摘要
用“广西蛇药”115g/kg灌胃,对皮下注射了90%±10%致死剂量眼镜蛇毒、眼镜王蛇毒、银环蛇毒后小白鼠的保护率分别为68~90.5%、78.6~78.8%、46.5%。对70g/kg灌胃皮下注射致死量眼镜蛇毒中毒狗的保护率为50%。若预先于注毒前二小时给35g/kg,注毒时再给35g/kg,存活数提高至4/4。“广西蛇药”灌胃及腹腔给药的半数致死量分别为312.8±41.1g/kg及28.3±5.6g/kg。狗以临床日剂量的5、10倍灌胃14天,血象、肝肾功能及实质器官检查均未发现异常变化。药理实验表明:“广西蛇药”有增强乙酰胆碱兴奋蛙腹直肌和轻度的抗蛇毒抑制大鼠胫神经胫前肌的收缩作用,并有镇痛、镇静、催眠、抑菌、利尿、减慢心率、降压、加快呼吸、延长出血时间等作用。
