The saccharin preparations had been created up freshly each week in distilled h2o and administered in a dose of one g/kg bw day-to-day by gavage on five days every week for a total of 17 months. 3 groups of controls acquired distilled drinking water. In the first series, no treatment besides saccharin or drinking water was administered. In the next collection, the mice also received an intraperitoneal injection of 0.one mg/g bw urethane in 0.9% saline; the 3rd team also acquired an intraperitoneal injection of 1 mg/g bw urethane. The urethane injections were given 1 week following initiation of saccharin administration. The incidences and numbers of adenomas for each lung had been determined; several lungs from Every single group of mice have been examined microscopically to verify the adenomas were being being counted. The animals normally survived the remedy nicely, the vast majority of deaths remaining resulting from trauma induced by gavage. The animals subjected to saccharin preparations obtained fairly considerably less bodyweight compared to Handle animals throughout the program of this experiment, but their pounds gain was substantial.
