Abstract
It is shown that roughly 4 mmol carbon atoms/g mouse muscle can give rise to a "high resolution" 13C NMR spectrum. From the 13C spectrum, it is estimated that the protons from mobile organic molecules or molecular segments amount to 6-8%of total nonrigid protons (organic plus water) in muscle. Their spin-spin relaxation times (T2) are of the order of 0.4-2 ms. At 37 degrees C, the proton spin-echo decay of mouse muscle changes rapidly with time after death, while that of mouse brain does not.
摘要
结果表明，每克小鼠肌肉中约4毫摩尔碳原子可产生“高分辨率”的13C核磁共振谱。从13C谱估计，来自可移动有机分子或分子片段的质子占肌肉中总非刚性质子（有机质子加水质子）的6 - 8%。它们的自旋 - 自旋弛豫时间（T2）约为0.4 - 2毫秒。在37摄氏度时，小鼠肌肉的质子自旋回波衰减在死后随时间迅速变化，而小鼠脑的质子自旋回波衰减则不然。
