title: [Study of human muscle biopsies with muscle glycogen storage diseases using 1H nuclear magnetic resonance spectroscopy (NMRS)--analysis of perchloric acid extracts of muscles].
abstract: Muscle metabolites of perchloric acid extracts in human muscle biopsies including the cases with muscle glycogen storage diseases (GSD) were analyzed using 1H NMR spectroscopy. Several metabolites such as lactate, pyruvate, creatine, phosphocreatine, acetate, alanine, carnitine and glycogen were recognized. The cases with GSD III and GSD V showed two broad signals at 3.60 and 3.85 ppm which were considered to be the proton signals from the accumulated glycogen. However, in GSD III, the signal at 3.60 ppm was high compared with that at 3.85 ppm suggesting that glycogen was increased in its degree of branching joined by alpha-1,6 linkage. These data suggest that 1H NMR spectroscopy is a useful and simple technique for analysis of muscle glycogen storage diseases as well as lipid myopathies.
