[Nitroblue tetrazolium reduction by the neutrophils of the cerebrospinal fluid and peripheral blood and by the monocytic-reticular cells of the cerebrospinal fluid in neuroinfections].
Using the method of Park et al. the author studied spontaneous and stimulated NBT reduction by neutrophil granulocytes in the cerebrospinal fluid and blood, and by monocytic-reticular cells in the cerebrospinal fluid of the patients with bacterial and viral meningitis and meningismus. The author performed 333 investigations in 74 patients. Significantly higher mean values of the index of spontaneous and stimulated NBT reduction by the granulocytes and cerebrospinal fluid were observed in cases of bacterial meningitis as compared with the granulocytes of the peripheral blood in healthy subjects. It was demonstrated that in patients with bacterial meningitis blood and fluid granulocytes showed a similar phagocytic acitivty independent of the humoral environment. In the patients with bacterial and viral meningitis the monocytic-reticular cells the cerebrospinal fluid showed a similar, sometimes high, phagocytic activity depending on the phase and severity of the disease. On the otherhand, in most cases of meningismus these cells failed to manifest any phagocytic and bactericidal activity. In only few isolated cells in the fluid weak NBT reduction was observed. The obtained results of investigations showed the usefulness of the NBT test not only for the differential diagnosis of the aetiology of neuroinfections but also for the assessment of immune processes taking place in the nervous system.
