[Excretion of catecholamines in development of the opium and alcohol abstinence syndrome and in post-abstinence period]. / Ekskretsiia katekholaminiv pid chas rozvytku opiinoho i alkohol'noho abstynentnoho syndromu ta v pisliaabstynentnomu periodi zakhvoriuvannia.

Excretion of catecholamines has been studied in patients with opium narcotic and alcoholic dependence in developmental dynamics of the opium and alcoholic abstinence syndrome and in the postabstinence period. It has been revealed that 8-10 h after cessation of the psychoactive substances (the preabstinence period) the level of excretion of adrenaline [A], dioxyphenylalanine [DOPA], dopamine [DA] and, to the greatest extent, of noradrenaline [NA] especially in patients with alcoholic dependence decreases in comparison with the control variant. As compared to the control variant the acute form of abstinence syndrome (1-3 days after cessation of the psychoactive substances is characterized by the higher level of the A and DA excretion and the lower level of the NA excretion (especially in patients with opium narcotic dependence). As compared to the preabstinence period under conditions of the acute abstinence syndrome there is an essential increase in the level of the A, NA, DOPA and DA excretion. As compared to the control variant the postabstinence period (10-20 days after cessation) is characterized by the lower level of the NA excretion, especially in patients with alcoholic dependence, and of DOPA. The level of DA decreases in patients with alcoholic dependence. As compared to the acute abstienence syndrome the postabstinence period differs by the lower level of the A, NA (especially in patients with alcoholic dependence), DOPA (only inpatients with alcoholic dependence) and of DA excretion.

[Effect of glutaminic acid on the activity of the sympatho-adrenal system and the concentration of calcium in urine under conditions of development of the alcohol abstinence syndrome]. / Vplyv hlutaminovoï kysloty na aktyvnist' sympatyko-adrenalovoï systemy i vmist kal'tsiiu v sechi dynamitsi formuvannia alkohol'noho abstynentnoho syndromu.

The paper deals with the influence of glutaminic acid on the functional activity of the sympatho-adrenal system and the concentration of calcium in urine under conditions of the alcoholic abstinence syndrome development. Changes in the functional activity of sympatho-adrenal system and in the concentration of calcium in the process of the abstinence syndrome development are shown to be of the phase character. It is established that in the period of the developed abstinence syndrome glutaminic acid produces a normalizing action on the excretion of adrenaline and dopamine and also facilitates a decrease in the level of calcium in urine.

[The effect of medikhronal on the psychophysiological and metabolic processes in alcoholism]. / Vplyv medykhronalu na psykhofiziolohichni ta metabolichni protsesy pry alkoholizmi.

Pathopsychological examination, biochemical analysis of blood and urine as well as electroencephalogram (REG) were made in patients of the second (II) stage of alcoholism. The state of higher nervous activity (HNA) before and after treatment with antialcoholic drug medichronal was also analyzed. It has been shown that the course of treatment with medichronal applied to patients with alcoholism results in the removal of the inclination to alcohol, to improvement of functional state of the central nervous system, as well as ethanol (E), acetaldehyde (AcA) and catecholamines (CA) exchange, the disturbances in their metabolism (and first of all AcA) apparently being the basis of pathogenetic mechanisms of alcoholism.

[The physiological and biochemical indices of the disposition of rats to alcohol use]. / Deiaki fiziolohichni ta biokhimichni pokaznyky skhyl'nosti shchuriv do vzhyvannia alkoholiu.

Activity of aldehide dehydrogenase (ALDH), alcohol dehydrogenase (ADH) in cytoplasmic fractions of brain structures (hypothalamus, midbrain, new cortex) and in blood serum as well as the content of noradreneline (NA) and dofamin (DA) in the mentioned structures and blood of rats preferring ethanol (PE) and rejecting ethanol (RE) has been investigated. ALDH isoforms have been revealed in rats preferring ethanol (PE) and these rejecting it (RE). The activity of the revealed forms of ALDH is higher in PE rats that in RE rats. PE and RE rats do not differ from one another as to ADH activity. It is shown that the NA content is decreased in PE rats and the DA level is increased in a number of brain structures and in blood as compared to RE rats.

[Brain lipid composition of the rat with experimental morphine dependence]. / Zminy lipdnoho skladu mozku tvaryn z eksperymental'noiu morfinnoiu zalezhnistiu.

The brain phospholipid content was studied in rats with morphine physical dependence. It was found that level of total lipids, total phospholipids and cholesterol was diminished. The significant decrease of absolute amounts of phosphotidyl serine, phosphotidyl inositol, sphingomyelin and phosphatidyl choline was shown. At the same time the percent relation of individual phospholipids did not change. As the exclusion, the quantity of phosphatidyl ethanolamine plasmalogen lowered in rats with morphine dependence. The percent content of fatty acids 16:0, 18:1 omega 9, 20:1 omega 11, 20:4 omega 6 and 22:5 omega 3 was found to be reduced. At the same time the percent amount of i18:0 and 20:0 was shown to increase. As a result the unsaturation index dramatically diminished. It was also shown that under morphine physical dependence the acyl residues of phosphatidyl choline and phosphatidyl ethanolamine changed. It was concluded that lipids play significant role in the development of morphine physical dependence.

The Department of Functional Biochemistry was organized at the Institute of Biochemistry of the National Academy of Sciences of Ukraine in 1990. Since that time the collaborators of the Department develop the aldehyde hypothesis of pathogenesis of chronic alcoholism and new high effective methods of its treatment; they have found certain adaptation mechanisms arising in the organism under stress states and pathogenetic mechanisms of formation and development of the radiation encephalopathy in victims of the accident at the Chernobyl NPP. The department researchers have published 92 works.
