[Abstract]  Traumatic brain injury (TBI) affects millions of people worldwide; however, the immediate impact of TBI and the secondary injury mechanisms are still not fully understood. TBI can cause devastating neuromotor deficits in both acute and chronic stages. Time course studies utilizing animal models of focal TBI have provided essential insight into TBI neuropathology. Here, we describe a surgical technique for creating a mouse model of focal, mild TBI (Dixon et al., 1991; Smith et al., 1995; Bolkvadze and Pitkanen, 2012). Furthermore, we provide protocols for validating TBI models using behavioral tests that examine post-traumatic neuromotor deficits resulting from TBI neuropathology (Fujimoto et al., 2004; Febinger et al., 2015; Smith et al., 1995; ... [摘要]  创伤性脑损伤(TBI)影响全世界数百万人; 然而,TBI和继发性损伤机制的直接影响仍然没有完全理解。 TBI可以在急性和慢性阶段引起毁灭性的神经性运动缺陷。 使用局灶性TBI动物模型的时程研究提供了对TBI神经病理学的重要见解。 在这里,我们描述了用于产生局灶性,轻度TBI的小鼠模型的外科技术(Dixon等人,1991; Smith等人,1995; Bolkvadze和Pitkanen, 2012)。 此外,我们提供用于验证TBI模型的方案,其使用行为测试,其检查由TBI神经病理学产生的创伤后神经运动缺陷(Fujimoto等人,2004; Febinger等人, 2015; Smith 等人,1995; Bolkvadze和Pitkanen,2012)。

[Abstract]  Stroke, the second leading cause of death worldwide (Ingall, 2004), is one of the major causes of morbidity and mortality. Intracerebral hemorrhage (ICH), a lethal type of stroke, accounts for 20% of all strokes (Qureshi et al., 2001), and occurs in about 50-60% of Asians (Inagawa, 2002). In order to understand the disease process, three animal model of ICH have been used to study the pathophysiology and treatment of ICH, including the microballoon model, the bacterial collagenase injection model (Rosenberg et al., 1990) and the autologous blood injection model (Andaluz et al., 2002; Belayev et al., 2003). In the collagenase injection model, the hemorrhage size is controllable which was induced by small vessel breakdown. This model also can mimic the ... [摘要]  中风是世界第二大死亡原因(Ingall,2004),是发病和死亡的主要原因之一。脑内出血(ICH)是致命型中风,占所有中风的20%(Qureshi等人,2001),并发生在约50-60%的亚洲人中(Inagawa,2002) 。为了理解疾病过程,已经使用ICH的三种动物模型来研究ICH的病理生理学和治疗,包括微球模型,细菌胶原酶注射模型(Rosenberg等人,1990)和自体血液注射模型(Andaluz等人,2002; Belayev等人,2003)。在胶原酶注射模型中,出血尺寸是可控的,其由小血管分解诱导。该模型还可以模拟自发性实质内出血的发作和ICH患者中持续出血的扩张(Kazui等人,1996; MacLellan等人,2008; James et al。,2008)。在过去几年中,我们以前的研究已经证明我们的修饰的胶原酶IV注射模型是大鼠中ICH的可靠且可重复的模型(Lu等人,2014; Gao等人, ,2014; Wang 等人,2011)。我们在此引入我们的ICH模型如下。
