Figure 1
The effects of Mangxiao or Dahuang on COPD-like rats’ lung histopathology (H&E stain ×100). Histological examination of lung tissues was performed 48 h after the final administration. Lung tissues were fixed, sectioned at 4 μm thickness, and stained with H&E solution. (a) Control group: received room air, intratracheal normal saline instillation, and intragastric administration of water. (b) Model group (LPS + cigarette): received cigarette smoking, intratracheal LPS instillation, and intragastric administration of water. (c) Mangxiao group (LPS + cigarette + Mangxiao): received cigarette smoking, intratracheal LPS instillation, and intragastric administration of Mangxiao (1.5 g/kg) decoction. (d) Dahuang group (LPS + cigarette + Dahuang): received cigarette smoking, intratracheal LPS instillation, and intragastric administration of Dahuang (1.5 g/kg) decoction.
