In this experiment, we attempted to apply μCT on morphological studies of fish pharyngeal teeth, which are difficult to investigate for their morphological characteristics, because of their complicated form and location. Goldfish pharyngeal teeth were assessed by μCT and conventional morphological techniques in order to clarify the three-dimensional fine structure of the teeth. The μCT images had high contrast and high resolution which are almost equal to those of contact microradiograph. The images clearly showed that pharyngeal teeth are directly connected to pharyngeal bone. In the reconstructed three-dimensional images of skull of goldfish, the spatial localizations of pharyngeal teeth, teethgerm and pharyngeal bone were clearly observed. In comparison with SEM method, μCT technique is non-destructive and does not require any specimen preparation. Therefore, μCT will become an effective means and bring new developments for future researches on hard tissues and comparative anatomy of various kinds of animals.","subitem_description_type":"Abstract"},{"subitem_description":"最近、骨などの硬組織微細形態を非破壊的に2次元･3次元像として観察できるμCTの応用が脚光を浴びている。そこで本研究は従来形態学的観察が困難とされてきた魚類咽頭歯に着目し、μCTを用いてキンギョ咽頭歯の立体微細形態を明らかにするとともに、従来用いられてきた組織学的方法による観察も行い、μCTの有用性を比較検討した｡その結果、contact microradiography (CMR)に匹敵する高分解能のCT像が得られ、咽頭歯が咽頭骨と骨性結合している状態が明瞭に観察された｡また3次元再構築像では、頭蓋を構成する骨が立体的に観察でき、咽頭歯およびその歯胚と咽頭骨の空間的位置関係が明瞭に観察された。走査電子顕微鏡による観察結果と比較すると、試料作製過程における構造の破壊がなくμCTが容易でかつ非破壊な手法であることが確認された｡本法を応用することによって今後各種動物等の硬組織研究、特に比較解剖学的研究に新たな展開が期待される｡","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"151970","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ishida,
