Abstract
Background: Traditional Chinese medicine has a long history of treating intracerebral injury. The aim of this research is to test the hypothesis that Ginsenoside Rg1 can alleviate brain injury in subarachnoid hemorrhage (SAH) mice. Methods: SAH mice were induced by autologous blood injection into cisterna magna, the mortality and neurological function were assessed. Ginsenoside Rg1 was administered continuously for seven days after SAH. Then, Y-maze test was used to detect the neurological deficits. Brains were harvested to evaluate the neuroinflammation of SAH by immunofluorescence staining and flow cytometry. Cerebral vasospasm was evaluated by hematoxylin-eosin (HE) staining, and neuronal apoptosis was evaluated by TdT-mediated dUTP Nick-End Labeling (TUNEL) staining and HE staining. Results: We demonstrate that Ginsenoside Rg1 reduced mortality and improved neurological deficits, reduced inflammatory response, ameliorated cerebral vasospasm and neuronal apoptosis after SAH. Conclusion: Ginsenoside Rg1 can alleviate brain damage after SAH in mice.
