Abstract

AIM: In this study, the effects of lornoxicam on the prevention of secondary brain injury via the apoptotic pathway were studied in a rat model of head injury. MATERIAL and METHODS: Thirty adult male Wistar albino rats were anesthetized, and experimental closed head trauma was induced by allowing a 450 g weight to fall two meters onto a metallic disk fixed to the intact skull. After head injury, the rats were randomly divided into two groups: Group I (n=15) rats were administered 2 mL saline intraperitoneally (controls); Group II (n=15) rats were administered 2 mL 1.3 mg kg-1 lornoxicam intraperitoneally. Brain tissue samples were divided into two pieces by interhemispheric incision for biochemical and histological analysis. results: TUNEL positivity was seen in neuroglia cells of the brain cortex in both groups. While the immunoreactivities of caspase 8, 9 and Fas/ Fas ligand were similar in both groups, the immunoreactivity of caspase 3 was greater in Group I than Group II. MDA was significantly lower in Group II than in Group I (p<0.05). The decrease in SOD level was higher in Group I than Group II. CONCLUSION: Lornoxicam did not prevent apoptosis in this rat model of brain trauma but causes a decrease.

Özet

AMAÇ: Bu çalışmada, lornoksikamın sekonder beyin hasarını önlemede, kafa travmalı bir rat modelinde apoptotik yollar aracılı etkileri araştırıldı. YÖNTEM ve GEREÇLER: Otuz erişkin Wistar albino rata anestezi uygulaması sonrası kafatası üzerine konan bir metal disk üzerine 2 metreden 450 g ağırlık düşürülerek deneysel kapalı kafa travması oluşturuldu. Travma sonrası ratlar randomize olarak 2 gruba ayrıldı; Grup Ie (n=15) intraperitoneal yolla 2 mL salin, Grup II (n=15) intraperitoneal yolla 2 mL 1.3 mg kg-1 lornoksikam verildi. Beyin dokuları biyokimyasal ve histolojik incelemeler için interhemisferik kesi ile ikiye ayrıldı. BULGULAR: TUNEL pozitifliği her iki grupta beyin korteks nöroglia hücrelerinde görüldü. Her iki grupta kaspaz 8, 9 ve Fas/Fas ligand immünoreaktivitesi normalken, kaspaz 3 immünoreaktivitesi Grup Ide Grup IIden daha yüksekti. MDA Grup IIde Grup Iden daha düşüktü. SOD düzeyindeki azalma Grup Ide, Grup IIden daha fazlaydı. SONUÇ: Lornoksikam bu beyin travması rat modelimizde apoptozisi önlememiş ancak bir azalma sağlamıştır.
