Abstract:Despite the diverse applications ofγradiation in radiotherapy, industrial processes, and sterilization, it causes hazardous effects on living organisms, such as cellular senescence, persistent cell cycle arrest, and mitochondrial dysfunction.这项研究评估了姜黄素纳米颗粒(CNP)在减轻线粒体功能障碍和细胞SEN的功效大鼠脑组织中γ诱导的升高。包括四组男性Wistar白化大鼠(每组n = 8):(GR1)对照组; (GR2)CNPS组(健康大鼠接受口服姜黄素纳米颗粒的剂量为10 mg/kg/day,每周三次,持续八周); (gr3)受辐射的组(暴露于10 Gy头γirradiation的大鼠); (GR4)受照射的+CNPS组(用CNP处理的受辐照大鼠)。 The data obtained demonstrated that oral administration of CNPs for eight weeks attenuated oxidative stress inγ-irradiated rats by lowering the brains lipid peroxidation level [malondialdehyde (MDA)] and enhancing antioxidant markers [superoxide dismutase (SOD), reduced glutathione (GSH), and total antioxidant capacity (TAC)] (P < 0.05).此外,与辐照组相比,CNP通过改善复合物I,复合物II和ATP产生水平来显着提高线粒体功能。在受辐照的大鼠中,CNP也SHO通过降低脑白介素6(IL-6),肿瘤坏死因子-Alpha(TNF-α)和核因子-KAPPA B(NF-ĸB)水平(p <0.05)来降低抗神经炎症的影响。此外,与受辐照的大鼠施用的CNP显着降低了脑β-半乳糖苷酶活性以及p53,p21和p16基因的表达水平(P <0.05),同时同时诱导与辐照组相比,AMPK mRNA表达的显着增加。总之,CNP可以改善γ辐射的神经毒性,并成为一种新颖的诺言,可以通过其合并的抗氧化剂,抗炎和线粒体增强特性来延迟细胞衰老的新手。
