    Notes: Abstract Large quadrupole moments of 1-phonon states of sperical nuclei are shown to follow in a simple and direct way from time-dependent HF equations using the self-consistent perturbation expansion. Whereas the first order describes harmonic quadrupole oscillations, anharmonic terms arise in second order. The scattering of quasiparticles by quasi-particle pairs, which is neglected in RPA calculations, but included in this paper, leads to a second order response of the system and is shown to produce a strong enhancement of the quadrupole moments. Explicit results are obtained with a pairing-plus-quadrupole interaction and discussed within a schematic two level model.

    Description / Table of Contents: Summary 1. Female mice infected intraperitoneally with Coxsackie virus B3 (250,000 LD50 for newborn mice) before mating protected their offspring passively against a challenge-inoculation with 500 LD50 doses of the homotype virus given on the first day of life. Mice delivered close to term by caesarean section from Coxsackie virus infected mothers were highly resistant to the challenge dose of virus. Thus they had acquired their type-specific immunity in utero in consequence of maternal antibodies passed either across the placenta or by way of the yolk-sac. The milk of infected mothers had only little protective effect. The average number of newborn mice per litter was significantly smaller in the group of infected females as compared with the group of non-infected females. 2. One to 3 days before term pregnant mice were infected intraperitoneally with Coxsackie virus B3. Suckling mice nursed by these females showed paralysis and high mortality (59/77 animals), whether they were born of noninfected or infected mothers. Coxsackie virus B3 (0.5 or 2.5 millions LD50 for newborn mice) administered intraperitoneally to mice during the last 3 days of pregnancy or within 2 hours after delivery was recovered from the content of stomach and also from skelettal muscles of suckling mice nursed by these females, thus demonstrating the transmission of this virus by way of the milk. No evidence for or against transplacental passage of the virus was found. Some of the pregnant mice infected in the last days of gestation showed increased susceptibility to Coxsackie virus B3.
    Notes: Zusammenfassung 1. Am Tag der Paarung mit Coxsackievirus B3 (250.000 LD50) intraperitoneal inokulierte Weibchen vermochten ihre Nachkommen gegen eine Testinjektion von 500 LD50 Virus am ersten Lebenstag wirksam zu schützen. Die Immunität wurde, wie Versuche mit durch Hysterektomie gewonnenen Jungen zeigten, intrauterin erworben und war typspezifisch. Die Milch infizierter Weibchen wirkte allein nur schwach immunisierend. Die durchschnittliche Wurfgröße der vor der Konzeption infizierten Weibchen lag signifikant unter dem Wert für nicht infizierte Kontrolltiere. 2. Wurden trächtige Weibchen 1 bis 3 Tage vor der Geburt mit Coxsackievirus B3 infiziert, so entwickelten viele der von ihnen gesäugten Jungen Lähmungen und 59 von 77 starben innert weniger Tage. Im Mageninhalt und in der Skelettmuskulatur von Babymäusen, die von kurz vor oder bis 2 Stunden nach der Geburt infizierten Weibchen gesäugt wurden, ließ sich Coxsackievirus B3 nachweisen, wodurch die Virusübertragung durch die Milch belegt wurde. Der Allgemeinzustand einiger 1 bis 3 Tage vor Geburt infizierten Weibchen verschlechterte sich vorübergehend.

    Venentonus und Durchblutung in Hautgefäßen bei intermittierend forcierter Inspiration oder Exspiration (1970)

    Description / Table of Contents: Zusammenfassung Die Wirkungen von intermittierend forcierten In- oder Exspirationen (1500 ml alle 10 sec bei im übrigen spontaner Atmung) auf den Hautvenentonus am Unterarm, die Hautdurchblutung am Finger und den peripheren Venendruck wurden an 13 gesunden Versuchspersonen untersucht. Bei forcierten Inspirationen zeigte der Venentonus deutliche initiale Steigerungen und kehrte nur langsam in den Bereich der Vorwerte zurück. Bei forcierten Exspirationen traten dagegen schwächere Venentonussteigerungen auf, die Vorwerte wurden schneller wieder erreicht. Die Fingerdurchblutung nahm bei forcierten Inspirationen stärker als bei forcierten Exspirationen ab und kehrte annähernd gleichzeitig mit dem Venentonus in den Bereich der Ausgangswerte zurück. Der periphere Venendruck stieg bei forcierten In- und Exspirationen an und erreichte relativ schnell ein weitgehend konstant bleibendes neues Niveau. Meist lagen die Werte bei forcierten Inspirationen über denen bei forcierten Exspirationen. Als Ursache der vasomotorischen Reaktionen im Bereich der Kapazitäts- und Widerstandsgefäße der Haut werden atmungsabhängige Druck- bzw. Volumenänderungen der Lunge und des Thorax angesehen, die gleichgerichtete Effekte in beiden Gefäßtypen verursachen.
    Notes: Summary The effects of intermittent forced inspirations or expirations (1500 ml every 10 sec but otherwise spontaneous respiration) on the venous tone of skin vessels of the forearm, the skin blood flow of the finger and the peripheral venous pressure were investigated on 13 healthy subjects. With forced inspirations the venous tone at first markedly increased and then it returned slowly to its previous values. With forced expirations the venous tone showed smaller increases and reached the previous level faster. The skin blood flow of the finger decreased with forced inspirations more distinctly than with forced expirations and returned to its resting level nearly simultaneously with the venous tone. The peripheral venous pressure rose with forced inspirations or expirations and rapidly reached a new level. In most cases the values were higher with forced inspirations than with forced expirations. It is suggested that the vasomotor reactions of the capacity and resistance vessels are caused by pressure or volume changes of the lungs or of the thorax, respectively, which provoke qualitatively similar effects in both types of vessels.

    Description / Table of Contents: Samenvatting Met behulp van een mixertechniek wordt aangetoond, dat na een begieting van de wortels van jonge meloenen met benomyl (75 mg actieve stof/pot van 450 ml) de infektie doorFusarium oxysporum f. sp.melonis in kunstmatig besmette aarde heel laag blijft. In geïnfekteerde planten veroorzaakt deze behandeling een sterke vermindering van de hoeveelheidFusarium in de stengel. Wanneer de planten behandeld worden juist voor zij de eerste symptomen aantonen, wordt gewoonlijk de ontwikkeling van de parasiet gestopt zodat de planten kunnen genezen. Het produkt blijft tenminste 10 weken actief in de grond.
    Notes: Abstract It is demonstrated that benomyl, applied as a soil drench, is highly efficient in reducing the quantity of mycelium in muskmelon plants infected byFusarium oxysporum f. sp.melonis. When treated before symptoms appear, plants are generally cured. The blending technique used for assessing fungal spread in the xylem vessels is particularly convenient for studying the action of a systemic fungicide in a plant with vascular wilt.
