Abstract
Serial measurement of serum electrolytes was made in 15 rabbits from 1 to 9 weeks after the unilateral constriction of renal artery. Blood pressure promptly rose and remained raised. Serum potassium decreased from a control value of 4.08±0.09mEq/l (mean±SE) to 3.55±0.14mEq/l one week after the constriction of renal artery and remained reduced during the postoperative 9 weeks. Serum chloride showed only a temporary decrease and serum sodium showed no significant change during the period of observation.
