Electrophoreses of sera, plasma and ascitic fluids of cats with natural or experimental infectious peritonitis show important modifications. Special stainings of electrophoreses and chromatographic and immunoelectrophoretic technics characterized some of the modified proteins. In the experimental disease, fibrinogen, haptoglobin, transferrin, and probably orosomucoid are increased; in the natural disease, in addition to these modifications, the gamma-globulins are strongly increased; the immunoglobulins found in the often abundant ascitic fluid belong to the IgG class. Increased proteins such as fibrinogen, haptoglobin and orosomucoid and decreased albumin are aspecific aspects of inflammatory processes, whereas hypergammaglobulinemia appears in the course of immunological response. The rapid evolution of the experimental disease explains the fact that immunoglobulins do not increase.

Five glycoproteins have been measured in the blood of 145 diabetic patients with and without clinical evidence of complications. Patients with diabetic complications have higher glycoproteins levels particularly when expressed as a ratio to serum albumin levels. In 32 pairs of patients matched for age, sex, body weight, duration and treatment of diabetes, significantly higher haptoglobin, fibrinogen and caeruloplasmin levels were associated with the presence of diabetic complications, but blood glucose levels were not significantly different. Beta-lipoprotein levels were positively correlated with age and alpha2-macroglobulin levels with the duration of clinical disease, but the type of antidiabetic therapy administered did not significantly alter glycoprotein levels. It is suggested that rising levels of certain glycoproteins in the blood of diabetic patients may indicate the development of diabetic vascular complications, but a prospective study is required before it can be decided whether this change predates the clinical appearance of the complications.

The isolated rat liver perfused for 12 hours at pH 7.10 with a suspension of bovine erythrocytes in Krebs-Ringer bicarbonate buffer containing 3 per cent bovine serum albumin has been used as a test system to study effects of glucagon and of dexamethasone in the presence and absence of insulin on net biosynthesis of rat serum albumin, fibrinogen, alpah1-acid glycoprotein, alpha2-(acute phase) globulin, and haptoglobin. Quantitative measurement of perfusate glucose, amino acid nitrogen, and urea affords a basis for determining net glucose and nitrogen balance in the perfusion system. Although the dose of dexamethasone (total 1.0 mug.) used was insufficient to induce synthesis of alpha2-acute phase globulin, net syntheses of albumin, fibrogen, alpha1-acid glycoprotein, and haptoglobin were increased. Glucagon given with dexamethasone depressed albumin and haptoglobin synthesis markedly, but not that of fibrinogen and alpha1-acid glycoprotein. Glucagon with dexamethasone markedly enhanced ureogenesis and glycogenolysis and elicited an exaggerated negative nitrogen balance. The unfavorable effects of glucagon on albumin and haptoglobin synthesis and on nitrogen balance were reversed by giving insulin simultaneously. It is emphasized that insulin is essential for positive nitrogen balance.

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.

Comparison of the electrophoretograms of normal canine plasma and serum revealed a greater concentration of the beta3-fraction in plasma due to the presence of fibrinogen. When serum or plasma of hemolyzed canine blood was analyzed electrophoretically, there were slurring of the beta-globulin peaks due to the presence of free hemoglobin and increases in alpha2-globulins due to the formation of the haptoglobin-hemoglobin complex.

In 14 patients with acute myocardial infarction (M.I.) not having any other disease, the possible quantitative relationship between enzymes from M.I. and changes in concentration of acute phase reactants coming from the liver were studied. The patients were followed up until 1 1/2 years after M.I. and comparison of baseline-protein values took place using a control group of 18 healthy individuals. Quantitation of protein changes was done by planimetric determination of the area under the concentration curve and by taking peak values. The myocardial infarction was quantitatively estimated by mathematical analysis of the time course of alpha-hydroxybutyrate dehydrogenase (alpha-HBDH) plasma concentrations and by taking peak values. A quantitative relationship with enzymatic infarct size was found for haptoglobin, alpha1-acid glycoprotein, alpha1-antitrypsin, C-reactive protein, fibrinogen and E.S.R. Albumin and transferrin did not show a negative quantitative relationship with enzymatic infarct size. Humoral factors originating from the site of tissue injury and evoking in proportion a positive acute phase reaction by the liver are probably the basis for this observed quantitative relationship.

A total of 31 strains of oral streptococci representing Streptococcus mutans, Streptococcus sanguis, Streptococcus mitior, Streptococcus salivarius, and Streptococcus milleri were tested for possible binding of human immunoglobulins G, G1, G2, G3, G4, A1, A2, M1, and M2 and haptoglobin, hemoglobin, fibrinogen, and aggregated beta 2-microglobulin. Radiolabeled beta 2-microglobulin in aggregated form showed affinity for 20 of the 31 strains tested. Binding activity for the protein was found in strains belonging to all five species. The bacterial receptor was resistant to trypsin. Monomeric, unlabeled beta 2-microglobulin did not interfere with the binding of the aggregated form. Of the other proteins tested, only the immunoglobulin A1 protein showed positive binding, and that was only with a single strain of S. milleri. beta 2-Microglobulin is present on all nucleated cell membranes in vivo. The reaction between aggregated beta 2-microglobulin and oral streptococci is a new type of human-bacterium interaction which should be considered in studies of bacterial adherence.

Bacterial endotoxin injected into rats resulted in increased plasma concentration of alpha 2 macroglobulin, haptoglobin and fibrinogen. Cortisone acetate injected i.m. by itself was sufficient to increase the plasma concentration of haptoglobin by 54% and to a lesser extent the concentrations of the other two proteins. When cortisone acetate and/or cortisol succinate were injected simultaneously with varying doses of endotoxin, the effects of the corticosteroid differed for each plasma protein. Doubtless because of the effect of cortisone by itself the slope of the dose-response relationship for haptoglobin was greatly reduced. In contrast to this the slope for alpha 2 macroglobulin was reduced and that for fibrinogen was unaffected. These findings suggest that, if effects due to endogenous corticosteroids are to be avoided, increases in plasma fibrinogen will serve best as indicators of stimulation of the acute-phase response. Since, however, the relative increase of alpha 2 macroglobulin due to the lowest dose of endotoxin was much greater than that of fibrinogen, increases in concentration of the former protein represent the most sensitive indication of the acute-phase response. Consideration of the responses in individual rats has made possible division into those with more or less than average increases for all 3 plasma proteins and those showing irregular responses. Especially in the group which had received the lowest dose of endotoxin, a much larger number than would be expected on a random basis was found to respond regularly with either more or less than average increases for all 3 proteins.

"Buffy-coat" residues from human blood have been investigated as a source of leucocytic endogenous mediator (LEM). After separation from most of the erythrocytes and uptake of opsonized zymosan by the polymorphonuclear leucocytes (PML) and macrophages, the cells were incubated in Hanks' medium. To demonstrate the presence of LEM the supernatant thus produced was injected into rats and then after 24 h increases in the plasma concentrations of haptoglobin, alpha 2 macroglobulin and fibrinogen were estimated. For comparison rats were also injected with LEM prepared from rabbit peritoneal cells. Because these cells were obtained from rabbits which had been stimulated by i.p. injection of glycogen, addition of zymosan in vitro was not required. Despite the different species from which the leucocytes were obtained and the different method of preparation of LEM, similar increases in concentration of haptoglobin, fibrinogen and alpha 2 macroglobulin in the plasma of the recipient rats were obtained. Because injection of LEM resulted in very varied increases in concentration of each of the 3 plasma proteins, an attempt was made to ascertain whether positive responses for all 3 proteins occurred in the same rats or whether the rats responded randomly. The presence of endogenous pyrogen as a constituent of the LEM produced from both sources was confirmed using both rabbits and prewarmed mice (Bodel and Miller, 1976).

Alpha 2 macroglobulin, haptoglobin and fibrinogen plasma levels were simultaneously determined, as well as E.S.R., to test if a significant difference could be found among cancer, inflammatory diseases and control subjects. Haptoglobin was higher in the cancer group and fibrinogen in inflammatory diseases, but these selective increases are not believed to be enough to suggest the widespread determinations of these proteins. A significant correlation was found between alpha 2 macroglobulin and E.S.R., as well as between fibrinogen and E.S.R.
