And the mammary gland at a brief period in a sexual cycle of fin whales was collected, as the whaling season is very short. 3) From the histological viewpoint of the mammary gland of fin whales in this season in the Eastern Sea, the females show the following eight stages of maturity. (1) Immature whales There is no corpus luteum and corpus albicans in ovary. The colour of mammary gland is white or light pink and it is 2mm. -3cm. thick. The greater part of the range of vision in histological low power is occupied by the interlobular connective tissue and the little immature lobules are found here and there. In high power the alveolo-tubular end piece closes in the mass of epithelium or alveoli. (2) Whales which experienced ovulation but not pregnancy The mammary gland has equal histological contents to those of immature whales but there is a corpus albicans in ovary, and it is supposed that the whale arrives at the biological minimum and that corpus albicans was grown by ovulation but not by pregnancy. The colour and thickness of mammary gland is equal to those of the immature whales, too. (3) Whales in their first pregnancy As the foetus has been flowed out, the accurate pregnant period can not be concluded from its body length, but judging from the length and diameter of uterine cornu and the season of the catch, it is supposed that the whale goes past the middle stage of pregnancy. By the histological observation of the mammary gland the whale in this stage is equal to the immature whale and itis guessed that the mammary gland in whales is not developed at the first and middle stages , bu tdeveloped rapidly at the last stage of pregnancy and it is different from the case of human being s.The colour and thickness of mammary gland is equal to those of the immature whale .(4) Lactating whalesThese are t h e whales whose milk dropped out from the mammary gland at the dissection. By thehistological observation in low power, the mammary gland consists mainly of the increased lobu l esand the interlobular connective tissue is pressed and appears to be a line . In high powe r , theexcretory duct, lactiferous duct and the lumen of the alveolo-tubular end piece hold a great quant i tyof oil drops and the secreting epithelium is in an active state. The mammary gland is about 30cm.thick in the height of lactation and 15cm. - 20cm. in the last stage.(5) Thh first stage in the weaning periodIn high power the lumens are w i d e open and there is no oil drop in them and all the cells ofthe secreting epithelium make a present of inactive state. In this case the mammary gland is 10cm . -12cm. thick.(6) The last stage in the weaning periodThe mammary gland is 7cm. -10 c m. thick. By the histological observation the lobules are shrunkto some extent on the whole, that is, in low power the interlobular connective tissue is inc reasedin breadth and in high power the alveolo-tubular end piece is not fully shrunk yet, but it can bedistinguished from the end piece of the resting whale.(7) Resting whalesThese are the whales whose have experienced no pregnancy, parturition and lactation during theyear. The mammary gland is 4cm.-5cm. thick, its colour being yellow. In low power by t hehistological observation, the interlobular connective tissue is much increased and the lobules are divid edinto many blocks by it, in high power the alveolo-tubular end piece indicates the stable an d fullyshrunk condition, but it is different from the end piece of the immature whale.(8) Whales experiencing pregnancy more than twiceFrom the histological viewpoint, thickness a nd colour of the mammary gland are equal to thoseof the resting whales. It is confirmed again by this evidence that the mammary gland in whal es isdeveloped rapidly at the last stage of pregnancy.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学水産学部研究報告, v.7, pp.11-20; 1959","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"29867","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Mizue, Kazuhiro"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学水産学部"}]},"item_3_relation_29":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40018181191","subitem_relation_type_select":"NAID"}}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178473","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05471427","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"水江, 一弘"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"suisan07_011.pdf","filesize":[{"value":"5.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"suisan07_011.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/7053/files/suisan07_011.pdf"},"version_id":"4783ee22-d03e-4b3e-adad-c97c07597248"}]},"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":"Balaenoptera spp.の乳腺及び卵巣についての組織学的研究―1 : 東海産長須鯨の乳腺について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Balaenoptera spp.の乳腺及び卵巣についての組織学的研究―1 : 東海産長須鯨の乳腺について"}]},"item_type_id":"3","owner":"2","path":["497"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-05-21"},"publish_date":"2013-05-21","publish_status":"0","recid":"7053","relation_version_is_last":true,"title":["Balaenoptera spp.の乳腺及び卵巣についての組織学的研究―1 : 東海産長須鯨の乳腺について"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T02:32:58.788534+00:00"}
