Representative photomicrographs of histological section of the lung of Wistar rats stained with hematoxylin and phloxine and observed under light microscope (bar = 150 μm). Extra-pulmonary acute lung injury was induced by a single dose of paraquat (PQ, 30 mg/kg, wt, i.p.) and the animals were treated with extract of Bathysa cuspidata (BCE 200 and 400 mg/kg, wt.) diluted in vehicle DMSO (VE). Control animals received saline (SAL), paraquat (PQ); vehicle DMSO (VE) or BCE 400 mg/kg alone.
