The effect of simvastatin administered for 10 days on coenzyme Q and antioxidant/oxidant balance in a rat model of diabetes mellitus and hypercholesterolaemia was studied. In the diabetic-hypercholesterolaemic rats the signs of oxidative stress-decreased alpha-tocopherol/cholesterol in the plasma (p < 0.01) and alpha-tocopherol in liver (p < 0.001) together(More)
Butyrylcholinesterase (BuChE) occurs in a multiple molecular forms whose catalytic activity depends on tissue distribution and species. The hypothesis led us to the study of BuChE catalytic properties focused on the inter-tissue and inter-species level with benzoylcholine and N-alkyl derivates of benzoylcholine (BCHn) as substrates. These compounds are soft(More)
Rheumatoid arthritis (RA) is a chronic inflammatory disease, leading to progressive destruction of joints and extra-articular tissues, including organs such as liver and spleen. The purpose of this study was to compare the effects of a potential immunomodulator, natural polyphenol N-feruloylserotonin (N-f-5HT), with methotrexate (MTX), the standard in RA(More)
Aloe vera is a rich source of many natural-health-promoting substances. The results of contemporary research on animal models indicate that the extracts have an antiinflammatory property. In this work the results of some in vitro experiments are shown: determination of the inhibitory effect of the Aloe vera extracts on the activity of partially purified(More)
Oxyprothepine in the medium of the microsomal fraction of the rat liver is biotransformed to the corresponding metabolites originating by oxidation of both sulfur atoms. The formation of S-oxygenation products is bound to the presence of NADPH, with a marked synergism with NADH. Induction with phenobarbital increases the formation of the individual(More)
The physiological function of butyrylcholinesterase (EC 3.1.1.8, BChE) is not clearly understood, but a role was suggested in the fat utilization process, resulting in positive correlation between plasma triglyceride (TG) levels and BChE activity. Consequently we tested the hypothesis that regular intake of betaine, a natural compound intervening in the(More)
Organic ammonium salts of N-(2-benzoyloxyethyl)-alkyldimethylammonium bromide (BCHn-1) type are formed by the homological series Ar-COO(CH2)2-N+(CH3)2CnH2a + 1.Br-, whose structure contains a biodegradably labile ester bond, on the basis of which they rank among disinfectants and antiseptics of soft character. They are preferentially biotransformed(More)
