Abstract

Hyperoxaluria is an imperative risk factor for calcium oxalate stone formation in nephrolithiasis. The in vitro and in vivo investigations indicated that oxidative stress plays a significant role in the development of kidney stone. NADPH oxidase is considered as a major source of ROS in hyperoxaluric conditions. Apocynin, a NADPH oxidase inhibitor, is a natural nontoxic compound isolated from a medicinal plant, Picrorhiza kurroa. It prevents activation of NADPH oxidase by blocking the assembly of cytosolic units with the membrane complex. Hence the present study was designed to investigate the effect of apocynin on ethylene glycol induced hyperoxaluria in male Wistar rats. Four groups were designed with 6 animals each. Control rats were given normal saline intraperitonealy. EG group rats received 0.4% ethylene glycol and 1% ammonium chloride in drinking water for 9 days to induce hyperoxaluria. Apocynin group rats received apocynin alone (200 mg/kg body weight, i.p. per day) for 9 days. EG+Apocynin group rats received 0.4% ethylene glycol and 1% ammonium chloride in drinking water along with apocynin (200 mg/kg body weight, i.p. per day) for 9 days. Urine was collected on 9th day and rats were sacrificed on day 10. Their kidneys were processed for localization of crystals and various other biochemical analyses. Results indicated significant reduction in the oxidative stress and improvement in the renal dysfunction in apocynin treated hyperoxaluric rats. In conclusion, apocynin presented itself as a safe and effective remedy in combating hyperoxaluria induced nephrolithiasis.
