to localize such a defect to specific segments of the nephron , we studied the activities of vp-sensitive adenylate cyclase , camp phosphodiesterase ( camp-pdie ) , as well as accumulation of camp in medullary collecting tubules ( mct ) and in medullary thick ascending limbs of henle 's loop ( mal ) microdissected from control mice with normal concentrating ability and from mice with hereditary ndi .
