The paper discusses the quantitative determination of deuterium in deuterated trigtyeine sulfate (DTGS). The method is that hydrogen and deuterium in the samples are quantitatively oxidized to H_2O and D_2O, and that denterium in H_2O-D_2O system is determined with near-infrared spectrophotometry. The content of deuterium in this system represents deuterated degree of samples. This method can be applied not only to the determination of deuterated degree of organic crystals containing nitrogen...

有机化合物中氢的测定方法已很成熟,但其中氘的测定,至今国内未见报导。国外的报导涉及重水体系中氢、氘的测定较多,对有机化合物中氘的测定未见详细资料。为解决有机晶体材料中氘的分析,我们通过反复试验建立了燃烧——分光光度法。方法是将样品中的氢、氘定量的氧化成H_2O和D_2O,再用近红外分光光度法测定其中的氚。关于样品中干扰元素的消除以及析出水的定量收集我们分别采用无水碳酸钠和无水硫酸钠来完成。实验证明无水碳酸钠是一种较好的除氮、除硫剂而无水硫酸钠用作水的吸收剂不仅有利于水的提纯,而且使水更易集中。水经无水碳酸钠、无水硫酸钠的提纯后可完全满足光度法测定的要求。方法用于氘化的硫酸三苷酞(简称DTGS)等材料的分析,都得到了令人满意的结果。

To evaluate cerebral function of perinatal brain injury by monitoring of near infrared spectrophotometry (NIRS). Methods Oxyhemoglobin (HbO 2), deoxyhemoglobin(Hb) and total hemoglobin (tHb=HbO 2+Hb) in the brain were monitored by NIRS pre and post music stimulation (MS) on the frontal surface of brain in newborns, comparing with 34 cases of normal group. Results HbO 2, Hb tHb is remarkably increased after MS in normal group. HbO 2, tHb have no differences( P >0.05 ) and Hb were elevated significantly( P <0.05) in mild HIE patients; HbO 2, tHb were reduced [before MS:(0.07±0.44) μmol/L,(0.48±0.43)μmol/L, after MS:(-1.72±0.59)μmol/L,(-0.98±0.55)μmol/L, P <0.05]and Hb were elevated significantly( P <0.05)[before MS:(0.41±0.28)μmol/L, after MS:(0.74±0.36)μmol/L, P <0.05]in moderate HIE patients. HbO 2, Hb and tHb were reduced significantly in severe HIE patients[before MS:(0.35±0.80)μmol/L,(0.22±0.47)μmol/L,(0.57±0.98)μmol/L, after MS: (-3.24±1.37) μmol/L,(0.15±0.51)μmol/L,(-3.09±1.39)μmol/L, P <0.05]. There was a significant negative correlation between the severity of HIE and reducing amplitude of tHb (CBF) ( r=0.64, P <0.001) . Conclusions NIRS could detect Brain function of early hypoxic ischemic encepholopathy in newborns.
