    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 Unilateral lesions of the right superior colliculus (SC) were made in hamsters on the day after birth. In order to quantify the extent of abnormal innervation by left eye fibers in the diencephalon and midbrain, the left eye was removed on postnatal day 12 or 36, and after an appropriate survival time, the brains were stained for degenerating axons and axon terminals with the Fink-Heimer method. In additional cases, anterograde transport of 3H proline-leucine or horseradish peroxidase was used to assess left eye connectivity. In agreement with previous reports we found abnormal projections in the ventral nucleus of the lateral geniculate body (LGv), in the lateral posterior nucleus (LP) of the thalamus, and in the left SC (the ‘recrossing’ pathway). We also noted areas of abnormally heavy terminal fields arranged in patches in coronal sections in the dorsal nucleus of the lateral geniculate body (LGd). These patches arise from columns of dense innervation that are oriented along a rostral-to-caudal axis. If the right SC lesion was made large enough to diminish the recrossing pathway, retinofugal axons establish a significantly smaller distal terminal field in the left SC. In these cases, a corresponding increase in the size of terminal fields in all major proximal structures (LGd, LGv, LP, DTN) was observed. The sum of abnormal proximal growth (“compensatory sprouting”) was found to truly compensate for the distal loss of terminals. The evaluation of hamsters in which left eye connectivity was assessed at the age of 12 days revealed that lesion-induced patches of abnormal growth have already reached their full size by that time. These findings provide evidence for the ‘pruning -effect’ and demonstrate that retinofugal axons support a fixed number of terminal arborizations (the principle of ‘conservation of total axonal arborizations’).
