Presence of podocytes at the pericardial gland suggested ultrafiltration of blood in this gland. The kidneys formed a folded duct which was divided into proximal and distal portions with different histology and cytology. In the proximal portion, the epithelium was highly infolded, and the columnar epithelial cells had a brush border, basal infoldings, and abundant mitochondria at the apical and basal cytoplasm. Furthermore, the cells had numerous invaginations of apical cytoplasmic membrane and granules, indicating reabsorption system both by active ion transport and lysosome system. In contrast, the epithelium of the distal portion was smooth and its epithelial cells were poor in basal infoldings. Analytical study demonstrated that the inorganic ions, amino acids, protein and glucose in the filtrate (primary urine) were reabsorbed by the kidneys.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"淡水産二枚貝の尿生産と浸透圧調節の機構を明らかにすることを目的とし,マルドブガイ排泄器官の電子顕微鏡観察,および血液,囲心腔液,尿の分析を行った。囲心腔腺は囲心腔壁内に発達し,足細胞(podocyte)が配列する小囊からなる。小囊は囲心腔に開孔する。腎は近位部と遠位部に分化し,両部位では上皮細胞の形態の相異が認められた。腎近位部の上皮細胞では,刷子縁,基部の折れ込み,頂部と基部に極在したミトコンドリアが観察された。さらに,この上皮細胞は頂部細胞膜の陥入と二次ラインゾーム状の顆粒を形成する吸収細胞であった。これらの結果は,血液が囲心腔腺で濾過され,次に濾液からの再吸収が腎で行われることを示唆している。血液は外界水より40mOsm高張で,尿は血液よりも6mOsm低張であること,Na+, K+, Cl-,アミノ酸,グルコースおよびタンパク質は尿から再吸収されることが分析実験によって示された。従って,マルドブガイでは,排泄系は低張な尿を生産することにより血液の高張性の維持に機能し,血液のイオン調節に関与すると考えられる。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"養殖研究所","subitem_publisher_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nria_k_10_33","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010360540","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00245945","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0389-5858","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"鈴木, 徹","creatorNameLang":"ja"}],"familyNames":[{"familyName":"鈴木","familyNameLang":"ja"}],"givenNames":[{"givenName":"徹","givenNameLang":"ja"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"bivalve; ultrastructure; pericardial gland; podocyte; kidney; osmoregulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"淡水産二枚貝，マルドブガイAnodonta (S.) calipygos，の排泄系の微細構造と生化学的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"淡水産二枚貝，マルドブガイAnodonta (S.) calipygos，の排泄系の微細構造と生化学的研究","subitem_title_language":"ja"},{"subitem_title":"Ultrastructural and Biochemical Study on the Excretory System of Freshwater Bivalve, Anodonta (S.) calipygos","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955633551"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-18"},"publish_date":"2024-06-18","publish_status":"0","recid":"2007565","relation_version_is_last":true,"title":["淡水産二枚貝，マルドブガイAnodonta (S.) calipygos，の排泄系の微細構造と生化学的研究"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-01T05:02:58.948830+00:00"}
