Traumatic Brain Injury (TBI) is widely acknowledged as a significant risk factor for death and disability. Our goal in this experiment was to see if Auraptene (AUR) could help rats recover from TBI-induced disability by measuring of oxidative stress parameters.
Adult male Wistar rats were randomly assigned to one of six groups: sham, TBI, Vehicle (DMSO), TBI+ AUR (4 mg/kg), TBI + AUR (8 mg/kg), TBI + AUR (25 mg/kg). The animals were anesthetized. After that, diffuse TBI was done by Marmarou model in male rats. Then, the brain tissues were harvested. Some of oxidative stress parameters, and TNFα levels were evaluated.
TBI-induced brain damage was significantly inhibited by AUR (25 mg/kg), as evidenced by decreased Malondialdehyde (MDA) and Nitric Oxide (NO) levels, oxidative stress inhibition and reduced levels of pro-inflammatory cytokine tumor necrosis factor (TNF-α) in the brain.
This study showed that probably the AUR prevents complications of TBI through decreases in brain edema, modulating oxidative stress, and reductions in the levels of inflammatory cytokines.
创伤性脑损伤(TBI)被广泛认为是导致死亡和残疾的重要危险因素。本实验旨在通过测量氧化应激参数,观察 Auraptene(AUR)是否能帮助 TBI 诱导的残疾大鼠恢复。
成年雄性 Wistar 大鼠随机分为六组:假手术组、TBI 组、载体(DMSO)组、TBI+AUR(4mg/kg)组、TBI+AUR(8mg/kg)组、TBI+AUR(25mg/kg)组。动物麻醉后,雄性大鼠采用 Marmarou 模型进行弥漫性 TBI。然后采集脑组织,评估部分氧化应激参数和 TNFα 水平。
AUR(25mg/kg)显著抑制 TBI 诱导的脑损伤,表现为脑 MDA 和 NO 水平降低,氧化应激抑制,促炎细胞因子肿瘤坏死因子(TNF-α)水平降低。
本研究表明,AUR 可能通过减轻脑水肿、调节氧化应激和降低炎症细胞因子水平来预防 TBI 的并发症。
