Preliminary studies on the potential of in vivo deuterium NMR spectroscopy.

Natural abundance deuterium NMR spectroscopy can be used to characterise in vivo 2H signals arising from water and fat in mice, with acquisition times of less than two minutes. Administration of D(2)0 (10% V/V) in the drinking water enhances these signals so that excellent spectra can be obtained with one scan. Using these procedures the in vivo turnover of 2H in water and fat in mice has been determined. This procedure may be of particular importance in studies of fat turnover in obesity.
