[Morphometric analysis of the effects of vasopressin in the rat kidney collecting tubules].
A significant increase in the water permeability was found in the rat outer medullary collecting duct (OMCD) cells in presence of 10-7M of vasopressin. The latter caused a decrease in the OMCD cell volume in isoosmotic medium in adult rats. In pups, the water permeability of the OMCD cells was very high. Vasopressin seems to be unable to decrease the cell volume of the OMCD cells in pups which suggests an immaturity of the cell transduction mechanism.
