    Lectin histochemistry of canine polyglucosan bodies (1987)
    Springer
    Acta neuropathologica 73 (1987), S. 177-180 
    Details
    ISSN: 1432-0533
    Schlagwort(e): Lectins ; Polyglucosan bodies ; Dog

    Thema: Medizin
    Notizen: Summary Lectin histochemistry was investigated to identify sugar residues of the polyglucosan bodies of canine brain, spinal cord and caecum. The polyglucosan bodies in the brain and spinal cord stained with concanavalin A (ConA) but not with soybean agglutinin, wheat germ agglutinin, peanut agglutinin,Dolichos biflorus agglutinin,Ricinus communis agglutinin andUlex europaeus agglutinin. Caecum, polyglucosan bodies, however, did not stain with any of the seven lectins employed. After periodate oxidation, paradoxical ConA staining was observed in the polyglucosan bodies of the brain, spinal cord and caecum. These results indicate that polyglucosan bodies contain mannose and glucose residues and suggest that the component of polyglucosan bodies is partially derived from rough endoplasmic reticulum, the Golgi apparatus and hypolemmal cisternae.

    Immunoreactivity of canine and feline polyglucosan bodies for monoclonal antibody against human polyglucosan (1990)
    Springer

    Notizen: Summary With the use of monoclonal antibodies, raised against the human polyglucosan, positive staining of polyglucosan bodies (PGB) was detected in the brain, spinal cord and cecum of aged dogs. PGB in feline brain were also positively stained with these antibodies. These findings indicate that animal PGB share common antigenicity with human PGB.

    Polyglucosan bodies in the brain of a cow (1994)
    Springer
    Acta neuropathologica 88 (1994), S. 75-77 
    Details
    ISSN: 1432-0533
    Schlagwort(e): Polyglucosan bodies ; Cow
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Abstract Polyglucosan bodies (PGBs) in the brain of a 12-year-old Holstein cow exhibiting no signs of neurological abormality were examined by light and electron microscopy and immunohistochemistry. PGBs were disseminated throughout the brain, especially in the pallidum, thalamus and cerebellum. Cow PGBs were found in the neuronal perikaryon and in the neuropil. These were round, slightly to severely basophilic, and were strongly positive for the periodic acid-Schiff reaction. The cow PGBs were immunoreactive for monoclonal antibodies raised against human polyglucosan. Electron microscopic analysis revealed that they were composed of branching filaments, glycogen granules and electrondense meterial. These findings indicate that cow PGBs closely resemble human or canine PGBs in Lafora's disease and PGBs found in aged animals that have been reported previously.

    Polyglucosan bodies in the digestive tract of the aged dog (1983)
    Springer
    Acta neuropathologica 60 (1983), S. 297-300 
    Details
    ISSN: 1432-0533
    Schlagwort(e): Polyglucosan bodies ; Lafora-like bodies ; Aging ; Smooth muscles ; Digestive tract ; Dog
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary In our recent studies on aging phenomena in animals, polyglucosan bodies (PGB) were found within the smooth muscle in the digestive tract of aged dogs without neurologic signs. PGB were basophilic, round, or oval bodies which appeared to have a homogenous or concentric shape. Their histochemical properties were characterized by the presence of glucose polymers (polyglucosan). Electron microscopy revealed that PGB were composed mainly of irregularly clustered, short branching filaments measuring about 90 Å in width. PGB were histochemically and ultrastructurally identical to the previously reported Lafora-like bodies in the CNS of aged dogs. PGB were found in all aged dogs and were disseminated throughout the digestive tract, especially in the cecum.

    Evaluation of the influence of the base material loaded with hydrous zirconium oxide gel on the retention behavior of disubstituted benzoic acids (1996)
    Springer
    Chromatographia 43 (1996), S. 79-81 
    Details
    ISSN: 1612-1112
    Schlagwort(e): Column liquid chromatography ; Hydrous zirconium oxide ; Porous polymer resin ; Silica gel ; ortho-Benzoic acid derivatives
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Summary Silica gel loaded with hydrous zirconium oxide (Zr-gel-S) has been prepared and the influence of the base material on the retention behavior ofo-phthalic acid on the hydrous zirconium oxide was evaluated. The retention behavior of the acid on the Zr-gel-S was compared with that on Zr-gel-5, the polymer-based Zr-gel. Comparable retention behavior,i.e. maximum retention in the vicinity of pH 6, which has been regarded as the equal adsorbic point, was observed for both types of Zr-gel, although there was a large difference in the retention times. The difference in retention on the two types of Zr-gel could be ascribed to nature of the base material. The results in this experiments showed, however, that the specific behavior at pH 6 was an essential characteristic of hydrous zirconium oxide and was not related to the influence of the base materials.

    Comparison of surface states of chemically modified silicas in aqueous acetonitrile and methanol (1991)
    Springer

    Thema: Chemie und Pharmazie
    Notizen: Summary The thermodynamic behaviour of n-alkylbenzenes on chemically modified silicas in reversed-phase liquid chromatography has been examined in acetonitrile-water and methanol-water systems. Plots of the thermodynamic parameters obtained against the organic solvent compositions indicate an interesting trend which implies that the surface states of the chemically modified silicas under the two eluent systems are different.

    Notizen: Summary A process to synthesize silica and titania as spherical packing materials has been investigated on the laboratory scale by the sol-gel method. The silica and titania obtained were tested under normal-phase separation conditions for comparison of their retention characteristics silica witha a commercial. The silica was found to be similar in its retention behaviour to the commercial silica. The titania showed basic properties and strongly retained acidic compounds.

    Micro high performance liquid chromatography of aliphatic amines by means of resonance raman detection (1987)
    Weinheim : Wiley-Blackwell

    ISSN: 0935-6304
    Schlagwort(e): Micro high performance liquid chromatography, micro-HPLC ; Resonance Raman detection ; Dabsylamide ; Chemistry ; Analytical Chemistry and Spectroscopy
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie
    Notizen: A micro high performance liquid chromatography coupled with a resonance Raman detection system is described. For highly sensitive Raman detection, aliphatic amines were derivatized with dabsyl chloride (4-dimethylaminoazobenzene-4′-sulfonyl chloride). The derivatives were separated on an ODS micro column (0.5 mm i.d. × 145 mm PTFE tube). Chromatograms were obtained by measuring the intensity of Raman scattering at 1136 cm-1 with the 488.0 nm line of an Arion laser. The lower detection limit was 1.5 ng and the RSD of relative peak height (n = 9) was 5.9% at 11 ng of methylamine derivative. Moreover, by stopping the flow of the micro HPLC system at the retention time of the individual derivatives, it was possible to measure their resonance Raman spectra.

    Surface chlorination of polypropylene film by CHCI3 plasma (1994)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 51 (1994), S. 2131-2137 
    Details
    ISSN: 0021-8995
    Schlagwort(e): Chemistry ; Polymer and Materials Science

    Thema: Chemie und Pharmazie , Maschinenbau , Physik
    Notizen: Polypropylene films were treated with the CHCI3 plasma, and their chemical composition was analyzed with XPS and ART IR spectroscopy. The CHCI3 plasma irradiation made polypropylene films hydrophilic. The advancing contact angle decreases from 95° for the untreated to about 73° for the CHCI3 plasma-treated films. In the CHCI3 plasma irradiation, the chlorination occurs, and C—Cl, C—Cl2, and C—Cl3 units are formed in the polypropylene films. Simultaneously with the chlorination, unsaturated units (C=C and conjugated C=C units) are formed from dehydrogen chlorination of the chlorinated products, but the oxygen incorporation into the films is low. The CHCI3 plasma is preferred in chlorination of polypropylene films to the CCl4 plasma. © 1994 John Wiley & Sons, Inc.
