Biographical Sketch

Thomas Tobin (TT), Veterinarian, Dublin, 64, Pharmacologist MSc, Guelph, 66, PhD, Toronto, 70, faculty, Michigan State University, Equine Pharmacology, Therapeutics and Toxicology program at the University of Kentucky, 75-date. In 1979 organized the Third Int.Symp.on Equine Medication Control, in 1981 published Drugs and the Performance Horse, 500 page text. In 1983 testified before Congress on the “Corrupt Horse Racing Practices Act”; thereafter, activity on this bill ceased.

In 1980 became a Diplomate of the America Board of Toxicology. In 1985 he began research that introduced ELISA testing to horse racing. Licensing and commercialization of this technology led to the creation of WTT ELISA TESTS, later sold to Neogen Corp ( Neogen Lexington now employs 100, brings in $30M/year and an ongoing significant royalty to UK.

In 1988 became Director of the UK Graduate Center for Toxicology, developed minority programs and brought in a $800K NIEHS Training Grant. By 93 core faculty and student admissions were up three-fold, extramural funding had increased from 0 to $800K per year, and courses on “Ethics in Scientific Research” and “Risk Assessment” had been developed. When NRC reviewed Kentucky doctoral programs in 93, only The Graduate Center for Toxicology was rated “extremely effective.”

In 1994, TT organized an international workshop, “Testing for Therapeutic Medications, Environmental and Dietary Substances in Racing Horses,” that brought 70 industry leaders to Lexington. In 1995, TT and colleagues organized “The Commission Veterinarian/Equine Medical Director: A Short Course”. In 1995, TT and colleagues founded the Testing Integrity Program (TIP) that serves as a national drug testing Quality Assurance Program. TT was named “Man of the Year” in 1995 by the National Horsemen's Benevolent and Protective Association.

In 1996, TT and David Granstrom investigated new therapeutic approaches to Equine Protozoal Myelitis (EPM) rapidly establishing the therapeutic efficacy of diclazuril and toltrazuril. A patent in this area was granted (#5,883,095, 1999) and licensed to Bayer Animal Health; in July 2001, Bayer Marquis® (toltrazuril sulfone, was the first FDA-approved treatment for EPM and brings in a significant royalty to UK.

In 1998 the industry became focused on clenbuterol. A series of LC-MS-MS based studies led to publication of a highly sensitive serum test for clenbuterol, allowing much more sensitive and reliable regulatory control of therapeutic medications than previously possible. In 1998 TT also organized and published a TIP seminar on furosemide.

In 2000, at the direction of the Kentucky Racing Commission (KRC), TT developed a series of nationally accredited continuing education short courses for veterinary practitioners and regulatory veterinarians in Kentucky and surrounding states. Six short courses were offered.

In May of 2001, TT chaired the Toxicology Working Group investigating the spring 2001 Mare Reproductive Loss Syndrome (MRLS), and his research group was temporarily redirected to work on MRLS. Within three weeks the Eastern Tent Caterpillar was identified as the most likely cause of MRLS. Work in spring 2002 clearly linked MRLS to the Eastern Tent Caterpillar; in August 2002, TT and David Powell organized the first workshop on the Mare Reproductive Loss Syndrome, published in May 2003. In 2003 LFL/MRLS was shown to follow an unusual probabilistic model, Accelerated Failure Time analysis, and a biologically unique pathogenesis for MRLS ( based on septic penetrating setal fragments was proposed.

In 2003 the program contributed to the writing of the National HBPA Proposed Policy on Drug Testing and Therapeutic Medication ( and has since focused on developing fully validated analytical methods for agents abused in racing horses. In June of 2003 it was decided that it would be in the best interests of the racing industry in Kentucky for the program to accredit, and the process of becoming A2LA accredited was initiated.

In 2004 the program was redirected to emphasize new therapeutics and toxicology, with an emphasis on equine diagnostics, prophylaxes and therapeutics. In 2005, the program began synthesizing series of deuterated internal standards for equine therapeutic medications; in July 2006, US Patent # 7,074,843 for a novel veterinary sedative and tranquilizer was awarded and a unique pathogenesis for oligofructan based laminitis was proposed.
