Commissioning of heating neutral beams for COMPASS-D tokamak.

Two neutral beam injectors have been developed for plasma heating on COMPASS-D tokamak (Institute of Plasma Physics, Prague). The 4-electrodes multihole ion-optical system with beam focusing was chosen to provide the low divergence 300 kW power in both deuterium and hydrogen atoms. The accelerating voltage is 40 kV at extracted ion current up to 15 A.

[Pharmacologic analysis of the role of catecholamines in the mechanism of alcoholic affection of the heart].

The authors studied the effect of 6-oxidopamine and rausedyl on the manifestation of cardiac disorders in rats given 3-5 g/kg ethanol by way of the stomach at 12-hour intervals for 5.5 days. 6-oxidopamine was injected intraperitoneally in a dose of 50 mg/kg 24 hours before the beginning of alcoholization and one hour after the first administration of ethanol.

[Determination of the leading factors in the pathogenesis of an alcoholic lesion of the heart].

Male rats were given per os 25% ethanol solution twice a day at 9.00 and 21.00 for 5.

Morphofunctional examination of the heart in rats with the alcohol withdrawal syndrome.

Using histochemical methods, light and electron microscopy, authors examined rat heart 2-6 hours, 1, 3, and 7 days after discontinuation of forced intoxication with alcohol. At the same time, they assessed the contractile function and creatine phosphokinase (CPK) activity in the isolated perfused heart, and the development of animal destruction. Ethanol withdrawal was followed by escalation of vascular disorders in the heart, dystrophic changes in the subcellular structures, considerable polymorphism in enzyme distribution and activity, and formation of foci containing disintegrating myocytes with contractures.
