  • Title: Effect of long-term alcohol intake on the innervation of the rat myocardium.
    Author: Morvai V, Donáth T, Ungváry G.
    Journal: Acta Morphol Acad Sci Hung; 1979; 27(4):315-22. PubMed ID: 575874.
    Abstract:
    The myocardium of rats kept on DeCarli and Lieber's liquid diet containing alcohol to 36% of the total calories for 8 weeks were examined with Falck-Hillarp's method for the histologic demonstration of catecholamines. Relative fluorescence intensity of the myocardial cells and nerves was measured with the Zeiss-Fluoval microphotometer. Under the effect of alcohol, density of the noradrenergic innervation (number of visualized nerve fibres) decreases and fluorescence of myocardial cells is intensified. The increased fluorescence of myocardial cells can be eliminated with reserpine. It is assumed that chronic alcohol intake induces continuous catecholamine release from monoaminergic nerve fibres of the heart.
