The enzyme histochemistry was studied in the lung of domestic fowl in normal state and after left pulmonary artery ligation (PAL). Immediately after PAL, non‐specific esterase activity increased in the epithelial cells and the tertiary bronchi. Naphthylamidase reaction increased intensely in the epithelium and adjacent structures after PAL. After PAL, air/ blood capillary network showed pronounced tetrazolium reductase activity in a corona‐like circle around bronchi. It was concluded that the active transport mechanisms seem to be disturbed immediately after PAL, but no severe ischaemic changes were observed. A temporary activation of energy yielding process was noted in the capillary network near the tertiary bronchi. A proliferative or inflammatory process is perceptible in the epithelium of the tertiary bronchi and the walls of the bronchial atria.
