The phenomenon of the third order intermodulation generated during multi-frequency acousto-optic diffraction and that of the second beat frequency modulation occurring during the simultaneous multi-frequency modulation are studied. A method for compensating for these spurious modulations is proposed and the wiring diagram of an important part of the power driving circuit of the acousto-optic cell is described.

本文在声光布拉格衍射的基础上,分析了声光多频同时衍射过程中出现的三阶互调制现象和多频同时调制过程中出现的二次拍频调制现象;提出了补偿这些假调制的方法;最后给出了驱动回路中的一个重要环节——多频相加网络的具体线路.

A comparison study was made in 15 normals, 14 patients with old myocardium infarction and 10 patients with angina pectoris on ventricular wall motion and ejection fraction of the first and the second beat cineventriculography after ventricular extrasystolic beat. With postextrasystolic potentiation, twenty nine of 31 hypokinetic zones, two of 17 akinetic zones improved obviouslly, and nine dyskin-etic zones did not change. It is evident from these observation that residual left ventricular contractible...

A comparison study was made in 15 normals, 14 patients with old myocardium infarction and 10 patients with angina pectoris on ventricular wall motion and ejection fraction of the first and the second beat cineventriculography after ventricular extrasystolic beat. With postextrasystolic potentiation, twenty nine of 31 hypokinetic zones, two of 17 akinetic zones improved obviouslly, and nine dyskin-etic zones did not change. It is evident from these observation that residual left ventricular contractible function and reversible ventricular wall motion abnormalities can be detected in patients with coronary artery disease by their response to post-ventri-extrasystolic potetiation. The postextrasystolic potentiation is effective in discriminating between potentially reversible ischemic and definitely jeopardized areas, and therefore has reliable prognostic value.

The rate dependent decrease in maximum velocity of depolarization ( max ) caused by Guan fu base A (GFA) was analyzed and compared with those caused by three class I antiarrhythmic agents with different binding kinetics (mexiletine, quinidine and lorcainide) in guinea pig papillary muscles using standard microelectrode technique with computerization. In the presence of GFA, quinidine and lorcainide, trains of stimuli at various interstimulus intervas (ISI) of 200-4800 ms led to an exponential decline in...

The rate dependent decrease in maximum velocity of depolarization ( max ) caused by Guan fu base A (GFA) was analyzed and compared with those caused by three class I antiarrhythmic agents with different binding kinetics (mexiletine, quinidine and lorcainide) in guinea pig papillary muscles using standard microelectrode technique with computerization. In the presence of GFA, quinidine and lorcainide, trains of stimuli at various interstimulus intervas (ISI) of 200-4800 ms led to an exponential decline in max to a new steady state level (rate dependent block, RDB). The RDB was augmented at higher stimulation frequencies and at higher drug concentrations. The onset rate constants of RDB of max (at ISI of 300 ms) were 0.136, 0.165 and 0.076 per action potential for GFA (64 μmol·L 1 ), quinidine (16 μmol·L 1 ) and lorcainide (1 μmol·L 1 ), respectively giving approximately 50% decrease in max . Mexiletine exhibited the fastest response in the onset rate of RDB. max reached 64% of its final fall by the second beat of train. The time constants of the recovery of max (τ re ) from the RDB were 44.0, 18.2, 9.0 and 1.4 s, respectively in the presence of GFA (64 μmol·L 1 ), lorcainide (1 μmol·L 1 ), quinidine (16 μmol·L 1 ) and mexiletine (25 μmol·L 1 ). The time constants of recovery were independent of the drug concentration. These results suggest that GFA may be a sodium channel blocker with slow kinetics.

应用标准微电极技术,研究了关附甲素对豚鼠右心室乳头肌动作电位最大除极速率(Vmax)的频率依赖性抑制作用(RDB),并与美西律,奎尼丁,劳卡尼进行了比较.在相同刺激间隔(300ms),产生50%左右RDB的药物浓度下,美西律的RDB开始最快,其第2个Vmax所产生的抑制已占RDB的64%,奎尼丁,劳卡尼和关附甲素的RDB开始速率常数分别为每个动作电位0.165,0.076和0.136.美西律,奎尼丁,劳卡尼和关附甲素产生RDB的恢复时间常数分别为1.4,9.0,18.2和44.0s,而且它们的恢复时间常数是不依赖于药物浓度而变化的,结果提示,关附甲素是一个慢动力学钠通道阻滞剂.
