Morphometric Changes in Lung Tissue During Chemical Burn of the Digestive Tract

Abstract

Lung pathology is quite widespread and has been studied in detail by both
clinicians and morphologists. But morphometric changes in lung tissue during a chemical burn of
the digestive tract have been poorly studied and require further research. In case of a chemical
burn of the digestive tract with acetic acid, such morphological changes were revealed as
pulmonary edema, a decrease in the volume fraction of the alveoli, destroyed epithelial cells and
red blood cells were detected in the lumen of the alveoli, thickening of the interalveolar septa and
an increase in their volume fraction were noted, which is associated with dystrophic changes in
the alveolocytes and endothelium of the blood vessels. blood vessels and swelling of the interstitial
tissue of the alveoli. As a result of developed edema and destructive changes, the relative volume
of collagen and reticular fibers in the lung stroma decreases. A slight leukocyte infiltration is
detected paravasally.
