目的试图建立光镜下突触可塑性研究新的可靠的染色方法。方法采用人或大鼠的肌肉标本固定、切片，借助组化方法建立运动终板染色法。结果本染色法能同时显示肌肉、运动终板及运动神经终末结构，并能定量各种神经末梢发芽。结论本文建立了新的神经肌肉接头染色法。本法省时、操作简单方便、重复性好，为同类研究提供了一个良好的方法。） Objective To establish a new and reliable method for the study of synaptic plasticity under light microscopy. Methods Human or rat muscle specimens were fixed and sliced ​​to establish a kinetic end plate staining method by means of histochemistry. Results The staining method can simultaneously display muscle, motor end plate and motor nerve terminal structure, and quantify the germination of various nerve endings. Conclusion This article established a new neuromuscular staining method. This method saves time, simple and convenient operation, good repeatability, and provides a good method for similar research. )
