针刺百会穴对急性脑血肿大鼠局部脑血流量的影响

目的　观测急性脑血肿大鼠局部脑血流量的改变及头穴针刺后局部脑血流量和神经功能症状的变化。方法　应用L S-III型组织血流测定仪 ,选用临床上治疗脑出血常用的“百会”穴。结果　实验大鼠造模组与正常组及假手术组对比不同时刻局部脑血流量均明显下降 ( P<0 .0 1) ,而造模组与针刺组对比即刻局部脑血流量无显著性差异 ,而在 1h,4h局部脑血流量有显著性差异 ( P<0 .0 1)。另外造模组与针刺组对比神经功能症状在 1h有显著性差异 ( P<0 .0 1) ,经相关分析可见 1h局部脑血流量与神经功能症状存在负相关关系。结论　急性脑血肿大鼠局部脑血流量明显下降 ,经百会针刺后局部脑血流量的下降得到有效的改善 ,神经功能症状也得以不同程度的恢复

Effects of Needling Baihui (GV 20) on Local Cerebral Blood Flow in Rats of Acute Cerebral Hematoma

Objective To observe the changes of local cerebral blood flow and symptoms concerning nerve function in rats suffering from acute cerebral hematoma before and after treatment.Methods LS-III type blood-flow detector was used to measure the blood flow, and acupoint Baihui (GV 20), a common point for acute cerebral hemorrhage, was needled.Results The local blood flow in the brain in different times in modeling group diminished more obviously in comparison with those in normal group and sham group (P<0.01); the immediate flow in the modeling group is similar to that in acupuncture group, but it is different during the 1st and 4th hours between the two groups (P<0.01); there was a significant difference in the neurological symptoms during the 1st hour between modeling and acupuncture groups (P<0.01), with a negative correlation between the local blood flow and symptoms during the 1st hour.Conclusions Local cerebral blood flow diminishes remarkably in rats of acute cerebral hematoma; after acupuncture on GV 20, the diminishment is relieved effectively, and the symptoms concerning neurological function improve to different ranges.
