myo-inositol: a newly identified nonnitrogenous osmoregulatory molecule in mammalian brain.

Abstract:

:Sugar alcohols have been found to play an important osmoregulatory role both in unicellular organisms and, more recently, in multicellular organisms, including mammals. This study shows that myo-inositol accumulates in the brains of chronically hypernatremic mice, as had been earlier found in rats, and demonstrates for the first time a profound decrease of myo-inositol in the brains of chronically hyponatremic mice. Together with decreases in better known cerebral osmoles (amino acids and related nitrogenous compounds), the decrease in myo-inositol apparently allows the brain to balance its intracellular osmolality with that of the plasma, permitting a normal brain water content (no edema) despite profound hyponatremia.
