Abstract: | Immunoelectrophoresis was used to measure fibronectin content in blood plasma of 111 children with insulin-dependent diabetes mellitus and in 20 normal children. In patients with diabetes mellitus, the content of plasma fibronectin turned out to be higher depending on the disease standing, the presence of microangiopathies, and status of compensation. It has been noted that fibronectin was detectable in urine in diabetic angionephropathy. |
