Figure 4. Compared with the Rapamycin group, the brain tissue and brain function damages were improved, and autophagy protein was significantly decreased in the Panax notoginseng group and Panax notoginseng+Rapamycin 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, LC31 and LC3ll by Western-blotting. n=6.
