Objective: Ginsenosides, Rb1 and Rb3, are the major protopanaxadiol components of ginseng saponin. In the present study, the influences of ginsenosides Rb1 and Rb3 on N-methyl-D-aspartic acid (NMDA) receptor or DL-α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor-mediated synaptic transmission after oxygen-glucose deprivation (OGD) were investigated. Methods: NMDA receptor population spike (NMDA-PS) or AMPA receptor-mediated population spike (AMPA-PS) was recorded in the CA1 pyramidal cell layer of rat hippocampal slices by electrophysiological techniques. Results: Under normal conditions, ginsenosides Rb3 and Rb1 depressed glutamate receptors-mediated synaptic transmission. Fourteen min of OGD resulted in a poor recovery amplitude of NMDA-PS or AMPA-PS after reoxygenation. Ginsenoside Rb3 significantly delayed the appearance of transient recovery of PS during OGD, and improved the recovery amplitudes of NMDA-PS and AMPA-PS after reoxygenation. However, the similar protective effects of ginsenoside Rb1 were observed only on NMDA-PS but not AMPA-PS. Conclusion: These results suggest that ginsenosides Rb1 and Rb3 have the different inhibitions on NMDA and AMPA receptors-mediated response, which may partially explain the different protective effects of these agents on ischemic neuronal death.
