In order to block acetylcholine receptors of muscle, the alpha toxin of the Formosan cobra (Naja naja atra) was given intraveonously to rats. Electrophysiological and pharmacological changes typical of myasthenia gravis were recorded, including decremental responses to repetitive stimuli, curare sensitivity, neostigmine reversal, and posttetanic phenomena. This model supports the concept that a reduction of available acetylcholine receptors may play an important role in myasthenia gravis.
