[Antimicrobial activity of blood phagocytes in patients with tuberculosis and respiratory sarcoidosis]
Abstract:
Examination of 82 patients has revealed that pulmonary tuberculosis is characterized by a considerable increase in the antimicrobial activity of phagocytes: the drastic elevation of the plasma level of neutrophilic elastase and the changes opposite in direction in the phagocytic content of nonenzymatic cation proteins and myeloperoxidase. There is evidence for that the activation of circulating phagocytes is much less pronounced in patients with respiratory sarcoidosis. The significantly less plasma activity of neutrophilic elastase and the significantly greater phagocytic values of cation proteins suggest that the synthesis of secretion products prevails over their degranulation in sarcoidosis. It has been shown that the simultaneous determination of nonenzymatic cation proteins and myeloperoxidase in the phagocytes of patients allows the diagnosis to be established in 33.3% of cases.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
