    Notes: A patient is presented with the “flag sign” which was associated with episodic malnutrition in an alcoholic. Diminished hair diameter, flating and loss of normal cuticle were found in areas of depigmentation but were sometimes dissociated suggesting different mechanisms within the general terms of “malnutrition”.

    Notes: Conclusion A number of recent studies have been discussed which provide strong evidence that genetic and immunological factors are important in the pathogenesis of PSC. Current evidence suggests that PSC is, like primary biliary cirrhosis, an immunologically mediated disease [8]. It seems likely that the immunological destruction of the biliary system is triggered in genetically predisposed individuals by viruses or bacteria [8]. The association with ulcerative colitis may be explained by the passage of viral or bacterial organisms across the damaged colonic epithelial barrier into the systemic circulation. Further studies are needed to confirm this attractive hypothesis.

    Interactions between two neurons in contact chemosensilla of the grasshopper, Schistocerca americana (1990)

    Notes: Summary The tibial contact chemosensilla of Schistocerca americana contain several neurons, one of which responds to nicotine hydrogen tartrate and certain other compounds. The activity of this cell is sometimes briefly interrupted by the firing of a second cell in the same sensillum which usually only fires a few times in the first 500 ms of a stimulation. The evidence suggests that the nicotine-sensitive cell is directly inhibited by the activity of the second cell. Not all cells in the sensillum produce the same effect.

    A novel resin-filled ion-sensitive micro-electrode suitable for intracellular measurements in isolated cardiac myocytes (1990)

    Notes: Abstract A method for the manufacture of ion-sensitive micro-electrodes, which can be readily used with small single cells, is described in detail. A glass pipette with a tip size of 1 μm, essentially similar to those used as suction electrodes in whole-cell recording, when silanized and with its tip filled with a suitable ion-sensitive resin, producesan ion-sensitive electrode with fast electrical and chemical response times. These electrodes can be applied to the cell membrane of isolated myocytes and penetration achieved without cell damage, by the application of suction. For the estimation of intracellular ionic activities they can be used in conjunction with a separate conventional KCl-filled micro-electrode or a suction voltage electrode. The technique is illustrated by the measurement of intracellular Na+, Ca2+ and pH. It is possible that these electrodes can also be used to measure local changes in ionic activity in restricted areas.

    Olfactory sensitivity of gomphocerine grasshoppers to the odours of host and non-host plants (1990)

    Description / Table of Contents: Résumé Les réponses antennaires ont été examinées par électroantennogramme aux odeurs de plantes hôtes et non hôtes d'orthoptères Gomphocerinae de comportements alimentaires différents: Bootettix argentatus, monophage sur une dicotylédone, Larrea; Ligurotettix coquilletti, oligophage de dicotylédones; Cibolacris parviceps, polyphage; Chorthippus curtipennis, graminivore. Les types de réponse des quatre espèces étaient très voisins, mais les réponses aux odeurs de Larrea de B. argentatus et L. coquilletti, spécialistes de cette plante, étaient relativement plus fortes. Ces résultats suggèrent une similarité globale considérable dans la composition des populations de récepteurs olfactifs de ces quatre espèces d'orthoptères mais aussi une certaine spécificité pour les odeurs de la plante hôte au niveau antennaire.
    Notes: Abstract Antennal responses to host and non-host odours were recorded, using the electroantennogram technique, from four gomphocerine grasshoppers with different feeding habits: Bootettix argentatus (monophagous on Larrea, a dicotyledonous plant), Ligurotettix coquilletti (oligophagous on dicotyledonous plants), Cibolacris parviceps (polyphagous) and Chorthippus curtipennis (graminivorous). The patterns of responses across the plant odours were similar for all four grasshopper species, but there was a relatively greater response to the odour of Larrea in B. argentatus and L. coquilletti which specialise on this plant. This suggests that there is considerable overall similarity in the make up of the olfactory receptor populations of these four grasshoppers species, but that some specificity for hostplant odour does exist at the antennal level.

    Notes: Abstract High spin states of175, 176Pt have been populated in144Sm(35Cl,pxn) reactions at beam energies of 175–185 MeV. In-beamγ-ray spectroscopic techniques using the ESSA30 spectrometer array were adopted. Levels up to spin 26 in176Pt and tentatively up to spin 45/2 in175Pt have been identified. The data are interpreted within the framework of Cranked Shell Model calculations using the deformed Woods-Saxon potential and including monopole pairing.

    Description / Table of Contents: Résumé Les insecticides pyrethroïdes ont été utilisés pour lutter contre les pullulations d'araignées rouges. Cette note examine les réponses de Tetranychus urticae Koch et des prédateurs phytoseiidés résistants aux organo-phosphorés, Amblyseius fallacis Garman et Typhlodromus occidentalis Nesbitt, au fenvalerate (pyrethroïde) et à l'azinphosmethyl (organophosphate). Quelques essais avec du carbaryl sont indiqués. Une femelle adulte de T. urticae est placée sur une rondelle de feuille de Phaseolus vulgaris L. pulvérisée dans une tour de Potter. Les résultats sur la mortalité en fonction de la dose obtenus montrent une activité plus rapide du fenvalerate que de l'azinphosmethyl. Les DL50 du fenvalerate (0,056 et 0,051g AI/I) sont les mêmes à 24 et 48 h, tandis que l'azinphosmethyl montre une activité plus lente (DL50 de 0,72 et 0,38g AI/I à 24 et 48 h). La mortalité se partage entre la sortie de la rondelle et la mortalité in situ. Le fenvalerate provoque une plus forte répulsion que l'azinphosmethyl. Contrairement à l'azinphosmethyl le fenvalerate inhibe la production d'oeufs 60% et 20% d'inhibition à DL50 au bout de 24 h par rapport au témoin. Cette inhibition n'est pas permanente. Le carbaryl n'a pas d'effets inhibiteur ou acaricide à 1g AI/l. Les femelles adultes de T. urticae décèlent les résidus de fenvalerate sur les rondelles et pondent leurs oeufs sur les moitiés non traitées ou traitées à l'azinphosmethyl. Les Phytoseiides sont très sensibles aux résidus de fenvalerate. Après consommation d'oeufs traités, A. fallacis est incapable d'éviter des bandes gluantes. T. occidentalis décèle des traitements à 0,00005g AI/l en quittant les lames traitées par les bandes gluantes.
    Notes: Abstract The pyrethroid fenvalerate showed significantly faster activity against adult ♀ two-spotted spider mite Tetranychus urticae Koch c.f. azinphosmethyl using broad bean leaf discs sprayed in a Potter tower. LC50s for fenvalerate were similar at 24 and 48 hr (0.056 and 0.051g AI/1) while LC50s for azinphosmethyl were significantly different at 24 and 48 hr (0.72 and 0.38g AI/1, respectively). Mortality was partitioned to run-off and direct mortality. Fenvalerate showed an increasing contribution to mortality by run-off with increasing concentration. Increasing concentrations of azinphosmethyl had no effect on the proportion of T. urticae running off the discs. Fenvalerate inhibited egg production c.f. azinphosmethyl (60% and 20% inhibition respectively c.f. control after 24hr). The effect was not permanent. Carbaryl showed no acaricidal or inhibitory effects at 1g AI/1. T. urticae detected fenvalerate residues as reflected by choice of oviposition sites on untreated halves of leaf discs c.f. treated halves. Azinphosmethyl had no effect on oviposition preference. Phytoseiid mites were highly sensitive to fenvalerate residues. Predators moved off the test arena into sticky barriers after feeding on fenvalerate-treated eggs or walking on glass slides treated at 0.00005g AI/1.
