    Description / Table of Contents: Zusammenfassung 1. Schwärmen ist häufigen im Frühsommer als im Spätsommer, aber diese Verteilung stellt wahrscheinlich nicht wirklich jahrzeitliche Schwankungen in der Intensität der Bedingungen dar, die die Bienenvölker zum Schwärmen veranlassen. Das Auftreten von Vorbereitungen zum Schwärmen in Völkern, die schliesslich doch nicht schwärmen, und das Vorkommen von leeren Weiselnäpfchen in Völkern, die sich nicht zum Schwärmen vorbereiten, zeigen einen späteren Höhepunkt, der im allegmeinem gut mit dem Höhepunkt von Pollen- und Nektar-produktion in der Natur zusammenfällt. 2. Die Verringerung in der Brutaufzucht in den Völkern am Ende der Jahreszeit findet ungefähr zur selben Zeit statt, wie die Verminderung in der Schwarmtendenz und auch der verfügbaren Bienenweide. In den Völkern unter Beobachtung verringerte sich die Brutaufzucht nicht entgültig vor diesem Zeitpunkt, mit Ausnahme von Völkern in welchen Königinnenzucht stattfind. Im allgemeinen trat diese Verringerung erst ein, nachdem die Königinnenzucht angefangen hatte; es hätte daher eine Folge der Königinnenzucht sein können, aber in den meisten Fällen konnte dies nicht die Ursache sein. Mehr Völker begannen Königinnen zu züchten wenn ihre Brut zunahm, als wenn sie sich verminderte. Die Zeit der Brutzucht scheint nicht von der Tageslänge abzuhängen, da die Beziehungen dieses Faktors zur Brutzucht in sub-tropischen Klimaten die entgegengesetzten sind zu denen in gemässigten Klimaten. 3. Eine Anzahl von Völkern begann die Koniginnenzucht bevor sie ihre Höchstgrösse erreicht hatten, während andere nicht einmal nach diesem Zeitpunkt anfingen. Beweis dafür, dass Königinnenzucht anfängt wenn das verhältniss von Brut zu Bienen unter eine kritische Höhe fällt wurde nicht gefunden. 4. Obwohl es scheint dass die Schwarmzeit grösstenteils unmittelbar durch die Aussenfaktoren festgelegt wird, kann die Möglichkeit doch nicht ausgeschlossen werden, dass es zum Teil auch durch einen Zyklus von physiologischen Veränderungen innerhalb der Völker beeinflusst wird.
    Abstract: Résumé 1. L'essaimage actuel se produit plus fréquemment au début qu'à la fin de l'été, mais sa répartition au cours de la saison ne représente pas vraiment les variations d'intensité des facteurs induisant l'essaimage. Le degré de préparation de l'essaimage dans les colonies qui ne pratiquent pas l'essaimage actuel, et le nombre de départs de cellules de reines dans les colonies qui ne se préparent pas à l'essaimage présentent un maximum plus tardif qui, en moyenne, coïncide bien avec la période de plus grande abondance de nectar et de pollen dans la nature. 2. Le déclin automnal de l'élevage du couvain dans les colonies se produit à peu près en même temps que diminue la tendance à l'essaimage et la possibilité de butiner. Dans les colonies observées, l'élevage du couvain ne décroît pas de façon continue avant cette période, sauf chez quelques-unes de celles où l'élevage des reines se produit. Généralement, ce déclin survient seulement après que l'élevage des reines a commencé; ainsi, il peut être une conséquence de l'élevage des reines, mais, dans la plupart des cas, ne peut être sa cause. La plupart des colonies commencent à élever des reines plutôt quand leur couvain croît que lorsqu'il décroît. La période d'élevage ne semble contrôlée par les changements de longueur du jour puisque les relations avec ce facteur sont, dans les climats subtropicaux, l'inverse de ce qu'elles sont dans les climats tempérés. 3. Un certain nombre de colonies commencent l'élevage des reines avant d'atteindre leur taille maximum, alors que d'autres ne le commencent pas avant de l'avoir atteint. On ne peut pas assurer que l'élevage des reines commence quand la proportion de couvain tombe en dessous d'un niveau critique. 4. Bien que l'époque à laquelle se produit l'essaimage semble déterminée par l'action directe de facteurs de l'environnement, on ne peut exclure la possibilité d'une influence partielle par un cycle de changements physiologiques à l'intérieur des colonies.
    Notes: Summary 1. Actual swarming is more frequent early than late in the summer, but its distribution probably does not truly represent the seasonal fluctuation in the intensity of the factors which induce colonies to swarm. The incidence of swarm preparations in colonies which do not actually swarm, and of empty queen cell cups in colonies which do not prepare to swarm, shows a later maximum and one which, on the average, coincides well with the maximum availability of nectar and pollen in the field. 2. The final seasonal decline in brood rearing in colonies occurs at about the same time as the diminution in the tendency to swarm and in the availability of forage. In the colonies observed brood rearing did not decline permanently before this period except in some of those in which queen rearing occurred. Generally this decline occurred only after queen rearing had begun; thus it might have been a consequence of queen rearing but, in most cases, could not have been a cause of it. More colonies started to rear queens when their brood was increasing than did so when it was decreasing. The time of breeding does not seem to be controlled by changes in the length of day since the relationship of this factor to breeding in sub-tropical climates is the opposite of that which prevails in temperate climates. 3. A number of colonies began queen rearing before they reached their maximum size while others did not do so even after they had reached their maxima. There was no evidence that queen rearing began when the ratio of brood to bees fell below some critical level. 4. Although the time at which swarming occurs seems to be largely determined by the direct action of environmental factors the possibility cannot be excluded that it is influenced to some extent by a cycle of physiological changes within the colonies.

    Notes: Summary We have carried out a randomized, double-blind trial to investigate the relationship between the dose and plasma concentration of metoclopramide and its anti-emetic efficacy and adverse effects in patients receiving cancer chemotherapy. Seventeen patients received four different infusion regimens of high-dose metoclopramide in random order with four consecutive courses of chemotherapy, to achieve an approximately eight-fold range in plasma metoclopramide concentrations. In patients receiving cisplatin the incidence of vomiting decreased with increasing metoclopramide dose, but the overall efficacy was poor. There was no relationship between anti-emetic efficacy and either dose or plasma concentration of metoclopramide in patients receiving cyclophospamide and doxorubicin. The adverse effects of high-dose metoclopramide included diarrhoea, which increased in incidence with increasing metoclopramide dose, and sedation and extrapyramidal reactions, which were not related to dose or plasma concentration. Although anti-emetic efficacy increases with increasing metoclopramide dose in patients receiving cisplatin, high-dose metoclopramide alone does not adequately control cisplatin-induced nausea and vomiting.

    Notes: 137 internal jugular vein cannulae from 113 patients undergoing open heart surgery were cultured using standard broth culture and a semiquantitative culture technique. 60 of the cannulae were placed using an aseptic technique and 77 using a standard non sterile technique. Significant contamination was found in 18.3% of the cannulae in the aseptic group and 15.6% in the standard group. The contaminating organism was Staphylococcus epidermidis in 87.1% of cases. No advantage in using an aseptic technique of cannula insertion was demonstrated. It was concluded that the major source of contamination was elsewhere.

    Notes: One-hundred-and-four children were skin-tested with four peanut-allergen preparations, a commercial extract, extracts of raw and roast peanuts prepared by NH4HCO3 extraction, and a wheatgerm lectin-reactive glycoprotein obtained by affinity chromatography. The presence of symptoms after ingestion of peanut or peanut products was also recorded. The roast allergen extract provided the greatest specificity with eight symptomatic children having a positive skin test and only one positive skin-test reaction in an asymptomatic child in the group of 104 children tested. Despite differences in the incidence of skin-test reactions there was a strong correlation between raw, roast and commercial RAST suggesting common allergens were being identified by circulating IgE. Clinical sensitivity was observed particularly in younger children with 75% of the children being under 4 years of age. A positive roast skin test or a RAST test adds confirmation to the clinical history of allergic reactions to peanuts.

    Notes: This report describes the design and operation of a diagnostic instrument used for light balance measurements in inertial fusion experiments. The instrument is a light-integrating cylinder that uses the integrating principles of the Ulbricht sphere, but which was designed to operate in a reflective illumination environment. The cylinder has been used to make measurements with both high-absorption disk targets and low-absorption foil targets, illuminated with 20–80 J of green (527-nm) light. We have also modeled the cylinder to determine its theoretical integrating performance under a variety of operating conditions. Initial sensitivity was measured at 0.4 V/J and degraded over target shot number to about 0.25 V/J. The instrument has a measurement accuracy of 10% for scattered light and an absorption measurement accuracy of 10% for strongly absorbing targets, and 30%–70% for weakly absorbing targets.

    Notes: An electron trap of 0.3 eV depth was characterized in hydrothermally grown, single-crystal zinc oxide using deep-level transient spectroscopy. Specimens were fabricated with Ag Schottky contacts on (0001) surfaces. The capture cross section was determined to be 2.6×10−14 cm2. The defect is a native donor and is attributed to a singly ionized oxygen vacancy V•O.

    Notes: Administration of cyclophosphamide to Sprague-Dawley rats 2 days before immunization with ovalbumin in complete Freund's adjuvant resulted in a striking blood, bone marrow. and tissue eosinophilia. The number of circulating eosinophils reached a maximum (50-fold increase above normal) 2 weeks after immunization, and eosinophils were also prominent in bone marrow, lymph nodes (paracortical areas), spleen (while and red pulp), and liver. The eosinophilia could be inhibited by daily oral administration of cyclosporin A (CsA), although its effect was dependent both on the duration of treatment and on the dosage of CsA. A similar, inhibitory action of CsA was demonstrated with respect to methotrexate-induced eosinophilia. This experimental model may prove useful in the study of factors regulating eosinophil production and in examining the prospective value of CsA in the treatment of conditions where eosinophils play a central role.
