A course of silicic sapropel applications compared to calcareous sapropel induced a reversible fall of total lipid concentration in blood serum of intact rats. Sapropels of different kinds and of the same kind but obtained from different depths of the same deposit varied by their ability to correct hepatic function in rats with toxic hepatitis. The highest benefit was registered in application of carbonate sapropels taken from the depth of 1.5-2.5 m.
New medicinal plant preparations of polyphenol nature, representing the derivatives of bioflavonoids (piflamin) and ellagotannins (altan and ellagic acid) were experimentally studied. The drugs exhibited antioxidant properties, which were manifested by inhibition of a pathological lipid peroxidation, restoration of the functional activity of the antioxidant system components, and stabilization of the hepatocyte membranes.
