观察

If neurological goings-on in your brain are your experiences, those goings-on need not have qualities ascribable to the objects you are experiencing.

如果你认为一个科学家观察你的大脑和观察你的体验是要观察红、白、微光或球形东西，你就错了。

Officially recognized sites as well as locally-known sites could be accompanied by 'rules' for viewing, and details on the species you might see.

不论是正式被认可的观察区，或是地方性的观察区，都必须包含观察'守则'，以及可能看到的物种的细节。

The inhibiting influenza A virus effect of catechu extract was observed by means of chick-embryo culture , and the inhibitory activity of catechu extract on influenza A virus in vitro was observed by the hemagglutination inhibition test.

用狗肾传代MDCK细胞培养法观察儿茶提取物抑制甲型流感病毒的致细胞病变作用；用鸡胚培养法观察儿茶提取物抑制甲型流感病毒增生的作用；用红细胞凝集试验观察儿茶提取物体外直接抑制甲型流感病毒的作用。

4DRG was co-culture with sciatic nerve segment in 10鸖 DMEM;the axons were longer and surround the sciatic nerve segment which was regard as anew evidence for chemotropism.

结果：(1)在无血清条件下单独培养的DRG，背根神经节的轴突数目众多，外形纤细弯曲，不成束，并且施万细胞和成纤维细胞稀少，所以可以排除两者对轴突生长的影响，为观察来源于变性坐骨神经段的可溶性因子对轴突生长的作用提供了有利条件；(2)在无血清条件下DRG和变性坐骨神经段联合培养，①先单独培养DRG，4天后待神经元轴突长出，再与坐骨神经段联合培养，观察到神经元的轴突数目减少，外形挺直，部分轴突之间相互粘附成束；②变性坐骨神经段和DRG同时联合培养，神经元的轴突数目明显减少，外形粗壮，轴突之间相互粘附成束；(3)有血清条件下单独培养DRG，轴突数目较多，外形挺直，长短不一，部分神经元的轴突之间相互粘附，施万细胞和成纤维细胞数目众多，观察到的轴突生长情况受到施万细胞和成纤维细胞的直接或者间接的影响。

MethodsThe antipyretic activity of ***PS was observed in rats with high temperature induced by dried yeast and 2,4-dinitrophenol; biliary duct cannula bile at 0.5,1,1.5,2,2.5 h after intraduodenal administration in rats was collected and counted to observe the effect of ***PS on biliary secretion;the weight of cholecyst in mice was counted to observe the effect of ***PS on the cholecyst of mice;the acute toxicity test of ***PS was done with mice.
