琥珀酸脱氢酶-乙酰胆碱脂酶结合显示法对肌梭的形态学研究

The morphological research on combined enzymatic reaction for muscle spindles

通过SDH-AchE酶结合方法,对人蚓状肌肌梭进行了观察,结果显示肌梭内肌纤维呈蓝色,肌纤维显著较梭外肌纤维细,并在其上可见有运动终板分布。此结果使在同一切片对肌肉、运动终板、肌梭进行定性、定量分析研究成为可能,为研究神经肌肉病变提供了较好的方法。

The muscle spindles in human lumbrical were observed with the combined enzymatic reaction technique (succinate dehydrogenase and acetyl-cholinesterase). The intrafusal muscle fibers rendered blue color. and were significantly smaller than extrafusal muscle fibers. Our study made it possible to conduct quantitative and qualitative analysis of muscle, motor-end-plates and muscle spindles on the same frozen section.
