The effects of phenolic acid compounds in vegetables and fruits on metabolicactivation of BaP in rats,as well as 〓 and TCA induced lipid peroxidation inmouse and Salmonella typhimurium TA104 cells were investigated using DNAadducts as a biomarker to assess DNA damage induced by xenobiotic carcinogens.BaP was used to study the genotoxic carcinogenesis,while 〓 and TCA were usedto study the non-genotoxic carcinogenesis.The possible protection mechanisms ofphenolic acid compounds on DNA damage were studied.

本研究根据化学致癌过程的遗传毒性和非遗传毒性机理，以DNA加合物作为机体接触外来化学物而导致DNA损伤的生物学标志物，通过观察酚酸类化合物对大鼠体内BaP活化代谢以及〓和TCA诱导小鼠肝微粒体脂质过氧化的影响，及酚酸类化合物对BaP和TCA诱导的沙门氏菌TA100和TA104形成DNA加合物的影响，探讨蔬菜、水果中酚酸类化合物对外来化学物诱导的DNA损伤的保护机制。

In the chapter 4, the HPLC analyses of Uridine and Thymidine implanted by ions with high energy are done. The result shows that the dose effect curves of ions with high energy are almost the same to the dose effect curve of ions with low energy. At the beginning, the damage of implanted ions to the sample is large, with the dose increasing, the damage drops sharply.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
