Abstract

Muscle, spleen, and kidney tissues from 4-wk-old C57 black mice were studied by proton magnetic resonance. Spin-lattice relaxation times at high fields and in the rotating frame, as well as the spin-spin relaxation times, are reported as a function of temperature in the liquid and frozen phase. Motions of large molecules and of water molecules and their changes at the freezing phase transition are studied. The shortcomings of the two-state fast-exchange relaxation model are discussed.

摘要

对4周龄C57黑小鼠的肌肉、脾脏和肾脏组织进行了质子磁共振研究。报告了高场和旋转坐标系下的自旋晶格弛豫时间以及自旋-自旋弛豫时间与液相和冷冻相温度的函数关系。研究了大分子和水分子的运动及其在冷冻相变时的变化。讨论了双态快速交换弛豫模型的缺点。
