    Notizen: Abstract Eighty-four strains of Neisseria gonorrhoeae isolated in Munich between January 1987 and June 1988 were characterized in terms of their plasmid content, protein I serovar and susceptibility or resistance to four antimicrobial agents. Eighty two percent of the strains belonged to serogroup 1B, the three most prevalent serovars being 1B-1, 1B-2 and 1B-6. Among the serogroup 1A strains, 1A-2 was the commonest serovar. Fourteen strains (16.7%) lacked the 2.6 Md cryptic plasmid, although two of these strains contained the conjugative gonococcal plasmid. Although some degree of resistance to penicillin and tetracycline was noted, all the strains were sensitive to spectinomycin and cefotiam.

    Detection of a novel “cryptic” plasmid of about 7.8 MDal in a non-penicillinase-producing Neisseria gonorrhoeae isolate from Munich (1990)

    Notizen: Abstract A novel plasmid of about 7.8 megadaltons (MDal) could be detected in a non-penicillinase-producing Neisseria gonorrhoeae strain isolated in Munich in 1987. As the strain showed no resistance against commonly used chemotherapeutic agents, at present the plasmid must be described as phenotypically “cryptic”.

    Notizen: Abstract The activity concentrations of 99mTc-HMPAO in brain after intravenous injection were evaluated in 25 patients using SPECT. With additional first pass studies of heart and brain with the short lived isotope 195mAu, the cardiac output and the mean cerebral transit times of the patients were measured a short time before the HMPAO injection. The time dependence of 99mTc-HMPAO activity in the brain was registered during the first 5 min after injection over both hemispheres. Using a simplified three compartment model it was possible to calculate the mean retention fraction of HMPAO in brain from the time activity curves. It could be shown that the regional cerebral blood flow in ml/min per 100 g can be calculated from the activity concentration of HMPAO in the brain, the cardiac output and the retention fraction. In 15 of the 25 cases the rCBF was measured using the planar 133Xe inhalation method as a reference. We found a significant correlation between the mean hemisphere CBF from our method and the mean hemisphere grey matter CBF from the Xenon method with a correlation coefficient of 0.73.
