文题释义:
抬高身体摇摆实验:用于测量运动不对称,测量时首先用手提起大鼠的尾根部,大鼠头部悬垂距平面   5 cm左右,这时大鼠头部会向左侧或右侧旋转,向单侧旋转的角度大于10°时为计数标准,记录旋转的方向和角度,一次实验后让大鼠休息1 min,再进行下一次实验,重复实验20次,记录总的次数和方向。
尼氏体:为嗜碱性物质,又称嗜染质,光镜下呈斑块状或细粒状散在均匀分布。在一些大型的运动神经元,尼氏体大而多,宛如虎皮花纹,又称“虎斑”。电镜下,尼氏体由大量平行排列的粗面内质网和其间的游离核糖体组成。尼氏体是神经元胞体细胞质的特征性结构之一,神经元胞质另外一特征性结构为神经原纤维。
 
背景:移植入宿主体内的神经干细胞能够存活、增殖、分化为神经元和/或胶质细胞,从而促进宿主缺失功能的部分恢复。
目的:观察神经干细胞移植对脑性瘫痪大鼠的治疗作用。
方法:将24只大鼠随机分为3组:对照组,模型组和移植组,后两组脑性瘫痪模型建立后1周,移植组大鼠经颈静脉注射1 mL神经干细胞悬液(1×105个),对照组和模型组大鼠经颈静脉注射1 mL生理盐水。移植后3周,测量各组大鼠的趾距、步长和抬高身体摇摆情况,并观察各组大鼠大脑病理组织学变化。
结果与结论:①模型组大鼠的左前掌趾距和步长明显低于右前掌趾距和步长,差异有显著性意义(P < 0.05),移植组和对照组大鼠的趾距、步长均明显高于模型组,差异有显著性意义(P < 0.05);②模型组抬高身体为不对称摆动,对照组和移植组大鼠为对称摆动;③移植组和对照组大鼠的右侧大脑半球面积/左侧大脑半球面积比值明显高于模型组,差异有显著性意义(P < 0.05);④结果表明,经颈静脉移植神经干细胞可明显改善脑性瘫痪大鼠的病理损伤,并可恢复运动神经行为学功能。

Abstract:

BACKGROUND: Transplanted neural stem cells can survive, proliferate and differentiate into neurons and/or glial cells in the host, thereby promoting partial function recovery in the host.

OBJECTIVE: To study the therapeutic effects of neural stem cell transplantation on cerebral palsy rats.
METHODS: Twenty-four rats were randomly divided into three groups: control group, model group and transplantation group. Animal models of cerebral palsy were made in the latter two groups. One week after modeling, rats in the transplantation group were injected 1 mL stem cell suspension (1×105) via the jugular vein, and rats in the control and model group were given the same volume of normal saline. Toe distance, step length and elevated body swing test in rats were detected, and histopathological changes in the rat brain were observed 3 weeks after transplantation.
RESULTS AND CONCLUSION: In the model group, the toe distance and step length of the front left palm were significantly lower than those of the front right palm (P < 0.05). Compared with the model group, the toe distance and step length in the transplantation and control groups were significantly increased (P < 0.05). In the elevated body swing test, rats in the model group presented with asymmetric swing of the body, but rats in the other two groups exhibited symmetric swing of the body (P < 0.05). Additionally, the ratio of right to left hemispheric areas was significantly higher in the transplantation and control groups compared with the model group (P < 0.05). In conclusion, neural stem cell transplantation via the jugular vein can improve brain function and restore motor function in rats with cerebral palsy.
