Ein Beitrag über die Art der Wirkung einiger Antituberkulotika

Summary The direct effect of any antituberculotics on pancreatic lipase was studied by the modified method ofWillstätter. The antituberculotics were found to activate the pancreatic lipase in the presence of Ca⁺⁺. Any cations, especially copper, decreases the lipase activity. Increasing antituberculotics concentration is accompanied by an increasing effect on the lipolytic action of lipase.     

Ähnlichkeit und Unterschied Leukozytenemigrationsfördernder Wirkung gram-positiver und gram-negativer Bakterien

Summary Live gram-positive and gram-negative bacteria cause circular and chemotactic eccentric promotion of leucocyte emigration in a similar manner. In the case of gramnegative bacteria this effect corresponds to that of their polysaccharides, whereas in the case of gram-positive bacteria the polysaccharides are inactive.Thus, although gram-positive and gram-negative bacteria both have a similar effect on leucocyte emigration, the underlying mechanism of action is different.     

Geschwindigkeit der selektiven Akkumulation von Mercurascan-203 im geschädigten Muskel und im ischämischen Myokard

Summary The authors demonstrate that a hydroxy derivative of fluorescein — Mercurascan 203 — very rapidly and selectively accumulates in the injured muscle and in the ischaemic myocardium and is cleared rapidly from the blood and other tissues. In vivo, scanning is positive soon after Mercurascan-203 administration.     

The effect of pretreatment with rat placental homogenate on subsequent pregnancy in the rat

Résumé L'effet d'un traitement immunologique sur la grossesse du rat a été étudié. Les animaux du groupe expérimental ont reçu 8 injections d'homogénat placentaire à raison de deux par mois, puis ont été accouplés. Après 21 jours de grossesse il y avait moins de fétus nés vivants que dans le groupe témoins non-traité; le poids des fétus en vie était en général normal mais on a noté une augmentation significative de la masse placentaire par rapport au groupe témoin.
