  • Title: Effect of the activation of macrophages on the course of regeneration of rat liver following partial hepatectomy.

    Journal: Physiol Bohemoslov; 1986; 35(5):473-80. PubMed ID: 2948209.
    Abstract:
    Stimulation of the Kupffer cells with E. coli endotoxin (the purified lipopolysaccharide) or with prodigiosan (a polysaccharide from Serratia marcescens) 24 h before partial hepatectomy (resection of 65-70% of the liver) stimulated and intensified the onset of liver regenerative activity (evaluated from changes in liver DNA synthesis, the H5 labelling index and the mitotic activity of the hepatocytes). Liver DNA synthesis increased together with the dose of endotoxin (i.v., from 25 to 1000 micrograms/kg body weight). If E. coli endotoxin was injected during or 3 h after partial hepatectomy, partial inhibition of liver DNA synthesis was observed. In mice stimulated with zymosan (a polysaccharide isolated from yeast), administered 5 days before performing partial hepatectomy, proliferation of the hepatocytes (evaluated from changes in the 3H labelling index and in the mitotic activity of the hepatocytes) was evaluated. The results confirm that proliferation is correlated to the state of reactivity of the Kupffer cells.
