[Electroimpulse therapy of auricular fibrillation].

Data derived from clinical, electro- and polycardiographic observations of 68 patients subjected to electric stimulation therapy are presented. The evaluation of late results of the treatment showed that clinical factors such as the patients' age, the nature of the affection, the degree of cardiac insufficiency, the standing of auricular fibrillation are not decisive in determining indications and contraindication for electric stimulation therapy. A considerable worsening of the cardiac dynamics with developing fibrillation arrhythmia, especially in patients suffering from cardiosclerosis, and a distinct improvement of the polycardiographic indices after defibrillation point to the need of attempting, whenever this is possible, to bar the auricular fibrillation.

Effects of space flight factors on Drosophila.

Drosophila melanogaster flies of strain D-32 were exposed aboard the Soyuz 10 spaceship. An insert with a nutritional medium and insects was placed in a small on-board thermostat (Biotherm II) providing a constant temperature (24 degrees C +/- 1 degree) for Drosophila development. The frequency of dominant lethals was determined in the females.
