    Notes: The pathway of bacteriophage λ head formation has been well characterized in vivo and in vitro (Hohn, Katsura & Hohn, 1977). First a petit λ particle consisting of a shell protein pE, a protein pNu3 and minor proteins, but lacking DNA, is formed. The pNu3-containing structure is then converted to a structure which does not contain pNu3, and which is capable of taking up and cutting the viral DNA. The purpose of this work is to determine the scaffold structure, formed by pNu3, by small-angle scattering techniques based on the known physico-chemical properties of pNu3-containing and pNu3-lacking particles (Künzler & Hohn, 1978). The scaffold is found to be inside the protein shell but less concentrated than the 130 Å radius core reported from electron micrographs.

    Description / Table of Contents: Zusammenfassung An einem auslesefreien Material von 275 Basaliomexcidaten wurde die Neubildung elastischer Fasern im Basaliomstroma mit Hilfe der Elastica-Färbungen (Orcein, Resorcin-Fuchsin) histologisch untersucht. In nahezu einem Drittel der Basaliome konnten neugebildete elastische Fasern im Stroma beobachtet werden. An Stellen, an denen eine Neubildung elastischer Fasern nachweisbar war, fanden sich ungewöhnlich zahlreich Fibroblasten und Mastzellen (Toluidin-Blaufärbung). Offensichtlich kommt es unter dem Einfluß des auswachsenden Basaliomstranges im Sinne einer dermo-epidermalen Interaktion 1. zu Mastzellvermehrung 2. zur Fibroblastenstimulierung 3. zur Neubildung elastischer Fasern. Die Beobachtungen legen den Schluß nahe, daß zwischen den genannten Befunden eine Wechselwirkung besteht. Als Folge der dermo-epidermalen Interaktion können die Fibroblasten (auch der Altershaut!) im Basaliomstroma so weit stimuliert werden, daß sie erneut die Fähigkeit erlangen, elastische Fasern zu bilden — eine Funktion, die sonst üblicherweise mit zunehmendem Alter weitgehend eingeschränkt ist. Die Befunde scheinen von Bedeutung unter dem Aspekt der “Verjüngung” menschlicher Altershaut — sie sind bisher jedoch nur von rein theoretischem Interesse.
    Notes: Summary From 275 specimens of all sorts of basal cell epitheliomas the new formation of elastic fibers was histologically investigated by means of selective elastic tissue stains such as orcein and resorcinfuchsin. In nearly one third of the basal cell epitheliomas newly formed elastic fibers could be observed in the stroma. In places where a new formation of elastic fibers was demonstrated fibroblasts and mast cells (toluidine blue stain) were unusually numerous. Apparently the influence of the growing tumor masses of basal cell epitheliomas leads to a dermo-epidermal interaction in the form of 1. increase of mast cells 2. stimulation of fibroblasts 3. new formation of elastic fibers. The observation suggest that there exists a relationship between the above noted findings. Due to the dermo-epithelial interaction (even in senile skin) in the stroma of basal cell epithelioma fibroblasts can be stimulated to such a degree that they regain the ability to produce elastic fibers—a function which usually is greatly diminished with increasing age. The findings seem to be important from the view point of rejuvenation of aging human skin.
