A literature review of the effect of oral contraceptive (o.c.) use on various metabolic processes is presented. Several studies show an adverse effect of o.c. use on subclinical diabetes and on patients with manifest insulin-independent diabetes. Some researchers have found a beneficial effect of o.c. use on older diabetics. It has not been determined whether the estrogen or gestagen component of o.c.s is responsible for this decrease in glucose tolerance, nor has the mechanism for this effect been discovered. Changes in various plasma protein concentrations have been observed during o.c. use, which affect the blood coagulation and the blood pressure regulation systems. The estrogen component appears to be responsible for the increase in the serum triglyceride concentration during o.c. use; the mechanism is still unknown. Some studies indicate that o.c. use causes an increase in serum cholesterol levels, which could promote gall stone formation. An increase in Vitamin A concentration has been observed during o.c. use. Riboflavin, folic acid, vitamin B 12, and ascorbic acid levels have been shown to decrease during o.c. use. A decrease in pyridoxin levels during o.c. use indicates an increased metabolism of tryptophan to nicotinic acid robosyl-5-phosphate. This would cause a decrease in serotonin production, which could be a cause of the depression experienced by some o.c. users. An increase in the plasma copper and caeruloplasmin levels during o.c. use is apparently due to the estrogen component. An increase in transferrin and the serum iron levels have been observed during o.c. use. Contradictory findings are reported concerning the plasma concentration of zinc.

Using single radial immunodiffusion, ten glycoproteins from non purulent pleural fluids have been estimated in different diseases. For five proteins (prealbumin, ceruloplasmin, alpha2HS-glycoprotein, transferrin, beta2-glycoprotein 1) the results have been found not to correlate with the causal disease. However for orosomucoid, alpha1-antitrypsin, haptoglobin, alpha2-macroglobulin and hemopexin, there was good correlation between proteins levels and aetiology. The glycoprotein concentration was low in mechanical effusions from cirrhosis and chronic cardiac failure. It was high in inflammatory, post-embolism and particularly neoplastic effusions. A raised orosomucoid level occurred as the most characteristic of cancer states especially when associated with a parallel increase of the four other glycoproteins. A simultaneously elevated level of these five pleural glycoproteins seems to be a good and significant biological sign for neoplastic effusion diagnosis.

The concentrations of nine proteins, alpha-1-acid glycoprotein, antitrypsin, prealbumin, transferrin, albumin, IgG, ceruloplasmin, IgA and alpha-2-macroglobulin, have been determined in the serum and CSF of two groups of patients, one control and one experimental, by an immunological method. The experimental group were patients suffering from grand mal epilepsy. The control group showed no detectable neurological disorder. In the group of grand mal epileptics, only prealbumin showed a significant elevation in CSF when compared with the control group. In contrast, the rest of the proteins are decreased with respect to the controls except for alpha 1-acid glycoprotein and transferrin. The results from this study also suggest that something more than an ultrafiltration process dependent upon molecular weight, is important in determining the concentration of some serum proteins in the CSF.

The lack of internationally comparable reference standards for plasma proteins causes problems. For this reason, it is only possible to evaluate the "accuracy" of measurements by comparison of methods. Differences in results which may sometimes be based on technical procedure, physical chemistry or biology are gone into with reference to diagnostically important examples such as albumin, transferrin, ceruloplasmin, fibrinogen and complement 3. It is shown which plasma protein constellations may frequently be expected in certain reactions and what protein patterns have principal importance in clinical practice, e.g. in acute and chronic inflammatory diseases, protein depletion diseases and in liver diseases.

Factors related to iron metabolism were determined in 20 United States Navy divers during 8 d of air saturation-excursion hyperbaric exposures. During these simulated dives progressive and correlated increases in serum ferritin and iron occurred. No significant changes were observed in bilirubin, hemoglobin, ceruloplasmin, transferrin, copper, or total iron binding capacity. The significance of the increased serum ferritin is discussed in relation to bone marrow damage and early detection of aseptic bone necrosis.

Antigenic components of buffalo (Bos bubalis) serum, which were also components of buffalo colostrum, seminal plasma, milk whey, saliva, and tears, were investigated by the ager gel diffusion test and immunoelectrophoresis. Immunoglobulins of buffalo serum were identified by immunoelectrophoresis employing rabbit-anti-buffalo serum and rabbit-anti-buffalo gamma-globulin. Based on immunoelectrophoretic patterns immunoglobulin G (IgG), IgGA, and IgM were detected both in the serum and colostrum of buffaloes. Tears contained both IgG and IgM. Cross-reactions of buffalo serum with seminal plasma, saliva, and milk whey were observed only in the IgG region. By polyacrylamide gel electrophoresis, lipoprotein (5.2% +/- 0.41), IgM (11.4% +/- 3.1), IgG (9.4% +/- 0.98), haptoglobin 21.8% +/- 3.73), transferrin (10.4% +/- 2.15), ceruloplasmin (7.8% +/- 1.3), postalbumin (20.8% +/- 2.09), and albumin (13.7% +/- 0.75) were identified provisionally.

One hundred and ninety five wild pigs from two different regions of Poland were investigated for transferrin, amylase and ceruloplasmin polymorphism. A new tranferrin phenotype Tf PB was detected. This phenotype differed from Tf AB in the electrophoretic mobility of the more anodal transferrin. Tf P is assumed to be the product of a new allele Tf P at the Tf locus. Two amylase phenotypes Am 1-2 and Am 2 were observed. The Am 1 allele was absent from the pigs in the Poznan region. Only one ceruloplasmin phenotype, Cp B, was found.

1. Purified caeruloplasmin was shown to inhibit lipid autoxidation induced by ascorbic acid or inorganic iron in the following systems: (a) an emulsion of linolenic acid in water; (b) an untreated ox brain homogenate in phosphate buffer; (c) a similar homogenate whose susceptibility to autoxidation had been abolished by dialysis or by heating and then restored by the above pro-oxidants. 2. The optimum conditions for this antioxidant activity were studied. 3. Caeruloplasmin did not inhibit autoxidation by u.v. irradiation in dialysed or preheated homogenates. 4. The apoprotein (without copper) had no antioxidant activity, whereas CuSO4 alone was much less effective as an antioxidant. 5. Iron-free transferrin also had some antioxidant activity.

Phenotype and gene frequencies are presented for eight polymorphic systems among the Nubians of South Egypt, namely, acid phosphatase, glucose-6-phosphate dehydrogenase, adenylate kinase, 6-phosphogluconate dehydrogenase, esterase D, phosphoglucomutase I, peptidase A, and haptoglobin. Eleven systems, namely, albumin, ceruloplasmin, hemoglobin, lactate dehydrogenase, isocitrate dehydrogenase, phosphohexose isomerase, malate dehydrogenase, peptidase B and C, phosphoglucomutase II, and transferrin were found to be monomorphic. A single electrophoretic variant of phosphohexose isomerase were observed.

Copper, caeruloplasmin, transferrin, albumin, and total protein were measured in the serum and synovial fluid of 40 patients with rheumatoid arthritis and 40 patients with osteoarthrosis. A raised synovial fluid copper and caeruloplasmin have been found to be characteristic of rheumatoid effusions. The relation between copper and caeruloplasmin in synovial fluid differs from that in serum. Synovial fluid caeruloplasmin was increased disproportionately in relation to other plasma proteins present in rheumatoid effusions.
