Oral administration of red ginseng powder before but not after transient forebrain ischemia prevents delayed neuronal death in gerbils. One neuroprotective molecule within red ginseng powder is ginsenoside Rb(1). The mechanism of action(s) of ginsenoside Rb(1) remains to be determined. We performed
Almost all agents that exhibit neuroprotection when administered into the cerebral ventricles are ineffective or much less effective in rescuing damaged neurons when infused into the blood stream. Search for an intravenously infusible drug with a potent neuroprotective action is essential for the
The aim is to study the effect of astragaloside Ⅳ (AST Ⅳ) combined with Panax notoginseng saponins (PNS) on cerebral ischemia-reperfusion injury, and to probe the synergistic mechanism through the pharmacokinetics of the four major components such as AST Ⅳ, ginsenoside Rg₁ (Rg₁), ginsenoside Rb₁
