为了探讨克山病的致病因素，利用薄层色谱（ＴＬＣ）和高效液相色谱（ＨＰＬＣ）法测定了四川、云南省克山病病区和北京市非病区稻谷中串珠镰刀菌素（ＭＦ）的含量，共计１２３份样品。病区８３份中，阳性率为８．８％，阳性样品中ＭＦ的含量范围为７３．５～２６５．３μｇ／ｋｇ；非病区４０份中，阳性率为２．５％，ＭＦ含量为１７９．５μｇ／ｋｇ。用ＨＰＬＣ法测定了黑龙江、吉林省克山病病区以及四川省、北京市非病区等地区玉米中的ＭＦ含量，共测定样品１０４份。病区４３份中，阳性率为８１．４％，阳性样品含量范围为５２．３～１１１６．０μｇ／ｋｇ；非病区６１份中，阳性率为９．７％，ＭＦ含量范围为７３．３～１０８２．１μｇ／ｋｇ。从以上测定结果分析，病区和非病区粮食样品中ＭＦ阳性率差异显著，但阳性样品的平均含毒水平差异无显著性；而不同粮食品种之间ＭＦ污染的差别远较不同地区（病区与非病区）之间的差别大。
In order to explore the pathogenic factors of Keshan disease, the contents of fusarium moniliforme in rice from Keshan disease in Sichuan Province and Yunnan Province and non-diseased rice in Beijing were measured by TLC and HPLC. MF) content, a total of 123 samples. The positive rate of MF in positive samples was 73.5 ~ 265.3μg / kg in 83 samples of ward, while the positive rate was 2.5% in 40 samples of non-infected samples. The MF content was 179.5 μg / kg. The contents of MF in Keshan disease in Heilongjiang and Jilin Province, Keshan disease in Jilin Province and non-ward in Beijing and Beijing were determined by HPLC. A total of 104 samples were determined. In 43 cases of ward, the positive rate was 81.4%, the positive sample range was 52.3 ~ 1116.0μg / kg; in non-disease area 61, the positive rate was 9.7% and the MF content range was 73%. 3 ~ 1082.1μg / kg. From the above results, there was significant difference in the positive rate of MF among the ward and non-ward foodstuff samples, but there was no significant difference between the average level of MF of positive samples and the difference of MF pollination between different foodstuffs District and non-ward) the difference between the big.
