Nephroprotective Potential of Urtica parviflora Roxb. Against Paracetamol Induced Nephrotoxicity in Rats
Sangeeta P. Sah,
Objective: To investigate nephroprotective potential of Urtica parviflora (UP) against paracetamol (PCM)
induced nephrotoxicity in rats.
Methods: Nephrotoxicity was induced in rats by chronic administration of PCM (1 g/kg body weight p.o.) for 21 days.
Different doses of UP (250, 500 and 750 mg/kg b.w., p.o.) were administered for 21 days along with PCM. Blood urea,
blood urea nitrogen (BUN), serum creatinine, total protein, serum and tissue nitrite, renal enzymatic and non-enzymatic
antioxidants along with lipid peroxidation were evaluated. The effect of extract treatment on the renal histopathological
profile in PCM nephrotoxic rats was also evaluated.
Results: PCM treatment significantly elevated blood urea, BUN, creatinine, serum nitrite and renal lipid peroxidation
along with significant decrement in renal enzymatic and non-enzymatic antioxidants, total proteins while UP treatment
significantly attenuated these alterations. The extract was also effective in mitigating renal histopathological changes
induced by PCM.
Conclusions: The results suggested potent nephroprotective and antioxidant properties of Urtica parviflora.
Keywords: Urtica parviflora, paracetamol, nephrotoxicity, antioxidant activity, enzymatic, non-enzymatic, lipid, serum, protien, antioxidant.
