[Ultraweak luminescence of blood plasma in experimental embolism of the main arteries of the limbs].

The changes in the level of blood plasma chemiluminescence initiated by hydrogen peroxide and divalent iron were studied in experiments on 15 dogs with aorta bifurcation embolism. After occlusion of the arteries the level of iron-initiated chemiluminescence decreases. The level of hydrogen peroxide-initiated luminiscence increases simultaneously, reaches the maximum after 6-hour occlusion and subsequently tends to decrease. Hydrogen peroxide-initiated statistically significant increase in luminescence allows one to form a judgement about duration of the disease. After blood flow recovery in the limbs there take place a rise in the level of hydrogen-peroxide initiated hemiluminescence and subsequent iron-initiated hemiluminescence level drop.
