2) of the initial reactions caused by the foreign bodies which were plate-like flakes inserted into the subcutis, ivory was the weakest : solid silicone, cow's bone, cow's horn were a bit stronger;plastics ('FUJICON', 'DIRECT-BYOIEJIN' and 'SNUGG) were much stronger.
In the reactions caused by foreign bodies in powdered form, ivory, cow's horn, and cow's bone were the weakest, while granulated solid silicone, parafine were somewhat stronger, granulated plastics were the strogest elements.
