A few teams of controls received distilled h2o. In the primary series, no treatment in addition to saccharin or h2o was administered. Inside of a next collection, the mice also gained an intraperitoneal injection of 0.1 mg/g bw urethane in 0.nine% saline; the 3rd team also obtained an intraperitoneal injection of one mg/g bw urethane. The urethane injections were given one 7 days just after initiation of saccharin administration. The incidences and figures of adenomas per lung were established; a few lungs from Each individual group of mice were examined microscopically to confirm which the adenomas were being remaining website counted. The animals usually survived the procedure very well, almost all of the deaths becoming due to trauma induced by gavage.
