Neuroprotective effects of Diospyros kaki and Gardenia jasminoides against ischemic neuronal injury in mice.

Tóm tắt

This study aims to clarify the neuroprotective effects of ethanol extracts of Diospyros kaki (DK) leaves and Gardenia jasminoides (GJ) fruit on cerebral ischemia injury using middle cerebral artery occlusion (MCAO) model in mice. Swiss albino mice were daily treated with DK extract (125-500 mg/kg b.w) and GJ extract (250-1,000 mg/kg b.w) for 1 week before being subjected to MCAO. The administration of edaravone (6 mg/kg, i.v), which was a reference drug, was started immediately after MCAO. DK and edaravone treatment improved neurological deficits and reduced infarct volume of MCAO mice compared to that of a vehicle-treated one. GJ treatment improved neurological deficits, but did not affect the infarct volume of MCAO mice. These results suggested that the DK and GJ treatment might be beneficial for protecting the neuronal system against cerebral ischemic injury.
