RESUMO
Any lesion in organism, causing the development of inflammation, is followed by changed work of the immune system that is extremely important for prognosis of the course of the pathological process. The adequate compensation-defense reaction was estimated using well-known immunological tests and normal reaction of the immune system was determined to be different from the pathological reaction, especially in patients in critical state. The adequate reaction of the immune system is characterized by mild leukocytosis, two-three fold increase of the spontaneous HCT test, normal or moderately pronounced indices of the cellular and humoral links of immunity. The markers of the formation of secondary immune incompetence are not only decreased but also extremely increased indices of immunogram at early terms of the disease.
