Abstract
Aim.Detection and assessment of histomorphological changes in the lungs in acute poisoning with Baclofen and its combination with ethanol three hours after poisoning.Material and methods.Experimental studies were conducted in 15 Wistar lineage rats divided into three groups. The control group included five intact animals, group 1 was treated with Baclofen at a dose of 85 mg/kg, group 2 with a combination of Baclofen (85 mg/kg) and ethanol (7 mL/kg of 40% ethanol).Results.No pathological changes were observed in the lungs of the controls. Both treated groups manifested the capillary and venous plethora, sludge syndrome, atelectases and dystelectases, emphysema and infiltration of white blood cells into the interalveolar septa. Bronchioles in the group 2 animals contained secretion.Conclusion.In the conducted trials, a complex of pathological changes was observed in the lungs of animal models shortly after the administration of Baclofen, including circulatory disorders in all departments of the microcirculatory bed (plethora of capillaries and venules), emphysema, atelectases and dystelectases, leucocyte infiltration into the interalveolar septa. Morphometric studies are necessary to quantify the severity of histomorphological changes in the lungs.
