    Abstract:
    Concentration of glycogen and activity of enzymes, participating in its metabolism, were studied in punctates of liver tissue obtained from three patients with clinical manifestations of hepatic forms of glycogenosis. Accumulation of glycogen in liver tissue of the patients was caused by distinct decrease in the phosphorylase activity. In two patients low activity of phosphorylase A was due to impairment of one of the enzymes, activating the phosphorylase in liver tissue, and in one patient phosphorylase B itself exhibited low activity. The in vitro data on glycogen metabolism were correlated with those, obtained in study of glycogen turnover in vivo, after loading with adrenaline. The data obtained enable to develop methods for treatment of the patients with impairments in activity of liver phosphorylase.
