The synergistic potential of 1-hydroxyanthraquinone (1-HA) on methylazoxymethanol (MAM) acetate-induced carcinogenesis was investigated in rats. A total of 154 inbred ACI/N rats (73 males and 81 females), six weeks old at the start of the experiment, were divided into four groups: group 1 was given i.p. injections of MAM acetate (25 mg/kg body wt), once per week for 2 weeks and then fed the diet containing 1% 1-HA for 42 weeks; group 2 received MAM acetate and was kept on the basal diet alone; group 3 was given 1-HA containing diet alone as for group 1; group 4 was treated as a control. At the termination of the experiment, the carcinogenic effect of MAM acetate and 1-HA in the large bowel or liver exceeded the sum of effects when given alone, indicating that the two chemicals act synergistically in the carcinogenesis of these organs.
在大鼠中研究了1-羟基蒽醌(1-HA)对乙酸甲基偶氮甲醇(MAM)诱导致癌作用的协同潜力。实验开始时共有154只近交系ACI/N大鼠(73只雄性和81只雌性),六周龄,分为四组:第1组腹腔注射乙酸MAM(25mg/kg体重),每周一次,共2周,然后喂食含1% 1-HA的饲料42周;第2组接受乙酸MAM并仅喂食基础饲料;第3组与第1组一样仅喂食含1-HA的饲料;第4组作为对照。实验结束时,乙酸MAM和1-HA在大肠或肝脏中的致癌作用超过单独给药时的作用总和,表明这两种化学物质在这些器官的致癌过程中起协同作用。
