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.

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.

Furosemide is a potent diuretic used in the horse for the prophylaxis of exercise-induced pulmonary hemorrhage(EIPH), and in a variety of clinical condition. The purpose of this study was to set up the effect of furosemide in Thoroughbred horses, and to examine the time of maximal effect of furosemide to prevent the EIPH. The animals of the experiment were 4 Thoroughbred racing horses(female, average 6 yrs, BW $507{\pm}80.2kg$) in Jeju stud farm and the experiment was cross-over design between furosemide(1 mg/kg IV) and normal saline(0.1 ml/kg, IV) administration. We investigated the changes of clinical signs(body weight, skin turgor, capillary refilling time, jugular distensibility), CBC(PCV RBC), serum chemistry(TP, AST, GGT, glucose, LDH, BUN and creatinine) and electrolytes ($Na^+,\;K^+,\;Cl^-,\;Ca^{2+}$) on 0, 30 mins, 1, 2, 4, 8 and 24 hrs in furosemide and saline administration roup, respectively. The weight decreased significantly(P<0.05) in 4 hrs after furosemide treatment, but skin turgor, CRT, jugular distensibility remained unchanged throughout the experimental period. RBC and PCV decreased after furosemide administration but soon recovered. TP increased to the highest level in 30 mins after furosemide administration and recovered in 8 hrs. Furosemide administration resulted in increases in glucose, AST, GGT, LDH, BUN, creatinine(P<0.05) and decreases in $Ca^{2+},\;Na^+,\;K^+,\;Cl^-$ (P<0.05). All of values were within normal range throughout the experimental period. There was the alteration of blood and serum chemistry after furosemide administration, all of values were within normal range. And the best time of furosemide administration will be 30 minutes before the racing in order to preventing EIPH.

A 45-year-old man presented with dyspnea and hemoptysis during exercise. A chest computed tomography (CT) revealed multifocal diffuse patchy ground glass opacity and interlobular septal thickening in both the lungs. Permeability pulmonary edema or pulmonary hemorrhage was suspected. Serologic studies for autoimmune disorders and vasculitis were negative. There was no laboratory evidence of coagulopathy, other hematopoietic disease or infectious disease. Considering correlation with exercise, we diagnosed exercise-induced pulmonary hemorrhage (EIPH) or exercise-induced pulmonary edema (EIPE). The patient was managed with antifibrinolytics, antibiotics, and antitussive agent. After a week, follow-up chest CT revealed completely resolved pulmonary hemorrhage. About 2 months after the first event, he visited again with dyspnea and hemoptysis during running. In the present study, we report a case of recurrent pulmonary hemorrhage after exercise.
