利用电子探针微区分析技术与针刺离体肌模型,研究针刺对正常肌及损伤肌细胞内Ca、Na、Mg 等离子的即刻影响,发现针后正常骨骼肌胞浆Ca 显著上升、Na 趋于下降,肌浆网Ca 含量不变。而至针后10min,损伤肌胞浆Ca 已降至正常,Na 增加3倍以上,肌浆网Ca 无明显变化。结果表明,针刺可提高正常肌膜对Ca~(2+)的通透性及损伤肌对Na~+的通透性。这种通透性的变化有可能是改变细胞膜Na-Ca 交换从而调节胞浆Ca~(2+)含量的重要机制。对针刺后即刻肌肉力量,超微结构也进行了观察。
Using electron probe microanalysis and acupuncture in vitro muscle model to study the immediate effects of acupuncture on Ca, Na and Mg ions in normal muscle and damaged muscle cells, it was found that Ca in normal skeletal muscle increased significantly after acupuncture and Na Tends to decline, sarcoplasmic reticulum Ca content unchanged. However, after 10 minutes of reperfusion, Ca (subscript Ca) in injured myocyte plasma had been reduced to normal level, while Na increased more than 3 times and Ca in sarcoplasmic reticulum did not change significantly. The results showed that acupuncture can improve the permeability of Ca ~ (2+) in normal muscular membrane and permeability of Na ~ + in damaged muscle. This change in permeability may be an important mechanism to change the Ca ~ (2+) content in the cytoplasm by changing the Na ~ Ca exchange in the cell membrane. Muscle strength immediately after acupuncture, ultrastructure was also observed.
