Pearl oysters in which the pearl nucleus had been inserted were injected with 2mg of tetracycline HCI (achromycin) dissolved in 0,1ml of sea water at each time. Tetracycline is selectively incorporated into newly formed nacre and can be identified by the fluorescence. After sampling of the shells and pearls, they were sectioned by grinding, and examined with the aid of a compound microscope in both visible and ultraviolet light. They were illustrated in pearls, figs. 1A, and 3A, and in shells, figs. 3-5. Note four brilliant fluorescent bands in each photograph, indicative of the four injections of tetracycline administered. Figs. 1B, 2B and 3B also show the photograph of the same section taken with visible light. By means of this method, the author measured the growth rate of the nacreous layer of shells and pearls in each season.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立真珠研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National Pearl Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"pearl_k_607","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本真珠振興会Archive"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://jp-pearl.com/wp-content/uploads/2018/04/houkoku00601.pdf#009","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00091717","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakahara, Hiroshi","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"中原, 晧","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"ナカハラ, ヒロシ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Nakahara","familyNameLang":"en"},{"familyName":"中原","familyNameLang":"ja"},{"familyName":"ナカハラ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Hiroshi","givenNameLang":"en"},{"givenName":"晧","givenNameLang":"ja"},{"givenName":"ヒロシ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3283","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"テトラサイクリンの使用による真珠層の生長度の測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"テトラサイクリンの使用による真珠層の生長度の測定","subitem_title_language":"ja"},{"subitem_title":"Determination of growth rates of nacreous layer by the administration of tetracycline","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955633551"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-27"},"publish_date":"2024-06-27","publish_status":"0","recid":"2008984","relation_version_is_last":true,"title":["テトラサイクリンの使用による真珠層の生長度の測定"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-13T02:41:29.056912+00:00"}
