  • 揭开祖传蛇药“秘方”的面纱_网易新闻中心 on 2009-11-19
    • 一种药物要能对抗蛇毒,可以有两种方式。一种是直接破坏、消灭毒素。但是蛇毒是蛋白质毒素,一种药物如果能够在体内破坏蛇毒,也就能同时破坏人体的蛋白质,是没有用的。另一种方式是药物抑制了中毒反应。但是蛇毒种类繁多,每一种毒蛇都有自己特别的毒素,中毒反应也各不相同,不可能找到一种药物能够同时对抗各种不同的中毒反应。所以“蛇医部长”声称其祖传秘方能治疗各种毒蛇咬伤,完全不可信。目前公认有效的治疗毒蛇咬伤的方法是注射抗蛇毒血清,它的制作方式是把某种蛇毒注射到马体内,让马的免疫系统产生专门针对该蛇毒的抗体,再将含该抗体的马血清注射到患者体内,就可以让抗体去中和蛇毒素。但是一种抗蛇毒血清只能对抗用来制造它的那种蛇毒,对其他蛇毒就无效了。
