    Liver lipids in Letterer-Siwe disease (1980)
    Springer
    European journal of pediatrics 135 (1980), S. 91-95

    Notes: Abstract A case of Letterer-Siwe disease in a thirteen-month-old girl with markedly swollen gums, an enlarged liver, and seborrhoic skin eruptions is reported. She died from pyopneumothorax in spite of treatment with prednisolone and vinblastine. Analysis of hepatic lipids showed that there was remarkable increase in free fatty acid, which is not seen in normal human liver. Cholesterol ester was also accumulated in the liver tissue. However, the concentrations of phospholipids and glycerides were low and lysophospholipid was found. It is assumed that there was increased intracellular lipolysis in the proliferating reticuloendothelial cells.

    Histiocytosis X with anterior mediastinal mass as its initial manifestation (1982)
    Springer
    Pediatric radiology 12 (1982), S. 84-85 
    Details
    ISSN: 1432-1998
    Keywords: Mediastinal mass ; Histiocytosis X ; Pulmonary changes

    Topics: Medicine
    Notes: Abstract This is a report of an unusual case of histiocytosis X whose initial manifestation was a large anterior mediastinal mass. Although the initial histology of the excised tumor suggested histiocytosis X, this was not confirmed until obvious bone and skin lesions developed later.

    Application of polylysine bound succinyl-NA to a membrane reactor (1976)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 18 (1976), S. 1761-1775

    Notes: The amide bond at N-6 in succinyl-NAD was found to be more stable than in former accounts. Succinyl-NAD was coupled on polylysine to give a new polymer derivative of NAD, which retained at least 85% of the initial coenzymic activity even after dialysis for one week. The polymer derivative of NAD could be applied to a membrane reactor containing alcohol dehydrogenase and lactate dehydrogenase and lactate was continuously produced in a half-life of ten days.

    Preparation of immobilized enzymes from acrylic monomers under γ-ray irradiation (1975)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Immobilized glucoamylase, invertase, and β-galactosidase were prepared by using 2-hydroxyethyl acrylate and dimethylacrylamide under γ-ray irradiation. In the case of 2-hydroxyethyl acrylate, the monomer-enzyme solution was changed to the gel by irradiation of less than 1.0 Mrad, but it was difficult to eliminate enzyme leakage from the gel. When leakage was eliminated by increased irradiation, the activities of the gels were very low. In the case of dimethylacrylamide, the monomer-enzyme solution was changed to a gel by irradiation of 1.0 Mrad; leakage could be eliminated by irradiation of 2.0 Mrad. This gel possessed very high activity. In the case of acrylic acid-sodium acrylate, the monomer-enzyme solution could not be changed to a gel. In preparing gels, high concentrations of enzyme protein had a tendency to obstruct gelation.

    Preparation of immobilized enzymes by N-Vinylpyrrolidone and the general properties of the glucoamylase gel (1974)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Immobilized glucoamylase, invertase, and β-galactosidase were prepared by using N-vinylpyrrolidone monomer (VP) under γ-ray irradiation. The enzyme-VP solutions were gelled by irradiation with 2.9 Mrad and the added enzymes were almost completely entrapped. Activity losses on entrapping were 55% for the VP-glucoamylase gel, and more than 90% in the case of VP-invertase and VP-β-galactosidase gels. No leakage of enzyme from these gels could be detected within 1 hr. The VP-glucoamylase gel was capable of hydrolyzing dextrin (mol wt 10,400) to glucose and the glucose equivalent was equal to that obtain able with native enzyme. The optimum temperature, heat stability, pH activity curve, and pH stability of VP-glucoamylase gel were slightly inferior to those of native enzyme, while Km was a little larger than that of native enzyme.
