Abstract
ObjectiveEthylene glycol is widely used as a solvent and automobile antifreeze agent. Therefore, there have been a number of cases of human exposure from accidental or intentional ingestion of antifreeze, with the kidney being the most sensitive target organ. This study was designed to investigate the protective effect of seeds of Dolichos biflorus (Fabaceae), on ethylene glycol induced nephrotoxicity in adult female Wistar rats. MethodsThe hydro-methanolic (30:70, v/v) extract of D. biflorus was orally administrated at doses of 150 and 300 mg/kg body weight/day along with ethylene glycol (0.75% v/v) for 28 days. The results were compared with a parallel study conducted with standard marketed drug cystone under identical dosage conditions. The ionic chemistry was measured in urine and serum. Statistical differences and linear regression analysis were performed using GraphPad prism 5 software. ResultsEthylene glycol induced a significant elevation in the creatinine, uric acid, urea levels in urine as well as in serum and urinary electrolytes (sodium and potassium) excretion levels. D. biflorus significantly (P<0.001) protected the elevated levels of urine and serum parameters. Moreover, D. biflorus shows higher renoprotective index than cystone at identical dose levels. ConclusionsThese results provided an evidence of the significant protective effect of D. biflorus towards hyperuricemic and nephrotoxicity and thus can be used as potent dietary food.
