The level of ceruloplasmin in plasma was measured as polyphenol oxidase activity in following groups of rats: 1. controls; 2. adrenalectomized; 3. shamadrenalectomized; 4. formalin arthritis; 5. ACTH treated (25 micrograms ACTH daily for 5 days); 6. adrenalectomized and ACTH treated (as in a previous group). The level of ceruloplasmin was markedly increased after formalin arthritis, after ACTH treatment in controls and in adrenalectomized animals.

Serum levels of carrier proteins, transferrin, ceruloplasmin and albumin were determined in patients with rheumatic disorders, along with serum levels of acute phase proteins, ceruloplasmin, alpha 1-acid glycoprotein and alpha 1-antitrypsin. Depressed levels of transferrin occurred in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Albumin was reduced in SLE and RA men. Acute phase reactants which are protective in inflammation were elevated in RA, osteoarthritis (OA), gout, pseudogout (PsG), and SLE. All of these rheumatic disorders show biochemical changes compatible with systemic inflammatory disease including gout and PsG which are considered local disorders and OA which is considered noninflammatory arthritis.

Sera and synovial fluid were investigated in 45 patients with rheumatoid Arthritis and 50 patients with osteoarthritis in inflammatory exacerbation (control group). The following tests were performed: IgG, IgM, IgA determinations, complement components C3, C3, C4, C3-proactivator, ceruloplasmin, electrophoresis, LDH and total acid phosphatase. 1. Serum levels of the ceruloplasmin, alpha 1, alpha 2 and gamma fractions of electrophoresis are significantly higher in patients with rheumatoid arthritis than in patients with osteoarthritis. 2. Synovial fluid: a) There is a significantly higher concentration of IgG, IgM, IgA, C3-proactivator and total acid phosphatase in the synovial fluid of patients with rheumatoid arthritis. b) C4 is significantly lower in patients with rheumatoid arthritis. c) Both groups were also compared with the help of a point system. Every patient received a plus point when the following criteria were seen: IgM greater than 150 mg/100 ml, C3 greater than 50 mg/100 ml, ceruloplasmin greater than 35 mg/100 ml, alpha 1 greater than 0.21 g%, alpha 2 greater than 0.44 g%, beta greater than 0.60 g% and gamma fraction on electrophoresis greater than 0.90 g%. Another point was added if the criteria ceruloplasmin greater than 22 mg/100 ml and C4 less than 17 mg/100 ml were simultaneously seen. With the help of this points system 48 out of the 50 osteoarthritis patients (96%) received zero points, one received 1 point and one 2 points, as opposed to the patients with rheumatoid arthritis where 35 out of 45 (78%) received one or more points. d) The differentation is not improved through additional testing of the rheumatic factors.

Changes in lipid peroxidation parameters (LP), antioxidant system and proteinase inhibitors were studied at different evolutionary stages of experimental osteoarticular tuberculosis in 30 rabbits. All stages of the process were characterized by LP activation which in animals of all groups (except rabbits having the acute stage of arthritis) is accompanied by compensatory increase of superoxide dismutase and ceruloplasmin activity. Deficiency of superoxide dismutase found in the acute stage of arthritis with a growth of LP activity shows its inadequate production at a given stage of articular inflammation. Decrease in alpha 1-proteinase inhibitor activity at the stage of osteitis with reactive synovitis can be caused by the influence of LP products. The importance of this mechanism in the inhibition of alpha 1-proteinase inhibitor, together with reduction in its production at the acute stage of arthritis, cannot be ignored. The results obtained make it possible to recommend further study of the perspectives of antioxidants use in osteoarticular tuberculosis.

Two phases of arthritis, acute phase (four days after adjuvant inoculation) and chronic phase (21 or 29 days after adjuvant inoculation) were studied in male rats. The effect of administration of vitamin C in a daily oral dose of 50 mg/kg body wt for four and 21 days starting on the day of adjuvant inoculation and for 7 days starting 21 days after adjuvant inoculation against these phases of arthritis was demonstrated. Results showed that prolonged administration of vitamin C (21 days) increased the lowered serum sulphydryl (SH-groups) to prearthritic values while it decreased the elevated level of blood glutathione (GSH) of arthritic rats. However, neither (four-day) nor seven-day treatment with vitamin C exerted any significant changes in these parameters. The results showed also a slight significant increase in the level of erythrocyte superoxide dismutase activity (SOD) [1.15.1.1] upon seven-day treatment with vitamin C. Meanwhile, four-, 21- or seven-day treatment with vitamin C produced no significant change in the elevated levels of serum ceruloplasmin (Cp) and alpha 2-macroglobulin (alpha 2-M) of arthritic rats. However, 21-day and 7-day administration of vitamin C has improved the lowered A/G ratio in these animals. The improvement in these parameters after prolonged administration of vitamin C was explained in the light of the antioxidant property of this vitamin and suggests a beneficial role for it in the treatment of arthritis.

The efficacy of a drug containing three heavy metals together has been tested in adjuvant-induced arthritic rats. Treated rats were injected with 22.8 micrograms copper gluconate, 0.2 microgram gold thioglucose and 6.8 micrograms silver proteinate each day during a period of 29 days. The drug treatment was found to diminish the increases in plasma levels of haptoglobin, ceruloplasmin, PGE2, 6-keto-PGF1 alpha and copper, the decrease in the iron plasma level induced by Freund's adjuvant and the paw swelling. No effect was seen on the plasma levels of TXB2, Zn, Se, Mn and Ni. Therefore the simultaneous administration of low doses of gold, copper and silver had a real anti-rheumatic property in this model. These results should be of interest for the long-term treatment of arthritis.

Methods are described for the quantification of certain acute phase reactants (albumin, iron, fibrinogen, seromucoid, haptoglobin, and ceruloplasmin) in small amounts of plasma using the COBAS-BIO centrifugal analyzer. These methods have been applied to determine the concentrations of these acute-phase reactants (APRs) in rat plasma during the first 5 days of adjuvant-induced arthritis. The levels of the APRs alter with the degree of inflammation in a dose-related manner. Administration of the antiinflammatory and antirheumatic drugs (indomethacin, dexamethasone, and clobuzarit [CLOZIC]) during the course of the adjuvant-induced arthritis reduced the inflammatory response as judged by the measurement of oedema. These compounds, however, show differential effects on the profile of APRs as systemic measurements of the inflammatory disease. The present study shows that specific classes of drug have defined effects on acute-phase protein concentration. We believe that the multiple analysis of APR levels during the course of inflammation may help to distinguish between and elucidate the mechanisms of action, of antiinflammatory and antirheumatic drugs.

Trace elements such as zinc, copper and selenium are involved in the pathogenesis of inflammatory diseases. In order to obtain more information about the overall movements of these minerals during the evolution of an experimental chronic inflammatory process, trace element levels were determined in five body compartments of the rat at several time intervals after induction of adjuvant arthritis. Rapid and significant changes in plasma zinc and copper levels and in liver zinc levels were observed. These modifications occurred as early as those in biochemical parameters of inflammation such as serum fibrinogen and ceruloplasmin, and preceded the appearance of any clinical symptom of the disease. Inverse correlations were found between plasma zinc levels and these two biochemical indices. Other modifications in trace element levels were observed two weeks after disease induction, the most important being a considerable increase in liver copper levels. Although food intake of affected animals decreased with the progression of the disease, there was no evidence of depletion in zinc and copper levels over the study period. A redistribution of body zinc between different biological compartments (mainly plasma and liver) occurred simultaneously with an accumulation of copper in several organs. The decreasing selenium status of animals was not clearly related to the inflammatory process.

The induction of ceruloplasmin and metallothionein was investigated in rats with the early inflammatory phase of adjuvant arthritis. When examined at the peak of the acute inflammatory response, 5 days after adjuvant treatment, zinc given daily (2 mg/kg, intraperitoneally) increased serum ceruloplasmin levels by 2.0 times that found in nonarthritic rats and 1.2 times that found in non-zinc-treated arthritic rats. 13-cis-Retinoic acid (160 mg/kg, orally) given daily increased serum ceruloplasmin 2.2 and 2.7 times that found in nontreated arthritic rats when given alone and with zinc (2 mg/kg, intraperitoneally), respectively. Reduction in the inflammatory response was measured by weight of the adjuvant-injected paw, 5 days after adjuvant was administered. The reduction in inflammation was 13 and 19-20% for 13-cis-retinoic acid and zinc, respectively, when given alone, and between 26 and 31% when the treatments were combined. Zinc markedly increased liver metallothionein levels whereas 13-cis-retinoic acid was a much less potent inducer of the protein in liver. The results are discussed in light of the probable physiological roles of both ceruloplasmin and metallothionein.

Mianserin protein binding was measured in serum from 43 healthy subjects and plasma from 12 elderly depressed patients and 23 patients with rheumatoid arthritis. Free fraction (mean +/- SD) was 5.5 +/- 0.7% in the healthy subjects, 5.0 +/- 0.8% in the elderly subjects and 6.0 +/- 1.0 in the patients with rheumatoid arthritis. In the group of elderly patients treated with mianserin, a high correlation (r = 0.83, P less than 0.001) between total and free concentrations of mianserin was found. In both groups a high linear correlation (r = +0.90, P less than 0.001) between the free fraction of mianserin and that of imipramine was found, the latter being about twice as high as for mianserin. In both healthy subjects and arthritis patients the degree of protein binding was positively correlated to the concentration of alpha 1-acid-glycoprotein and complement C3c, and somewhat more weakly to haptoglobin. In the healthy subjects protein binding was also highly positively correlated to the concentration of apolipoprotein B, whereas no such correlation was found in the rheumatoid arthritis patients. In the rheumatoid arthritis patients protein binding was highly correlated to the concentration of hemopexin and somewhat more weakly to ceruloplasmin and fibrinogen; a weak negative correlation to the concentration of albumin was also found. Since significant intercorrelations between the concentrations of these proteins were found, the correlation to the degree of binding of mianserin may not necessarily represent binding of the drug to the protein.
