Problems solved by technology

[0004] At present, there is no research report on whether the three-lens component in the three-lens has an anti-ischemic stroke effect. To study whether the three-lens component in the three-lens has an anti-ischemic stroke effect can make up for the gap in the prior art, and It is of great significance to guide the development of clinical medication and new drugs

Abstract

The invention discloses an application of scirpusin A to preparation of medicines for resisting stroke. Specifically, through research, the inventor of the invention finds that the scirpusin A has remarkable restraining effects on injury due to calcium ion overload and injury due to oxygen-glucose deprivation, can improve neurological function defective symptoms, can notably reduce the cerebral infarction area and cerebral indexes of a bandicoot suffering from cerebral ischemia-reperfusion injury, can notably reduce the levels of TAX2, ET-1, TNF alpha, IL-beta and MDA in serum and LDH activity, besides, has the effects of improving blood-brain barriers and protecting neuronal cells, and is remarkable in treatment effects and small in usage dosage when being used for treatment of the stroke. In addition, the scirpusin A is an effective component of a traditional Chinese medicine namely rhizoma spargani, is extensive in sources, safe and low in toxicity, provides a new selection and powerful basis for development of natural medicines for resisting the stroke, and has wide development space and favorable application prospects.

Description

technical field [0001] The invention belongs to the technical field of medicine. More specifically, it relates to the application of trigonin A in the preparation of anti-ischemic stroke medicine. Background technique [0002] Ischemic stroke (Stroke) is a general term for brain tissue necrosis caused by stenosis or occlusion of cerebral blood supply arteries (carotid artery and vertebral artery) and insufficient cerebral blood supply. Cerebral ischemia includes four types, divided into transient ischemic attack (TIA), reversible neurological deficit (RIND), progressive stroke (SIE) and complete stroke (CS). TIA has no cerebral infarction, but RIND, SIE and CS have different degrees of cerebral infarction. At present, the methods for treating ischemic stroke are mainly taking chemical drugs or surgical treatment. The prognosis of the disease is poor, there is a certain rate of disability and death, and recurrent attacks can occur; in addition, chemical drugs have strong to...
