Obeservation of the aging in ICR mice. (A) Appearance, body weight and telomere length. All the mice were photographed with a digital camera and their weight were measured using electrical balance. The images of mice were represented are presented as animals with average weight in each group. The total genomic DNAs were collected from the liver tissues of five to six mice per group and the length of the telomeres was analyzed twice for each mouse. (B) Ammonia concentrations in dirty bedding. The ammonia concentration was measured in dirty bedding obtained from a single ICR mouse, as described in the ‘Materials and Methods’ section. Three to five mice per group were used to prepare the dirty bedding, and the ammonia concentrations were assayed in duplicate for each bedding. The data are reported as the means ± SD. ∗p < 0.05 compared with the 2-month-old group. #p < 0.05 compared with the 6-month-old group.
