Ginsenoside-Rd has been proved to decrease the severity of renal injury ind
uced by cisplatin, in which proximal urinaferous tubules represent the main
site of injury. When ginsenoside-Iid was given orally at a dose of 1 or 5
mg/kg body weight/day for 30 consecutive days prior to cisplatin injection,
the activities of the antioxidation enzymes superoxide dismutase and catal
ase were higher, while malondialdehyde levels in serum and renal tissue wer
e lower in the treated rats than in the controls. The levels of urea nitrog
en and creatinine in serum were decreased in rats given ginsenoside-Rd. Dec
reased urinary levels of glucose, sodium and potassium reflected a protecti
ve action against the renal dysfunction caused by cisplatin. In addition, i
t was demonstrated that ginsenoside-Iid affected cultured proximal tubule c
ells exposed to cisplatin.
