This topic in order to reveal the mechanism of acupuncture treatment of cerebral infarction , cerebral artery occlusion (MCAo) causing focal cerebral infarction in rats as a model , to the impact of acupuncture on cerebral ischemia leptomeningeal microcirculation theme , using microscopic video devices combined with vascular endothelial cell staining and leukocyte fluorescent tracer method , dynamic quantitatively observed 3, 6, and 24 hours after MCAo leptomeningeal microvascular density , self-discipline and the frequency and amplitude of the movement , blood flow velocity and other changes , as well as the Effect of Acupuncture . The results are as follows : 1 , 3, 6, and 24 hours after MCAo leptomeningeal microvascular density of the ischemic area decreased significantly , while acupuncture the microvascular open can increase the density increases . Acupuncture can promote the establishment of collateral circulation in cerebral ischemia . MCAo 3, 6, and 24 hours after the ischemic area leptomeningeal microvascular performance for high- frequency , low - amplitude motion , accompanied by a decrease in flow rate . Disorders of the movement of the blood vessels self-discipline , seriously affect accepted the compensatory blood flow in the ischemic area is a timely and effective manner . The frequency of vasomotor acupuncture group 3,6 hours was significantly lower than the model group , but higher than the normal group ; amplitude was significantly higher than the model group , the blood flow faster . Vascular vasomotion active , effectively \24 hours, the frequency, amplitude, have near normal levels. Described above acupuncture can timely and effective corrective the MCAo cerebral vascular disorders of the self - regulatory movement , improving cerebral microcirculation perfusion .
