In a primary infection, male mice showed greater susceptibility than did females as defined by counting the number of worms recovered from the peritoneal cavity. Sex difference appeared at the early phase of primary infection (5-10 days) and continued for at least 7 weeks of infection. Inoculation with the 3rd stage larvae was effective in inducing sex difference, whereas inoculation with the 4th stage larvae had no effect. Therefore, sex difference in susceptibility seems to be induced by the 3rd stage larvae (possibly molting stage larvae). Since sex difference was only observed in a primary infection but not in a challenge infection, the expression of sex difference might be dependent upon some differences of development of early phase of immune response to the larval worm of B. pahangi between the sex. Thus, in the present study, the difference in immunological response of host to filarial worm was examined. Significantly great number of effector cell infiltrations (macrophages and eosinophils were predominant) were observed in the peritoneal cavities of female mice 10 days after infection. Whereas no significant difference in the levels of anti-B. pahangi IgG, IgM and IgE were observed at this time of infection, the cellular reaction that occured in female mice 10 days postinfection may be one of the factors which reflects the differential sex susceptibility of host in B. pahangi-mouse model.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"熱帯医学 Tropical medicine 29(3). p153-163, 1987","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"106652","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakanishi, Hirokum"}]}]},"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":"P00153-P00163"}]},"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":"中西, 弘有"}],"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":"tm29_03_03_t.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tm29_03_03_t.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/25126/files/tm29_03_03_t.pdf"},"version_id":"83ea8ae1-956b-44b0-8bed-e7cfe558cc5d"}]},"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":"BALB/cマウスにおけるBrugia pahangi感染感受性の性差 : エフェクター細胞の反応の性差について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"BALB/cマウスにおけるBrugia pahangi感染感受性の性差 : エフェクター細胞の反応の性差について"}]},"item_type_id":"3","owner":"2","path":["1858"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-04-26"},"publish_date":"2006-04-26","publish_status":"0","recid":"25126","relation_version_is_last":true,"title":["BALB/cマウスにおけるBrugia pahangi感染感受性の性差 : エフェクター細胞の反応の性差について"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T23:49:03.895738+00:00"}
