title: Electron Microscopic Characteristics of The Blood-Air Barrier Interstitium in Fibrous Cavernous Pulmonary Tuberculosis in Comparison with Chronic Nonspecifi c Lung Diseases
abstract: Aim . To describe the ultrastructural characteristics of the blood-air barrier (BAB) interstitium in fi brous cavernous pulmonary tuberculosis (FCT) in comparison with chronic nonspecifi c lung diseases (CNSLD). Materials and methods . The fragments of the pericavernal zone and lung tissue were taken for the study at the resection border from the dead or operated for CNSLD persons (n = 163), and the perifocal and boundary zone of lung tissue. 116 CNSLD patients were divided into 3 subgroups: 1)
