Twenty male and female monkeys (6 African inexperienced, 7 rhesus, six cynomolgus and one particular rhesus/cynomolgus hybrid) have been subjected to 25 mg/kg bw sodium saccharin inside the diet program on 5 days a week from 24 h soon after start around 24 several years of age. Eight monkeys died amongst 103 and 282 months of age, and the remainder had been killed at involving 207 and 283 months of age.
