    Immunological and virological characterization of improved construction of recombinant vaccinia virus expressing rinderpest virus hemagglutinin (1991)

    Notes: Summary We constructed a recombinant vaccinia virus (RVV) expressing rinderpest virus (RPV) hemagglutinin (H) by modifying the promoter region of the original RVV. The promotor region was modified at three points, i.e., an outframe ATG was eliminated, the sequence between the promoter and initiation codon was shortened and the base sequence just upstream of the initiation codon was changed. As compared with the original RVV, the modified RVV was found to produce a remarkably large amount of H protein in infected rabbit kidney cells cultured in vitro and to induce high titers of anti-RPV-H antibodies in rabbits. The median protective doses in rabbits of the modified and of the original RVVs were 102 pfu and 103.5 pfu, respectively, indicating that the modified RVV was at least 10-times more effective in protection than the original. The neurovirulence of the modified RVV and the parental LC16mO strain was roughly at the same level, and was much lower than that of WR strain. The modified RVV was as heat-stable as the original one. These results indicate that the modified RVV could be a candidate rinderpest vaccine for further examinations including cattle.

    Description / Table of Contents: Zusammenfassung Eine zuverlässige und empfindliche Methode wurde entwickelt, um die Konzentrationen des hypnotischen Medikaments Triazolam in menschlichen Geweben, einschließlich fauler Gewebe bestimmen zu können. Die Methode besteht aus einer dreistufigen Flüssig-Flüssig-Extraktion, einem Clean up an Kieselgel und Gaschromatographie mit einem Stickstoff-PhosphorDetektor und einer Kapillarsäule. Als interner Standard wurde Estazolam benutzt. Die Eichkurve war im Konzentrationsbereich zwischen 1 ng/g und 1 gg/g linear, und die untere Nachweisgrenze betrug 0.5 ng/g. Es wurde eine forensische Untersuchung über die toxikologischen Effekte von Triazolam an faulem Gewebe durchgeführt.
    Notes: Summary A reliable and sensitive method has been developed to assess the concentrations of the hypnotic drug triazolam in human tissues, including putrefied tissues. The method involves a 3-step solvent extraction, cleanup on a silica gel column and gas chromatography using a nitrogen phosphorus detector and a capillary column. Estazolam was used as an internal standard. The calibration curve was linear over the concentration range 1 ng/g1 gm/g and the lower limit of detection was 0.5 ng/g. A forensic study was performed on the toxicological effects of triazolam using putrefied tissues.

    Photofragmentation of cluster ions: the visible photoabsorption spectrum of Ar2N 2 + (1991)

    Notes: Abstract The absolute cross section for photodissociation of Ar2N 2 + was measured as a function of wavelength in the 470–550 nm range. A structureless broad band was observed; the cross section has a maximum of ∼ 210 × 10−18 cm2 at ∼ 500 nm. The measurement of the photofragment time-of-flight spectrum shows that(1) N 2 + , Ar+ and Ar 2 + are produced in the photodissociation of Ar2N 2 + in the wavelength range studied, and that(2) the observed visible absorption band is ascribable to a parallel-type transition of Ar2N 2 + , which possibly retains a linear geometry.

    Determination of kerosene and light oil components in blood (1991)

    Notes: A sensitive and rapid method to analyse fuel components in blood from rats exposed to kerosene or light oil vapour was developed by making use of capillary gas chromatography/mass spectrometry. The aliphatic hydrocarbons with carbon numbers 8-10 and aromatics such as toluene, xylene, 3- and 4-ethyltoluene and trimethylbenzenes were clearly detected in blood from rats exposed to kerosene or light oil vapour, using the head-space method combined with the salting-out technique. The concentration ratio of pseudocumene to toluene in blood exposed to light oil was higher than that in the case of exposure to kerosene. The lower limits of detection were 50 pg and 1 ng in toluene and pseudocumene, respectively. Our suggestion is that this method is useful in forensic investigations to detect fuel components in blood and for the purposes of differentiating kerosene and light oil in blood tissues.
