    Notizen: Abstract The pathogenesis of delayed sequelae of carbon monoxide (CO) exposure is still unknown. We repeatedly examined a 55-year-old woman with the interval form of CO poisoning, using proton magnetic resonance spectroscopy (MRS). When the clinical picture was severe, MRS revealed markedly lowered N-acetyl-asparatate (NAA)/creatine and phosphocreatine (Cr) ratio and slightly increased choline containing compounds (Cho)/Cr ratio. Subsequently, NAA and Cho/Cr ratio tended to return to normal, reflecting clinical improvement. Proton MRS shows the previously unrecognised neuronal activity in CO poisoning and precisely reflects the severity of symptoms. We stress the superiority of proton MRS over the conventional radiological examinations in CO poisoning.

    Notizen: Abstract The distribution of vinyl groups in polystyrene/poly(styrene-divinylbenzene) (PS/P(S-DVB)) composite microspheres produced by seeded copolymerization of S and DVB in the presence of 2.1-μm monodisperse PS seed particles was estimated from the amount detected with bromine titration method as a function of the reaction time under various conditions.

    Preparation of micron-size monodisperse polymer microspheres having cationic groups (1992)
    Springer
    Colloid & polymer science 270 (1992), S. 733-737

    ISSN: 1435-1536
    Schlagwort(e): Polymeremulsion ; microsphere ; chloromethylgroup ; polyamine ; cationicgroup ; dispersionpolymerization ; seededpolymerization

    Notizen: Abstract Micron-size monodisperse crosslinked polymer microspheres having chloromethyl groups were prepared by seeded copolymerization of styrene, divinylbenzene, and chloromethylstyrene in the presence of 2.1-μ monodisperse polystyrene seed particles produced by dispersion polymerization. The modification reaction of chloromethyl groups on the surfaces with polyamines such as triethylenetetramine and ethylenediamine was carried out. From the measurements of ξ potential and the amount of chloride ion released, the introduction of a large number of cationic groups at the surfaces was confirmed.
