  • Abstract
  • Look Inside

 5mg of 4 NQO (4-Nitroquinoline 1-oxide) or 4 HAQO (4-Hydroxyaminoquinoline 1-oxide) dissolved in alcohol was given into the stomach of mouse by tube feeding. 5mg of drug was divided into ten doses and each dose was given once every week. Squamous epithelial cancer was originated at forestomach and adenocarcinoma was arised at glandular stomach when 4 NQO was administered. Adenocarcinoma was induced at glandular stomach but no pathological change was found at fore stomach in case of 4 HAQO. 4 HAQO has the tendency to attack glandualr stomach selectively. 4 HAQO is obtained by the reduction of 4 NQO. It is seemed as a proximate carcinogenic chemical to 4 NQO. 4 HAQO has no effect to the fore stomach lined with squamous eqithelium but attacks the glandular stomach covered by gastric glands. This drug and the origination of cancer will contribute to the advance of experimental cancer research.
