to study the resistance of normotensive vascular beds in coarctation hypertension , we measured perfusion pressures of pump-perfused ( blood ) , innervated , isolated hindlimbs of 12 rats ( group a ) with 4 weeks of hypertension due to partial contriction of the abdominal aorta above the renal arteries , and of three control groups : 11 normotensive rats ( group b ) with aorta sham-constricted , nine normotensive rats ( group c ) with slight ( 5 % ) hindquarters atrophy due to partial constriction of the abdominal aorta below the renal arteries , and six rats with two-kidney , one clip goldblatt hypertension ( group d ) .
