Metformin Activates the Protective Effects of the AMPK Pathway in Acute Lung Injury Caused by Paraquat Poisoning

Figure 2

Effect of MET on changes in lung tissue structure induced by PQ in rats with ALI as determined by transmission electron microscopy. Changes of lung tissues after PQ exposure for 7 days were observed by transmission electron microscopy (magnification by 10000 times). The arrow indicates an inflammatory exudation. (a) Control group. (b) PQ group. (c) MET group. (d) PQ+MET group.
