The search for non-invasive methods to evaluate Cardiovascular function recently has received much allention.Kubicek and co-workers have proposed a method using changes in thoracic impedance lok calculate cardiac output which has been termed "impedance cardiograph" AS this method allows to observed hemodynamics noninvasively and continuously, it has many clinical applications.This review will describe its fundamental principal and progress in clinical applications in clu-ding the measurement of cardiac output,the early detection of pulmonary oedema, the evaluation of pulmonary hemodynamics and the measurement of many other parameters of cardiac function using the firstd erivative of the thoraclc impedce.

近年来人们逐渐认识到心阻抗血流图包含着许多有关心脏机械活动的信息,对其研究及应用由测心输出量发展到从该图测取多种心功能指标,并进而探讨不同条件下心功能改变,及各种心脏病时的波形特征。虽然本法在理论上还有许多地方尚未阐明,然而实践证明该图可提供心脏作功、心肌收缩性等多项心功能参数。其图形稳定,方法简便,指标可靠,是一种有前途的无创性心功能检查法。今后若能进一步阐明其理论基础,并更广泛地探索其在各种心脏疾病中的应用,与反映心脏电活动的心电图结合起来,人们就可以用非侵入性方法获得更多的心脏电—机械活动综合信息。

Dauricine (D), an akaloid, isolated from Menispermum dauricum DC., was reported to have antiarrhythmic and hypotensive effects. The effects of dauricine on the dose—effect response of isoprenaline and Ca~(2+) and the electro-mechanic activity in cat papillary muscle were studied and compared with tetrandrine and/or verapamil, propranolol and quinidine.1. Dauricine 8×10~(-5) M decreased and shifted the isoprenaline(ISO)dose—response curve to the right non-parallelly. It appears that dauricine is similar to tetrandrine...

The effects of dauricine on the dose—effect response of isoprenaline and Ca~(2+) and the electro-mechanic activity in cat papillary muscle were studied and compared with tetrandrine and/or verapamil, propranolol and quinidine.1. Dauricine 8×10~(-5) M decreased and shifted the isoprenaline(ISO)dose—response curve to the right non-parallelly. It appears that dauricine is similar to tetrandrine and verapamil, but different from propranolol in this respect.2. Dauricine, as tetrandrine and verapamil, showed dualistic action in Ca~(2+)-antagonism.3. Effect of dauricine on the electro-mechanic activity: it depressed and widened the R wave, prolonged R-T of the surface electromyogram of the papillary muscle, and its inotropic action was analogous to that of tetrandrine. It seems that dauricine possesses not only Ca-antagonistic but also "quinidine-like" action.

蝙蝠葛碱对异丙肾上腺素量—效反应的影响与戊脉安和粉防己碱相似,不同于β-受体竞争性拮抗剂心得安。对Ca~(2+)量—效反应的影响,亦与戊脉安和粉防己碱相似,表现为竞争性和非竞争性双重拮抗作用。在对猫乳头肌电—机械活动影响方面,对SEG的影响类似奎尼丁:R波降低,增宽,R-T延长;但同时显著抑制收缩力。结果说明蝙蝠葛碱可能具有“钙拮抗剂样”抗Ca~(2+)作用和“奎尼丁样’抑制Na~+内流的作用。

For obtaining better myocardial protection, the authors tried using the Chinese medicinal herb——Salviae Miltiorrhizae (SM) added in cardioplegic solution in animal experiment. 15 dogs were divided into four groups according to different composition of cardioplegic solution: Group Ⅰ——normal saline + SM, Group Ⅱ——high concentration of Calcium, Group Ⅲ——high concentration of Calcium+SM, and Group Ⅳ——low concentration of calcium+SM. All animals had their ascending aorta completely occluded for 120 minutes under...

For obtaining better myocardial protection, the authors tried using the Chinese medicinal herb——Salviae Miltiorrhizae (SM) added in cardioplegic solution in animal experiment. 15 dogs were divided into four groups according to different composition of cardioplegic solution: Group Ⅰ——normal saline + SM, Group Ⅱ——high concentration of Calcium, Group Ⅲ——high concentration of Calcium+SM, and Group Ⅳ——low concentration of calcium+SM. All animals had their ascending aorta completely occluded for 120 minutes under extracorporeal circulation. The results showed that in G-Ⅱ, after 120 minutes of ischemic cardiac arrest, signs of damage were apparent both in myocardial performance and in ultrastructure, while in the other three groups, only minimal or no signs of damage were observed. It is believed that SM has the effect of myocardial protection during ischemic cardiac arrest. The mechanism is still unknown. However, the authors speculate that SM might act as a calcium channel blocking agent.

作者观察丹参对缺血停跳心肌的保护效能。15只狗按不同成份心肌保护灌注液分四组进行体外循环,并阻断主动脉120分钟后,比较阻断前后心肌电机械活动和超微结构的变化。以高钙液(1.71克/升)灌注的动物,在心肌缺血停跳120分钟后,各项心功能指标均显著降低,尤以主动脉压、左室收缩压、每搏输出量和每分输出量(P<0.05),心肌超微结构亦出现严重的损伤改变。其余含丹参液的三组心功能和超微结构均未见严重损伤。说明丹参对缺血停跳心肌有一定的保护作用。根据实验结果推测丹参对心肌可能有类似钙通道阻滞剂作用。
