Abstract

A method for obtaining of biomaterials for osteoplasty and tissue engineering cleans a bone of natural origin, which is sawn to plates with a thickness of 0.2 to 2.0 cm, washed twice in 0.1 M phosphate buffer at 65° C., pH 5.8-6.0, calculated as two volumetric parts of the buffer solution per one part of bone, digested in a solution of activated 0.1-0.4% papain at 65° C. for 24 hours. The plates are washed with 5 volumes of water at the temperature 40-80° C., treated with 0.4 N alkali solution at room temperature for 10-24 hours, washed with flowing water, dried, defatted in ethanol/chloroform mixtures in proportion of 1:2 and then in proportion of 2:1, decalcified in 0.4-1 N hydrochloric acid, treated with 1.5-3% hydrogen peroxide for 4 hours, washed with treated water, then washed with ethanol, dried at room temperature, packed and sterilized.
