| Sumario: | The narrowing of the lumen of the trachea due to cicatricial stenoses of the trachea is one of the urgent problems of the modern surgery. The processes taking place in the trachea and lungs lead to a change in the state of the immune system. Assessment of the dynamics of indices of nonspecific resistance is one of the methods for assessing the severity of the course of the disease. We studied the indices of nonspecific resistance of the organism in narrowing the lumen of the trachea in an experiment in the early postoperative period. The study was carried out on the basis of the scientific department of experimental surgery with the vivarium of Irkutsk Scientific Centre of Surgery and Traumatology, on 24 white male Wistar rats with a body weight of 300–350 g. We simulated narrowing the lumen of the trachea by placing a silicone tube in the lumen of the trachea for 14 days. The parameters of phagocytosis, the state of phagocytic activity of blood neutrophils, spontaneous NBT-test, induced NBT- test were studied. The animals were withdrawn from the experiment on the 3rd, 7th and 14th day. We revealed that as a result of narrowing of the lumen of the trachea with the original procedure, the nonspecific resistance of the organism was violated with inhibition of the phagocytic activity of leukocytes. There was inhibition of phagocytic activity of leukocytes and depletion of the functional reserve of leukocytes. |
