🎯
Objective & Hypothesis:BACKGROUNDIn this experiment, the effects of lornoxicam on brain edema and the blood brain barrier (BBB) following diffuse traumatic brain injury (TBI) were studied.METHODSTwenty adult male Wistar albino rats were anesthetized, and experimental closed head trauma was induced by the Marmarou method.
📊
Key Findings & Data:After head injury, the rats were randomly divided into two groups: Group I was the control group, to which 2 ml saline was administered intraperitoneally, and Group II was the lornoxicam group, to which 2 ml 1.3 mg kg-1 lornoxicam was administered intraperitoneally.

Abstract

BACKGROUNDIn this experiment, the effects of lornoxicam on brain edema and the blood brain barrier (BBB) following diffuse traumatic brain injury (TBI) were studied.METHODSTwenty adult male Wistar albino rats were anesthetized, and experimental closed head trauma was induced by the Marmarou method. After head injury, the rats were randomly divided into two groups: Group I was the control group, to which 2 ml saline was administered intraperitoneally, and Group II was the lornoxicam group, to which 2 ml 1.3 mg kg-1 lornoxicam was administered intraperitoneally. Twenty-four hours after head trauma, 99 mTc pentetate (DTPA) was injected at a dose of 37 MBq, and posterior planar images of each rat were obtained using an Infinia gamma camera. After imaging of BBB permeability, brain tissues were dissected from the cranium. The brain water content (BWC) of each sample was calculated using the wet-dry method.RESULTSThe lesion/background (L/b) ratio of Group I was 3.76±0.46 and 3.02±0.66 for early (5th min) and late (60th min) imaging, respectively. In Group II, the L/b ratios were 3.52±0.96 and 2.63±0.63 for early and late imaging, respectively (p>0.05). BWC was 79.6±2.5% and 77.5±1.1% for Groups I and II, respectively (p<0.05).CONCLUSIONIn this rat model of TBI, lornoxicam reduced brain edema but did not affect BBB permeability.

Özet

AMAÇ Bu çalışmada diffüz travmatik beyin hasarı (TBH) sonrası, lornoksikamın kan beyin bariyeri (KBB) ve beyin ödemi üzerine etkileri araştırıldı.GEREÇ VE YÖNTEMYirmi erişkin erkek Wistar albino sıçana anestezi uygulaması sonrası Marmarou yöntemi ile deneysel kapalı kafa travması oluşturuldu. Kafa travması sonrası sıçanlar randomize olarak iki gruba ayrıldı: Grup I intraperitoneal yolla 2 mL salin uygulanan kontrol grubu ve Grup II intraperitoneal yolla 2 mL 1.3 mg kg-1 lornoksikam verilen lornoksikam grubu. Kafa travmasından 24 saat sonra 99 mTc pentetate (DTPA) 37 MBq dozda verildi ve her bir sıçanın posterior planar görüntüsü bir Infinia gama kamera kullanılarak elde edildi. KBB permebilitesinin görüntülenmesi sonrası beyin dokuları kranyumdan disseke edildi. Tüm örneklerin beyin su içeriği (BSI) ıslak-kuru metodu ile hesaplandı.BULGULARGrup I lesion/background (L/b) oranları erken dönem (5. dk) 3,76±0,46 ve geç dönem (60. dk) 3,02±0,66 idi. Grup II L/b oranları erken dönem 3,52±0,96, geç dönem 2,63±0,63 olarak saptandı (p>0,05). BSC Grup I’de %79,6±2,5 ve Grup II’de %77,5±1,1 idi (p<0,05).SONUÇBu TBH sıçan modelinde lornoksikamın beyin ödemini azalttığı ancak KBB geçirgenliğini etkilemediği görülmüştür.
