Effect of Curcumine on Whole Blood Viscosity,Cerebral Homogenate ATP Enzyme and Morphology of Brain Tissue in Rat Cerebral Ischemia Model with Blood Stasis / 中药新药与临床药理

ABSTRACT

Objective To explore the effect of curcumine on rat cerebral ischemia model of blood stasis.Methods The blood-stasis rat model was established by injection of dexamethasone,then was given gastric infusion curcumine suspension for 10 continuous days.One hour after administration on the 11th day,we made ligation of the bilatory common carotid arteries of rats for 30 min to induce cerebral ischemia rat model.The rat blood sample was used for the detection of whole blood viscosity,and the brain was taken out for the observation of cerebral homogenate ATP and the pathological changes of brain tissue.Results The blood-stasis rats model was established successfully by intramuscular injection of dexamethasone,and cerebral ischemia rats model was established successfully by ligation of bilateral common carotid artery.Compared with the model group,curcumine could significantly reduce the whole blood viscosity of blood-stasis rats model of cerebral ischemia,and significantly increase the activity of Na+-K+-ATP,Mg2+ATP,Ca2+-ATP and Ca2+-Mg2+-ATP in brain homogenate,significant relieve the atrophy of nerve cells and glial cells of the model rats.Conclusion Curcumine can significantly improve the whole blood viscosity,ATP activity in the brain homogenate and morphological changes of brain tissue in rats model of blood stasis.
