Semi-automatic external defibrillation.

Malignant arrhythmia, which is responsible for most of the out-of-hospital cardiac arrests, is ventricular fibrillation (VF). The best treatment of VF is a controlled electric shock on the chest administered in a short delay. The emergency medical technicians (EMTs) qualified to carry out this treatment in Belgium and in districts often succeed in arriving on the spot 8 minutes earlier than the people of the Service Mobile d'Urgence et de Réanimation (SMUR). The delegation of defibrillation to ambulance crew members however implies a specific teaching, training and a medical control. The Brussels experience shows that semi-automatic external defibrillation by EMT-Ds (SAED) is feasible when criteria for applying SAED in the pre-hospital phase are applicable.

Biochemical characterization of lysosomes in unfertilized eggs of Xenopus laevis.

Relations between lysosomes and yolk platelets of amphibian eggs have been suggested. This work demonstrates the presence of acid hydrolases in oocytes induced to ovulate in vitro. About 40% of the acid hydrolases are found in a sedimentable fraction, and, in accordance with the lysosomal concept, they display structural latency. Biochemical data did not indicate any association between lysosomal enzymes and yolk platelets. The mechanism of yolk resorption is discussed and it is suggested that the fusion of lysosomes and yolk platelets might be one of the mechanisms involved in yolk digestion.

A dissociation factor from embryos of Xenopus laevis.

A dissociating factor has been extracted from the ribosomal KCl wash and from the cytosol of developing embryos of Xenopus laevis. No dissociating activity could be detected in the KCl wash of ribosomes from full grown oocytes and unfertilized eggs. As in bacteria, the acitivity of the dissociation factor seems to be correlated with the rate of protein synthesis suggesting a physiological role of the dissociation factor. The possibility that the dissociation factor might be one of the components which limits the rate of protein synthesis in the oocytes is discussed.
