抗氧化剂、微量元素和某些植物性食物对肿瘤的预防已有报道.本文在筛选植物性食物防癌中发现,葵花子仁有良好防癌作用.实验分癌变组,预防组A、B、C和D,各组均按Farber法以二乙基亚硝胺(NDEA)和2-AAF诱发大鼠肝癌前结节.在诱癌前4d, 预防A组每只动物加葵花子仁5～6g/d,B组在饮水中加入亚硒酸钠4μg/L(自由饮用),C组饲料中加维生素C(0.5％),D组为综合预防(即饲料中有葵花子仁.维生素C及含硒自来水).诱癌后分别饲养6周,检测指标为癌变标记物r-谷氨酰转肽酶(r-GT)及其同功酶谱,部分结果见附表,
Antioxidants, trace elements and certain plant foods have been reported for the prevention of tumors. This article was found in the screening of plant foods anti-cancer found that sunflower seeds have a good anti-cancer effect. Experimental sub-cancerous group, prevention group A, B, C And D, each group was induced by Farber’s method with diethylnitrosamine (NDEA) and 2-AAF to induce hepatic nodules in rats. 4 days before the induction of cancer, each animal of group A was prevented from adding 5 to 6 g of sunflower seeds. d, Group B was treated with sodium selenite 4 μg/L (free drinking) in drinking water, Group C was supplemented with vitamin C (0.5%), and Group D was comprehensively prevented (ie, there were sunflower seeds, vitamin C, and selenium in the diet. (Tap water). After cancer induction for 6 weeks, the detection index is the cancerous marker r-glutamyl transpeptidase (r-GT) and its isozyme spectrum. Some results are shown in the attached table.
