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.

In a sample group of 92 women undergoing prenatal echo-guided transabdominal amniocentesis between the 12th and 23rd week of pregnancy the Authors analysed amniotic fluid and maternal serum using the recently developed method of high resolution protein electrophoresis in order to identify the presence of particular proteins in the amniotic fluid which are pathognomonic for a number of maternofetal pathologies. The results obtained in normal and pathological pregnancies or in the case of twins showed a marked dispersion in amniotic fluid of total protein concentrations depending on the period of gestation; in addition, albumin, alpha 1-antitrypsin, alpha 2-glycoprotein acid, alpha 2-macroglobulin and beta 2-protein were also found. Plasma levels of prealbumin, albumin, alpha 1-glycoprotein acid and IgG were slightly reduced, whereas there was a marked increase in ceruloplasmin, transferrin and fibrinogen; C3 and haptoglobin levels were normal. It is therefore possible to ascertain that amniotic fluid proteins analysed by high-resolution 15-band electrophoresis did not vary qualitatively or quantitatively until the 23rd week of gestation and in those cases of twin or pathological pregnancies examined no anomalous band was found in the protein electrophoresis of maternal serum or amniotic fluid which might prove useful in prenatal diagnosis.

It has been reported that microheterogeneity (M-HT) of serum glycoproteins including transferrin is found in alcoholic liver disease (ALD). In the present study, M-HT of serum glycoproteins in ALD patients was analyzed using the Western blotting technique after isoelectric focusing. M-HT was found in serum alpha 1-antitrypsin, alpha 2-macroglobulin, ceruloplasmin, alpha 1-acid glycoprotein and hemopexin as well as transferrin, but not in serum prealbumin. M-HT disappeared following treatment with sialidase in one group of glycoproteins, but not in another group of glycoproteins. In hemopexin, M-HT was recognized only after treatment with sialidase. These results suggest that mechanisms of the appearance of M-HT of serum glycoproteins in ALD may differ. One mechanism is the interference of glycosylation of glycoproteins in the Golgi apparatus, and another is the decrease of asialo-protein receptors in hepatocytes.

Eleven proteins (immunoglobulins IgG, IgA, IgM, orosomucoid, alpha 1-antiproteinase, haptoglobin, ceruloplasmin, C-reactive protein, transferrin, prealbumin and alpha 2-macroglobulin) in human serum were quantitated by a new microparticle-enhanced nephelometric immunoassay. This is a one step competitive assay, based on the nephelometric measurement of light scattered by clusters of protein-coated microparticles specially synthesized for that use. Statistical evaluation (precision, recovery and method comparison) shows that the determination of serum proteins is reliable and accurate for wide ranges of concentration and that the method is quite adequate for strongly increased concentrations. This microparticle-enhanced nephelometric immunoassay appears to offer an alternative method for routine measurement of a great variety of serum proteins at high and intermediate concentrations, which are usually quantified by radial immunodiffusion or conventional immunonephelometry. On account of its sensitivity, it can also be used for the determination of relatively low concentrations of analytes.

To determine the ability of intraoperative hypothermia to modify changes in the plasma protein component of the acute-phase response (APR) and the plasma hormone component of the endocrine response (ER) to surgical injury, 20 patients undergoing coronary artery surgery were randomised to an intraoperative blood temperature of 28 degrees C or 20 degrees C during cardiopulmonary bypass (CPB). Serial measurements of pack-cell-volume corrected concentrations (PCVCC) of five plasma proteins (albumin, prealbumin, transferrin, caeruloplasmin, ferritin) and six plasma hormones (adrenaline, noradrenaline, cortisol, triiodothyronine, thyroxine, and thyroid-stimulating hormone) were obtained twice preoperatively, seven times during surgery, six times in the 24 hours following surgery, and a further four times until the seventh postoperative day. A more profound level of intraoperative hypothermia significantly reduced the plasma adrenaline response to CPB but not the other components of the ER or APR.

In 24 patients with terminal renal failure the concentrations were determined of beta 2-microglobulin, prealbumin, alpha 1-antitrypsin, ceruloplasmin, alpha 2-macroglobulin, antithrombin III, plasminogen, transferrin, C3c and Cr complement components in the serum before and after haemodialysis. A statistically significant rise of concentrations of these proteins was found. It is thought that this rise was due mainly to haemoconcentration, while the contact with dialysing membranes is less important.

The authors investigated within the framework of non-specific immunity reactions proteins of the acute phase during spontaneous delivery and Caesarean section up to the 5th day after delivery and on the 1st, 5th and 10th day after delivery in forty women, half of them healthy and half suffering from late gestoses. Half the women had spontaneous deliveries, half had deliveries by Caesarean section. The proteins of the acute phase reacted sensitively to the stress of childbirth during spontaneous delivery and their activation was inhibited by general anaesthesia in deliveries by Caesarean section. After spontaneous delivery the elevated proteins of the acute phase returned to baseline values by the 5th day, after operation their levels rose further up to the 5th day, orosomucoid to the 10th day after operation. In late gestoses with spontaneous delivery or by Caesarean section there were significantly elevated alpha-1-antitrypsin and alpha-2-macroglobulin and orosomucoid levels, whole in patients with late gestoses in the prealbumin levels were reduced. The elevated levels of proteinase inhibitors in late gestoses support the view on a possibly impaired coagulation equilibrium in late gestoses, and the high ceruloplasmin levels suggest an enhanced catecholamine breakdown during the stress alarm reaction.

Total protein, alphafetoprotein, albumin, prealbumin, alpha-1-antitrypsin, transferrin and ceruloplasmin levels were measured in samples of human fetal and neonatal cerebrospinal fluid (CSF) (97 cases), obtained between 12 and 41 weeks of gestation. In 39 of these cases (13 to 40 weeks gestation) plasma was also available for comparative analysis. CSF was collected from lateral ventricles in the first half of gestation and from the lumbar region in the second. Since these CSF samples were obtained from different sites, the protein levels in the lateral ventricle (early) samples could not be compared directly with those in the lumbar (later) samples. However, the mean protein levels in the lumbar samples were lower than those in the ventricular samples, which is in accord with the decline in CSF protein levels described in maturing animal fetuses. Despite a wide scatter of results, particularly in the first half of gestation, significant decline in the level of CSF alphafetoprotein was demonstrated during both first and second halves of gestation, and of albumin and prealbumin in the second half. No sex differences were found except for ceruloplasmin in lumbar CSF later in gestation, when males had higher levels than females. In fetal plasma, protein levels increased with increasing gestation apart from alphafetoprotein and prealbumin which both declined progressively. CSF/plasma ratios were dissimilar for different proteins, and changed with increasing gestation. These findings support the concept that the human fetal blood brain barrier matures early.

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.

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.
