In the second sequence, the mice also received an intraperitoneal injection of 0.one mg/g bw urethane in 0.nine% saline; the third team also received an intraperitoneal injection of 1 mg/g bw urethane. The urethane injections got just one week following initiation of saccharin administration. The incidences and figures of adenomas for every lung ended up identified; a few lungs from Each individual team of mice have been examined microscopically to verify that the adenomas were being being counted.
