When chloral hydrate & sodium stibogluco- nate were given in suitable doses,significant protection,especially against tartar emetic,was observed.The lethal effect of both antimony compounds was somewhat increased by amytal, alcohol and chloretone. In our experiments no definite influence was observed with the 2 central stimuiants,caffeine and strychinine,but as the number of animals used was rather small and the range of their dosage rather narrow no final conclusion can be drawn.

    1.关于吐酒石与葡萄糖酸锑 V 钠对小白鼠的致死作用,我们探索了一些中枢抑制药与兴奋药的影响。所试的抑制药有水合氯醛,溴化钾,溴化钠,溴化钙,酒精,安眠妥与三氯叔丁醇七种。兴奋药有苯甲酸钠咖啡硷与士的宁二种,以及溴咖合剂。2.在所试的药物中,水合氯醛与溴化物在适当剂量时,对于二种锑剂尤其是吐酒石中毒呈现比较显著的保护作用。安眠妥,酒精与三氯叔丁醇的数种剂量,似能增加锑剂的毒性。咖啡硷与士的宁在我们的实验条件下,并不表现明显的影响,但因所用动物数较少,剂量范围较窄,难于作出结论。

    A new method has been described in this paper for simplifying the anlysis of the liquid phase in salt-water equilibrium systems. According to this method,in a three component system of two salts and water, when the liquid phase is in equilibrium with a solid phase of definite composition such as a salt, or a salt hydrate,etc,only one component has to be determined by analysis,the other two can then be calculated. This is accomplished by first making a solution of water and one salt with definite ratio,...

    A new method has been described in this paper for simplifying the anlysis of the liquid phase in salt-water equilibrium systems. According to this method,in a three component system of two salts and water, when the liquid phase is in equilibrium with a solid phase of definite composition such as a salt, or a salt hydrate,etc,only one component has to be determined by analysis,the other two can then be calculated. This is accomplished by first making a solution of water and one salt with definite ratio, and then let the solid phase dissolve in it. Then the problem is reduced to a solubility problem. We have discussed the limitation of applicability and conditions of ensuring accuracy, and also the possibility of extension to systems of more components.In general,the larger the number of components,the more the simplification. This method is applied to the study of the system NaCl-NaAc-H_2O. It has been found to be particular by seutable,as the analysis of Na~+ or Ac~- ions is difficult.

    本文考虑了一个简化盐水体系液相成分分析的方法。用这个方法,在二盐和水的三组分体系中,只要和液相平衡的固相是一个定组成的化合物,例如纯盐,盐的某水合物等,都只要分析液相中一个组分就可以算出另外一个组分和水的含量。所以能够如此做,是因为我们可以把三组分体系中的二个组分先用固定比例配成液体,而得与液相平衡的固定出它的溶解度就行了。本文也讨论了这样做法的限制,准确度和它是否可以推广到多元体系。一般说来,组分愈多,也就愈可简化。应用这个方法求研究NaCl-NaAc-H_2O的体系是适宜的,特别是还没有好的分析方法来定Na~+及Ac~-。在本文中,只要分析Cl~-离子。本文求出NaCl-NaAc-H_2O在20℃时的相图。
