Polyacrylamide gel electrophoretic serum protein patterns of acute inflammation induced by intramuscular injection of turpentine in young broiler chickens.

Changes in the serum protein patterns accompanying inflammation in young broilers were examined by polyacrylamide gradient gel electrophoresis. Sera were obtained from blood of 4-week-old male broilers after induction of acute inflammation by an injection of 0.5 ml/kg turpentine. Electrophoretic patterns at 48 hr after injection, showed an increase in transferrin (Tf) and a segment containing albumin (Alb) with multiple peaks. The unbound iron binding capacity (UIBC) increased by 10 times, and the serum iron (SI) concentration in acute inflammation was reduced to one-half its initial value. These are considered to be typical changes in serum proteins and iron after acute inflammation.
