Molisch-positive Mucopolysaccharides of Gastric Cancers as Compared with the Corresponding Components of Gastric Mucosae

Third Report On MPS (Mucopolysaccharide) II

Abstract

1. MPSs II, cancerous and non-cancerous, in the First Report were examined physically, chemically and biologically.
2. They proved homogeneous electrophoretically and absorbed no ultraviolet light near 260 mμ.
3. They are made up of same components.
4. However, glucosamine/galactosamine ratio and contents of glucose, of sialic acid and of L-fucose vary from substance to substance.
5. Their optical rotations resemble each other.
6. They don't possess group activity within ABO classification. They are also devoid of KIK- and toxohormone-activity.
