Die intracelluläre Quarzspeicherung in den tracheobronchialen Lymphknoten
Authors: Nemetschek Th. , Widuch M. , Schlipköter H.-W. 
Published: February 2015

Les gangliones lymphatiques pulmonales des rats avec une silicose experimentale montrent - ainsi que le tissu du poumon - des zones détruites, largement entremêlées avec des fibrils de collagène.
Des coupes ultrafines en série permettaient de reconnaître la poussière de quartz dans la cellule.
Le quartz est limité très nettement et logé librement dans la matrice cytoplasmique fondamentale sans aucune membrane ou autre matière limitant. Aussi les repliques des ces particules intracellulaires n’avaient pas des substances insolubles en acide fluorhydrique et réflétèrent des surfaces de cristal perturbé inégal comme chez autres cristaux réels.
La plupart des conglomérats avait des longs, plats cristaux, malgré que l’emprunt de quartz ne présenta des particules similaires qu’en mélange avec des cristaux granulaires, ce qu’indique la possibilité d’une stockage séléctive des cristaux.

Das Druck/Zusammensetzungs-Diagramm des Systems Ammoniumbutyrat/Ammoniak wurde zwischen — 78 und — 33 °C im Bereich von ca. 0 bis 760 Torr NH3-Dampfdruck aufgenommen. Für die Dampfdrucke der beobachteten Phasen sind die Gleichungen berechnet worden:
(1) log p = 9,259-1701,5/T für die Verbindung n-C3H7COONH4 · NH3 [gültig von ca. —78 bis —6°C], (2) log p = 8.198 — 1276.3/T für gesättigte Lösungen der Zusammensetzung n-C3H7COONH4 · (ca. 99,0-6,7)NH3 [von —77.9 bis —43,3 °C] und (3) log p = 6.815-959,1/T für gesättigte Lösungen n-C3H7COONH4 · (ca. 6,7-3,1)NH3 [von —43,3 bis —28,0 °C].
Bei —33,4 °C und 652.0 Torr NH3-Druck betrug die Dichte des Ammoniumbutyratammins DXX = 1,043 g/cm3, die der Lösung n-C3H7COONH4 · 3,58 NH3 DL = 0,899 g/cm3.
Vergleichende Untersuchungen löslicher Proteine aus Embryonalleber, Normalleber erwachsener Tiere und Transplantations-Tumoren der Ratte mit Hilfe der Agar- und Papierelektrophorese
Authors: Fritz W. 
Published: February 2015

Embryonalleber unterscheidet sich elektrophoretisch sowohl in der qualitativen als auch quantitativen Verteilung der Fraktionen von der Normalleber erwachsener Ratten.
Als schneller wachsendes Gewebe ähnelt ihr Elektropherogramm den Transplantations-Tumoren der Ratte, besonders aber dem Hepatom.
Da Tumoren charakteristische Elektropherogramme zeigen, wird vorgeschlagen, Tumoren neben dem histologischen Bild auch elektrophoretisch zu charakterisieren. An Metastasen-freien Lebern Tumor-tragender Ratten fanden wir im Gegensatz zu anderen Autoren lediglich quantitative Veränderungen.
Strahlenchemische Erzeugung und optische Absorptionsspektren organischer Schwefelradikale in organischen Gläsern bei —196 °C
Authors: Wendenburg J. , Möckel H. , Granzow A. , Henglein A. 
Published: February 2015

Organic disulfides, mercaptans, sulfides and hydrogen sulfide have been exposed to γ-radiation in glasses of methyltetrahydrofuran or hydrocarbons at -196 °C. Absorptions have been observed which are attributed to either radicals of the type RS· or to addition complexes of these radicals to S-containing molecules or ions (for example to RS-SR- radical ions). In the case of disulfides. the S-radicals were produced by dissociative capture of electrons from the ionization of the glassy solvent. In the case of mercaptans, the sulphur radicals were formed via H-abstraction by free radicals from the radiolysis of the solvent, when the irradiated glasses were slowly warmed up. HS was formed this way in H2S containing irradiated glasses. The electron capture in benzylmercaptan, dibenzyldisulfide, and dibenzylsulfide partially leads to the benzylradical. Several new absorption bands have been observed which are tentatively attributed to negative ions: C6H5SH⊖ from phenylmercaptan (8100 A), C6H5SC6H5
e from diphenylsulfide (broad absorption over the visible range), C6H5CHS⊖ from dibenzylsulfide (~ 3900 A). Carbontetrachloride simultaneously present in the glass was found to inhibit all reactions of free electrons, while the reactions of free radicals during warming up were not suppressed.
Glasses of a methylcyclohexane-isopentane mixture containing olefins were found to absorb strongly between 7000 and 9000 A. These absorptions are attributed to positive ions. The absorption of ionized or protonated olefins occurs at longer wave lengths with decreasing number of Η-atoms at the carbon atoms of the double bond. Absorption by positive ions was also observed for diphenyldisulfide (8500 A), and for diallyldisulfide (6840 A). Small amounts of substances which can readily be protonated (such as n-propanol or methyltetrahydrofuran) decrease the intensity of the absorption bands of positive ions.
II. Mitt.: Zur Immunmorphologie der „Plaque-bildenden“ Milchflecken im Mäuseomentum
Authors: Kaboth U. , Ax W. , Fischer H. 
Published: February 2015

Mice were immunized by intraperitoneal injection of sheep erythrocytes. The morphology of the cells which consecutively accumulate in non-vascularized milky spots has been studied on stained omental spreads. Macrophages, lymphocytes, large pyroninophilic cells, plasma cells, mast cells and eosinophilic granulocytes were found to be present in varying numbers depending on the stage of the immune process. Mast cells and eosinophilic granulocytes appeared in appreciable numbers not before several weeks after immunization.
Milky spots - caused by intraperitoneal stimulation with two morphologically different types of erythrocytes (pigeon-sheep; camel-sheep) were shown to produce antibodies against both cell types. This was demonstrated with a modification of the Jerne - plaque-technique. By contrast, single cells, isolated from doubly-producing milky spots released antibody directed against either sheep or pigeon resp. camel erythrocytes. Thus far no doubly producing single cells have been found.
Enzyme der Vakuolen aus Wurzelzellen von Maiskeimlingen. Ein Beitrag zur funktionellen Bedeutung der Vakuole bei der intrazellulären Verdauung
Authors: Matile Ph. 
Published: February 2015

The isolation of vacuoles from rootlets of corn seedlings based on the slicing and chopping of the plasmolized tissue is described. The isolated vacuoles have densities higher than 1,029 g cm-3; in the centrifugal field they rapidly move centripetally if the extracts are brought to a density of 1,185 g cm-3 by the addition of 30% of “Urografine”. Thus a simple separation of isolated vacuoles from the extracts could be achieved.
The following hydrolytic enzymes have been localized in isolated vacuoles: protease, RNase, DNase, phosphatase and two different unspecific esterases. Furthermore two transaminases, aspartate and alanine-aminotransferase and two oxyreductases cytochrome-c-reductase and diaphorase are present in preparations of isolated vacuoles. The absence of mitochondrial enzymes and of enzymes known to be localized in the groundplasm indicated the purity of the preparations of vacuoles.
It is concluded that the vacuoles of higher plant cells represent organelles in which the processes of intracellular digestion take place.
Ein Modell der Plaquebildung
Authors: Schwöbel W. , Geidel H. , Lorenz R. J. 
Published: February 2015

A model has been developed to simulate the spread of virus infection in cell cultures. The structure of the model assumes that a) cells of two dimensional monolayers are regular hexagons, b) the number of infective units produced by a single cell is a Poisson distributed variable, c) a virus releasing cell can only infect neighbouring cells, and d) all neighbouring cells have an equal chance to become infected.
The growth of model plaques was studied with the aid of a computer using different mean values (λ) of the Poisson distribution. The radius of model plaques increases linearly with time. The speed of this process depends upon the value of λ. The shape of the plaques varies and this variability is also a function of λ. The highest frequency of irregularly formed plaques is found when λ is 2.2. At low values of λ, plaque growth may end by itself.
Model plaque formation has been compared with actual plaque formation by foot and mouth disease virus and good agreement was observed. The use of the model bor the study of other epidemiological phenomena is discussed.
Über den K-Transport bei der K-Mangelmutante E. coli B 525
Authors: Günther Th. , Dorn F. 
Published: February 2015

Der intracelluläre Na- und K-Gehalt von E. coli B 163 und seiner K-Mangelmutante B 525 wurde in Abhängigkeit von der extracellulären K-, Na- und H⊕-Konzentration sowie in Gegenwart verschiedener Substrate und Stoffwechselinhibitoren untersucht.
E. coli B 163 und seine K-Mangelmutante B 525 transportieren K aktiv in die Zelle. Durch die Mutation ist der Austritt des K aus der Zelle erhöht. Die Versuchsergebnisse lassen auf eine Carrier-begünstigste Diffusion des K aus der Zelle schließen. Dieser Carrier müßte durch die Mutation eine höhere Affinität für K bekommen haben und nun gleichzeitig mit Na reagieren
Verfolgung der in vivo-Oxydation von 17-Hydroxy- zu 17-Ketosteroiden durch Messen der Tritium-Aktivität im Körperwasser
Authors: Wenzel M. , Kleucker H. , Schulze P. E. 
Published: February 2015

Östradiol-17 α-T wird durch die 17-Hydroxy-Steroid-Dehydrogenase, mit DPN oder TPN als Coenzym, zu Östron oxydiert. Dabei entstehen DPN-T bzw. TPN-T, die das Tritium in die Atmungskette einschleusen. Das gebildete Tritiumwasser erscheint im Harn und in der Atemluft und wird bei Kleintieren (Ratte, Maus) unmittelbar gemessen. Der Gehalt an Tritium in der Atemluft bzw. im Harn ist somit ein Maß für die Reaktionsgeschwindigkeit Östradiol-17 α-T → Östron.
Es wurde gefunden, daß Rattenweibchen, ohne und nach Progesterongabe, Tritium gleich schnell aus dem Östradiol-17 α-T umsetzen und nach 7—9 Stdn. etwa 80% ins Körperwasser überführen.
Östradiol-6.7-T gibt dagegen kein Tritium ins Körperwasser ab.

Published: February 2015

Abstract
Polyborates, Ammonium Borates, Isopolyanions, Tris(methoxy)borane, Hydrolysis The preparation of polyborates with bulky cations in organic solvents by the method of "ester hydrolysis" as well as by the method of evaporation of solutions of the base and boric acid reactands under reduced pressure with the very strong bases benzyltrimethyl-ammonium hydroxide and benzyltriethylammonium hydroxide leads to [C6H5CH2N(CH3)3][B5O6(OH)4] and [C6H5CH2N(C2H5)3][B5O6(OH)4]. The more bulky, but less basic tri-n-butylamine yields a heptaborate, presumably [(C4H9)3NH][B7O6(OH)10]. The less bulky, but more basic triethylamine or tri-n-propylamine yield [(C2H5)3NH][B5O6(OH)4] or [(C3H7)3NH][B5O6(OH)4]. The most bulky, but less basic benzylamine or tri-n-octylamine are not capable to function as cations in polyborates.

Cyclic Amidines Complexes: Complexes of 5:6:11:12-Tetrahydro-2,8-dimethylphenhomazine with Copper(II), Nickel(II) and Zinc(H)
Authors: Hussain M.Sakhawat , Rehman Saeed-Ur 
Published: February 2015

Abstract
The title compound, PHZ, can be viewed as 1,5-diazacyclooctane (daco) having carbon-3 and carbon-7 fused to benzene rings restricting the vibrational freedom of these carbons and rendering the axial positions in the complexes open for fifth and sixth coordination. Copper(II), nickel(H) and zinc(H) complexes of PHZ have been prepared. Copper(II) formed mono-and bis-complexes, whereas nickel(H) and zinc(II) formed only bis-complexes. The diamagnetic nickel(II) complexes are planar like the corresponding complexes of mesocyclic diamines, daco and dach. The copper(II) complexes differ appreciably from the mesocyclic diamine complexes of copper(II). Zinc (II) formed tetra-hedral complexes with two monodentate PHZ ligands and anions in the first coordination sphere. The structures of the complexes have been assigned by analysis of their spectral, magnetic and conductance data. The thermogravimetric studies of the complexes are also reported and discussed.
Photoreaktionen 2.2'-dihalogensubstituierter Benzoinether und Benzildimethylmonoketale in Lösung1 / Photoreactions of 2,2'-Dihalogen Substituted Benzoin Ether and Benzildimethylmonoketals in Solution1
Authors: Bak Claudia , Praefcke Klaus 
Published: February 2015

Abstract
The synthesis of α,α'-dihalogenated benzoin ether 6 and benzildimethylmonoketals 7 are discribed. Their reaction behavior under UV irradiation and electron impact conditions are discussed in comparison with those of arylesters 1 of seleno and thiobenzoic acid. The photoproducts of 6 and 7 are separated and identified with help of column or vaporphase chromatography. Photoinduced α-cleavages of 6 and 7 produce 2-halogenbenzoyl radicals 9 and a-monomethoxybenzyl radicals 10 or α,α-dimethoxybenzyl radicals 15 resp., which undergo four different stabilization reactions under formation of 1) 2-halogenbenzaldehydes 12 from 9 by hydrogenabstraction, 2) 2,2'-dihalogenbenzils 11 and 1,2-di(2-chlorophenyl)-1,2-dimethoxyethan (13) via dimerization of 9 or 10 resp., 3) methylesters 16 of 2-halogen-benzoic acids by β-elimination of methylradicals from 15, and 4) 2-halogenacetophenones 17 via combination of 9 with methylradicals from 15. In addition to these photoproducts 2-phenylbenzoic acidester 18, benzaldehyde (19), and acetophenone (20) are formed by photosubstitution of halogens in benzaldehydes 12 as well as in acetophenones 17 against hydrogen and in benzoic acid-esters 16 against phenyl resp. Independent photoexperi-ments prove 1) the formation of 2-phenylbenzoic acidester 18 by halogen-phenylreplace-ment in 16 and 2) that chlorine is easier than bromine, both in ortho-position to a carboxyl function, substituted by phenyl. No photoproducts {e.g. 8 or 14) are formed by substitution of halogen in the 2-halogenbenzoyl part of a-cleavage against neither a-monomethoxybenzyl nor a,a-dimethoxybenzylradicals resp. as expected like the photoinduced formation of selenoxanthones or thioxanthones 2 from selenol-or thiolesters 1.

Das Tricarbonyl-eisen-cycloheptatrienid-Anion [C7H7Fe(CO)3]–: η3-Allylanion- oder η4-Butadienkomplex? / The Triearbonyl Iron Cyeloheptatrienide Anion: η3-Allyl Anion or η4-Butadiene Complex?
Authors: Hofmann Peter 
Published: February 2015

Abstract
Molecular orbital calculations for [C7H7Fe(CO)3]-predict a η3 -allyl anion Fe(CO)3 complex with un-coordinated diene part of the C7H7 ligand to be more stable than the alter-native η4 -butadiene Fe(CO)3 form, the cyclopolyenyl ligand being nonplanar in either case. The tiny energy difference between both coordination modes accounts for the observed high fluxionality of the anion.

Published: February 2015

Abstract
(NSOF)2(CH3NSO2) 2a reacts with methanol to give sulfuric acid, aminosulfuric acid and SO2(NHCH3)2 as final products. The primary reaction was studied by 1H and 19F NMR spectroscopy. A 1:1 adduct 2a · CH3OH (=3) and a monosubstituted product which has the formula (NSOF)(NSOOCH3)(CH3NSO2)4 were detected to be intermediates.
As 2 a is chiral, the reaction with racemic butanol-2 proceeds via diastereomeric inter-mediates which were identified by their 19F NMR spectrum.
The reaction pattern of 2a is explained.
Molekulare Reaktionen in kalten Methan-Wasser-Plasmen und die Wirkung von UV-Bestrahlung / Molecular Reactions in Cold Methane-Water Plasma and the Effect of UV Irradiation
Authors: Simionescu Cr. , Dumitriu S. , Bulacovschi V. , Popa V. I. , Simionescu B. 
Published: February 2015

Abstract
After passage of methane-water mixtures through the state of a cold plasma, numerous products were identified, especially aldehydes, ketones, alcohols and acids. Their concentration was dependent on the methane/water ratio. Irradiation with UV light during or after the process gave transformations of the above compounds to more complex combinations. For the formation of ketones, aldehydes, alcohols and acids a detailed mechanism is proposed.

It crystallizes in the orthorhombic space group Pnma with lattice constants a = 1212.9, b = 1910 and c = 610.2 pm. The mean value of bond length from antimony to the terminal chlorine atoms is 235.5 pm, to the bridging chlorine atoms 280.0 pm and the averaged Sb-C distance is 213.3 pm.
The second form [(CH3)4Sb]+[SbCl6]- is an ionic one and crystallizes in the triclinic space group P1̅ with lattice constants a = 715.6, b = 744.2, c = 1415.2 pm, a = 90.01, β = 93.39 and γ = 106.4°. The mean values of bond lengths are Sb-C 211.5 pm and Sb-Cl 238.2 pm. The tetrahedrical as well as the octahedrical coordination polyhedra are only slightly distorted.

Abstract
The complexing of thallous ions (T1+), with the crown ether dibenzo 18 crown-6 poly-ether (DB) has been studied by NMR, fluorescence, and pulse radiolysis techniques. NMR data show a strong interaction of the T1+ ions with the aromatic moieties. This is also illustrated by a static quenching of the aromatic fluorescence by Tl+ . The rates of reactions of T1+ with hydrated electrons eaq- and pyrene excited singlet states are decreases on complexing the ion by the crown ether.
