Abstract

Remodeling of the extracellular matrix of the liver in mice with BCG-induced granulomatosis after 2-month course of intraperitoneal injections of isonicotinic acid hydrazide, oxidized dextran conjugated with isonicotinic acid hydrazide, dextrazide, and its liposome-encapsulated form manifested in modification of the proteoglycan composition and hydroxyproline fractions associated with changes in hyaluronidase and MMP activities. The antifibrotic effect of dextrazide and its liposome-encapsulated form manifested in reduction of hydroxyproline fractions that reflected the process of collagen synthesis. Administration of isonicotinic acid hydrazide was followed by a decrease in hydroxyproline fractions reflecting collagen synthesis (antifibrotics effect) and degradation (profibrotic effect), which can be explained by its hepatotoxic activity.
