title: [Blood concentrations and secretory capacity of calcitonin in blood in osteoporosis].
abstract: The deficiency of calcitonin, CT, which has an inhibitory effect of bone resorption might be related to the pathogenesis of osteoporosis. Therefore, in this paper, in regard to the sex difference, the changes with aging, and the comparison with patients with osteoporosis and normal controls, the basal value and the secretion capacity of CT concentrations in the blood, and the metabolic clearance rate, MCR, and the production rate, PR, of CT have been reviewed.
