We previously found a marked decrease of GRP-immunoreactivity from nerve fibers in the oxyntic mucosa with stress-induced ulcers. The unusual release of GRP from the nerves under stress conditions seems to cause acute mucosal erosions. Since GRP has an action of vasoconstriction which may be responsible for the genesis of ulcers, the present study focuses on the relationship of GRP nerves and blood vessels. The GRP-immunopositive nerves were found to run close to the blood vessels throughout the mucosa. Scanning and transmission electron microscope observations showed that the nerve bundles containing GRP fibers were topographically associated with capillaries, but not with any glandular cells. The oxyntic mucosa is supplied exclusively by capillaries without smooth muscles which may respond to GRP. However, the capillaries here were accompanied by pericytes which reportedly are contractile in nature. Pericytes were frequently found intervening between the capillaries and nerves. The present finding suggests a possibility that GRP released from nerves reduces mucosal blood flow via the contraction of pericytes, finally causing mucosal ischemia and damage.", "subitem_description_type": "Abstract"}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Niigata University School of Medicine"}]}, "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": "AA00508361", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "05677734", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Iwanaga, T."}], "nameIdentifiers": [{"nameIdentifier": "53828", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Takahashi-Iwanaga, H."}], "nameIdentifiers": [{"nameIdentifier": "53829", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Fujita, T."}], "nameIdentifiers": [{"nameIdentifier": "53830", "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": "2019-08-06"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "37(1)_35-43.pdf", "filesize": [{"value": "4.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 4300000.0, "url": {"label": "37(1)_35-43.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/6654/files/37(1)_35-43.pdf"}, "version_id": "1c6559fa-8212-46c0-a1ab-25c0540dd752"}]}, "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": "Possible Mechanism of GRP (Gastrin-Releasing Peptide)-Containing Nerves Regulating the Mucosal Microcirculation in the Rat Gastric Body", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Possible Mechanism of GRP (Gastrin-Releasing Peptide)-Containing Nerves Regulating the Mucosal Microcirculation in the Rat Gastric Body"}, {"subitem_title": "Possible Mechanism of GRP (Gastrin-Releasing Peptide)-Containing Nerves Regulating the Mucosal Microcirculation in the Rat Gastric Body", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "650"], "permalink_uri": "http://hdl.handle.net/10191/33535", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-10-06"}, "publish_date": "2015-10-06", "publish_status": "0", "recid": "6654", "relation": {}, "relation_version_is_last": true, "title": ["Possible Mechanism of GRP (Gastrin-Releasing Peptide)-Containing Nerves Regulating the Mucosal Microcirculation in the Rat Gastric Body"], "weko_shared_id": null}
