title: [Studies of calcium-phosphorus metabolism in thyrotoxicosis].
abstract: Fifty eight patients with thyrotoxicosis were examined as well as 9 patients with hypothyroidism and 40 healthy subjects. A tendence towards hypercalcemia and hyperphosphatemia, hypercalciuria, hyperhydroxiprolinuria, elevated alkaline phosphatase were found in hyperthyroidism. In hypothyroidism--hypocalcemia, hypocalciuria, hypohydroxiprolinuria. The changes are associated with the direct effect of thyroid hormones upon bone system (intensified bone metabolism with predominance of destruction). Calciuria and HOP-uria in thyrotoxicosis depend on the severity of the disease. The elevated calcium excretion in thyrotoxicosis speaks for the presence of ostemalacic component. TRP, PEI, mean diametrically opposite in hyper- and hypothyroidism, support the hypothesis of the secondary hypoparathyroidism in thyrotoxicosis and hyperparathyroidism--in the hypothyroidism.
