摘要
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 high performance liquid chromato-graphy (HPLC) and fluorescence spectrophotometry in the extract of Aspergillus-inoculated corn flour. The results suggest that the mycotoxin Sterigmatocystin may play a potential role in carcinogenesis in human.
