    Notes: Summary In vitro hippocampal slices were prepared from control and commissural-kindled rats and the inhibitory processes of the dentate granule cells were assessed using paired perforant path stimulation. An early (20 ms) Cl--dependent and a late (200 ms-8 s) Cl--independent inhibition were shown to be present in the dentate. Enhancement of the late Cl--insensitive inhibition was observed following the establishment of commissural kindling and persisted for periods of up to eight weeks following the last seizure.

    Notes: Abstract Determinations of C3, C4, and C5 concentrations by radial immunodiffusion, and assays for the activation products of C3, C3c and C3d by counter-immunoelectrophoresis, were performed on 80 infants. Seven nonbacteremic preterm infants with necrotizing enterocolitis (NEC) or probable NEC (PNEC) were found at the time of diagnosis to have a significantly lower mean concentration of C3 (P〈0.05, 1-tailed) without C3 activation when compared to other noninfected preterm infants. Ten full-term and 63 preterm infants were studied prospectively during the first days of life, and were then followed for the postnatal development of localized or systemic infection. Assays for the detection of C3 activation products were negative in all these infants. Four preterm infants who developed PNEC after 5 or more days without clinical illness had low original concentrations of complement components. The pathogenesis of NEC may not involve primarily complement activation, and susceptibility to this condition may be related to pre-existing deficiencies in complement component concentrations relative to gestational age, or to defective activation of C3 in the presence of certain bacterial species and strains.

    Description / Table of Contents: Résumé Aleochara bilineata (Gyllenhal) [Coleoptera: Staphylinidae] est un prédateur et un parasite courants de la mouche des racines [Diptera: Anthomyiidae] dans les cultures commerciales et les jardins potagers. Pour évaluer l'activité de dissémination deA. bilineata dans les jardins potagers, on a lâché des coléoptères marqués à raison de 0 et de 1000 en 1987, et de 0, 250, 500, et 1000/jardin potager/semaine en 1988. Trois pour cent des coléoptères ainsi marqués ont été recapturés dans les jardins potagers d'origine. Les populations naturelles deA. bilineata sont très faibles dans tous les jardins potagers et on ne constate aucune augmentation décelable de 1987 à 1988. Les recaptures sont proportionnelles aux taux de lâchers. On n'observe aucune différence significative dans les taux de recapture entre les sexes. Les recaptures et les distributions non uniformes deA. bilineata marqués dans les jardins potagers révèlent qu'ils ont pu voler au moins à 5 km de distance dans les conditions urbaines et choisir certains jardins plutôt que d'autres comme emplacements propices à l'accouplement, la quête de nourriture et l'oviposition.
    Notes: Abstract Aleochara bilineata (Gyllenhal) [Coleoptera: Staphylinidae] is a common predator and endoparasite of root maggot [Diptera: Anthomyiidae] in both commercial crops and home gardens. To test dispersal activity ofA. bilineata in home gardens, marked beetles were released at rates of 0 and 1,000 in 1987 and 0, 250, 500, and 1,000/gardens/wk in 1988. Three percent of marked beetles were recaptured in release gardens. NaturalA. bilineata populations were very small in all gardens, and there was no detectable increase from 1987 to 1988. Recaptures were proportional to release rates. There was no significant difference in recapture rates between sexes. Recaptures and non-uniform distributions of markedA. bilineata in control gardens revealed that they were capable of flying at least 5 km under urban conditions, and of selecting particular gardens as suitable mating, foraging, and oviposition sites.
