All seven pure yolk sac tumors of gonadal and extragonadal origin tested showed a bright positive fluorescence for alpha-fetoprotein in the tumor tissue. A positive reaction was seen in both the tumor cells and the hyaline globules. In all cases, however, the positive fluorescence was distributed in some focal areas of the tumor tissue. Certain tumor cells showed a strong granular intracytoplasmic fluorescence, whereas others showed a weak or a negative fluorescence. The fluorescence-positive tumor cells were located mainly in the areas rich in fluorescence-positive hyaline globules. Besides alpha-fetoprotein, certain plasma proteins--albumin, alpha-1 antitrypsin, and transferrin--were also demonstrated in all five yolk sac tumors tested. The pattern of the distribution of positive fluorescence was basically similar to that of alpha-fetroprotein. Other plasma proteins--orosomucoid, haptoglobin, Gc-globulin, alpha-2 macroglobulin, hemopexin, and ceruloplasmin--were present in certain tumors, and were distributed mainly in a limited number of hyaline globules. Both IgG and IgA were present in two tumors of ovarian origin. The immunoglobulins were for the most part present in extracellular hyaline globules, suggesting that these are taken up from the circulation. Test for fibrinogen, beta-lipoprotein, IgM, IgE, beta-1C/beta-1A and beta-1E globulins were negative or questionable. In a hepatoblastoma, tests for alpha-fetoprotein were positive, but those for other plasma proteins were negative. Fine granular fluorescence was seen in each hepatocellular tumor cell. Mesenchymal elements were virtually unstained.

Sera were sampled from 83 people (pre- and post-menopausal women and men). Climacteric symptoms of 23 women were treated with conjugated estrogen. Sera were sampled serially until the 21st day of estrogen administration. Serum concentrations of 40 protein components were measured by micro single radial immunodiffusion. The serum proteins were classified into 5 types according to changes after menopause and estrogen therapy, respectively. Type 1 (decreased after menopause and increased by estrogen; alpha 1-antitrypsin, alpha 2-HS - glycoprotein, beta 2-glycoprotein III, Gc-globulin, alpha 1-lipoprotein and alpha 2-AP-glycoprotein), type 2 (unchanged and increased; ceruloplasmin), type 3 (increased and decreased; alpha 1-acid glycoprotein, haptoglobin, serum amyloid P-component, Zn-alpha 2-glycoprotein, beta-lipoprotein and C1-components), type 4 (unchanged and decreased; hemopexin, antithrombin III, beta 2-glycoprotein I, prealbumin and retinol-binding-protein), type 5 (unchanged by estrogen; immunoglobulin M (IgM), IgG and others). Estrogen replacement therapy restored pre-menopausal levels of serum proteins, types 1 and 3. However, estrogen therapy was associated with significantly abnormal levels of proteins, types 2 and 4 in post-menopausal women. Serum levels of type 1 proteins and some type 5 proteins (IgM, alpha 1B-glycoprotein, C9-component and alpha 2-macroglobulin) were higher in pre-menopausal women than in men, whereas type 3 proteins were the opposite.

Crossed immunoelectrophoresis (X-IEP) revealed several abnormalities in serum proteins from patients with adult respiratory distress syndrome (ARDS), tuberculosis (TB), and cystic fibrosis (CF). The two quite different kinds of pulmonary disease, one acute (ARDS) and the other chronic (TB and CF) exhibited serum changes specific for each disease and abnormalities associated with inflammation and pathogenesis, in general. In ARDS sera, most proteins were extremely low, presumably due to leakage into the lungs through damaged tissue, while the acute-phase proteins, orosomucoid, alpha 1-antitrypsin, alpha 1-antichymotrypsin, and haptoglobin, were markedly high when compared to the overall protein pattern. The extremely high alpha 1-antichymotrypsin values were not seen in corresponding TB and CF sera. Numerous TB patients had elevated alpha 1-antitrypsin, alpha 1-antichymotrypsin, and haptoglobin, but only the alpha 1-antitrypsin population mean was significantly different from normal. Gc-globulin, ceruloplasmin, and beta-lipoprotein were higher and alpha 1-lipoprotein and inter-alpha-trypsin inhibitor lower than normal. All other quantitative serum changes were not statistically significant. Surprisingly, all TB patients belonged to the Gc-1-1 genotype in contrast to the Gc-1-1, Gc-1-2, Gc-2-2 polymorphisms of the other populations. CF homozygote sera revealed statistically significant increases in the acute-phase proteins, alpha 1-antitrypsin, alpha 1-antichymotrypsin, and haptoglobin, while orosomucoid, transferrin, IgA, and IgG tended to be higher than normal. The tendency for higher levels of transferrin indicated possible iron deficiency in some patients. In contrast, prealbumin, alpha 1-lipoprotein, and inter-alpha-trypsin inhibitor were significantly depressed in CF patients. CF heterozygotes shared the decrease of alpha 1-lipoprotein with the patients while exhibiting small but significant depressions of alpha 2-macroglobulin and IgG. Though not statistically significant, lowered concentrations of alpha 1-antitrypsin were evident for the heterozygotes.

Urine was collected from 6 healthy male adults at rest and from 20 male adults after a marathon race (25 miles). The concentrated urines were quantitatively analyzed, by single radial immunodiffusion, for their content in 12 different plasma proteins: tryptophan-rich prealbumin, albumin, alpha(1)-acid glycoprotein, alpha(1)-antitrypsin, ceruloplasmin, haptoglobin, Gc-globulin, transferrin, hemopexin, beta(2)-glycoprotein I, gammaA-globulin, and gammaG-globulin.Albumin, gammaA-globulin, and gammaG-globulin represent the major part of the plasma proteins detected in normal urine excreted by humans at rest (12, 0.5, and 2.5 mg respectively, out of a total excretion of 17.5 mg of plasma proteins per 24 hr). The other plasma proteins were excreted at a lower rate (< 0.4 mg/24 hr). The relative content of tryptophan-rich prealbumin, alpha(1)-antitrypsin, Gc-globulin, transferrin, and gammaG-globulin was lower in normal urine than in normal serum, whereas that of alpha(1)-acid glycoprotein, beta(2)-glycoprotein I, and gammaA-globulin was higher. The ratio of gammaG-globulin to gammaA-globulin was 4.9:1. When plotted on a logarithmic scale, no direct relationship between the molecular weight of a protein and the value of its renal clearance could be observed.Strenuous exercise increased (up to 50-fold) the excretion of plasma proteins which represent 82% of the total proteins found in urine, instead of 57% in urine collected from humans at rest. There was particularly a significant rise of tryptophan-rich albumin, albumin, alpha(1)-acid glycoprotein, transferrin, gammaA-globulin, and gammaG-globulin (0.26, 127, 11.8, 3.3, 1.2, and 2.0 mug respectively, out of a total excretion of 167 mug of plasma proteins per min). The ratio of gammaG-globulin to gammaA-globulin was 16:1. After exercise, the renal clearance of proteins increased from 2 to 40 times, but, as for the urine of normal subjects at rest, no direct relationship between molecular weight and renal clearance could be observed.

We have grown a human hepatoma cell line, designated as HA22T/VGH, from a 52-yr-old male hepatoma patient since July 1, 1980. This cell line has been subcultured more than 100 passages. The chromosome analysis of HA22T/VGH indicated that the chromosome numbers varied from 70 to 146, with the mode of 73. Methylcellulose soft agar assay showed that approximately 40% of the HA22T/VGH cells formed colonies. The HA22T/VGH produced tumors in nude mice. Histopathological studies of the tumor revealed the arrangement of hepatoma. Detected by the complement fixation method HA22T/VGH cells secreted ceruloplasmin, Factor B, C3, C4, Gc-globulin and alpha 1-acid-glycoprotein. These cells contained the liver associated enzymes: alanine amino transferase, tyrosine amino transferase and gamma-glutamyl transferase. HBsAg and alpha-fetoprotein were not detectable in the HA22T/VGH culture media or cell lysates by the radioimmunoassay.

Immunologic analyses of urinary proteins in patients with gestosis and related obstetrical conditions were performed and urinary protein patterns were compared with blood plasma protein patterns. Many kinds of proteins could be detected in urine of patients with gestosis beside albumin. Therefore, "proteinuria" should be chosen to characterise this state instead of the term "albuminuria". Generally speaking, when a total volume of protein contained in urine increases, its types or subfractions also increase in urine. Next to albumin, the most commonly detected proteins in urine of patients with gestosis were transferrin, IgG, inter-alpha-trypsin inhibitor, alpha 1-antitrypsin, IgA, alpha 2-HS-glycoprotein, alpha 1-acid glycoprotein, Gc-globulin, alpha 1-antichymotrypsin, hemopexin, ceruloplasmin, prealbumin, haptoglobin, anti-thrombin III, Cl-inactivator, IgM, and alpha 2-macroglobulin, in the descending order of their occurrence. Proteins that promptly became negative in urine of gestosis patients after delivery were inter-alpha-trypsin inhibitor, IgA, and ceruloplasmin. On the other hand, proteins most apt to persist in urine were albumin, alpha 2-HS-glycoprotein, and IgG. Generally speaking, lower molecular weight proteins were likely to persist in urine after delivery. Simultaneous determination of blood plasma and urinary proteins was performed for 18 kinds or subfractions of protein. A prognostic value of renal protein clearance was discussed.

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.

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.

To search out novel biomarkers for monitoring diabetes prognosis, we examined the effect of hypoglycemic fungal exopolysaccharides (EPS) on the differential levels of plasma proteins in streptozotocin-induced diabetic rats. The orally administrated EPS exhibited an excellent hypoglycemic effect, lowering the average plasma glucose level, and increasing insulin secretion in diabetic rats. The 2-DE analysis of rat plasma demonstrated that about 500 visualized spots were differentially regulated, of which 20 spots were identified as principal diabetes-associated proteins. The distinct effect of diabetes induction on the pattern of rat plasma proteins includes the down-regulation of albumin, apolipoprotein E (Apo E), alpha1-inhibitor-3, fetuin beta, Gc-globulin, hemopexin, vitronectin, and transthyretin (TTR) monomer, and the up-regulation of Apo A-I, Apo A-IV, ceruloplasmin, alpha1-antitrypsin, serine protease inhibitor III, and transferrin. Those protein levels were interestingly restored to those of healthy rats by EPS treatment, although the order of magnitude of the changes differed widely. Two proteins of interest showed distinct differential expression with opposite trends: TTR tetramer was significantly down-regulated and immunoglobulin (Ig) kappa light chain was significantly up-regulated upon diabetes induction, both of which were also normalized to those of healthy groups after EPS treatment.
