观察

It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can preindustrial observe of preindustrial societies that still exist a detailed learning of plants and their properties must be extremely ancient.

At the observation phase of the colsed peripheral nerve injury,we can observe the conduct function of the nerve by apply the pulsative electric stimulation.It provide scientific basis for the selection of the indication of the surgical treatment.

在闭合性神经损伤的观察阶段，应用电刺激治疗，可观察神经的传导功能，为手术适应证的选择和预后判断提供了依据。

AMs that collected, pured and cultured with contine method were stimulated by LPS of different concentration(0μg/ml,0.01μg/ml,0.1μg/ml,1μg/ml,10μg/ml) for 60min or by 1μg/ml LPS for different time stage (0min,5min,15min,30min,60min,120min) to observe the dynamic change of NF-кB intranuclear level and NO production, from which the best concentration and time point of LPS stimulation were selected. In the study, all AMs were divided into 4 groups: control group, group stimulated with LPS, group interrupted by Cal C and group inhibited by PDTC. The following parameters were measured: NF-кB level in nuclear protein extraction of AMs detected with sandwich ELISA, Inter-nuclear transposition of NF-кB observed with immunocytochemistry staining, NO content in cell culture medium quantitied with nitric acid reductase assay, Morphologic change of AMs in apoptosis observed with acridine orange staining and fragmentation at genome DNA of AMs detected with apoptotic electrophoresis assay.
