The immunobiochemical studies were conducted in a group of 98 production workers engaged in polyvinyl chloride manufacture from ethylene (group A workers) and in a group of 59 vinyl chloride workers from a chemical plant employing classic production technology from acetylene (group B workers). Both groups of workers were matched by age (group A workers: 37.7 +/- 8.66 years; group B workers: 34.9 +/- 11.2 years) and average exposure length (group A workers: 8.6 +/- 3.0 years; group B workers: 10.7 +/- 8.4 years). All workers were examined for the serum concentrations of immunoglobulins IgG, IgA and IgM and acute reactants lysozyme (LYS), transferrin (TRF), ceruloplasmin (CPL), alpha-l-antitrypsin (AlAT), alpha-2-macroglobulin (A2M) and orosomucoid (ORO). The statistical analysis included calculations of means, standard deviations and 95% confidence intervals. Differences in means were evaluated by t-test, differences in the distribution pattern of values by F-test. Abnormality of values was assessed by comparisons to normal values valid in Czechoslovakia. Group A worked in conditions meeting the MAC 10 mg VC.m-3 comparing with group B workers had elevated levels of IgG (P less than 0.005), IgA and IgM (P less than 0.001 both). Group B workers differed from group A workers by exhibiting significantly elevated levels of AlAT, and CPL. (P less than 0.001). The differences in the frequency of abnormal values between group A and group B worked in substantially less favourable hygienic conditions were significant for immunoglobulins elevated in group A and for ORO (P less than 0.01) and CPL (P less than 0.001) elevated in group B. The possible relationship of these immunobiochemical findings with the degree of vinyl chloride exposure are critically analyzed.

The authors determined, by an immunochemical method, the alpha-1-antitrypsin, Gc globulin, prealbumin, albumin, haemopexin, transferrin, haptoglobin, IgA, IgG, ceruloplasmin, alpha-2-macroglobulin contents of 98 follicular fluids, 10 peritoneal fluids and 24 blood sera. Out of these proteins analysed, change in the concentration of alpha-1-antitrypsin showed correlation with the maturity and fertilisation of the oocyte. The alpha-1-antitrypsin content was 1.6 +/- 0.26 g/l in the case of mature oocytes, and 3.1 +/- 1.12 g/l in the case of immature ones. Fertilisation was also concomitant of low alpha-1-antitrypsin levels.

The serum concentrations of selected trace elements and proteins in cord blood from 17 newborn infants whose mothers were habitual smokers were compared with values from 22 infants of non-smoking mothers. All the mothers were healthy with normal pregnancies and deliveries. Cigarette smoke exposure was verified by determinations of nicotine, cotinine and thiocyanate concentrations in cord blood. Infants of smoking mothers had a slightly lower mean birth weight (3490 +/- 430 g) than control infants (3780 +/- 460 g). Infants of smokers had lower serum iron (p = 0.05) and prealbumin (p less than 0.05), but higher serum copper (p less than 0.05) and ceruloplasmin (p less than 0.01) levels than the controls. Infants of smoking mothers tended to have higher levels of the acute-phase reactants alpha-2-macroglobulin and orosomucoid, but lower levels of albumin, transferrin and retinol-binding-protein, although differences were not statistically significant.

The authors present a system for the appraisal of the nutritional and inflammatory condition in patients suffering from cystic fibrosis (CF) in the phase of apparent inactivity of pulmonary infection, using a system of indices based on the quantification of some plasmatic proteins. The plasmatic appraisals of 4 visceral proteins (albumin, thyroxine-binding prealbumin, retinol-binding protein and transferrin) and, as well, of 5 proteins of the acute phase (alpha-1-acid glycoprotein, alpha-1-antitrypsin, alpha-2-macroglobulin, haptoglobin and ceruloplasmin) were obtained in a control group of 16 healthy children and in another of 14 children affected by CF. With the proteic plasmatic appraisals of the control group, the knowledge of their biological value and after a statistical-mathematical analysis, the most sensitive, specific and independent proteins were determined for evaluating the nutritional and inflammatory condition, obtaining two simple formulas which were denominated Nutritional-Inflammatory Prognostic Indices (NIPI) A and B (NIPI A = alpha-1-acid glycoprotein + haptoglobin/albumin + prealbumin; NIPI B = haptoglobin/albumin). From the analysis of the results, it can be deduced that the children with CF are affected by an inflammatory process, very probably infectious.

The growth of Treponema denticola in a complex medium was stimulated by human ceruloplasmin and, to a lesser extent, albumin, alpha-1-antitrypsin, alpha-1-acid glycoprotein, and alpha-2-macroglobulin. Human ceruloplasmin could stimulate growth of T. denticola as well as or better than 5% rabbit serum, with a dose-response relationship of between 1 and 5 mg of ceruloplasmin per ml of culture medium. These results suggest that ceruloplasmin could substitute for rabbit serum in stimulating the growth of T. denticola.

Binding curves for the adsorption of plasma fibronectin, alpha-1-antitrypsin, alpha-2-macroglobulin, ceruloplasmin, transferrin and bovine serum albumin to plain and to hydroxylated polystyrene surfaces were measured. These curves were correlated with the adhesion of BHK cells and leucocytes to these adsorbed protein surfaces in protein-free culture media. Hydroxylated polystyrene adsorbed less of alpha-1-antitrypsin, alpha-2-macroglobulin and albumin than the plain polystyrene. On the other hand the hydroxylated surfaces bound more fibronectin than the plain polystyrene surfaces. Hydroxylated polystyrene surfaces were also more adhesive for both BHK cells and leucocytes than plain polystyrene: a result confirming earlier work. The competition of fibronectin for adsorption to plain polystyrene with alpha-1-antitrypsin, alpha-2-macroglobulin and ceruloplasmin was measured and correlated with effects on cell adhesion. The results suggest that the low adhesiveness of BHK cells and leucocytes on plain polystyrene in sera-containing media is due both to the low binding of fibronectin and to the binding of serum albumin, alpha-1-antitrypsin and alpha-2-macroglobulin. The relative unimportance of fibronectin in adhesion to these surfaces is shown by the finding that cell attachment will not occur to polystyrene surfaces that have bound high levels of the antiadhesive proteins in the presence of fibronectin, even though attachment will occur in the absence of fibronectin provided that the antiadhesive proteins are lacking.

Seventy six patients with chronic inflammatory rheumatism were treated with various non-steroid anti-inflammatory drugs for 5 to 7 days. The average variations of several serum proteins were studied. The variation of haptoglobin remained nil. Those of other serum proteins remained negative and significantly different from zero, distributed from the greatest to the smallest value of the degree of statistical significance as follow : ceruloplasmin (p < 0.0001), orosomucoide (p < 0.02), fibrinogen (p < 0.02) alpha-2-macroglobulin (p < 0.04) and alpha-1-antitrypsin (p < 0.05). The study of the partial results showed the variability of the degree of significance of the serum proteins in relation to the non-steroid anti-inflammatory drugs. The practical interest of these serum protein seemed low to measure in the short term, the efficacy of non-steroid anti-inflammatory drugs. Their interest in long term studies remains to be demonstrated compared with that of the measurement of the sedimentation rate by the technic of the sigma E.S.R.

Cerebrospinal fluid, G, A, M, immunoglobulins, alpha-2-macroglobulin and ceruloplasmin levels were determined by a nephelometric Laser method of a control group of 21 adult patients strictly suffering from a "slipped disc" disease. The same CSF parameters were studied on a second group of 90 patients including adults and children with normal CSF proteins levels (< 500 mg per liter). Normal values were established according to the different age groups. Results were given in milligrams per liter and nanomols per liter.

Immunoadsorbents bind immunoglobulins, immunocomplexes or immunocytes. Their clinical use could become a new therapeutic principle for diseases in the pathogenesis of which antibodies or immunocomplexes play an important part. Immunoadsorbents are also being tested in the hope that they can at least partially replace the plasmapheresis-plasma exchange therapy at present practised. A report is given on in-vitro studies using protein-A-bearing staphylococci, strain COWAN I. The bacteria bind IgG selectively, IgM to a small extent, IgA, IgD and IgE hardly. The majority of the other plasma proteins tested (e.g. albumin, transferrin, ceruloplasmin, alpha-2-macroglobulin, beta-lipoprotein, alpha-2-glycoprotein, alpha-1-antitrypsin) are bound only non-specifically and in small quantities. The staphylococci can react with acid solutions (glycin-HCl buffer, acetic acid) in several ways. The activation of the complement system by IgG binding to protein A is one of the problems to be solved before immunoadsorbents an be used clinically.

Reed-Sternberg cells in the lymph nodes from five patients with Hodgkin's disease were studied. Indirect immunofluorescence on fixed sections with a monospecific anti-serum to fibronectin revealed abundant cytoplasmic fibronectin in approximately 90% of the Reed-Sternberg cells. In addition, the cells were shown by immunofluorescence to contain polyclonal IgG; however, factor VIII antigen, albumin, fibrinogen, alpha-2-macroglobulin, anti-thrombin III, and ceruloplasmin were not present. The abundant cytoplasmic fibronectin suggests that Reed-Sternberg cells are derived from tissue macrophages.
