Evaluation of the granulocyte membrane potential of mitochondria in children with chronic inflammatory lung diseases
https://doi.org/10.25789/YMJ.2020.72.02
Abstract
The article presents the study of the characteristics of the membrane potential of mitochondria (MPM) granulocytes in 72 children with congenital lung malformations (CLM). There was a 5-fold increase in the proportion of cells with reduced granulocyte MPM(ΔΨm) compared to the control group. During the periods of exacerbation of the disease, the number of granulocytes with reduced potential increased by 8 times accompanied by the growth of luminol-and lucigenin-dependent chemiluminescence of whole blood phagocytes with spontaneous, significant decrease in the I-lum and I-luc stimulation indices by 30 and 25%. Negative dynamics of the stimulation index indicates the depletion of reserve capacities of the phagocytic system in children of the study group. There are statistically significant direct correlations between the level of granulocytes with reduced MPM(ΔΨm) and indicators of phagocytic activity of leukocytes.
