| 1 | 中药甘松挥发油对HEK细胞Na_v1.5电流电压及电导电压的影响显示文摘目的应用膜片钳技术研究HEK细胞Nav1.5电流电压依赖性Na+电流失活与激活曲线,甘松挥发油对电流-电压关系(I-V),电导-电压关系(G-V)曲线的影响,以及对快Na+通道失活(H-I)的影响。方法应用膜片钳技术研究HEK细胞Nav1.5电压依赖性Na+电流失活曲线,I-V和H-I曲线。结果正常自然依赖性失活曲线向超极化移位,移动速度10 min内是4 mV。甘松挥发油能降低I-V曲线Na电流的峰电位,但不能改变其Na电位(ENa)从内流向外流的反转电位的方向。G-V曲线明显向超极化方面移动,Vg1/2=(-59.8±4.22)mV是对照自然失活曲线;Vg1/2=(-58.8±5.69)mV是10 PPM甘松挥发油;Vg1/2=(-68.0±4.36)mV是药物被洗脱后失活曲线(P<0.01,n=6)。在除去自然移动值后10 PPM甘松挥发油的Na电位失活作用明显。甘松挥发油应用前,应用10 PPM甘松挥发油以及药物洗脱后H-I曲线与自然失活曲线比较,校正自然失活因素后10 PPM甘松挥发油实际移动Vg1/2是(18.0±4.50)mV(P<0.01,n=5),洗脱40min后接近对照状态。结论甘松挥发油对I-V,G-V曲线有向超极化移位的影响。对快Na+通道有加速失活与抑制激活的作用,然而电压依赖性Na失活是可逆性的。这一作用奠定了甘松挥发油抗心律失常的作用机制。 | 葛郁芝 吴志婷 胡朗吉 Yeh Jay Z | 2009 | 时珍国医国药2009,20,1: | 13 |
| 2 | HEK细胞Nav1.5电流对甘松挥发油浓度及电压依赖性阻滞显示文摘目的:研究甘松挥发油对人肾胚胎(HEK)细胞Nav1.5电流的影响。方法:应用细胞膜片钳技术研究甘松挥发油对鼠cDNA编码组成的纯钠通道在人胚胎肾细胞(HEK)表达的Nav1.5细胞离子通道电流的影响。结果:发现甘松挥发油对Na电流的阻滞作用受挥发油浓度影响,量-效反应量呈'S'曲线型,电压钳制影响表现为膜电位越低(电位上移)阻滞作用越强。结论:甘松挥发油对钠电位有明显阻滞作用,其作用随剂量增加而增加,随膜电位降低而作用加强。提示临床可用于因心肌缺血导致膜电位降低而诱发的心律失常。 | 葛郁芝 吴志婷 张淑华 盛国太 Yeh Jay Z | 2009 | 中药药理与临床2009,25,3: | 5 |
| 3 | 甘松挥发油对大鼠心肌细胞及HEK细胞Nav1.5钠电流的影响显示文摘目的本实验应用膜片钳技术研究HEK细胞Nav1.5电流频率依赖性阻滞时间恢复过程及甘松挥发油对其影响,以及不同浓度甘松挥发油在不同电压钳位下对大鼠心肌细胞钠内向电流的影响。方法发放两次刺激脉冲,间隔从16 ms到1s,电压钳置在-80~-140 mV,观察3ppm(1:333K)浓度甘松挥发油对HEK细胞Nay1.5电流频率依赖性阻滞时间恢复过程。测定不同浓度甘松挥发油在不同钳位电压下对大鼠心肌细胞内向电流的影响。结果 (1)甘松挥发油比对照组产生电流频率依赖性阻滞时间恢复过程缓慢(对照组33.2±5.77 ms,3 ppm甘松挥发油组52.5±6.08 ms,P<0.01),钠电流抑制随刺激频率脉冲间隔时间缩短(56.50~16 ms)而阻滞加重。对照组阻滞恢复时间开始于19.5 ms,完成于36.5 ms;3 ppm甘松挥发油阻滞恢复时间开始于36.5 ms,完成于56.5 ms。(2)浓度1:20 K(相当于生药3.4 g/L)在钳位电压-100mV时无明显静息阻滞,钳位电压在-80 mV时有明显的内向电流阻滞作用;钳位电压在-100 mV,药浓度达1:1K(68 g/L)时,呈现明显的内向电流抑制。结论 (1)HEK细胞Nav1.5通道电流频率依赖性阻滞恢复与刺激频率,钳置电压高低有关,甘松挥发油能延缓电流频率依赖性阻滞恢复时间过程。(2)不同浓度的甘松挥发油对大鼠心肌细胞在不同钳位电压下对钠内流阻滞影响不同。 | 葛郁芝 盛国太 Yeh Jay Z | 2011 | 岭南心血管病杂志2011,17,S1: | 4 |
