Sequential probability tests were employed to examine genetic linkage among, cattle A, B, C, F, J, L, M, S, Z, and R' blood group loci, the hemoglobin locus, the serum transferrin, amylase, and alkaline phosphatase loci, and the milk protein loci beta-lactoglobulin, alpha S1-casein, beta-casein, and kappa-casein. Linkage was evident between the A and hemoglobin loci, the J and beta-lactoglobulin loci, the alpha S1-casein and beta-casein loci, the alpha S1-casein and kappa-casein loci, and the beta-casein and kappa-casein loci. Recombination fractions for these respective combinations were 0, .18, .03, .04, and .06. There was a suggestion of possible loose linkage (recombination fraction = .4) between the beta-lactoglobulin locus and the casein complex. Linkage could be excluded for most other combinations at .25 recombination.

A group of 291 children aged 3 weeks to 6 1/2 years was examined at a public maternal and child health center and 260 of them - who were considered to be healthy - were included in the present study. By venipuncture, serum was obtained for the analysis of 6 enzymes, and plasma for the estimation of 9 proteins and for lipid analyses. In different age groups, high levels were found for alkaline phosphatase, lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, creatine kinase and gamma-glutamyl transferase. Haptoglobin, alpha 1-antitrypsin, prealbumin and transferrin were present at low concentrations during the first months of life. Transferrin rose later in childhood to above adult levels. Only immunoglobulin M showed a sex difference, with higher values for girls. Breast-fed infants had higher (non-fasting) concentrations of cholesterol and triglycerides than formula-fed babies, and they also had higher levels of aspartate aminotransferase and alanine aminotransferase.

Biochemical polymorphic gene frequency profiles from blood samples of two outbred and seven inbred lines of chickens were studied for hemoglobin, albumin, transferrin, alkaline phosphatase, esterase II, and leucine aminopeptidase, and from egg samples of these lines for ovoalbumen, ovoglobulin (G2 and G3), and conalbumen. Complete gene fixation was found for hemoglobin, albumin, transferrin, ovalbumin, ovoglobulin, and conalbumin. The same alleles were fixed in each system in each line. For four systems, a particular allele within a system predominated in seven populations; gene frequencies ranged from 0.60 to 0.98. For esterases I and II, the genes Es-IB and Es-IIS ranged in frequency between 0.82 and 0.97, and between 0.64 and 0.93, respectively. For ovoglobulin, G2B ranged between 0.75 and 1.00 with four lines fixed for this allele. The rather remarkable similarity of gene frequency profiles among lines, several of which are only remotely related, suggests that certain characteristic polymorphic frequencies for these biochemical polymorphisms possess higher adaptive values in an evolutionary sense.

Fifteen various serum and urine parameters were evaluated as indicators of renal alterations induced by lead in 82 male workers of a battery plant chronically exposed to lead (median of blood lead concentration: 2.03 mumol/l). The control group comprised 44 non-exposed healthy volunteers (0.34 mumol/l). High-molecular-mass proteins (transferrin, immunoglobulin G (IgG), (albumin)) were determined in urine as markers of glomerular integrity; low-molecular-weight proteins and parenchymal enzymes (alpha 1-microglobulin, beta 2-microglobulin, retinol-binding protein, lysozyme, ribonuclease, N-acetyl-beta-D-glucosaminidase (NAG), alanine aminopeptidase (AAP), alkaline phosphatase (AP), gamma-glutamyltransferase (GGT)) as indicators of changes in the proximal tubule; Tamm-Horsfall glycoprotein and kallikrein as markers of the distal tubule. There was a positive correlation between tubular indicators and blood lead concentration as well as the erythrocyte protoporphyrin (EPP). About 30% of the lead-exposed workers showed an increased excretion of alpha 1-microglobulin, NAG, ribonuclease, and/or Tamm-Horsfall protein, whereas the glomerular indicators remained unchanged. The combined determination of NAG and alpha 1-microglobulin in urine could be helpful in the early detection of lead-induced changes in the nephron.

Endocrine abnormalities in patients with chronic renal failure are well documented. The present study aimed to assess the influence of long-term erythropoietin (EPO) therapy on endocrine abnormalities in hemodialyzed patients. Two groups of hemodialyzed patients, each of which comprised 17 subjects, were examined. The first group was treated by EPO (EPO group) while the second one did not receive this hormone (No-EPO group). A complete biochemical and hormonal check-up was performed before and at the 3, 6, 9, and 12 month points of the study period. Normal values for the estimated parameters were obtained in appropriately selected sex- and age-matched healthy subjects. After EPO therapy, an increase of the hematocrit value from 21.8 +/- 0.9 to 32.6 +/- 0.9% was observed, which was accompanied by a significant decline of plasma ferritin and saturation of transferrin. In patients of the No-EPO group, a significant although less marked rise of the hematocrit value (21.4 +/- 0.4 to 24.2 +/- 0.6%) was also noticed. EPO therapy did not change plasma levels of electrolytes (Na, K, Ca, inorganic phosphate), osteocalcin, creatinine, glucose, and alkaline phosphatase as well as plasma concentrations of calcium-related hormones (PTH, calcitonin, 1,25[OH]2D3), vasopressin, and triiodothyronine. EPO treatment induced a significant decrease in somatotropin, prolactin, follitropin, lutropin, ACTH, cortisol, plasma renin activity, aldosterone, noradrenaline, adrenaline, dopamine, glucagon, pancreatic polypeptide, and gastrin plasma levels and an increase in plasma insulin, estradiol, testosterone, atrial natriuretic peptide, thyrotropin, and thyroxine.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-two patients with chronic renal failure were randomly assigned to a conventional low-protein diet containing 0.6 g protein/kg/day or a very-low-protein diet containing 0.4 g protein/kg/day supplemented with essential amino acids; they were followed up for 9 months. There were no significant changes in body mass index, arm muscle area, percentage body fat, serum albumin and transferrin levels in any of the groups; neither was there any difference between the groups in respect of these parameters. Renal function, as measured by the reciprocal of serum creatinine over time, stabilised in both groups during intervention, with no significant difference between the groups. There was however no correlation between changes in renal function and changes in blood pressure, or dietary intake of protein, phosphorus, cholesterol, polyunsaturated and saturated fatty acids. There were also no significant changes and no significant differences between the groups in serum levels of parathyroid hormone and alkaline phosphatase, urine cyclic adenosine monophosphate, tubular reabsorption of phosphate, and the theoretical renal threshold for phosphate. The results of this study suggest that the supplemented very-low-protein diet was not superior to the conventional low-protein diet in terms of its effect on protein-energy status, renal function and biochemical parameters of renal osteodystrophy.

Recent studies have indicated that lactoferrin may act as a cell mitogen. The effect of human and bovine lactoferrins on the proliferation and differentiation of a human intestinal epithelial cell line (Caco-2) was investigated and compared with that of human transferrin. Caco-2 cells were cultured in serum-free media supplemented with both iron-unsaturated and -saturated forms of the iron-binding proteins. Cell proliferation and differentiation were evaluated by examining growth curves and measuring sucrase and alkaline phosphatase activities of brush border membrane fractions, respectively. The iron-binding status of lactoferrins and transferrin affected the proliferation of Caco-2 cells. The iron-saturated forms of human (S-hLf), bovine (S-bLf) lactoferrins and human transferrin (S-hTf) enhanced cell proliferation, while iron-unsaturated forms (U-hLf, U-bLf, and U-hTf) suppressed it. Iron-binding status also determined the effect of lactoferrin and transferrin on cellular differentiation, but this effect differed for different brush border enzymes. S-hTf enhanced sucrase activity more than S-hLF or S-bLf. Both U-hLf and U-bLf markedly suppressed sucrase activity. U-hTf suppressed alkaline phosphatase activity appreciably, while the other iron-binding proteins showed no significant effect on it. Lactoferrin and transferrin may modulate the proliferation and differentiation of intestinal epithelial cells, but their efficacy depends on their saturation with iron.

A chondroitin sulfate-dermatan sulfate proteoglycan was isolated from bovine aorta intima by extraction of the tissue with 4 M guanidine hydrochloride. The proteoglycan was purified by CsCl isopycnic centrifugation followed by gel filtration and ion exchange chromatography. A monoclonal antibody C8F4 was developed to this core protein. The characteristics and specificity of the antibody were studied by an enzyme-linked immunosorbent assay (ELISA) using an alkaline phosphatase conjugated antibody (goat anti-mouse IgG). The antibody binding to the core protein was found specific and optimal at pH 7.0. The antibody recognizes either intact chondroitin sulfate-dermatan sulfate proteoglycan monomer, chondroitinase ABC digested monomer or chemically deglycosylated proteoglycan. Free chondroitin sulfates, keratan sulfate and hyaluronic acid did not compete for the antigenic sites in ELISA. Limited hydrolysis of the core protein by trypsin resulted in three peptides and only the peptide with a molecular weight M(r) = 40,000 was found capable of binding to hyaluronic acid. The antibody C8F4 recognized this hyaluronic acid binding peptide but did not recognize the other two peptides suggesting that the epitope(s) for this antibody is in the hyaluronic acid-binding region of the core protein. The antibody recognized the core proteins from bovine nasal cartilage proteoglycan and human aorta proteoglycan but did not recognize bovine aorta link protein, bovine serum albumin, human serum albumin, human transferrin, collagen Type I and fibronectin. The antibody was found useful to localize proteoglycans in atherosclerotic lesions in human aorta by immunohistochemical techniques.

We tested the diagnostic sensitivity of various urinary analytes for detecting cadmium-induced nephropathy at an early stage. We investigated 73 healthy persons (control group 1) and individuals exposed to cadmium, either environmentally (n = 36, risk group 2) or occupationally (n = 62, exposed group 3). All data were related to limits of the central 95% reference intervals of the control group. The serum creatinine and ribonuclease values, indicators of the glomerular filtration rate, were not different in the three groups. In the exposed persons (group 3), proximal tubular indicators (low-M(r) proteins lysozyme, ribonuclease, retinol-binding protein, and alpha 1-microglobulin) were more often increased than the glomerular indices (higher-M(r) proteins transferrin, IgG, and albumin). Both the low-M(r) proteins and tubular enzymes were differently altered in their excretion rates. Alanine aminopeptidase, alkaline phosphatase, and N-acetyl-beta-D-glucosaminidase increased even in the risk group 2. alpha 1-Microglobulin was increased in the exposed persons whose cadmium excretion was < 5 mumol/mol creatinine. The combined determination of alpha 1-microglobulin and N-acetyl-beta-D-glucosaminidase exceeded the corresponding upper reference limits in 30% of group 2 and 39% of group 3. We recommend screening for these two analytes to detect cadmium-induced renal dysfunction at an early stage.
