title: Comparison of calcium accumulation between the arteries of human and monkey.
abstract: To examine whether an accumulation of elements in the arteries was affected by the way of walking, the authors investigated age-related changes of elements in the arteries of the Japanese, Thai, and Japanese monkeys. After the ordinary dissections by medical students were finished, the subclavian, axillary, brachial, radial, common iliac, external iliac, femoral, and posterior tibial arteries were resected from the subjects of the Japanese and Thai over 60 yr of age and they were also resected from the Japanese monkeys over 20 yr of age. The element content was determined by inductively coupled plasma-atomic emission spectrometry. It was found that in an comparison between the arteries of anatomically corresponding regions, the average content of Ca was eight times or four times higher in the arteries of the lower limb than in the arteries of the upper limb in the Japanese or Thai over 60 yr of age, respectively. In the Japanese monkeys over 20 yr of age, the average content of Ca was 1.2 times higher in the arteries of the lower limb than in the arteries of the upper limb. The result suggests that an accumulation of Ca in the arteries of the lower limb with aging is affected by the way of walking.
