Groups of twenty five male and 25 woman Charles River CD mice, 8 weeks of age, received weight loss plans made up of sodium saccharin (that contains 345 mg/kg (ppm) ortho-toluenesulfonamide) at concentrations of 0, one or 5% for up to two many years. Animals that died just before 6 months were not examined, and also the survival situations were not noted. Animals ended up killed when obvious tumours were being viewed or if they were being moribund; all survivors had been killed at two many years.
