Ingested mutagens from opium and tobacco pyrolysis products and cancer of the oesophagus.
摘要：
Substances which are commonly sucked or chewed in two areas where the incidence of œsophageal cancer is high, the Transkei and north-east Iran, were tested in bacterial mutagenicity assays. Pyrolysed substances, opium dross in north-east Iran and tobacco pipe residues in the Transkei, displayed mutagenic activity in Salmonella typhimuriumstrains TA98 and TA100 in the presence of rat liver microsomes.
