    Notes: Cestode fish parasites were studied in 569 fish of 13 species, comprising 72 specimens of Hyperoplus lanceolatus caught between April and July 1987 and 497 other fish caught between December 1986 and March 1987 at 42° 45′ N, 9° 26′ W (Table I). Bothriocephalus was found for the first time in H. lanceolatus, though its prevalence was very low. The presence of these larvae in a species that forms part of the turbot's Scophthalmus maximus food chain suggests that they may infect the turbot via H. lanceolatus as well as via copepods.

    Notes: Abstract Scanning electron microscopy (SEM) makes possible an adequate description of the complex cephalic structure of Cristitectus congeri. Valuable data are provided for the definition of the genus, including the presence of eight cephalic furrows, four well-defined external papillae and four small internal papillae. Medial to the small labia are four very prominent sublabia with their corners fused with the labium proper; between the two labia on either side is a prominent pseudolabium with a conical protuberance whose medial face merges with the corresponding lateral wall of the buccal cavity. The males have 10 pairs of caudal papillae (four pre-anal and six post-anal) and two phasmids.

    Notes: Abstract The effect of the adult worms and migrating L1 larvae of Trichinella spiralis on the production of specific IgE antibodies was determined in BCF1 mice. To achieve this, we combined the effect of two anthelminthics: thiabendazole, to produce chemosterilization of adult females, and napthalophos, to expel adult worms from the intestine of infected mice on the desired day. Our results demonstrate that when the natural route of infection is used the production of IgE antibodies is not dependent on the infection dose or the number of migrating L1 larvae, and that both intestinal worms and migrating L1 larvae contribute to the production of reaginic antibodies. In addition to this, an extended period of antigenic stimulation (10–12 days) is required for the induction of a detectable, specific IgE response by adult worms. Finally, our results seem to indicate that although the effects of adult worms and migratory L1 larvae on the IgE production are not additive, the presence of adult worms in the intestine of mice may stimulate a secondary exposure to common antigens released by the migrating L1 larvae.

Die Struktur von Bis-{N-[2-(2-pyridyl)äthyl]-salicylideneiminato}nickel(II). Trihydrat wurde röntgenographisch bestimmt. Der Komplex kristallisiert triklin in der Raumgruppe P1 mit den Gitterkonstanten a = 13,055(4) Å, b = 13,097(6)Å, c = 16,189(5) Å, α = 102,92(3)°, β = 99,80(3)°, γ = 90,42(3)° und Z = 4. Eine Least-squares-Verfeinerung führte zu einem R-Wert von 0,047. Das Molekül ist nicht zentrosymmetrisch, da die zwei dreizähnigen Liganden eine meridionale Konfiguration um das oktaedrisch koordinierte Nickel(II) annehmen.
    Notes: Nickel(II) complexes with N-2-(2-pyridyl)ethyl-ring substituted salicylideneiminatos have been synthesized by an electrochemical procedure using a sacrificial anode in non-aqueous solution of the corresponding ligand. The structure of bis{N-[2-(2-pyridyl)]-salicylideneiminato}-nickel (II) trihydrate has been determined by X-ray diffraction. Crystals are triclinic, space group P1, with four formula units in a cell of dimensions a = 13.055(4) Å, b = 13.097(6) Å, c = 16.189(5) Å, and α = 102.92(3)°, β = 99.80(3)°, γ = 90.42(3)°. Full matrix least squares refinement on R converged with a conventional agreement factor of 0.047. The molecule is non-centrosymmetric with two terdentate ligands in a meridional configuration around octahedral nickel(II).
