摘要
天然水域中存在着一类由毒藻产生的毒素往往经贝类、鱼类等传播媒介造成人类中毒的毒素,而这类毒素通常被称为贝毒素,是一种广泛分布的生物毒素。目前已经研究发现了腹泻性贝毒(Diarrhetic shellfi sh poisoning,DSP)、麻痹性贝毒(Paralytic shellfi sh poisoning,PSP)、神经性贝毒(Neurotoxic shellfi sh poisoning,NSP)、记忆缺损性贝毒(Amnesic shellfi sh poisoning,ASP)和西加鱼毒素(Ciguatoxin,CTX)等5种主要贝类毒素。本文描述了各种毒素其主要特征,介绍了其毒物成分及毒理效应,并对已有的检测方法作以综合性的介绍和评判。其中,有关腹泻性贝毒和麻痹性贝毒的研究报道比较多,检测技术方法应用比较广泛,主要有生物检测,免疫法以及液相色谱等方法;而记忆缺损性贝毒和西加鱼毒素目前研究还相对较少,检测方法以免疫法为主。
Shellfish poisoning is a kind of widespread biotoxin in natural watershed which is transferred by shellfish or fish, and is harmful to humen health. Five kinds of shellfish poisoning are found now, including Diarrhetic shellfish poisoning(DSP), Paralytic shellfi sh poisoning(PSP), Neurotoxic shellfi sh poisoning(NSP), Amnesic shellfi sh poisoning(ASP) and Ciguatoxin(CTX). In this paper, the characterization of different kinds of shellfi sh poisoning and the detection methods are introduced. Some methods can be used conveniently to preserve the GRAS(generally recognized as safe) project in food from watershed.
