    On the enzymatic exchange of the sulphate group of the animal sulpho-mucopolysaccharides (1954)

    Notes: Zusammenfassung Es wird über Versuche zur Bestimmung des enzymatischen Umsatzes der Sulfatgruppe von Mucopolysacchariden mit Hilfe von S35-Sulfat berichtet. Letzteres ist in hohen Konzentrationen im Knorpel, in den Schleimhäuten, in der Intima aortae und in den Gewebsmastzellen nachweisbar. Das Ausmass dieser Sulfatfixierung kann entweder auf Grund von Organen isolierter Chondroitinschwefelsäure oder nach der Intensität der Schwärzung des autoradiographischen Bildes bestimmt werden. S35-Sulfat wird von dünnen Knorpelschnitten auch aus einer Lösung aufgenommen, womit das Studium des Umsatzes der Sulfatgruppenin vitro möglich ist. Durch Einfrieren, Homogenisieren oder Erhitzen des Knorpels auf 47°C wird seine diesbezügiche fermentative Aktivität zerstört. Der Umsatz der Sulfatgruppen wird besonders stark durch SH-Inhibitoren und auch durch Cortison gehemmt. Zusatz von Leberextrakt bewirkt eine hochgradige Stimulierung der Sulfatveresterung durch einen dialysierbaren und thermostabilen Aktivator.

    Demyelination of the mamillary bodies in alcoholism (1980)
    Springer
    Acta neuropathologica 50 (1980), S. 77-80

    Notes: Summary Four different regions of the brain (the mamillary bodies, vermis of the cerebellum, the dorsal and medial part of thalamus, and the quadrigeminal plate) from nine male chronic alcoholics and nine controls were analyzed for morphological and biochemical abnormalities. The mamillary bodies, in contrast to the other three regions, showed loss of myelinated fibers and decreased concentrations of cerebrosides, cholesterol and phospholipids, indicating demyelination. It is concluded that this kind of lesion is common in chronic alcoholism.

    Notes: [Auszug] The effects of felodipine were studied in the isolated rat portal vein. The smooth muscle of this vessel shows many similarities to that of the haemodynamically important small resistance vessels, including its pronounced dependence on extracellular [Ca2+] (refs 3-5).

    Respiratory depression after cimetidine reversed by physostigmine (1982)
    Springer
    Intensive care medicine 8 (1982), S. 153-154

    ISSN: 1432-1238
    Keywords: Cimetidine ; Respiratory depression ; Physostigmine reversal

    Notes: Abstract A state of severe respiratory depression and mental confusion after cimetidine administration in a patient with normal renal and hepatic function is described. The condition was reversed by a bolus dose of 2 mg physostigmine IV followed by a continuous infusion of 3.75 mg/h. The possibility of CNS side effects from cimetidine and the antagonism of physostigmine is emphasized, particularly in cases with stress ulcers related to intracranial disorders where sedation and respiratory depression have to be avoided.

    Iron-cemented sediment on lower continental slope off Cape Hatteras (1982)

    Notes: Abstract The textural, mineralogical, compositional and paleontological characteristics of an iron-cemented allochthonous sediment slab recovered from a zone of slumping between water depths of 2,100 and 2,350 m on the lower continental slope off Cape Hatteras are summarized. Results support interpretation of the sediment slab as the oxidized equivalent of pyrite-cemented Pleistocene to Recent sediment, an uncommon form of lithification in deep sea sediments. We propose that exposure of such slumped sediment slabs to seawater has produced an alteration sequence from pyrite-cement to iron oxide-cement. These observations extend the range of pyrite-cemented sediment initially reported from water depths between 4,770 and 4,950 m on the lower continental rise off Cape Hatteras.

    Notes: Zusammenfassung Die Versuche wurden an Hunden in Morphin-Urethan-older Morphin-Chloralose-Narkose durchgeführt. Es wird eine bestimmte Zahl von Carnaubawachskugeln von ca. 40 μ Durchmesser in die A. femoralis injiziert und untersucht, wie groß der Anteil an Kugeln ist, der auf der venösen Seite wieder erscheint. Danach fließen in der Mehrzahl der Versuche zwischen 0 und 30% der Durchblutung des gesamten Beines durch arterio-venöse Verbindungen von mehr als 40 μ Durchmesser. Bindet man die Pfote ab, so erscheinen nur sehr wenig Kugeln auf der venösen Seite. Nach Entnervung des Beines steigt die Durchblutung der a.v.A. stark an. Veritol vermindert sie. Durch intraarterielle Acethyl-cholin-Infusionen gelingt es nicht, die Durchblutung der arterio-venösen Anastomosen zu steigern. Abkühlung der Pfote vermindert, Erwärmung steigert die Durchblutung der arterio-venösen Anastomosen.

Kügelchen von etwa 30 μ Durchmesser werden dem arteriellen Blut beigemischt. Der Anteil der im venösen Blut wiedergefundenen Kugeln gilt als Maß für die Durchblutung der a.-v. A. Bei Hunden mit entnervten Carotis-Sinus und durchtrennten Vagi ist die Durchblutung deutlich geringer als bei intakten Kontrolltieren.

    Different patterns of phosphorus release from lake sediments in laboratory experiments (1982)

    Notes: Abstract The phosphorus release from surface sediments of eight lakes, mainly shallow lakes in agricultural areas, was studied in laboratory batch experiments with additions of acetate and/ or nitrate. The lake sediments could be separated into three categories. Some sediments did not release phosphorus under any conditions. The second category showed a high phosphorus release rate when acetate was added, in order to stimulate bacterial activity and oxygen consumption. The addition of nitrate, only, stabilized the redox conditions and prevented phosphorus release. This pattern followed the classical theories of Einsele and Mortimer. The third sediment category released phosphorus up to some level which remained constant throughout the experiment, and was independent of acetate and/or nitrate additions. Several extraction procedures and adsorption-desorption experiments were performed in order to characterize the sediment phosphorus and thus explain the different behaviours of the three sediment categories.
