Abstract
The effect of dibutyryl 3', 5'-cyclic monophosphate (D-c AMP) on the neuromuscular transmission was studied in a patient with myasthenia gravis during anesthesia. D-cAMP caused a slight increase in single twitch tension, and an initial transient decrease in tension which resulted from the trains of 2 Hz stimuli disappeared after D-cAMP. The finding of the present study suggests that D-cAMP has an anti-fatigue effect in patients with myasthenia gravis.
