多轴突细胞

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。

In the suboesophageal ganglion, 5-HT/TPH-likeimmunoreactive neurons (ca.15) mainly distributed in the lateral and ventro-lateral area, withprocesses projecting into the suboesophageal ganglion neuropil.

咽下神经节处5-HT/TPH阳性神经元数目相对较多，每侧大约有15个，主要分布于髓区侧细胞体层和腹侧细胞体层，轴突投射进入咽下神经节。

Only 1 single 5-HT/TPH-like immunoreactive interneuron was localized near the dorsal antennal lobe, contributing to most immunoreactivity in the antennal lobe.

咽下神经节处5-HT/TPH阳性神经元数目相对较多，每侧大约有15个，主要分布于髓区侧细胞体层和腹侧细胞体层，轴突投射进入咽下神经节。

The efferent projections of hypothalamic and brain stem nucleuses to nucleus dorsalis nervi vagi were studied by means of the retrograde axonal transport of HRP technique in cats.

本文用HRP轴突逆行输送法，对猫下丘脑和脑干一些核向迷走神经背核的传出投射进行了研究。将HRP注射至迷走神经背核后，较多的标记细胞见于同侧下丘脑的室旁核、背内侧核以及中脑的中央灰质和被盖腹内侧区。

It"s vegetal mycelia were colorless, smooth, 1.2μm～3.0μm crude, manyconidiogenous cells born on vegetal mycelia, sometimes as many as a dozen,a very small number were single. The base of conidiogenous cell wasenlarged and many of them were bottle-shaped or spherical. The upper ofconidiogenous cell extended into a conidiogenous axis of 1μm wide and 14μm length which was the knee-bending ("Z like bending), there were small pectinae on the axis, conidium located on the small pectina.

营养菌丝无色，光滑，有隔，粗1.0μm～3.0μm，产孢细胞常浓密簇生于菌丝或泡囊上，有时可多达十几个，极少数单生，产孢细胞基部膨大，多为瓶形，近球形，颈部明显延长成粗1μm，最长达14μm的产孢轴，呈膝状弯曲，轴上具小齿突，分生孢子位于小齿突上。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
