Blood was taken for measurement of plasma renin activity (PRA); then captopril (0.7 mg/kg of body weight) was administered orally. A second blood sample was taken for PRA at 90 min postcaptopril.

Some individuals had PRA values as high as those of patients with renovascular disease, but the etiology of their hypertension was usually clinically evident.

However, the somatomedin bioactivity of uremic serum is depressed, and unsaturated low-molecular-weight IGF-I-binding proteins have been suggested to act as inhibitory factors of IGF-I action.
