[Disturbances in catecholamine metabolism during formation and development of chronic alcoholism].

Abstract

There has been carried out an investigation dealing with catecholamines metabolism in the patients suffering from alcoholism in the first, second and third stage at the short-term remission. The first developed alcoholism stage was determined as a typical one for increasing the excretion with urine of DOPA, dopamine (DA), noradrenaline (NA) and adrenaline (A), as well as the blood levels of DA, NA and A. DA/NA rate evidences about an increased synthesis of NA with DA. The marked second alcoholism stage is characterized by an acute decrease of excreting with urine and blood levels of NA. Alongside with the latter. DA excretion with urine and its blood levels remained high. DA/NA rate indicates to the considerably low relative activity of NA with DA synthesis, both in relation to the control and to the developed first alcoholism stage. In the third alcoholism stage NA excretion with urine and its blood levels become lower relatively to the marked second stage. Simultaneously DA excretion with urine and its blood levels are lower than in the developed second stage, hower exceed the control values. DA/NA rate testifies the slight activation of NA and DA synthesis. The results obtained in the work indicate to the significant role of CA metabolism disturbances in the alcoholic dependence formation.
