Three cortisol fractions, protein-unbound (U-F), transcortin-bound (Tr-F) and albumin-bound cortisol (Al-F) were measured in patients with dysproteinemia by a newly devised isocolloidosmolar equilibrium dialysis method. Total cortisol (Total-F) concentrations in patients with liver cirrhosis (LC), anorexia nervosa (AN) and cachexia due to cancer (CA) were higher than in normal subjects, and those in patients with nephrotic syndrome (NS) and multiple myeloma (MM) remained within the normal range. In all groups of patients, the U-F concentration, which is believed to be the sole active fraction of cortisol, showed significantly higher values than in the normal subjects. We, therefore attempted to find which of the two binding proteins contributes to the elevated U-F concentrations. Concentrations of each cortisol fraction are greatly changed by alterations in the Total-F concentration. We therefore compared the Tr-F against Total-F and Al-F, and U-F against Total-E of patients with those of normal subjects. It was found that decreased transcortin-binding and not albumin-binding in the patients with cirrhosis, nephrotic syndrome and myeloma contributed to an increase in the U-F concentration. Although decreased binding of albumin due to hypoalbuminemia was found in LC, NS, MM, CA and AN, it had relatively little effect on cortisol distribution in the serum.

Capillary zone electrophoresis (CZE) offers the potential for automating serum protein electrophoretic analysis traditionally performed on standard thin-layer agarose gels. The following describes the use of CZE compared to agarose gel electrophoresis (AGE) for the detection of dysproteinemia and paraproteinemia in a clinical study involving 240 patients. The study includes within-run and between-run reproducibility data on the Paragon CZE 2000 Clinical Capillary Electrophoresis System, in addition to concordance data between the two methodologies. Paraprotein quantitation studies comparing AGE versus CZE were also performed. Reproducibility for the automated CZE system was superior to the AGE system. Improved reproducibility for the CZE method is largely due to measuring protein absorbance directly at 214 nm versus the traditional AGE method that measures the amount of dye adsorbed to protein. Reproducibility data as percent coefficient of variance (% CV) for the five classic bands in a normal control serum for between-run precision ranged from 1.2 to 4.5% for CZE compared to AGE, which ranged from 3.8 to 8.0% CV. Concordance studies between AGE and CZE involving dysproteinemias including hypogammaglobulinemia, polyclonal and monoclonal gammopathies, acute and chronic inflammation, nephrosis, hepatodegenerative disease, cirrhosis, and iron deficiency anemia showed 96% agreement. Paraprotein classification, which compared the CZE immunosubtraction method to immunofixation electrophoresis (IFE) on agarose, showed 100% agreement. Certain dysproteinemias involving beta lipoprotein were in partial concordance due to the inability of the CZE procedure to detect this component. Detection limits for monoclonal gammopathies, providing they were not comigrating with other proteins, were IgG 50 mg/dL, IgM 75 mg/dL, and IgA 75 mg/dL. Paraprotein quantitative studies between the two methods showed less than a +/- 0.2 g/dL variation.

Morphofunctional state of the liver (in particular, indexes of carbohydrate, protein, and fat metabolism, structural elements and condition of vascular endothelium of the liver) in female rats subjected to immobilization stress during pregnancy, has been studied. Morphological changes in the liver include discomplexation of beam-radial structure, pyknosis of hepatocyte nucleus, increased regeneration activity of parenchyma, and increased stromal parenchymal index. Functional disorders are manifested by development of dysproteinemia, hyperlipidemia, hyperglycemia, and increased activity of organo-specific liver enzymes. It testifies to risk of fibrosis and diffuse nodular cirrhosis development in the animals, as well as diabetes mellitus of type II in the future.
