[Reciprocal relationship between bones, hematopoiesis and kidney with reference to sex hormoses. 2. Endocrine osteopathy and sex hormones].

Interactions and influence between blood and bone-tissue are discussed. In chronic renal insufficiency there is a failure of the kidneys as an endocrine organ with hormones for hemopoiesis and bone-metabolism. This deficit can partly or completely be replaced by an appropriate therapy. The--in the kidney transformed and so activated--vitamine-D-metabolite 1,25(OH)2D3 can be used in the therapy of osteoporosis, the combination with sodium fluoride brings even better results. In cases of postmenopausal osteoporosis and lack of estrogen estrogens are indicated for the treatment and the prophylaxis of osteoporosis.
