ginsenoside rb/ischemia

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

OBJECTIVE To investigate the protective effects of ginsenoside Rb(3), a triterpenoid saponin isolated from the leaves of Panax notoginseng, on ischemic and reperfusion injury model of PC12 cells and elucidate the related mechanisms. METHODS PC12 cells exposed to oxygen and glucose deprivation (OGD)

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

The correlation between protective effect of ginsenosides Rb + R0 and brain endogenously-derived prostacyclin synthesis, thromboxane A2 formation and lipid peroxidation were estimated in rats. Ginsenosides Rb + R0 100 mg/kg iv 30 min before 4-vessel occlusion elevated 6-keto-PGF1 alpha level,

American ginseng (Panax quinquefolius) is a major species of ginseng that has many pharmacological effects. Studies have demonstrated that constituents of ginseng have neuroprotective effects during ischemia. Neuronal damage during ischemic episodes has been associated with abnormal Na(+) fluxes.

Salvianolic acid B (SAB), tanshinone IIA (TS), ginsenoside Rb₁ (Rb₁), ginsenoside Rg₁ (Rg₁) and notoginsenoside R₁ (R₁) are major active ingredients of Fufang Danshen preparation (FDP) for its protective effects on myocardial ischemia. This study investigated the pharmacokinetics of marker compounds
