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.

Several serum proteins, such as prealbumin, protease inhibitors, immunoglobulins, metalloproteins and inflammatory glycoproteins were determined in the sera of heavily burnt patients by radial immunodiffusion. An increase of acute phase reactant glycoproteins (orsomucoid, haptoglobin, haemopexin, C-reactive protein), C3-complement, immunoglobulins, prealbumin and of the protease inhibitors (a1-antitrypsin, a2-macroglobulin) was found. For some proteins, such as prealbumin, haemopexin, immunoglobulins, this increase was preceeded by a decrease on days 3 to 5 post-burn. The time course of the increase was variable, faster for some patients and slower for others: orosomucoid, C-reactive protein, C3-complement reached peak values between days 6 and 8; immunoglobulins and hemopexin decreased then towards normal values. No significant increase was found for ceruloplasmin, transferrin, beta2-glycoprotein, a2-SH glycoprotein and GC-globulin. It is proposed that the selective overproduction of the above mentioned proteins may be related to the stimulation of acute-phase reactant protein synthesis by the liver as a result of tissue breakdown produced by the circulating proteases and especially by elastases and collagenases as was shown previously (Miskulin et al., 1978; Moati et al., 1978a).

Using single radial immunodiffusion, ten glycoproteins from non purulent pleural fluids have been estimated in different diseases. For five proteins (prealbumin, ceruloplasmin, alpha2HS-glycoprotein, transferrin, beta2-glycoprotein 1) the results have been found not to correlate with the causal disease. However for orosomucoid, alpha1-antitrypsin, haptoglobin, alpha2-macroglobulin and hemopexin, there was good correlation between proteins levels and aetiology. The glycoprotein concentration was low in mechanical effusions from cirrhosis and chronic cardiac failure. It was high in inflammatory, post-embolism and particularly neoplastic effusions. A raised orosomucoid level occurred as the most characteristic of cancer states especially when associated with a parallel increase of the four other glycoproteins. A simultaneously elevated level of these five pleural glycoproteins seems to be a good and significant biological sign for neoplastic effusion diagnosis.

Thirty-nine women admitted to the Main Medical Center for biopsy of a lump in the breast has been followed sequentially for six months to determine whether a diagnostic profile of plasma protein changes occurs in early breast cancer, compared to non malignant breast disease, and whether plasma protein changes in breast cancer patients could be correlated with the spread of the tumor. Eighteen women had early operable breast cancer and twenty-one had benign breast disease. Each patient had 10 serum proteins measured preoperatively and post-operatively at three and six months. The patients with breast cancer had significantly higher levels of beta 2 glycoprotein preoperatively and ceruloplasmin at six months postoperatively than those with benign breast disease. There were a number of significant correlations between serum protein levels and the progression of breast cancer as measured by the clinical score. There were significant correlation with ceruloplasmin properatively and at three months postoperatively. Prealbumin and hemopexin showed correlations preoperatively: alpha 1 antitrypsin and beta 2 glycoprotein only correlated at three months postoperatively. Longer follow up will be required to establish the value of serum protein changes which could predict the development of metastases in patients with breast cancer.

In 92 patients with multiple myeloma and IgG monoclonal proteinemia concentrations of seventeen different serum proteins were specifically determined. Prealbumin, albumin, alpha, HS-glycoprotein, alpha-macroglobulin, transferrin and immunoglobulins IgA, IgM and IgD were significantly decreased in patients with IgG myeloma. On the contrary the means found for the typical acute phase proteins i.e. haptoglobin, orosomucoid and CRP were significantly elevated. No significant differences were demonstrated for less typical acute phase protients, i.e. alpha1-antitrypsin, ceruloplasmin and C3-component as well as for hemopexin and beta2-glycoprotein I. CRP values were strongly elevated in some sera, however in majority of patients they were within the normal limits. Negative correlation was found between monoclonal IgG and the most of the studied proteins inclusive immunoglobulins IgA, IgM and IgD. No correlation was demonstrated between the monoclonal IgG and the triad of typical acute phase proteins. Positive correlation was found between monoclonal IgG and the total serum protein and further among the proteins negatively correlated with monoclonal IgG as well as among the individual acute phase proteins. Explanation of the correlations reported has been suggested.

For detection of plasma proteins produced by human malignant tumors, a survey of blood plasma obtained from nude mice bearing serially transplanted human tumors was performed by immunoelectrophoresis and the double immunodiffusion technique. Among 34 lines including 18 types of human tumors, human specific plasma proteins were demonstrated in the plasma of nude mice transplanted with two lines of renal cell carcinoma, one adenocarcinoma of the colon, and one squamous cell carcinoma of the maxillary sinus. These tumors can be designated as "ectopic" plasma protein-producing tumors since the organs or tissues from which they originated are not considered to be usual sites of plasma protein synthesis. Plasma protein production, as well as that of alpha1-fetoprotein, was also found in one line of hepatoblasotma and three lines of yolk sac tumors. The above tumors were shown to produce one or more of the following 10 of 20 plasma proteins examined: albumin, prealbumin, alpha1-antitrypsin, ceruloplasmin, alpha2-macroglobulin, hemopexin, haptoglobin, C3 and C4 component of complement, and transferrin. An immunochemical demonstration of human specific cancer products observed in human tumors xenotransplanted into nude mice may provide a new approach for investigating the metabolism of neoplastic cells.

A method of numerical classification has been applied to the study of the concentrations of 22 serum antigens in 29 patients with Hodgkin's disease. This group of patients can be split into at least two subgroups. The two subgroups greatly differ by the severity of the clinical symptoms of the disease. One of them is very similar, for the antigen distribution, to a group of presumably normal young subjects. In the other group, there is a definite decrease of the concentration of transferrin, albumin, alpha1 lipoprotein and a definite increase of the concentration of antitrypsin, orosomucoid, ceruloplasmin and hemopexin. This separation into two subgroups is stable when other patients with chronic lymphocytic leukemia are mixed to the patients with Hodgkin's disease.

Fifteen male swimmers (mean age 19.3 +/- 2.1 years) were subjected to a standard 120 min swimming exercise test: a) before, and b) after 5 weeks of intensive training at middle altitude (2000 m). At rest, serum levels of alpha2-macroglobulin, transferrin and copper were elevated in swimmers as compared to untrained subjects. After the altitude training program, significant increases of the parameters of iron and copper metabolism, as well as of alpha2HS-glycoprotein and beta1A-globulin were observed. After the first exercise test (a), a significant rise in serum alpha1-acid glycoprotein, alpha1-antitrypsin, hemopexin, alpha2-macroglobulin, ceruloplasmin, transferrin, iron, copper and alpha2-HS-glycoprotein was noted. The same 120 min-exercise test after the altitude training (b) led to only small changes, especially as concerns the parameters of iron metabolism. The characteristic immediate and long-lasting changes in serum proteins and heavy metals in swimmers and the effects of training in middle altitude on the answer of the organism to swimming exercise with respect to the mentioned biochemical parameters are discussed.

In the serum of 41 children with trisomy 21 (Down syndrome) the concentration was determined of 10 proteins by the radial immunodiffusion method. It was found that the concentration of prealbumin and alpha 2-macroglobulin was lower than in healthy children. The concentration of acid alpha 1-glycoprotein, alpha 1-antitrypsin, haptoglobin, C4 complement component, and hemopexin was higher than in healthy children. The concentration of ceruloplasmin, C3 complement component, and transferrin was similar as in healthy children.

We have developed a modified solvent/detergent (S/D) treatment to inactivate viruses in human plasma using 1% w/w final concentration of tri(n-butyl) phosphate (TNBP) and Triton X-100 and an incubation period of 4 h at 30 degrees C. The procedure inactivates > or = 10(6) chimpanzee-infectious doses (CID50) of HBV, > or = 10(5) CID50 of HCV, and > or = 10(6.2) tissue culture infectious doses (TCID50) of HIV. After virus inactivation, eleven plasma batches were lyophilized and 12 batches were deep-frozen until further use. The batches were characterized by extensive laboratory tests including measurement of clotting factors I-XIII, von Willebrand factor, plasminogen, inhibitors of blood coagulation and fibrinolysis, and other clinically important plasma proteins. All parameters were determined before and after S/D treatment. Twelve conventional single donor plasma units served as control. There were no marked losses of activities of clotting factors, antithrombin III, protein C, plasminogen, and C1-esterase inhibitor due to treatment. After the S/D step, the levels of these parameters were within the normal range in all batches. The same holds true for total protein, immunoglobulins, albumin, complement factors C3 and C4, haptoglobin, hemopexin, caeruloplasmin, alpha 1-antitrypsin, and pH. Protein S and alpha 2-antiplasmin activities decreased by about 50% and were frequently found to be slightly below the lower limit of the respective normal range after treatment. The interindividual variations of all proteins analysed were significantly lower than in the single donor plasma units. The S/D procedure did not lead to increases of markers indicating activation of hemostasis.(ABSTRACT TRUNCATED AT 250 WORDS)
