| Popis: | A transplantable argyrophilic gastric carcinoid of Praomys ( Mastomys ) natalensis contained appreciable activities of specific histidine decarboxylase and aromatic l -amino acid decarboxylase which may relate to the inherent properties of its parent cells, probably histamine-containing argyrophil cells distributed in the gastric mucosa. Specific histidine decarboxylase free from aromatic l -amino acid decarboxylase was purified 10-fold by acid plus heat treatment and subsequent ammonium sulfate precipitation; it was not essentially different from that prepared from other mammalian sources. |
