Abstract
Summary
1) Mesenteric arteries of rats with acute renal hypertension were analyzed for electrolyte and water content. A technic is described for obtaining these vessels. 2) Arteries showed a significant rise in sodium, potassium, and chloride, as well as expansion of total water. However, total cation concentration in tissue water was not significantly altered. 3) Electrolyte changes may have resulted from renal dysfunction associated with retention of salt and water. Whether they were incidental to the hypertensive state or played a role in its genesis is not established.
