Extract of Fructus Cannabis Ameliorates Learning and Memory Impairment Induced by D-Galactose in an Aging Rats Model

Figure 8

Effect of EFC on the expression of presenilin 1, total tau, and p-tau in the hippocampus of aging rats induced by D-gal. The relative protein levels between the tested target protein and internal standard GAPDH were calculated and labeled on -axis. Data are expressed as the mean ± SE (). as compared to the normal control group. as compared to the D-gal model group. The bands are from a representative blot. Lane 1: normal control group; lane 2: D-gal-treated group; lane 3: EFC treatment group; lane 4: D-gal plus EFC (400 mg/kg) treatment group.
