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.     

Versuche auf dem Gebiet der Lokalanästhesie mit protrahierter Wirkung. III

Summary The addition of simple quaternary salts (as I and II) to solutions of local anaesthetics, effects a pronounced prolongation of the time of complete infiltration anaesthesia. These salts have no effect on the time of surface anaesthesia. Other pharmacological characteristics of these mixtures were also determined.

Polymethylcyclohexylamine — neue,hypotensiv wirksame substanzen

Summary A series of cyclohexylamine derivatives methylated both on nitrogen atom and in position 1, 2 and 6 of the cyclohexane ring have been prepared. Some of them showed considerable hypotensive and ganglioplegic activity. The most interesting compound is N,N,1,2,2-pentamethylcyclohexylamine (‘penhexamine’) whose activity compares favourably with mecamylamine or dimecamine.

The effect of calciferol,parathormone and calcitonin on the biochemical composition of kidney

Zusammenfassung Es wurde festgestellt, dass Calciferol die Stauung von Calcium, Phosphor und Zitronensäure in allen Teilen der Niere verursacht. Parathormon erhöht den Gehalt von Calcium und Zitronensäure in der Niere während einer Stunde. Nach Verabreichung von Calcitonin wurde Verminderung von Calcium in der Cortical-und Medullarzone beobachtet.     

The presence of smooth muscular cells in the ovary of several mammals as seen under the electron microscope

Riassunto Mediante l'impiego del microscopio elettronico viene dimostrata la reale esistenza di piccoli gruppi di cellule muscolari lisce, non in rapporto con vasi, in differenti zone dell'ovaio (stroma, corpo luteo, teca, ghiandola interstiziale) del gatto, del coniglio e del topo. Le cellule muscolari subiscono caratteristiche modificazioni in relazione al ciclo ovarico.
