摘要
根据80－90年代国际上对麻痹性贝毒研究的最新进展，就研究中的几个热点问题进行综合评述，包括：麻痹性贝毒产毒藻的识别；毒素产生机制；毒素监测和分析方法；麻痹性贝毒对海洋生物的影响；麻痹性贝毒对水产养殖业的影响及对策等。概括了麻痹性贝毒研究的现状和研究中亟待解决的问题。中国在麻痹性贝毒毒素研究领域只进行了一些初步的工作，本文结合中国的研究现状，提出以后在此领域内的重点研究方向。
Recent Researehes in relation to Ptalytic Shellfish Posoning (PSP) Undertaken in the 1980s and 1990s are discussed. The most important advances are listed below. 1) Immunological and genetical probes have been used in the identification of toxic algas, which could simplify the process of algae examination and enumeration. These tectriques could be further used in field investigations of toxic algal blooms. 2) Bacteria are found to be abe to Produce PSP. Several strains of toxic bacteria have been isolated and cultured successfully in the laboratory. However, other studies indicated that PSP toxin production is generaly related to the toxin algae. Such, the mechanism of toxin production in dinoflagellate remains unclear. 3) New biological and chemical methods have been developed in monitoring and analyzing Paralytic Shellfish Poisoning, such as immunoassays, neuroreceptor binding assays, cytotoxicity bioassays, high performance liquid chromatography (HPLC) and capillary electrophoresis (CE). 4) Studies in an attempt to elucidate toxicological and ecotoxicological effects of Paralytic Shellfish Poisoning have been undertaken. Toxin accumulation and tranformation are confirmed in marine organisms of low trophic level, especially in shellfish. 5) Impacts of Paralytic Shellfish Poisoning on mariculture and according management are summarized. Researeh work on Paralytic Shellfish Poisoning in China started from the beginning of the 1990s. Several researeh fields with priority are proposed asccording tD the Present researeh status in China
