title: [The effect of hormones regulating calcium metabolism on the growth and metastasis of experimental tumors].
abstract: Injection of parathormone and thyrocalcitonin into rats with DMBA induced sarcomas resulted in a considerable stimulation of the metastasization process. It was found that the level of total Ca++ in tumor tissue was reduced under the influence of PTH. Under conditions of chronic exogenous hyperparathyroidism autoimmunereactions were suppressed. A prolonged administration of TCT did not alter considerable the total Ca++ content in tumor and markedly activated the autoantibody production in immunocompetent cells.
