Antidiuretic hormone within the normal range and clinical significance

Antidiuretic hormone (also called vasopressin) by the hypothalamus, as the nucleus and paraventricular nucleus of nerve cells secrete the hormone-9, the hypothalamus - pituitary beam after the release of pituitary nerve to reach out. Its main role is to improve the distal convoluted tubule and collecting duct water permeability, and promote the absorption of water, concentrated urine is diluted and the key regulating hormones. Antidiuretic hormone (also called vasopressin) by the hypothalamus, as the nucleus and paraventricular nucleus of nerve cells secrete the hormone-9, the hypothalamus - pituitary beam after the release of pituitary nerve to reach out. Its main role is to improve the distal convoluted tubule and collecting duct water permeability, and promote the absorption of water, concentrated urine is diluted and the key regulating hormones. In addition, it Suibu hormone can enhance the collecting duct in the permeability of urea. Normal range: 1 ~ 10μu/mL. 11 ~ 30μu/24h. Inspection: The main role of antidiuretic hormone is to increase the kidney tubules far and collecting duct water re-absorption, a direct impact on the volume. Clinical significance: higher: found in the thyroid hormone, glucocorticoid and a lack of insulin, as well as the antidiuretic hormone secretion syndrome, tuberculosis, brain injury, congestive heart failure. Standing position at night, when the pain can pull to increase hormone secretion. Were taken tranquilizers, anti-hypoglycemic agents will enable the blood hormone level increased. Reduce: diabetes insipidus seen, nephrotic syndrome, as well as the lithium salt intake and drugs such as tetracycline.
