Pretreatment of cromolyn sodium prior to reperfusion attenuates early reperfusion injury after the small intestine ischemia in rats

Figure 2 Changes of ultrastructure of small intestinal in each group (× 10 000). The ultrastructure of small intestinal was normal in group S. There were seen the karyopyknosis of epithelial cell of small intestine in group M, and the nuclear membrane was more irregularity, and the swelling microvillus became shorter and thicker, most of the microvillus were shedding. The nucleus of epithelial cell of small intestine in group C1 and C2 was deflated, the nuclear membrane was irregularity, and the microvillus became shorter and light swelling.
