查询词典 axons

Through immunocytochemistry study, we found that the α3 and/or α5 subunits of nicotinic acetylcholine receptor are predominantly expressed in the oxytocinergic neurons. Our finding is quite different from the conclusion of the British scholar Dr. Mason's work in 1980s. We also found in this study that, the α3 and/or α5 subunits of N-AChR can also be expressed on the axons of oxytocinergic neurons, and these immunoreactive axons could be seen projecting to the median eminence and further to the posterior end of neurohypophysis. In the hypothalamus of the 7-day postnatal pup rats, the expression patterns of α3 and/or α5 subunits of N-AChR are similar to that in adult rats.

Cells were collected to undergo HE staining and immunocytochemistry reaction against Thy-1 to identify RGCs. Axons length of retinal neurons and RGCs were measured by microruler under microscope respectively to evaluate the neurotropic effects of B vitamins in improving the regeneration and growth of axons for retinal neurons and RGCs. Finally, we observed the reaction of retinal neurons when exposed to the insult of glucose deprivation. The neuroprotection of B vitamins were also evaluated at the same time.

对B族维生素的神经营养和保护作用的研究过程分为三个阶段，首先确定维生素B族对视网膜神经元是否有神经营养作用，并根据细胞活力找出最佳有效作用浓度；然后在接种细胞的即刻用各种维生素的最佳有效作用浓度作用于视网膜神经元，并在不同时间终止培养，收集细胞，HE染色和RGCs的免疫细胞化学染色，分别测量视网膜神经元和RGCs的轴突长度，评价维生素B族是否有促进视网膜神经元和RGCs轴突再生伸长的神经营养作用；最后，观察视网膜神经元对低糖损伤的反应，及维生素B族对受损的细胞是否有保护作用。
