Saturation of the \"stripped\" binding sites of transcortin is accomplished by equilibrating the sample with a definite amount of labeled cortisol of low specific activity (0.1 muCi/mug). Transcortin-bound [4-14C]cortisol is isolated by gel filtration over Sephadex G-50 at 4 degrees C and measured by liquid scintillation counting. The cortisol-binding capacity of transcortin is calculated directly on the basis of the known specific activity of cortisol. The modification described eliminates methodological disadvantages associated with the original gel filtration procedures, i.e. the possible interference of various endogenous steroids with cortisol binding to transcortin, and the necessity of fluorometric or colorimetric determination of protein-bound cortisol. The values of the cortisol-binding capacity of transcortin in plasma obteined by this simplified assay are in close agreement with results reported in the literature (mean +/- S.D.): healthy males 261 +/- 23 mug/l) of transcortin-bound cortisol (n = 13), healthy nonpregnant females 255 +/- 31 mug/l (n = 15), and pregnant females prior to delivery 560 +/- 82 mug/l (n = 12).</p>","PeriodicalId":23822,"journal":{"name":"Zeitschrift fur klinische Chemie und klinische Biochemie","volume":"13 7","pages":"291-7"},"PeriodicalIF":0.0,"publicationDate":"1975-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/cclm.1975.13.7.291","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12365025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In comparative once-through perfusions with FC 43 emulsion or albumin solution as perfusion medium, the clearance rates of oestrone and its metabolites were determined. In perfusions with FC 43, the clearance of oestrone was lower, and the metabolites formed in the liver were more concentrated in the outflowing medium than in perfusions without fluorocarbon. This can be explained by the high affinity, even of conjugated oestrogens, to FC 43, which is established by equilibrium dialysis and partition coefficient. The results presented here show that the fluorocarbon has a strong influence of its own on the metabolism of steroids in the isolated perfused liver.
