To explore the effects of allicin on the changes of hemorheology in focal cerebral ischemia-reperfusion injury in rats.
Middle cerebral artery occlusion (MCAO) was used to make focal cerebral ischemia-reperfusion model by intravascular nylon filament occlusion. The protective effects of allicin at different doses were evaluated by investigating neurological function score, infarction volume and water content of brain. The changes of blood rheology were detected.
Compared with model group, allicin (15, 25 mg x kg(-1)) increased the neurological function score and decreased the water content and infarction volume of brain in rats. Allicin (15, 25 mg x kg(-1)) inhibited the increasing of the blood viscosity, high shear rate reduced viscosity, high shear relative reduced viscosity and low shear relative reduced viscosity.
Allicin has protective effects on cerebral ischemia-reperfusion injuries. The mechanism may be related to inhibit the increasing of hemorheology.
探讨大蒜素对大鼠局灶性脑缺血再灌注损伤血液流变学变化的影响。
采用血管内尼龙丝阻塞法制备大脑中动脉闭塞(MCAO)局灶性脑缺血再灌注模型。通过观察神经功能评分、脑梗死体积及脑含水量,评估不同剂量大蒜素的保护作用。检测血液流变学变化。
与模型组相比,大蒜素(15、25mg·kg⁻¹)可提高大鼠神经功能评分,降低脑含水量及脑梗死体积。大蒜素(15、25mg·kg⁻¹)可抑制血液黏度、高切变率降低黏度、高切相对降低黏度及低切相对降低黏度的升高。
大蒜素对脑缺血再灌注损伤具有保护作用。其机制可能与抑制血液流变学升高有关。
