Changes in the concentration of some serum acute phase proteins (alpha 1-antitrypsin, alpha 2-macroglobulin, complement C3, haptoglobin, ceruloplasmin, transferrin, albumin and hemopexin), thyroxine-binding globulin, retinol-binding globulin, plasminogen and Gc-globulin are reported in two separate series of Chinese, male schizophrenic patients and healthy controls. In the first series, 41 healthy blood donors and 98 schizophrenic patients in different stages of the disease were investigated. The second series consists of a random sample of 50 acutely ill schizophrenic patients and a second group of healthy subjects. The concentrations of these serum proteins were measured by rocket immunoelectrophoresis in agarose gel. Increased levels of serum alpha 1-antitrypsin, alpha 2-macroglobulin, haptoglobin, ceruloplasmin, and thyroxine-binding globulin were observed in both series of patients when compared to their respective controls. Albumin, transferrin and retinol-binding protein levels were reduced in patients in both series. Hemopexin levels were increased only in the acutely ill patients while complement C3 was decreased in the chronically ill patients. No changes were observed in the Gc-globulin levels of all groups of patients. With the exception of complement C3, the changes observed in the levels of these serum proteins were appropriate for that of an acute phase response.

Two-dimensional (2-D) gel analysis was used to examine differences in the levels of 19 plasma proteins: before and after an acute inflammatory reaction (parenteral typhoid vaccination) in normal subjects, between rheumatoid arthritis (RA) patients and normals and in RA patients treated with tenidap (120 mg) and piroxicam (20 mg). Typhoid vaccination increased levels of SAA, haptoglobin alpha1, haptoglobin alpha2, haptoglobin beta and alpha1-anti-chymotrypsin but decreased transthyretin and apolipoprotein E. In RA patients, serum amyloid A (SAA), haptoglobin alpha2, haptoglobin beta, alpha1-antichymotrypsin and C3 proactivator levels were elevated while apolipoprotein A-I, apolipoprotein A-IV, transthyretin, Gc-globulin, alpha2-HS glycoprotein, alpha2-macroglobulin and alpha1-B glycoprotein levels were decreased, compared to normals. Compared to piroxicam, tenidap lowered levels of alpha1-antiprotease and SAA but raised the levels of transthyretin, Gc-globulin, alpha2-HS-glycoprotein and alpha2-macroglobulin in RA patients. C-reactive protein (CRP) could not be quantified on 2-D gels but, when measured by rate nephelometry, levels were reduced after treatment with tenidap compared to piroxicam. The general pattern of the acute phase protein response to an acute inflammatory response to typhoid vaccination is similar to that in the chronic inflammatory condition, RA. The impact of tenidap on both positive and negative acute-phase proteins in RA patients could clearly be distinguished from that of piroxicam.

The separation of human serum globulins into individual components was investigated by capillary zone electrophoresis (CZE) using a linear polyacrylamide-coated capillary at pH 7.4. Prior to CZE analysis of globulin components present in serum, it was found that it was necessary to remove albumin. Preparation of albumin-depleted human serum with a HiTrap Blue column allowed the detection of alpha- and beta-globulin components as a series of peaks. Almost all the peaks, both narrow and broad, observed in CZE analysis could be assigned to six globulin components (alpha1-acid-glycoprotein, alpha1 -antitrypsin, haptoglobin, alpha2-macroglobulin, Gc-globulin, and transferrin) by using the technique of antibody-based indirect detection. The CZE results, obtained from serum preparations from three healthy adults and six patients, showed that the CZE system might be capable of detecting qualitative differences among individuals with regard to individual globulin components.

The effect of adjuvant arthritis (AA) on the pattern of rat serum proteins includes the upregulation of haptoglobin, orosomucoid, alpha2-macroglobulin, serine protease inhibitor-3, thiostatin, alpha1-antitrypsin, C-reactive protein, and the downregulation of kallikrein-binding protein, alpha1-inhibitor III, apolipoprotein A-I, alpha2-HS-glycoprotein, albumin, apolipoprotein A-IV, transthyretin and transferrin. Minor changes (+/- 20%) are observed for Gc-globulin, ceruloplasmin, and alpha1-macroglobulin. AA thus grossly resembles the acute inflammatory response elicited by the injection of turpentine, although the changes in the levels of negative acute-phase proteins (APP) are smaller in acute inflammation. Indomethacine and ibuprofen inhibit the effects of arthritis on the synthesis of rat serum proteins in different ways: The former is, on average, three times as effective as the latter. Each drug interferes differently with different proteins. In animals without AA, both nonsteroidal anti-inflammatory drugs (NSAID) mimic the inflammatory pattern to a certain extent, with more effect on the negative than on the positive APPs. Overall, the shifts in serum protein levels parallel changes in inflammatory parameters such as joint swelling and serum interleukin-6 (IL-6) activity. Protein quantitation after two-dimensional electrophoresis (2-DE) reveals some effects of the drugs per se which escape detection by other routine tests.

Human individual sensitivity to health-hazardous occupational factors and probability of developing chronic lung diseases depend on genetic variation of serum and erythrocytic proteins. The present work was aimed at studying the phenotypes of serum and erythrocytic proteins in patients with occupational respiratory diseases. We studied 7 highly polymorphic genetic systems the varieties of which may be connected with development of bronchopulmonary pathology (BPP) and the immune status of the body: proteinase inhibitor (Pi), third component of the complement (C3), transferrin (Tf), group-specific component of blood serum (Gc), haptoglobin (Hp), erythrocytic glyoxalase (Glo) and phosphoglucomutase (PGM) in patients with chronic bronchitis, silicosis, occupational bronchial asthma and in the control group consisting of Moscow population not exposed to occupational hazards and apparently healthy workers of an engineering plant. Considerable differences were revealed in genetic structure of the patients with bronchopulmonary pathology as compared with the apparently healthy people along a series of Integrated system: proteinase inhibitor (Pi), C3, Tf, Gc, PGM. Comparison of the study groups by significant differences in the aggregate of the genetic information obtained suggests that 5 (HP, C3, Tf, Pl, PGM1) of the 7 studied systems showed the hereditary features of silicosis. The gene carriers Hp*2, C3*F, PGM1*2-, TF*D, GC*R due to peculiar biochemical processes appear to have less adaptive potentialities and a greater likelihood of the disease on exposure to industrial factors. The examined patients with chronic bronchitis showed an increase in the variant of GC*2 and of a rare variants of proteins GC*R and Pi*S, the patients with occupational bronchial asthma showed an increase in the variant of Hp*2 and of a rare variant Pi*S. Such studies could be useful for assessment and forecast of individual risk of occupational diseases.

We applied proteomics technologies to analyze the cerebrospinal fluid of patients with schizophrenia. Such an analysis can result in the identification of proteins, which may play a role in the disease progress and thus lead to the discovery of clues of the etiology of schizophrenia. Cerebrospinal fluid from patients and controls was analyzed by two-dimensional gels and the proteins were identified by matrix-assisted laser desorption ionization mass spectrometry (MS) in the MS and MS/MS mode. 54 different gene products were identified, which were mainly plasma proteins. The level of apolipoprotein A-IV was significantly decreased in the schizophrenic patients compared to that in the controls. Little is known about the function of this apolipoprotein in the central nervous system. The levels of certain other proteins, like haptoglobin, fibrinogen, complement component 3, and Gc-globulin, were altered in the disease group as well, however, the changes did not reach a statistical significance.

Peritoneal membranes can be categorized as high, high average, low average, and low transporters, based on the removal or transport rate of solutes. In this study, we used proteomic analysis to determine the differences in proteins removed by different types of peritoneal membranes. Peritoneal transport characteristics in patients who received peritoneal dialysis therapy were assessed by a peritoneal equilibration test. Two-dimensional differential gel electrophoresis technology followed by quantitative analysis was performed to study the variation in protein expression from peritoneal dialysis effluents (PDE) among different groups. Proteins were identified by MALDI-TOF-MS/MS analyses. Further validation in PDE or serum was performed utilizing ELISA analysis. Proteomics analysis revealed ten protein spots with significant differences in intensity levels among different groups, including vitamin D-binding protein, complement C3, apolipoprotein-A1, complement factor C4A, haptoglobin, alpha-1 antitrypsin, immunoglobulin kappa light chain, alpha-2-microglobulin, retinol-binding protein 4 and transthyretin. The levels of vitamin D-binding protein, complement C3, and apolipoprotein-A1 in PDE derived from different groups were greatly varied (P<0.05). However, no significant difference was found in the serum levels of these proteins among different groups (P>0.05 for all groups). This study provides a novel overview of the differences in PDE proteomes of four types of peritoneal membranes. Vitamin D-binding protein, complement C3, and apolipoprotein-A1 showed enhanced expression in PDE of patients with high transporter.
