Effects of hypothalamic paraventricular nuclei on apoptosis and proliferation of gastric mucosal cells induced by ischemia/reperfusion in rats

Figure 6 Histological exhibition of electrical stimulation of PVN on gastric mucosal cellular proliferation induced by I/R at different times in rats. Proliferating-positive cells were probed with anti-mouse anti-proliferating cell nuclear antigen (PCNA) antibody and counter stained with hematoxylin in gastric mucosa (× 100). A: normal control gastric mucosa; B: gastric mucosa after sham operation; C: GI/R, 1 h after reperfusion; D: PVN + GI/R, 1 h after reperfusion; E: GI/R, 6 h after reperfusion; F: PVN + GI-R, 6 h after reperfusion; G: negative control group.
