Abstract
Sodium-23 nuclear magnetic resonance was used to investigate the chemical functionality of sodium ion in the intact, crystalline bovine lens and vitreous humor, as compared to physiologic saline. The NMR parameters of chemical shift and T 1 and T 2 relaxation are consistent with the interpretation that the chemical functionality of sodium ion in bovine vitreous humor is identical with that of sodium ion in physiologic salt solution. Identical studies on intact bovine lens demonstrated that some fraction of the sodium ion in the lens is relatively immobilized. The calculated sodium ion interaction lifetime in the crystalline bovine lens is 3 × 10 −9 s, which is qualitatively similar to interactions described between sodium ion and the proteins troponin C and calmodulin.
