Ko Kuei Chen (1898–1988) was a scientist who headed up pharmacological research at Eli Lilly and Company for 34 years.
 He is known for his work with ephedrine, cyanide poisoning therapy, and toad venom steroids.
 Tops among his many awards and recognitions is the prestigious Remington Honor Medal for excellence in pharmacy in 1965.
Veterinary support personnel in France are organized according to "La Convention Collective Nationale des Cabinets et Cliniques Vétérinaires", a state sponsored trade union organized by French veterinarians, and consist of five pay echelons.
 Echelon 1 consists of housekeeping and maintenance personnel, echelon 2 consists of reception and secretarial personnel, while echelons 3-5 are "Auxiliaires Vétérinaires" directly responsible for animal care.
 Those working at echelons 4 and 5 have undergone formal apprenticeships, administered by "le Groupement d'Intérét Public Formation Santé Animale et Auxiliaire vétérinaire" (GIPSA),of one and two years respectively and are titled "Auxiliaires Vétérinaires Quatre" (AVQ or AV4) and "Auxiliaire Spécialisé Vétérinaire" (ASV).
 The former's job description is similar to that of the approved veterinary assistant in North America while the latter's job description is similar to veterinary technicians in North America.
 The title of "Technicien en Santé Animale" (TSA) is also used in France but is awarded after a college level course of study in animal health and is not a replacement for the officially recognized titles of AVQ and ASV.
 Those in possession of a combination of the titles TSA and ASV are the equivalents of veterinary technologists in North America and can often be found working in production animal medicine, pharmacological research, or at veterinary school teaching hospitals.
 At present there is not an official national association representing the interests of veterinary auxiliaries.
Pharmacological Research is a monthly peer-reviewed scientific journal covering pharmacology.
 It was established in 1969 as Pharmacological Research Communications, obtaining its current name in 1989.
 It is published by Elsevier and the editor-in-chief is Emilio Clementi (University of Milan).
 According to the "Journal Citation Reports", the journal has a 2014 impact factor of 4.408.
Tetramethylammonium (TMA) or (MeN) is the simplest quaternary ammonium cation consisting of four methyl groups attached to a central nitrogen atom, and is isoelectronic with neopentane.
 It is positively charged and must exist in association with a counter-ion, and is most commonly found in simple salts such as tetramethylammonium chloride, tetramethylammonium bromide, tetramethylammonium iodide and tetramethylammonium hydroxide, and can also form the unusual auride.
 Tetramethylammonium salts are used in chemical synthesis and are widely employed in pharmacological research.
 They also occur as toxic natural products, although the counterions may be difficult to identify.
 The identity of the anion associated with the tetramethylammonium cation frequently has little or no bearing on a particular chemical or biological type of action, but this is not invariably so.

Eli Lilly and Company is an American global pharmaceutical company with headquarters located in Indianapolis, Indiana, in the United States.
 The company also has offices in Puerto Rico and 17 other countries.
 Its products are sold in approximately 125 countries.
 The company was founded in 1876 by Col. Eli Lilly, a pharmaceutical chemist and veteran of the American Civil War, after whom the company was named.
 Eli Lilly and Company is listed on the New York Stock Exchange and its shares have been a component of the S&P 500 Index since 1971.
Erinacines are natural substances isolated from "Hericium erinaceum".
 They belong to the group of cyathin diterpenoids (erinacines A-K, P, and Q) and are subjects of pharmacological research.
Gelsemine (CHNO) is an indole alkaloid isolated from flowering plants of the genus "Gelsemium", a plant native to the subtropical and tropical Americas, and southeast Asia, and is a highly toxic compound that acts as a paralytic, exposure to which can result in death.
 It has generally potent activity as an agonist of the mammalian glycine receptor, the activation of which leads to an inhibitory postsynaptic potential in neurons following chloride ion influx, and systemically, to muscle relaxation of varying intensity and deleterious effect.
 Despite its danger and toxicity, recent pharmacological research has suggested that the biological activities of this compound may offer opportunities for developing treatments related to xenobiotic- or diet-induced oxidative stress, and of anxiety and other conditions, with ongoing research including attempts to identify safer derivatives and analogs to make use of gelsemine's beneficial effects.
Silvio Garattini (born in Bergamo November 12, 1928) is an italian scientist, pharmacology research scientist, physician and professor in chemotherapy and pharmacology and director of the Mario Negri Institute for Pharmacological Research.
Chinese Medical Herbology and Pharmacology is a text on Chinese herbology by Dr. John K. Chen and Tina T. Chen.
 It is one of the few comprehensive texts on Chinese herbology in existence that has been published in the English and German language, and it is widely recognized by the oriental medicine community as both a valid teaching tool used in many oriental medicine universities in the US, as well as a reference book that is widely cited by many academic individuals and practitioners.
 In addition to the traditional and modern uses of Chinese herbology, this text is also a tremendous source that details clinical studies and research, safety data and toxicology, as well as western pharmacological and herb-drug interactions.
 This text is also part of the required knowledge from the national (NCCAOM) as well as many state Acupuncture licensing boards.
 It has been and continues to be cited in many published articles and papers on Chinese Herbal Medicine, especially those that cover the subject of pharmacological and herbal interactions.

Question: K. K. Chen headed pharmacological research at which global company for 34 years?
