    Notizen: Aqueous extracts of select members of the Basidiomycetes and Deuteromycetes (Fungi Imperfecti) were evaluated for the presence of shared allergenic determinants using skin prick and radio-allergosorbent test (RAST) inhibition. Twenty adults with perennial symptoms of rhinitis, with or without asthma, were skin-prick tested with six species of Deuteromycetes and seven species of Basidomycetes. Positive weal-and-flare reactivity to Pleurotus ostreatus was associated with Alternaria alternata, Fusarium solani and Epicoccum purpurescens. Positive skin reactivity to Calvatia cyathiformis was also associated with A. alternata and F. solani. Coprinus quadrifidus was associated only with F. solani, and Psilocybe cubensis was only associated with Aspergillus fumigatus. No other skin test associations were demonstrated. For every allergen tested by RAST inhibition, significant dose-dependent homologous inhibition was demonstrated. Although the ability of an individual heterologous extract to inhibit the direct RAST varied, inhibition was generally minimal. In the most extreme example, no heterologous allergen inhibited the A. alternata RAST. However, the Armillaria tabescens RAST was inhibited 52·6%, 38·1% and 25·1% by A. fumigatus, E. purpurescens, and Penicillium notatum, respectively, suggesting significant cross-reactivity. These results suggest that, although shared allergenic determinants exist between select species of Basidiomycetes and Deuteromycetes, crossreactivity is minimal and its clinical significance is not clear. These data confirm that for reliable diagnosis of fungal allergy, representatives of both major groups must be used.

    Notizen: Aqueous extracts of Fusarium solani and other members of the Fungi Imperfecti were evaluated for the presence of common antigenic/allergenic determinants using skin-prick testing, radio-allergo-sorbent test (RAST) inhibition, and immunoelectrophoretic methods. Prevalence of skin reactivity in forty-four atopic individuals, tested with commercially available fungal extracts, ranged from 27.3% for Alternaria tenuis to 6.8% for Penicillium notatum. No specific patterns of reactivity emerged from statistical analyses of skin test data. In contrast, RAST inhibition demonstrated common allergenic determinants. P. notatum and Aspergillus glaucus inhibited F. solani RAST by 79% and 84%, respectively. This was supported by crossed line immunoelectrophoresis; both P. notatum and A. glaucus had antigenic determinants in common with F. solani. Collectively, these studies suggest that F. solani, P. notatum, and A. glaucus have several common antigenic/allergenic determinants.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Wenn von dem Hinterbein des Salamanders die Fibula entfernt worden ist, ohne die übrigen Knochen zu verletzen und der untere Theil des Beines später in der Tibia abgeschnitten ist, bringt der regenerirte Theil einen ganzen Fuß mit fünf Zehen sowie das distale Ende der Fibula hervor, das allein von Material gebildet wird, welches aus dem abgeschnittenen Ende der Tibia hervorgesprosst ist.
    Notizen: Summary When from the hind-leg of a salamander, the fibula is removed without injuring the remaining bones and the leg is later cut off through the tibia, the new part that regenerates will produce a whole foot with five toes, and also the distal end of the fibula. These structures are formed from material proliferated by the cut-end of the tibia alone.

    Notizen: Abstract Aqueous cotton dust extracts (ACDE) stimulated production of cyclic adenosine monophosphate (cAMP) in normal human peripheral blood mononuclear leucotytes (MNL). This response was not due to prostaglandin production by monocytes or platelets in the cell preparation nor to stimulation of the beta-adrenergic or H2 receptors; however, desensitization experiments indicated that the response may be receptor mediated. The possible involvement of such receptor desensitization in byssinosis pathogenesis is discussed.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Wird das erste Bein des Flußkrebses durch Abbrechen des Gelenkes von diesem an entfernt, so wird kein Muskel verletzt und die Muskeln für das neue Bein werden durch Zellproliferation seitens des Ektoderms gebildet. Obgleich der Nerv bei stattfindender Autotomie (freiwilliger Abschnürung des Gliedes) zerrissen wird, so werden die Bildungszellen für den neuen Nerven (oder zum mindesten für die neue Nervenscheide) gleichfalls von sich differenzierenden durch Proliferation entstandenen Ektodermzellen gebildet. Beim Einsiedlerkrebs werden die Muskeln des neuen Beins gleichfalls durch Ektodermzellen gebildet. Wenn beim Einsiedlerkrebs das Bein durch Abbrechen des Gelenkes entfernt wurde, so ist die Basis der Länge nach gespalten, so daß der Nerv geteilt, der Länge nach getrennt wird. Dann erscheinen oft zwei neue Beine, jedes mit einem Stumpfteil des alten Nerven in Zusammenhang stehend.
    Notizen: Summary When the first leg of the crayfish is thrown off at the breaking joint, no muscles are injured, and the muscles for the new leg are formed from cells proliferated by the ectoderm. Although the nerve is torn when autotomy takes place, the cells to form the new nerve (or at least the new nerve sheath), are also differentiated from cells proliferated by the ectoderm. In the hermit crab also the muscles of the new leg are formed by ectodermal cells. If, after the leg of the hermit crab has been thrown off at the breaking joint, the base is split lengthwise so that the nerve is divided or cut in two, there often appear two new legs, one connected with each end of the old nerve.
