    Notizen: Summary Soft winter wheat lines were crossed with Agropyron intermedium, A. elongatum and A. trichophorum using pollen from single plants of Agropyron spp. to pollinate wheat spikes. Not only species but also individual plants within varieties of Agropyron species differed in percent seed set with a wheat genotype. In two arrays of crosses between two phenotypically different plants of A. elongatum and nine wheat lines, one Agropyron plant gave higher seed set (overall=27.1%) than the other (overall=3.7%). The differences were significant in seven of the nine cross combinations. Results are consistent with the hypothesis that these two plants differ in their crossability as pollen parents with wheat, and suggest the possibility of occurrence of crossability genes in wheatgrasses. The success rate of hybrid embryo rescue was higher (87.5%) with cold treatment (4°C) than without cold treatment (75.0%) of excised embryos on culture media. Results underscore the significance of genotype of the alien species for crossing with low crossable wheats, and of the physical factors for improving embryo rescue in wide crosses.

    Notizen: Abstract Twenty-two cultivars and lines of winter and spring wheat (Triticum aestivum L.) were studied, most for the first time, for their anther culture response. The response was genotype dependent. Plants grown in the field gave higher callus induction frequency than those grown in the greenhouse and the controlled environment chamber. Donor plants grown in a season of low drought stress as compared to a season of severe drought stress resulted in a higher frequency of callus induction. Spherical microcalli were observed in two wheat genotypes in some of only those anthers that were placed with only one loculus in contact with the medium. Wheat lines that were more responsive to anther culture were identified.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Die Amputationsháhe bei schwerer arterieller Verschlußkrankheit der Beine ist umstritten. Wir berichten über 230 Amputationen an der unteren Extremität bei 197 Patienten in den Jahren 1978–1980. 40% wurden distal des Kniegelenkes durchgeführt, davon konnten 72% zur Abheilung gebracht werden. 28% mußten nachamputiert werden (31% der Zehenamputationen, 22% der Mittelfußamputationen, 28% der Unterschenkelamputationen). Wegen der Vorteile bei der Rehabilitation sollte statt der grundsätzlichen Oberschenkelamputation eine möglichst periphere Amputation versucht und das Risiko einer Nachamputation in Kauf genommen werden.
    Notizen: Summary The level of amputations for arterial occlusive disease of the leg is often discussed. We reviewed 230 amputations at the lower extremity performed on 197 patients during the years 1978–1980: 40% were distal to the knee joint, 72% of which healed; 28% had to be reamputated at a more proximal level (31% of the toe amputations, 22% of the metatarsal or transmetatarsal amputations, and 28% of the below knee-amputations). Instead of general above-knee amputation, a more distal amputation should be tried.
