In rabbits, the percentages of oocytes showing the activities of \u03945-3\u03b2-HSD (with DHEA as the substrate), 17\u03b2-HSD (testosterone) and 20\u03b2-HSD (20\u03b2-hydroxyprogesterone) were always high and did not change during maturation, whereas those showing the activities of \u03945-3\u03b2-HSD (pregnenolone and 17\u03b1-hydroxy-pregnenolone), 17 \u03b2-HSD (estradiol-17\u03b2), 20\u03b1-HSD (20 \u03b1-hydroxyprogesterone) and 20\u03b2-HSD (17\u03b1-hydroxyprogesterone) decreased as the time after the hCG injection was prolonged. On the other hand, the activities of \u03945-3\u03b2-HSD, 17 \u03b2-HSD, 20\u03b1-HSD and 20\u03b2-HSD with eight substrates were almost always observed in hamster oocytes from 0 to 13 hrs after the hCG injection. The present findings suggested that the metabolic abilities of 20\u03b2-hydroxyprogesterone and androgen are constantly present in rabbit oocytes in the process of maturation, whereas those of progesterone, 17\u03b1-hydroxyprogesterone, 17\u03b1, 20\u03b2-dihydroxyprogesterone, 20\u03b1-hydroxyprogesterone and estrogen decrease during maturation. And it was also confirmed in hamster oocytes that the metabolic abilities of progesterone, 17\u03b1-hydroxyprogesterone, 17\u03b1, 20\u03b2-dihydroxyprogesterone, 20\u03b1-hydroxyprogesterone, 20\u03b2-hydroxyprogesterone, estrogen and androgen are always present and do not vary with maturation.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u65e5\u672c\u54fa\u4e73\u52d5\u7269\u5375\u5b50\u5b66\u4f1a"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1274/jmor.20.118", "subitem_relation_type_select": "DOI"}}]}, "item_5_relation_31": {"attribute_name": "\u7570\u7248\u3067\u3042\u308b", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://www.jstage.jst.go.jp/article/jmor/20/3/20_3_118/_pdf", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u672c\u6587\u30c7\u30fc\u30bf\u306f\u5b66\u5354\u4f1a\u306e\u8a31\u8afe\u306b\u57fa\u3065\u304dJ-Stage\u304b\u3089\u8907\u88fd\u3057\u305f\u3082\u306e\u3067\u3042\u308b"}]}, "item_5_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN10548943", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "13417738", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Niimura, Sueo"}], "nameIdentifiers": [{"nameIdentifier": "6720", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kawakami, Shin-ya"}], "nameIdentifiers": [{"nameIdentifier": "6721", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "20_3_118-123.pdf", "filesize": [{"value": "291.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 291100.0, "url": {"label": "20_3_118-123.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2037/files/20_3_118-123.pdf"}, "version_id": "c81942be-427d-4d66-a279-8ee9490520dc"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "Rabbit oocyte", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hamster oocyte", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Meiotic maturation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hydroxysteroid dehydrogenase", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Histochemistry", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Changes in the Activities of Hydroxysteroid Dehydrogenases in Rabbit and Hamster Oocytes during Meiotic Maturation", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Changes in the Activities of Hydroxysteroid Dehydrogenases in Rabbit and Hamster Oocytes during Meiotic Maturation"}, {"subitem_title": "Changes in the Activities of Hydroxysteroid Dehydrogenases in Rabbit and Hamster Oocytes during Meiotic Maturation", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["453/454", "485/486/487"], "permalink_uri": "http://hdl.handle.net/10191/25130", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2014-02-12"}, "publish_date": "2014-02-12", "publish_status": "0", "recid": "2037", "relation": {}, "relation_version_is_last": true, "title": ["Changes in the Activities of Hydroxysteroid Dehydrogenases in Rabbit and Hamster Oocytes during Meiotic Maturation"], "weko_shared_id": null}
