Abstract: | High calcium diet induces an hypertension lasting one week in normal rats. In mineralocorticoid treated rats (DOCA + NaCl), the same diet prevents for 10 weeks the increase of arterial blood pressure. Parathyroid activity (estimated by urinary cAMP) is decreased after the high calcium diet. These results confirm the role of the parathyroid glands in mineralocorticoid hypertension in the rat. |
