Two groups of male volunteers aged 20-22 years were examined. Group 1 (control) included 20 healthy male donors of the comparable age. Group 2 comprised 10 students who were asked to take 100 mg of the jellies containing the BAA Kalifen (TU 9128-152-02067936-2006), which was equivalent to 100 mg of total polyphenols a day, on fasting every day after biochemical blood studies. The serum tested before the experiment showed hypertriglyceridemia and hypercholesterolemia, suppressed hepatic etherifying function and imbalance of the fractional content of phospholipids. Exhaustion of the antioxidative system, increased lipid peroxidation, and impaired erythrocytic membrane permeability were also ascertained. Supplementation of the jellies normalized the biochemical parameters under study. From the above discussion, it follows that the jellies BIO-LAD should be used as a purposefully acting product to prevent mental and emotional stress.

[Impact of stress on hepatic lipid and carbohydrate metabolism, prevention].

An oligomer proantocyanidine complex (OPCC) isolated from the aqueous-and-alcoholic extract Kalifen and a polyphenol complex (PPC) isolated from the eleutherococcus extract were tested for their effects on carbohydrate and lipid metabolism in the rat liver under acute stress caused by hanging up of the animals by the cervical fold for 22 hours. This acute stress was accompanied by decreases in aerobic glycolysis and pentose cycle and by an increase in lipolysis. Hepatic etherifying function impaired. Lipids became predominant energy substrates. The administration of OPCC and PPC during stress promoted the preservation of carbohydrate metabolic reactions (gluconeogenesis, pentosephosphate pathway, Krebs cycle) and to the decrease of lipolysis. OPCC was shown to have stress-protective properties and to be able to diminish adrenal hypertrophy, to increase the production of oxidized equivalents (NAD+), and to enhance the activity of G-6-PDH in the rat liver. The complex is superior to the well-known antistress agent eleutherococcus, which makes it possible to regard these drugs as possible promising drugs in preventive and rehabilitative medicine.

It was found that "Eklikit" posseses membrane protective and expressed hepatoprotective activity. "Eklikit" exceeds the reference hepatorpotector, "Legalon", in its ability to increase the oxidized form of NAD+ and reduced glutatione, cholesterol ethers and reduce the time of thiopental sleep. In other cases "Eklikit" was equally effective to "Legalon".

[Regulation of the metabolism of ethyl alcohol in the body with oligomeric proanthocyanides as a preventive measure against its toxic effect]. / Reguliatsiia metabolizma étilovogo spirta v organizme oligomernyi proantotsianidinami kak sposob profilaktiki ego tokchicheskogo vozdeistviia.

The study evaluated the effects of a complex of oligomer proanthocyanidines derived from the crowns of the grapes Vitis vinifera on the oxidation of ethanol and on the activity of alcohol dehydrogenase and aldehyde dehydrogenase in the plasma of male volunteers given ethanol once, as well as in the rat liver during long-term alcohol use. Oligomer proanthocyanides were shown to be actively involved in the human and animal metabolism of ethyl alcohol in vivo. Under their action, the reductase activity was preserved, which prevented acetaldehyde from accumulating in the body since it reduces to less toxic ethanol. Oligomer proanthocyanidines from the crowns of the grape may be used to prevent a significant toxic effect of excess doses of ethyl alcohol on the body.

[Antioxidant action of oligomeric proanthocyanidins isolated from viburnum in liver lesions by carbon tetrachloride and prevention of the latter's toxicity]. / Antioksidantnoe deistvie oligomernykh proantotsianidinov, vydelennykh iz kaliny, pri porazhenii pecheni chetyrekhkhloristym uglerodom i profilaktike ego toksicheskogo éffekta.

The effect of a set of oligomeric anthocyanidins, isolated from viburnum, produced on the indices of lipid metabolism, lipid peroxidation (LPO) and on the hepatic antioxidant system in rats, who were subjected to the impact of carbon tetrachloride (CTC), was studied versus such effect exerted by preparations "Piknogenol" and "Legalon". The set of oligomeric anthocyanidins had a pronounced antitoxic and antioxidant action preventing the development of fat infiltration of the liver. The discussed preparation inhibited the processes of LPO, it normalized the level of antiradical hepatic activity and had a pronounced glutathione-saving effect, which is preconditioned by the biological activity of oligomeric anthocyanidins (traps for free radicals). The preparation can be used in prevention and treatment of toxic hepatic lesions.

[Stress-protector effect of diprim]. / Stress-protektivnoe deistvie diprima.

Diprim, a polyphenol preparation from crests of Far-Eastern grape species, influences the carbohydrate and lipid metabolism in liver of rats subjected to stress. The drug possesses antistress properties determined by the biologically active natural polyphenol derivatives. Playing the role of a buffer redox system under the stressed conditions, the polyphenol structures provide for the possibility of retaining the carbohydrate and lipid metabolism in rat liver and creating a reserve of the oxidized form of nicotinamide NAD+ coenzyme, which favors removal of the tissue hypoxia. The antioxidant properties of polyphenols from diprim preserve the phospholipid spectrum of the plasmic membranes of hepatocytes.

[Effects of a plant preparation Korrda-K on metabolic reactions in the liver of rats exposed to acetone]. / Vliianie rastitel'nogo preparata Korrda-K na metabolicheskie reaktsii v pecheni krys pri intoksikatsii atsetonom.

The paper deals with the study of the preventive effect of the plant drug Korrda-K on lipid and carbohydrate metabolism in the liver of the rat exposed to acetone inhalation. The agent was found to have hepatic and membranous protective effects. On exposure to acetone, Korrda-K promotes the normalization of blood glucose levels and other biochemical parameters. The magnitude of changes in the composition of lipids and fatty acids suggests that the preventive use of the agent favours the preservation of the membrane structure of hepatocytes changed by acetone.
