title: In vivo 31P NMR spectroscopy of agonist-stimulated phosphatidylinositol metabolism in cat brain.
abstract: As a result of the agonist stimulation of muscarinic receptors, myo-inositol-1-phosphate accumulates in the presence of millimolar lithium concentrations. This accumulation of myo-inositol-1-phosphate can be detected by in vivo 31P NMR spectroscopy. Since myo-inositol-1-phosphate is a breakdown product of phosphatidylinositol, this may provide a means of noninvasively monitoring phosphatidylinositol metabolism in vivo.
