建国后克山病病因研究取得了一些进展,如否定了慢性一氧化碳中毒、生物碱中毒等学说,并于六十年代提出了生物地球化学学说(重点是缺乏说)和生物病因学说,其中以贫硒病因学说占主要地位。然而克山病的确切病因至今仍未肯定,故笔者对我国克山病病情最严重的黑龙江省老病区与至今不断有新病人发生的云南楚雄等新病区(纬度相隔二十五度)进行了流行病学对比分析,以期对病因研究有所裨益。 (一)地理位置黑龙江省病区位于我国东北部北纬46—52°、东经125°—133°。病区多分布于大、小兴安岭,张广才岭,老爷岭及向松嫩平原、三江平原移行的丘陵地带或低
After the founding of Kesshan disease etiology made some progress, such as the negative of chronic carbon monoxide poisoning, alkaloid poisoning theory, and in the sixties put forward biogeochemical theory (the lack of emphasis) and biological etiology theory, in which the poor Selenium cause of the dominant theory. However, the exact etiology of Keshan disease is still uncertain. Therefore, the author conducted a review on the new ward of Heilongjiang Province with the most serious Keshan disease in our country and the new ward of Chuxiong in Yunnan Province (with a latitude of 25 degrees) Epidemiological comparative analysis, in order to benefit the study of the cause. (A) Geographic location Heilongjiang Province Ward located in northeastern China 46-52 ° north latitude, longitude 125 ° -133 °. Ward and more distributed in large and small Xinganling, Zhang Guangcai Ridge, Laoyeling and Songnen Plain, the migration of the Hilly Sanjiang Plain or low
