作者应用 Fischer 大鼠胚胎细胞培养进行致癌化学物的体外筛检,观察它们对细胞恶性转化的诱导作用。本文系将此法用于筛检食品色素的致癌性;且将色素直接注射于大鼠和地鼠进行体内试验,与之作对比。受试的八种色素是:蓝色1号(亮蓝;三苯甲烷类),蓝色2号(靛蓝类),绿色3号(坚牢绿;三苯甲烷类),红色3号(赤藓红;2,6- The authors used Fischer rat embryo cell culture in vitro screening of carcinogenic chemicals to observe their induction of malignant transformation of cells. This article is the method used to screen the carcinogenicity of food coloring; and the pigment injected directly into rats and hamsters for in vivo tests, compared with. The eight colors tested were: blue No. 1 (brilliant blue; triphenylmethane), blue No. 2 (indigo), green No. 3 (fast green; triphenylmethane), red No. 3 Moss red; 2,6-
