Definitions of Neurine

  1. A poisonous organic base (a ptomaine) formed in the decomposition of protagon with boiling baryta water, and in the putrefraction of proteid matter. It was for a long time considered identical with choline, a crystalline body originally obtained from bile. Chemically, however, choline is oxyethyl-trimethyl-ammonium hydroxide, while neurine is vinyl-trimethyl-ammonium hydroxide. Webster Dictionary DB
  2. A toxic ptomaine, C5H12NO, trimethylvinyl ammonium hydroxide, a product of decomposing animal matter; also a poisonous constituent of mushrooms. 2. An extract of brain matter, suggested for use in various nervous disorders and in cancer. A practical medical dictionary. By Stedman, Thomas Lathrop. Published 1920.
  3. A ptomaine of putrefaction. Warner's pocket medical dictionary of today. By William R. Warner. Published 1898.
  4. The substance which constitutes the matter of the nerves. Nuttall's Standard dictionary of the English language. By Nuttall, P.Austin. Published 1914.
  5. Nervous substance. Etymological and pronouncing dictionary of the English language. By Stormonth, James, Phelp, P. H. Published 1874.
  6. The substance of which the nervous system is composed. It consists chiefly of albumen and a peculiar fatty matter, associated with phosphorus. There are two kinds of neurine-the one vesicular or consisting essentially of nerve vesicles or nerve cells or corpuscles, or, as they are sometimes called, from their prevailing in the ganglia-ganglion corpuscles and ganglion globules; the other, the tubular, formed-as the word imports-of tubules. The former is the cineritions or cortical nervous matter of the older anatomists ;-the latter, the white or medullary. The vesicular neurine has appeared to be restricted to the production and distribution of nerve-power; the tubular, to its conduction; yet the experiments of Dr. Brown-Sequard show, that the former conveys sensitive impressions from the posterior spinal roots to the brain.

  7. A ptomaine, C5H13NO= C2H3.N (CH3)3.OH, or trimethyl-vinyl-ammonium hydrate, produced by the chemical decomposition of protagon, by the putrefaction of flesh and certain fungi, and also obtained synthetically. Extremely poisonous, acting like curare upon the motor-nerve terminals, and producing salivation, primary acceleration followed by secondary and progressive retardation and weakening of pulse and respiration, primary fall and secondary rise of blood-pressure, dyspnoea, miosis, and death by arrest of respiration with clonic convulsions. na
