title: Gastric tumorigenesis by a single dose of 4-(hydroxymethyl)benzenediazonium ion of Agaricus bisporus.
abstract: 4-(Hydroxymethyl-benzenediazonium tetrafluoroborate was administered as a single intragastric instillation at 400 micrograms/g to Swiss albino mice. The treatment gave rise to glandular stomach tumours in incidences of 30% in females and 32% in males. Histopathologically, the tumours were classified as polypoid adenomas and adenocarcinomas. This diazonium ion is an ingredient of the cultivated mushroom of commerce, Agaricus bisporus. The implications are self-evident.
