Result shows that there is no significant difference in distribution of any two sections' sympathetic nerve in normal goats annulus fibrosus disci intervertebralis,there is no significant difference between the sympathetic fibers distribution of convex side and concave side in annulus fibrosus disci int ...

方法先建立山羊脊柱侧凸模型，将椎间盘纤维环分为左前、左后、右前、右后四个区，然后通过NF200常规荧光组化和乙醛酸染色来研究正常山羊、侧凸山羊、正常人和青少年特发性脊柱侧凸患者椎间盘不同部位纤维环的交感神经分布特点。

The preliminary stiochiometric analysis showed that when the enzyme metabolized EDDA, two acetyl groups were removed and ethylenediamine and two glyoxylates were produced in the presence of oxygen.

然后对该酶促反应进行了定量分析：结果显示在IDA氧化酶的作用下每代谢一分子的EDDA将生成二分子的乙醛酸及一分子的乙二胺，同时也检测到过氧化氢的生成。
