【摘要】 本文报告1981—1985年对非硒防克山病轻、重病区的病情及内外环境中硒的含量进行监测。结果表明:两试点均无急型、亚急型发病,潜、慢型病人的检出率逐年减少,慢型病人五年存活率为80%,潜在型的转健率约为30%,健康人群中均有新潜在型检出。在土壤及粮食中硒的含量无明显变化;而发硒均明显提高,是由于生活水平提高,食用非病区商品粮小麦增多以及硒膳食改善发生的变化。更多还原

【Abstract】 This article reported that the monitoring for the information of Keshan diseasein heavy and light endemic areas without selenium prevention and the monito-ring for selenium status of population and environment was carried out,from 1981to 1985.The results revealed that the incidence rate of acute、subacute types Keshandisease was not found in both experimental units,the morbidity of potential andchronic types Keshan disease was decreased year by year,the five years alive rateof the chronic type patients was 80%,the recovery rate of the potential type wasabout 30%,the new potential type cases was discovered among the healthy peoplein both experimental units.Every year,the average Se contents of soil andgrains (corn,wheat,soybean) were not significant change,but the average Se contents of human hair in both experimental units were increased significantly,because the living standard of the peasants lived in both experimental unitshadraised.They had improved their meals and had eaten much commodity grains(wheat) produced in non-endemic areas.更多还原
