One hundred and five infants of birth weight 2000 g or less who received peripherally administered parenteral nutrition for periods of three or more weeks, were randomly assigned to groups receiving different amounts of zinc and copper supplement. The blood concentrations of zinc, copper, retinol-binding protein, prealbumin, alkaline phosphatase and aspartate transaminase were followed weekly. Mean serum zinc, retinol-binding protein and prealbumin declined significantly over time while alkaline phosphatase rose. Only the group receiving the highest zinc supplement maintained a mean serum zinc concentration within the normal range at seven weeks. No difference in the protein or enzyme concentrations was found between the different zinc supplement groups. No difference was seen in serum copper or ceruloplasmin between copper dose groups although one intravenous supplement was double that of the other.

The proteins of 46 human bile specimens, collected by several different routes have been studied by crossed immunoelectrophoresis, by rocket immunoelectrophoresis and by radioimmunoassay. The results were analysed by plotting the variation in the bile: plasma ratio of particular proteins against molecular weight and by examination of the correlation between the concentrations of different proteins in the biles of different patients. Our results show that the majority of human bile proteins derive from plasma although bile specific proteins are always present. The majority of plasma proteins appear to enter bile by a 'sieving' mechanism which results in an inverse relationship between the bile: plasma ratio and the molecular weight. In addition there was a very high degree of correlation between the biliary concentrations of alpha 2-macroglobulin, IgG, haptoglobin, haemopexin, albumin, prealbumin, and orosomucoid. A number of other proteins namely thyroxine binding globulin, GC globulin and alpha 2HS-glycoprotein appeared in bile at concentrations greater than those expected if entry is by the sieving mechanism. These three proteins, however, are of rather low molecular weight and the reason for the lack of correlation appears to be individual variation in the 'pore size', presumably reflecting variation in the porosity of tight junction between hepatocytes. Although the majority of human bile proteins would appear to enter bile by a molecular weight-dependent pathway, four proteins, namely secretory IgA, IgM, haemoglobin and caeruloplasmin, showed significant deviation from the predicted relationship and probably enter bile at least partly by transport across cells. The concentration of beta 2-glycoprotein I was also much greater than expected from its molecular weight. The reason for this is not yet clear but may well reflect a very efficient and specific transport mechanism.

The serum concentration of 19 serum proteins was determined by electrophoresis in 42 patients with Crohn's disease and 36 patients with ulcerative colitis. The results were compared with 78 healthy persons as matched controls. Distinctive, but similar, changes were present in the two diseases. An increased serum concentration of orosomucoid, alpha(1)-antitrypsin, easily precipitable glycoprotein, alpha(1)-antichymotrypsin, haptoglobin, and haemopexin was present. The serum concentration was decreased for prealbumin, albumin, alpha(2)-HS glycoprotein, caeruloplasmin, alpha(2)-macro-globulin, and transferrin. No significant difference between the two diseases existed as far as the serum protein pattern was concerned. Certain proteins, ;the acute phase reactants' (orosomucoid, alpha(1)-antitrypsin, alpha(1)-antichymotrypsin, and haptoglobin) and the immunoglobulins were clinically useful, since their serum concentration reflected the grade of activity of the disease. A pronounced elevation of haptoglobin compared with that of the other ;acute phase reactants' was present in patients with Crohn's disease complicated by suppurative fistulas or abscesses. Patients with active Crohn's disease who responded favourably to medical treatment had significantly higher immunoglobulin levels than patients not responding. A similar observation, though not statistically significant, was made in patients with ulcerative colitis.

Urine was collected from 6 healthy male adults at rest and from 20 male adults after a marathon race (25 miles). The concentrated urines were quantitatively analyzed, by single radial immunodiffusion, for their content in 12 different plasma proteins: tryptophan-rich prealbumin, albumin, alpha(1)-acid glycoprotein, alpha(1)-antitrypsin, ceruloplasmin, haptoglobin, Gc-globulin, transferrin, hemopexin, beta(2)-glycoprotein I, gammaA-globulin, and gammaG-globulin.Albumin, gammaA-globulin, and gammaG-globulin represent the major part of the plasma proteins detected in normal urine excreted by humans at rest (12, 0.5, and 2.5 mg respectively, out of a total excretion of 17.5 mg of plasma proteins per 24 hr). The other plasma proteins were excreted at a lower rate (< 0.4 mg/24 hr). The relative content of tryptophan-rich prealbumin, alpha(1)-antitrypsin, Gc-globulin, transferrin, and gammaG-globulin was lower in normal urine than in normal serum, whereas that of alpha(1)-acid glycoprotein, beta(2)-glycoprotein I, and gammaA-globulin was higher. The ratio of gammaG-globulin to gammaA-globulin was 4.9:1. When plotted on a logarithmic scale, no direct relationship between the molecular weight of a protein and the value of its renal clearance could be observed.Strenuous exercise increased (up to 50-fold) the excretion of plasma proteins which represent 82% of the total proteins found in urine, instead of 57% in urine collected from humans at rest. There was particularly a significant rise of tryptophan-rich albumin, albumin, alpha(1)-acid glycoprotein, transferrin, gammaA-globulin, and gammaG-globulin (0.26, 127, 11.8, 3.3, 1.2, and 2.0 mug respectively, out of a total excretion of 167 mug of plasma proteins per min). The ratio of gammaG-globulin to gammaA-globulin was 16:1. After exercise, the renal clearance of proteins increased from 2 to 40 times, but, as for the urine of normal subjects at rest, no direct relationship between molecular weight and renal clearance could be observed.

The synthesis of gammaG, gammaA, gammaM, beta(1C)/beta(1A), C'1 esterase inhibitor, ceruloplasmin, transferrin, hemopexin, haptoglobin, fibrinogen, alpha(1)-antitrypsin, orosomucoid, beta-lipoprotein, alpha(2)-macroglobulin, and prealbumin was studied in 15 normal human embryos and fetuses of 29 days to 18 wk gestation and in the yolk sacs of four embryos from 5.5 to 11.5 wk gestation using tissue culture in (14)C-labeled amino acids followed by radioimmunoelectrophoresis. The human embryo as early as 29 day gestation synthesized beta(1C)/beta(1A), C'1 esterase inhibitor, transferrin, hemopexin, alpha(1)-antitrypsin, beta-lipoprotein, alpha(2)-macroglobulin, and prealbumin in culture. At 32 days gestation ceruloplasmin and orosomucoid were also synthesized, but synthesis of fibrinogen was not observed before 5.5 wk. Synthesis of gammaM occurred as early as 10.5 wk gestation, and gammaG synthesis was found in cultures as early as 12 wk gestation; gammaA synthesis was not detected in any of the tissue cultures. With the exception of the gamma-globulins, each of the proteins studied was synthesized by the liver, but additional sites of synthesis for some of these proteins were also found. Synthesis of gammaG and gammaM occurred primarily in the spleen, but other sites of synthesis were noted as well. Changes in the concentrations of most of these proteins and plasminogen in embryonic and fetal serum from 5.5 to 41 wk gestation, in amniotic fluid from 6.5 to 38 wk gestation, and in the sera of neonates during the 1st 3 wk postpartum are described. Although gammaA, gammaM, ceruloplasmin, or haptoglobin were not detectable in some of the embryonic and fetal sera, gammaA and ceruloplasmin were both present as early as 6.5 wk gestation, haptoglobin by 9.5 wk gestation, and gammaM by 17 wk gestation. Each of the other proteins were present in all of the sera examined.

Blood levels of prealbumin, retinol-binding protein, ceruloplasmin and transferrin were monitored during the rehabilitation of thirty protein-energy malnourished children. The children aged between six and fifty-four months were rehabilitated on an out-patient basis and fed locally prepared good quality food while the mothers were given nutrition education coupled with health education. The initial mean anthropometric values and plasma transport protein levels were significantly lower in these children when compared with values obtained from 10 apparently healthy children presenting with no signs or symptoms suggestive of any form of malnutrition. At the end of the rehabilitation period, there was no significant difference in plasma transport protein levels between the previously malnourished children and the normal controls although the malnourished children still demonstrated significant weight deficit.

The serum concentrations of six glycoproteins (alpha 1-acid glycoprotein, AGP; haptoglobin, Hp; alpha 1-antitrypsin, AT; ceruloplasmin, Cp; prealbumin, PALB; and alpha 2-macroglobulin, MACRO) have been estimated serially in nine advanced breast cancer patients who received a total of 24 intravenous infusions of methotrexate (MTX). The serum glycoprotein levels taken before the first drug exposure did not relate with the prognosis of these patients. In eight patients, constantly high or rising levels of AGP, Hp and AT during consecutive infusions of the drug were associated with continued metastatic disease. A transient tumour regression occurred in one patient which correlated with falling serum levels of these proteins into the normal range. The serum levels of Cp, PALB and MACRO did not correlate with the clinical status of these patients during treatment. Possible factors which may influence the serum levels of these glycoproteins in cancer patients during therapy are discussed.

The change in the protein concentration in blood serum was investigated after implantation of a pacing system with epoxide surface (group A, 20 patients) or metallic case (group B, 9 patients). The response to surgical intervention was equal in both groups. In the first period following operation the acute phase reaction took place in terms of increasing concentrations of alpha-globulins, especially alpha 1-acid glycoprotein, alpha 1-antitrypsin, ceruloplasmin, haptoglobin, and beta 1A/C-globulin, Simultaneously, a decrease in prealbumin, albumin, beta-globulin, in particular haemopexin and transferin concentration appeared. As for immunoglobulins, a decrease in IgG and increase in IgA and IgM globulins was observed. In the course of a longer period of time following implantation (group B--three months; group A--two years) a decrease of almost all investigated proteins was observed with exception of increased IgA globulin and transferin in group A.

8 healthy (apart from pelvic endometriosis) women were given daily doses of 0.125, 0.250, and 0.500 mg of desogestrel or 5 mg of lynestrenol orally in a randomized order. Duration of each treatment was 6 weeks. Serum was analyzed for sex hormone binding globulin (SHBG) ceruloplasmin, cortisol binding globulin (CBG), thyroxine binding globulin (TBG) and prealbumin using an electroimmunoassay. Serum 17Beta-estradiol (E2) and testosterone (T) were analyzed by radioimmunoassay. Vaginal cytology was studied using the maturation value (MV). E2 levels were depressed by desogestrel and lynestrenol apart from values in 2 women after 0.125 mg desogestrel. T concentration was suppressed by desogestrel but not by lynestrenol. SHBG concentration and MV were dose-dependently suppressed indicating an antiestrogenic or possibly androgenic effect of desogestrel and lynestrenol. No androgenic or anabolic effects of desogestrel were however seen, e.g., suppression of TBG content or increase in prealbumin levels. For lynestrenol, however, a small but significant increase in prealbumin concentration indicated a weak and androgenic/anabolic effect. No estrogenic effects were seen, e.g. increases in ceruloplasmin, CBG levels or in elevation of MV. A depressed SHBG production ability in the hepatocytes during treatment with 19-nortesterone derivatives is postulated, possibly due to competitive receptor binding.

A human hepatoma cell line, HuH-7, which was established from a hepatocellular carcinoma, was found to replicate continuously in a chemically defined medium when the medium was supplemented with Na2SeO3. The cells grew better in this medium than in serum-containing medium without any adaptation period. Other established human hepatoma and hepatoblastoma cell lines, HuH-6 cl-5, PLC/PRF/5, huH-1, and huH-4, also grew in the defined medium. Although HLEC-1 cells failed to proliferate continuously with Na2SeO3 alone, they grew if a cell-free conditioned medium from HuH-7 cells was added to the medium. These cell lines, except the HLEC-1 cell line, produced the following human plasma proteins among those examined: albumin, prealbumin, alpha 1-antitrypsin, ceruloplasmin, fibrinogen, fibronectin, haptoglobin, hemopexin, beta-lipoprotein, alpha 2-macroglobulin, beta 2-microglobulin, transferrin, lipoprotein, alpha 2-macroglobulin, beta 2-microglobulin, transferrin, Complement Components 3 and 4, and alpha 1-fetoprotein. Beside plasma proteins, the media from HuH-7, HuH-6 cl-5, PLC/PRF/5, and huH-1 contained anti-carcinoembryonic antigen-reactive proteins, and those from PLC/PRF/5, huH-1, and huH-4 medium contained hepatitis B surface antigen. These proteins were detected during periods of serial cultivation over 9 months under the above culture conditions. The hepatoma cell lines grown in the fully defined synthetic medium may provide a new approach for investigating the growth and metabolism of human hepatoma cells in vitro.
