Verapamil Inhibits Mitochondria-Induced Reactive Oxygen Species and Dependent Apoptosis Pathways in Cerebral Transient Global Ischemia/Reperfusion

Figure 6

Nissl staining of rats’ prefrontal cortex following transient global I/R and cell counting. The prefrontal cortex of control animals (a) did not contain any damaged neurons. However, the cortex of rats in the I/R (b) and I/R+NaCl (c) groups was characterized by fewer Nissl stain neurons (thin arrows) than that in the I/R+Ver group (d) and markedly contained shrunken, intensely stained, and dystrophic neurons (thick arrows). As shown in the graph (e), treatment rats with verapamil significantly reduced neuronal cell loss in the prefrontal cortex. Data are represented as . Scale bars 100 μm, magnification ×400. vs. control group, vs. I/R+NaCl and I/R groups.
