本文研究恒定磁场对生物电(脑电、胃肠电、心电)活动规律的影响。看出磁场生物效应具有阈值、滞后和驰豫效应。说明在我国目前磁场疗法使用的中等磁场强度范围内,采用部位(或穴位)短时间暴磁的方法,在生物体处于正常机能状态时,磁场对生物体的作用,一般不会造成病理性变化;而当生物体处在病理状态时,磁场对生物体的作用表现出“双相”调节作用。

In 10 anesthetized adult dogs exposed to acute progressive hypoxia,changesof cardiac mechanics,as expressed by the“cardiac force loop”and cardiac conduc-tivity and excitability revealed by ECG changes,were observed.Myocardiallactate concentrations were also determined under similar experimental conditions.In early hypoxia,an enlargement in“cardiac force loop”(FLo)and a decreasein“cardiac force efficiency”(SV/FLo)were found,ECG did not show significantchanges.At the earlystage of cardiac pump failure,when FLo shrinked and SV/FLoincreased,some marked changes in the ventricular repolarization occurred,i.e.,elevated ST_Ⅱ segment and increased amplitude of T wave.Heart rate decreasedsignificantly at this stage.Arrhythmia appeared during marked shrinkage in FLo.When severe hypoxialed to FLo shrinkage,the myocardial lactate concentration was much higher thanthat of the control(P<0.05).The results of the present investigation indicate that the changes of cardiacmechanics occur earlier in the course of progressive hypoxia.Thus in assessingacute hypoxia tolerance of the heart,mechanical events offer much more sensitiveparameters than the electrical activity does.

用“心力环”表达心泵的“力效应”,以侧位肢体导联心电图来检测心脏传导系统的反应,在10条麻醉开胸狗上,观察了急性低氧条件下心泵的力学变化和心电活动演变过程的联系。在急性低氧早期,“心力环”即开始增大和“心力效率”(SV/FL_o)降低时,心电传导时间和心室复极化过程均没有明显改变(P>0.05)。直到以“心力环”环体减小及“心力效率”增加为特征的心泵衰竭出现时,才呈现心室复极化过程的明显缺氧性改变:ST_(Ⅱ)段抬高(P<0.05),T_(Ⅱ)波振幅显著增加(P<0.01);并伴以心率明显地降低(P<0.05)。在10条狗中有4条发生室性早搏或室颤等明显心率紊乱,它们均出现于“心力环”环体显著减小的严重泵衰竭时。另有8条狗在相似的实验条件下的结果表明,心泵衰竭时心肌乳酸含量明显高于对照组(P<0.05)。本研究结果提示,心泵“力效应”变化在急性低氧过程中发生得较早。这样,在评价心泵对急性低氧的耐受性上,心泵“力效应”比心脏电活动更为敏感。

Effect of applied high-voltage electrostatic field on the electrocard- iac activity of albino mice was studied on 30 healthy experimental ani- mals,the amplitude of 4350 R-waves in the ECG from 290 experiments were measured. The result of statistical processing of the data shows that the amplitude of R-waves obviously decreased during a short time from the begining of the effect of electrostatic field and obviously inc- reased during a short time after the end of the effect of the electrosta- tic field.The results of the experiments had proved that applied high- voltage electrostatic field can really affect the electrocardiac activity of the experimental animals.
