Analysis of the Cellular Composition of Bronchoalveolar Lavage in the Modeling and Treatment of Acute Respiratory Distress Syndrome in Biomodel Mice

Abstract

This article investigates changes in the cellular composition of bronchoalveolar lavage over time in the modeling of acute respiratory distress syndrome (ARDS) in mice, followed by a single administration of Leutragine. In intact animals, macrophages predominate in bronchoalveolar lavage, which is the physiological norm. When modeling ARDS, neutrophils increase. A single administration of Leutragine leads to a significant reduction in the number of neutrophils and a simultaneous increase in macrophages in 72 hours, thus bringing the cellular composition of lavage to normal.
