[Neurophysiological analysis of the effects of antihypoxic versus psychotropic agents].

The Fourie EEG spectral analysis of thr sensomotor cortex and dorsal hypocampus in freely moving rats could reveal the common pharmacological EEG effects of different antihypoxic agents (gutimin, amtizole, emoxipine, and 3-OPK). All the agents decreased the total EEG power (they all reduced the absolute power in all frequency bands) and simultaneously enhanced (2 relative power. The former suggests that there was a decrease in the energetic level of bioelectric fluctuations, which may indicate that the brain reduces its energetic functioning level.

[The effect of ecdysterone on experimental arrhythmias and changes in the hemodynamics and myocardial contractility induced by coronary artery occlusion].

In acute animal experiments it was shown that phytoecdizon ecdisteron (ecdisten) in some animals eliminates arrhythmia caused by the ligation of the descending branch of the left coronary artery and prevents the development of fibrillation and also corrects the hemodynamic parameters and the structure of the heart contractility, prevents the development of arrhythmias induced by aconitine and calcium chloride. The mechanism of the antiarrhythmic action is related to the membrane stabilizing effect and the improvement of the hemodynamic parameters and the heart contractility is due to an increase of the adaptative possibilities of the myocardium.
