摘要: 背景与目的: 检测三丁基锡 (Tributyltin,TBT)对大鼠脑乙酰胆碱酯酶(AChE)活性的影响,探讨AChE与TBT毒性作用的关系。 材料与方法: SD大鼠共48只随机分为4组,每组12只,分别为对照组(0 mg/kg TBT)和3个实验组(0.1、1、10 mg/kg TBT),对大鼠进行灌胃染毒,在第4、8、12 d时分别于各组中取4只大鼠的脑组织,测定AChE水平。 结果: TBT能够引起大鼠脑AChE活性升高,随染毒剂量的升高和暴露时间的延长AChE活性升高趋势增强。 结论: TBT诱导大鼠脑AChE活性升高可能与TBT的神经毒性相关。

Abstract: BACKGROUND & AIM: The study investigated the effect of tributyltin (TBT) on the activities of acetylcholinesterase(AChE)in brain of rats. The possible relationship between AChE and the toxicity of TBT was discussed. MATERIAL AND METHODS:48 SD rats were divided randomly into 4 groups,12 rats in each group.Experimental groups received 0.1,1 or 10 mg/kg TBT by oral gavage and same volume olive oil was given to control group(0 mg/kg TBT).The brain tissues were obtained from 4 rats in each group at the 4th,8th and 12th day and the AChE activities were measured. RESULTS: TBT exposure could lead to AChE activity elevation in rat brains, and in a dose-related and time-depending manner. CONCLUSION: The increase of AChE activity could possibly be related to the neurotoxicity of TBT.

Key words: tributyltin, acetylcholinesterase, neurotoxicity
