    Notes: Abstract Optical reflection measurements are described as a new and simple technique to measure thicknesses and thickness changes of ultrathin organic overlayers on inorganic support. The prime advantages are high sensitivity in thickness measurements (0.1–1 Å), applicability under varying environmental conditions, nondestructiveness, applicability on different supports and high time resolution. These features are assessed theoretically and experimentally studying Langmuir-Blodgett films on SiO2 and Au supports. These films, in this work prepared with the model compound arachidic acid, provide the salient feature of well-defined thicknesses in integer multiples of 26.7 Å. Application of the technique in thermodesorption experiments reveals distinguished binding states with binding energies (73–110 kJ/mol) depending on the counterion (Mg2+ or Cd2+) used in preparing the films and ratios of different states depending on thickness. The binding energy for the main component of multilayers (73 and 81 kJ/mol) with thickness larger than 100 Å is comparable to the heat of evaporation of bulk fatty acids. In addition an analytic expression between layer thicknesses and reflection is derived from the Fresnel equation.

    Description / Table of Contents: Abstract E. Grosshans and L. Marot first described blaschkitis in 1990 as a linear inflammatory dermatitis following lines of Blaschko in an adult patient. We report another case which occurred in a 38-year-old woman who developed an extensive, linear, erythematosquamous dermatitis involving the face, all limbs and the trunk. The patient's serum tested positive for antinuclear antibodies at a dilution of 1:640. The lesions regressed spontaneously within 4 weeks. Blaschkitis is a distinct entity which corresponds neither to a known inflammatory dermatitis in the lines of Blaschko nor to an hamartoma nor to an X-linked disease. Cutaneous antigenic mosaicism, the expression of which might be induced by a viral infection, could trigger this localized inflammatory T-cell response. This hypothesis relates blaschkitis to other cutaneous autoimmune diseases, as does the presence of antinuclear antibodies. We therefore suggest renaming this type of inflammatory dermatitis Grosshans-Marot disease in honour to the dermatologists who first described the entity.
    Notes: Zusammenfassung Die “Blaschkitis”, eine blaschkolineäre Dermatitis im Erwachsenenalter, wurde von E. Grosshans und L. Marot 1990 erstmals als Entität beschrieben. Wir berichten von einem weiteren Fall einer “Blaschkitis” bei einer 38-jährigen Patientin ohne Vorerkrankungen, die an Kopf, Hals, Armen, Beinen und extremitätennahen Rumpfbereichen blaschkolineäre erythematosquamöse Läsionen entwickelte. Es fanden sich antinukleäre Antikörper mit einem Titer von 1:640. Spontane Abheilung trat innerhalb von 4 Wochen ein. Bei der “Blaschkitis” handelt es sich weder um eine blaschkolineäre Variante einer bekannten Dermatose noch um eine hamartomatöse Fehlbildung noch um einen X-chromosomal-dominanten Gendefekt. Ein Mosaik kutaner Antigene mit Expression im Laufe des Lebens (z. B. virusinduziert) könnte zu dieser blaschkolineären T-lymphozytären Entzündungsreaktion führen. Diese Theorie rückt die blaschkolineäre Dermatitis im Erwachsenenalter in die Nähe der Autoimmunerkrankungen, ebenso die gefundenen antinukleären Antikörper. Nachdem es sich bei der “Blaschkitis” um eine eigenständige Entität handelt und verschiedene Namengebungen sich international nicht durchsetzen konnten, möchten wir vorschlagen, sie nach den Erstbeschreibern Morbus Grosshans-Marot zu benennen.

    Notes: Summary Syrian golden hamsters were implanted with fixed or moveable stimulating electrodes aimed at the superior colliculus (SC). Behavior was observed in response to trains of 0.1 ms pulses at 200 Hz while the animals were moving freely in an open arena or in their home cages. At threshold stimulating currents, the responses consisted almost entirely of freezing or contraversive turning, which occurred in two forms: fast turns, resembling orienting movements to sunflower seeds, and slow turns that were smooth and continuous. Other responses, including head raising and lowering, ipsiversive turning and backing movements were seen occasionally. Increasing the stimulating current usually gave a variety of responses, including circling movements, prolonged freezing, ipsilateral movements and running escape behavior. The sites in SC giving freezes at threshold tended to be located superficially (SO and above), or deep (SGP and below), while sites giving turns were in the intermediate layers. Most freeze sites occurred in the rostro-medial SC that represents the upper visual field, while turn sites occurred predominantly in caudo-lateral SC. Apart from the turns, most of the stimulated responses resembled natural defensive behavior, supporting the view that SC in rodents plays a role in organizing responses to predators, as well as in orienting behavior.

    Notes: Abstract A simple, non-invasive, non-radioactive liverfunction test is proposed. After an oral dose of 3 mg 15N-methacetin per kilogram body mass, the kinetics of 15N excretion via urine were characterized by the quotient of the amounts of 15N excreted in two successive urine samples (Q value). The stable nitrogen isotope 15N was found to be an excellent and easily detectable indicator of the sum of all methacetin metabolites present in urine. Alterations in the nature or ratio of methacetin metabolites due to liver diseases could not be found. From the investigation of 11 men, 3 pregnant women and 15 children, a clear difference was observed in Q values of healthy persons and patients suffering from liver-cell-activity diseases. The discriminating power of our new liver-function test is shown to be equivalent to that of the 14CO2 breath test.
