The concentrations of insulin-like growth factor (IGF)-I and IGF-binding protein (IGFBP)-3 in serum obtained from 27 children with Perthes' disease and 10 age-matched control subjects were measured by radioimmunoassay (RIA). IGFBPs were also analyzed by a Western ligand blotting (WLB) method. The bone age was determined in 18 patients from hand-wrist radiographs. Serum levels of IGFBP-3 but not IGF-I were significantly lower than those in normal controls. WLB showed a decrease in the intensity of the IGFBP-3 band in 19 of the 27 patients. The bone age was delayed, 2 years or more compared with the chronological age in 7 of 18 patients, and all of them, except 1, showed decreased levels of IGFBP-3 on WLB. We conclude that there may be disturbances in availability of IGFs in some patients with Perthes' disease.

D011863	Radioimmunoassay	Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
