In order to study Kaschi-Beck Disease in relation with environmental selenium, authors have collected samples of driking water, soils, various kinds of grains and children's hair from 130 locations in both affected and nonaffec-ted areas according to different natural and geographical types in Shanxi Province from 1978 to 1981, and also analyses of selenium were made in these samples.

In order to study Kaschi-Beck Disease in relation with environmental selenium, authors have collected samples of driking water, soils, various kinds of grains and children's hair from 130 locations in both affected and nonaffec-ted areas according to different natural and geographical types in Shanxi Province from 1978 to 1981, and also analyses of selenium were made in these samples. It can be seen from the results that the disease-affected areas all are of an environment where the selenium content stands very low, for exemple, in drinking water less than 0.2ppb, in grains (average of wheat and corn)less than 10 ppb over 95% of the samples examined, while in hair, which reflects Se content in human body, less than 110 ppb over 92% of 478 children. In contrast, the areas where there shows no Kaschi-Beck Disease are of an environment with low, medium and high Se content in water, soils and grains.The amount of Se provided for the children from water and grains has been calculated 5.4μg or so the lowest daily uptake in the non-affected areas. It can also be shown by analyzing the results of the samples in all the locations that the amount of selenium in grains consists of up to 90% of the total amount of Se in grains and water in most locations in the areas, and it has also indicated that grains are the main Se source in these areas. But in areas where Se content in grains is low and that in water is high, Se from water may have a bigger contribution to Se in human body, and thereisn't Kaschi-Beck Disease so far found.

本文作者为研究环境中的硒与大骨节病的关系,于1978—1981年在陕西省不同自然类型区的130余个大骨节病点和非病点,采集了饮水、土壤、粮食与儿童发样进行硒的分析研究。结果表明,病点均处于硒很低的环境,其中95%以上的病点饮水含硒量在0.2ppb以下,粮食含硒量(小麦、玉米平均值)在10ppb以下,反映人体硒水平的发硒含量,478名儿童中有92%在110ppb以下。但是,没有大骨节病的地区则处于较低硒、中硒和高硒环境。同时,经估算每日由水、粮供给人体(儿童)的硒量,看出5.4μg左右是非病点每日由水、粮供给硒量的最低值。从所有地点的分析结果看出,大部分地点的粮食供硒量占水、粮供硒总量的90%以上,说明粮食是这些地区人体摄入硒的主要来源。但是在粮食硒含量低的地点,无论是非病区或病区范围内,只要水硒含量高,就无大骨节病。 作者还介绍了在病区对患病儿童采取补充硒的措施,可以提高发硒含量达到非病区儿童的发硒水平,同时对预防大骨节病有明显效果,这就进一步证明了大骨节病的产生很可能与环境中的硒低有关。

A series of study on toxicity was conducted of natural pigment extracted from cocoa bean shells. On the basis of the negative results obtained in the experiments, we made the safety evaluation of its pigment. The results showed that in the high dose groups, the average intake of the pigment ranged from 1.129mg/kg bw to 1.378mg/kg bw per day, but there was no significant difference(P>0.05) between the parameters of the experimental groups and the control. An amount of about 0.5~0.8 gm of brown pigment is usually...

A series of study on toxicity was conducted of natural pigment extracted from cocoa bean shells. On the basis of the negative results obtained in the experiments, we made the safety evaluation of its pigment. The results showed that in the high dose groups, the average intake of the pigment ranged from 1.129mg/kg bw to 1.378mg/kg bw per day, but there was no significant difference(P>0.05) between the parameters of the experimental groups and the control. An amount of about 0.5~0.8 gm of brown pigment is usually added into per kg of food in food processing. If a child weighing 25 kg takes 250 gm of food of this kind per day. 5~8mg/kg bw of brown pigment will be absorbed. Although in the high dose groups. rats of both sexes absorbed this kind of pigment 140 times more than man did, no toxic effects were observed. The results of all toxicity tests of the pigment demonstrated neither acute nor chronic toxicity. We consider, therefore, the brown pigment to be safe. as a food additive, and an economic and promising edible natural pigment in food processing.

对可可豆壳中提炼出的天然色素进行了一系列毒性研究。在所有实验取得阴性结果的基础上,对该色素进行了安全评价。结果表明,最高剂量组大鼠平均每天摄入的色素量为1.129 mg/kg bw至1.378 mg/kg bw,各项观察指标与对照组无显著差别(P>0.05)。棕色素一般每公斤食品添加0.5~0.8 g,如果一个体重25公斤的儿童每天吃250g这种食品,则将摄入5~8 mg/kg bw棕色素。现最高剂量组两性大鼠摄入的色素超过人体摄入量的140倍以上,未发现毒作用。根据色素的全部毒性试验结果,未出现急、慢性毒性。我们认为,该棕色素作为食品添加剂是安全的,在食品加工中是一种比较经济和有发展前途的食用天然色素。

Many scientists have paid great attention to the internal carcinogens for the last ten years. The typical examples of the predecessors of N-nitro compounds were nitrate and nitrite.lt has been confirmed by animal experiments that nitrate and nitrite,when absorbed by the human body from food, may result in a higher morbidity rate of cancers.In this study,Yangzhoag county, where the mortality rate of esophageal cancer were as high as 2.84‰,has been taken as a rest area,and Nanjing city as a check.'Nitrate and nitrite contents in several kinds of foods (including vegetables, grains, meat, fish drinking water etc.) were measured from the view point of food composition and the Value of the contents was compared with that of ADI stipulated by WHO/PAD. The results showed that the average NO-, amount absorbed by human body in a season time in Yanzhong was 2.1-2.4 times more than the standard Value, and 1.63-1.67 times higher than in Nanjing. More than 9% of nitrate absorbed, came chiefly from fresh vegetables, 2-14% from pickles, 1-3>% from grain and meat as were as from drinking water. Moreover, among different vegetables, leaf vegetables contained the highest contents of nitrate, eggplant and fruit Vegetables contained the lowest. During winter and spring, when leaf Vegetables were prevalent in market, more nitrate was liable to be absorbed. The evaluation of food compositions,screening Vegetables with lower nitrate content, and to improve diet of people would be important measures lo decrease the morbidity rate of cancers.

近几十年来,内源性致癌物质引起了许多学者的关注。亚硝酸化合物的前体——硝酸盐和亚硝酸盐正是这类物质的典型代表。人体从食物中摄入过量的这些前体,将可能使肿瘤发病率增高。这在动物试验已经证实。本文以我国食管癌高发区扬中县(癌亡率达2.84‰)为实验点,南京市为对照点。从膳食结构角度出发,分析测定了各种食物(色括蔬菜、粮食、肉类、鱼类、饮水等)中的硝酸盐和亚硝酸盐的含量,并按照WHO/FAO规定的ADI值进行评价,发现扬中县人体季均摄入的NO_2~-超标2.1—2.4倍,而南京市则为1.63—1.67倍。人体摄入的硝酸盐主要来源于蔬菜,占90%以上,咸菜占2—14%,粮食、肉类及饮水中仅占1—3%,而蔬菜类中,又以叶菜类的硝酸盐含量最高,茄果类最低。冬春季节市场主要以叶菜类为主,此时人体摄入的硝酸盐也高于其它季节。因此,如何综合评价食物结构,筛选硝酸盐富集低的蔬菜以及改进食用方式,将是降低癌症发病率的重要措施之一。
