title: [Morphological study on acupuncture in interfering experimental cerebral infarction in rat. I. Compensation of cerebral PIA mater artery in cerebral surface].
abstract: Occluding unilateral middle cerebral artery (MCAo) of rat, the compensatory blood vessels (CBV) within ischemic area in cerebral surface shown by cerebral perfusion and effect of acupuncture were observed dynamically. Perfusing immediately after MCAo, there was no any blood vessel in the ischemic area. In acupuncture group, the CBV had extended a lot from anastomotic network of cerebral pia mater (ACA-MCA, PCA-MCA) located in marginal zone of ischemic area 3 hs after MCAo. 6.24 and 48 hs after MCAo, the CBV increased much more than control group (non-acupuncture) P < 0.01. The experiment pointed out that there existed a serious vasospasm in the MCA system in initial stage of MCAo, which led up to decompensation in the ischemic area. The acupuncture can remit the vasospasm, and reverse the deteriorated process in early.
