Out of 209 strains of fungi which showed strong acute toxicity on mice in the previous short-term experiments, 12 strains of Aspergillus (Asp.) and two strains of Penicillium (Pen.) were selected for the study. Two strains of Asp. flavus; GN-22-1-5 and GN-25-1, Asp. oryzae GN-21-2-4 and Asp. candidus SM-10-2 caused atrophy of the liver. However, no obvious fibrosis, cirrhosis or other chronic lesions of the liver were observed. Asp. flavus BE-13-4 was the only strain that caused marked pleomorphism of the liver cell nuclei. A few strains of Aspergillus and Pen. funiculosum GN-48-8 caused swelling and nuclear pleomorphism of proximal tubules of the kidney. Marked hypospermatogenesis of the testis was seen in mice treated with Pen. funiculosum GN-48-8. The methods for administraion of fungal culture filtrates were discussed.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"熱帯医学 Tropical medicine 22(2). p95-100, 1980","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"104914","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Itakura, Hideyo"}]},{"nameIdentifiers":[{"nameIdentifier":"104915","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamashita, Hiroto"}]},{"nameIdentifiers":[{"nameIdentifier":"104916","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kawasaki, Yosuke"}]},{"nameIdentifiers":[{"nameIdentifier":"104917","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Mizunuma, Takeji"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学熱帯医学研究所"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00199644","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03855643","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"P00095-P00100"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Institute of Tropical Medicine, Nagasaki University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"板倉, 英世"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山下, 裕人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川崎, 洋介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"水沼, 武二"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-24"}],"displaytype":"detail","filename":"tm22_02_03_t.pdf","filesize":[{"value":"423.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tm22_02_03_t.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/24905/files/tm22_02_03_t.pdf"},"version_id":"146d545c-d916-4fdd-baba-4866b1c6cf44"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"東アフリカ・ウガンダ国の主要食品類より分離された毒性真菌類 : 真菌培養濾液の慢性毒性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東アフリカ・ウガンダ国の主要食品類より分離された毒性真菌類 : 真菌培養濾液の慢性毒性"}]},"item_type_id":"3","owner":"2","path":["1828"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-04-26"},"publish_date":"2006-04-26","publish_status":"0","recid":"24905","relation_version_is_last":true,"title":["東アフリカ・ウガンダ国の主要食品類より分離された毒性真菌類 : 真菌培養濾液の慢性毒性"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T23:58:17.169322+00:00"}
