Low concentration ryanodine can mimic BDNF to induce growth cone attraction and high dose ryanodine gradient is repulsive to the growth cone.

ryanodine 可以模拟 BDNF 的吸引作用。为进一步研究 Rho GTPases 在轴突转向中的作用，我们将 Cdc42及 RhoA 的显性失活突变基因(dominant negative， DN)及组成性激活突变基因（ constitutively active， CA ）注射到爪蟾胚胎2-4细胞期的一个细胞中，使它们在胚胎神经元中表达，并观察这些突变基因对 BDNF ， LPA ， ryonodine 诱导的轴突转向的不同影响，从而推测 Rho GTPases 是否直接参与并介导轴突导向。

The structure brief introduction the dense thick liquid pump of one stud of i-1b s series is formed by four parts electromotor , shaft coupling , pump and bases motive force joining in marriage usefulness uses y s series asynchronous electromotor of three-phase the shaft coupling uses the water pump with the paw mould elasticity shaft coupling the pump by the pump shell , become hollow inside axle and universal twists joints and winds axle , stud , bush and axle seal and package places and goes out the material mouth etc and forms , and the section of stud is the oval for round and bush section , and his interior surface is the duplexing spirals faces .

结构简介 i-1b系列单螺杆浓浆泵由电动机、联轴器、泵和底座四个部分组成。配用的动力采用y系列三相异步电动机。联轴器采用水泵用爪型弹性联轴器。泵由泵壳、空心轴、万向绞接头、绕轴、螺杆、衬套、轴封装置和出料口等组成，螺杆的断面为圆形、衬套断面为椭圆形，其内表面为双螺旋面。

The movement order is that the bag-catcher of the automatic bag-giving device sucks the empty bags on the first stack through the vacuum sucker and lifts it, with the clamping jaw of the clamping tower clamping the lifted empty bag and towing it on the bag-bearing platform of the bag-giving device. The bag central locator locates the empty bag into the center. Then the empty bag held in the center is moved horizontal and sent to the position of the bag-giving manipulator through the bag-shifting pressing wheel downward and bag-shifting synchronous belt.

其动作顺序为自动上袋装置的取袋器通过真空吸盘吸住供袋架上第一垛位的空袋并提起，夹拖器夹爪将提起的空袋夹住并拖至上袋装置支座架平台上，袋子对中器把空袋对中至中央位置，移袋压轮向下和移袋同步带把压持在中间的空袋平移送至上袋机械手位置。
