[Study of immunological parameters in radiography and excretory urography].

Some immunological parameters (levels of serum complement, content of circulating immune complexes, and serum concentrations of immunoglobulins) were examined in patients after excretory urography by using triombrast and after X-ray studies without applying any contrast substance. Some changes were found in the activity of complement and in the concentration of immunoglobulins following intravenous triombrast injection. In addition, the above parameters were evaluated in patients with adverse reactions during the contrast study. The findings are discussed in terms of the immunotropic effects of triombrast.
