BACKGROUND/AIM: The present study investigated the neuroprotective effects of chrysin (CRS) following global cerebral ischemia and reperfusion (I/R) in a C57BL/J6 mouse model.
A total of 40 mice were equally divided into four groups: (1) sham-operated (SH = control), (2) global cerebral I/R (I/R), (3) CRS, and (4) CRS + I/R. In the I/R group, the bilateral carotid arteries were clipped for 15 min and the mice were treated with vehicle (corn oil) for 10 days. In the CRS group, CRS (50 mg/kg) was given for 10 days without carotid occlusion. In the CRS + I/R group bilateral carotid arteries were clipped for 15 min and the mice were also treated with CRS (50 mg/kg) for 10 days. All of the rats were sacrificed under anesthesia on day 10, and neurodegenerative histological changes in the brain and tissue levels of oxidants and antioxidants were evaluated.
CRS treatment significantly reversed the oxidative effects of I/R and inhibited the development of neurodegenerative histopathologies. In the CRS + I/R group, the decrease in TBARS levels and increase in GSH levels were similar to those in the SH group.
Treatment with CRS can positively affect the neural system of mice and it can be used for the treatment of global cerebral I/R.
背景/目的:本研究旨在探讨白杨素(CRS)在 C57BL/J6 小鼠全脑缺血再灌注(I/R)模型中对神经的保护作用。
将 40 只小鼠等分为 4 组:(1)假手术组(SH = 对照组);(2)全脑 I/R 组(I/R);(3)CRS 组;(4)CRS + I/R 组。在 I/R 组中,夹闭双侧颈总动脉 15 分钟,并用玉米油处理小鼠 10 天。在 CRS 组中,不夹闭双侧颈总动脉,用 CRS(50mg/kg)处理小鼠 10 天。在 CRS + I/R 组中,夹闭双侧颈总动脉 15 分钟,并用 CRS(50mg/kg)处理小鼠 10 天。所有大鼠均在第 10 天麻醉下处死,评估脑内神经退行性组织学变化和组织中氧化剂和抗氧化剂的水平。
CRS 治疗显著逆转了 I/R 的氧化作用,并抑制了神经退行性组织病理学的发展。在 CRS + I/R 组中,TBARS 水平的降低和 GSH 水平的升高与 SH 组相似。
CRS 治疗可对小鼠的神经系统产生积极影响,可用于治疗全脑 I/R。
