    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Unter 28 Neugebornen mit Ikterus prolongatus und niedrigen Alpha-1-Antitrypsin-Konzentrationen im Serum wurde sechsmal ein Pi-Typ MZ, dreimal MS und einmal MP gefunden. Ein Neugeborenes besaß den Pi-Typ SZ (doppelte Heterozygotie), ein Kind war homozygoter Merkmalsträger des Pi-Typs S. Die nachgewiesene hohe Frequenz von über 40% homozygoter oder heterozygoter Träger (möglicherweise die Leberfunktion beeinflussender Allele) des Pi-Systems läßt den Schluß zu, daß von der Norm abweichende Alpha-1-Antitrypsin-Genotypen für bisher nicht erklärbare Fälle von Ikterus prolongatus in der Neugeborenenperiode ursächlich in Frage kommen.
    Notizen: Summary Of 28 newborns with prolonged jaundice and lowered or subnormal values of alpha-1-antitrypsin in the serum six patients were found to have a Pi-type MZ, three a Pi-type MS and one patient a Pi-type MP. One of the newborns had Pi-type SZ (double heterozygous), one infant was a homozygous carrier of the Pi-type S. It seems to the possible that one of the reasons for the not yet explained cases of prolonged jaundice of the newborns period can be found in the high frequency of homozygous or heterozygous genotype carriers of Pi-system.

    Notizen: Abstract The present paper concerns the stagnation flow produced by counter flowing air jets. Little experimental information exists on such flows in spite of their extensive employment in the theoretical treatment of diffusion flames. To remedy this situation, laser-Doppler measurements were performed to quantify the entire flow field. The experiments are described and the results of the velocity measurements presented. Differences between the investigated flow field and the ideal flow field, employed in theoretical studies, are pointed out.

    Notizen: Abstract In axisymmetric flows, we show that the laser beam deviation technique can be associated with an Abel inversion calculation in order to give the local density and its gradients. We report density profile measurements in the different regions (zone of silence and barrel shock) of nitrogen and argon supersonic free jets near the nozzle exit. Three different nozzle geometries have been tested at different stagnation pressures. Results are compared to calculations obtained by the method of characteristics.

    Notizen: Abstract Two polymorphisms were detected within exon 14 of the inter-alpha-trypsin inhibitor heavy chain H1 (ITIH1) gene. The polymorphisms are detected by digesting the same 202-bp polymerase reaction product with the PstI and HphI restriction endonucleases. These gene polymorphisms lead to the change of two amino acids in the mature protein. The polymorphisms can be used for the analysis of 3p21 deletion in human carcinomas as well as to develop a better understanding of the protein polymorphism already described.

    Notizen: Summary Humic acids from two Brazilian topsoils under savanna grassland and five soil fungal melanins were characterized by elemental, functional group and infrared analysis. C, N, total acidity, COOH, and phenolic OH contents were within the ranges reported for several other fungal melanins and soil humic acids. Compared with the soil humic acids, the infrared spectra of the fungal melanins showed greater detail, indicative of higher aliphaticity. They were similar to the type III infrared spectra of humic acids, which are characteristically high in proteinaceous material and polysaccharides. The infrared spectra of the humic acids from the two Brazilian soils studied were classified as type I, which includes most soil humic acids. Notwithstanding the greater detail, in some areas the fungal melanin spectra were similar to those reported for other fungal melanins and humic acids of different origins. The probable contribution of the melanic fungi to the formation of soil humic polymers is discussed.

    Notizen: Summary Humic acid-type polymers (melanins) synthesized in culture media by the fungi Aspergillus glaucus, Eurotium echinulatum, Hendersonula toruloidea, Stachybotrys atra and Aspergillus sydowi were analysed for elemental composition, functional group content, infrared (IR) and electron spin resonance (ESR) properties. Results were discussed in comparison with range values referred for soil humic acids. The fungal polymers showed significant differences in carboxyl and nitrogen content and C/H atomic ratios, reflecting a different degree of condensation (aromaticity) among the various samples. IR analysis gave evidence of: (a) the predominant aromatic character of melanins from A. glaucus, E. echinulatum and H. toruloidea; (b) the high content of aliphatic and olefinic components of S. atra melanin; (c) the typical presence of amide bonds in the nitrogen-richest melanins from A. sydowi and H. toruloidea; and (d) the generally low amount of free carboxyl groups, which often appeared involved in hydrogen bonds. ESR spectra showed that all the melanins studied contained appreciable concentrations of organic free radicals of prevailing semiquinonic nature and of the same order of magnitude commonly measured in humic acids from soil and other sources. The free electron concentration was shown to be directly related to the C/H atomic ratio and to the degree of aromaticity shown by IR analysis. This indicated that the highest free radical content in the melanins from E. echinulatum and A. glaucus was associated with the highest presence of condensed aromatic structures. Humic acid-type polymers synthesized by soil fungi may, therefore, contribute to the total free radical content of soil humic substances and play important roles in all reactions involving free radicals in soils and related environments.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Die Zugabe von Montmorillonit zu Kulturlösungen verschiedener Mikroorganismen ergab bei Schüttel- oder Standkulturen meist eine Steigerung der Biomasse und einen erhöhten Nährstoffverbaruch. Diese Steigerung wurde besonders unter aeroben Verhältnissen und in den ersten Wachstumsphasen beobachtet. Die Bildung von Äthanol durch S. cerevisiae bzw. Citronensäure durch A. niger war beschleunigt, aber nicht wesentlich erhöht. Manometrische Messungen mit S. cerevisiae ergaben in Abhängigkeit von der Montmorillonit-Konzentration einen höheren RQ. Die Relation der Biomasse zu verbrauchter Glucose deutet auf eine bessere Ausnutzung der Energiequelle für synthetische Prozesse hin.
    Notizen: Summary The addition of montmorillonite to stationary and shake-cultures of various microorganisms usually increased total biomass formation and accelerated the utilization of nutrients. These effects were noted especially under aerobic conditions and during the initial growth phases. The formation of ethanol by S. cerevisiae and citric acid by A. niger was accelerated, but not significantly increased. manometric measurements with S. cerevisiae showed a higher RQ which increased with increasing montmorillonite concentrations. The relation between biomass formation and glucose consumption indicates a more efficient utilization of the energy source for synthetic processes.
