  hydrogen test
The children living in the slum presented a higher proportion of bacterial overgrowth when lactulose was used in the breath hydrogen test.
      
Breath hydrogen test was carried out after the administration of lactulose or glucose on two different days.
      
The aim of this study was to evaluate the breath hydrogen test in the diagnosis of small intestine bacterial overgrowth associated with asymptomatic environmental enteropathy in children living in an urban slum.
      
Breath Hydrogen Test in the Diagnosis of Environmental Enteropathy in Children Living in an Urban Slum
      
Although often used as a reference standard in the breath hydrogen test (BHT), lactulose fermentation produces more hydrogen, compared to starch, and may therefore not be ideal.

With lactose tolerance test (LTT) as acontrol, breath hydrogen test (BHT) wasused to study lactose malabsorption in 20healthy adults (group Ⅰ), 18 patients withsome abdominal symptoms but no diarrhea(group Ⅱ), and 18 patients with chronicsmall bowel diarrhea (group Ⅲ).During thetest the symptoms were closely observed.The hydrogen producing test of the fecalbacteria was performed among 11 subjects. The test showed that the incidence ofmalabsorption for 50 g lactose was 100%among the 56 subjects. There was no sig-nificant difference in ΔH, ΔBG and AIS(average index of symptoms) among thethree groups. There was significant positivecorrelation between ΔH and AIS(P<0.025). Breath hydrogen markedly increasedonly when carbohydrate which was notabsorbed passed through the distal ileumand colon, and bacteria living there hadability to produce H_2 during the process ofhydrolyzing sugar.The special H_2 curve ofthe patients with small bowel bacteriaovergrowth was also found. The diagnosis rate with BHT was96.4%, which was as accurate as with LTT.The false-negative was 3.6%. But the H_2technique can detect malabsorption of avery small fraction of an ingested load andit is a simple and noninvasive method forthe diagnosis of carbohydrate malabsorptionand small bowel bacterial overgrowth.

作者采用呼气氢含量测定(BHT)的方法,检测了56名汉族成人对50克乳糖的耐受情况,并用经典的乳糖耐量试验作对照,其中11人作了粪便细菌产氢试验,发现乳糖吸收不良的发生率为100%;BHT的诊断率为96. 4%。结果表明,BHT可以作为临床诊断乳糖吸收不良的简便有效的方法。同时对 BHT的机理进行了探讨。

Mannitol was used as a test sugar toestablish breath hydrogen test (BHT) in thedetermination of small bowel transit time(SBTT) .Following an oral administrationof 15 and 20g of mannitol, breath hydrogenincreased markedly in 41 out of 45 sobjects(91%), on average in 6.6 min after theentry of mannitol-barium suspension intothe cecum. The arriving of barium meals atcecum was best correlated with the first risesof breath hydrogen in those with a singlepeak pattern and the second rise in 10 pa-tients...

Mannitol was used as a test sugar toestablish breath hydrogen test (BHT) in thedetermination of small bowel transit time(SBTT) .Following an oral administrationof 15 and 20g of mannitol, breath hydrogenincreased markedly in 41 out of 45 sobjects(91%), on average in 6.6 min after theentry of mannitol-barium suspension intothe cecum. The arriving of barium meals atcecum was best correlated with the first risesof breath hydrogen in those with a singlepeak pattern and the second rise in 10 pa-tients of bacterial overgrowth (BOG) with adouble peak pattern respectively. This sug-gested that the SBTT should not be simplydefined as the time between the oral admin-istration of mannitol or any other unabsor-bable test sugar and the first rise of breathhydrogen, because the first rise in a BOGpatient was demonstrated to be formed byhydrogen gas produced in the small intestineother than the colon. So it is suggested thatmannitol-BHT should last 3 to 4 h in thedoterminnation of SBTT, so as to recognizethe pattern of breath hydrogen response.SBTT in 21 healthy subjects was 81.7±44.6min. In conclusion, mannitol-BHT iS reliableand accurate in measuring SBTT, and canbe widely used in Chine, because mannitolis abundant and much cheaper than lactulose,which is exclusively used as a test sugarabroad.

作者以甘露醇作试验糖建立了氢气呼吸试验测定小肠传递时间。45名对象分别服15及20g甘露醇后41名呼气中氢气含量明显升高(91%),用钡餐透视法作对照发现甘露醇进入盲肠后平均6.6分钟开始产氢。两法所测定的小肠传递时间具有高度相关性(r=0.80,P<0.001),说明本法准确、可靠。与国外采用的乳果糖相比,甘露醇具价格便宜、来源丰富等优点,适于国内推广应用。

Effect of La-rich ere mischmetal on Al-Si alloy have been investigated. The SQH-1 hydrogen testing instrument is used to test the hydrogen removing effect of misehmetal on Al-Si alloy. The experimental results show that Y-rich misch metal has the best modifying effect, modifying effect of La-rich. Ce-rich and Nd-rich misehmetal get weak in turn. Through the experiments, we also know that all kind of mischmetals which have been used in the thesis have the removing hydrogen function, the Ce-rich mischmetal has the best removing hydrogen effect. La-rich mischmetal is better than Y-rich and Nd-rich mischmetal in removing hydrogen from Al-Si alloy.

通过添加富镧、富铈、富钇和富钕混合稀土,考察了不同混合稀土加入量、不同冷却条件及其他因素对铝硅合金变质效果和含氢量的影响。结果表明,富钇、富镧、富铈混合稀土的变质效果依次减弱,富钕无明显变质效果。富铈、富镧、富钇和富钕混合稀土都能降低铝硅合金的含氢量,其去氢作用依次递减。
