Vergleichende Untersuchungen über das Amyloid und Paramyloid verschiedener Tierarten

Abstract

The histochemical attributes of amyloid and paramyloid deposits were investigated and compared, using material from cattle, dogs, mink and horses. Histochemically, there is considerable similarity between amyloid and paramyloid. Both are built from a neuraminic acid and carbohydrate-containing protein (glycoprotein), but their neuraminic acid and carbohydrate contents vary considerably in the individual varieties of amyloid. The fibrin-positive substances demonstrable in paramyloid are an indication that blood proteins are incorporated in this variety of amyloid in larger amounts than in ordinary amyloid.
