显微注射肌肉神经阻断剂——肉毒杆菌毒素可治疗痉挛性发声障碍。但此药毒性甚剧,因此要求准确而小量的注射至运动终板处。本文将以计算机成像的方法,根据运动终板处乙酰胆碱酯酶活性最高而染色最深的原理,立体地研究了三只猫和一个人新鲜尸体的甲杓肌中运动终板的分布情况。结果见人和猫近似。一般肌肉(包括环甲肌)的运动终板呈束状的位于肌腹中点处,而甲杓肌肉的运动终板却是散乱地遍布于整块肌肉中。提示在注射肉毒毒素时不能简单地只注射于中点处,而宜多注射几个点以使声带充分麻痹。另外,作者们在假声带里也发现了不少的运动终板。根据近年来见到喉上神经内支中有不少 Microinjection of Muscle Nerve Blocker - Botulinum Toxin to Treat Spasmodic Dyslexia. However, this drug is very toxic and therefore requires accurate and small injection to the motor end plate. In this paper, the distribution of motor end plate in the muscle of three cats and one human fresh corpse will be studied stereoscopically based on the principle of computer imaging and the deepest staining of AChE at the motor endplate. The results see people and cat approximation. General muscle (including circumcised muscle) end of the motor was a bundle of muscle in the midpoint of the belly, while the muscle side of the muscle A scoop muscles are scattered throughout the muscle in the whole piece. Tip botulinum toxin injection can not be simply injected at the midpoint, and should be injected a few more points in order to make full vocal paralysis. In addition, the authors found a lot of motor end boards in the falsetto. According to the laryngeal nerve in recent years to see there are many
