    Description / Table of Contents: Summary Adrenal venous blood samples were collected from conscious dogs and analysed for 17-hydroxycorticosteroids (17-OHCS) and catechol amines. Potassium cyanide was administered subcutaneously in doses of 1.0–4.0 mg/kg. The pre-injection secretion rates of 17-OHCS per gland were 0.02–0.26 μg/kg/min. In all the experiments, the 17-OHCS secretion rates increased after cyanide injection to maximal values of 0.60–1.55 μg/kg/min. After injection of 1.0–3.0 mg/kg cyanide, the adrenal medullary secretion rates remained unchanged. Dogs given 4.0 mg/kg cyanide had elevated adrenal medullary secretion rates when anoxic symptoms, such as convulsions, were manifested. The present findings suggest that adrenal cortical response is more sensitive than adrenal medullary response to cyanide anoxia.
    Notes: Zusammenfassung Nebennierenvenenblut wurde an nicht narkotisierten und nicht gefesselten Hunden entnommen und der Gehalt an 17-Hydroxycorticosteroiden (17-OHCS) und Catechinaminen abgeschätzt. KCN wurde in Dosen von 1,0–4,0 mg pro Kilogramm Körpergewicht subcutan eingespritzt. Die Sekretionsgeschwindigkeit von 17-OHCS vor der Injektion betrug 0,02–0,26 μg pro Minute und Kilogramm Körpergewicht. Nach der Injektion war bei allen Dosierungen die Sekretionsgeschwindigkeit stark beschleunigt. Die höchsten Werte betrugen 0,60–1,55 μg pro Minute und Kilogramm. KCN in Dosen von 1,0–3,0 mg pro Kilogramm rief keine Hypersekretion des Nebennierenmarks, dagegen in der Dose von 4,0 mg pro Kilogramm eine ausgiebige Vergrößerung der Sekretionsgeschwindigkeit des Nebennierenmarks hervor. In den vorliegenden Experimenten finden wir demnach einen Hinweis darauf, daß der Sekretionsmechanismus von Nebennierenrinde gegen der Blausäurevergiftung empfindlicher als der von Nebennierenmark ist.

    Notes: Abstract The diffuse far UV radiation (λλ 1350–1480 Å) observed in the sky region ofl II≈180°, 0°≤b II≲40° is analyzed in connection with the distributions of stars and dust grains as well as with optical properties of grains. Its intensity (starlight+scattered light) is about 6×10−7 erg cm−2 sec−1 sr−1 Å−1 in the direction ofb II≈0° andl II≈180°. The latitude dependence of the intensity is in approximate agreement with the plane parallel slab model of the galaxy with a reasonable set of parameters. The interstellar scattering gives an albedo close to unity and forward phase function of about 0.6, which are not inconsistent with the model of interstellar grains of Wickramasinghe. The upper limit of the extragalactic UV is 2×10−8 erg cm−2 sec−1 sr−1 Å−1 in the same region of wave-length.
