OBJECTIVE To explore the effects of allicin on the changes of hemorheology in focal cerebral ischemia-reperfusion injury in rats. METHODS 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. RESULTS 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. CONCLUSIONS Allicin has protective effects on cerebral ischemia-reperfusion injuries. The mechanism may be related to inhibit the increasing of hemorheology.

D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.	Randomization,Allocation, Random
D001809	Blood Viscosity	The internal resistance of the BLOOD to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as SICKLE CELL ANEMIA and POLYCYTHEMIA.

D005737	Garlic	A species of Allium used as a spice (SPICES) and traditional remedy. It contains alliin lyase and alliin, which is converted by alliin lyase to allicin, the pungent ingredient responsible for the aroma of fresh cut garlic.	Allium sativum
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
