To observe the relationship among amyloid beta-peptide (Abeta)-induced neurotoxicity, serum-inducible kinase (SNK)-spine-associated Rap guanosine triphosphatase activating protein (SPAR) pathway and N-methyl-D-aspartate receptor (NMDAR), and to explore the mechanism of the protective effect of spleen-yin nourishing recipe (Zibu Piyin Recipe, ZBPYR) in hippocampal neurons against Abeta-induced neurotoxicity.
