T4 treatment caused body silvering, an elevated plasma T4 level, and hypofunctional features both of the thyroid gland and of the pituitary TSH cells. On the other hand, TU treatment induced darker body color, hyperplasia of the thyroid gland, and hypertrophy of the pituitary TSH cells. However, neither of these treatments affected some other physiological parameters examined that are considered to be criteria characteristic of smolt status of salmonids. These results suggest that T4 controls primarily silvery transformation and that many physiological changes during smoltification are regulated by extrathyroidal factors.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"サケ·マス類のスモルト化における甲状腺ホルモンの役割を知るために,L-thyroxine(T4;餌料中 250ppm)ならびに抗甲状腺物質である,thiourea(TU;0.1%溶液に魚を浸漬)をアマゴ(On-corhynchus rhodurus)0年魚に投与し,60日間飼育した。T4処理によって,体色の銀色化が進み,血中T4濃度が増大し,甲状腺と下垂体 TSH 細胞は不活性な組織像を示した。それに対して TU処理群では,体色は暗化し,甲状腺の増生および下垂体 TSH細胞の肥大化がみられた。しかし,T4,TU 処理ともに,この他のスモルト化に特徴的な生理的変化は起こさなかった。これらの結果は,スモルト化においては,T4は体色の銀色化を促進するが, スモルト化に伴う他の多くの生理的変化は甲状腺ホルモン以外の要因によって支配されていることを示唆している。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"養殖研究所","subitem_publisher_language":"ja"}]},"item_10002_radio_30":{"attribute_name":"item_10002_radio_30","attribute_value_mlt":[{"subitem_radio_item":"吉田","subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nria_k_4_41","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":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010282450","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00245945","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0389-5858","subitem_source_identifier_type":"PISSN"}]},"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":"三輪, 理","creatorNameLang":"ja"}],"familyNames":[{"familyName":"三輪","familyNameLang":"ja"}],"givenNames":[{"givenName":"理","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"乾, 靖夫","creatorNameLang":"ja"}],"familyNames":[{"familyName":"乾","familyNameLang":"ja"}],"givenNames":[{"givenName":"靖夫","givenNameLang":"ja"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"amago; smoltification; thiourea; thyroxine","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"サイロキシンおよびチオウレアが，アマゴのスモルト化におよぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"サイロキシンおよびチオウレアが，アマゴのスモルト化におよぼす影響","subitem_title_language":"ja"},{"subitem_title":"Effects of Thyroxine and Thiourea on the Parr-smolt Transformation of Amago Salmon (Oncorhynchus rhodurus)","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955633551"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-18"},"publish_date":"2024-06-18","publish_status":"0","recid":"2007508","relation_version_is_last":true,"title":["サイロキシンおよびチオウレアが，アマゴのスモルト化におよぼす影響"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-03-27T05:57:07.833067+00:00"}
