Serum cortisol concentrations were measured by the high performance liquid chromatography method.<\/jats:p><jats:p> <jats:bold>\n            <jats:italic>Results<\/jats:italic>\n          <\/jats:bold>:\u2002The correlation between cortisol levels in UV and birthweight (BW) was weak and negative in premature infants. UV cortisol levels in the neonates with antenatal corticosteroid were lower than those in the neonates without antenatal corticosteroid, but the relation was not significant. The developmental changes of UV cortisol levels were the same as those in Murphy's study (spontaneous\u2010onset labor). The cortisol levels in UV and UA had a significantly positive correlation and both had almost equal concentrations. There were no correlations between cortisol levels in UV and placental weight, Apgar Score at 1 and 5\u2003min.<\/jats:p><jats:p> <jats:bold>\n            <jats:italic>Conclusions<\/jats:italic>\n          <\/jats:bold>:\u2002In the neonates whose birthweight was less than 2000\u2003g without antenatal corticosteroid, there was a negative correlation between cortisol levels in UV and BW but there was no correlation between cortisol levels in UV and GA. That the neonates with antenatal corticosteroid would have a suppressed adrenocortical function after birth could not be proved.<\/jats:p>","DOI":"10.1111\/j.1442-200x.2004.02002.x","type":"journal-article","created":{"date-parts":[[2005,2,2]],"date-time":"2005-02-02T09:46:17Z","timestamp":1107337577000},"page":"60-63","source":"Crossref","is-referenced-by-count":9,"title":["Cortisol levels in umbilical vein and umbilical artery with or without antenatal corticosteroids"],"prefix":"10.1111","volume":"47","author":[{"given":"Masahiro","family":"Manabe","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomoko","family":"Nishida","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tadashi","family":"Imai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takashi","family":"Kusaka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kou","family":"Kawada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hitoshi","family":"Okada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kensuke","family":"Okubo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenichi","family":"Isobe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susumu","family":"Itoh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,2,2]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1210\/jcem-47-3-603"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1210\/jc.78.2.266"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1203\/00006450-199501000-00021"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-119-11-199312010-00009"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1210\/jc.76.2.384"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(96)70404-3"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2002-021378"},{"key":"e_1_2_5_9_2","first-page":"193","article-title":"Spezifische Bestimmung von Corticosteron und Cortisol im Nanogramm\u2010Bereich","volume":"12","author":"Hesse C","year":"1974","journal-title":"Z.
