STRUCTURAL SIMILARITIES BETWEEN A PIGMENT FOUND IN THE INTESTINAL LYMPH NODES OF CATTLE AND A PIGMENT FOUND IN THE HUMAN JEJUNAL MUCOSA (ANALOGIE STRUTTURALI TRA UN PIGMENTO IN LINFONODI INTESTINALI DI BOVINI ED UN PIGMENTO NELLA MUCOSA DIGIUNALE UMANA),
Abstract
A granular, brownish-black, Schmorl-positive, PASnegative pigment, giving a negative reaction to stains for iron, not discolourable by 130 vol. H2O2, etc., was found in the medullary layers of mesenteric lymph nodes from young cattle fed with broad beans (Vicia faba). The similarities between the chemical properties of this pigment and those of a pigment previously observed by Astaldi and Strosselli in the human jejunal mucosa are stressed. These similarities suggest that it may possibly be the same pigment. The hypothesis is suggested that in both instances the pigment is a favic pigment, introduced with the diet. (Author)
