Adenosine was used as the raw material, dissolved in triethyl phosphate and then esterified with thiophosphoryl chloride under 0~5℃ for 8h without water and oxgen, in alkaline condition provided by 2,6-dimethylpyridine, introducing thiophosphoryl ester to adenosine.Then superfluous triethylamine was added and reacted under 5℃ for 1h to synthesize rough 5'-AMPS.The unpurified product was appled to a DEAE Sephadex A-25 column and eluted with triethylammonium bicarbonate.

用腺苷为起始原料，溶解于磷酸三乙脂中后，在无水无氧环境中及2，6-二甲基吡啶提供的碱性条件下与三氯硫磷以0~5℃下发生酯化反应8h，将硫代磷酸酯引入腺苷，然后再与过量三乙胺在5℃下反应1h，合成粗产品，再用碳酸氢三乙胺作洗脱液，过DEAE Sephadex A-25凝胶柱纯化。

Sequences for each individual were assembled and edited using ESEE 3 0 s. A distance matrix was computed using program DNADIST of PHYLIP(3 57). Unrooted maximum likelihood trees were calculated from program FITCH.Results The amplified CO1 gene of the snail was a fragment of 638 bp in length.

OECs were cultured in the olfactory bulb of newborn Wistar rat. OECs suspension was infused into the lateral cerebral ventriculus of EAE rats, and the saline with the same quantity was infused in pseudo-operation group. Afterwards, motor-function grade, histo-pathological change and expression of apoptosis of neuron were observed.

培养、纯化OECs后，移植组将OECs悬液注入EAE大鼠的侧脑室；假手术组按以上方法注入等量生理盐水；观察二组大鼠运动功能评分、组织病理学变化以及神经元细胞凋亡表达情况。
