亚硝酸钠和亚硫酸钠均是食品工业中常用的添加剂。利用紫露草微核技术监测和比较它们的致突性,并用维生素C作为抗突变剂进行试验。结果证明,紫露草花枝在以上两种食品添加剂处理液中其四分体核微数均明显增加,说明两种添加剂均有致突作用,而且前者远高于后者。如同时加入维适量生素c,微核率显著下降,表明维生素c对其致突性具有拮抗作用,是一种较好的抗诱变剂。
Both sodium nitrite and sodium sulfite are commonly used additives in the food industry. The rhabdosaurus micronucleus technique was used to monitor and compare their burstiness and to test with vitamin C as an antimutagenic agent. The results showed that the micro-numbers of the tetrads in the treatment plants of Radix violacea were significantly increased in the above two food additive treatment solutions, indicating that both additives had a conic effect, and the former was much higher than the latter. If vitamin C is added at the same time, the micronucleus rate is significantly decreased, indicating that vitamin c has an antagonistic effect on its rabies, which is a good antimutagenic agent.
