Paper electrophoretic studies on serum protein changes in blast injury in rabbits.

Summary. 1 The changes in the serum protein fractions in rabbits exposed to a high explosive air shock wave were studied by means of paper electrophoresis. 2 The albumin and γ-globulin concentrations were decreased, the albumin content during the whole observation period of 10 days after the exposure, the γ-globulin only during the first, 4 days. 3 The a1- and a2-globulin fractions were slightly increased from the second to the fifth day but had generally been normalized again at the end of the observation period. 4 In some eases a strong although statistically not significant increase of the β-globulin fractions was noticed. This increase can partly have been due to a contribution from incompletely removed fibrinogen. 5 No changes were found in the total nitrogen content of serum.
