[The hypolipidemic and antiatherosclerotic action of absorbable and nonabsorbable substances in the intestines].

Hypolipidemic effect of the polyphenol compound triophen possessing antihypoxic activity was demonstrated in chronic experiments on rabbits. It was also shown that a new derivative of methylxanthine, which does not penetrate the blood--brain barrier, produces a hypolipidemic and antiatherosclerotic effect. Experiments on rats, guinea pigs, and rabbits with induced hyperlipidemia revealed a hypolipidemic effect of new complex compounds which are not absorbed in the intestine--steroid glycosides digitonin and tomatonin immobilized on a polymer. These substances resemble cholesteramine in activity but are distinguished by solubility, low toxicity, and a mechanism of action which is more physiological.
