近红外脉冲激光体外照射大鼠对心肌细胞功能的影响

Zhongshan Daxue xuebao. Yixue kexue ban, 2013
【目的】 研究不同功率的脉冲激光体外照射大鼠对心肌细胞功能及心肌微循环的影响,探索脉冲激光体外照射心脏控制心肌细胞功能的可行性?【方法】用多模式脉宽调制(PWM)刺激仪的输出信号作为激光器的激励信号源,使激光器输出多种模式的等强度?脉宽可变的脉冲激光;对实验组的SD大鼠连续10 d照射心前区,30 min/d,10 d后取大鼠心肌标本,光镜下观察大鼠心肌细胞病理形态的改变及心肌毛细血管内径和数目的变化?【结果】功率为100 mW激光照射组心肌内层毛细血管的内径与对照组比较有显著性差异(P < 0.001)

TVS管在纳秒级强电磁脉冲下的冲击特性

Dianci bileiqi
针对防护器件暂态抑制二极管（TVS）在纳秒级强电磁脉冲作用下的特性响应问题。基于TVS管反向击穿理论，采用理论与实验相结合的方法，利用纳秒级强电磁脉冲发生器充当电磁脉冲源，选用1.5KE系列不同型号的TVS管在不同强度的电磁脉冲下进行实验。综合分析得出：随着不同型号器件直流击穿电压升高，器件残压的误差率由4%左右逐渐增加到16%；随着冲击电压的增加，TVS管动作时间逐渐减少，最终会在31 ns左右维持不变；TVS管在冲击电压一定的情况下，随着器件直流击穿电压的增加，TVS更易达到饱和状态 ...

GnRH和HMG脉冲给药对下丘脑性闭经患者诱发排卵的临床疗效观察

Zhongshan Daxue xuebao. Yixue kexue ban, 1991
8例下丘脑性闭经(HA)不孕者,年龄23～34岁,对克罗米酚和中医中药无效,在自动输液泵控制卜经静脉脉冲输注GnRH诱发排卵,结果2.5～6.25ug/90min剂量下2个治疗周期(23～36天)无反应,而10～20ug/90min剂量下9个治疗周期(11～23天)有7个周期发生了直径大于18mm的优势卵泡发育,4例妊娠。3个HMG脉冲治疗(4.9375～18.75U/90min,皮下)周期(14～20天)均出现了多卵泡发育。
