title: Analysis of sodium-23 nuclear magnetic resonance spin-lattice relaxation for the study of the intracellular sodium state.
abstract: Sodium-23 Nuclear Magnetic Resonance relaxation spectroscopy has been used to investigate the state of intracellular Na+ in control and CCl4-treated rat livers. The analysis of spin-lattice relaxation rates at 1.88 and 7.07 Tesla based on a two-site exchange model led to estimates of pertinent modulation times. Also it has been found that a relatively high quantity of Na+ (PB = 1.59 x 10(-2)) is bound to charged sites of intracellular macromolecules or membranes. The degree of binding strongly decreases in CCl4 treated rat livers.
