    Notes: Summary Circulating immune complexes by fluid phase Clq binding assay, complement components and anti-immunoglobulin levels were studied in sera of 35 patients with rheumatoid arthritis (RA). In 23 of the 35 sera (65.7%), circulating immune complexes were positive, and the mean±SD of Clq binding activity (ClqBA), 44.5±19.4%, was significantly high compared to that of healthy persons, 17.4±8.2%. Antigenic determination of complement components revealed that Clq, C3, C5, C9, factor B and Cl esterase inhibitor (CIINH) were significantly high in sera of RA, but C4 and properdin were not. The disease activity correlated with ClqBA, IgG- and IgM-anti-immunoglobulins, C9 and serum IgG. On the other hand, ClqBA correlated with both IgG- and IgM-anti-immunoglobulin levels but not with complement components.

    Notes: Summary A protein-bound polysaccharide from mycelia ofCoriolus versicolor PS-K, clinically used as an immunomodulator, has been shown to restore the decreased cellular immune response and to exhibit host-mediated antitumor activity. In this experiment, PS-K was found to increase serum complement level in guinea pig and in human without malignancy, when hemolytic assay of complement was performed using sensitized sheep erythrocytes for the classical pathway activity and unsensitized rabbit erythrocytes for the alternative pathway activity. Assay of complement components revealed increase in C3 level in guinea pig, but no significant changes in Clq, C4, C3, properdin, C3 activator, and C $$\bar 1$$ -inhibitor in human, while C5 and C9 were depressed. Conversion ofβ1C toβ1A was observed in the 7th day's plasma of these patients by crossed immunoelectrophoresis. Biosynthesis of guinea pig C3 was accelerated by administration of PS-K, but that of C4 was not affected. These evidences suggested that PS-K might potentiate immune response of the host by elevating serum complement level, in addition to the activation of the complement system.

    Notes: Summary Experimental disseminated intravascular coagulation (DIC) was induced by sustained infusion of endotoxin into the femoral vein in rats. The severity of DIC was determined with reference to various parameters, such as fibrinogen and fibrin degradation products (FDP), prothrombin time (PT), partial thromboplastin time (PTT), platelet count, and number of renal glomeruli having fibrin thrombi. Experimental DIC could be induced by a 4-h sustained infusion of endotoxin in a dose of 100 mg/kg. The DIC induced in rats showed a close resemblance to human DIC as judged from such changes as an elevation in FDP, prolongation of PT and PTT, depression in fibrinogen and platelet count, and increase in glomeruli having fibrin thrombi. This experimental model has an advantage in that the severity of DIC can be determined by measuring various parameters. It will be of use in the studies aimed at the establishment of a therapy for DIC as well as in the studies on DIC in rats.

    An autopsy case of acute porphyria with a decrease of both uroporphyrinogen I synthetase and ferrochelatase activities (1984)

    Notes: Summary An autopsy case of a 37-year-old woman with acute porphyria is reported. The patient began to complain of severe menstrual pains, and later developed serious peripheral neuropathy and various autonomic nervous symptoms. The autopsy revealed a marked loss and degeneration of axons and myelin sheaths in the peripheral nervous system (PNS), and prominent central chromatolysis of the spinal anterior horn cells. The predominant process of the peripheral neuropathy appeared to be axonal degeneration. Biochemical analysis showed a marked increase of delta-aminolevulinic acid (ALA), porphobilinogen, uroporphyrin, and coproporphyrin in the urine, and an increase of coproporphyrin and protoporphyrin in the stools and blood. In the analysis of the enzymatic activities of the liver and bone narrow, the activity of ALA synthetase (ALA-S) was markedly increased, and the activities of both uroporphyrinogen I synthetase (URO-S) and ferrochelatase were decreased. It was characteristic in this case that the enzymatic abnormalities found in both acute intermittent porphyria (AIP) and variegate porphyria (VP) coexisted. Biochemical analysis of the sciatic nerve showed an increase of ALA-S activity and a decrease of both URO-S and ALA dehydrase activities. This was the first report that indicated the presence of abnormal activities of the heme biosynthetic enzymes in the peripheral nerves of porphyric patients. The possibility was discussed that these enzymatic abnormalities of the heme biosynthesis in the peripheral nerve itself might be strongly related to the pathogenesis of the porphyric neuropathy.

    Description / Table of Contents: Summary 1. The authors studied about drying shrinkage of hardened cement paste specimens, which were different in physical properties, by curing at various temperatures ranging from normal to high temperature. 2. Water vapour absorption test and drying shrinkage test were made on the specimens which were same in size, mixing proportion and curing conditions. 3. By research cancerning mechanism and some causes of the drying shrinkage of hardened cement paste, the authors were able to define the following relations. a) Drying shrinkage is proportional to the strength of capillary tension. b) Drying shrinkage is proportional to the amount of evaporable water held at equilibrium in unit volume of hardened cement paste. c) Drying shrinkage is inversely proportional to the dynamic Young's modulus. 4. The shrinkage of hardened cement paste due to the escape of interlayer water in its gelatinous material is probably caused by very low relative humidity.
    Notes: Résumé 1. Les auteurs ont étudié le retrait au séchage d'éprouvettes de pâte de ciment durcie, aux propriétés physiques différentes, par conservation à différentes températures, des températures normales jusqu'aux températures élevées. 2. Les essais d'absorption de vapeur d'eau et de retrait au séchage ont été faits sur des éprouvettes ayant les mêmes dimensions, le même dosage, et conservées dans les mêmes conditions. 3. Des recherches sur le mécanisme et quelques-unes des causes du retrait au séchage de la pâte de ciment durcie ont permis aux auteurs de définir les relations suivantes: a) le retrait au séchage est proportionnel à la valeur de la pression capillaire; b) le retrait au séchage est proportionnel à la quantité d'eau évaporable maintenue à l'équilibre dans le volume unitaire de la pâte de ciment durcie; c) le retrait au séchage est inversement proportionnel au module d'élasticité dynamique de Young. 4. Le retrait de la pâte de ciment durcie dû au départ de l'eau interstitielle à l'état de gel est probablement provoqué par de très faibles humidités relatives.

    Increase of δ-Aminolevulinic Acid Dehydratase (ALAD) in rat erythrocytes in lead poisoning (1983)

    Notes: Abstract The well known fact that the activity of δ-aminolevulinic acid dehydratase (ALAD: EC 4.2.1.24) is reduced in red cells of animals with lead poisoning was found to be upset, by using a modified method of Gibson's original procedure, for determination of activated ALAD activity. The modified method involves addition of 0.2 mM Zn2+ and then preheating the enzyme solution at 60° C for 5 min before following Gibson's original procedure. With this methodological modification, the ALAD activity of erythrocytes of rats poisoned with lead was found increased. Furthermore, the enzyme was purified from the peripheral blood of lead-poisoned rats. ALAD protein in peripheral blood was also determined by single radial immuno diffusion using rabbit anti-serum raised against rat liver ALAD. As the result, the ALAD activity obtained from the modified method was found to be directly proportional to the absolute amount of enzyme proteins determined both by chemically and immunochemically. The modified method for measuring true ALAD content in blood cells in lead poisoning is more reliable than previous ones.
