以前我们曾有报导过,克山病病区膳食组成不同,患病率有明显差异。为进一步探讨膳食因素和克山病发病的关系,一九六五年一月我们在德都县兴隆公社重病屯星火三、七队进行了改善膳食对克山病予防效果的实验观察。对照点(负对照点)是在其北边二华里的星火四队,克山病病情与三、七队相近,未加膳食改善措施。位于三、七队西南相距约三华里的花园农场一分场,农业工人户作人群对照点(正对照点)。三、七队、四队和一分场同座落在横贯东西丘陵地带的漫岗上,地势、气候、土壤等自然条件方面无大差别,均属克山病病区范围内。详见图1。
We have previously reported that Keshan disease ward different diet composition, the prevalence was significantly different. In order to further explore the relationship between dietary factors and Keshan disease, in January 1965, we conducted experimental observations on the prevention of Keshan disease by improving the diet on Keshan’s disease in teams 3 and 7 of Xingtun Commune, Xinglong Commune, Takdu County. The control point (negative control point) was the Spark IV Team in Erhuali in the north of it. The condition of Keshan Disease was similar to that of the third and seventh teams and no dietary improvement measures were taken. Located in three or seven teams in the southwest about three years away from the garden farms in a field, agricultural workers households crowd control point (positive control point). Third, seven teams, four teams and a field with the seat located in the rolling hills east and west hills, terrain, climate, soil and other natural conditions are not different, are Keshan disease within the scope of. See Figure 1 for details.
