摘要

This study aimed to assess the protective effect of cinnamic acid (CA) and cinnamaldehyde (CD) against cisplatin-induced nephrotoxicity. A single dose of cisplatin (5 mg/kg), injected intraperitoneally to male rats, caused significant increases in serum urea, creatinine levels, and lipid peroxides measured as the malondialdehyde content of kidney, with significant decreases in serum albumin, reduced glutathione, and the activity of antioxidant enzymes (catalase, su-peroxide dismutase, and glutathione peroxidase) of kidney as compared with the control group. On the other hand, administration of CA (50 mg/kg, p.o.) or CD (40 mg/kg, p.o.) for 7 days before cisplatin ameliorated the cisplatin-induced nephrotoxicity as indicated by the restoration of kidney function and ox-idative stress parameters. Furthermore, they reduced the histopathological changes induced by cisplatin. In conclusion, CA and CD showed protective effects against cisplatin-induced nephrotoxicity where CD was more effective than CA; affects that might be attributed to their antioxidant activities.
