[A biological compatibility study of hydroxyapatite]

The biological compatibility of coatings of subcutaneous implants was studied in rat experiments. The implants were coated with hydroxyapatite and hydroxyapatite modified by chloromethylsilanthrane (silamine). The coatings were found to inhibit lipid peroxidation and form the optimal ratio of connective tissue biopolymers in capsules forming round the implants. Both types of hydroxyapatites used were characterized by high biological compatibility.
