    Description / Table of Contents: Résumé Les lames des dernières vertèbres lombaires ont été réséquées sur cinq cadavres dans les quatre heures suivant la mort. Un court tube de caoutchouc a été inséré entre les racines nerveuses et le disque lombaire; la tension a été ensuite enregistrée grâce à des capteurs de pression transistorisés. Les stress angulaires exercés sur les racines lombaires lors de la recherche des signes de tension correspondent aux résultats fournis par l'expérience clinique.
    Notes: Summary The laminae were removed from the lower lumbar spines of five cadavers within four hours of death. A short length of rubber tube was inserted between the nerve roots and the lumbar disc and the tension monitored using semiconductor pressure transducers. The angulatory stresses exerted on the lumbar nerve roots during tension sign tests were found to correspond to clinical experience.

    Notes: Abstract Modification of an electroporation buffer using Ca(NO3)2 and elevated pH (9–10) appeared to have a favorable effect on gene transfer to creeping bentgrass (Agrostis palustris Huds.) Penncross protoplasts, resulting in an increase in the transformation frequency of about twofold. Following electroporation with the plasmid pARK22 containing the bar gene, a total of 278 bialaphos-resistant cell colonies were obtained from four experiments. The bialaphos-resistant regenerants proved to be transgenic by Southern hybridization of the amplified DNA. All the tested transgenic plants showed herbicide (HERBIE) resistance at the field rate of 0.5–1% (vol/vol). Ammonia contents in leaves after spraying with the herbicide increased less in transgenic plants than in untransformed control plants.

    Description / Table of Contents: Verbindungsbildung im System PbGeO3—Pb5Ge3O11Die Verbindungsbildung im System PbGeO3—Pb5Ge3O11 wurde mittels Thermoanalyse und Hochtemperatur-Röntgenbeugung untersucht. Neue Modifikationen des PbGeO3 und Pb5Ge3O11 wurden durch gleichzeitige Hydrolyse von Blei- und Germanium-alkoxiden dargestellt. PbGeO3 hat eine hexagonale Einheitszelle mit a = 15,573 und c = 7,240 Å und Pb5Ge3O11 besitzt eine orthorhombische Kristallstruktur mit a = 5,081, b = 7,301 und c = 8,817 Å. Sie werden in die bekannten monoklinen und hexagonalen Modifikationen bei 575 bis 610°C bzw. 410 bis 450°C umgewandelt. Eine Verbindung der Zusammensetzung Pb3Ge2O7 wird nicht bestätigt. Die Strukturen der Germanatgruppen in den Bleigermanaten werden auf der Grundlage von IR-Daten diskutiert.
    Notes: Compound formation in the system PbGeO3—Pb5Ge3O11 was studied by thermal analysis and high-temperature X-ray diffraction. New modifications of PbGeO3 and Pb5Ge3O11 were prepared by the simultaneous hydrolysis of lead and germanium alkoxides, followed by washing and drying; the former has a hexagonal unit cell with a = 15.573 Å and c = 7.240 Å, and the latter has an orthorhombic crystal structure with a = 5.081 Å, b = 7.301 Å and c = 8.817 Å. They are transformed to the known monoclinic and hexagonal modifications at 575 to 610°C and 410 to 450°C, respectively. No compound of Pb3Ge2O7 was confirmed. The structures of germanate groups in the lead germanate compounds are discussed on the basis of the infrared spectral data.
