Figure 3. Compared with the Model group, the brain tissue and brain function damages were improved, mTOR was increased, and autophagy protein was significantly decreased in the Panax notoginseng group. (A) HE staining, Nissl staining and transmission electron microscopy of brain tissue. (B) The neural function defect score at 12h, 24h and 72h. (C) mTOR, p-mTOR, P62, Beclinl, LC3I and LC3II by Western-blotting. n=6.
