Study of the N-(2,3,4-Trimethoxybenzyl)-N-{2-[(2,3,4-Trimethoxybenzyl)Amine]Ethyl}-1,2-Ethandiamine Compound Effect on the Physical Performance of Animals.

We studied the effect of N-(2,3,4-trimethoxybenzyl)-N-{2-[(2,3,4-trimethoxybenzyl)amino]ethyl}-1,2-ethanediamine (compound ALM-802) on the physical performance of mice after acute fatigue. The animals' performance was assessed on a treadmill. The criterion for assessing exercise tolerance was the length of the distance passed when running on a treadmill until complete fatigue.

Correlation of the Left Ventricular Systolic Dysfunction and Ventricular Depolarization in a Post-Infarction Model of Chronic Heart Failure.

The body surface potential mapping of the heart during the period of ventricular depolarization and the inotropic function of the ventricles were studied in rats under conditions of a translational model of post-infarction chronic heart failure developed by us. We revealed a statistically significant (p<0.001) correlation between the left-ventricular ejection fraction and the values of the maximum positive and negative extrema of the cardioelectric field on the body surface of rats with post-infarction chronic heart failure caused by anterior transmural myocardial infarction.

Changes in Microcirculation in the Brain, Heart, and Liver in Female Rats with Translational Model of Alcoholic Cardiomyopathy.

We studied some features of blood and lymph microcirculation in the brain, heart, and liver of female rats with developed alcoholic cardiomyopathy. In female rats after 24-week forced consumption of 10% ethanol solution, the size and inotropic function of the heart were measured by echocardiography. Microcirculation in the brain, myocardium, and liver was assessed by laser Doppler flowmetry using LAKK-OP2 and LAZMA-D computerized laser analyzers.

To the Mechanism of the Antiarrhythmic Action of Compound ALM-802: the Role of Ryanodine Receptors.

The effect of the compound N-(2,3,4-trimethoxy)-N-{2-[(2,3,4-trimethoxybenzyl)amino]ethyl}-1,2-ethane-diamine (code ALM-802) on the amplitude of the Ca response in the cell was studied in in vitro experiments. The concentration of intracellular calcium was assessed using a Fura-2 two-wave probe. The experiments were performed on a culture of isolated rat hippocampal neurons.

Dynamics of the Cardioelectric Field on the Body Surface during Atrial Depolarization in Rats with Experimental Holiday Heart Syndrome.

In model experiments reproducing the holiday heart syndrome in rats, a discrepancy between the depolarization of the right and left atria has been revealed, which manifested by an atypical arrangement of positive and negative cardiopotentials in the cardioelectric field on the body surface during the P wave and the absence of inversion of the areas of cardioelectric potentials before the onset of P waves in lead II ECG from the limbs.
