氯酚

An improved method that facilitates the extraction of PCR-compatible faecal DNA from giant panda\'s faeces is described. The method involves a novel preprocessing step in DNA extraction. The faeces is washed two or three times with precooled acetone, which removes numerous potential PCR inhibitors, and then digested with proteinase K. The DNA is purified with phenol/chloroform.

在粪便DNA的提取过程中采用一个新的预处理方法，将粪便用预冷的丙酮洗2～3次，除去粪便中含有的大量PCR抑制物，然后蛋白酶K裂解、酚-氯仿抽提，能提取到纯度很高的DNA供PCR扩增。

Peroxidases and phenol oxidases are the key enzymes in this process.

参与脱氯的关键酶系主要包括过氧化物酶和酚氧化酶。

Sodium arsenite group and sodium arsenate group were made by 300 mg/L per day of sodium arsenite and sodium arsenate respectively. The mice were sacrificed after 10 months for liver function and pathologic examination. The expression of MMp-8, TIMP-2, Col-Ⅰ、Col-Ⅲ mRNA were detected with real time flourescence quantitative PCR. The result was controlled with 18s.
