Specific anti-antibody in transplantation

Zusammenfassung Durch ein immunologisches Dreieck-System (Hund-Kaninchen-Hund) wurde ein Anti-Antikörper bei Hunden erzeugt und seine Wirkung in vitro und in vivo demonstriert. Die Anti-Antikörper-Methode bietet neue Möglichkeiten, dem Problem der Transplantat-Abstossung und der Therapie der Krankheiten immunologischen Ursprungs näherzukommen.

Special forms of amitotic nuclear division in striated muscle and other insect tissues

Résumé On décrit quelques aspects morphologiques de l'appareil nucléaire des fibres musculaires striées des insectes. Le nom Polykaryonéma est proposé pour désigner les noyaux filamenteux géants qui par fragmentations successives produisent des chaÎnes de noyaux indépendants, placées dans le centre des fibres musculaires adultes. Ce phénomène offre un bon exemple de division nucléaire amitotique.     

Diurnal variations in cholinesterase activities in the slug,Laevicaulis alte

Summary Cyclical variations in acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) levels in foot muscle (FM) and AChE activity in central nervous system (CNS) ofLaevicaulis, during 24-h-day, were maximal at 04.00 h and minimal at 12.00 h. But BuChE activity was 180°C out of phase with AChE in CNS. The rhythmic trend of AChE in CNS might be due to true cholinesterase activity.Acknowledgements. The Senior Fellowship (CSIR) awarded to TPK is thankfully acknowledged.     

Cross-linked arabinogalactan: A new affinity matrix for the purification ofRicinus communis lectins

Summary Arabinogalactan has been cross-linked to give a new high capacity affinity matrix for the purification ofRicinus communis lectins. It shows a capacity which is 50 times greater than that of the conventional affinity matrices.     

Cadmium-113 FT NMR-spectra of rabbit liver metallothioneins

Summary Cadmium-113 FT NMR-spectra of rabbit liver metallothionein-I and-II gave 6 and 7 NMR-signals, respectively, at between 610 and 670 ppm downfield from aqueous Cd(ClO₄)₂ solution (0.1 M).We thank Mr M. Imanari (JEOL) for the NMR-data and Dr K. Kubota (NIES) for encouragement.
