The hatching rate of blastocysts developed from morulae in a medium containing STI at a concentration of 1.0 mg/ml (STI-treated blastocysts) was 17.2%, which was significantly lower than the 63.9% for blastocysts developed from morulae in a medium without STI (non-treated blastocysts). Over the span of 32 hrs after blastocoel formation, the number of strong contractions was similar in STI-treated and nontreated blastocysts, but the total number of contractions and the number of weak contractions (less than 20% volume reduction) were significantly smaller in STI-treated blastocysts (4.22 and 2.94 times) than in non-treated blastocysts (5.80 and 4.50 times). These STI-treated blastocysts took a significantly longer time for weak contraction and for re-expansion after weak contraction (10.2 and 87.6 min), compared with non-treated blastocysts (7.8 and 58.2 min). It was also confirmed that the activity of trypsin-like proteinase was similar in STI-treated and non-treated blastocysts, and that a small hole was formed in the zona pellucida at the start of hatching in STI-treated blastocysts, as seen in non-treated blastocysts. Nevertheless, the rate of blastocysts with a slit resulting from enlargement of the small hole in the zona pellucida was 37.5% in STI-treated blastocysts, which was significantly lower than the 86.7% in non-treated blastocysts. These results suggest that weak contraction and re-expansion after weak contraction of blastocysts play an important role in hatching by slitting the region adjacent to the small hole in the zona pellucida.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"6730","nameIdentifierScheme":"WEKO"}],"names":[{"name":"新村, 末雄","nameLang":"ja"}]},{"nameIdentifiers":[{"nameIdentifier":"6731","nameIdentifierScheme":"WEKO"}],"names":[{"name":"若狭, 良子","nameLang":"ja"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japanese Society of Mammalian Ova Research","subitem_publisher_language":"en"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1274/jmor.18.1","subitem_relation_type_select":"DOI"}}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12018687","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1341-7738","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Niimura, Sueo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"6728","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wakasa, Ryoko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"6729","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"2009030024.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2009030024.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2040/files/2009030024.pdf"},"version_id":"d16a7074-6eb9-451b-afcc-e98c9be9b575"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Mouse","subitem_subject_scheme":"Other"},{"subitem_subject":"Blastocyst hatching","subitem_subject_scheme":"Other"},{"subitem_subject":"Contraction","subitem_subject_scheme":"Other"},{"subitem_subject":"Soybean trypsin inhibitor","subitem_subject_scheme":"Other"},{"subitem_subject":"Time-lapse videomicrography","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Contractions of Mouse Blastocysts Whose Hatching Abilities were Suppressed by Soybean Trypsin Inhibitor","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Contractions of Mouse Blastocysts Whose Hatching Abilities were Suppressed by Soybean Trypsin Inhibitor","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","487"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-04-09"},"publish_date":"2009-04-09","publish_status":"0","recid":"2040","relation_version_is_last":true,"title":["Contractions of Mouse Blastocysts Whose Hatching Abilities were Suppressed by Soybean Trypsin Inhibitor"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-15T03:34:54.823602+00:00"}
