The scientific research activity is focused on assessment of the extracellular matrix components metabolism and free radical and antioxidant activity during physiological conditions and selected pathologies, including connective tissue diseases, diabetes type 2, obesity, and inflammatory bowel diseases. The scientific research activity is focused on the analyses of glycosaminoglycans structure and content, as well as extracellular matrix proteins during tissue repair process in experimental burn wounds healing and the implementation of the pluripotent natural raw material, for the improvement of the efficiency of extracellular matrix remodeling, in the course of experimental burn wounds healing. Additional research is related with the assement of the role of adipocytokines in the development of the obesity and type 2 diabetes mellitus.
