BIOLOGICAL MATERIAL ALLOPLANT USABLE IN RECONSTRUCTIVE SURGERY Russian patent published in 2002 - IPC

FIELD: medicine. SUBSTANCE: material is connective tissue taken from donor that is selected to have 70% correspondence fibrous structure of tissue to be substituted and chemical bounds of proteoglycanes and glycoproteins structured in collagen fibers are by 80-90% released in fibrous components of donor connective tissue. Glycosamines are partially eliminated from fiber fascicles to achieve residual contents of greater than or equal to 50%. Donor tissue distinguished by predominating contents of gyaluronic acid in extracellular matrix is used in the biological material for repairing dense connective tissue. Donor tissue distinguished by low contents of gyaluronic acid in extracellular matrix is used in the biological material for repairing loose connective tissue. Donor tissue distinguished by predominating contents of heparan sulfate is used in the biological material for repairing epithelial tissue. Donor tissue distinguished by predominating contents of chondroitin sulfate is used in the biological material for forming regenerate reach in blood vessels. Dispersed form crushed to powder condition is applied for repairing fibrous and degenerative dystrophic changes in tissues. Complex anatomical defects are repaired with combined donor tissues differing in proportions and geometric shapes. EFFECT: enhanced effectiveness of treatment; production of non-toxic transplants. 7 cl, 1 tbl
