The activities of liver adenosine deaminase, xanthine oxidase, catalase, superoxide dismutase enzymes and the levels of malondialdehyde and nitric oxide after cisplatin toxicity in rats: protective effect of caffeic acid phenethyl ester.
The aim of this experimental study was to investigate the effects of caffeic acid phenethyl ester (CAPE), an antioxidant agent, on cisplatin-induced hepatotoxicity through adenosine deaminase (AD), xanthine oxidase (XO), catalase (CAT), superoxide dismutase (SOD) activities and malondialdehyde (MDA) and nitric oxide (NO) levels in liver tissue of rats. Wistar albino rats were divided into three groups: control group (n = 6), cisplatin group (n = 9) and CAPE + cisplatin group (n = 8). All the chemicals used were applied intraperitoneally. Spectrophotometric methods were used to determine the activities of the above-mentioned enzymes in the liver tissue. NO level and XO activity were found to be increased in the cisplatin group compared to the control group. NO level was found to be decreased in the cisplatin + CAPE group in comparison with the cisplatin group. There was no significant change in the activity of XO between the cisplatin and cisplatin + CAPE groups. The activity of SOD was lower in the cisplatin group than both the control and cisplatin + CAPE groups. There was no significant change in the activity of CAT between the control and cisplatin groups. CAT activity was increased in the cisplatin + CAPE group compared to the cisplatin group. The AD activity and MDA level remained unchanged in all groups. The results obtained suggested that CAPE significantly attenuated the hepatotoxicity as an indirect target of cisplatin in an animal model of cisplatin-induced nephrotoxicity.
