    Description / Table of Contents: Zusammenfassung 565 menschliche Seren aller Altersstufen wurden in der Verdünnung 1∶10 auf neutralisierende Antikörper gegen Adenovirus Typ 18 untersucht. Insgesamt zeigten 36% eine partielle oder vollständige neutralisierende Wirkung, wobei gewisse Schwankungen innerhalb der einzelnen Altersgruppen bestanden. Bei 131 Seren erfolgte zusätzlich die Untersuchung in der Verdünnung 1∶5. Hierbei ergaben sich wesentlich höhere Durchseuchungszahlen, die bei den 16 bis 40jährigen 84% der geprüften Seren erreichten. Daraus wird auf eine ubiquitäre Verbreitung des Virus in der Bevölkerung geschlossen. Es besteht deshalb kein Grund, den im Tierversuch schwächer Tumor-wirksamen Adenovirustypen 3 und 7 eine größere Bedeutung als mögliche Erreger menschlicher Tumoren allein wegen ihrer weiten Verbreitung in der Bevölkerung zuzuerkennen. Seren mit höheren Titern wurden nur vereinzelt gefunden. Sie erreichten maximal einen Wert von 1∶80. Hieraus wird auf eine relativ geringe Antigenität des Adenovirus Typ 18 für den Menschen geschlossen.
    Notes: Summary 565 human sera of all age groups were tested for neutralizing antibodies against adenovirus type 18 in a 1∶10 dilution. Totally in 36% a partial or complete neutralisation was seen, varieting within the age groups. 131 sera were also tested in a 1∶5 dilution, resulting a much higher proportion of sera with antibodies: 84% of the 16–40 years old persons. Therefore there is no reason to contribute the adenovirus types 3 or 7 a higher probability as causative agents of human malignancies because of their distribution in the population.

    Notes: Summary The relationship between $$P_{GO_2 }$$ , $$P_{aO_2 }$$ , local blood flow, and the activity of individual chemoreceptor fiber units of the cat's carotid body was studied during changes in the arterial oxygen partial pressure and the arterial systemic blood pressure. The following results were obtained: 1. In the normal physiological range $$P_{GO_2 }$$ follows $$P_{aO_2 }$$ almost linearly. 2. The curves of neuronal activity depending on $$P_{aO_2 }$$ or $$P_{GO_2 }$$ have different shapes. 3. Hypoxia and hyperoxia change the relationship between $$P_{aO_2 }$$ and $$P_{GO_2 }$$ as well as the relationship to the neuronal activity. When returning to normal conditions, the initial relationship is re-established. 4. Considerable changes in local flow do not change local tissue $$P_{O_2 }$$ and do not influence the neuronal activity.

    Notes: Summary A technique is described which enables the determination of local blood flow in different points of the carotid body. The blood flow measured in the middle zone of the catorid body at mean blood pressure of 120 to 130 mm Hg was about 2000 ml/100 gxmin and corresponded to the total flow values known thus far. It was found that the flow/g weight decreases from the arterial inflow towards the periphery. Under our experimental conditions no signs of autoregulation could be detected. Under special experimental conditions differnnt flow distributions were observed in the carotid body.

    Description / Table of Contents: Zusanunenfassung Nach Verlust von Muskulatur durch eine ischämische Muskelnekrose oder Trauma kann die Funktion durch Sehnentransfers wieder hergestellt werden, wenn geniigend intakte Muskulatur an einer Extremität verblieben ist. Wenn nach einem Compartmentsyndrom der Fingerbeugerloge auch die Streckmuskulatur geschädigt ist, kann heute durch eine freie Muskeltransplantation mit mikrovasculärem and -neuralem Anschluß die verfügbare Muskelsubstanz vermehrt and so die Funktion rekonstruiert werden. Es wird über 6 Transplantationen des M. gracilis auf den Unterarm zum Ersatz von Fingerbeugern and -streckern berichtet. Alle Muskeln, außer einem bei dem die Beobachtungszeit von 6 Monaten noch zu kurz ist, zeigten eine nützliche Funktion.
    Notes: Summary In cases with loss of musculature due to ischemic muscle necrosis or trauma, the function of the extremity can be reconstructed by tendon transfers if sufficient muscles are left. If one muscle group is lost and the other is also damaged, today reconstruction can be obtained by free muscle transplantation with microvascular and microneural connections. The authors report on six cases of transplantation of the gracilis muscle to the forearm to replace finger flexors or extensors. All muscles except one (in which the 6-month observation time is still too short) recovered useful function.

    Description / Table of Contents: Zusammenfassung In den arteriennahen, peripheren Bereichen des Glomus caroticum der Katze wurden arteriovenöse Verbindungen nachgewiesen, die ihrem Charakter nach unterschiedlich sind. Es ist allerdings noch nicht zu entscheiden, ob derartige Anastomosen regelmäßig vorkommen und wie sie funktionieren. Die beschriebenen Gefäßverbindungen konnten lichtmikroskopisch anhand von histologischen Serienschnitten und mit Hilfe einer weiterentwickelten Korrosionstechnik im Rasterelektronenmikroskop dargestellt werden.
    Notes: Summary In artery surrounding areas in the periphery of the carotid body of the cat we found arteriovenous anastomoses differing in respect to their character. So far, it is not yet to decide the frequency of their occurrence and their functional significance. The anastomoses were demonstrated by light microscopy of serial sections and by scanning electron microscopy with a more developed corrosion casting technique.

    Notes: Abstract We have determined effective cross-sections for resonant transfer of excitation energy from state-selected Li2 molecules to ground state Li atoms $$Li_2 A\left( {\upsilon ',J'} \right) + Li2S \to Li_2 X\left( {\upsilon '',J''} \right) + Li2P$$ with two different experimental techniques. Absolute cross-sections were derived from lifetime measurements of 114 rotational levels of theA-state subject to resonant collisions which belong to vibrational statesv′=4, 5, 6, 7 and 11 of6Li2 and7Li2. Cross-sections amount to several thousand Å2 dropping off sharply with a resonance half-width of about 16 cm−1. The resonance behaviour of the collision cross-section inferred from lifetime data could be confirmed by a double resonance technique probing the number of excited atoms with a second laser while the first laser was scanned over the Li2 X−A absorption band. Due to their high reliability our data prove a good basis for the test of theoretical models. In contrast to earlier investigations significant deviations were found to exist between the measured cross-sections and those predicted by the first-order dipole-dipole scattering theory.
