Effects of a Portable Peritoneal Lavage Device on Dogs with Seawater-Immersed Open Abdominal Injury

Figure 4

Ultrastructure of the liver, stomach, and small intestine cells in different treatment groups. Dogs were euthanized at 2 h after open abdominal injury, 3 h after the dogs were pulled up from seawater, 2 h after delayed lavage (group A), 2 h after timely lavage (group B), and 2 h after timely lavage with the device (group C). The small intestine and liver tissues were obtained immediately after the dogs were euthanized. After fixation, embedding and sectioning, the ultrastructure changes of the tissues were observed under a microscope (2000x).
