Factors influencing intercellular spaces in the rat esophageal epithelium

Figure 1 Transmission electron photomicrographs of the esophageal epithelium, showing intercellular spaces in rats of different groups in Part I (A-H) and Part II (I-L) (magnified at × 5000 by transmission electron microscopy). A: Normal control group; B: Normal saline (NS) intragastric administration group; C: NS hypodermic injection group; D: Water immersion and restraint stress (WRS) group; E: Hydrochloric acid intragastric administration group; F: Ethanol intragastric administration group; G: Aspirin intragastric administration group; H: Prednisolone hypodermic injection group; I: NS + WRS group; J: Esomeprazole + WRS group; K: NS + aspirin group; L: Esomeprazole + aspirin group.
