| Abstract: | The monolayer cultures of newborn rats hepatocytes were treated with substrate starvation (20 min.) anoxia accompanied with substrate starvation (1 h.), following rehabilitation (1 h.) and cooling (4 degrees C, 30 min). After the neutral red staining we have examined the alterations in lysosomes quantity and the development of phagocytosis; we also tested the hepatocytes distribution due to the amount of the second lysosomes per cell. We have shown that a short time pathological treatment caused a decrease in large lysosomes (1-3 microns) amount in significant portion of hepatocytes. There were neither increase in phagosomes amount per cell nor alterations in the quantity of cells, containing phagosomes. However a long time pathological treatment caused the increase in phagosomes and cells. We propose that initial stage of lysosomal apparatus alterations, connected with reduction of CAMP level, is accompanied by a stamping of large lysosomes. |
