缺血性中风给世界各地的个人、家庭和社会带来越来越大的负担。然而,缺乏针对缺血性中风的有效疗法或药物。因此,模拟人类缺血性中风的动物模型对于临床前实验具有重要价值。小鼠或大鼠大脑中动脉闭塞(MCAO)以及随后对脑切片进行 2,3,5-三苯基氯化四唑(TTC)染色是实验动物缺血性中风研究的常用方法。在这项研究中,我们介绍并评估了 TTC 染色 (SAT) 软件程序的半自动分析的实用性,这是一种新颖、小型、用户友好的免费软件程序,通过分析手机或扫描系统捕获的图像,使用 TTC 染色量化啮齿动物脑切片中的梗塞大小。我们对成年小鼠进行了 MCAO 和 TTC 染色。然后,我们利用 SAT 软件和 Image J 通过 TTC 染色分析脑切片中的梗塞大小,并比较两种分析方法的结果。我们发现 SAT 和 Image J 的梗死面积数据具有可比性,这表明 SAT 软件可以作为评估缺血性中风时 Image J 的替代选择。
Ischemic stroke places an increasing burden on individuals, families, and societies around the world. However, effective therapies or drugs for ischemic stroke are lacking. Therefore, animal models mimicking ischemic stroke in humans are of great value for preclinical experiments. middle cerebral artery occlusion (MCAO) in mice or rats and subsequent 2,3,5-triphenyltetrazolium chloride (TTC) staining of brain sections are common methods in the study of experimental animal ischemic stroke. In this study, we present and assess the utility of the semi-automated analysis of the TTC staining (SAT) software program, a novel, small, user-friendly, and free software program, in the quantification of the infarct size in rodent brain sections, with TTC staining, by analyzing images captured by cell phones or scan systems. We performed MCAO and TTC staining in adult mice. We then utilized the SAT software and Image J to analyze the infarct size in the brain sections with TTC staining and compared the findings of the two analysis methods. We found that the data on infarct size from SAT and from Image J were comparable, suggesting that the SAT software could be an alternative option to Image J in the evaluation of ischemic stroke.
