[The neurotropic and cardiotropic properties of new amino acid derivatives of isonicotinic acid]. / Neirotropnye i kardiotropnye svoistva nekotorykh novykh aminokislotnykh proizvodnykh izonikotinovoi kisloty.

Different derivatives of isonicotinic acid are used widely enough as antimicrobial and antituberculous agents. However, their neurotropic and cardiotropic effects have been studied little. The paper is concerned with investigations of these types of the activity of the new derivatives of isonicotinic acid: beta-phenyl-beta-alanine, l-proline, DL-valine, beta-alanine and DL-threonine synthesized for the first time at the Institute of Fine Organic Chemistry, Academy of Sciences of Armenia.

[Glycerinated myocardiocyte fibers in the rat myocardium as one of the models in a preclinical assessment of antianginal agents]. / Glitserinizirovannye volokna kardiomiotsitov miokarda krys kak odna iz modelei pri doklinicheskoi otsenke antianginal'nykh sredstv.

A number of cardiotropic preparations (verapamil, obsidan, pyroxan) were studied in glycerinated fibres (GF) in the experiments on rats during five twenty four hours after ligation of coronary artery. Their ability in different degree to preserve cardiomyocyte contractile fibers from the injury of ischemic processes is revealed. Positive influence of antianginal therapy was also confirmed in the experiments with coronary artery ligation on awake animals, and in experiments on the identification of actomyosin complex components.
