Cook(1971)提出,在非洲玉米的耕作和食管癌发生之间的联系是清楚的。许多学者报导玉米易为镰刀菌污染,并存在有镰刀菌毒素及其代谢产物。食管癌在非洲发病率最高的地区是在Transkei共和国的西南部,该国东北部的发病率却相对较低,而玉米是该两地区的主食。本文乃调查食管癌高发和低发地区玉米中镰刀菌的发生率及毒素存在情况。样品取自两个食管癌高发区和两个低发区,每一区从50个点任意取最近收获的霉玉米穗,脱粒后混在一起。从各区的玉米粒中分别挑选出肉眼可见明显污染镰刀菌的粒子。取各区的混合样及明显污染样,分别测玉米赤霉
Cook (1971) suggested that the link between farming and esophageal cancer in Africa is clear. Many scholars have reported that corn is susceptible to Fusarium contamination and that there are Fusarium toxins and their metabolites. Esophageal cancer is most prevalent in Africa in the southwestern part of the Transkei Republic, where the morbidity is relatively low in the northeast and maize is the staple food in both regions. This article investigates the incidence of Fusarium and the presence of toxins in maize with high and low incidence of esophageal cancer. Samples were taken from two high incidence areas of esophageal cancer and two low incidence areas, each area from 50 randomly selected recently harvested mildew ear, thresholded and mixed together. From each area of the corn kernels were selected out of the visible visible contamination of Fusarium particles. Take the district of the mixed samples and obviously contaminated samples were screened corn
