In normal group and sham lesion group, BDA positive neurons were distributed symmetrically in the pyramid cells of sensorimotor cortex, and BDA positive fibers of pyramid cells passed through the cerebral cortex, internal capsule, cerebral peduncle of midbrain, basilar portion of pons to the pyramid of medulla oblongata. At the lower part of the medulla oblongata, most of the BDA positive fibers passed through the pyramidal decussation to the contralateral side, continously descended at the ventral part of posterior funiculus just dorsal to the posterior gray commissure and ended at sacral spinal segments.

Every group has 3 rabbits. 2 The animal model of right iliac artery stenosis was made by the method of Clowes balloon dilation. The balloon was filled with 32P liquid that act as the radiation source in the test groups. While in the control groups the balloon was filled with saline. 3 Pathology analysis was performed on the lesion sample at different observing time point. Immunohistochemistry and electron microscope analysis were also performed on the control group and the 18Gy irradiation test group. Results: 1 Pathology analysis: On the 3rd day after PTA, a few proliferating SMCs can be seen on the internal elastic lamina in the control group. While in the 18Gy irradiation test group, no proliferating SMCs can be found. On the 1 Oth day after PTA, lots of proliferating SMCs can be seen on the vascular intima in the control group; stenosis of the vascular lumen also occurred.
