    Notes: Background and objective In previous studies we have generated mimotopes of Bet v 1, the major birch pollen allergen, by biopannings of phage-display random peptide libraries. In the present study, we analysed the humoral and cellular immune response to Bet v 1-mimotopes.Methods The mimotope CFPYCYPSESA, designated Bet mim 1, was used for intraperitoneal immunizations of BALB/c mice in phage-displayed form. For examination of the humoral immune response, enzyme-linked immunosorbent assay (ELISA) experiments were applied. Stimulation capacities were investigated in cultured mouse splenocytes and in humoral Bet v 1-specific T cell clones.Results We demonstrated that the Bet mim 1-induced murine antibody response against Bet v 1 was predominated by the IgG1 isotype. In these mice only the phage-displayed mimotopes, but neither the allergen nor the synthetic Bet mim 1-mimotopes were able to stimulate proliferation of cultured splenocytes. Using Bet v 1-specific T cell clones of allergic patients, phage-displayed and synthetic mimotopes were unable to stimulate T cell proliferation. Moreover, tolerance induction to Bet v 1 in mice by intranasal administration of Bet mim 1-phages or Bet mim 1-peptide failed.Conclusion Taking these results together, our data indicate that Bet mim 1 mimics a Bet v 1-epitope on the B cell but not on the T cell level. We suggest that the phage itself is responsible for the recruitment of T cells providing bystander help in the formation of a mimotope-specific humoral response.

    Description / Table of Contents: Abstract The crystal structure of TaNiGe has been examined by means of a Fourier-Synthesis. TaNiGe was found to be isotypic with TiNiSi (ordered PbCl2-type) already described byClara B. andD. P. Shoemaker The lattice parameters of the followingE-phases have been determined: ZrPdSi, ZrPtSi. ZrPtGe, ZrCuSi, ZrCuGe, HfFeSi, HfCoSi, HfCoGe, HfNiSi, HfNiGe, HfCuSi, TaNiGe, NbNiSi, TaFeGe and TaCoGe.
    Notes: Zusammenfassung Die Kristallstruktur von TaNiGe wird mit Hilfe einer Fourier-synthese bestimmt und als geordneter PbCl2-Typ erkannt. Damit wird die Struktur der E-Phasen, welche vonClara B. undD. P. Shoemaker an TiNiSi bereits ermittelt wurde, bestätigt. Folgende neue E-Phasen werden aufgefunden, die Gitterparameter ermittelt: ZrPdSi, ZrPtSi, ZrPtGe, ZrCuSi, ZrCuGe, HfFeSi, HfCoSi, HfCoGe, HfNiSi, HfNiGe, HfCuSi, TaNiGe. Ferner werden die Gitterparameter der schon bekanntenE-Phasen NbNiSi, TaFeGe und TaCoGe bestimmt.

    Description / Table of Contents: Abstract Powder of Zr-carbohydride containing about 20 atomic % H, prepared out of ZrC∼0,6, has been examined by neutron diffraction a superstructure being observed according:a zrC 0,6H0,4=2a zrC 0,6. The structural type can be explained by partial ordered filling of the tetrahedral sites.
    Notes: Zusammenfassung Ein Zirkoniumcarbohydrid-Pulver, das aus ZrC∼0,6 hergestellt wird und etwa 20 At% H enthält, wird mittels Neutronenbeugung untersucht. Die dabei beobachtete Überstruktur — der Gitterparameter der kfl. Zelle des Carbohydrids ist gleich dem doppelten von ZrC0,6 bzw. der erneut dehydrierten Probe —läßt sich durch teilweise geordneten Einbau der H-Atome auf Tetraederpositionen deuten.
