我国东南沿海地区织纹螺科的种类与毒性

为了解我国东南沿海地区织纹螺体内的毒素状况,利用生物法对采自我国东南沿海的织纹螺样品毒性进行了测定.实验结果和相关资料表明:织纹螺的毒性与其种类关系密切.光织纹螺(Nassarius rutilans)、正织纹螺(Zeuxis scalaris)和节织纹螺(Nassarius hepaticus)为有毒织纹螺;纵肋织纹螺(Nassarius variciferus)、习见织纹螺(Nassarius dealbatus)和胆形织纹螺(Nassariust hersites)为无毒织纹螺;方格织纹螺(Nassarius clathratus)、西格织纹螺(Nassarius siquinjorensis)、半褶织纹螺(Nassarius semiplicatus)、红带织纹螺(Nassarius succinctus)、疣织纹螺(Nassarius papillosus)、花织纹螺(Zeuxis castus)、素面织纹螺(Nassarius sufflayus)和橡子织纹螺(Nassarius glans)毒性不明,可能为季节性有毒织纹螺.多种织纹螺的毒性变化规律目前尚不清楚,人们应尽量避免食用织纹螺.

The Species and Toxicities of Nassariidae Collected from the Coast of Southeast China Sea

To investigate the distribution of toxic Nassarius in the southeast coast in China, we detected snail samples collected from these areas by bioassay. Results indicated that the toxicity of Nassarius was relative to species. Nassarius rutilans, Zeuxis scalaris, and Nassarius hepaticus were toxic gastropods, and Nassarius variciferus, Nassarius dealbatus, and Nassarius thersites were nontoxic gastropods, while the toxicity of Nassarius clathratus, Nassarius siquinjorensis, Nassarius semiplicatus, Nassarius succinctus, Nassarius papillosus, Zeuxis castus, Nassarius sufflayus, and Nassarius glans probably changed with the season. The change regularity of Nassarius's toxicity is still unknown. Therefore the best way to prevent humans from the harmful effects of Nassarius is to stop eating them.
