中文摘要:

目的观察异甘草素对创伤性脑损伤大鼠神经功能的影响。方法先对大鼠建立脑损伤模型,按随机数字表法随机分成假手术组、脑损伤组、异甘草素组,假手术组、脑损伤组予等量0.9%氯化钠注射液灌胃,异甘草素组予20 mg/kg药物灌胃治疗,1周后处死,均终点法检测过氧化物歧化酶(SOD)、丙二醛(MDA)、酶联免疫吸附法测白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)含量,观察在以上指标变化情况。结果异甘草素组SOD、MDA、Feeney评分、TNF-α、IL-1α、IL-1β、IL-6、IL-10分别为(123.77±9.35)U/mg、(3.27±1.15)U/mg、(2.12±0.43)分、(38.74±2.35)pg/mg、(106.24±9.13)pg/mg、(83.46±7.24)pg/mg、(367.69±36.13)pg/mg、(417.35±25.35)pg/mg,和其他两组比较差异有统计学意义(P〈0.05);在组织形态学上,表现为脑皮层损伤灶细胞数明显增多,伤口肉芽组织填平,软脑膜已经形成,且和正常脑组织入脑膜相续,半透明水肿带交窄,水肿带局限在损伤灶底部,与其他组比较差异有统计学意义(P〈0.05)。结论异甘草素能保护创伤性脑损伤大鼠神经功能,可能和降低氧化应激和调节脑组织细胞因子有关。

英文摘要:

Objective: To investigate isoliquiritigenin of traumatic brain injury in rats with nerve function. Meth- ods: First, the establishment of brain injury in rats were randomly divided into sham group, brain injury group, Isoliquiritigenin group,sham operation group,brain injury group were fed with normal saline,Isoliquiritigenin group I 20 mg/kg of drugs gavage treatment.One week after the death, rats were detected by ultra-manifold end peroxidase (SOD) ,malondialdehyde (MDA),enzyme-linked immunosorbent assay of interleukin (IL-α),tumor necrosis factor(TNF-α) content to observe the changes in these indicators. Results: Isoliquiritigenin group SOD, MDA,IL-6,TNF-α,respectively (123.77±9.35) U/mgprot, (3.27±1.15) U/mgpro, (367.69±36.13) pg/mg, (38.74±2.35) pg/mg,and the other two groups was statistically significant difference (P〈 0.05);in the tissue mor- phology,the number of tumor cells in the brain showed significantly increased cortical injury,wound granulation tissue filled,pia mater had been formed,and and normal brain tissue into the meninges phase continued,cross narrow translucent edema,edema lesions confined to the bottom of the injury. And other differences were statisti- cally significant (P 〈 0.05). Conclusion: Isoliquiritigenin can protect nerve injury in rats with traumatic brain function, which may he related to reducing oxidative stress and regulating brain cytokines.
