Study on DNA Damage Caused by F-2 Toxin

F-2毒素致DNA损伤研究

In F-2 population the segregation of molecular markers were in consistent with expected ratio of two independent genes .

由于这样的分子标记实际上就是功能基因本身局部片断的扩增结果，所以能非常可靠地直接鉴别该功能基因，F2群体中分子标记的分离比例与2对基因的独立分配比例完全一致。

DNA damage of HELA cells by F-2 toxin was determined by single-cell gel electrophoresis ( SCGE ) .

目的研究F-2毒素引起体外培养细胞（HELA细胞）的DNA损伤。方法应用单细胞凝胶电泳技术（SCGE），测定玉米赤霉烯酮，即F-2毒素。

Effects of Bacillus subtilis F-1 and F-2 on inhibiting the growth of Fusarium oxysporum f.sp .

枯草芽孢杆菌F-1和F-2与尖孢镰刀菌的对峙实验中，F-1没有抑菌作用，而F-2表现出强抑菌效果。

The results showed that F-2 toxin had no effect on the level of LDH , but decreased the synthetic capability of albumin and DNA in cultured hepatocytes .

结果表明：F-2毒素对肝细胞分泌LDH无影响，但可使白蛋白和DNA合成下降。

In this paper , the self-made dispersant F-2 , organic slow dilution agent , early strength agent and activator are sieved by MTC composition .

本文选用自制的分散剂F-2，有机缓凝剂，早强剂及激活剂进行了大量的MTC配方筛选。

Objective : To study the effects of quaternary ammonium salt derivative of haloperidol ( F-2 ) on experimental arrhythmia induced by barium chloride ( BaCl-2 ) .

目的：研究氟哌啶醇季铵盐衍生物（F2）抗实验性大鼠心律失常的作用。

Based on orthogonal space-time coding and the F-2 norm of received signal vector , a non-coherent antenna selection algorithm , which does not require to estimate channel parameters , is presented in this paper .

基于正交空时编码和接收信号向量的范数，提出了非相干的天线选择算法（NON-AS），不需要估计信道，并将算法应用于差分空时系统。

During logarithmic phase of cultivated ovary granulose cell , experiments were carried out to investigate the genetically procreation toxicity of F-2 toxin and the detoxification of V-E.

采用细胞体外培养的方法，在卵巢颗粒细胞对数生长期，对F-2毒素的繁殖遗传毒性和V-E对其的解毒作用进行了研究。

It suggests that F-2 toxin decrease viability of ovary granulosa cell by inducting lipid peroxidation , and V-E has a great detoxication on F-2 toxin as well as protective effects on ovary granulosa cells exposed to F-2 toxin .

这表明，F-2毒素可能是通过脂质过氧化作用，对颗粒细胞致毒，V-E对F-2毒素具有较好的解毒作用，能提高中毒卵巢颗粒细胞的抗过氧化能力。

The comparison of GC-MS analysis of partially methylated alditol acetates made before and after the desulfation of F-2 presents useful structural information on F-2 , including the composition of its main chains and side chains , the linkage pattern and sulfation positions .

对F2脱硫前后部分甲基化糖醇乙酸酯的GCMS进行分析比较，得出F2的结构信息，包括其主链和支链的构成、连接方式和硫酸基取代位置等。
