Intravenous acid fibroblast growth factor protects intestinal mucosal cells against ischemia-reperfusion injury via regulating Bcl-2/Bax expression

Figure 2 The expression of bcl-2 protein in sham-operated control group (A), 6 h after ischemia-reperfusion in group R (B) and 6 h after ischemia-reperfusion in group A (C) bcl-2 was strongly expressed in the sham-operated intestinal tissues and positive particles of bcl-2 were mainly localized in the lower half of the villus and in the cytoplasm and nuclei of villus cells. bcl-2 expression level decreased at 6 h after reperfusion in group R. Compared with group R, the positive cellular rates of bcl-2 were significantly higher at 6 h after reperfusion in group C.
