目的探讨莪术对缺血性脑中风的治疗作用及机制。方法健康成年雄性SD大鼠60只,随机分为假手术对照组、模型对照组、尼莫地平(20mg?kg-1)组、莪术(16,8,4g?kg-1)组,每组10只。除去假手术对照组,其余组大鼠采用线栓法制作大鼠大脑中动脉梗阻模型。造模前预防给药7次,造模后给药3次,每天一次。检测大鼠脑含水量、脑梗死体积百分比改变以及脑组织匀浆中MDA、NO的含量和SOD的活力。结果莪术(16,8,4g?kg-1)组脑梗死体积百分比和脑含水量为(13.7±1.6),(17.4±2.3),(24.9±2.9)%,(24.3±4.6),(32.2±6.8),(33.1±5.6)%,与模型组相比较,莪术(16,8 g?kg-1)组能明显降低大脑中动脉梗阻大鼠的脑梗死体积百分比和脑含水量;MDA、NO的含量为(5.08±0.15),(5.53±0.17),(6.03±0.37)nmol/mgprot,(2.64±0.19),(2.64±0.19),(3.31±0.15)μmol/gprot,与模型组相比较,莪术(16,8, g?kg-1)组能明显降MDA、NO的含量;SOD的活性为(124.14±7.51),(107.07±8.58),(105.42±9.39)U/mgprot,与模型组比较,莪术能明显升高SOD的活性。结论莪术对大鼠缺血性脑中风有一定的治疗作用,其机制可能与降低脑水肿、抗自由基及保护缺血区脑组织有关。
目的探討莪術對缺血性腦中風的治療作用及機製。方法健康成年雄性SD大鼠60隻,隨機分為假手術對照組、模型對照組、尼莫地平(20mg?kg-1)組、莪術(16,8,4g?kg-1)組,每組10隻。除去假手術對照組,其餘組大鼠採用線栓法製作大鼠大腦中動脈梗阻模型。造模前預防給藥7次,造模後給藥3次,每天一次。檢測大鼠腦含水量、腦梗死體積百分比改變以及腦組織勻漿中MDA、NO的含量和SOD的活力。結果莪術(16,8,4g?kg-1)組腦梗死體積百分比和腦含水量為(13.7±1.6),(17.4±2.3),(24.9±2.9)%,(24.3±4.6),(32.2±6.8),(33.1±5.6)%,與模型組相比較,莪術(16,8 g?kg-1)組能明顯降低大腦中動脈梗阻大鼠的腦梗死體積百分比和腦含水量;MDA、NO的含量為(5.08±0.15),(5.53±0.17),(6.03±0.37)nmol/mgprot,(2.64±0.19),(2.64±0.19),(3.31±0.15)μmol/gprot,與模型組相比較,莪術(16,8, g?kg-1)組能明顯降MDA、NO的含量;SOD的活性為(124.14±7.51),(107.07±8.58),(105.42±9.39)U/mgprot,與模型組比較,莪術能明顯升高SOD的活性。結論莪術對大鼠缺血性腦中風有一定的治療作用,其機製可能與降低腦水腫、抗自由基及保護缺血區腦組織有關。

Objective: To investigate the therapeutic effect and mechanisms of Ezhu on Ischemic Stroke. Methods:Sixty SD rats(maleness) were randomly divided into sham operation control group, model group, nimodipine tablets group, and EZhu(16,8,4 g?kg-1) groups.Except the sham operation control group, the other groups were established the middle cerebral artery obstruction model with the suture-occluded method. Each group was treated with corresponding drug preventability 7 times and 3 times after builded the model.Determination the cerebral water content, the cerebral infarction volume, the content of MDA and NO, the activity of SOD in the brain homogenate.Result:EZhu could lower the cerebral water content, the cerebral infarction volume. Significantly decreased the concentration of MDA and NO, improve the activity of SOD. Conclusions:The EZhu has obvious therapeutic effect on ischemic stroke mouse.The mechanism may be related to reduce cerebral edema, anti-free radical and protect the ischemia area of the brain.
