Effect of Sairei-to on gentamicin nephrotoxicity in rats.
The effect of Sairei-to, an oriental traditional medicine, against gentamicin nephrotoxicity was examined in gentamicin nephrotoxicity rat models. Gentamicin nephrotoxicity was induced by s.c. injection of gentamicin (100 mg/kg/day, for 3 days) in male Sprague-Dawley rats. Renal functions of two rat groups were compared, one eating rat chow containing 2.5% Sairei-to, the other eating normal rat chow. Sairei-to administration reduced the increase of urinary N-acetyl-beta-D-glucosaminidase (NAG) and protein excretion, and decreased creatinine clearance induced by gentamicin. Gentamicin increased renal cortical malondialdehyde (MDA) concentration in normal diet group but not in the Sairei-to diet group. The renal cortical gentamicin concentration was not different between the two groups. In conclusion, Sairei-to shows reno-protective action against gentamicin nephrotoxicity, possibly through its anti-oxidant action.[1]References
