Figure 4. Effect of SEW2871 on Aβ-induced damage in CA1 region of rat hippocampus. Investigation of Nissl stained photomicrographs from CA1 region of hippocampus showed that the pyramidal cells layer in CA1 area of Aβ1-42-injected rats are markedly thinner than that in the control group. While in AD rats which chronically received SEW2871 it was as thick as that in control group. From left to right: control, Aβ, Aβ + SEW groups. Photos represent ×400 magnification.
