改良萃取法制备托细胞神经支架的去髓鞘效果评价

Zhongshan Daxue xuebao. Yixue kexue ban, 2012
【目的】 评价改良化学方法制备脱细胞神经支架的去髓鞘与脱细胞效果。【方法】 12只成年SD大鼠(230~280g),取双侧坐骨神经,随机分为3组,每组8例,分别采用不同的处理方法。正常对照组:不作任何处理;Hudson组:采用Triton X-200、磺基三甲铵乙内酯-10(SB-10)、磺基三甲铵乙内酯-16(SB-16)处理;改良组:采用Triton X-200、SB-10、SB-16联合脱氧胆酸钠(SDC)及过氧乙酸(PAA)处理,处理后行HE染色、甲苯胺蓝染色及透射电镜检查,观察脱细胞 ...

放射损伤对外源骨髓间充质干细胞迁徙定植的影响

Zhongshan Daxue xuebao. Yixue kexue ban, 2008
【目的】 研究机体中枢神经系统受放射损伤时骨髓间充质干细胞(MSCs)的迁徙定植特性的改变,从而为应用MSCs治疗中枢神经系统放射损伤提供理论和实验依据? 【方法】用8周龄SD大鼠接受22GyX线照射制作枢神经系统放射损伤模型;从GFP鼠抽取骨髓,分离和扩增MSCs?中枢神经系统受放射损伤的SD大鼠4个月后予静脉输注GFP-MSCs?于移植后几个时间点取脑?骨髓?肝?脾等做冰冻切片,用双光子共聚焦红外脉冲激光显微镜检测GFP-MSCs?

大鼠Parv中间神经元形态学特征及其在纹状体 分布规律的探察

Zhongshan Daxue xuebao. Yixue kexue ban, 2010
【目的】 纹状体Parv中间神经元被认为是连接纹状体传入和传出神经元之间的枢纽65377;本实验旨在观察证实纹状体Parv神经元胞体65380;树突和轴突的形态学特征和在纹状体的分布及其与纹状体不同区域之间的关系65377; 【方法】 对成年雄性SD大鼠常规灌注固定和取脑;半导体冰冻切片之后进行免疫组化PAP方法单标记和双标记;光镜观察阳性神经元的形态并进行计数和计算其百分比;应用SPSS软件统计处理65377; 【结果】 Parv阳性神经元在纹状体呈现散在不均匀分布,在纹状体背外侧区的分布多于其它区域(
