There is a need to encourage more sophisticated chemical and physical analysis of fire effluents for complex toxic organic species.

因此，很有必要对复杂毒性有机体的火灾燃烧产物进行更深入的物理和化学分析研究以及动物模型研究。

Emetics irritate the increase of Fos positive neurons in relevant regions in the brain of rat, which suggests that there exist relevant neural chemical pathways similar to nausea in the brain of non-vomiting rats.

催吐剂的刺激使大鼠脑内相关区域Fos阳性神经元数量增加，提示非呕吐动物大鼠脑内也存在类似与恶心相关的神经化学通路。

Pollutants from such agricultural sources as farms, pastures, feedlots, and ranches contribute animal wastes, agricultural chemicals, and sediment from erosion.

They say wild animals are being "feminised" by a host of common man-made pollutants which mimic the female sex hormone oestrogen and escape into seas, rivers, the earth and air when waste is disposed of.

科学家警告说，环境中有越来越多可以改变性征的化学物，这对人类和野生动物的繁殖力产生了负面影响。

Methods Fifteen healthy, female SD rats were employed in the experiment. Sensitized systematically with keyhole limpet hemocyanin, the animals were inoculated with the same antigen through cochlea basal turn into the labyrinth. Adminstrated 5-bromo-2′-deoxyuridine intraperitoneally, the rats were sacrificed and the temporal bones were harvested at 3, 7,14 day after labyrinth vaccination respectively. The frozen sections of the decalcified samples were dealt with H-E staining and immunohistohemical methods to investigate the cellular infiltration, BrdUrd and IgG positive cells in the ES.

选用SD大鼠15只，以钥孔虫戚血蓝蛋白（keyhole limpet hemocyanin，KLH）全身免疫后，经耳蜗底回钻孔以相同抗原进行内耳免疫，然后分别在内耳免疫后3、7和14 d腹腔注射溴脱氧尿嘧啶核苷（bromodeoxyuridine，BrdUrd）后处死动物，取颞骨经组织学处理制作冰冻切片，用免疫组织化学技术观察内淋巴囊的细胞浸润、增殖和IgG细胞的分布状况。
