Abnormalities of serum proteins following thermal injury

Suppressive factors were found to be present in serum and considered to be one of the causes of the suppression of body defences following thermal injury. The purpose of this study was to find out any abnormality of the postburn serum proteins by the comparison of burned and normal sera using immunoprecipitation in gel. The results of SDS-polyacrylamide gel electrophoresis, crossed immunoelectrophoresis, tandem crossed immunoelectrophoresis, and fused rocket immunoelectrophoresis showed that differing precipitation bands or peaks existed between burned and normal sera, and abnormal constituents with relatively low molecular weight were present in the burned serum.
