    Description / Table of Contents: Summary An A3 blood sample did not react to extracts containing anti-Ahel. These extracts were produced from the protein gland of Helix pomatia. Other samples of the special type A 3 w showed a stronger reaction, however. The different reactions are to be taken from the table.
    Notes: Zusammenfassung A3-Blutkörperchen reagieren mit Extrakten von Drüsen aus Helix pomatia entweder nicht oder nur sehr schwach, A2-Zellen reagieren oft stärker mit Anti-Ahel als A1-Zellen. Bei allen Versuchen zeigten sich geringe Unterschiede gegenüber dem Anti-Ahel aus Helix hortensis. Abschließend werden grundsätzliche Betrachtungen zur Immunchemie der A-Untergruppen angestellt.

    Description / Table of Contents: Zusammenfassung Verschiedene chemische Bestandteile des Samens und der Samenschale der Ackerbohne (Vicia faba L.) wurden untersucht. Die Samen enthalten einen relativ hohen Roheiweiß- (27,5%), niedrigen Rohfett(3,36%) und Ligningehalt (2,65%). Die Samenschale hat eine hohe Faserkonzentration und ist eine bedeutende Ca-Quelle (1,86 g/kg TM). Die höchsten Makroelementkonzentrationen wurden aus Kalium, Phosphor und Magnesium registriert. Die Hauptmikroelemente (Fe, Mn, Cu, Zn) kommen in bedeutend höheren Konzentrationen in den Samen als in der Samenschale vor. Die Aminosäurezusammensetzung der Samen ist positiv (verglichen zu weißer Lupine), das Verhältnis der essentiellen Aminosäuren ist gut. Die Konzentrationen der untersuchten antinutritiven Stoffe, besonders der Alkaloide, sind niedrig. Auf Grund der angeführten chemischen Untersuchungen ist diese Pflanze eine der wertvollsten Hülsenfrüchte; der Anbau und die Verwendung der Samen scheint zukunftsreich zu sein.
    Notes: Abstract Different chemical components were analysed in the seeds and in testa ofVicia faba. The seeds contain a relativ high crude protein (27,5%), a low crude fatt (3,36%) content; and the lignin concentration is low (2,65%). The testa of the seeds has a very high fibre concentration and is a significant Ca-source (1,86 g/kg). The higher macroelement concentrations in the seeds were measured from K, P and Mg. The main microelements (Fe, Mn, Cu, Zn) have significant higher concentrations in the seed than in the testa. The amino acid composition of seeds is positiv (compared to data of white lupine), the rate of essentiell amino acids is good. The concentrations of the examined antinutritiv organic constituents, especially of alkaloids, are low. On the basis of chemical analysis, the production and utilisation of seeds ofVicia faba is recommended.

    Alarm pheromone perception in honey bees is decreased by smoke (Hymenoptera: Apidae) (1995)
    Springer
    Journal of insect behavior 8 (1995), S. 11-18

    Notes: Abstract The application of smoke to honey bee(Apis mellifera) antennae reduced the subsequent electroantennograph response of the antennae to honey bee alarm pheromones, isopentyl acetate, and 2-heptanone. This effect was reversible, and the responsiveness of antennae gradually returned to that of controls within 10–20 min. A similar effect occurred with a floral odor, phenylacetaldehyde, suggesting that smoke interferes with olfaction generally, rather than specifically with honey bee alarm pheromones. A reduction in peripheral sensitivity appears to be one component of the mechanism by which smoke reduces nest defense behavior of honey bees.

    Notes: Abstract The half lives of the 5/2 5/2−[523] level at 25.7 keV in 66 161 Dy and the 5/2 5/2+[642] level in 68 163 Er, found in this work to lie at 69.2 keV, have been determined by the delayed coincidence method to be T1/2=27.8± 1.5 nsec, and T1/2=8.8± 0.5 nsec, respectively. The following hindrance factors relative to the single particle Weisskopf estimate (F W and the Nilsson estimate (FN were obtained: 66 161 Dy 5/2 5/2−[523] → 5/2 5/2+[642]:FW=(6.6± 1.3) × 103, FN=0.48± 0.10 68 163 Er 5/2 5/2+[642] → 5/2 5/2−[523]:FW=(2.4± 0.5)× 104, FN=1.8 ± 0.4 A systematic difference between transitions in odd proton nuclei and odd neutron nuclei was found: E1, ΔK=0 transitions in odd neutron nuclei have hindrance factors FN from 2.9 to 0.16, this means, these transitions are in agreement with the predictions of the Nilsson model within a factor of 10. For transitions in odd proton nuclei one has hindrance factors FN from 75 to 9.9 × 10−4. It is shown that a small difference between the deformation of the initial and the final state changes the transition probability of both, proton and neutron transitions, considerably.

    Notes: Abstract: High–spin states in 200Hg have been investigated by in–beam γ–ray spectroscopy following the reaction 198Pt(9Be,α3n). The α–emission channel leading to 200Hg is strongly enhanced which may be explained by an incomplete fusion reaction with pre–equilibrium emission of the α particle. The level scheme is extended to higher spins and new band crossings are observed. The band structures are compared to the lighter Hg isotopes with even mass number.

    Lifetime of the two-phonon vibrational state in232Th (1995)

    Notes: Abstract We report on a measurement of the lifetime of the 1414 keV state in232Th by the Doppler-shift recoil-distance method. This 4+ state shows all characteristics of a nearly-harmonic two-phononγ-vibrational excitation. The result for the B(E2) value obtained from the lifetime,τ=3.2 ± 0.7 ps, is in agreement with an earlier estimate of the collectivity from Coulomb-excitation yields and supports the interpretation of the 1414 keV state as a two-phononγ-vibrational excitation.

    Notes: Zusammenfassung Bei thermischer oder solvolytischer Decarbonylierung eines neuen Alkaloids ausMelodinus scandens Forst. entsteht eine Verbindung II, die ihrerseits in die Derivate III–VI umgewandelt werden kann. Auf Grund eingehender NMR- und MS-Untersuchungen können für die Verbindungen II–VII die angegebenen Strukturen vorgeschlagen werden. Alkaloide mit dem Skelett der Verbindung II entstehen biosynthetisch wahrscheinlich aus Alkaloiden des Aspidospermin-Typs durch Oxidation an C-2 und nachfolgende Umlagerung.

    Description / Table of Contents: Zusammenfassung Weltweit werden jährlich etwa 200000 t des Shii-take Pilzes (Lentinus edodes) produziert. Verschiedene positive, biologische Wirkungen sind bekannt (anticarcinogene, cholesterinsenkende Wirkungen und stimulierende Wirkungen auf das Immunsystem), aber die Mineralstoff- und Aminosäuregehalte des Pilzes sind bislang nur wenig untersucht. Die Mineralstoffgehalte sind im allgemeinen niedriger als die des Kulturchampignons (Agaricus bisporus) oder des Austernseitlings (Pleurotus ostreatus). Die größten Unterschiede liegen bei den Kalium-, Phosphor-,Calcium-, Kupfer-, Strontium-, Mangan- und Zinkgehalten vor. Die Gehalte sind in Hüten höher als in den Stielen. Der Gesamtaminosäuregehalt beträgt 15,24% in den Hüten und 11,35% in den Stielen, bez. auf Trokkenmasse, und beträgt somit etwa die Hälfte des Gehaltes von Kulturchampignons. Die Phe-, Gly, His-, Arg-, Ile- und Met-Gehalte sind relativ höher als die von Champignon-Sorten.
    Notes: Abstract World wide about 200000 tons of shii-take mushrooms (Lentinus edodes) are produced per year. Different positive biological effects are known (anticarcinogenic, anticholesterol, immunostimulating effects), but the mineral contents and amino acid composition of caps and stipes are still little investigated. The concentrations of minerals are in general lower than those in the cultivated white mushroom (Agaricus bisporus) and in the oyster mushroom (Pleurotus ostreatus). The greatest differences are found in the concentrations of potassium, phosphorus, calcium, copper, strontium, manganese and zinc. The cocentrations are higher in caps than in stipes. The total amino acid content is 15,24% in caps and 11,35% in stipes (dry matter) and thus in general half of the concentration of cultivated champignon. The amounts of Phe, Gly, His, Arg, Ile and Met are relative higher than inAgaricus fruit bodies.
