In the present experiments, 2-cell mouse embryos were frozen under some conditions in an attempt to optimize their survival and viability in vitro. The experiments showed that embryos exposed briefly (2 to 8 minutes) to relatively high concentrations of dimethyl sulfoxide (2 to 3.5 M) and 025 M sucrose survived and developed when they were plunged directly into liquid nitrogen and thawed in a 37℃ waterbath and removed by one step dilution. DMSO was observed to be a better cryoprotectant than Propandiol (PROH) for ultrarapid freezing. Mouse preembryos were cooled in a biological freezer using 1.5 M PROH as cryoprotectant. Thawing was done at room temperature and PROH was removed by multistep dilutions. The rate of survival and development to blastocyst of zygotes by rapid, programmed freezing using PROH was 85.7% and 45.5%, and that of 2-cell stages was 76.8% and 69.8%, respectively, Similar results were achieved by ultrarapid freezing using DMSO, i. e, the rate of survival and development to blastocyst was 89.0% and 59.2% concerning zygotes and 79.1% and 64.1% concerning 2-cell stages, respectively. In conclusion, ultrarapid freezing was considered to be as effective as conventional rapid freezing, as evaluated by their subsequent development in vitro.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "127722", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Shichiri, Kazuyoshi"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟医学会"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00182415", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00290440", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "七里, 和良"}], "nameIdentifiers": [{"nameIdentifier": "127721", "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": "2019-08-16"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "106(10)_990-996.pdf", "filesize": [{"value": "1.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1400000.0, "url": {"label": "106(10)_990-996.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/20735/files/106(10)_990-996.pdf"}, "version_id": "cbae9fac-f375-49a7-b177-602a4c568a46"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Cryopreservation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "mouse preembryo", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ultrarapid freezing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Dimethyl sulfoxide (DMSO)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "凍結保存", "subitem_subject_scheme": "Other"}, {"subitem_subject": "マウス初期胚", "subitem_subject_scheme": "Other"}, {"subitem_subject": "超急速凍結法", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ジメチルスルホキシド", "subitem_subject_scheme": "Other"}]}, "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": "超急速凍結保存法を用いたマウス初期胚の生存性に関する検討", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "超急速凍結保存法を用いたマウス初期胚の生存性に関する検討"}, {"subitem_title": "超急速凍結保存法を用いたマウス初期胚の生存性に関する検討", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1169"], "permalink_uri": "http://hdl.handle.net/10191/40061", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-03-25"}, "publish_date": "2016-03-25", "publish_status": "0", "recid": "20735", "relation": {}, "relation_version_is_last": true, "title": ["超急速凍結保存法を用いたマウス初期胚の生存性に関する検討"], "weko_shared_id": null}
