Abstract
Abstract Processes of orally treating hypercholesteremia in mammals and birds. Ether-type anion exchangers based on polysaccharides and cross-linked polysaccharides are orally administered to hypercholesteremic mammals such as humans and animals, such as dogs; and birds, such as cockerels, in the amelioration and control of hypercholesteremic affections.
