The clinical value of this method was evaluated in this study with abnormal pregnancies, twin pregnancies, and pregnancies associated with fetal anencephaly or complicated by gestational toxicosis or diabetes mellitus. A significant correlation was demonstrated between an abrupt decrease in serum u\u2010E<jats:sub>3<\/jats:sub> level and an abnormal pattern on fetal heart rate monitor. Since urinary E<jats:sub>3<\/jats:sub> was not sensitive enough to detect any depressed fetal condition, serum u\u2010E<jats:sub>3<\/jats:sub> is better biochemical parameter for assessment of fetal well\u2010being.<\/jats:p><jats:p>In addition, u\u2010E<jats:sub>2<\/jats:sub> was measured in the sera of nonpregnant women with separation chromatography as a pretreatment in order to obtain higher sensitivity of the system. This modified HPLC system enabled us to determine the serum u\u2010E<jats:sub>2<\/jats:sub> in about 60 min with the minimal detectable value of 80 pg\/ml; the coefficient of correlation with RIA was 0.822. As a result, this quick measurement of u\u2010E<jats:sub>3<\/jats:sub> and u\u2010E<jats:sub>2<\/jats:sub> by our HPLC system revealed to be useful not only for evaluating fetoplacental function but also for monitoring ovarian follicle maturation.<\/jats:p>","DOI":"10.1002\/jcla.1860060102","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T20:26:17Z","timestamp":1173126377000},"page":"1-6","source":"Crossref","is-referenced-by-count":2,"title":["Quick measurement of serum unconjugated estrogens, and its clinical application to abnormal pregnancies and ovarian follicle maturation"],"prefix":"10.1002","volume":"6","author":[{"given":"Zenjiro","family":"Kondo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsunehisa","family":"Makino","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shun\u2010Ichiro","family":"Lzumi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rihachi","family":"Lizuka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,10,20]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/jcla.1860040604"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(77)90555-5"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1159\/000293665"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(81)90313-6"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(15)33304-4"},{"key":"e_1_2_1_7_2","first-page":"99","article-title":"The detection of fetal growth retardation by technical and biochemical methods of surveillance","volume":"194","author":"Pfeiffer KH","year":"1990","journal-title":"Z Geburtshilfe Perinatol"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/0028-2243(87)90129-8"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/pd.1970101107"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-999718"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-999770"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003081-199009000-00017"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1159\/000293382"},{"key":"e_1_2_1_14_2","first-page":"407","article-title":"Biochemical and biophysical indices of follicular development in spontaneous and stimulated ovulatory cycles","volume":"75","author":"Fossum GT","year":"1990","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.246.6.590"}],"container-title":["Journal of Clinical Laboratory Analysis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fjcla.1860060102","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jcla.1860060102","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,24]],"date-time":"2023-10-24T03:15:21Z","timestamp":1698117321000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jcla.1860060102"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1992,1]]},"references-count":14,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1992,1]]}},"alternative-id":["10.1002\/jcla.1860060102"],"URL":"https:\/\/doi.org\/10.1002\/jcla.1860060102","archive":["Portico"],"relation":{},"ISSN":["0887-8013","1098-2825"],"issn-type":[{"value":"0887-8013","type":"print"},{"value":"1098-2825","type":"electronic"}],"subject":[],"published":{"date-parts":[[1992,1]]}}}
