[Serum haptoglobin in lung cancer patients]

Changes in the concentration of haptoglobin-glycoprotein-globulin fraction of blood serum were studied in patients with lung cancer. It was found, that haptoglobin concentration increased in accordance to a disease stage. Formation of haptoglobin hemoglobin (Hp-Hb) complex in the sera of patients may be of great importance for neutralization of superoxidative products.
