Level of neurotransmitters in neuroamine-containing lung structures in different forms of tuberculosis
The aim of the study was to identify the features of variations in the localization of monoamines (catecholamines, serotonin)in the cell structures of autopsy material of lungs affected by tuberculosis. Material and methods. 165 cases of secondary pulmonary tuberculosis were studied. We studied 2500...
