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

Figure 7 Effect of electrical stimulation of PVN on gastric mucosal proliferation induced by I/R at different times in rats. Sham: sham-operation; GI/R: reperfusion was maintained for 30 min, 1 h, 3 h and 6 h after 30 min of ischemia, respectively; PVN+GI/R: electrical stimulation of PVN plus GI/R. The percentage of proliferating cells was taken by using cell count in 10 microscopic fields (× 100). Each column represents an average value expressed in mean ± SE (n = 6). ^bP < 0.01, GI/R vs sham operation; ^aP < 0.05 and ^dP < 0.01, PVN + GI/R vs GI/R.
