The protective effects of Curcuma aromatica leaf extract were studied on nehrotoxicity induced by arsenic trioxide in albino rats. LD50 estimated for arsenic trioxide was 14.98 mg kg(-1) body weight. Nephrotoxicity was assessed by estimating the serum levels of urea, uric acid and creatinine, the markers of renal dysfunctioning. The applied doses of arsenic trioxide administered orally were 0.0...
