In women employed in an industrial plant in direct contact with epoxide resins and their hardeners, the following biochemical parameters were determined in blood: total protein, seromucoid, haptoglobin, hemoglobin variants, methemoglobin, alpha1-inhibitor of trypsin, lactate dehydrogenase, aspartate and alanine aminotransferases, alkaline and acid phosphatase, gamma-glutamyl transpeptidase, leucylaminopeptidase, and alanine aminopeptidase. Depending on duration of work, Hb A2 fraction and lactate dehydrogenase increased significantly, and aspartate aminotransferase, acid and alkaline phosphatase activities decreased. In pregnant women, leucylaminopeptidase activity and isozyme of placental alkaline phosphatase were decreased.

A protein that has 2 subunits with molecular weight of 35,000 and 23,000 was detected in serum of cattle with hepatic lipidosis (fatty liver). The protein was purified from serum obtained from a cow with fatty liver, and was identified as haptoglobin, which is known to have hemoglobin-binding capacity and to be an acute-phase protein. To assess the relevance of haptoglobin in fatty liver, cattle were classified in 3 groups (healthy control, haptoglobin-positive, and haptoglobin-negative); liver triglyceride content and several serum biochemical variables were evaluated for the 3 groups. Compared with the control and haptoglobin-negative cattle, haptoglobin-positive cattle had significantly (P less than 0.01) higher liver triglyceride content, serum bilirubin concentration, and aspartate transaminase activity. Serum haptoglobin concentration was high in slaughter cattle (27 of 40 cattle tested), particularly in cows (20/28).

The venom of the South American rattlesnake Crotalus durissus terrificus was first reported to have mainly haemolytic and neurotoxic physiopathological activities. Later studies demonstrated the systemic myotoxic action of the venom, characterized by the release of myoglobin from damaged skeletal muscle into serum and urine, and a recent report ruled out the presence of intravascular haemolysis in 3 patients, one child and 2 adults. The present paper describes the clinical-laboratory evolution of 10 children bitten by C. durissus terrificus; 2 developed acute renal failure and one died. The myotoxic activity of the venom was evaluated by measuring serum lactic dehydrogenase, creatine kinase and aspartate aminotransferase, by detection of myoglobin in serum and urine, and by muscle biopsy. Haemolytic activity was evaluated by serial measurements of serum haemoglobin and haptoglobin and by detection of urine haemoglobin. We conclude that the signs and symptoms exhibited by patients bitten by C. durissus terrificus are due only to the myotoxic and neurotoxic action of the venom. The only patients with major morbidity were those who initially received subcutaneous antivenin and did not receive definitive antivenin therapy until later.

The synthetic factor based on determinations of 10 parameters in sera of patients with ovarian carcinoma, was constructed. The factor was found to be useful in evaluation of the effectiveness of the cytotoxic treatment and in indication of the recurrence of the malignancy. Reduction of the number of biochemical markers to five (haptoglobin, seromucoid, lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase), according to significance of particular markers in the laboratory diagnostics of ovarian cancer did not affect the diagnostic sensitivity of the synthetic factor.

We investigated the relation between haptoglobin (Hp) phenotypes and serum levels of various biochemical markers after myocardial infarction in 496 patients. In 122 subjects selected on the basis of short delays until hospitalization, patients with Hp 2-2 had higher cumulated creatine kinase activity than patients with Hp 1-1, or Hp 2-1 (P less than 0.05), as well as higher myoglobin concentrations (P less than 0.02) 12 to 28 hours after admission. Comparison of serum enzyme activities in the remaining 374 patients confirmed that Hp 2-2 patients had significantly higher total creatine kinase, creatine kinase isoenzyme MB fraction, aspartate aminotransferase, and lactate dehydrogenase peak levels. Complications of left ventricular failure were more frequent in these patients (P = 0.05). Our results suggest that Hp 2-2 patients have more severe myocardial infarctions than Hp 1-1 and Hp 2-1 patients, However, no difference in the distribution of haptoglobin phenotype was found between patients who had a myocardial infarction and healthy subjects, indicating that Hp 2-2 does not predispose to the occurrence of infarction.

Three hundred and two consecutive patients who had undergone cardiac operation for various cardiac lesions were studied prospectively to evaluate the incidence, risk factors, and the associated mortality of postoperative hyperbilirubinemia after cardiopulmonary bypass. Concentrations of the serum total (conjugated and unconjugated) bilirubin, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, alkaline phosphatase, albumin, globulin, and serum haptoglobin were measured before the operation and again on the first, second, and seventh postoperative days. Postoperative hyperbilirubinemia was defined as occurrence of a serum total bilirubin concentration of more than 3 mg/dl in any measurement during the postoperative period. Logistic regression was done to identify possible risk factors for postoperative hyperbilirubinemia. Overall incidence of postoperative hyperbilirubinemia was 35.1%; the incidence of postoperative hyperbilirubinemia was higher in patients whose valves were replaced with mechanical prostheses than in those without prostheses (p < 0.00001). In patients with postoperative hyperbilirubinemia, 70% of the increase of total bilirubin on the first postoperative day came about from an increase in unconjugated bilirubin. Serum haptoglobin decreased significantly at the same time (p < 0.01). Development of the postoperative hyperbilirubinemia was associated with a higher mortality (5.6% versus 0.5%, p < 0.01) and higher frequency of use of intraaortic balloon counterpulsation, especially for patients in whom the highest postoperative total bilirubin occurred after the first 2 days. The numbers of valves replaced, preoperative right atrial pressure, and preoperative total bilirubin concentration are the significant risk factors that, in combination, correctly predict the occurrence of postoperative hyperbilirubinemia in 80% of the patients. We concluded that postoperative hyperbilirubinemia results mainly from an increase in unconjugated bilirubin and is associated with higher mortality, especially for patients in whom highest postoperative total bilirubin occurred late after operation. Patients with the higher preoperative right atrial pressure and total bilirubin level who then underwent multiple valve replacement procedures are at greater risk for development of postoperative hyperbilirubinemia.

This study was undertaken to determine the effects of long-distance running on serum bilirubin fractions. Thirteen male ultramarathon runners participating in a 100-km race volunteered for the study. Venous blood samples were obtained shortly before and immediately after the race. Decreased serum haptoglobin levels (-66%) indicated the presence of hemolysis. After accounting for plasma-volume loss, significant post-race increases were found for creatine kinase (+20-fold), creatine kinase-MB (+252%), alanine aminotransferase (+42%), aspartate aminotransferase (+193%), gammaglutamyl transpeptidase (+56%), and glutamate dehydrogenase (+58%) serum activities, suggesting that running causes alterations of both muscle and liver tissues. Serum concentration of total bilirubin was significantly elevated (+106%) following the race, with changes corresponding to both unconjugated (+96%) and conjugated esters (+283%) of the pigment and significant increases in the ratio of esterified to total bilirubin. Our data show that long-distance running causes increases in the different serum bilirubin fractions which can be accounted for both hemolysis and hepatic disturbances.

The U2 linkage group of horses includes the genes albumin (ALB), vitamin D binding protein (GC), mitochondrial glutamate oxaloacetate transaminase 2 (GOT2), and haptoglobin (HP) which are found on two human chromosomes, namely, 4 (HSA 4) and 16 (HSA 16). Likewise these genes are also found on two different chromosomes in mice, rats, and cattle. Chromosome painting demonstrated that only horse chromosome 3 (ECA 3) hybridized with whole chromosome paints for both HSA 4 and HSA 16. This indicated that the equine U2 linkage group occurs on ECA 3, spanning the centromere. This technique will be useful to study the chromosome rearrangements associated with speciation of the genus Equus.

The stage of human African trypanosomiasis (HAT) is important to define precisely as far as it is directly related to the type of treatment used. The beginning of the neurological involvement is difficult to find out because there is no known specific clinical or biological sign. This study is trying to look for a precise marker and has been realized in Congo. 70 subjects with parasitologically confirmed HAT and 70 controls are included. The stage of HAT is determined according to the classical definition on the field using the cerebrospinal fluid (CSF) cell count: less than 5 cells/microliters for the first stage (P1), more than 5 cells/microliters for the second stage (P2). The blood analysis has included: glucose, urea, creatinine, sodium, potassium, calcium, chloride, phosphorus, uric acid, total bilirubin, unconjugated bilirubin, total cholesterol, triglycerides, total proteins, aspartate aminotransferase, alanine aminotransferase, creatinine phosphokinase, alkaline phosphatase, gamma-glutamyltransferase, immunoglobulins M and G, C3c fraction of complement, transferrin, seromucoid alpha 1, haptoglobin and albumin. In CSF we have analyzed IgM, IgG, protein levels and the bloodbrain barrier (BBB) impairment. The comparison between the subjects and their controls, the subjects in P1 and in P2, the CSF cell count and the other CSF alterations show the interest of the IgM level in CSF and the BBB impairment to identify subjects in P2. However there is a low gradation in the biological disturbances and not a precise threshold point. Nevertheless it seems reasonable to raise the CSF cell count level to 20 cells/microliters to define the beginning of the nervous involvement.
