ABSTRACT
We studied an ethyl acetate (EtoAC) extract of leaves obtained
from the medicinal and ornamental tree, Lagerstroemia speciosa L,
for nephroprotective activity in cisplatin-induced acute renal injury in
Balb/C mice. The EtoAC extract at dose levels of 50 and 250 mg/kg
showed a dose-dependent reduction in cisplatin-induced elevations in
urea and creatinine concentrations. Additionally, treatment with the
EtoAC extract prevented the cisplatin-induced decline of the renal
antioxidant enzymes superoxide dismutase, catalase, glutathione
peroxidase, and reduced glutathione. The findings suggest that the
EtoAC extract from L. speciosa possesses marked nephroprotective
activity and could offer a promising role in the treatment of acute
renal injury caused by a nephrotoxin like cisplatin.

INTRODUCTION
Cisplatin is a potent antineoplastic drug, whose optimal clinical
use is limited because of its ability to induce nephrotoxicity l\l. Acute
