During the 5 years period(93-197) of Seoul racecourse Thoroughbred racing, 2i963 holies took an active part in Seoul Racecourse and 61,181 horses entered the racing.400 horses(305 : 1 time, 76 :2 times, 19 :3 times, total : 514 cases) had bled(EIPH) from their nostils after their races. Incidence of bleeding horses from the 21963 racehorses was 13.5%, and incidence of bleeding cases from the 61,181 horses was 0.84%. The average racing frequence (1.05 times/1 month) of bleeders was more than that(0.8 times/1 month) of total race-horses. There was tendency to higher incidence of bleeding at older in age, female in sex, England/ Ireland horses in origin, higher grade in performances heavier in body weight increased, larger in weight to be carried, mid or longer in racing distance, handicap race, spring in season. Relationship did not exist between bleeding and respiratory disease. These results suggested that frequent entering into the race should be controlled. And body weight regulation with conditioning is recommended far reducing incidence of EIPH. It is supposed to prevent bleeding that decrescent performance horses should not be entering long distance or handicap race.

This study was carried out to investigate the characteristics of 335 injured racehorses that had rested over 6 months or were retired in Seoul racecourse from 1994 to 1998. We surveyed 62,117 racing horses and incidence rate of injured horses was 0.54%. Of 335 horses, 322 horses(96.1 %) were associated with musculoskeletal disorders. The musculoskeletal disorders observed with high incidence were fracture and luxation(53.1%), tendinitis and desmitis(17.7%) in category, forelimb(92.5%) in location, below metacarpus/metatarsus(73.0%) in lesion. The prevalence rate of male, 5 years old or Ireland origin was higher than any other individual. These data would be useful standard reference for control of injuries in racing horses.

Background: The incidence of colic and the outcomes of colic surgery have not been surveyed in racetracks in Korea. Objectives: This study examined the incidence, mortality, and case fatality of colic and investigated the effects of age and sex after an exploratory celiotomy on the long-term survival rate (return to racing), subsequent racing performance, and career longevity. Methods: The incidence, mortality, and case fatalities of colic were examined over an 11-year period. The records of 40 horses that had undergone a celiotomy, after participating in at least one race and 75 race-matched control horses were analyzed. The racing performance and career length of the horses that returned to racing post-surgery were compared with a control group. Results: The annual incidence, fatality rate of colic, and annual mortality rate at Seoul Racecourse were 6.5, 2.8 per 100 horse-years, and 0.2 deaths cases per 100 horse-years, respectively. Of the 40 horses that underwent colic surgery, 26 (65%) returned to racing. The likelihood of returning to racing decreased with increasing age of the horses, and geldings had a lower probability of returning. While the performance in the five preoperative races between the two groups was not significantly different, a significant decrease in racing performance was observed after the surgery date (p < 0.01). Horses that underwent colic surgery did not show a significant decrease in career length. Conclusions: Surgical treatment for colic at the age of three and four years had a negative impact on the racing performance. On the other hand, there was no significant difference in career longevity between the two groups.

This study was undertaken to investigate the effect of exercise induced pulmonary hemorrhage(EIPH) on the finishing position of racehorses, 400 bleeders(305: 1 time, 76: 2 times, 19: 3 times, total: 514 cases) which had bled(EIPH) from their nostrils after their races at the Seoul racecourse during the 5 years period('93-'97) were analyzed for this study. The ratio of bleeders to total racehorses in finishing position 1-3,4-6, 7-9 or above 10 was 0.55, 0.84, 0.90 or 1.13%, respectively. There is tendency to higher incidence of bleeding in the later positioned racehorses group. To analyze the correlation between EIPH and finishing position, finishing potion of each EIPHed horses' was checked at 7 successive races(3 races each before/after EIPH. The average final position at the -3rd race, -2nd racer -lst racer EIPHed race, 1st race,2nd race and 3rd race of each bleeder was 5.85. 5.94, 6.21, 7.32, 7.20, 6.51 and 6.53, respectively. Raring times were adjusted to 1,000 m equivalent. Average racing times of the -3rd race,-2nd racer -lst raced EIPHed race, 1st race, 2nd race and 3rd race of each bleeder was 67.1, 67.1, 67.2, 67.6, 67.5, 67.4 and 67.3 second, respectively. Bleeders which finished the race within 1 second following the winners were 25. 3% of total bleeders. The rest 74.7% reached at the finish line 1 second later than the winners. Particularly 46.3% of bleeders were above 2 second later. Therefore this study suggested that bleeding has effect on performance of the racehorse, consequently it make bleeders be placed later positions.

An 18-year-old miniature Appaloosa stallion presented with 6 months of history of sanguineous crusts on medial hind limbs and discomfort of micturition. Cauliflower-like and small masses were treated with cryotherapy for 6 months, but the regrowth of masses occurred. Subsequently, local excision via laser and topical treatment with 5% 5-fluorouracil for 5 months were followed. However, the horse was euthanized 4 months later due to regrowth of the masses. The mass was diagnosed as penile papilloma with cellular atypia and Equus caballus papillomavirus type 2 (EcPV-2) DNA was detected. This is the first report of equine penile neoplasm with EcPV-2 infection in Asia.

This study is about the Korean Jockey's uniform, etc. and horse riding costume as the traditional riding culture grows. I studied informations from the Korea Racing Association's equestrian park, equine museum and Seoul Racecourse Trainers & Jockey's Association. The international regulations of riding costume are compared with Korean regulations, and I consulted some reference books, materials of sports wear and catalogues of some brands regarding horse equipment. The contents includes ; 1. Analysis of informations about horse racing 2. Study of racing, for detail comparative analysis on the following aspects ; -Symbolism, riding costume of jockey, that is, color·pattern·and some formal designs. 3. Suggestion for reasonable and fashionable riding costumes. In the aspects of design, there have not been any historical records, and material adjustments about riding costume in Korea. Therefore we should make more efforts to do developing our traditional costume culture. The result o this study is as follows ; 1. Riding is the sport of etiquette and manners. 2. Most of riding wears are the casual wear centered foreign licenced brands. 3. Study and investment upon specialized material development and processing technology are in demand 4. The need of the consumers are to be satisfied by the quality improvement of the native products design. In addition, we perform to horse racing which is fine play and leisure sports in current society. The horse riding will be a popular sports such as golf, wind surfing, skiing, etc. with the period including lots of kinds of leisure.

The hoof parameters - hoof angle, toe length, heel length, hoof width, hoof length, heel width, hoof circumference - of 1372 Thoroughbred racehorses in Seoul racecourse were measured. Each parameter was compared with the racing time. The parameters were as follows: fore hoof angle $50.1{\pm}0.09^{\circ}$, hind hoof angle $50.1{\pm}0.08^{\circ}$; fore toe fength $82.8{\pm}0.21mm$, hind toe length $88.8{\pm}0.23mm$; fore heel length $28.6{\pm}0.19mm$, hind heel length $24.5{\pm}0.19mm$; fore hoof width $130.9{\pm}0.30mm$, hind hoof width $125.7{\pm}0.28mm$; fore hoof length $133.3{\pm}0.22mm$, hind hoof length $28.1{\pm}0.22mm$; fore heel width $61.2{\pm}0.32mm$, hind heel width $67.9{\p}0.35mm$; fore hoof circumference $264.2{\pm}0.48mm$, hind hoof circumference $253.8{\pm}0.40mm$. Apart from the hoof angle, the hoof parameters increased in proportion to the body weight. The parameters of forelimbs affected the racing time more than those of hindlimbs. The correlation between hoof parameters and racing time was shown more in short-distance race (1000M) than in long-distance race(2200M). The parameters that had correlation with racing time were hoof width, hoof length, heel width of forelimbs and heel width of hindlimbs.

Physiological changes in thoroughbred racehorses during the race were investigated by measuring concentrations of metabolites and exercise-related hormones before and after a race. The conversion point from anaerobic to aerobic exercise during the race was estimated subsequently. Blood samples were taken from the jugular vein of 53 thoroughbreds at different times -three h before and 45 min after- for measuring the concentrations of glucose, non-esterified fatty acids (NEFA), lactate, uric acid, ammonia, insulin, adrenocorticotrophin (ACTH) and cortisol according to the race distance. In accordance with the race distance, each metabolite increased in concentration compared with the level before the race. The level of glucose, in particular, increased from $56.18{\pm}3.20$ mg/dl before the race to $148.82{\pm}8.82$ mg/dl after the race for horses that raced 1,400 m, showing a significant increase of 165% (p<0.001). The concentration of NEFA rose from $76.77{\pm}5.59$ uEq/L to $335.85{\pm}35.39$ uEq/L, up 337% (p<0.01) after a 1,400 m race. Exercise-related hormones also showed similar changes. The level of insulin dropped the most in horses that raced 1,400 m, by 42%, from $0.97{\pm}0.18$ to $0.56{\pm}0.05\;{\mu}g/L$ (p<0.5); however, ACTH and cortisol jumped significantly at 1,800 m, from $20.17{\pm}2.12$ to $551.45{\pm}91.33$ pg/ml (p<0.5) and $1.13{\pm}0.16$ to $5.66{\pm}0.45\;{\mu}g/dl$ (p<0.01), respectively, representing the highest increase. Therefore, based on the changes in glucose, NEFA and insulin levels before and after the race, it was concluded that the race distance of 1,400 m represents the point where racehorses make a conversion from anaerobic to aerobic exercise.

A 14-year-old gelded dressage horse weighing 500 kg was presented to the Equine Medical Center of the Seoul Racecourse of Korea Racing Authority (KRA) due to coughing and mucopurulent nasal discharge. The horse was initiated with empirical antibiotic in the first place. However, the clinical signs did not improve but were rather exacerbated even after 3 weeks of therapy. Extensive diagnostic procedures including transtracheal wash (TTW) fluid cytology were undertaken. The localized wheezes and crackles were auscultated and an increase in the amount of mucopurulent exudate in trachea was observed at endoscopy. Infiltration of neutrophils was observed in the TTW fluid cytology implying chronic obstructive pulmonary disease (COPD). Therefore, the systemic glucocorticoid therapy was to be given for 3 weeks with improved ventilation provided at the same time. The respiratory symptoms started to improve in 7 days of therapy and were fully resolved by when the therapy was terminated. The horse is clinically normal now and being monitored for development of any signs of chronic obstructive pulmonary disease.
