Abstract
Germanium-containing organic polymers are obtained by polymerizing 3-trichlorogermylpropionic acid obtained by reacting halogermanium-phosphoric acid complexes with acrylic acid. The polymers are markedly effective in treating liver disorders.
Claims5
A method of treating an animal suffering from at least one of acute and chronic hepatitis and liver cirrhosis, which comprises;
- administering to said animal an effective amount to relieve said suffering of a polymer selected from those of the formulae:
- ##STR12## wherein A represents one of a hydrogen atom, alkyl having 1 to 3 carbon atoms, --COOH, or --COOR (wherein R is alkyl having 1 to 3 carbon atoms), B represents one of a hydrogen atom and alkyl having 1 to 3 carbon atoms;
- Z represents one of a hydroxy, alkoxy having 1 to 3 carbon atoms or alkyl having 1 to 3 carbon atoms;
- and n is an integer greater than 3, inclusive.
