  硒中毒
    No cases of selenosis had been diagnosed among 349 adult inhabitants as the blood-Se level was below 1.02μg/ml. Furthermore, the minimum blood-Se level to cause persistent finger-nail symptoms among 5 susceptible cases was 1.054μg/ml ( daily Se intake 910μg).

  selenosis
It is proposed that this selenosis area coincides with Mo, F and V toxicity based on their higher concentrations in rocks, soils and plants.
      
The revegetated soil derived from bone coal and V-Mo ore dumps with excess Se, Mo, V and F concentrations in this ecosystem might have been essentially responsible for selenosis incidence of Shuang'an site in Ziyang County, Shaanxi Province.
      
In order to investigate the relationships between Se and other mineral elements and selenosis, bone coals, V-Mo ores, rocks, soils and plants were sampled from each site.
      
The Shuang'an site is the most serious selenosis site in Ziyang County, Shaanxi Province, which was the second selenosis site in China.
      
Some selenium values were high enough to suggest the possibility of selenosis in sheep.

Endemic selenosis in animals was believed to have been reported first in 1295 by Marco Polo in Western China,but conclusive evidence had not yet been ob tained in that region. An etiological investigation on this disease in human being was made in Enshi Region,Hubei Province.Results showed that selenium contents in blood and hair of residents in endemic area were far higher than those in nearby nonaffected area, endemic area of Keshan disease and Beijing.

Endemic selenosis in animals was believed to have been reported first in 1295 by Marco Polo in Western China,but conclusive evidence had not yet been ob tained in that region. An etiological investigation on this disease in human being was made in Enshi Region,Hubei Province.Results showed that selenium contents in blood and hair of residents in endemic area were far higher than those in nearby nonaffected area, endemic area of Keshan disease and Beijing. Stony coal was proved to be the source of selenium, of which the highest content was 84,000 ppm. The maximal blood selenium level was 7.5 ppm and that of corn and green turnip were 44 and 890 ppm respectively. The average selenium intakes of residents in endemic and nearby nonendemic areas amounted to 5 and 0.75 mg/day respectively. Signs of this disease were loss of hair and nails, skin lesions and nervous symptoms.

湖北恩施县历史上即有原因不明人的脱发脱甲病。作者等于1966年发现该地区为我国高硒地区,此病与硒中毒密切相关。居民发及血中平均含硒量分别为32.2及3.18ppm,相当于克山病地区的1,000及400倍。玉米中最高值达44ppm,约为后者的5,000倍。蔬菜中萝卜叶含量达891ppm。硒的来源为石煤,最高值达84,000ppm。临近中毒地区,居民每日硒摄入量达750μg,约为委内瑞拉报告值的两倍。

The selenium(Se)contents of tea samples from normal, higher and chronic selenosis areas were 0.085,0.206 and 4.027 ppm respectively. The average rates of selenium soaked out from samples of corresponding areas in boiled water were 20.2, 20.8 and 13.5%. The relative distributions of Se~(6+), Se~(4+) and below Se~(4+) in soaking water were observed to be 61.4, 13.8 and 24.8% in samples from normal selenium area, 59.5, 11.3 and 29.2% in samples from higher selenium area and 36.89 9.5 and 53.7 in samples from...

The selenium(Se)contents of tea samples from normal, higher and chronic selenosis areas were 0.085,0.206 and 4.027 ppm respectively. The average rates of selenium soaked out from samples of corresponding areas in boiled water were 20.2, 20.8 and 13.5%. The relative distributions of Se~(6+), Se~(4+) and below Se~(4+) in soaking water were observed to be 61.4, 13.8 and 24.8% in samples from normal selenium area, 59.5, 11.3 and 29.2% in samples from higher selenium area and 36.89 9.5 and 53.7 in samples from chronic selenosis area.Compared with the consumption of other foods, the influence of drinking tea on the daily selenium intake of local population is insignificant However, if the tea grown in chronic selenosis area is brought into low selenium area,it may be of certain significance for the improvement of selenium status of the local population.

本文分析了正常地区、较高硒水平地区和慢性硒中毒地区的28份茶叶样品中硒的含量,并对其在水中溶解度、存在形式以及对硒摄入量的影响进行了研究。三个地区的茶叶样品中总硒含量分别为0.085±0.030,0.206±0.186和4.027±3.033ppm。茶叶中硒的浸出率分别为20.2%,20.8%和13.5%;范围分别为11.9~30.1%,14.2~24.4%和10.0~16.9%。浸出茶水中硒的存在形式,主要有无机Se~(6+),Se~(4+)和Se~(4+)以下硒,在正常地区分别占61.4±12.2%,13.8±7.7%和24.8±14.9%,较高硒水平地区分别占59.5±18.7%,11.3±9.0%和29.2±26.4%;慢性硒中毒地区分别为36.8±8.4%,9.5±3.5%和53.7±11.3%。与当地居民的其它食物的进食量相比,饮茶水对每日硒摄入量的影响甚微。如果把慢性硒中毒地区所产的茶叶转运到低硒地区,似有一定意义。

No cases of selenosis had been diagnosed among 349 adult inhabitants as the blood-Se level was below 1.02μg/ml. Furthermore, the minimum blood-Se level to cause persistent finger-nail symptoms among 5 susceptible cases was 1.054μg/ml ( daily Se intake 910μg). Biochemical parameters indicate that cases of delay blood prothrombin time distinctly increases as blood-Se level increases to beyond 1μg/ml (daily Se intake 850μg). In addition ,plasma-Se to erythrocyte-Se ratio decreases to around 1/3 to 1/4 of...

No cases of selenosis had been diagnosed among 349 adult inhabitants as the blood-Se level was below 1.02μg/ml. Furthermore, the minimum blood-Se level to cause persistent finger-nail symptoms among 5 susceptible cases was 1.054μg/ml ( daily Se intake 910μg). Biochemical parameters indicate that cases of delay blood prothrombin time distinctly increases as blood-Se level increases to beyond 1μg/ml (daily Se intake 850μg). In addition ,plasma-Se to erythrocyte-Se ratio decreases to around 1/3 to 1/4 of that in low blood-Se state as blood-Se level increases to approach 0.9μg/ml(daily Se intake 750μg).Above results indicate the maximum safe margin of daily Se intake should be at a range of 750-850μg. When individual variation is taken into consideration, a maximum daily safe intake of Se is 400μg as a safety factor of 2.0 is applied. For seleniferous area,however, a safety factor 1.3 is applied as other influence factors such as adaptation and environmental antagonistic elements are considered, and the maximum daily safe intake is around 550μg.

体检349名成年居民结果,发现血硒水平在1.02μg/ml以下者无硒中毒病人,又5名指甲变形长期不能恢复正常者,他们中间最低血浓度为1.054μg/ml(硒日摄入量910μg)。生化检查结果发现当血硒浓度上升到1μg/ml(硒日摄入量850μg)时,凝血酶原时间延长的病例显著上升;此外,在血硒浓度接近0.9μg/ml(硒日摄入量743μg)时,血浆硒/红血球硒的比值下降至低血硒状态时的1/3至1/4。据上述结果,界限日硒摄入量应在750~850μg范围内。考虑到个体差异,建议用2.0作为安全因子,即最高安全摄入量为400μg。又考虑我国高硒区的某些具体情况如居民适应性及环境中某些拮抗元素的存在等,建议在高硒区用1.3作为安全因子,即最高安全摄入量约为每日550μg。
