The acute phase protein response was studied after elective surgery in 13 normal subjects and 9 patients with severe chronic renal failure. Total haemolytic complement reactivity (CH50) and serum concentrations of C1q, C1s, C4, C3, factor B, properdin, C5, C9, C-reactive protein (CRP), caeruloplasmin, alpha1-acid glycoprotein and haptoglobin were measured preoperatively and on days 2, 4 and 6 after operation. Abnormalities were seen in the group with chronic renal failure. Firstly, there was no significant acute phase response of C1s, C3, C5, C9 and CH50 and a significant reduction in the response of factor B. Secondly, CRP showed prolonged elevation in the post-operative period in contrast to the transient rise seen in the control group. With the possible exception of alpha1-acid glycoprotein, the behaviour of the non-complement proteins (caeruloplasmin and haptoglobin) was comparable for the two groups. These defects could impair the physiological response to infection in patients with severe chronic renal failure.

In a series of 100 adult patients with definite rheumatoid arthritis of at most 3 years' duration and with no previous penicillamine, gold or systemic corticosteroid treatment, 50 patients were treated with D-penicillamine and 50 with gold for one yar. The dose of penicillamine was 600 mg daily. Sodium aurothiomalate was given 50 mg weekly up to a total of 13 mg/kg and thereafter 50 mg once a month. In both treatment groups a statistically significant decrease in the number of painful and/or swollen joints, an increase in haemoglobin and a decrease in ESR, serum ceruloplasmin-, alpha1-acid glycoprotein-, IgG-, IgM- and IgA levels was observed. All the changes in these clinical and laboratory tests were of the same degree in both treatment groups. In the penicillamine group 12 out of 20 seropositive patients became seronegative and in another 5 the Waaler-Rose titre dropped clearly. In the gold group, 7 out of 16 seropositive patients became seronegative, and the Waaler-Rose titre dropped in another 5. An equal increase in the number of eroded joints in hands and toes was seen in the penicillamine and the gold group. Penicillamine was discontinued because of side effects in 13 patients (26%), and gold treatment in 15 (30%). Proteinuria and/or haematuria were the most common causes of discontinuation in the penicillamine group.

Histological changes of liver biopsy specimens were compared with functioning liver cell mass estimated by an index, ICG capacity, and with plasma levels of various proteins, in 85 patients with liver diseases. IGC capacity was inversely proportional to the degrees of liver cell degeneration and lymphocyte infiltration in the portal tracts and parenchyma, in contrast to plasma disappearance rate of ICG (K), which was inversely proportional to the degrees of portal tract fibrosis and bridge formation. Among the plasma proteins synthesized in the liver, the plasma levels of prealbumin, and alpha1-acid glycoprotein showed the tendencies to decrease with the increase in the degrees of liver cell degeneration. The levels of ceruloplasmin, haptoglobin beta1A/C and transferrin were proportional to the degree of the degeneration. Plasma albumin had no correlation to any histological change. The plasma levels of gamma-globulin and IgG were both proportional to the degrees of portal tract fibrosis and bridge formation. IgM also paralleled to the degree of the fibrosis. The level of IgA was inversely proportional to the degree of liver cell swelling. It was concluded that quantitative estimations of some histological changes in the liver are valuable for the estimations of liver function and the grade of the diseases of the liver.

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 proliferative diseases of the homeopathic system before starting and at the end of treatment, the values of 8 acute phase factors were studied simultaneously, that is: seromucoid, sialic acid, alpha 1 acid glycoprotein, alpha 1 antitrypsin, haptoglobin, ceruloplasmin, transferrin, and fibrinogen. In chronic myeloid and lymphatic leukaemia no constant increase nor decrease of the concentration of any of the factors was found. In non-Hodgkin lymphoma the concentration of one factor -ceruloplasmin was constantly increased, and that of two factors--sialic acid and fibrinogen was decreased, while in plasmocytoma the concentration of two factors--haptoglobin and ceruloplasmin was constantly increased. At the end of treatment the concentration of certain factors was changing. In chronic myeloid leukaemia the concentration of ceruloplasmin, fibrinogen, and seromucoid was decreasing, while in non-Hodgkin lymphoma the concentration of haptoglobin and fibrinogen was increasing, in chronic lymphatic leukaemia the concentration of haptoglobin and increasing, in chronic lymphatic leukaemia the concentration of haptoglobin and transferrin was increasing, and in plasmocytoma the concentration was increasing of haptoglobin, sialic acid, and transferrin. The result of treatment in chronic myeloid leukaemia was good, in non-Hodgkin lymphoma and chronic lymphatic leukaemia--moderate, and in plasmocytoma it was least beneficial.

The introduction deals with of the history, etiology and, briefly, clinical manifestations of endemic nephropathy. The authors state that a large number of investigations have been done until today, but without producing a diagnostic test for early diagnosis of the disease. This led the authors to pursue certain laboratory investigations. The control group consisted of 30 healthy individuals while patients diagnosed as Endemic Nephropathy were grouped according to stages of the disease: initial, developed, terminal stages. Nucleotides in erythrocytes (5' UMP, 5' IMP, 5' GMP, 5,CMP, 5' AMP, 5' ADP, 5' ATP) were determined on the Acidic Aminoanalyzer, with use of a special UV detector. Catecholamines in the urine were determined by using ratiofluorometery. Creatinine phosphocinase, hydroxybutirat--dehydrogenase and 2,3 DPG were determined on the "Carlbiochem" enzymometer. LDH, its isoenzymes as well as its profile were determined by electrophoresis on starch gel. Specific proteins such as haptoglobin, alpha 2 macroglobulin, alpha 1 antitrypsin, alpha 1 acid glycoprotein, properdin factor B, ceruloplasmin were determined on the Immunochemistry Analyzer. Total cholesterol and cholesterol in lipoproteins fractions VLDL, LDL and HDL were determined on the Cholesterol Analyzer. All results were evaluated statistically. Our conclusion is that they are interesting and contribute to the diagnosis of endemic nephropathy.

Earlier demonstration of elevated blood thyroid hormones and transaminase activities during controlled chamber dives to 540 and 660 msw [at AMTE(PL), Gosport, England; 1980 and 1981] led to the suspicion that high compression may interfere with liver function. Further studies, here described, of blood thyroid hormone level changes during the course of subsequent dives indicate that thyroxine and reverse triiodothyronine elevations are to be expected during any period of sustained compression, to depths as shallow as 61 msw. Moreover, blood levels of thyroxine-binding globulin (TBG), measured in the 540 and 660 msw dives, were also shown to rise, probably accounting for the hormone changes. This elevation is not confined to TBG, being demonstrable in at least six other glycoproteins (sex hormone-binding globulin, transferrin, ceruloplasmin, haptoglobin, alpha 1 acid glycoprotein, and alpha 2 macroglobulin). Since all these proteins share identical or very similar metabolic fates within the liver, these findings lend further weight to our hyperbaric liver dysfunction theory. How such disturbances may come about is discussed, together with its possible implications apropos high pressure nervous syndrome and divers' well-being and capabilities while at depth.

The acute phase proteins (APPs) have been empirically defined as those whose plasma concentration changes following inflammatory reaction. Those proteins whose concentrations increase are referred to as positive APP, while those whose levels decline are termed negative APP. In man, positive APP are: alpha 1 acid glycoprotein, alpha 1 protease inhibitor, alpha 1 antichymotrypsin, haptoglobin, ceruloplasmin, fibrinogen, C-reactive protein, serum amyloid A. Great variability in the APP response between different species is observed. The principal functions of APP, result from the interaction of these proteins with ligands of various origins which give "protein-ligands" complexes. These complexes are cleared by the RES or by the hepatocyte. The results are protease inhibition, neutralization of toxic molecules such as hemoglobin or the superoxide anion, clearance of cell membranes and chromatin. The drop of the plasma concentration of negative APP during an inflammatory reaction carries a rise of free ligands (fatty acids, hormones, vitamins, trace elements). IL6 has been recognized as the principal regulator of most APP genes. The response of the hepatic cell to IL6 is characterized by the enhanced production of type 2 or IL6 specific APPs. The biochemical process of signal transduction is IL6--JAK2--APRF The set of APP genes regulated by IL1 type cytokines (type 1 APPs) is distinct from that regulated by IL6 type cytokine. IL1 and TNF alpha mediated stimulation of type 1 APP genes is synergistically enhanced by IL6 type cytokines. The biochemical process of signal transduction is IL1, IL6--Ras--MAP kinase--NFIL6 The targeted inflammatory proteic profile including the assay of C-reactive protein, haptoglobin and alpha 1 acid glycoprotein produces a "biological tool" to the clinician in order to manage an inflammatory response. IL6, a proteic marker for the future, connected with CRP, will be assayed during early inflammatory reaction.

In our recent project of establishing reference intervals for 13 plasma proteins following the NCCLS proposed guideline (C28-P, 1992), confounding and interacting relationships were found among criteria for partitioning reference individuals. Therefore, we found it necessary to test for the validity of the criterion by multivariate analysis so that such relationships could be revealed. Meanwhile, to find difference appropriate for the partition, sex- and age-related differences were examined in common screening tests whose reference intervals (RI) were conventionally set for each subgroup. The result led to our standard for partitioning when the difference between subgroups exceed 10% of the span of a RI derived without partitioning. Among the 13 plasma proteins, the multivariate analyses and the standard indicated gender-based RI was for IgM, alpha 1 acid glycoprotein, alpha 2 macroglobulin, and transferrin, transthyretin. None of the age-related differences were large enough. In serum IgM, ceruloplasmin, and transferrin, however, females tended to have larger differences between ages, exemplifying interaction of gender on age-related changes of the analytes. Smoking-related differences were > 10% in IgG and transthyretin. However, differences in the latter proved to be spurious multivariately. These results suggest a necessity for additional descriptions on the validity of the partitioning criterion in the NCCLS proposed guideline.

Several chromatographic methods have been developed for the isolation and characterization of glycoproteins. In these methods, affinity chromatography, a single-step method, or combined use with general chromatographic methods have now become essential for the purification of many biologically important glycoproteins, including alpha1-acid glycoprotein, immunoglobulins, ceruloplasmin and erythropoietin. On the other hand, almost all glycoproteins exhibit polymorphism associated with their glycan moieties. This feature is wide-spread and has been observed in natural as well as in recombinant DNA glycoproteins. Recently, several sophisticated techniques--such as electromigration method (high-performance capillary electrophoresis) and chromatographic methods (two-dimensional polyacrylamide gel electrophoresis, high-pH anion-exchange chromatography with pulsed-amperometric detection)--have been introduced for qualitative or quantitative estimation of the microheterogeneity of glycoproteins. For gaining further insight into the structure-function relations for microheterogeneity, preparative chromatographic techniques that can yield sufficient quantities of glycoprotein variants must be developed.
