Cytochemical study of immune processes in newborns with acute respiratory infections

At various stages of the immune process in 101 newborns with acute respiratory infections, the glycogen content in lymphocytes and neutrophils, neutrophil phospholipids and the activity of acid and alkaline phosphatases in them, the activity of succinate dehydrogenase of lymphocytes and the average content of lysosomes in them, as well as the activity index of monocytes were studied. The peculiarities of the dynamics of cytochemical parameters were revealed depending on the premorbid background, the phase of the disease, the presence of bacterial concomitant diseases and superinfection with acute respiratory infections. The calculation of the average content of lysosomes in lymphocytes and the activity index of monocytes can be recommended for use in clinical laboratories of the departments of neonatal pathology.
