The concentrations of total glycogen (TG) and its labile (LF) and stable (SF) fractions were determined in hepatocytes of portal and central zones of the normal human liver and in the liver of patients with cirrhosis of viral and alcohol aetiologies. Using PAS reaction, TG, LF and SF were revealed in histological sections of the material obtained by the liver punch biopsies. The concentrations of TG and its fractions were measured by televisional cytophotometry. In liver cirrhosis, the concentrations of TG, LF and SF in both zones of the hepatic lobule have been found to be much higher than in the normal liver. It has been shown that the ratio of the hepatocyte TG concentrations in the portal zone to the central zone both in the normal liver and in viral cirrhosis exceeds 1.0, amounting to 1.264 +/- 0.021 and 1.030 +/- 0.009, respectively. The glycogen fraction composition in the cells of both the liver lobule zones in viral cirrhosis does not differ significantly from the norm. On the contrary, in the liver of patients with alcoholic cirrhosis, the ratio of the TG concentrations in the portal zone to the central zone is reduced to 0.815 +/- 0.016 and is accompanied by qualitative changes of the glycogen composition.
