Deoxynivalenol is a type of harmful mycotoxin produced by Fusarium graminearum Schwabe teleomorph Gibberella zeae (Schwein Petch when fusarium head blight is epidemic in wheat. DON contamination in harvested grain can significantly lower market grade, and result in significant discount in price to the farmers.

脱氧雪腐镰刀菌烯醇(Deoxynivalenol， DON)是小麦遭受赤霉病危害后由赤霉病菌－禾谷镰刀菌产生的一种真菌毒素，这种毒素对人类和家畜的健康产生危害，严重地影响小麦的利用价值。

In this study, an attempt is made to account for the observed difference in the susceptibility of Gossypium hirsutum L.(cv. BD-18 and Simian 3, resistant and susceptible to V. dahliae, respectively) to toxin of Verticillium dahliae, by looking for differences in the timing and level of production of NO and H_2O_2, and their effects on the expression of GST gene.

本实验以棉花抗病品种BD-18和感病品种泗棉三号的悬浮细胞为材料，研究了棉花细胞在黄萎病菌毒素处理后H_2O_2和NO的变化，并用半定量RT-PCR的方法检测毒素、H_2O_2和NO对棉花谷胱苷肽-S-转移酶基因转录水平的影响。

The chain-forming dinoflagellate Gymnodinium catenatum was only one species in Gymnodinoid known that produces paralytic shellfish poison which had a negative impact on marin environment,aquaculture and human health.

"Gyromitra esculenta toxin is usually destroyed by cooking, but in susceptible people it affects the central nervous system and breaks down blood cells, causing jaundice."

马鞍菌所含的毒素可被加热灭活，但有些人却对这些毒素高度敏感，影响到中枢神经系统，并可致溶血性黄疸。

"Gyromitra esculenta toxin is usually destroy ed by cooking, but in susceptible people it affects the central nervous system and breaks down blood cells, causing jaundice."

马鞍菌所含的毒素可被加热灭活，但有些人却对这些毒素高度敏感，影响到中枢神经系统，并可致溶血性黄疸。

Objective: In order to provide sensitive and reliable technique for the study of the relationship between enviromental estrogens and diseases, analytical methods for three kinds of representative environmental estrogens such as mycotoxins (zearalenone and its metabolites, aflatoxin B_1 and ochratoxin A), persistent pesticide pollutants (hexachlorocyclohexane and dichlorodiphenyltrichloroethane) and industrial chemicals (bisphenol A and 4-nonylphenol) with chromatography were to develop.

目的：选择三种有代表性的环境雌激素：真菌类毒素(玉米赤霉烯酮及其代谢物及赭曲霉毒素A、黄曲霉毒素B_1)、农药类持久性污染物(666、DDT)和化工原料类雌激素为对象，分别研究它们的检测方法，为监控环境激素和研究它们与疾病之间关系提供灵敏、可靠的分析方法和实验依据。

Objective To research on the lysogenic bacteriophage CTXΦ genome, for isogenous sequences with RS in the chromosomes were found in some strains of ctxAB- E1 Tor biotype isolates in this lab.

目的 近年研究发现产毒霍乱弧菌的毒素基因ctxAB由其溶原性噬菌体CTXΦ编码，这种丝状噬菌体可携带ctxAB传递给无毒素基因的霍乱菌株。

We may well explain why ricin-induced apoptosis showed no typical DNA ladder. The presence of laddering in DNA gels implies an apoptosis process, but its absence does not rule out the apoptosis. The ricin 0.05μmol〓 had no effect on the 〓 phase of cell cycle, but induced 〓 arrest. The ricin may affect the balance of synthesis and destruction of proteins that controlling the cell cycle.

检测到DNA梯度表明细胞发生了细胞凋亡，未检测到DNA梯度不能否认凋亡的存在。0.05μmol.L〓的蓖麻毒素对HeLa细胞周期的G〓/G〓期无影响，而诱导了G〓/M期阻滞，蓖麻毒素可能引起一些控制细胞周期蛋白的合成与降解发生紊乱。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
