Curcumin significantly attenuated apoptosis after DAI. (a) TUNEL assay was used to detect apoptotic cells in the cortex of rats in each group. Immunohistochemistry of cleaved caspase-3 was performed to assess apoptosis in each group. Scale bar=100 μm. (b) The bar graphs show the results for the numbers of TUNEL and cleaved caspase-3-positive cells in each group. Values are presented as the mean±SD (n=4; *P<0.05, compared with the control group; #P<0.05, compared with the DAI+vehicle group). CUR, curcumin; DAI, diffuse axonal injury.
