用光镊研究稳恒磁场对血红细胞的活性影响
南京理工大学紫金学院
2014/3/31
为了研究稳恒磁场对离体血红细胞的活性衰变产生的影响,采用非接触、无损伤的光镊技术进行了实验与分析。光镊中的高斯激光光束作用使红细胞发生形变,待细胞稳定后切断光路,得到形变血红细胞的相对形变量值,该量值大小与红细胞活性相关;对比了正常离体血液与静置于稳恒磁场中的红细胞活性衰变规律。结果表明,0.20T稳恒磁场可以提高红细胞的变形能力,增强红细胞的活性;同时加速了细胞体内能量的消耗,因离体环境没有能量...
微波辅助碱解荧光分光光度法快速测定河豚毒素含量
河豚毒素 荧光分光光度法 微波碱解
2009/10/22
建立了一种快速、简便、灵敏地测定河豚毒素的新方法。在水和异丙醇混合碱性溶液中对河豚毒素进行微波碱解，通过测定碱解产物的量来间接测定河豚毒素的含量。结果表明：C9碱的最大激发波长为380 nm，最大发射波长为496 nm，其在0.1～10 μmol·L-1的浓度范围内与荧光强度呈线性关系，相关系数r=0.999 1，检测限为0.05 μmol·L-1,比文献报道降低近20倍。该方法快速、灵敏和准确，...

脉冲电磁辐射对癌细胞的影响
2007/12/13
摘要: 通过对HeLa细胞及艾氏腹水癌细胞进行电磁脉冲处理，可以看到照射后HeLa细胞较对照组有明显变化，且变化随照射时间的增加逐步显现、加强。艾氏腹水癌细胞经脉冲电磁场照射后摄取3H-TdR的量明显高于对照组，而且照射时间不同，对3H-TdR摄取量也不等。从而为电化学治疗癌症的理论研究提供科学的依据。
