Subcellular distribution of hyaluronidase of rat liver was studied during spontaneous restoration during the 1st, 2nd, 3rd days, and 1, 2, 3, 4 weeks of acute and chronic CCl4-hepatitis. Redistribution of relative specific activity of hyaluronidase was seen in the fractions of heavy and light mitochondria, microsomes and supernatant fraction, after an acute hepatic injury. Four weeks after the injury subcellular distribution was not yet normal. In chronic hepatitis the relative specific hyaluronidase activity was almost identical in the five subcellular fractions. In the course of restoration the relative specific activity was increased in the fractions of heavy and light mitochondria and microsomes, but decreased in the nuclear and supernatant fractions.

The extractable and nonextractable collagen and glycosaminoglycuronans (GAG) were estimated and characterized in 32 dried, defatted human livers obtained at necropsy. 10 had normal livers. 22 of the 32 livers were from patients who drank in excess: 5 had fatty livers, 7 had alcholic hepatitis, and 10 had cirrhosis. Livers with alcoholic hepatitis or cirrhosis had significantly increased total and 1 N NaCl-extractable collagen. Only alcoholic hepatitis livers had significantly increased Tris-buffer-extractable GAG, but the amino acid composition of these GAG (proteoglycans) was no different from that of normal livers. The major fraction of these GAG had isoelectric pH (pI) </= 3.1 in all livers. Livers with alcoholic hepatitis or cirrhosis had significantly increased nonextractable GAG. The major GAG fraction of all livers was chondroitin-4 or -6-SO(4). Alcoholic hepatitis livers had a significant increase of hyaluronic acid and an unidentified hyaluronidase-resistant GAG. Fatty livers showed no differences from normal ones. The data indicates that alcoholic hepatitis is associated with a significantly increased fibroblast activity, but fatty livers of alcoholics are not. The changes in histologically "inactive" micronodular cirrhosis of alcoholic patients indicate continued activity of fibroblasts in the connective tissue of these cirrhotic livers.

Immobilized hyaluronidase (nanotechnology method of electron-beam synthesis) exhibited high hepatoprotective activity on the model of Cl4-induced hepatitis. This agent produced anticholestatic, anti-inflammatory, and antisclerotic effects. These effects were shown to accompany stimulation of multipotent bone marrow precursors, mobilization of these cells into the peripheral blood, and cell migration to the target organ increasing the number of parenchymal progenitor cells in the liver. The mechanisms for targeted migration of progenitor cells suggest a decrease in SDF-1 production by bone marrow stromal cells and increase in the synthesis of this factor by microenvironmental cells of the liver tissue.

High hepatoprotective activity of granulocytic CSF and hyaluronidase immobilized using electron-beam immobilization technology was demonstrated on the model of CCl(4)-induced hepatitis: the preparations produced anticholestatic, anti-inflammatory, and antisclerotic effects. These effects developed against the background of stimulation of bone marrow multipotent precursor cells and their mobilization into circulation accompanied by an increase in the content of parenchymatous progenitor cells in the liver. The most pronounced positive effect was observed in combined treatment with the test preparations.
