中国鲎和圆尾鲎组织毒性的初步研究

Study on the toxicity of horseshoe crabs in mice

以昆明种小白鼠进行中国鲎和圆尾鲎组织的提取物毒性试验。结果发现圆尾鲎的毒性远远大于中国鲎。圆尾鲎致小白鼠死亡的征象为急动、惊跳而死 ,与河豚毒素中毒特点类似 ;而中国鲎中毒则为静伏昏睡而死。成鲎的毒性均比幼鲎大。

In order to study the toxicity of horseshoe crabs (tachypleus tridentatus and carcinoscorpius rotundicauda) in the sea of China, the extracts of tissues from tachypleus tridentatus and carcinoscorpius rotundicauda were injected into the abdominal cavity of mice for testing their poisoning effects. The results showed that the toxicity of carcinoscorpius rotundicauda was much higher than that of tachypleus tridentatus. The length of time from the injection to the death was much shorter for Carcinoscorpius rotundicauda than that for tachypleus tridentatus. The signs before death for Carcinoscorpius rotundicauda poisoning were restless, jumping and spasm but that for Tachypleus tridentatus was lethargy. The toxicity of adult horseshoe crabs was much higher than that of young horseshoe crabs.
