呼吸作用

At the beginning, the domestic and external scholars studied it on the cattle, rat, lapin, fish , pig and cat etc , the result showed that the physiological effect of Coriaria lactone was similar to that of picrotoxinin , which effected nerve system , made the muscle and respiration exited and the vascular contracted , animated the heart restraint center so lead to the animal coma , startle , spasm etc symptom .

人们很早就认识到了它的毒性，最初国内外学者分别在牛、鼠、兔、蛙、鱼、猪和猫等动物上研究证明，马桑毒素的生理效应与苦毒素的生理效应极其相似，是通过作用于神经系统，产生肌肉兴奋，呼吸亢奋，血管收缩，激活心动抑制中心等从而导致抽搐、昏迷、惊厥、癫痫等症状。
