Abstract:
To investigate the antagonism effects of different concentrations of ginkgolide K(GK) on platelet activating factor (PAF)-induced platelet aggregation and neuroprotective effect on cells and animal models of ischemia-reperfusion injury. GK-containing serum in rabbit was prepared, and the effects of GK-containing serum on PAF-induced platelet aggregation was observed by platelet aggregation assay. The effect of different concentrations of GK on apoptosis of SH-SY5Y cells injured by oxygen-glucose deprivation/reoxygenation (OGD/R) was investigated by Hoechst 33342/PI double staining in OGD/R cell model. The focal cerebral ischemia-reperfusion model (I/R)was established in rats to detect the effects of GK on neurobehavioral scores and cerebral infarction volume. GK could inhibit PAF-induced platelet aggregation, reverse the apoptosis induced by OGD/R injury and improve the neurobehavioral score and cerebral infarction volume after cerebral ischemia-reperfusion injury in rats in a dose-dependent manner. GK can inhibit PAF-induced platelet aggregation and improve nerve injury after cerebral ischemia-reperfusion.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
