STUDY ON PROTECTIVE ACTION OF ELECTROACUPUNCTURE ON INJURY OF NEURONS IN RATS OF FOCAL ISCHEMIA BY MICROSCOPY AND ELECTRON MICROSCOPY

摘要

In rats of focal cerebal ischemia induced by occluding middle cerebral artery, therapeu- tic actions of electroacupuncture(EA) on injury of neurons were observed by microscopy and electron microscopy. As a results, 1. Each dimension of three-dimensional space in the cerebral infarct area in the EA group was smaller than that in the ischemic group; 2. It was found by microscopy that in the ischemic group, the cerebral infarct area was significantly larger than that in the EA group, some reaching in depth to the basal ganglion, with exfoliation of cerebral cortical infarct, most occurring sheet hemorrhagic focus, more leukocyte, mononuclear leukocyte and lymphocyte infiltration, capil- lary congestion and capillarectasia.
