Abstract
The comparison was made between the reaktions caused by various types of foreign bodies placed into the subcutaneous tissue of rabbits through a small window in the skin.
1) The window was made of glass, and it was found to be less lrritable and more suitable to it. Next in order of suitability celluliod, and then plyvinyl chlorid, acethyloid and the other platsics which the author used were comparatively irritable.
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.
