    Notes: [Auszug] Since a major step in the formation of gall-stones appears to be the bacterial 7-dehydroxylation of allocholic acid, it is reasonable to assume that the reduction or elimination of the bacteria responsible for the conversion might interfere with gall-stone formation. Because of its well-known ...

    Notes: Abstract The nucleus considered as a Fermi-gas is supposed to consist of several subsets of fermions with a constant number of nucleons in each subset. With this assumption the exponentn in the level density formulaρ(U)∼ U −n exp(2 √aU) is found to increase by 0.25 per additional subset.

    Notes: Abstract Protons from nuclear reactions induced by 14 MeV neutrons are analysed with solid state detectors. A high background is caused by nuclear reactions in silicon. The application of a telescope with twodE/dx- detectors allows to suppress this background extensively. Proton identification is made by use of a two-dimensional analyser. The telescope is tested by recoil protons with polyethylene. This arrangement may also be used as a neutron spectrometer. The proton spectra from the reaction Ni(n, p)Co in forward direction (0°) and on an angle of 90° are compared. Nuclear temperature and level-density parameter are evaluated from statistical theory plots. The contribution of direct processes is estimated.

    Notes: Abstract The polarization of neutrons from thed-d-reaction was investigated in the energy regionE d=80 to 140keV at an angle ofΘ 1=50°lab. Using a polarimeter consisting of a He-gasscintillation detector and two plastic detectors it was possible to reduce the background to a negligible amount. A maximum of neutron polarization of (−14.9 ±2.2)% was found atE d=100 keV. The resonancelike behavior is a further indication of an unknown excited level in4He at 23.9 MeV as given in ref.14.

    Notes: Zusammenfassung Es wird die Isolierung eines neuen Isomeren des Ergokryptins beschrieben, das sich von diesem nur durch den Ersatz des Leucin-Restes durch den Isoleucin-Rest im Peptidteil des Moleküls unterscheidet. Das neue Isomere soll alsβ-Ergokryptin und das früher beschriebene Alkaloid alsα-Ergokryptin bezeichnet werden. Die beiden Isomeren, ebenso ihre Dihydro-Derivate, unterscheiden sich pharmakologisch nur ganz unwesentlich.

    Notes: Summary Our first aim was to simplify the spacer-synthesis for affinity-chromatography of cholinergic proteins. Further-more we synthesized 2 new inhibitors which proved to be useful for purification of acetylcholine-receptor protein.

    Notes: Abstract Levels of free-abscisic acid and “boundabscisic acid” (alkaline hydrolyzable abscisic acidesters) in replicated samples of terminal vegetative buds of sycamore trees were measured during natural emergence from winter dormancy by gas chromatographic methods together with isotope dilution estimation of recovery rates. Not until after the buds had been released from true dormancy in January by winter chilling did any clear change occur in either abscisic acid (ABA) fraction, or in total ABA, on any basis of comparison. The percentage of total ABA present as the free acid declined at the end of true dormancy to approximately two-thirds of its value in the earlier winter months. It is concluded that glucosylation of ABA is unlikely to play a major part in the mechanism of release from dormancy in vegetative sycamore buds. At the end of true dormancy there was a large transient increase in what appeared to be phaseic acid, but this was not accompanied by any marked decrease in either free- or bound-ABA.

    Description / Table of Contents: Zusammenfassung Um im Schimpansen die hepatische Biotransformation der primären Gallensäure Chenodeoxycholsäure und deren wichtigstem bakteriellen Metaboliten, Lithocholsäure zu charakterisieren, wurde ein Gemisch aus Spurenmengen von14C-Lithocholsäure und3H-Chenodeoxycholsäure intravenös in zwei Tiere mit Gallenfistel injiziert. Die chemische Form der Radioaktivität, die in der Galle erschien, wurde dünnschichtchromatographisch ermittelt. Etwa 80% der Chenodeoxycholsäure und 70% der Lithocholsäure wurden innerhalb von 90 min ausgeschieden. Die Chenodeoxycholsäure war vollständig konjugiert und erschien vorwiegend als Chenyltaurin (52%) und Chenylglycin (37%). 11% erschienen in einer Form, die bisher nicht identifiziert wurde. Lithocholsäure wurde vollständig als Taurin- und Glycinkonjugat in die Galle eliminiert; der größte Teil (63%) war zusätzlich sulfatiert. Die Sulfatierung nahm stetig mit der Zeit zu und Lithocholylglycine wurde stärker sulfatiert als Lithocholyltaurin. Wir schließen aus diesen Befunden, daß der Schimpanse mit dem Menschen vergleichbar ist, indem er Lithocholsäure effektiv sulfatiert. Dadurch unterscheidet sich der Schimpanse vom Rhesusaffe und Baboon, die die Lithocholsäure nur in geringem Maße sulfatieren. Jedoch unterscheidet sich der Schimpanse auch vom Menschen und ähnelt dem Rhesusaffen und dem Baboon, indem er Gallensäure vorwiegend mit Taurin konjugiert. Die Ergebnisse lassen den Schluß zu, daß die Hepatotoxizität, die im Rhesusaffe und Baboon durch Chenodeoxycholat hervorgerufen wird, und auf eine geringe Sulfatierung der Lithocholsäure zurückgeführt wird, beim Schimpansen nicht bestehen sollte.
    Notes: Abstract To characterize the hepatic biotransformation in the chimpanzee of the primary bile acid chenodeoxycholic acid (chenic) and its major bacterial metabolite lithocholic acid (lithocholic) a mixture of tracer amounts of14C-lithocholic and3H-chenic was injected intravenously into two animals with a bile fistula; the chemical form of radioactivity appearing in bile was inferred using thin layer chromatography. About 80% of chenic, and 70% of lithocholic was recovered in 90 min. Chenic was completely conjugated in bile, appearing predominantly as chenyltaurine (52%) and chenylglycine (37%). An unidentified conjugate (about 11%) was also found. Lithocholic was excreted completely as taurine and glycine conjugates, but the majority (63%) of conjugates was sulfated. Sulfation increased progressively with time, and lithocholylglycine was sulfated more than lithocholyltaurine. We conclude that the chimpanzee is similar to man in that the secondary bile acid lithocholic is efficiently sulfated. The chimpanzee thus differs from the baboon and rhesus monkey which sulfate lithocholic poorly. However, the chimpanzee differs from man and is similar to the baboon and rhesus monkey in showing preferential conjugation of bile acids with taurine. The results imply that hepatotoxicity caused by chenic, which is well documented in the rhesus monkey and baboon and has been related to defective lithocholic sulfation, should not occur in the chimpanzee.
