检验原理麻疹病毒酶联免疫吸附测定法

用抗原包被微量板孔，制成固相载体。加患者血清到板孔中，其所含的抗体特异性地与固相载体中现存抗原结合，形成免疫复合物。除去多余物质后，加入结合了碱性磷酸酶的IgG、IgA或IgM抗体，使之与上述免疫复合物反应。洗板，除去多余的结合物，加入底物（对硝基苯磷酸盐）。其与酶结合的免疫复合物反应，产生有颜色产物，颜色强度与特异性抗体含量成正比。

产品规格：96T/盒

新小脑的损伤，将使受害者的肌紧张减退和随意运动的 协调性紊乱，称为小脑性共济失调。主要的表现有：①运动的准确性 发生障碍。产生意向性震颤现象，当病人留意做某动作，如用手指鼻 时，手指发生颤抖，愈接近目标，手指颤抖得愈厉害，细菌而不能把 握运动的准确方向。②动作的协调性发生障碍。患者丧失使一个动作 停止而立即转换为相反方向的动作的能力，运动时动作分解不连续。 例如，病人不能完成快速翻转手掌这类简单、快速的轮替运动，称为 轮替运动失常；当完成一个方向的运动并需要转换运动的方向时，患 者必须先停下来思考下一步的动作，才能再重新开始新的运动。所有 这些列举的症状只在运动中表现出来，说明新小脑对随意运动起着重 要的协调作用，这种协调作用，是小脑对大脑皮层和脊髓活动进行调 节的结果。在大脑皮层与小脑之间存在着双向的神经连接，大脑皮层 发出传导运动信息的锥体束在下行过程中，有侧枝在桥脑的脑桥核换 神经元，再由脑桥核发出纤维进入小脑，形成皮层—脑桥小脑束；而 小脑向大脑皮层的投射，由新小脑皮层的浦肯野氏细胞的轴突投射到 深部的齿状核，再由齿状核发出纤维出小脑，经丘脑腹外侧核到达大 脑皮层的运动区，这就是齿状核—丘脑皮层束，这两条传导束构成了 小脑调节大脑皮层运动区活动的基本环路。当大脑皮层运动区将引起 肌肉收缩的运动冲动经锥体束传向脊髓的时候，也同时有侧枝冲动经 皮层—脑桥小脑束到达小脑。有关的肌肉在接受到这些运动冲动而发 生收缩时，肌肉中的肌梭等本体感受器又将它们所感受的有关肌肉运 动的本体冲动，经脊髓小脑束传入小脑。这样，在随意运动进行的每 一瞬间，小脑即接受到大脑皮层给出的引起运动的指令，又获取了肌 肉执行运动指令的信息。在对两者进行比较之后，小脑皮层的浦肯野 氏细胞发出的冲动对小脑深部核团，主要是齿状核的活动进行调整， 再由齿状核发出冲动经齿状核—丘脑皮层束反馈到大脑皮层运动区， 通过易化或抑制作用相应地调整了大脑皮层运动区的活动。
The damage of the new cerebellum, will make the victims of muscle tension and coordination of voluntary movement disorder, known as cerebellar ataxia. The main performance are: ① the accuracy of the movement obstacles. Intent-induced tremor phenomenon, when the patient pays attention to do some action, such as finger nose, the fingers tremble, the closer the target, the greater the trembling fingers, bacteria and can not grasp the exact direction of movement. ② the coordination of the action obstacles. The patient loses the ability to immediay stop one movement and change it to an opposite movement, and the movement breaks down discontinuously. For example, a patient can not complete a simple, rapid rotation of a hand, such as a quick flip of the palm, called a rotation disorder; when completing a one-directional motion and needing to translate the direction of the motion, the patient must first stop to think about the next motion, Can we start a new sport again. All of these listed symptoms are exhibited only during exercise, indicating that the new cerebellum plays an important coordinating role for voluntary exercise as a result of the cerebellum's regulation of cerebral cortex and spinal cord activity. In the cerebral cortex and the cerebellum there is a two-way neural connection, the cerebral cortex sends a cone motion information transmission cone beam in the process of descending, there are collateral pons in the pons and pons for the replacement of neurons, and then issued by the pontine fiber into the cerebellum, The formation of cortical - cerebellopontine bundle; and cerebellum projection to the cerebral cortex, the new cerebellar Purkinje cell axon projection to the deep dentate nucleus, and then sent out by the dentate nucleus out of the cerebellum, the hypothalamic ventrolateral The nucleus reaches the motor region of the cerebral cortex, which is the dentate nucleus - thalamic cortex bundle, which form the basic loop of the cerebellum's activity in regulating the motor cortex. When the motor cortex of the cerebral cortex will cause the contraction of the motor movement impulses transmitted through the pyramidal tract to the spinal cord, but also collateral impulses through the cortex - pontine cerebrum bundle to the cerebellum. When the muscles involved contract and contract with these impulsive movements, the somatosensors such as the muscle spindles in the muscles in turn impulse the bodies they feel about muscle movement to transmit through the spinocerebellar fasciculus to the cerebellum. In this way, at each moment of voluntary exercise, the cerebellum receives instruction given by the cerebral cortex to initiate exercise and acquires information on muscle exercise instructions. After comparing the two, the impulses of Purkinje cells in the cerebellar cortex modulate the activity of the deep nuclei of the cerebellum, mainly the dentate nucleus, and the odontoid nucleus then impulses through the dentate nucleus - thalamic cortex bundle Feedback to the motor area of ​​the cerebral cortex, through the facilitation or inhibition of the corresponding adjustments in the motor area of ​​the cerebral cortex activity.
