    Notes: Abstract A series of 72 measurements of the acetaldehyde (CH3CHO) mixing ratio were made in the lower troposphere during TROPOZ II. These measurements are the first ever made of the background level of this trace gas in the free troposphere. The data show a vertical decrease of the CH3CHO mixing ratio with increasing altitude and indicate higher CH3CHO concentrations in the Northern Hemisphere — in general agreement with a model-derived average CH3CHO distribution. Deviations of the observed CH3CHO mixing ratios from the modelled mean distribution are correlated with similar deviations in the corresponding HCHO mixing ratios.

    Notes: Abstract A series of 149 measurements of the HCHO mixing ratio were made between 0 and 10 km altitude and 70° N to 60° S latitude during TROPOZ II. The data show a vertical decrease of the HCHO mixing ratio with altitude at all latitudes and a broad latitudinal maximum in the HCHO mixing ratio between 30° N and 30° S at all altitudes. The measured mixing ratios of HCHO are considerably higher than those expected from CH4 oxidation alone, but agree broadly with the average latitude by altitude distribution of HCHO derived by a 2D model including emissions of C1–C7 hydrocarbons. A number of the regional scale deviations of the measured HCHO distribution from the average modelled one can be explained in terms of the local wind field.

    Notes: Abstract Nitric oxide (NO) is generated intracellularly from L-arginine by the action of the enzyme nitric oxide synthase (NOS). The present investigation demonstrates immunoreactivity against NOS and nicotinamide adenine dinucleotide phosphate (NADPH)-diaphorase activity in nerve cells and fibers of the reproductive system of the female mouse. The density of nerve fibers staining for NOS varied among different genital organs. The ovary and Fallopian tube were devoid of NOS-positive nerves. The uterine horns received sparse innervation by NOS-containing nerve fibers. The most abundant NOergic innervation was found in the uterine cervix and vagina, where the nerve fibers ran parallel to the smooth muscle bundles and beneath the epithelium; they also accompanied intramural blood vessels. The vaginal muscular wall contained single or groups of NOS-reactive nerve cells. Clusters of NOS-containing neurons were located in Frankenhäuser's ganglion at the cervico-vaginal junction. NO may therefore act as a transmitter in the nervous control of the female reproductive tract.

    Notes: Abstract. Neuronal nitric oxide synthase was located in various organs of the goldfish by NADPH-diaphorase histochemistry and immunohistochemistry. Positive cells were detected throughout the digestive tract. A particularly dense plexus of nitric-oxide-synthase-containing fibers was present at the opening of the pneumatic duct into the esophagus and at the intestinal sphincter separating the esophagus and the intestinal bulb. The nitroxergic innervation was mainly confined to the muscularis. The muscular layer of the swim bladder and of the pneumatic duct was densely equipped with stained neurons and fibers. In the heart, the majority of small neurons located at the sinu-atrial junction was found to be positive for nitric oxide synthase. The muscularis of the urinary duct was supplied by fibers originating from many intramural ganglia harboring intensely stained neurons. These results suggest that nitric oxide represents a widespread transmitter in the peripheral nervous system of teleost species.

    Notes: 1. Untersucht wurde die Sorption von Wasserstoff durch Platinmohre aus verschiedener Herstellung. Für die Analyse der kleinen aus dem Mohr abgepumpten Gasmengen wurde ein von RYDER angegebener Apparat zweckentsprechend abgeändert (Genauigkeit ± 2% der Gesamtmenge bei 0,5 cm3 Gas). Die bei 200° im Vakuum entgasten Mohre sorbierten (bei 0°) 26-44 Vol. H2 auf 1 Vol. Platin. Im übrigen verhielten sich die Proben fast gleich.

    Notes: 1. Für die Reduktion von 1 Mol H2PtCl6, sind, falls hinreichend Alkali zugegen ist, in der Kälte 2 Mol Formaldehyd erforderlich (Oxydation zu Formiat), in heißen Lösungen genügt 1 Mol Formaldehyd (Oxydation zu Carbonat). Steigende Mengen von Formaldehyd und Alkali beschleunigen den Reduktionsvorgang. Für stöchiometrische Messungen eignet sich der Formaldehyd nicht, weil Nebenreaktionen stören (CANNIZZARO'sche Reaktion).

    Notes: Freie 4-Amino-4.5-didesoxy-L-xylose und 4-Amino-4-desoxy-L-xylose wurden durch alkalische Spaltung aus ihren Derivaten 7 und 6 dargestellt und in ihren Reaktionen untersucht. Beide Verbindungen weisen in Lösung ein Gleichgewicht zwischen Pyrrolidin-Formen 11, 12, Δ1-Pyrrolin-Formen 13, 14 und den Dimeren 9, 10 auf, in dem die Dimeren 9, 10 weit überwiegen. Die Struktur der erhaltenen Dimeren 9, 10 folgt aus den NMR-Spektren von 9 und seiner Derivate und aus der Spaltung des N-Acetats 20 in 12 und 15. Die Dimeren werden durch Hydrierung, mit Schwefeldioxid und mit Blausäure glatt in monomere Derivate zerlegt. Sie sind gegenüber Salzsäurebehandlung überraschend stabil und bilden keine Pyrrolderivate.
