title: Cyclic nucleotide changes in aortic segments derived from hypertensive rabbits.
abstract: Mean blood pressure increase was produced by: (1) renal constriction plus contralateral nephrectomy, and (2) cadmium acetate ingestion. Blood pressure was measured directly via the middle ear artery. Cyclic nucleotide levels were determined by 125I-radioimmunoassay. Levels of cAMP were reduced in both hypertensive subgroups when compared to controls. The altered cAMP levels suggest a relationship of this nucleotide to the maintenance of increased blood pressure.
