Animals that died in advance of 6 months weren't examined, and the survival times weren't noted. Animals were being killed when apparent tumours ended up observed or when they ended up moribund; all survivors were killed at two several years. All animals that survived 6 months or extended were examined grossly, and any tissues with abnormal variations had been examined histologically; Furthermore, all vital organs from no less than twelve animals in Each individual group have been examined histologically.
