肉毒毒素是已知毒性最烈的一种毒物,它不但可以引起人的中毒,也可以引起许多种動物的中毒。为了解肉毒中毒的動物模型,我们使用了肉毒毒素耳静脉注射,观察家兔实验性肉毒中毒的过程。报告如下。材料和方法选用健康家兔20只,随机分为两组。A组每公斤体重耳静脉注射A型肉毒毒素0.5毫升。B组每公斤体重注射B型肉毒毒素0.5毫升。注射前观察動物的饮食、活動、呼吸 Botulinum toxin is one of the most toxic known toxic, it can not only cause human poisoning can also cause poisoning of many species of animals. To understand the animal model of botulism, we used botulinum toxin injections into the ear to observe the experimental botulism in rabbits. The report is as follows. Materials and Methods Twenty healthy rabbits were randomly divided into two groups. A group of 0.5 mg of botulinum toxin type A per kg body weight of the ear vein injection. Group B injected 0.5 ml of botulinum toxin type B per kilogram of body weight. Observed before the injection of animal food, activity, breathing
