RT Journal Article SR Electronic T1 THE ESTIMATION BY A MANOMETRIC METHOD OF THE ACTIVITY OF CHOLINESTERASE IN LYMPH JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 246 OP 252 VO 71 IS 3 A1 DALE G. FRIEND A1 OTTO KRAYER YR 1941 UL http://jpet.aspetjournals.org/content/71/3/246.abstract AB 1. A manometric method for the determination of the activity of cholinesterase in body fluids and tissue extracts is described. Of the species of animals examined, the activity of cholinesterase is highest in the serum of horse and man, lower in the dog, and lowest in the cat. 2. The cholinesterase activity of thoracic lymph and cervical lymph of dogs, per cubic centimeter, is distinctly less than the cholinesterase activity of serum. 3. Prostigmine methylsulfate given by mouth or by intravenous injection inhibits the activity of the cholinesterase in thoracic and cervical lymph.
