Annot For finding-out of a role of separate groups of polyphenols in realization hepatoprotective properties of maksar we investigate activity of polyphenolic complexes (PPC) from duramen and cellular culture of maakia amur. Experiments are carried out on 40 not purebred white rats with an experimental СCl4-hepatites. Therapeutic efficiency of researched objects estimated on their influence on survival rate of animals, morphological and biochemical parameters of a liver and wheys of blood. In rat's CCl4-hepatitis PPC from duramen and cellular culture of maakia amur reduce the acute toxity of tetrachloromethane, decrease the necrosis of hepatocytes and cellural infiltration of liver's parenchyma, prevent from development of fatty and protein dystrophy of a liver, normalize the activity of amino transferase, ƒ-glutamyltransferase in blood, the concentration of proteins and lipids, stimulate conjugation of bilirubin. The therapeutic effect of PPC of cellular culture is more evident. The hepatoprotective action is caused by a presence of isoflavonoids daidzein, retuzin, genistein, afromozin, formononetin, orobol, tektorigenin, maakiain and medicarpin. PPC from a culture of cells doesn't influence on a level of cholesterol in blood, that apparently is caused by an absence of mono- and dimeric stilbenes in its structure.

Comparative evaluation of hepatoprotective properties of polyphenolic fraction from wood (Maksar) and a polyphenolic complex of cell culture of Maakia amurensis.Therapeutic efficacy of the objects was assessed by their effect on the MR tomographic performance of the liver of rats with experimental СCl4-hepatitis. Hepatoprotective activity of polyphenol complex cell culture Maakia amurensis is not inferior to the original effect of the drug Maksar.

Objective. Investigation of hypolipidemic effect of sesquiterpene γ-lactone Arglabin in hepatoma tissue culture (HTC).Materials and methods. In this study we’ve evaluated the effect of sesquiterpene γ-lactone Arglabin and gemfibrozil (reference drug) on the lipid content in the hepatoma tissue culture (HTC) which were incubated with a fat emulsion “Lipofundin” by fluorescent method with vital dye Nile Red. The cell viability was investigated using the MTT-test and staining by Trypan blue.Results. Cultivation of cell cultures of rat’s hepatoma cell line HTC with Arglabin and gemfibrozil in concentrations from 10 to 50 μmol and from 0.25 to 0.5 mmol, respectively, had no cytotoxic effect. HTC cell viability did not change compared with the corresponding rate in the control culture. Experimental hyperlipidemia in hepatoma culture was induced by the addition in the incubation medium of fat emulsion “Lipofundin” in a final concentration of 0.05 %. The fluorescence intensity of Nile Red in the cells was increased 4-fold (p < 0.05), which indicates a significant accumulation of lipids in the cytosol of cells. In these steady-state Arglabin and gemfibrozil at concentrations 75–100 μM and 0.25–1.0 mM, respectively, reduced the content of lipid in cells. Conclusion. In the model of hyperlipidemia induced by lipofundin, sesquiterpene γ-lactone Arglabin prevents the accumulation of lipids in the HTC cell line, as evidenced by a decrease in Nile Red fluorescence. However hypolipidemic effect of Arglabin is associated with cytotoxic effects, which is typical for anticancer drugs.
