Expression of GAP-43mRNA and VEGF-mRNA in different groups. Six rats' hippocampal specimens of freshly sampling from each group were used for the target RNA detection. Part A shows the amplification curves of actin-mRNA, GAP-43- mRNA, VEGF- mRNA; Part B shows the fusion curves of actin-mRNA, GAP-43- mRNA, VEGF- mRNA. The histogram of Part C shows the genes expression of GAP-43 and VEGF. Note: *: compared to Sham operated Group, P < 0.05; **: compared to Sham-operated Group, P < 0.01; #: compared to Model Group, P < 0.05; ##: compared to Model Group, P < 0.01.
