    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.

    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: 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.

    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.

    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.

    Notes: Abstract The boron contents of 68 edible common macrofungi of Hungary were analysed. The average boron content of the examples was 11,74 mg/kg dry mass, this is higher than the average value of green plants of Hungary (7,4 mg/kg dry mass). Although the highest boron contents were found in the examples from woods near Budapest, the differences between the various sites are not significant. It seems that the site has not an important effect on the boron content of mushrooms. Some taxonomical groups are examples of higher, others are examples of lower boron content. The highest concentration of boron (54,3 mg/kg dry mass) was found in the speciesMarasmius wynnei which indicates a bioconcentration of four to five fold to the average boron level. Significant bioaccumulation of analysed edible species was not established, but the poisoning mushroomMycena pura has a very great (401–607 mg/kg dry mass) boron concentration. This accumulation is observed to the first time.

    Expression of osteoblastic markers in cultured human bone and fracture callus cells (1995)

    Notes: Abstract We compared the expression of osteoblastic markers in cultured human cells isolated from fracture calluses of various histological states of development with that in cells from adult and fetal bone. Adult osteoblasts and all callus cells produced almost exclusively type I collagen, whereas fetal osteoblasts produced also considerable amounts of type III collagen in vitro. 1,25-Dihydroxyvitamin D3 induced the synthesis of osteocalcin in all bone and callus cells but to varying extents. Fetal bone cells and early-stage callus cells synthesized less than 10% the amount of osteocalcin produced by adult bone cells. Late-stage callus cells produced intermediate levels of osteocalcin. Fetal bone cells and early-stage callus cells responded to parathyroid hormone with a less pronounced increase in intracellular cAMP than did adult bone cells. Late-stage callus cells showed the best response to parathyroid hormone. The activity of alkaline phosphatase was highest in fetal bone cells. These observations show that cells isolated from fetal bone and from fracture callus tissues express a pattern of markers clearly relating them to the osteoblastic lineage. On the basis of the different patterns of osteoblastic markers expressed in vitro we conclude that functionally distinct subtypes of osteoblasts do exist in different mineralized tissues and at different developmental stages.

    Notes: Abstract  Angiotensin II is involved in blood pressure regulation, cell growth and angioneogenesis. The angiotensin receptors which mediate the intracellular effects of angiotensin II are expressed in numerous tissues and cell types. We studied the expression of angiotensin II receptors in cultured human skin fibroblasts derived from a skin biopsy. Angiotensin II binding characteristics were analyzed by radioligand binding assays. The DNA synthesis was assessed by [H]thymidine incorporation assays. Intracellular calcium concentrations were measured by fura-2 spectrofluorometry, and mRNA expression levels were analyzed by northern blot technology. Two distinct angiotensin receptors were detectable on human skin fibroblasts: the AT1 receptor with K d=1.0± 0.7 nmol/l and B max=17.9±0.9 fmol/mg protein, and an angiotensin(1–7) binding site with K d=26±6.6 nmol/l and B max=80.4±3.5 fmol/mg protein, as shown by competition binding assays using selective angiotensin II receptor antagonists and the heptapeptide angiotensin(1–7). The angiotensin AT1 receptor mRNA was substantially expressed in human skin fibroblasts and was subjected to homologous downregulation. In human skin fibroblasts angiotensin II caused a profound increase in intracellular calcium which was blocked by angiotensin AT1 receptor antagonists such as Exp-3174. Furthermore, both angiotensin II and angiotensin(1–7) led to increased DNA synthesis in human skin fibroblasts. In conclusion, cultured human skin fibroblasts express angiotensin AT1 receptors and a putatively new angiotensin receptor activated by angiotensin(1–7), both coupled to signaling pathways involved in DNA synthesis.
