Objective To explore the effect of high serum concentration of bile acids on energy metabolism of liver.Methods Bile acids were continously infused into the Wistar rats to simulate the serum concentration change of patients with obsturctive jaundice.Serum bile acids concentration,arterial blood ketone body ratio and energy charge of liver were determined.Results Aterial blood ketone body ratio and energy charge of liver decreased with the increase of serum bile acids concentration.Conclusion High serum concentration of bile acids plays an important role in hepatic fumction injury caused by biliary obstruction.

目的 探讨高胆汁酸血症单一因素对肝脏能量代谢的影响方法经Wistar大鼠颈内静脉持续给予外源性胆汁酸，升高其外周血清中胆汁酸浓度，模拟阻塞性黄疸患者外周血清中胆汁酸的变化规律，观察腹腔动脉血酮体比值及肝组织能荷变化，时间一周结果随外周血清中胆汁酸浓度的升高，腹腔动脉血酮体比值、肝组织能荷均呈进行性下降结论高胆汁酸血症时肝脏能量代谢受损，表明在阻塞性黄疸患者肝功能损害中高胆汁酸血症起了重要作用

The results showed that As forms in soils were mainly composed by fixed forms of As when As added at high rate and soil As for ms were mainly composed by labile As,esp.exchangable As,when As added at low rat e.The lability of soil As was improved when astragalusy was added.

结果表明，外源砷浓度高时土壤砷形态以固定态砷为主，外源砷浓度低时以活性态砷为主，尤以交换态砷为主；施入紫云英土壤砷的活性增强；土壤AEC与活性砷含量呈线性正相关。

Experimental results show the lag phase of Thiobacillus ferrooxidans was longer and bacterium density was decreased when 0.25% pulp density of metal sulfides or 1% element sulfur was added in 9K medium.

同时研究了多种因素对氧化亚铁硫杆菌生长活性的影响，发现在Fe〓氧化体系中添加0.25％固体物浓度的硫化矿物时，细菌的Fe〓氧化速度会降低，细菌生长停滞期延长，浸出液中细菌浓度减少。

The results show that the Lande factors are 2.002~2.003, which have little change, and that of coal from Zhangji coal mine are little larger than that form Baijigou coal mine. Small particle size, high oxidation temperature and long oxidation time can lead to high corventration and high line height. However, the trend of line width is dispersive.

结果表明：煤自由基因子在2.002~2.003之间，变化不大，张集矿肥煤的因子值稍大于白芨沟无烟煤；煤体粒径越小、氧化温度越高、氧化时间越长，煤自由基浓度越大；线高的变化趋势与自由基浓度变化趋势基本一致；线宽的变化趋势呈分散性。

Urthermore the redox currents of Fe 〓 increased with increasing the concentration of lanthanides and leveled off at 1. 2μM for Eu〓.

e〓的氧化还原电流随着稀土离子的浓度的增加而变大，对于Eu〓当浓度达到1.2μM时，电流不再增加。

With 20 mg/L Lanthanum nitrate treatment was best, and with 15 mg/L Lanthanum nitrate treatment was the second best.

其中以20mg/L浓度处理效果最好，其次为15mg/L浓度的处理。

The testing results suggests that the increase of H2S concentration will raise the brittleness coefficient, leading to the decrease of corrosion resistance for either X70 base metals or welding joints. Meanwhile, the results reveals that effect of H2S concentration on X70 base metals and welding joints is different: the influence of H2S concentration on welding joints'SSCC is bigger than on base metals'SSCC.

揭示了随着硫化氢浓度的增加，国产X70管线钢及其焊接接头的脆性系数增加，抗腐蚀能力减弱；硫化氢浓度对国产X70管线钢母材和焊缝的SSCC性能有着不同程度的影响：在相同的试验条件下，焊缝的脆性系数显著大于母材的脆性系数，即焊缝较母材的SSCC敏感性大。

Kala-azarpatients were examined by ELISA with three Leishmania strains antigen, the results were 901 strain with 80.92%, 801 strain with 92.25% and 951 strain with 89.92%. The result was notable difference between 901 strain and 801 strain. 334 healthy persons serum of endemic areas were tested by ELISA with three Leishmania strains antigen, the positive rates were notable differenceamong three antigens.

结果：提取的三株抗原的蛋白浓度分别为：901株1000ug/ml、801株800ug/ml、951株1000ug/ml；工作浓度均为10ug/ml；三株抗原分别检测24份肺结核病人血清，均为阴性；三株抗原分别检测60份非疫区健康人血清，801株与951株的检测结果均为阴性，901株检测出一份阳性；三株抗原分别检测131份黑热病病人血清，阳性率分别为：901株80.92%、801株92.25%、951株89.92%。801株明显高于901株。

In Cd 0.3mg/L treatment the lignification of the main roots was particularly serious.

在镉浓度0.3mg／L浓度中的凤眼莲，主根木质化程度尤为严重。

Its color became lighter. In Cd 0.3mg/L treatment the lignification of the main roots was particularly serious.

在镉浓度0.3mg／L浓度中的紫萼玉簪，主根甚至大的侧根木质化程度尤为严重。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
