[Changes in lipid content of RBC membranes in divers working on low and moderate depths.].

The study covered lipid content of RBC membranes in divers exposed to extreme hyperbaric factors at work. Findings are that prophylactic intake of biologically active additive nutrient "Kalifen" made of viburnum berries preserved physiologic characteristics of RBC and recovery of lipid components in their membranes.

[Modification of the pattern of fatty acids of erythrocytes’ membranes due to the acetone intoxication].

Results of the study of the impact of acetone intoxication on the fatty acids pattern of the general lipids of erythrocytes’ membranes in rats are presented. The inhalation exposure of acetone was carried out in the inoculation chamber with the volume of 100 liters. The chamber was designed for the type of B.

[Prevention of deteriorations of blood biochemical indices in experimental stress in rats].

Results of the research of the impact of extract from the byproducts of guelder-rose, containing a complexflavonoides (65% of dry weight), in the conditions of experimental a stress (vertical fixing of rats by a dorsal cervicalfold for 22 o’clock) are presented. The impact of a stress was shown to be followed by the gain in mass of adrenal glands by 42%. In blood serum there were noted marked hypertriglyceridemia, hypercholesterolemia, increased superoxide dismutase activity, decline in the number of reduced glutathione and anti-radical activity, the gain in lisofractions of phospholipids, decrease of phosphatidylcholine, phosphatidylethanolamine, cholesterol esters.

[Hepatorotective activity of honeysuckle fruit extract in carbon tetrachloride intoxicated rats].

We have studied the effects of the extract from the dry pomace of honeysuckle fruits Lonicera edulis Turcz. and commercial reference preparation Legalon on weight and biochemical liver indexes in rats upon carbon tetrachloride intoxication. The extract of honeysuckle fruits favored a decrease in the total lipid content, reduced specific liver weight, and facilitated restoration of the activity of serum alanine aminotransferase and liver lysosomal enzymes.

[Hepatoprotective properties of isoflavonoids from roots of Maackia amurensis on experimental carbon tetrachloride-induced hepatic damage].

Hepatoprotective properties of ethanol extract from the roots of Maackia amurensis Ruper et Maxim have been studied on the model of toxic hepatitis induced by carbon tetrachloride damage. It is established that the extract contains daidzein, 7-O-gentobiosides of isoflavonoids genistein, formononetin, pseudobabtige-nin, and 5-O-methylgenistein, and 3-O-gentobiosides of pterocarpans (6aR, 11aR)-maakiain and (6aR, 11aR)-medicarpin. The administration of extract facilitates the restoration of antioxidant protection enzymes activity and reduced glutathione level, decreases the formation of toxic peroxidation products, produces normalizing impact on liver phospholipid pattern, and improves the erythrocyte tolerance to hemolytic agents.
