title: Coenzyme alterations in rats with experimental hypertension.
abstract: The changes in the content of pyridine nucleotide coenzymes (NAD+ and NADH) in several models of experimentally induced hypertension, differing in mechanism (genetic spontaneous hypertension, renal one kidney Goldblatt hypertension, Adrenal-regeneration hypertension after INGLE-HIGGINS and Skelton, and NaC1 hypertension) were studied. An obvious difference between the changes in NAD+ and NADH in the various models of hypertension, was established: Thus in NaC1 hypertension a high level of the coenzymes in the kidneys and in the vessel wall was found, while the liver coenzyme content was in normal ranges. In ARH the coenzyme level was elevated not only in the kidneys and in the vessel wall, but in the liver as well. Treatment with hypotensive antilipolytic prostaglandin E1 decreased the coenzymes in ARH to normal values. Renal hypertension was characterized by a low content of oxidized NAD, an increased NADH, and a decreased NAD+/NADH ratio in the kidneys and the liver, while in the vessel wall the coenzyme level was moderately increased. The coenzyme changes in the kidneys of SHR were similar to those in renal hypertensive rats. However coenzyme level in the vessel wall of SHR was lower than in all the other forms of hypertension.
