Figure 3.

The pathological changes of gastrointestinal tissue structures observed by a light microscope in the control and hypothermia groups. A: Gastric mucosa (×100) showing defect of mucosal epithelial cells (black arrow), the arrangement of cells in lamina propria layer loose and disordered, representing ischemic changes (white arrow head) in the control group; B: Gastric mucosa (×100) showing mucosal epithelium complete (black arrow head) in the hypertransfusion group; C: Intestinal mucosa (×100) showing the structure of intestinal villi basically complete, but the arrangement of cells irregular (black arrow) and a plenty of inflammatory cells in the mucosal layer (white arrow) in the control group; D: Intestinal mucosa (×400) showing the structure of intestinal villi complete and the arrangement of cells regular and dense (black arrow) in the hypertransfusion group.

Figure 4.

The pathological ultra-structural changes of gastric tissues observed with an electron microscope in the control and hypothermia groups. A: Gastric mitochondria were highly swollen; vacuole-like changes with ridges fragmental could be observed (black arrow) in the control group; B: The structure of gastric mitochondria was complete with their ridges relatively clear (black arrow) in the hypertransfusion group; C: Defect of part of intestinal microvilli (black arrow) in the control group; D: In the control group, the arrangement of intestinal microvilli loose (black arrow) and the structure of intestinal mitochondria not distinct with their ridges hazy (black arrow); E: The arrangement of intestinal microvilli dense and regular (black arrow) in the hypertransfusion group; F: The intestinal mitochondria with their ridges manifesting basically clear (black arrow) in the hypertransfusion group.
