چکیده انگلیسی
We studied the effects of benzydamine (BZ) and cyclophosphamide (CP) on acute lung injury caused by Tityus discrepans venom. Mice (male, IVIC strain, â25g) were pretreated with either BZ (20μg/g) or CP (100μg/g) i.p. or saline. Envenoming (2μg/g mouse) was induced sc. Lung fraction area occupied by fibrin (FF), nuclei (NF), alveolar space (AS) and parenchyma (PF) were determined. Venom increased FF, NF and PF, significantly, and decreased AS. BZ antagonised venom's effect on FF sharply, antagonised partially effects on PF and AS, but was not able to antagonise effect on NF. CP abolished venom effects on NF, AS and PF, but was not able to antagonise the effect on FF. CP was slightly less effective than BZ in reducing FF. Fibrin deposition was associated to leukocyte sequestration. Blocking pro-inflammatory leukocyte metabolic pathways with BZ diminished FF, suggesting that neutrophil activation, inflammation and coagulation are correlated in the genesis of scorpionism acute lung injury.
