Fig 5. Concentration of trophic factors in CSF from SAH rats.
ELISA analysis was applied to measure the concentration of trophic factors in the CSF. The concentration of BDNF was significantly increased in the CSF collected from rats on days 5 and 7 post SAH as compared to that in the CSF from rats without SAH. The concentration of bNGF, EPO and EGF was increased in the CSF from rats on day 3 or 5 post SAH. Results of ELISA were analyzed by one way ANOVA with Tukey's multiple comparisons test. *, P < 0.05; **, P < 0.01, ***, P < 0.001 compared with CSF without SAH. ND, non-detectable.
