| Research Abstract |
Evidence of tetracycline(TC)-labelling in decalcified dentin was reported and TC uptake by a part of the organic component in calcified tissues was reconfirmed ( Simpson, 1981). This report deals with an experimental study to know possible demonstration of TC-labelling in decalcifed bone section. The results were as follows: (1) About 5 week-immersion fixation of bone tissues by 10% neutral formalin was necessary for possile demonstration of TC-labelling in decalcifed bone sections. (2) Additional fixation by cyanuric chloride after formalin fixation showed little effect for the preservation of TC-labelling in the sections. (3) Decalcification by neutral EDTA must be applied for the same purpose. (4) Degree of TC-labelling demonstrated in decalcified bone sections was varied with a type of administrated tetracycline.
