title: Acetylcholine and cholinesterase in submandibular glands of rats given armin and obidoxime.
abstract: The effects of obidoxime, a pyridinium oxime, on the cholinesterase activity and acetylcholine content of the submandibular glands of rats poisoned with armin, an organophosphorus anticholinesterase agent, were studied. The results indicate that obidoxime-induced reactivation of phosphorylated cholinesterase can suppress completely the increase in the concentration of acetylcholine that develops within the submandibular gland after administration of armin alone.
