Hours later,these mice were decapitated,and the striatums were isolated from thebrains. The levels of dopamine, serotonin ( 5-HT ), homovanillic acid, 5-hydroxyindoleacetic acid ( 5-HIAA ) andnorepinephrinein the striatum were measured by high-performance liquid chromatography with electrochemical detection.

给3组小鼠分别喂食Dieldrin 50 mg·kg-1体重、Dieldrin 40 mg·kg-1体重和等量的生理盐水，3 h后处死小鼠，取纹状体匀浆用高效液相色谱-电化学检测法测定纹状体中多巴胺、5-羟色胺(5-HT)、高香草酸、5-羟基吲哚乙酸(5-HIAA)和去甲肾上腺素的含量。

Dieldrin at great dose can influence metabolism of DA in the striatum of mice and it may be one of the environ-mental factors inducing Parkinson's disease.

大剂量的Dieldrin可影响小鼠纹状体中DA的代谢，可能是致帕金森病的环境因素之一。

Results :Dieldrin(50 mg/kg body weight)can decrease the concentrations of DA and NA in the striatum of mice.

结果：喂食Dieldrin 50 mg·kg-1体重能降低小鼠纹状体中NA、DA及HVA的含量。

Relief efforts are proved most fruitful due to the effectiveness of certain pesticides. Dieldrin, the most effective locust killer, has been widely accepted in many countries.

第三段后半部分说大多数批准使用的杀虫剂效果都不明显，药效不强的杀虫剂使救援行动受到限制，而最有效的杀虫剂Dieldrin对人体有害而被禁用，所以其余几项不对。

Aim:To study the effect of Dieldrin on dopamine,serotonin(5-HT)and their metabolites. Methods : The C57-BL mice were divided into 3 groups,and were administrated orally Dieldrin 50mg/kg body weight,40mg/kg body weight andequal amount normal saline ,respectively.

目的：探讨急性Dieldrin中毒对C57BL小鼠纹状体多巴胺及其代谢产物含量的影响。

Both methods are time- and solvent-consuming during the processing. In this study, headspace solid-phase dynamic extraction was applied to exame 13 organochlorine pesticides (γ-HCH、heptachlor、δ-HCH、aldrin、heptachlor epoxide、o,p'-DDE、α-endosulfan、p,p'-DDE、dieldrin、endrin、o,p'-DDT、β-endosulfan、p,p'-DDT) in water and soils. That was a rapid, solvent free and no clean-up procedures technology.

本研究以近年发展之顶空微针动态抽取技术(Headspace solid-phase dynamic extraction， HS-SPDE)进行水及土壤中十三种有机氯农药(γ-HCH、heptachlor、δ-HCH、aldrin、heptachlor epoxide、o，p'-DDE、α-endosulfan、p，p'-DDE、dieldrin、endrin、o，p'-DDT、β-endosulfan、p，p'-DDT)检测方法建立，此技术为一无需溶剂萃取，不需净化之快速检测方法。
