    Description / Table of Contents: Zusammenfassung Wir haben im Urin von insgesamt 350 gesunden und kranken Kindern die Aktivität von 7 Enzymen und deren Isoenzymeigenschaften untersucht. Bei Neugeborenen ist die höchste Aktivität der alkalischen Phosphatase, der Glutamin-Oxalacetat-Transaminase und des Lysozyms am 1. und 2. Tag nach der Geburt nachzuweisen. Bei mehr als der Hälfte der Kinder mit akuter Glomerulonephritis sind die Aktivitäten der alkalischen Phosphatase, der Glutamin-Oxalacetat-Transaminase und der Lactat-Dehydrogenase pathologisch erhöht und gehen im Heilungsstadium allmählich auf normale Werte zurück. Auch bei orthostatischer Proteinurie sind die Aktivitäten für diese Fermente sowie für β-Glucuronidase erhöht. Demgegenüber sind bei Kindern mit nephrotischem Syndrom die Fermentaktivitäten meistens tiefer. Pathologisch erhöhte Enzymaktivitäten bestehen ferner bei Kindern mit Leukämie, Neuroblastom, Pneumonie, Hyperthyreoidismus, Hyperbilirubinämie, Asthma bronchiale und Diabetes mellitis. Zwischen den Aktivitäten eines bestimmten Ferment im Urin und im Serum besteht keine Korrelation.
    Notes: Abstract The determination of serum enzyme levels has been increasingly used in diagnosis of children's diseases. However, urinary enzymes have been little studied and many problems remain to be elucidated. As a possible guide to differential diagnosis and prognosis of children's diseases, the urinary enzyme levels were determined in 350 children with and without diseases. The urinary levels of lysozyme (MG=14,000), amylase (MG=45,000), alkaline phosphatase (AP, MG=100,000), glutamate transaminase (GOT, MG=100,000–120,000), lactic dehydrogenase (LDH, MG=140,000), leucine aminopeptidase (LAP, MG=300,000) and β-glucuronidase (MG=300,000) were measured simultaneously in each child. In the neonatal period the highest activities of alkaline phosphatase, glutamate transaminase and lysozyme were observed on the first and second day after birth. The urinary levels of alkaline phosphatase, glutamate transaminase and lactic dehydrogenase were elevated in more than half of the cases in the acute phase of glomerulonephritis, and gradually decreased down to normal levels during recovery. High levels of alkaline phosphatase, glutamate transaminase, lactic dehydrogenase and β-glucoronidase were found in some cases of orthostatic proteinuria. In nephrosis, however, the enzyme activities were mainly low. Abnormally high enzyme levels were observed in leukemia, neuroblastoma, pneumonia, hyperthyreoidism, hyperbilirubinemia, bronchial asthma, and diabetes mellitus. No correlation was found between the enzyme activities in the urine and serum.

    Description / Table of Contents: Zusammenfassung Es wurden Urin-, Serum-und Nierenenzyme von Wistarratten nach experimenteller Nierenschädigung untersucht und die Aktivitäten von 6 Urinenzymen (Lysozym, alkalische Phosphatase, Glutamin-Oxalacetat-Transaminase, Lactat-Dehydrogenase, Leucin-Aminopeptidase und β-Glucuronidase) bestimmt und gleichzeitig auch Isoenzyme (alkalische Phosphatase, Glutamin-Oxalacetat-Transaminase und β-Glucuronidase) untersucht. Wir finden im Aktivitätsverlauf der Urinenzyme und der Isoenzyme deutliche Unterschiede zwischen den Ratten, denen Nephrotoxin und denen Aminonucleosid injiziert wurde. Bei den Isoenzymen der verschiedenen Urinenzyme war bei beiden Gruppen ein deutlicher Unterschied zu beobachten. Das Muster der Isoenzyme ist bei Urin-und Nierenfermenten ähnlich, weicht aber von dem der Serumfermente ab.
    Notes: Abstract The origin of urinary enzymes is obscure. We therefore determined the levels of urinary, serum and kidney enzymes (lysozyme, amylase, alkaline phosphatase, glutamate transaminase, lactic dehydrogenase, leucine aminopeptidase and β-glucuronidase) and isozymes (alkaline phosphatase, glutamate transaminase, leucine aminopeptidase and β-glucuronidase) in Wistar rats with nephrotoxin nephritis or aminonucleoside nephrosis. The urinary enzyme activities varied in several ways in rats with nephrotoxin nephritis and with aminonucleoside nephrosis. A significant difference in the isozymes was found in the two groups. The isozyme-pattern of urinary enzymes resembles that of kidney enzymes, but not that of serum enzymes. These findings indicate that the urinary enzymes are mainly formed by destruction and renewal of renal tissue.

    Notes: Surface-reaction film-formation technology of epitaxial Si and polcrystalline silicon using free-jet molecular flow is proposed. High-rate (∼0.5 μm/min or higher) growth of homoepitaxial Si films with high crystallographic perfection has been achieved at temperatures as low as 600 °C without the chemical by-product deposition on the inner surface of the reaction chamber. This result also implies that this system has the cleaning-free function. The film-formation mechanism appears to be dominated by the chemical reaction on the substrate surface without the vapor phase reaction.
