[Sterigmatocystin induced adenocarcinoma of the lung and atypical hyperplasia of glandular stomach in mice].

Aspergillus versicolor was isolated from the gastric juice of patients with chronic stomach diseases in high-risk area of gastric cancer. Mice fed with aspergillus-inoculated corn flour developed adenocarcinoma of the lung in 15 of 35 mice (42.9%) and atypical hyperplasia of the glandular stomach in 13 of 35 mice (37.4%). Sterigmatocystin was identified by HPLC and fluorescence spectrophotometry in the extract of aspergillus-inoculated corn flour. The results suggest that the mycotoxin sterigmatocystin is a potential carcinogen in human.
