Gastric Mucosal Lesions in Tibetans with High-Altitude Polycythemia Show Increased HIF-1A Expression and ROS Production

<div>Ultrastructure of the gastric mucosa in the high-altitude polycythemia group double staining of both uranyl acetate and lead citrate ×10 000. Transmission electron microscopy of epithelial cells of the gastric mucosa in high-altitude polycythemia group (a), swelling of endoplasmic reticulum (A), mitochondria edema (B), and lymphocytic infiltration (C); control group (b), the epithelial cell structure of the gastric mucosa appeared normal.</div>
