[Dynamic glycogen synthesis in the hepatocytes of different areas of the hepatic lobes in rats].
Using image analyser Magiscan, a quantitative analysis of the total glycogen and of its two fractions was made in hepatocytes of portal and central zones of the liver lobule of rats after a 48 hour starvation and 15, 30, 60, 120 minutes after refeeding. Glycogen content was the lowest after a 48 hour starvation and only a few cells of the central zone contained a noticeable glycogen quantity. Glycogen synthesis initiation began 15 minutes after refeeding. Glycogen synthesis is characterized by a higher glycogen content in the portal zone of liver lobule, and further this difference was even more increased. Different changes were observed in the content of glycogen fractions in the process of glycogen resynthesis after starvation of rats.
