We describe 5 preterm infants (25th to 30th week of gestation) suffering from alimentary copper deficiency. The diagnosis was confirmed by low serum copper and caeruloplasmin concentrations. Characteristic clinical findings were repeated apnoeic attacks, hypopigmentation of skin and hair, anaemia, neutropenia and leucopenia refractory to other therapy, as well as increasing serum alkaline phosphatase activity in the first month of life. Starting in the 3rd to 12th week of life the radiographic findings were general skeletal osteoporosis and retardation, metaphyseal radiodense lines, irregular metaphyses, cupping and spurring of the metaphyses, followed by multiple fractures and subperiosteal new bone formation and enlarged costochondral junctions. Copper was substituted orally resulting in complete healing of fractures and improvement in both clinical symptoms and laboratory parameters.

Establishing a diagnosis of fulminant Wilson's disease can be difficult because Kayser-Fleischer rings may not be present and parameters of copper metabolism, including serum and urinary copper, and serum ceruloplasmin levels are neither specific nor diagnostic. In this study, ratios of both the serum alkaline phosphatase to total bilirubin and aspartate transaminase to alanine transaminase were constructed to evaluate their usefulness in differentiating fulminant hepatic failure caused by Wilson's disease (n = 6) from other etiologies (n = 43). An analysis of the data showed that cutoff values of less than 2.0 for the alkaline phosphatase-total bilirubin ratio and greater than 4.0 for the aspartate transaminase ratio were associated with a diagnosis of fulminant hepatic failure caused by Wilson's disease only (P less than 0.001). The alkaline phosphatase-total bilirubin ratio of less than 2.0 provided 100% sensitivity and specificity in identifying fulminant hepatic failure caused by Wilson's disease from other types of fulminant hepatic failure.

Serum ferritin, prealbumin, pseudocholinesterase, alpha-1-antitrypsin and caeruloplasmin were determined in control subjects and patients with pancreatic cancer, chronic pancreatitis or extra-pancreatic disease mainly of gastrointestinal origin, in order to investigate the different hepatic changes which influence serum ferritin in chronic pancreatic and other digestive diseases. Increased circulating ferritin was found in pancreatic cancer and extra-pancreatic disease when compared to controls. Correlations were detected between ferritin and the other proteins investigated and between ferritin and total bilirubin, alkaline phosphatase and alanine aminotransferase. Multiple regression analysis demonstrated that cholestasis accounts for 45% of circulating ferritin, the acute-phase response accounted for 18% and decreased liver function accounted for 11%. We conclude that the increase in serum ferritin in chronic pancreatic and other gastrointestinal diseases largely depends on liver changes, with cholestasis probably playing a primary role.

Biochemical polymorphism of 116 dwarf goats has been studied by starch gel electrophoresis. The systems haemoglobin, ceruloplasmin and erythrocyte esterase were monomorphic. 4 loci were found to be polymorphic: amylase, transferrin, alkaline phosphatase, and albumin. The allele frequency of these traits was given.

Eleven potential biochemical markers were measured in serum from 33 patients with malignant and 13 with benign colorectal disease: four isoenzymes (creatine kinase-BB, homoarginine-sensitive alkaline phosphatase, salivary-type amylase, and macro-creatine kinase type 2), five specific proteins (ferritin, alpha 1-acid glycoprotein, C-reactive protein, alpha 1-antitrypsin, and ceruloplasmin), one oncofetal antigen (carcinoembryonic antigen, CEA), and one hormone (beta human choriogonadotropin). The sensitivity of individual markers for the detection of early-stage malignancy (n = 11) ranged from 0% to 64% (CEA 18%); for late-stage colon malignancy (n = 12) from 8% to 83% (CEA 83%). Specificity in patients (n = 10) with benign intestinal disease ranged from 80% to 100% (CEA 100%). The five most-sensitive markers--C-reactive protein, alpha 1-glycoprotein, CEA, macrocreatine kinase type 2, and homoarginine-sensitive alkaline phosphatase--were selected for use as a "colon panel." In retrospective comparison, use of the colon panel instead of CEA alone increased sensitivity by 17% and 64% for late-and early-stage cancer, respectively; specificity, however, decreased by 30%, but should improve with serial testing.

A noncompetitive, colorimetric enzyme-linked immunoadsorbent assay (ELISA)+ was developed for measuring rat ceruloplasmin in serum and in medium from culture hepatocytes. The assay utilized polystyrene immobilized antibody which bound ceruloplasmin which then bound biotinylated antibody. The biotinylated antibody-antigen complex was detected with strepavidin-alkaline phosphatase conjugate. Standard curves for rat ceruloplasmin were constructed in the range between 10 and 50 ng/mL. Increases of 10 ng produced an increase in A403 of more than 0.2. With this immunoassay, serum ceruloplasmin levels were found to average 35 mg Cp/dL in control rats and 87 mg/dL in rats with experimental inflammation. Liver parenchymal cells secreted 1.6 micrograms Cp/5 x 10(5) cells/24 h. This ELISA assay for ceruloplasmin will facilitate studies on the regulation of ceruloplasmin synthesis and secretion in both intact rats and isolated hepatocytes.

To determine the adequacy of zinc and copper supplementation for infants receiving total parenteral nutrition (TPN), we performed 24-h balance studies in infants with diarrhea and infants who had recently undergone surgery. Measurements were made at base line, 1, and 2 wk. Mean serum Zn and Cu levels of the diarrhea group remained normal and were low in the postoperative group but normalized over the study period. Mean 24-h Zn and Cu balances were positive in infants with diarrhea and negative in postoperative infants. The high Zn and Cu content in the gastrointestinal fluid loss associated with surgery may have accounted in part for this finding. Normal serum levels of Zn and Cu did not guarantee positive balance. No significant changes were found in serum albumin, alkaline phosphatase, or ceruloplasmin. The current Zn and Cu recommendations may be appropriate only for hospitalized infants who have no excessive gastrointestinal fluid losses.

Twenty-five samples obtained by amniocentesis were studied in 25 pregnant women between 35 and 40 weeks of pregnancy with hypertension. The following biochemical investigations were done in the samples: total protein, beta-lipoproteins, cholesterol, uric acid, urea, creatinine, AlAT and AspAT, total alkaline phosphatase and its thermostable isoenzyme, ceruloplasmin and alpha-amylase. The results were analysed in relation to the development of the respiratory distress syndrome in the newborn and were subjected to statistical analysis. In the amniotic fluid of hypertensive mothers in whose children the respiratory distress syndrome developed, reduction was found in the concentrations of beta-lipoproteins and cholesterol. This may have a prognostic significance in the prediction of respiratory distress in early neonatal period.

The genetic structure of two Chukot Evens subpopulations (314 individuals) for electrophoretic protein systems and taste sensitivity to PTC was studied. 17 of the 39 loci were polymorphic (43.59%). The following systems were completely monomorphic: diaphorase NAD H (Dia); glucose-6-phosphate dehydrogenase (G-6-PD); glutamatoxalate transaminase (GOT); carbonic anhydrase (Ca-1); catalase (Ct), lactate dehydrogenase (loci LDH-A and LDH-B); leucine aminopeptidase (Lap); malate dehydrogenase (MDH); purine nucleoside phosphorylase (PNP); superoxide phosphorylase (PNP); superoxide dismutase (SOD); phosphoglucomutase-2 (PGM2); cholinesterase (locus E1); red cell esterase (4 loci); albumin (Alb); hemoglobin (Hb A and B); ceruloplasmin (Cp); and blood, gren, using the standard method. The following systems were polymorphic: red cell acid phosphatase (AcP); phosphoglucomutase-1 (PGM1); 6-phosphogluconate dehydrogenase (PGD); glutamatepyruvate transaminase (GPT); glyoxalase-1 (GLO-1); esterase (EsD); adenilatkinase (AK); alkaline phosphatase (Pp); cholinesterase (locus E2); haptoglobin (Hp); transferrin (Tf); group-specific component (Gc) and ABO, MN, Lewis, P blood groups and taste sensitivity to PTC. The following allele frequencies for polymorphic loci have been detected: AKI = 0.994; GLO = 1I = 0.082; GPT1 = 0.653; AcPA = 0.400; AcPB = 0.599; AcPC = 0.001; PGDA = 0.944; PGM1(1) = 0.906; EsD1 = 0.897; E2+ = 0.048; HpI = 0.394; GcI = 0,919; Tfc = 0.987; r(O) = 0.669; p(A) = 0.184; q(B) = 0.146; M = 0.711; Le = 0.411; P1+ = 0.521; t = 0.295. The genetic structure of Chukot Evens population is significantly nearer to that of the other ethnic groups of the North-East, in comparison with the genetic structure of Evenks of the Middle Siberia.

A monkey model has been set up for protein calorie malnutrition and calcium deficiency. Oral exposure of 5ppm Cd/kg body wt./day for 24 weeks led to increased excretion of Cd, metallothionein (MT) and zinc. Rehabilitation of PCM monkeys for one year resulted in gradual reduction and finally complete disappearance of urinary metallothionein. During Cd exposure, the accumulation of Cd and induction of MT was significantly higher in liver, kidney and intestine. MT was also induced in heart, lung and testis of Cd exposed PCM and calcium deficient monkeys. Metallothionein from liver has been resolved into three isoforms, viz MTa, MTb and MTc on DEAE-Sephadex A 25 ion exchange column. MTc is the major isoform in Cd-treated, normal and protein calorie malnourished monkeys whereas MTb is the major isoprotein in the cadmium treated calcium deficient monkeys. The iso-metallothioneins varied in their metal composition in the nutritional stress conditions and showed different capacities to reactivate apo-enzymes viz. alkaline phosphatase, ceruloplasmin, superoxide dismutase and glutathione peroxidase. Thus, metallothionein plays a key role in metal metabolism during cadmium toxicity under nutritional stress conditions.
