In vitro demonstration of peroxidase activity in the fish kidney soluble supernatant and its physiological importance

Zusammenfassung In der Kopfniere des TeleostiersAnabes testudineus wurde eine besonders hohe Peroxidase-Aktivität nachgewiesen, insbesondere deren Iodid-Oxydation zu Tri-Iodid.     

Binding property of rat and Limulus C-reactive proteins (CRP) to mercury

The C-reactive proteins (CRP) from both rat and Limulus were found to bind mercury (Hg) in both in vivo and in vitro conditions. CRP has high-affinity binding sites for Hg as evidenced by the loss of free sulfhydryl groups, arrested mobility in polyacrylamide gel electrophoresis, and the consumption of CRP in the serum after Hg administration. The binding was tight as it could not be inhibited either by the addition of cysteine or EDTA. By using a direct titration method it was shown that binding of Hg to CRP was saturable at a molar ratio of Hg/CRP = 13.11. The possibility that CRP may act as a scavenger for Hg is discussed.

Stress by restraining potentiates morphine catalepsy in rats

Summary Restraint-induced stress potentiated morphine catalepsy in rats. This potentiation was partially antagonized by pharmacologic treatments decreasing central serotonin, acetylcholine, prostaglandins and by naloxone. Selective increase in central dopamine also inhibited the potentiation.Acknowledgments.

Die Reizbewegungen der Mimosoideen und ihre Hormone

Summary The irritation substances of various plants of the family of Mimosoideae are highly sensitive to oxygen, and their chemical behaviour is that of reductones. Just the same substances were also found in non-sensitive plants. Meso-inositol is perhaps one of the original compounds leading to the active substances. It became possible to explain some characteristics of the irritation-process ofMimosa pudica by regarding known properties of reductones, i.e. the irritation reaction, the restitution, the influence of sun-light and their sleeping in darkness.

Mein lieber Freund Dr.B. Banerjee hat die Fortsetzung dieser Untersuchung nicht mehr erlebt. Noch während seines Aufenthalts in Deutschland überfiel ihn die tückische Krankheit, der er kurz nach seiner Heimkehr erlag.
