Embodiment 1

[0039] Example 1 Effect of Artemisinin on Neurological Function Evaluation of Cerebral Ischemia-Reperfusion Mice

[0040] Forty C57 / B6L mice were divided into 5 groups with 8 mice in each group. The body weight was weighed before administration, and the dosage was calculated according to the body weight. Group A is the blank control group (given with the same amount of normal saline); Group B is the model group (given with the same amount of normal saline); Group C is the model group + artemisinin 2 mg / kg; group D is the model group + artemisinin 6mg / kg; E group model group + artemisinin 18mg / kg. We used the middle cerebral artery occlusion method to create a mouse model of cerebral ischemia-reperfusion. After 1 hour of cerebral ischemia, the model mice were pulled out the thread plug, reperfused, and given different concentrations of artemisinin (2mg / kg, 6mg / kg and 18mg / kg) were administered intraperitoneally to middle cerebral artery occlusion model mice, and the neurolog...

[0043] Example 2: Artemisinin dose-dependent and time-dependent improvement of cerebral infarct size in mice with cerebral ischemia-reperfusion

[0044] Forty C57 / B6L mice were divided into 5 groups with 8 mice in each group. The body weight was weighed before administration, and the dosage was calculated according to the body weight. Group A is the blank control group (given with the same amount of normal saline); Group B is the model group (given with the same amount of normal saline); Group C is the model group + artemisinin 2 mg / kg; group D is the model group + artemisinin 6mg / kg; E group model group + artemisinin 18mg / kg. First, we used the middle cerebral artery occlusion method to create a mouse cerebral ischemia-reperfusion model. After 1 hour of cerebral ischemia in the middle cerebral artery occlusion model mouse, the thread plug was pulled out for reperfusion. When measuring dose-dependent cerebral infarct size, artemisinin (2mg / kg, 6mg / kg and 18mg / kg) of differen...

[0046] Example 3: Effect of Artemisinin on Cerebral Edema in Cerebral Ischemia-Reperfusion Mice

[0047] Forty C57 / B6L mice were divided into 5 groups with 8 mice in each group. The body weight was weighed before administration, and the dosage was calculated according to the body weight. Group A is the blank control group (given with the same amount of normal saline); Group B is the model group (given with the same amount of normal saline); Group C is the model group + artemisinin 2 mg / kg; group D is the model group + artemisinin 6mg / kg; E group model group + artemisinin 18mg / kg. First, we used the middle cerebral artery occlusion method to make a mouse cerebral ischemia-reperfusion model. After 1 hour of cerebral ischemia, the thread plug was pulled out and reperfusion was performed. At the same time, different concentrations of artemisinin (2mg / kg, 6mg / kg , 18mg / kg) were administered to mice by intraperitoneal injection, and the water content in the brain was measured by d...

Abstract

The invention discloses an application of artemisinin in the prevention and treatment of cerebral apoplexy. Artemisinin is low in side effect, and the neurological functions of an ischemic mouse witha cerebral ischemia reperfusion symptom are improved by activating an ERK1/2 signal channel in the brain of the mouse; and the encephaledema and oxidative damage of the ischemic mouse with the cerebral ischemia reperfusion symptom are relieved, the cerebral infarction area of the mouse with the cerebral ischemia reperfusion symptom is reduced, and the nerve cell apoptosis, loss and the like of themouse with the cerebral ischemia reperfusion symptom are reduced, so that artemisinin has positive effects on the improvement of cerebral apoplexy.

Description

technical field [0001] The invention relates to the application field of traditional Chinese medicine monomers, in particular to the application of artemisinin in the prevention and treatment of stroke. Background technique [0002] At present, stroke is the first cause of death in my country and the leading cause of adult disability. The morbidity, mortality and disability of stroke are high, and there is no safe and effective drug for the treatment of stroke. [0003] The oxidation state of TTC (2,3,5-triphenyltetrazolium chloride) is colorless and can be reduced by hydrogen to the insoluble red trityl trityl (TTF). Soak the brain tissue in an aqueous solution of TTC so that it penetrates into the cells of the brain tissue. If the cells have vitality, the dehydrogenase in them can use TTC as a hydrogen acceptor to reduce it to trityl and turn red (normal brain Tissue is stained red), or pale if it is an infarcted area. The calculation formula of Belayev et al was used t...
