Abstract
Aim: In a former study, we have showed that CAPE has preventive effect on cisplatin-induced nephrotoxicity. In this study we re-analyzed the renal tissues of the rats used formerly and investigated whether cisplatin has any effects on hexokinase (UK), glucose-6-phosphate dehydrogenase (G6PD), lactate dehydrogenase (LDH) and malate dehydrogenase (MDH) enzyme activities in renal tisssues, and the possible preventive role of CAPE on this effect. Methods: The study was performed with 22 rats in 3 main groups: group I (n=6): 0.9% saline solution was applied to the rats intraperitoneally (i.p.); group II (n=9): 7 mg/kg single dose cisplatin was administered i.p.; and group III (n=7): 10/umol/kg from lOftmol/ml CAPE solution was administered daily 1x1 begining 2 days before cisplatin administration. At the /7th day of treatment, the rats were killed by decapitation under anesthesia, autopsied and their kidney tissues were removed. Spectrophotometric methods were used to determine the activities of above-mentioned enzymes in the kidney tissue. Results: The results of the experiment demonstrated that HK and G6PD activities were increased significantly in the cisplatin group compared with the control group (p<0.05). The most increase of HK was seen in the CAPE group. CAPE prevented the increases of G6PD activities nonsignificantly (p>0.05). LDH activity was increased significantly in the CAPE group compared with cisplatin group or the control group (p<0.05). Cisplatin did not affect solely the LDH activity (p>0.05). There was no significant difference in the LDH activity between cisplatin and control groups, and nor in the MDH activities among cisplatin, CAPE, and control groups (p>0.05). Conclusion: From these results, it can be concluded that the activities of enzymes playing role in carbohydrate metabolism like HK and G6PD may increase in the course of cisplatin-induced nephrotoxicity process.
Özet
Amaç: Daha önceden yaptığımız çalışmada sisplatin nefrotoksitesi üzerine kafeik asit fenetil ester'in (CAPE) koruyucu etkisi olduğu gösterilmiştir. Bu çalışmada, daha önceki çalışmamızda kullanılan sıçanların böbrek dokuları yeniden analiz adildi ve sisplatinin böbrek dokusunda hekzokinaz (HK), glukoz-6-fosfat dehidrogenaz (G6PD), laktat dehidrogenaz (LD1I) ve m a la t dehidrogenaz (MDH) enzim aktiviteleri üzerine etkisi ve buna CAPE'nin koruyucu etkisi araştırıldı. Metod: 22 adet sıçan üç gruba ayrıldı. Grup-I (n=6): sadece intraperitoneal izotonik NaCl; Grup-II (n=9): tek dozda 7 mg/kg sisplatin ve Grup-III (n=7): sisplatin uygulamasından 2 gün önce başlamak üzere CAPE lOfimol/kg 1x1 intraperitoneal yolla 7 gün verildi. Yedinci gün anestezi altında dekapite edilerek öldürülen sıçanların böbrek dokuları alındı. Böbrek dokusunda hekzokinaz (HK), glukoz-6-fosfat dehidrogenaz (G6PD), laktat dehidrogenaz (LDH) ve malat dehidrogenaz (MDH) aktiviteleri spektrofotometrik olarak ölçüldü. Bulgular: Sisplatin böbrek dokusunda HK ve G6PD aktivitelerinde kontrol grubuna göre anlamlı bir artmaya neden oldu (p 0.05). CAPE verilen sıçanlarda kontrol ve sisplatin grubuna göre LDH aktivitesinde anlamlı bir artma bulundu (Sırasıyla, p 0.05). Üç grupta da MDH aktivitesi değişmedi (p>0.05). Sonuç: Sisplatinle hasarlanmış böbrek dokusunda, HK ve G6PD enzimi gibi karbonhidrat metabolizmasında rolü olan enzimlerin aktivitelerinin artabileceği gösterilmiştir.
