脑血管疾病是严重危害人民健康的疾病之一

是老年人致残和死亡的主要原因。所以脑血管疾病的防治已引起国内外医学界的广泛重视

联合国世界卫生组织在75年召开了脑血管疾病防治专题学术会议。会议决定在世界范围内进行脑血管疾病防治方面的研究。根据首都地区调查表明脑血管病、心血管疾病和肿瘤

在目前是死亡率最高的三大疾病。祖国医学早在《内经》中即指出:中风之为病

如矢石之中人

骤然而至。”张仲景指出:“失风之为病

当半身不随”(《金医要略》)。说明该病发病急

临床症状明确

采用针灸治疗For studying the mechanism of therapeutic effect of acupuncture on the cerebral vascular diseases

dogs were anaesthetized with 30 mg/kg Pento- barbital sodium and ventilated by a respirator. Amimal model of cerebral infarction was set up after partial craniectomy of parietal and temporal bone

the left middle cerebral artery (MCA) was occluded. A number of blood gas indices of blood sample collected from carotid artery and supe- rior sagittal sinus were printed out directly with ABL-2 blood gasmeter. The blood samples of acupuncture group (n=12) and control group(n=13) were measured and recorded five times in this experiment respectively. Effect of acupuncture Renzhong and Hegu points on the metabolism of oxygen in cerebral were observed. The results are as follows: The difference of oxygen tension between artery and vein blood(Pa-vO_2 and oxygen absorption rate of cerebrum(A-v(Hb.1.39.SAT/A(HB.1.39.SAT) inc- reased gradually in the control group. However

Pa-vO_2 and oxygcn absor- ption rate of the cerebrum in the acupuncture group began to be reduced by acupuncture after 30 minutes. The difference of internal group and between groups by second 30 minutes of acupuncture are all remarkable (P<0.05). However

oxygen saturated degree of the blood (SAT) has not altered remarkablly both in the acupuncture group and control group. The results described above showed that Pa-vO_2 and oxygen absorption rate of the cerebrium could be reduced by acupuncture. It was suggested that the oxygen metabolism rate of the cerebral tissues might have been reduced by acupuncture.
