    Notes: Summary A mechanical obstruction was produced in the dog ileum, and four days later, loops of intestine above and below the occlusion were subjected to one hour's ischaemia. This led to widespread morphological and functional damage of the epithelium, indistinguishable from the response of the normal intestine. The recovery of the mucosa of both loops after the ischaemia followed exactly the same pattern as when there was no occlusion superimposed: The transport capacity for phenylalanine in vitro was entirely restored, whereas that of β-methyl-glucoside, together with oxygen consumption and lactate production, remained depressed; morphometric examination revealed that the recuperating mucosa had smaller villi, shorter crypts and smaller epithelial cells than the contiguous untouched tissue. These results suggest that the regenerative potential of the crypts could not be obliterated by one hour's ischaemia, either in the presence of a noxious obstruction fluid above the occlusion, or in the atrophic mucosa below it.

    Description / Table of Contents: Résumé Une occlusion mécanique de l'intestin grêle du rat a été produite 40 cm au-dessus de la valve iléo-caecale. Les animaux ont été sacrifiés le premier, deuxième et troisième jour post-opératoire, et l'état des anses intestinales a été comparé avec celui des anses témoins prélevées chez des rats non-traités. Comme paramètre de la fonction intestinale, nous avons mesuré l'absorption de phénylalanine par le tissu in vitro. Les résultats ont montré que la capacité absorptive de l'acide aminé, surtout en amont de l'occlusion, est abaissée par rapport aux anses témoins, et ceci déjà à partir du premier jour et progressivement jusqu'au troisième jour post-opératoire. En aval de l'occlusion la diminution de l'absorption est moins accentuée. Histologiquement, on observe une déformation des villosités au-dessus de l'occlusion, mais le recouvrement épithélial reste intact.
    Notes: Summary The rat intestine was mechanically obstructed 40 cm above the ileo-cæcal valve. The animals were sacrificed on the first, second and third postoperative day and the state of their intestines was compared with that of control loops taken from sham-operated rats. Intestinal function was determined by measuring the absorption of phenylalanine during incubation of intestinal ringsin vitro. The absorptive capacity was reduced, particularly above the occlusion, the decrease being progressive from the first to the third day. Below the occlusion the reduction was slighter. Histologically, deformation of the villi above the occlusion is observed, but the epithelial layer remains intact.

    Notes: Summary The inheritance of resistance to Russian wheat aphid Diuraphis noxia (Mordvilko), in two resistant barleys, Hordeum vulgare L., ASE/2CM//B76BB and ‘Gloria/Come’, was studied in the field and in the greenhouse. The resistant genotypes were crossed with susceptible genotypes ‘Esperanza’ and ‘Shyri’. Resistance reactions of F1, BC1, and F2 plants, and individual F2 plant derived F3 families indicated that resistance in each genotype was controlled by the same single dominant gene.

    Notes: Summary During the winters of 1990/91 and 1991/92, 181 accessions of Triticum dicoccon Schrank from the CIMMYT gene-bank were screened in the field for resistance to Russian wheat aphid, Diuraphis noxia (Kurdjumov). Accessions were sown in hill plots of 10 seeds and artificially infested with D. noxia at the two-leaf growth stage. Hills were visually assessed for damage at tillering, booting and heading. Entries differed significantly in their reaction to D. noxia, and severity of symptoms increased with time. Twenty four of the entries were highly resistant to the aphid. In winter 1991/92, 807 accessions of wild and cultivated wheats (26 species) and synthetic hexaploids were screened similarly for resistance to D. noxia. A large number of A-genome species were resistant, while few D-genome species were identified as resistant. These newly discovered sources of resistance can be used to expand the genetic base of resistance to D. noxia in both bread (T. aestivum L.) and durum wheats (T. turgidum L. convar. durum (Desf.) Mackey).
