Four acute phase proteins were assayed in the serum of normal horses and those with acute, subacute and chronic grass sickness, colic and inflammatory conditions, in order to investigate their diagnostic value in grass sickness. The grass sickness and inflammation group had a significantly increased haptoglobin concentration (P less than 0.01-P less than 0.001). Orosomucoid was elevated in acute, subacute and chronic grass sickness and inflammation (P less than 0.001, P less than 0.001, P less than 0.05 and P less than 0.05, respectively). Highest concentrations of haptoglobin and orosomucoid were recorded in subacute grass sickness. Ceruloplasmin was significantly higher in acute grass sickness cases than all other groups except the colic group (P less than 0.05-P less than 0.01). alpha 2-macroglobulin was significantly higher in acute grass sickness than normal, colic and chronic grass sickness cases (P less than 0.01, P less than 0.05 and P less than 0.05). The time scale of changes suggests that the stimulus to haptoglobin and orosomucoid synthesis occurs at the onset of clinical signs whereas the increase in ceruloplasmin and alpha 2-macroglobulin is more likely to reflect haemoconcentration.

Based on the findings that the enhancement of serum alpha 2-macroglobulin (A2M) is associated with the occurrence of infectious complications following surgery in patients with esophageal cancer, we examined possible factors which could contribute to the alterations of serum acute phase protein levels in patients with this disease. A multiple linear regression analysis was made for 71 patients with esophageal cancer and 58 with gastric cancer. In patients with esophageal cancer, protein calorie malnutrition (PCM) and age factors more strongly contributed to the alteration of 6 acute phase protein levels than did the malignant tumor when compared to those with gastric acner. PCM was negatively associated with A2M levels while it was positively associated with alpha 1-acidglycoprotein (A1AG) and haptoglobin (Hp) levels. Age did not contribute to the A2M levels but did have a negative effect on the Hp, ceruloplasmin (Cp) and fibronectin (Fn) levels. On the other hand, the malignant tumor was positively related only to the A1AG levels. Since none of these factors contributed to the elevation of A2M levels, it is suggested that the presence of chronic infection might be a factor contributing to the A2M increase which was associated with the occurrence of postoperative infectious complications in patients with this disease.

Severe septic complications are the major cause of operative mortality in patients with esophageal cancer. We examined the levels of acute phase proteins together with infection-related complications after surgery in a large number of patients with esophageal cancer and compared them with a group of patients with gastric cancer and healthy controls. Elevations in alpha 1-antitrypsin, alpha 1-acidglycoprotein, haptoglobin and ceruloplasmin were evident in patients with esophageal cancer, being more predominant when compared to the findings in patients with gastric cancer. Although the mean levels of alpha 2-macroglobulin were not significantly elevated in either patients with esophageal cancer or those with gastric cancer, the average level immediately prior to surgery was higher in esophageal cancer patients with postoperative septic complications than in those without any such problems. Preoperative radiation therapy and total parenteral nutrition did not significantly alter the levels of acute phase proteins. It would thus appear that the elevation in alpha 2-macroglobulin is associated with the occurrence of infectious complications following surgery in patients with esophageal cancer.

The study was carried out in 89 men aged 21 to 57 years with a history of exposure to mercury vapour from 2 to 26 years during occupational work involving chlorine production by the method of mercury electrolysis. The workers were divided into three groups depending on the duration of occupational exposure: 1) 32 workers with a short history of exposure 2-10 years, 2) 37 workers with medium-long exposure - 11-20 years, and 3) 20 workers with a history of long exposure - 21-26 years. The urinary concentrations of mercury in these individuals was 73 +/- 60 microliters x 1(-1), and in blood this concentration was not exceeding 50 microliters x 1(-1). The control group comprised 40 men aged 17 to 52 years. They had not had any occupational exposure to chemicals, or harmful physical factors. On the basis of clinical, haematological and biochemical studies 89 workers with occupational exposure to mercury vapour were regarded as clinically healthy. None of them had any symptoms and signs of the complete neurasthenic syndrome or organic brain injury. Increased nervous excitability was the complaint of 24 workers, 9 had headaches, sleep disturbances were reported by 5, and a feeling of tiredness and apathy was mentioned by 5 men. EEG recording demonstrated 81 normal tracings, and moderately pathological records in 8 men. The parameters of immunity and proteins acute phase reaction were determined, measuring the concentration of immunoglobulins, lysozyme, C3c, C4, alpha 1-acid glycoprotein, haptoglobin and ceruloplasmin in serum. A lower level of IgA, IgG and lysozyme was only noted in individuals with occupational exposure exceeding 20 years.(ABSTRACT TRUNCATED AT 250 WORDS)

In various anaemias the values of 8 acute phase factors were determined simultaneously before and at the end of treatment: seromucoid, sialic acid, acid alpha 1-glycoprotein, alpha 1-antitrypsin, haptoglobin, ceruloplasmin, transferrin and fibrinogen. In iron-deficiency anaemia without coexistent inflammatory changes in organs the levels of 4 proteins--seromucoid, alpha 1-antitrypsin, ceruloplasmin and transferrin, were consistently raised. In iron-deficiency anemia with concomitant infection 4 proteins also were increased, but in place of alpha 1-antitrypsin the haptoglobin level was raised. In megaloblastic anaemia the ceruloplasmin level was increased, and in haemolytic anaemia one factor--sialic acid--was decreased. At the end of treatment the concentrations of certain proteins were changed depending on their specific role in various forms of anaemia and on various additional factors. In iron-deficiency anaemia without coexistent infection the concentration of seromucoid was decreased, and in this anaemia with coexistent infection alpha 1-antitrypsin, haptoglobin, and fibrinogen levels were raised, in haemolytic anaemia only fibrinogen was increased, and megaloblastic anaemia was associated with raised seromucoid level. The therapeutic result was good in all these anaemias with the exception of iron-deficiency anaemia associated with infection in which it was less propitious.

The body's protective responses to infection, wounding, trauma, and malignancy include the acute-phase reaction, which is modulated by various cytokines and their cellular receptors. During the acute-phase reaction, levels of specific proteins synthesized by the liver increase in the plasma. Little information is available about the extrahepatic synthesis of plasma proteins during the acute-phase reaction. The study described here analyzes the tissue-specific expression of genes encoding the plasma proteins albumin (ALB), alpha 1-antitrypsin (AAT), transferrin (TF), haptoglobin (HP), ceruloplasmin (CP), serum amyloid A (SAA), alpha 1-acid glycoprotein (AGP) and alpha 2-HS-glycoprotein (AHSG) during the acute-phase reaction in C57B1 mice. The acute-phase reaction was induced by intraperitoneal injections of bacterial lipopolysaccharide (LPS). During the acute-phase reaction, genes encoding CP, SAA, AGP, and HP demonstrate unique extrahepatic tissue specific patterns of expression in kidney, spleen, thymus, heart, brain, lung, testis, and epididymis. Different temporal patterns of HP gene expression also were observed in lung and thymus after induction by LPS. The function of extrahepatic synthesis of plasma proteins is not yet understood; however, a local provision of specific plasma proteins in mammalian tissues may offer the host a source of functionally important proteins during periods of stress.

Assay procedures for determining serum haptoglobin concentration and ceruloplasmin oxidase activity in dogs were validated, and reference values were established. Serum haptoglobin concentration is reported as milligrams per deciliter of cyanmethemoglobin binding capacity, whereas serum ceruloplasmin oxidase activity was determined by use of p-phenylenediamine as substrate. Both assays were used to analyze serum samples from 288 dogs. In each dog's case record, clinical history and final diagnosis were evaluated to determine whether the dog had an inflammatory condition. Complete blood cell counts were performed in 265 dogs, using simultaneously collected blood samples. Plasma fibrinogen concentration was determined for 161 dogs. A positive correlation (P less than 0.01) for serum haptoglobin concentration and for ceruloplasmin oxidase activity, compared with WBC counts, segmented neutrophil and band neutrophil counts, and plasma fibrinogen concentration. Ceruloplasmin oxidase activity and haptoglobin concentration were up to 6 times more sensitive than fibrinogen concentration or leukocyte counts in detecting inflammation. Specificity of ceruloplasmin oxidase activity was comparable to fibrinogen concentration and leukocyte counts, whereas haptoglobin concentration was found to be slightly less specific. Specificity of haptoglobin concentration improved slightly (from 0.82 to 0.88) when dogs with a history of glucocorticoid administration were excluded from analysis. Predictive value of a negative test result (haptoglobin concentration less than 125 mg/dl; ceruloplasmin oxidase activity less than 20 IU/L) and predictive value of a positive test result for haptoglobin concentration and ceruloplasmin activity were comparable to or better than fibrinogen concentration or various oxidase leukocyte counts in detection of inflammation in a variety of disease conditions.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

Phenotypes of haptoglobin (Hp), group-specific proteins (Gc), transferrins and ceruloplasmin were studied by means of polyacrylamide gel disk electrophoresis of serum proteins in 411 tuberculosis patients and 283 apparently healthy individuals living in the North-West and Extreme North. Regardless of their ethnic affiliation, tuberculosis patients tend to accumulate Hp 2-2, Gc 1-1 carriers and Hp 2-2 + Gc 1-1 combinations. The persons with the above types of individual proteins usually have a serious clinical picture of the disease and lower activity of the immune T-system, as confirmed by different methods of multidimensional statistical analysis. Hp 2-2, Gc 1-1 carriers and Hp 2-2 and Gc 1-1 combinations among the Extreme North's healthy aboriginal population are more widespread than among the healthy inhabitants of the North-West.

Human interleukin 6 (IL-6) produced by molecular cloning was administered to nonhuman primates to assess its biological activities in vivo. Rhesus monkeys were treated s.c. with recombinant human (rh) IL-6 at 3 and 30 micrograms/kg body weight/day for 11 days, followed by the administration of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) at 5.5 micrograms/kg/day for 5 days. Serum levels of positively regulated acute phase proteins (APP) (C-reactive protein, alpha 1-antitrypsin, haptoglobin, and ceruloplasmin) increased, whereas negatively regulated APP (prealbumin) decreased in response to rhIL-6 treatment in a dose-dependent manner. Platelet counts rose after a latent period of 4-5 days following the start of rhIL-6 treatment, resulting in a maximum twofold increase above normal levels 2-3 days after the termination of the rhIL-6 treatment. Recombinant human IL-6 treatment induced a two to threefold rise in myeloid progenitor blood cell levels. The subsequent administration of rhGM-CSF to rhIL-6-pretreated animals did not increase the progenitor cell levels in blood above those found with rhGM-CSF treatment alone, indicating that rhIL-6 compared to recombinant human interleukin 3 (rhIL-3) has a minor proliferative effect on hematopoietic precursors in vivo. In conclusion, rhIL-6 was shown to be a potent stimulator of APP and was able to increase the number of platelets in circulation in nonhuman primates.
