The inorganic salts of antimony, arsenic and bismuth are toxic substances, but their hard dissociated organic derivatives are less toxic and are widely used in the- rapy. Organic chelating compounds such as ethylenediaminetetraacetic acid (I) are often used as agents for detoxification of heavy metals. It appears that complexes formed by therapeutic metals and ethylenediaminetetraacetic acid would be less toxic as well and might be useful therapeutically.

The inorganic salts of antimony, arsenic and bismuth are toxic substances, but their hard dissociated organic derivatives are less toxic and are widely used in the- rapy. Organic chelating compounds such as ethylenediaminetetraacetic acid (I) are often used as agents for detoxification of heavy metals. It appears that complexes formed by therapeutic metals and ethylenediaminetetraacetic acid would be less toxic as well and might be useful therapeutically. Such compounds have been prepared in the present work. Attempts to react ethylenediaminetetraacetic acid or its mono, di or tetra-sodi- um salts with freshly precipitated antimonous oxide were not successful. The former also failed to react with potassium antimonyltartrate. Treatment of antimony trichloride on aqueous ethylenediaminetetraacetic acid, however, gave a complex, which could be recrystallized from water without hydrolysis, and which gave no precipitate with catechol or rhodizonic acid. This complex forming reaction is most favourable at a pH of about 2.5. Neutralization of the complex with various alkalis or amines afforded the corresponding potassium, sodium, lithium, ammonium, ethylenediammonium and diethylammonium salts, which are water-soluble. Neither antimony pentachloride nor arsenic trichloride gave the corresponding chelating compounds with ethylenediaminetetraacetic acid under similar conditions. A bismuth chelate was formed by interaction of bismuth basic carbonate and aqueous ethylenediaminetetraacetic acid at 80°. This sparingly soluble chelate gave water-soluble salts on treatment with sodium hydroxide or ammonia. In order to study its structure, a pseudo-ephedrine salt, m. p. 270-271° (decomp.), (α)_D~(10)=-1.28,° was prepared. Recrystallization of this salt, however, did not cause change in optical rotation. Structure II should give optical isomers. An alternative symme- trical structura was recently suggested by Japanese authors. It was shown in our previous work that stannous tin could yield potential therapeutic compounds. Attempts were therefore made to prepare a stannous chelate of ethylenediaminetetraacetic acid. Although treatment of the latter with stannous oxide did not afford a pure compound, its disodium salt and stannous chloride interacted smoothly in water and a chelate was formed. This new com- pound gave no precipitate on treatment with alkalis, oxalate or sodium thiosulphate, but it could reduce mercuric salts, and metallic tin was separated on treatment with zinc. A water-soluble diammonium salt was prepared. Oxidation of the stannous chelate of ethylenediaminetetraacetic acid by means of hydrogen peroxide afforded the corresponding stannic chelate. Since it could not be dehydrated under reduced pressure and its aqueous solution was distinctly acidic, its structure was assumed as a tetradentate ligand (Ⅲ) rather than a hexadentate one (Ⅳ). It was recently shown by Indian authors that tervalent metals did not necessarily give hexadentate ligand chelates. The stannic chelate is less stable toward alkali than the stannous compound. Preliminary pharmacological tests revealed that the sodium salt of the antimony chelate was as active as tartar emetic against schistosomiasis japonica in white mice.

Using different ways to increase the intracranial pressure (ICP) of cats, we have observed the changes in the electroencephalogram (EEG) and electrocardiogram (EKG). The results are as follows:1. When ICP is increased step by step to 30-40 mmHg the frequency of EEG increases and the amplitude is lowered. When ICP is increased to 50-70 mmHg the slow wave predominates. Finally, the cortical electric activities disappear when ICP is increased to the level of the blood pressure (BP). There exists a close correlation...

Using different ways to increase the intracranial pressure (ICP) of cats, we have observed the changes in the electroencephalogram (EEG) and electrocardiogram (EKG). The results are as follows:1. When ICP is increased step by step to 30-40 mmHg the frequency of EEG increases and the amplitude is lowered. When ICP is increased to 50-70 mmHg the slow wave predominates. Finally, the cortical electric activities disappear when ICP is increased to the level of the blood pressure (BP). There exists a close correlation between the changes of EEG and the cerebral perfusion pressure (CPP) which is the difference between the mean arterial pressure and the ICP. CPP is decreased both by increase of ICP and by decrease of BP caused by heart failure.2. When ICP is increased quickly to half level of BP no obvious change appears in EEG, if CPP is not below 70-80 mmHg. If CPP decreases with the drop of BP, there will be obvious changes in EEG which will finally develop into electric silence.3. When ICP is rapidly increased to the level approaching BP, EEG disappears within 16-17 minutes.4. An increase in ICP will lower the heart rhythm and cause changes in BP and EKG. The changes of EKG will take place with normal or abnormal BP. This phenomenon might be related to the excitability of the cardiovascular centre.

在猫上用不同方式升高颅内压,观察脑电图和心电图的变化,结果表明: 1.阶梯性升高颅内压至30—40毫米汞柱时,脑电波频率加快,振幅降低。颅内压升高至50—70毫米汞柱时,以慢波占优势。当颅内压升高接近血压水平时,脑电活动消失。脑电图的变化与脑灌注压有密切关系,除颅内高压可以引起脑灌注压下降外,心脏功能的障碍也可促使血压下降,从而致使脑灌注压降低。 2.急骤升高颅内压至血压的二分之一水平时,如脑灌注压不低于70—80毫米汞柱,脑电图上不出现明显异常。如脑灌注压因血压的下降而迅速降低时,脑电图将出现明显异常,直至脑电波消失。 3.颅内压急骤升高至血压相近水平时,脑电活动在16—17分钟时即发生消失。 4.颅内高压可以引起心率减慢、血压和心电图异常;心电图异常改变可发生在血压异常升高后,也有发生在血压正常时,这可能与心血管中枢的兴奋性改变有关。
