    Notes: Summary In patients with vestibular disturbances the examination of vestibulospinal reflexes belongs to the normal neurotological test-battery. We use Romberg's test, Unterberger's test and WOFEC (walk on floor eyes closed). On one hand, these tests usually are analysed visually and therefore are quoted subjectivly. On the other hand, they are often used by patients to simulate pathologic test-results or aggravate weak pathologic findings. The computer analysis of an electronically performed Romberg test may help to gain more objectivity. It can be shown, that analysis of body motion itself is less effective than the analysis of variations of its velocity.

    Description / Table of Contents: Summary Male rats were subjected to acute stress by making them swim, prior to whichMetopiron (adrenostatic) was given, or unilateral adrenalectomy in addition had been done. A pronounced loss of lipoid occurred in the adrenal cortex, whereas the thyroid showed chiefly inactivation. The anterior lobe of the pituitary disclosed marked change only in the „thyrotropic“ system; after only seven hours of total experimentation there were homogenizations of the type „thyroidectomy cells“. From the studies it was concluded, that TSH and ACTH were formed in the “thyrotropic system” of the rat pituitary. Both substances, however, showed a different mechanism of secretion: whereas TSH was secreted in increased amounts in thyroxin deficiency, it was not stored in the anterior lobe. On the other hand, ACTH under conditions of stress was formed in increased amounts, stored and secreted. This was reflected in the variable content of granules in the thyrotropic system.
    Notes: Zusammenfassung Männliche Ratten werden akuten Belastungen durch Schwimmen unterworfen, nachdem vorher das Adrenostaticum Metopiron gegeben oder zusätzlich einseitig adrenalektomiert worden war. In der Nebennierenrinde kommt es zu ausgeprägten Lipoidverlusten, während an den Schilddrüsen überwiegend Inaktivierung zu beobachten ist. Der HVL zeigt ausgeprägte Formwandlungen nur im „thyreotropen“ System, schon nach 7stündiger Gesamtversuchszeit sind Homogenisierungen vom Typ der „Thyreoidektomiezelle“ zu beobachten. Aus den Versuchen wird geschlossen, daß TSH und ACTH im „thyreotropen“ System der Rattenhypophyse gebildet werden. Beide Wirkstoffe zeigen aber einen differenten Sekretionsmechanismus: Während TSH im Thyroxin-Mangelzustand zwar erhöht sezerniert, aber im HVL nicht gespeichert wird, wird ACTH unter Stressbedingungen gleichzeitig erhöht gebildet, gespeichert und sezerniert, was sich im unterschiedlichen Granulagehalt des thyreotropen Systems widerspiegelt.

    Notes: Summary Representative arable soils from Hesse were investigated for their contents of fixed NH4 + and EUF-extractable potassium in the rooting zone. Alluvial soils were found to be rich in fixed ammonium and low in EUF-extractable potassium, while soils of basaltic origin were low in fixed ammonium and rich in EUF-extractable potassium. A negative correlation (r=0.79*) was found between fixed NH4 + and EUF-extractable soil K+. The content of fixed NH4 + in the soil profile showed considerable and significant changes during the growing season, which finding is supposed to be due to NH4 + uptake by the crop.

    Description / Table of Contents: Zusammenfassung Posturographische Messungen auf Plattformen mit piezoelektrischen Druckfühlern sind ein inzwischen verbreitetes Verfahren bei der Gleichgewichtsprüfung. Die elektronische Auswertung einer solchen Untersuchung ist sehr aufwendig, jedoch unerläßlich für eine differenzierte Beurteilung. Voraussetzung für die Auswertung und die Beurteilung ist die Darstellung der Körperschwerpunktschwankungen bei Gesunden. An einem großen Kollektiv wurden die intra-und interindividuellen Unterschiede beim Romberg-Test anhand einer quantitativen Auswertung aufgezeigt und diskutiert.
    Notes: Summary Posturographic measurements on platforms with piezoelectric recording techniques are a common method in the examination of balance. Its electronic analysis requires in-depth efforts, but is necessary for an exact evaluation. Precondition for the analysis and the evaluation is the description of the sway path of the center of gravity in healthy subjects. Intra-and interindividual differences in the Romberg-test are evident and under discussion from a wide selection of normal individuals by means of a quantitative evaluation.

    Notes: Äthyl-äthoxy-aluminiumchlorid bildet ein Dimeres, das über Chloratome assoziiert ist, und ein Trimeres, bei dem die Assoziation über die Sauerstoffatome der Äthoxygruppen erfolgt. Beide Eigenkomplexe stehen miteinander im temperatur- und konzentrationsabhängigen Gleichgewicht. Sie unterscheiden sich durch ihre IR-Spektren, ihr Reaktionsvermögen und ihre Dichte. Bei der Herstellung aus Diäthylaluminiumchlorid und Äthylalkohol entsteht zunächst das Dimere, welches sich spontan in das Trimere umwandelt. Die Umwandlungsenthalpie beträgt  -  2,15 kcal/Mol.
