[R proteins as a reflection of disorders in the cellular reception mechanisms in kidney diseases].

As many as 47 patients with amyloidosis and 31 with chronic glomerulonephritis (CGN) were examined for the blood serum content of R proteins, chemotactic activity of blood leukocytes and the degree of the inhibitory influence of the autologous serum on chemotaxis. Amyloidosis and CGN were marked by an increase of the level of receptor proteins. A reverse correlation was established between the rise of the content of R proteins and the chemotactic properties of leukocytes. In CGN, the rate of demonstration of the high titers of R proteins and the magnitude of the chemotaxis decline depended on the disease phase (the degree of activity) whereas in amyloidosis, these reactions differed insignificantly in patients with various clinical patterns and stages of renal amyloidosis.
