To further our understanding of the mechanism of CS cytoprotection , we examined in rats and mice the protective abilities of CS and the non - hydrolyzable ether form of CS , gamma - cholesteryloxybutyric acid , tris salt ( CSE ) against acetaminophen - , adriamycin - , carbon tetrachloride - , chloroform - and galactosamine - induced toxicity .
