    Notes: While considerable attention has been drawn to “reproduction” theories of education, little empirical research has been conducted within this framework. This paper uses the reproduction perspective to examine how various mechanisms of the American educational structure contribute to the maintenance of the mental-manual division of labor within class structure. Using a national, longitudinal sample of high school seniors, we look at the reproduction effects of public versus private schooling, the composition of school communities and curriculum tracking. We find that reproduction results from the schooling experiences of a majority of students and that tracking is the most important mechanism in this process. However, nonreproduction is apparent as well which points to some issues that reproduction theories must address to provide viable explanations of the role of education in society.

    Description / Table of Contents: Zusammenfassung Bei 10 Patienten wurde die arterielle und venöse Hämodynamik 69 bis 175 Tage nach Unterschenkelfraktur mit einer venenverschlußplethysmographischen Methode überprüft. 90,1±16,7 bzw. 120,3±16,5 Tage nach der Fraktur war die Durchblutung der erkrankten Seite im Bereich des Unterschenkels um +4,27±1,93 (p〈0,005) (+197%) bzw. +3,94±1,45 (p〈0,001) ml/100 ml Gewebe/min und im Bereich des Fußes um +0,54±0,68 (p〉0,05) (+76%) bzw. +3,39±1,24 (p〈0,001) (+424%) ml/100 ml Gewebe/min gesteigert (Vergleich mit kontralateraler Seite). Zu denselben Meßzeitpunkten war die druckabhängige Venenkapazität des erkrankten Unterschenkels um −1,32±0,61 (p〈0,005) (−38%) bzw. −0,98±1,49 (p〉0,05) (−32%) ml/100 ml Gewebe vermindert (Vergleich mit der kontralateralen Seite).
    Notes: Summary In 10 patients arterial and venous hemodynamics of the leg have been examined 69 to 175 days after fracture of the tibia using venous occlusive plethysmography. 90.1±16.7 and 120.3±16.5 days after the fracture, respectively, the bloodflow of the injured calf was increased by +4.27±1.93 (p〈0.005) (+197%) and +3.94±1.45 (p〈0.001) ml/100 ml tissue/min, respectively, whereas the bloodflow at the foot was increased by +0.54±0.68 (p〉0.05) (+76%) and by +3.39±1.24 (p〈0.001) (+424%) ml/100 ml tissue/min, respectively (as compared with the contralateral side). At the same time the venous capacity of the calf was decreased by −1.32±0.61 (p〈0.005) (−38%) and by −0.98±1.49 (p〉0.05) (−32%) ml/100 ml tissue, respectively (as compared with the contralateral side).

    Description / Table of Contents: Zusammenfassung Mit den vorgefertigten Gipsbinden Cellona®, Gypsona® und Platrix® wurden genormte Probekörper hergestellt und nach festgesetzten Trocknungszeiten Biegeund Scheiteldruckversuche durchgeführt. Nach 90 min steigt die Festigkeit deutlich an und erreicht nach 120 min einen Endwert. Die Werte sind für alle drei Gipsverbände etwa gleich.
    Notes: Summary With the prepared plasterbandages Cellona®, Gypsona® and Platrix® standardized test models were mouldet and after fixed drying times bending stresses and peak stress loadings were measured. After 90 min there was a marked increase in firmness and after 120 min the endresult was reached. The result of all three plasters bandages was similar.

    Notes: Zusammenfassung Hämsynthetase (HS)-Aktivität zirkulierender Retikulozyten und Erythrozyten von Normalspendern und Patienten mit Thalassämie wurde in vitro bestimmt. HS war normal oder erhöht bei Thalassämie. Jugendliche, über das Stadium des Retikulozyten hinaus gereifte Erythrozyten enthalten wahrscheinlich noch einen signifikanten Anteil der im peripheren Blut messbaren HS-Aktivität.

    Notes: Summary 1. In the guinea pig heart-lung-preparation (HLP) anaphylactic bronchospasm was not greatly affected by mepyramine (2–40 μg/ml blood), adrenaline (0.1 and 1 μg/ml), noradrenaline (0.1 μg/ml) or papaverine (100 μg/ml) but was completely abolished by combining mepyramine with the lower dose of adrenaline. A partial antagonism was achieved by the combined action of mepyramine and papaverine which became complete when adrenaline was added. 2. Bronchospasm due to histamine was completely prevented by mepyramine, but only partially antagonized by both adrenaline doses used. 3. The increase of pulmonary vascular resistance in anaphylaxis was not inhibited by the highest tolerated amounts of mepyramine or papaverine, no matter whether the drugs were given alone or in combination. Adrenaline, in contrast to noradrenaline, was partially effective at the lower dose (0.1 μg/ml). The higher concentration did not act more strongly. It became fully effective when mepyramine was added either alone or combined with papaverine. 4. The increase of pulmonary vascular resistance induced by histamine was strongly and significantly antagonized by mepyramine alone as well as by the lower concentration of adrenaline (0.1 μg/ml). Noradrenaline had no significant effect in either amount given (0.1 and 1 μg/ml). 5. Antigen increased heart rate in sensitized HLPs, probably due to histamine release. This effect was resistant to mepyramine. 6. The present findings are discussed a) with respect to the refractoriness of the anaphylactic bronchospasm to mepyramine, an effect displayed in isolated lung preparations but not in intact animals. b) with respect to the mechanism of the so-called protracted shock which is mainly due to heart failure.
