Estradiol-17β was maintained at constant levels (5 ng/ml) during the experimental period (from 0h to 24 h after HCG injection). Testosterone levels gradually increased after treatment and reached a peak at 3 h followed by a significant decrease at 12 h. Mean levels of all progestational steroids measured (progesterone, 17α-OHprog, 17α, 20β-diOHprog) increased following treatment and reached a peak at 6h, at which time 2 out of 6 fish contained matured oocytes and the remainder had oocytes of the migratory nucleus stage. There were significant differences in the levels of these steroids between the two groups, the levels being much higher in females which underwent final maturation. The greatest elevation was observed in the level of 17α, 20β-diOHprog at 6 h, which was more than 30 times that at 0h. The levels of progestational steroids rapidly decreased at 12 h, followed by a further decrease at 24 h. In this experiment, all fish ovulated by 12 h following injection. These results are discussed in relation to other studies on changes in plasma steroid levels during final oocyte maturation and ovulation.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"ヒト胎盤性性腺刺激ホルモン(HCG)を投与すると同時に水温を上昇させて最終成熟·排卵を誘起したキンギョの血中 estradiol-17β (E2), testosterone (T), progesterone (P), 17α-hydroxyprogesterone (17α-OHprog),および17α, 20β-dihydroxy-4-pregnen-3-one(17α,20β-diOHprog)量の変化をラジオイムノアッセイ法により測定した。その結果,E2は実験期間中(0時間-24時間)変化することなく一定の値(5ng/ml)を保った。T量は3時間目まで徐々に上昇し(10-15ng/ml),12時間目で減少した(5ng/ml)。測定した3種のプロゲステロン系ステロイドは同様の変化を示し,注射後6時間目に最高値に達した。特に,17α, 20β-diOHprog は実験開始時と比べて30倍も増加した。この時,6尾中2尾が成熟卵を有し,残りは核移動期にあり,これら3種のステロイド量は成熟卵を有していた魚のほうが核移動期のものよりも高い値を示した。その後,これら3種のプロゲステロン系ステロイドは12-24時間にかけて急激に減少した。実験に用いた魚は注射後12時間目までにすべて排卵した。","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_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nria_k_17_17","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/2010461293","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":"桧垣, 浩彦","creatorNameLang":"ja"}],"familyNames":[{"familyName":"桧垣","familyNameLang":"ja"}],"givenNames":[{"givenName":"浩彦","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"長浜, 嘉孝","creatorNameLang":"ja"}],"familyNames":[{"familyName":"長浜","familyNameLang":"ja"}],"givenNames":[{"givenName":"嘉孝","givenNameLang":"ja"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"goldfish; human chorionic gonadotropin injection; oocyte maturation; ovulation; plasma steroids","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"胎盤性性腺刺激ホルモンにより誘起されたキンギョ，Carassius auratus，の卵成熟・排卵時における血中ステロイドホルモン量の変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"胎盤性性腺刺激ホルモンにより誘起されたキンギョ，Carassius auratus，の卵成熟・排卵時における血中ステロイドホルモン量の変化","subitem_title_language":"ja"},{"subitem_title":"Changes in Plasma Steroid Levels in the Goldfish, Carassius auratus, During Final Oocyte Maturation and Ovulation Induced by a Combination of Human Chorionic Gonadotropin and Elevated Holding Temperature","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":"2007608","relation_version_is_last":true,"title":["胎盤性性腺刺激ホルモンにより誘起されたキンギョ，Carassius auratus，の卵成熟・排卵時における血中ステロイドホルモン量の変化"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-02T08:05:36.677636+00:00"}
