[Hepatoprotectors prevent the toxic action of cyclophosphamide on the liver of rats with CCl4-induced hepatitis model].

The results of experiments on white rats with CCl4-induced hepatitis showed that the combined introduction of cyclophosphamide and hepatoprotectors of the plant origin (lochein, maksar, silimarin) leads to a decrease in acute toxicity and to less pronounced manifestations of hepatotoxicity of cyclophosphamide. Hepatoprotectors decrease the activity of aminotransferases, reduce the level of bilirubin, normalize the content of protein andpipids in the blood serum, and suppress the development of morphological disorders in the liver.

[Hepatoprotector properties of polyphenolic complexes from wood and cell culture of Maackia amurensis].

Polyphenolic complexes (PPCs) extracted from core wood and cell culture of Maackia amurensis decrease the acute toxicity of tetrachloromethane, suppress the necrosis of hepatocytes and the cellular infiltration in liver parenchyma, prevent the development of fatty and protein dystrophy in the liver, normalize the activity of aminotransferases and gamma-glutamyltransferase in the blood, restore the protein and lipid content, and stimulate the conjugation of bilirubin. The therapeutic effect was more pronounced for the PPC obtained from the cell culture. The hepatoprotector effect of the PPCs is due to the presence of isoflavonoids, including daidzein, retusin, genistein, afromosin, formononetin, orobol, tektorigenin, maakiain, and medicarpin. Ther PPC from the cell culture of Maackia amurensis does not affect the blood cholesterol level, which is probably explained by the absence of mono- and dimeric stilbenes in this cell culture.

[Hepatoprotective properties of liproxol]. / Gepatoprotektornye svoistva liproksola.

The experiments on rats with a model toxic liver damage (tetrachloromethane hepatitis) showed evidence of a high hepatoprotector activity of liproxol, representing a combination of eplir and lokhein mixed in a 1-12 ratio. Liproxol inhibits lipid peroxidation, stimulates the excretory and detoxicant functions of liver, reduces hyperfermentation, and normalized membrane phospholipid composition.

[Therapeutic effect of hepatoprotectors in experimental Reye syndrome]. / [Gepatoprotektory okazyvaiut lechebnoe deistvie pri éksperimental'nom sindrome Reie]

Maxar and legalon--hepatoprotectors containing polyphenols--exhibit a therapeutic effect with respect to the experimental Reye's syndrome induced in rats by intraperitoneal injections of 4-pentenoic acid. Maxar restores the activity of enzymes of the hepatic origin, normalizes the content of bilirubin, glucose, phenols, and malonic aldehyde in the blood serum, stimulates the production of ketone bodies and ammonia detoxication, and improves the histologic structures of liver and cortex. Legalon also decreases the structural-metabolic disorders accompanying the Reye's syndrome, but to as lower ewxtent.

[The joint use of prednisolone and phospholipid-containing hepatoprotectors in experimental chronic hepatitis]. / Sovmestnoe primenenie prednizolona i gepatoprotektorov, soderzhashchikh fosfolipidy, pri éksperimental'nom khronicheskom gepatite.

In chronic CCl4-hepatitis in rats phospholipid-containing hepatoprotectors, essentiale and eplir differ in their influence on the therapeutic effect of prednisolone; essentiale does not change the antiproliferative effect of the glucocorticoid and weakens its membrane-stabilizing effect, eplir increases these therapeutic effects of prednisolone. Besides, eplir, in distinction from essentiale, reduces lipid accumulation in the liver and hypoproteinemia which are induced by prednisolone.

Hepatoprotective drugs eplyr, essential, salsocollin, macsar and legalon in rats with chronic CCl4 hepatosis prevent fibrosis development, inflammatory infiltration of portal tracts, dystrophia and hepatocytes necrosis, reduce the content of hepatic glycoseaminoglycanes, oxyproline and different collagenic fractions in liver, weaken manifestations of cytolytic and cholestatic syndromes, improve antitoxic hepar function.
