Abstract
Under the action of severe emotional painful stress the high concentration of catecholamines leads to the activation of peroxide oxidation of lipids in myocardium. Lipid peroxides affect membranes, responsible for the transport of calcium. As a result local necrobiosis and disturbances of the contractile function of the heart are developed. This emotional painful stress is regularly followed by activation of the inhibitory GABA-ergic system of the animal brains, which restricts the intensity and the time of stress syndromes. The injection of one of the metabolites of GABA-ergic system-gamoxibutirate (GOBA)-prior to stress essentially decreases the intensity of stress syndrome and prevents the stress affection of the heart muscle. Unter schweren emotionalen Streßsituationen führt der Anstieg der Katecholamine zur Aktivierung der Peroxid-Oxidation von Lipiden im Myokard. Lipidperoxide beeinflussen den Ca++-Transport durch Membranen. Infolgedessen bilden sich lokale Nekrosen und Störungen der kontraktilen Funktion des Herzens. Dieser emotionale Streß war regelmäßig von einer Aktivierung des inhibitorischen GABA-ergischen Systems im Gehirn der Tiere gefolgt, welches Intensität und Zeit des Streßsyndroms begrenzt. Die Injektion eines der Metaboliten des GABA-ergischen Systems-Gamoxibutirat (GOBA)-vor Einsetzen des Streß vermindert die Intensität des Streßsyndroms wesentlich und verhindert streßbedingte Affektionen des Herzmuskels.Keywords
