The effect of various hormonal contraceptives on the thyroid hormone level, plasmatic and thrombocytic coagulation, cholesterol and ceruloplasmin levels and the activity of gamma-glutamyl transpeptidase was investigaged by the changes produced by long term cyclic estrogen-gestagen therapy on the metabolism of the organism. The free thyroxine index and the total cholesterol were within the normal range. The thyroxine binding index at 44% was above the normal level and the mean value was significantly raised. The ceruloplasmin concentration in the serum was also significantly increased. Pointers to a general hypercoagulability could not be ascertained with a statistical significance.

Serum protein components were evaluated by the specific radial immunodiffusion technique in a number of protein energy malnourished infants and young children, as well as in a group of parallel controls. Results show a drop in both serum prealbumin and albumin in concordance with the severity of the condition in both KWO and marasmus. Serum level of varies as 1-acidic glycoprotein was elevated, being more marked in KWO than in marasmus. Serum oc1-antitrypsin, haemopexin, ceruloplasmin and transferrin were all reduced but to a varying extent in both KWO and marasmus. The levels of serum IgA and IgM were above normal in all disease entities except for a slight decrease of IgA in 2nd grade marasmus. On the other hand, serum IgG was reduced in the majority of cases. The ratio of serum cerutoplasmin to transferrin in KWO was found to be of diagnostic value in different grades of the disease.

In the serum of 27 patients with malignant lymphogranulomatosis the authors determined the serum level of glycoproteid-carbohydrate components (hexose, hexosamine, sialin acid, and seromucoid) and the concentration of 11 different glycoproteids. In the early stage of the disease the immunoglobulin level is moderately increased in the serum, whereas a diminution can be observed in stage IV. The concentrations of ceruloplasmin, alpha-2-macroglobulin and orosomucoid were already increased significantly in stage III. The increase did not continue in stage IV. In the final stage of the disease the concentrations of alpha-1-antitrypsin and haemopexin turned out to be increased considerably. A significant decrease in the transferrin level could be registered in stage III with this diminution also continuing in the further course. Changes of beta-C-globulin and haptoglobin concentrations could not be evaluated statistically. The content of carbohydrate components in the glycoproteids will already increase in the early stage of the disease with this increase continuing in the further course. Among histological types there was a more significant increase of immunoglobulins in those forms rich of lymphocytes.

The authors have elaborated a biochemical technique for the assessment of the selectivity of proteinuria by means of the clearances of ceruloplasmin, haptoglobin and albumin. The results obtained in 69 patients were compared to those established by the method of Cameron and Blanford, as well as by the clearance of alpha2-macroglobulin. No significant differences were found in the indices of proteinuria, as determined by the proposed biochemical technique and by the method of Cameron and Blanford. Thus the diagnostic value of both methods to assess the selectivity of proteinuria could be considered as equal. The additional measurement of the selectivity of proteinuria by means of proteins with considerably high molecular weight (haptoglobin, alpha2-macroglobulin) gave the possibility of recording cases with severely impaired glomerular permeability. In this respect, the use of the clearance of haptoglobulin, particularly the phenotype Hp 2--2, provided valuable diagnostic information in cases in which the routine methods gave borderline values for the index of proteinuria.

In thirty children hospitalized with acute benign, short-duration gastroenterocolitis, no obligate pathogens were isolated from stools. Five bleedings were established from each patient in order to obtain the protein profiles of albumin, orosomucoid, haptoglobin, alpha2-macroglobulin, ceruloplasmin, transferrin, C3-component, C-reactive protein, immunglobulins IgG, IgA, IgM and IgD. The proteins were quantitated by the single radial immunodiffusion method. The initial drop in some of the proteins followed may be related to general protein loss, negative nitrogen balance or hemodilution. The absence of a significant increase in all the investigated immunoglobulin classes contrasted with remarkable increase in haptoglobin and orosomucoid, both reaching normal levels in late convalescence. C-reactive protein could be demonstrated in half of the children showing early normalization with disappearance of clinical symptoms. In contrast to ceruloplasmin and C3- component, alpha2-macroglobulin was not involved in the acute phase protein reaction.

Pleural effusions from 105 patients with malignant and nonmalignant diseases were examined for tumor cells, content of CEA, beta2 microglobulin, ceruloplasmin, alpha2 macroglobulin, orosomucoid, lysozyme, and hexosaminidase. Only CEA and beta2 microglobulin determinations were of diagnostic value. CEA concentrations greater than 11 ng/ml were found only in malignant effusions. Beta 2 microglobulin values were increased in pleural effusions due to lymphoma or immune diseases. Measurement of CEA and beta2 microglobulin in addition to the cytologic examination could increase the diagnostic significance of the analysis of pleural effusions.

Poly(A) containing rat liver 21S RNA homogeneous in polyacrylamide gel electrophoresis under denaturing conditions and stimulating the synthesis of ceruloplasmin in a cell-free proteinsynthesizing system, was used as a template for reverse transcription in the presence of T10 primer and highly purified reverse transcriptase from avian myeloblastosis virus. The cDNA made this way was characterized by means of hybridization kinetics with mRNA, by melting of the hybrids formed and by chain length measurements. To increase the degree of representativity, the ceruloplasmin mRNA was fragmented by mild alkaline treatment, enzymatically polyadenylated and transcribed. The cDNA made was fully characterized and the kinetic complexity measured by hybridization with the mRNA was found to be equal to 2300 nucleotides as compared with the value of 3000 nucleotides is expected from gel electrophoresis data. The observed difference may indicate the presence of repeated sequences in the given mRNA. The sufficient representativitness of the synthesized cDNA and its specificity with respect to ceruloplasmin mRNA allows to use it as a molecular probe to study the ceruloplasmin gene structure.

A number of soluble proteins contained in human aortic intimal tissue was extracted into buffered saline (pH 7.4) and identified and quantitated by immunoelectrophoresis and immunodiffusion. The proteins included IgA, IgG, IgM, B1C (C3), alpha 1-antitrypsin, alpha 2-macroglobulin, fibrinogen, albumin, LDL, HDL, alpha 1-acid glycoprotein, beta 2-glycoprotein, transferrin and ceruloplasmin. The concentration of soluble proteins was significantly higher in the atherosclerotic intima than in the normal intima. The diseased intima also contained a small amount of tissue-bound IgG, IgA and B1C which was extractable with citrate buffer at pH 3.2. The vascular band IgG, and B1C were shown by enzymatic and immunohistochemical studies to be closely associated with the collagenous tissue of the plaque. The Ig contained in the atherosclerotic plaque may be derived in part from the biosynthesis of Ig by the artery, since the incorporation of 14C-labeled leucine into IgG by the atheromatous plaque was demonstrable by radioimmunoelectrophoresis. In contrast to the diseased artery, the normal artery did not synthesize IgG and did not contain vascular bound IgG or complement. However, the normal artery was capable of fixing IgG and B1C eluted from the diseased artery. The present studies suggested that the IgG contained and synthesized by the plaque might represent an immune response to an endogenous or exogenous antigen closely associated with plaque collagen. IgG and B1C either alone or in the form of an immune complex also may play an important role in phagocytosis in the plaque and thereby influence the course of atherosclerosis. The proteolytic inhibitors, alpha 1-antitrypsin and alpha 2-macroglobulin, found in relatively high concentrations in the plaque, could enhance fibrosis of the lesion because of thier known inhibitory effects on collagenase and elastase.

A surface coat of host serum proteins was detected on virulent Treponema pallidum by sodium dodecyl sulfate-gel electrophoresis. The loosely associated serum proteins could be removed by repeated washings in a protein-free medium. Washed T. pallidum retained the ability to readsorb numerous host proteins from rabbit serum as well as iodinated rabbit or human albumin. In addition, various avidly associated host serum proteins including albumin, alpha(2)-macroglobulin, transferrin, ceruloplasmin, immunoglobulin G, immunoglobulin M, and C3 were identified on the outer envelope of washed treponemes by an immunoadsorbent technique with protein A-bearing staphylococcus. Hyaluronidase treatment did not remove the avidly associated host proteins from the surface of washed treponemes, whereas trypsin treatment resulted in decreased levels of agglutination. Electrophoretic patterns of trypsin-treated treponemes showed that treponemal proteins as well as adsorbed host proteins were released concurrently by protease digestion. Reacquisition studies involving alpha(2)-macroglobulin and transferrin suggested the presence of noncompetitive binding sites for serum proteins on the treponemal outer envelope. Finally, differences among the T. pallidum preparations from individual rabbits with respect to incorporation of [(35)S]methionine, extent of agglutination with antisera, and length of time required for removal of avidly associated host proteins by trypsin treatment indicated biological variability among the treponemal populations.
