摘要:

目的 建立并优化花生四烯酸诱导的大鼠弥漫性脑血栓模型。方法 经颈内动脉注射花生四烯酸,建立大鼠弥漫性脑血栓模型;同时设定假手术组作为对照。通过检测脑组织中伊文思蓝(Evans blue,EB)渗出含量以及HE染色法检测脑组织病理损伤程度评价建模效果。结果 与假手术组相比,模型组大鼠损伤侧脑组织中均出现弥漫性EB渗出(P<0.01),且渗出情况均一性较佳。损伤侧脑组织病理表现为细胞排列混乱,细胞核皱缩,细胞间隙增大,空泡细胞增多,个别微血管呈红色条形管型的缺血病理损伤。结论 花生四烯酸可成功诱导弥漫性脑血栓模型,且优化方法后模型稳定性较好,死亡率较低。

Abstract:

Objective Establishment and optimization of arachidonic acid-induced diffuse cerebral thrombosis model in rats.Methods Arachidonic acid was injected into the internal carotid artery to establish a diffuse cerebral thrombosis model in rats, while the sham operation group was set as the control. The model was evaluated by detecting the exudate content of Evans blue (EB) in brain tissue and the pathological damage degree of brain tissue by HE staining.Results Compared with the sham operation group, diffuse EB exudation was observed in the injured brain tissue of the model group (P < 0.01), and the exudation was relatively uniform. The HE staining of brain tissue on the side of the injury showed ischemic pathological damage with disorganized cell arrangement, wrinkled nuclei, enlarged cell gaps, increased vacuolated cells, and red striped tubular shape of each individual microvessel.Conclusion Arachidonic acid can successfully induce diffuse cerebral thrombosis model, and the optimized model has better stability and lower mortality.
