Abstract:
:The present study investigates the prophylactic effect of Nymphaea alba against ferric nitrilotriacetate (Fe-NTA)-induced renal oxidative stress, hyperproliferative response and renal carcinogenesis in Wistar rats. Treatment with Fe-NTA (9 mg Fe/kg body weight, intraperitoneally) enhanced iron-ascorbate-induced renal lipid peroxidation, xanthine oxidase, gamma-glutamyl transpeptidase and hydrogen peroxide (H2O2) generation with reduction in renal glutathione content, antioxidant enzymes, viz., glutathione peroxidase, glutathione reductase, catalase, glucose-6-phosphate dehydrogenase and phase-II metabolising enzymes such as glutathione-S-transferase and quinone reductase. It also elevated the levels of blood urea nitrogen, serum creatinine, ornithine decarboxylase (ODC) activity and thymidine [3H] incorporation into renal DNA. It also enhanced DEN-initiated renal carcinogenesis by increasing the percentage incidence of renal tumors. Treatment of rats orally with N. alba (100 and 200 mg/kg body weight) resulted in significant decrease in gamma-glutamyl transpeptidase, lipid peroxidation, xanthine oxidase, H2O2 generation, blood urea nitrogen, serum creatinine, renal ODC activity, DNA synthesis (p < 0.001) and incidence of tumors. Renal glutathione content (p < 0.01), glutathione metabolizing enzymes (p < 0.001) and antioxidant enzymes were also recovered to significant level (p < 0.001). Thus, our results show that N. alba is a potent chemopreventive agent and suppresses Fe-NTA-induced oxidative stress, hyperproliferative response and renal carcinogenesis in Wistar rats.
