稀土暴露对儿童健康影响的研究进展

随着稀土的广泛开采和应用,稀土大量进入环境和食物链中,人们或高或低浓度地接触稀土的机会越来越多,不断遭受着稀土体内蓄积所带来的健康问题.儿童是国家的希望、民族的未来,正处于生长发育的关键时期,稀土暴露对儿童健康的影响一直是国内外学者研究的焦点,但目前相关总结性综述较少.本文从稀土在儿童体内的蓄积分布及其暴露引起的健康效...     

稀土暴露对人外周血单个核细胞端粒酶及细胞凋亡的影响

目的探讨稀土暴露对正常人外周血单个核细胞的端粒酶活性及细胞凋亡的影响.方法选取我国最大的离子吸附型稀土矿江西省寻乌县稀土矿区矿工(一线作业8年以上)30名健康成人为调查对象,同时选取地质结构和社会经济特征基本相同的离矿区35 km外的寻乌县另一村居民30名健康成人作为对照.运用电感耦合等离子体-质谱法对随机选取的暴露组和对照组进行血稀土含量测定.端粒酶重复扩增法和流式细胞仪检测稀土暴露和正常人群的单个核细胞端粒酶活性和细胞凋亡以及细胞周期变化.结果血稀土含量镧(La)暴露组为(1.268 5±1.070 5)μg/L,对照组(0.171 7±0.206 1)μg/L.暴露组与对照组比较La、铈(Ce)、镝(Dy)、钇(Y)、镨(Pr)、钕(Nd)、钐(Sm)、钆(Gd)、镱(Yb)具有统计学意义;暴露组的总血稀土含量与对照组相比有统计学意义.端粒酶活性检测结果阳性率暴露组为37.0%(11/30),对照组为16.7%(5/30),两组比较有统计学意义.暴露组平均年龄为(38.69±8.02)岁,对照组平均年龄为(40.45±9.02)岁,两组年龄无统计学意义.端粒酶活性与血总稀土含量有高度相关性.暴露组和对照组外周血单核细胞的凋亡率比较,没有统计学意义,但在细胞周期分析中,暴露组与对照组相比S期和G2-M期细胞明显增多.结论可观察到在暴露水平下的接触人群稀土暴露能提高外周血单个核细胞端粒酶活性,对细胞凋亡没有影响,能促进二倍体DNA的复制及蛋白质合成,使进入S期和G2/M期细胞比例增加.

 目的：研究在灵芝培养料中添加稀土元素对灵芝的菌丝生长、子实体的鲜重和干重的影响。方法：采用稀土拌料的方法。结果：稀土的浓度对灵芝菌丝的生长均有一定程度的抑制作用,抑制率在7.49％～10.96％之间;稀土浓度对灵芝的菌丝均有增白作用,洁白度随稀土浓度的增加而降低。稀土在100,150μg·g^-1时,灵芝子实体的干重和鲜重有显著增加。在50μg·g^-1时,虽灵芝子实体的鲜重有所减少,但其干重却增加2.0％。结论：稀土浓度在100～150μg·g^-1时,灵芝的产量增加显著,可供生产使用。     

Activated charcoal is as effective as fuller's earth or bentonite in paraquat poisoning

Summary In vitro investigations have shown that the adsorption capacity of activated charcoal (Kohle-Compretten, Ultracarbon, E. Merck, Darmstadt, FRG) is just as high as that of Fuller's earth (Surrey powder, Laporte Industries Ltd., Luton, GB) or Bentonite BP W.B. (Steetley Minerals Ltd., Milton Keynes, GB). Fuller's earth (Fullererde) from another manufacturer has had very poor adsorption properties and is thus not suitable for the treatment of paraquat poisoning. Animal experiments have shown that the curative effect of activated charcoal given 0.5, 1, 2, and 3 h after ingestion of 200 and 300 mg paraquat/kg body weight is equally as good or even better than that of Fuller's earth or Bentonite BP W.B.. Activated charcoal is a substitute of equal value to these mineral soils.     

In Situ Observation of Microstructural and Inclusions Evolution in High-Strength Steel Deposited Metals with Various Rare Earth Pr Contents

The evolution of austenite, acicular ferrite, upper bainite and martensite, and the nucleation of inclusions in the microstructure of high-strength steel deposited metals, was systematically investigated using three kinds of A5.28 E120C-K4 metal-cored wires with various rare earth Pr contents. Grain structure evolution in the process of high temperature, dispersoid characteristics of inclusions and the crystallographic characteristics of the microstructure were assessed. Compared with no addition of Pr₆O₁₁, adding 1%Pr₆O₁₁ resulted in refined, spheroidized and dispersed inclusions in the deposited metal, leading to an increase in the pinning forces on the grain boundary movement, promoting the formation of an ultra-fine grain structure with an average diameter of 41 μm. The inclusions in the deposited metals were Mn-Si-Pr-Al-Ti-O after Pr addition; the average size of the inclusions in the Pr-containing deposited metals was the smallest, while the number and density of inclusions was the highest. The size of effective inclusions (nucleus of acicular ferrite formation) was mainly in the range of 0.6–1.5 μm. In addition, the content of upper bainite decreased, while the percentage of acicular ferrite increased by 24% due to the increase in the number of effective inclusions in the Pr-containing deposited metals in this study. This study shows that the addition of 1% Pr₆O₁₁ is efficient in achieving fine interlaced multiphase with an ultrafine-grained structure, resulting in an enhancement of the impact toughness of the deposited metal.
