چکیده انگلیسی
Cisplatin (CP) is a widely used antineoplastic agent which exhibits gastrointestinal toxicity. The present work was done to study the effect of administration of CP on brush border membrane (BBM) enzymes and anti-oxidant system of rat intestine. Male Wistar rats were given a single intraperitoneal dose of CP (6Â mg/kg body weight) and then sacrificed 1, 3, 5 and 7Â days after this treatment. Control animals were given saline only. The administration of CP led to significant decline in the specific activities of BBM enzymes both in the mucosal homogenates and isolated membrane vesicles. Kinetic studies showed that the Vmax of the enzymes was decreased in BBM vesicles from CP treated rats while the Km remained unchanged. The activities of catalase, Cu-Zn superoxide dismutase, glucose 6-phosphate dehydrogenase and glutathione reductase decreased while the activities of glutathione S-transferase and thioredoxin reductase increased in CP treated animals compared to the control group. Lipid peroxidation and total sulfhydryl groups were also altered upon CP treatment indicating the generation of oxidative stress. The maximum changes in all the parameters studied above were 3Â days after administration of CP and then recovery took place on days 5 and 7. Thus, the administration of CP leads to significant alterations in the activities of BBM enzymes and the anti-oxidant status of rat intestine.
