此外，现有的经口铜毒性资料多为经饲料或一次灌胃暴露的动物资料，尚缺乏由饮水铜暴露导致的较为全面的毒性和代谢影响研究？

This study has achieved the following purposes,observed effects of different levels of noise exposure on the auditory function and the hearing organ of guinea pigs,explored optimal noise exposure profiles for research of NIHL susceptibility,established NIHL susceptibility model,148 differentially expressed genes of cochlea between NIHL susceptible and unsusceptible guinea pigs were screened by using suppression subtractive hybridization.The results of bioinformatics analysis showed that there are 34 sequences whose homology were larger than 80% and match sequence larger than 100 bp.

本研究观察了不同噪声暴露量对豚鼠听觉功能和听觉器官结构的影响，探讨了NIHL易感性研究的最佳噪声暴露方案，建立了NIHL易感豚鼠模型，利用抑制性消减杂交技术筛选NIHL易感与不易感豚鼠耳蜗的差异表达基因片段148条，生物信息学结果显示同源性大于80%且匹配碱基大于100 bp的片段共34条。

In the simulated experiments, the effects of long-term exposure of dibutyl phthalate on contents of malondialdehyde, solubility carbohydrate, blade pigment, protein, glutathione and amino acid of Vallisneria spiralis L were studied. The cultivation period was 25 days. The effects on the growth of Vallisneria spiralis L under the stress of DBP was also invertigated in this paper. Vallisneria spiralis L was damaged seriously in long-term exposure of high concentration DBP.

以沉水植物苦草为试验材料，通过模拟实验研究了邻苯二甲酸二丁酯长期暴露对苦草的生长状况以及丙二醛、可溶性糖、叶绿素、谷胱甘肽、蛋白质和氨基酸的含量等生理生化指标的影响，试验结果表明：高浓度DBP长期暴露对苦草生长有严重伤害，DBP对苦草丙二醛和可溶性糖含量以及叶片中叶绿素含量的影响比较相似，都有一定的起伏。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.
