An examination of graft alteration and recipient response to processed mare cortical bone xenografting.

fe]lows. 1) By roentgenographie examination, the bone graft density was increasecl quickly in order of deproteinized, frezen, boiled, and fresh graft. 2) By gro$s appearance, the ossal fusion between the graft and the recipient was completed in all deproteinized and frozen grafts and in a few boiled and fresh graft. 3) The bone replacement in graft was not found up to 16 weeks after implantation in all the processed and fresh grafts. 4} The maior bone mineral contents at the end of 16 weeks after implantation were nenrly in agreement with the absorption rate {n each graft. 5) There were no changes on blood cells and serurn electrophoretic fractions of reeipients implanted with non-processed fresh graft.
