Plasma levels of AVP.

November Pages Transsphenoidal neurosurgery of intracranial neoplasm. This phosphorylation promotes movement of the vesicles towards the apical membrane of the tubular lumen, which leads to the exocytic formation of aquaporin-2 vesicles located in the cellular membrane. Its synthesis is accompanied by the generation of a specific carrier protein called neurophysin II. When adequate stimuli are received, the hormone is secreted together with neurophysin by means of exocytosis.

The histological characteristics of the Neuro hypophysis are described as well as its morphological functions related to the hypothalamus. Infants frequently cannot drink sufficient fluids to compensate for urinary losses. With these urine samples the osmolality and density and the amount of urine will be determined.

Therefore, it is necessary to administer a potassium supplement. The V 2 receptor, which is found in the vascular endothelium and in the principal cells of the connecting and collecting tubules of the diabetss, induces the release of factor 8 and von Willebrand factor and mediates the hydro-osmotic effect of the AVP. A Prospective study of 23 cases. This item has received.
