中文摘要:
      为了解节织纹螺的毒性,利用生物法对节织纹螺毒素的变化规律进行研究。实验结果表明:节织纹螺毒素的毒力呈季节性变化,每年的4月至9月是毒力较高的时期,毒力最高达56 MU/g。进一步分析表明,节织纹螺肌肉和中肠腺部分毒力变化略有不同:肌肉部分毒力较高时期是5月至9月,最高达49 MU/g;中肠腺部分毒力较高时期是4月至8月,最高达78 MU/g。从节织纹螺毒素总体分布来看,除4月外,中肠腺所含毒素总量都低于肌肉毒素总量,节织纹螺中的毒素主要存在于肌肉中。由于节织纹螺属大型织纹螺,毒素主要存在可食部分中,一定量食用仍然会引起中毒,广大群众应尽量避免食用节织纹螺。
英文摘要:
      The toxins of Nassarius hepaticus gastropods were studied. The toxicity of the gastropods was detected by the bioassay method. Results showed that the toxin in gastropods were varies with seasonal and from April to September was higher than other period, the highest toxicity was 56 MU/g. The further research revealed that the toxins was different in muscle or digestive gland: the toxin is high from May to September in muscle, the highest toxicity was 49 MU/g; and that was April to August, 79 MU/g in digestive gland. However, the total toxin in muscle was higher than that in digestive gland except April, The mostly toxins of gastropods was in the muscle. Nassarius hepaticus was belong to large size Nassariidae, The mostly toxins was in the edible part, we suggest that everyone should avoid to eat it.
