克痛灵是我室生化组从眼镜蛇毒中提纯的一种神经毒素制剂,它不含心脏毒成分,也无酶活性。二年多来,经700多病例试用证实对各种慢性顽固性疼痛有较好的疗效。克痛灵的镇痛机制我们正在研究中,目前还未弄清。克痛灵对实验动物的呼吸系统和血循系统的作用和提高痛阈我们作了初步研究,现报导如下。 Ketongling is a neurotoxin preparation purified from the cobra venom by the Biochemical Group of our chamber. It contains no heart toxic components and no enzymatic activity. Over the past two years, more than 700 cases have been confirmed to have a good effect on chronic intractable pain. Ketongling’s analgesic mechanism we are studying is still not clear. Ketongling has conducted preliminary studies on the effects of the respiratory system and blood circulation system of experimental animals and on increasing the pain threshold. The following are reported.
