Cord blood levels of P1CP (the carboxy-terminal propeptide of type 1 procollagen) and 1CTP (the pyridinoline cross-linked carboxy-terminal telopeptide of type 1 collagen) were measured in 74 newborns (40 healthy newborns, 34 preterm newborns with no complications) at birth and 8 healthy infants during the first year of life. The cord blood levels of P1CP and 1CTP in the 74 newborns were 1423.5 ± 611.6 and 95.8 ± 34.2 ng/ml (mean ± SD), respectively. There were significant negative correlations between the concentra-tions of P1CP or 1CTP and gestational age, birth weight, birth length and head circumference (p<0.0001). Comparisons among the levels of P1CP and 1CTP and the rate of standard fetal weight gain, revealed the curves of P1CP and 1CTP levels to nearly parallel the curves of the standard fetal weight gain rate in male and female newborns. P1CP and ICTP levels corresponded to birth weight as well as gestational age, with the influences of other factors being negligible. We also assayed P1CP and 1CTP in 8 healthy infants under one year of age, and found that a high P1CP value and low 1CTP value resulted in a 4-fold increase in the mean P1CP/1CTP ratio, as compared to the newborns. In contrast, the P1CP/1CTP ratio was nearly constant during the preterm and term periods. The results suggest that high turnover reflects high bone remodeling activity which corresponds to rapid morphological changes in the fetal period, that high turnover processes are strongly associated with physical growth as well as gestational age in immature fetal bone and that bone formation is the dominant process in healthy infants during the first year of life.","subitem_description_type":"Abstract"}]},"item_10001_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"261044","nameIdentifierScheme":"WEKO"}],"names":[{"name":"王, 崇玫"}]},{"nameIdentifiers":[{"nameIdentifier":"261045","nameIdentifierScheme":"WEKO"}],"names":[{"name":"中野, 和俊"}]},{"nameIdentifiers":[{"nameIdentifier":"261046","nameIdentifierScheme":"WEKO"}],"names":[{"name":"白岩, 由美"}]},{"nameIdentifiers":[{"nameIdentifier":"261047","nameIdentifierScheme":"WEKO"}],"names":[{"name":"大澤, 真木子"}]},{"nameIdentifiers":[{"nameIdentifier":"261048","nameIdentifierScheme":"WEKO"}],"names":[{"name":"仁志田, 博司"}]},{"nameIdentifiers":[{"nameIdentifier":"261049","nameIdentifierScheme":"WEKO"}],"names":[{"name":"武田, 佳彦"}]}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京女子医科大学学会"}]},"item_10001_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161368","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0040-9022","subitem_source_identifier_type":"ISSN"}]},"item_10001_text_35":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Pediatrics, Tokyo Women's Medical College"},{"subitem_text_value":"Department of Pediatrics, Tokyo Women's Medical College"},{"subitem_text_value":"Department of Pediatrics, Tokyo Women's Medical College"},{"subitem_text_value":"Department of Pediatrics, Tokyo Women's Medical College"},{"subitem_text_value":"Maternal and Perinatal Center, Tokyo Women's Medical College"},{"subitem_text_value":"Maternal and Perinatal Center, Tokyo Women's Medical College"},{"subitem_text_value":"東京女子医科大学小児科学"},{"subitem_text_value":"東京女子医科大学小児科学"},{"subitem_text_value":"東京女子医科大学小児科学"},{"subitem_text_value":"東京女子医科大学小児科学"},{"subitem_text_value":"東京女子医科大学母子総合医療センター"},{"subitem_text_value":"東京女子医科大学母子総合医療センター"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-03-27"}],"displaytype":"detail","filename":"KJ00006024464.pdf","filesize":[{"value":"831.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00006024464.pdf","url":"https://twinkle.repo.nii.ac.jp/record/16934/files/KJ00006024464.pdf"},"version_id":"b9ac3f10-b92d-4444-b114-6489f507fabb"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ANALYSIS OF FETAL BONE METABOLISM EMPLOYING ASSAYS OF THE CARBOXYTERMINAL PROPEPTIDE OF TYPE1 PROCOLLAGEN AND THE PYRIDINOLINE CROSS-LINKED CARBOXYTERMINAL TELOPEPTIDE OF TYPE1 COLLAGEN","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ANALYSIS OF FETAL BONE METABOLISM EMPLOYING ASSAYS OF THE CARBOXYTERMINAL PROPEPTIDE OF TYPE1 PROCOLLAGEN AND THE PYRIDINOLINE CROSS-LINKED CARBOXYTERMINAL TELOPEPTIDE OF TYPE1 COLLAGEN"}]},"item_type_id":"10001","owner":"3","path":["1926"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-08-10"},"publish_date":"2010-08-10","publish_status":"0","recid":"16934","relation_version_is_last":true,"title":["ANALYSIS OF FETAL BONE METABOLISM EMPLOYING ASSAYS OF THE CARBOXYTERMINAL PROPEPTIDE OF TYPE1 PROCOLLAGEN AND THE PYRIDINOLINE CROSS-LINKED CARBOXYTERMINAL TELOPEPTIDE OF TYPE1 COLLAGEN"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T23:00:22.104232+00:00"}
