  • Cerebrovascular disease is a group of diseases that seriously endanger human health and has become one of the important causes of human disability and death.
  • Cerebrovascular disease refers to brain lesions caused by abnormalities in cerebrovascular diseases. Stroke refers to acute cerebrovascular disease.
  • Cerebrovascular diseases can be easily divided into two categories, one is ischemic cerebrovascular disease caused by decreased blood flow or interruption, and the other is hemorrhagic cerebrovascular disease caused by rupture of blood vessels.
  • Ischemic cerebrovascular disease is mainly cerebral infarction (including cerebral thrombosis and cerebral embolism). In addition to cerebral infarction, there is an ischemic cerebrovascular disease that can be completely recovered within 24 hours without any sequelae.
  • TIA transient ischemic attack or transient ischemic attack, doctors are used to refer to TIA for short, also known as small stroke.
  • Hemorrhagic cerebral vascular disease is also divided into two categories, one is the rupture of blood vessels, and the blood flows into the brain parenchyma, called cerebral hemorrhage or cerebral hemorrhage. The other type is the rupture of blood vessels.
  • the blood flows around the subarachnoid space around the brain, called subarachnoid hemorrhage.
  • the doctor is referred to as SAH.
  • 3-mercapto-1-phenyl-2-pyrazoline-5-one also known as edaravone, has the structural formula
  • 3-mercapto-p-phenyl-2-pyrazol-5-one is a brain protectant that scavenges free radicals and inhibits lipid peroxidation, thereby inhibiting oxidative damage of brain cells, vascular endothelial cells, and nerve cells.
  • Intravenous edaravone in rats after ischemia/ischemia reperfusion can prevent the progression of cerebral edema and cerebral infarction, relieve the accompanying neurological symptoms, and inhibit delayed neuronal death.

1.3.1 局灶性脑缺血再灌注模型制备。 主要步骤: 10 %水合氯醛 ( 350mg/kg )腹腔注射麻醉大鼠, 分离、 结扎并切断右侧颈外动脉, 由颈外动 脉残端沿颈总和颈内动脉緩慢插人头端膨大的尼龙栓线约 18mm, 阻塞大脑中 动脉入口造成缺血。 缺血 2h (小时 )后拔除栓线进行 24h再灌注; £手术组 栓线只分离血管, 其余步骤同模型组。 动物苏醒后出现 Homer征和对侧体运 动障碍即为模型制备成功。
1. 3. 2 动物分组与给药 实验动物随机分为 5组, 即假手术组、模型组 和药物组。 实验动物于缺血前 30min (分钟 )和再灌注后 12h 两次腹腔注射受 试药物, 假手术组和模型组分别注射等容积的生理盐水。
1. 3. 3 神经缺陷评分、 脑梗塞体积及脑组织含水量的测定
神经缺陷评分,按照 Longa 5分制评分标准于再灌注后 24h进行行为学评 分。
脑梗死体积测定,动物经末次神经功能缺损评分后,断头取脑。剔除嗅脑、 低位脑干及小脑, 剩余部分立即称取湿重,在水上将脑沿冠状面切成厚度基本 相同的 5片, 于 37°C红四氮唑染料中温浴 30min, 正常脑组织呈玫瑰红, 梗死 区呈现白色。 然后将脑片置 10%的曱醛中固定, 将白色组织仔细挖下称重, 以 梗死组织重量占总脑重量的百分比作为梗死体积判定指标。
脑含水量测定, 用干湿法测定脑含水量。 动物处死后, 取出全脑, 去除嗅 脑、 低位脑于及小脑, 立即称取脑湿重, 置 120°C的烤箱中烘烤约 18 h后称取 干重。 脑含水量按下列公式计算: 脑含水量(%)= (脑湿重一脑干重) /脑湿重 χ 100。
2 结果
2.1 对缺血再灌注后脑梗塞体积和神经缺陷评分的影响

1. 3 方法 1.3.1 局灶性脑缺血再灌注模型制备: 釆用颈内动脉线栓法制备大脑中 动脉阻塞( Middle cerebral artery, MCAO )脑缺血再灌注模型。 动物用 10 %水 合三氯乙醛(3.5ml/kg )麻醉后, 俯卧位固定于手术台上, 消毒皮肤, 颈部正 中切开, 分离右侧颈总动脉、 颈外动脉、 颈内动脉, 轻轻剥离迷走神经, 结扎 并剪断颈外动脉, 循颈内动脉向前, 结扎翼腭动脉。 夹闭颈总动脉近心端, 从 颈外动脉的结扎线的远端作一切口, 插入外径为 0.285mm (毫米) 的尼龙线, 进过颈总动脉分叉进入颈内动脉, 然后徐徐插入至有轻微阻力为止(自分叉处 约 20mm ), 阻断大脑中动脉的所有血供, 用激光多普勒脑血流仪监测脑血流, 右侧脑缺血 2.0h后, 轻轻拔出尼龙线, 恢复血供进行再灌注, 缝合头皮, 消 毒。 支手术组仅分离血管, 不插入尼龙线。 整个手术使用大鼠加热板和 60W (瓦) 的台灯维持大鼠的体温 37.0士 0.5°C。
1. 3. 2 动物分组与给药 实验动物随机分为 6组, 即假手术组、 模型 组、 阳性对照组和药物组(依达拉奉 +天然水片给药总剂量为 0.75mg/kg )。 实 验动物制备脑缺血模型后,将动物按机率均等单盲分配至各组。 于脑缺血后立 即给药 1次, 以后每分别于 2、 4、 24小时给药一次,共给药 4次。 模型组: 给 大鼠尾静脉注射等体积的生理盐水。假手术组给大鼠尾静脉注射等体积的生理 盐水。 阳性对照组尼莫地平注射液作为阳性对照, 1.2mg/kg, 共给药三次, 单 次给药剂量为 0.4 mg/kg0
1. 3. 3 神经缺陷评分、 脑梗塞体积的测定
神经缺陷评分, 釆用改良 Bederson 5分制法进行神经缺陷症状评价。釆用 单盲法评价脑外伤后大鼠的神经缺陷症状, 即由试验设计者将动物按组标记, 对神经缺陷症状进行评分的试验者不知道动物的分组情况,评分结束后, 评分 者将各种标记的评分结果呈交设计者, 由设计者揭盲, 获得各试验组每只动物 的评分。
神经缺陷症状评分 Bederson 5分制法的具体标准为:
0: 提尾悬空时, 动物的两前肢均伸向地板方向, 且无其他行为缺陷 1 : 提尾悬空时, 动物的手术对(左)侧前肢表现为腕肘屈曲、 肩内旋、 肘外展、 紧贴胸壁
2: 将动物置于光滑平板上, 推手术侧肩向对侧移动时阻力降低 3: 动物自由行走时, 向手术对侧环行或转圈
4: 肢体软瘫, 肢体无自发活动
脑梗死面积和脑损伤测定, 动物用 10 %的水合氯醛麻醉, 断头取脑, 去 除嗅球、小脑和低位脑干,用生理盐水冲洗大脑表面血迹,吸去表面残留水迹, 于- 80°C放置 7min, 取出后立即于视线交叉平面垂直向下作冠状切面, 并向 后每隔 2mm切一片, 将脑片置于用 0.2 mol/L (摩尔 /升 ) H 7.4 ~ 7.8 PBS新 鲜配制的 20 g/L TTC染液中水浴 (37 °C 90min), 正常脑组织染成深红色, 缺血 脑组织则呈苍白色,用生理盐水冲洗后,迅速将脑片从前向后按顺序排成一排, 吸干表面残留水迹,拍照,分离左右脑组织分别称其脑重 W左(左脑重量) 和 W右 (右脑重量) , 向左右脑组织中各加入新鲜配置的提取液( DMSO (二 曱基亚砜): 乙醇( 1 : 1 ) 15毫升, 于 25°C , 避光 24小时, 充分提取生成的 红色物质曱月替, 至脑片呈白色。
1.用图像分析软件对照片进行统计, 圈定右侧缺血面积(白色区域)和右 侧总面积, 用如下公式计算脑梗死面积的百分比。
缺血总面积
梗死面积% = 100 X 右侧总面积
2.于 485nm (纳米)处分别测定提取物的吸光度(提取物 ΙΟΟμΙ (微升) +提取液 1900μ1 ), 测定四次, 取其均值, 得 Α左 和 A右 。 用如下公式计算 脑损伤程度的百分比。 脑损伤% = 100 χ ( 1 - Α左 右 )
1. 3. 4统计学分析
定量资料表示为均值士标准差。 脑梗死面积、 神经缺陷症状评分釆用单因 素方差分析, Scheffe' s检验测定两组间的差异显著性。动物死亡率的组间比较 釆用 X2检验, 将差异 PO.05定义为差异显著。
