| Outline of Final Research Achievements |
Skeletons of aging animals were collected, macro morphological changes of bones were investigated, and three dimensional images were successfully reconstructed. In Asian elephant, hippopotamus, white rhinoceros and giraffe, macro morphological anomalies in the spine, limbs, skull were detected and a fundamental theory of bone aging was constructed. In old Asian elephants, we discussed the problems of the jaw and molar tooth using three dimensional images. In medium-sized animals we observed abnormalities in the jaw and facial function, and also in birds and reptiles, we could establish the theory on the aging and morphological changes along with the physiological background. The results succeeded in greatly expanding the opportunities for collecting basic biological and pathological data on maintained animals, in addition to the direct research of aging animals. Based on these results, we also could develop the new opinion of the animal welfare towards the zoos and aquaria.
