Three kinds of small molecular copper and zinc superoxide dismutase mimics were synthesized with N, N-bis (benzimidazol-2-ylmethyl) amine (N3), N, N-bis (benzimidazol-2-ylmethyl) methylamine(MN3) and N,N-bis (benzimidazol-2-ylmethyl) benzylamine(BN3) as ligands. The com-plexes were characterized by UV, IR and element analysis and the structures were proposed.

In the most caudal extent of the striatum, there was also a dense band of CGRP-positive fibers in the lateral border of the caudate putamen and the direction of the fibers was also dorsoventral. There are some transverse CGRP-positive fibers connecting the MrD and Cpu.

CGRP免疫阳性纤维分布越靠纹状体尾，则纤维越密集，且阳性带越宽；（2）在纹状体的最尾侧，除边缘区外，尾壳核的外侧缘也出现一条致密的阳性纤维带，与边缘区走向一致。

The results show that, by the way of optimizing preparation condition, the spherical zirconia powders with suitable particle size distribution are prepared using chemical precipitation method. Using heterogeneous chemical precipitation coating technique, the sph, erical nickel coated zirconia powders are prepared and the heterogeneous nucleation can be done on the surface of spherical zirconia powders. The thickness of coated layer, homogeneous degree and crack of surface can be controlled by the way of controlling powder concentration, adding rate of reactants feeding and adding surface active agent.
