[Action of physostigmine on the acetylcholine content of the bovine choroid (author's transl)].

The measurement of the acetylcholine (ACh) content of 12 choroids influenced by a 1% solution of physostigmine salicylate (10 applications of three drops at three minute intervals) into the conjunctival fornix of one eye demonstrated elevated average values for ACh content (0.87 microgram) compared with those for the control eye (0.75 microgram). The eyes were enucleated one hour after the last application.
