities of antioxidant enzymes in blood and renal tissue. Ethanolic extract treatments reduced (p < 0.05) MDA level in renal tissue without restoring the erythrocyte MDA level following cDDP treatment. These observations were further supported by the histopathological findings in renal tissue. Observations of the present study have shown that treatments with ethanolic floral extract of C. officinalis protect cDDP induced nephrotoxicity by restoring ...
