蜘蛛张网捕捉到昆虫后,总要先咬一口猎物,使之“昏迷”,然后才慢慢享用。为什么会出现这种现象呢?科学研究发现,蜘蛛的唾液里含有一种毒素,它可抑制动物体内谷氨酸的活动。蜘蛛唾液的这一功能引起科学家的兴趣,因为人体脑细胞内的谷氨酸急剧增加就会造成组胞死亡,导致发生脑溢血、脑血栓。日本山多利生物有机科学研究所的专家们据此采用以毒攻毒的方法,将蜘蛛毒素与成份相同的人工毒素进行混合调制成抑制谷氨酸的新药。目前新药已进行了动物试验。眼镜蛇唾液的毒性令人咋舌,被其咬中的猎物几乎无一幸免于
After catching the insects, the spider Zhang network must first bite a prey, make it “coma”, and then slowly enjoy. Why does this phenomenon occur? Scientific research has found that spider saliva contains a toxin that inhibits glutamate activity in animals. This function of spider saliva has attracted the interest of scientists, because the rapid increase in glutamate in human brain cells will cause the death of histocytes, resulting in cerebral hemorrhage and cerebral thrombosis. According to this method, experts from the Santori Institute of Bio-Organic Research in Japan used a method of poisoning and poisoning to mix spider toxins and artificial toxins with the same composition into a new drug that inhibits glutamate. At present, new drugs have been tested in animals. The toxicity of Cobra’s saliva is staggering, and almost none of its prey caught by its bite
