Figure 4.

Double immunofluorescence staining for DCX and p-CREB (A) and quantitative data (B) in the olfactory bulb of adult rats at 14 days post ischemia.

C’ and D’ are enlarged images of boxes in C and D, respectively. Scale bar: 100 μm in C and D; scale bar: 50 μm in C’ and D’. All data are expressed as the mean ± SD (six rats per group), and comparisons were conducted using one-way analysis of variance followed by Bonferroni post hoc tests. **P < 0.01, ***P < 0.001, vs. vehicle group. ns: P > 0.05, vs. vehicle group. TSPN: Total saponins of Panax notoginseng; p-CREB: phosphorylated cyclic adenosine monophosphate response element binding protein; GCL: granule cell layer; DCX: doublecortin.
