Administration of formaldehyde at doses of 11 to 110 rag/kg body weight by gastric intubation to male F344 rats induced up to 100‐fold increase in ornithine decarboxylase activity with a maximum after 16 hr and up to 49‐fold increase in DNA synthesis with a maximum after 16 hr in the pyloric mucosa of the stomach. These results suggest that formaldehyde has tumor‐promoting activity in carcinogenesis in the glandular stomach.
