ENPS S Y M P O S I U M FEATURED SPORTS MEDICINE TOPICS
The Equine Nutrition and Physiology Society held their bi-annual Symposium last month in Ontario, California. This was their 14th Symposium. As usual, the papers presented covered a variety of disciplines: Nutrition; Reproduction; Teaching and Extension; Production and Management; and Exercise Physiology. The Symposium this year was especially enhanced by an outstanding group of invited papers by internationally known experts in each of the disciplines. For example, Dr. Peter Wagner, University of California, San Diego, gave an interesting paper on "Determinants of VO~max: Man vs. Horse." The following papers were presented in the exercise physiology portion of the program: 9 Modifications of the third metacarpal bone in young racing Quarter Homes as a result of training; 9 Muscle fiber types in mules and horses; 9Similarities between genders in racing two-year-old Quarter Horses; 9 Kinematic analysis of world championship three-day event horses jumping a cross country drop fence; 9 Blood buffering in intensely exercised miniature horses after intragastric administration of sodium bicarbonate; 9The influence of t rimethylglycine in the trained and untrained horse exercising to fatigue; 9 Plasma aldosterone and electrolyte concentrations in exercising Thoroughbred Horses fed two diets in summer and winter; 9 Electromyographic activity of the gluteus medius muscle and the long digital extensor muscle in the exercising Thoroughbred horse;

concentrations alter exerc=se; 9 Immunophysiology of the race horse; 9 High altitude acclimatization in the horse and mule; 9 Scoring analysis of three world championship three-day events. Non-reviewed Abstracts of the Symposium can be obtained from ENPS, 309 W. Clark Street, Champaign, IL 61820. There were 101 abstracts accepted for the meeting; 77 papers were presented orally, and there were 24 posters. The reviewed Proceedings will be published in the Journal of Equine Veterinary Science this fall. It is estimated that the proceedings will contain about 25 of the best papers.

A highly accurate and stable oxygen analyzer with 0.001% 02 resolution is available from Columbus Instruments. It operates on the principle of magnetic susceptibility of oxygen gas, thus is called the Paramagnetic Oxygen Analyzer. It has the ability to be calibrated in a narrow or extended oxygen percentage range. The full range extends from 0% to 100%, but when high resolution is required the range can be adjusted, for example, from 19% to 21%. To eliminate environmental influences, the sensor itself has a built-in temperature controlled chamber which is also well shielded from external magnetic fields. An air sample pump is built-in as well as a pressure regulator, making Columbus Instruments' Paramagnetic Analyzer immune to both source gas as well as barometric pressure variations. A companion Infrared CO a Analyzer is also available for measuring 02, CO a and CH 4 gases. For more information call Columbus Instruments at: 1-614-276-0861.
Don't forget the 14th Annual Meeting of the Association for Equine Sports Medicine at the Pala Mesa Resort, Fallbrook, CA (North San Diego County). It starts March 10, Friday evening, with a welcome reception. The following morning a group of research abstracts will be presented with emphasis on responses to training. Saturday afternoon sessions feature speakers such as: Dr. William Meyer, Dr. Roy Pool, Dr. Norman Rantanen, Dr. Joyce Harman, and Dr. Sue Stover. The general topic at this afternoon session will be "Diseases of the back and hock." Sunday morning features the topic "Diseases of the equine foot," with emphasis on navicular disease. On Sunday afternoon, there will be wet labs and practical demonstrations. Monday features a full report on recent studies of heat and humidity stress in three-day event horses. Included will be Dr. Catherine Kohn's
