RT Journal Article SR Electronic T1 A NEUROPHARMACOLOGICAL STUDY ON THE EFFECT OF MYANESIN (TOLSEROL) ON MOTOR SYSTEMS JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 331 OP 341 VO 97 IS 3 A1 ELWOOD HENNEMAN A1 ARNOLD KAPLAN A1 KLAUS UNNA YR 1949 UL http://jpet.aspetjournals.org/content/97/3/331.abstract AB New techniques have been described whereby drugs affecting the extrapyramidal system may be tested. With them it has been demonstrated that: (1) Myanesin decreases or abolishes facilitation and inhibition reaching anterior horn cells from all levels of the C.N.S. (2) Neural circuits containing internuncial cells are vulnerable to Myanesin, whereas "direct" circuits withstand large doses without effect. (3) Relief of spasticity by Myanesin can be explained in terms of these effects. (4) The site of action of Myanesin is probably the internuncial cell. 1949 by The American Society for Pharmacology and Experimental Therapeutics
