국내에서 말 마취에 관한 보고서는 매우 드물다. 본 연구의 목적은 말임상에서 마취중 폐사율을 알아보기 위하여 2005년 1월부터 2010년 10월까지 부산경남경마공원 동물병원에서 Thoroughbred 경주마를 대상으로 조사하였다. 기간 중 전마취는 detomidine hydrochloride(0.01 mg/kg) 또는 xylazine(0.5 mg/kg)를 사용하였고, 근육이완제는 guaifenesin(50-100 mg/kg)을 사용하였으며, ketamine hydrochloride(2 mg/kg)으로 정맥전신마취를 유도하였고, 그 후 isoflurane(1.3-1.5%)으로 흡입마취를 유지하였다. 190 마리 중 각각 150 마리가 흡입마취를, 40 마리가 정맥마취를 받았다. 마취 목적은 근골격계 장애를 위한 수술이 가장 흔하였고 다음으로는 비뇨기계와 호흡기계 순이었다. 마취에 의한 폐사는 골편을 제거하기 위한 관절경수술을 받는 경우에서 한 건이 있었다. 마취시간은 150 분이었으며 사인은 마취기계 미숙에 의한 저산소증이었다. 결론적으로 Thoroughbred 경주마의 마취중 폐사율은 0.52%로 나타났다.

제주마의 세 구룹의 집단(group I , 제주도축산진홍원 관리마; group Il , 농가사육마; group III, 제주경마장의 경주마)과 외래품종인 Thoroughbred, Mongolian horse 및 Quarter horse에 있어서 transfemin 유전자 분포를 비교하기 위하여 Transferrin 유전자 exon 13, 15 및 16에 대하여 SSCP 분석을 수행하였다. 조사된 유전자의 빈도는 집단간의 유전적 분화거리를 측정하는데 이용되었고 집단분화의 유의성을 검정하였다. 집단분화를 나타내는 Fst 값에 의하면 제주마 group I 은 group Il (0.067) 및 group III(0.070)와는 가깝게 위치하고 있었으나 Mongol 집단과는 0.091 로， Thoroughbred 집단과는 0.189의 유전적으로 거리가 다소 먼 분화된 집단관계를 보여주고 있었다. 또한 제주마 group I 은 외래품종인 Thoroughbred, Mongolian horse, American Quarter 집단뿐만 아니라 제주마 group Il 및 m와도 차별화 되는 집단으로 유지되고 있음을 보여주고 있었다'(p <0.05). 제주 경마장에 경주마로 이용되고 있는 제주마 group ill는 제주마 group I 및 Thoroughbred 품종집단에 대해서 칩단분화에 유의성이 안정 ( p < 0.01)되 었고 나머지 다른 집단과는 집단분화의 유의성이 없었다(p > 0.05). 제주마 group Il, group Ill 및 몽고마 사이에는 분화 확률의 유의성이 없어서 이들 집단간에는 유전자 빈도가 매우 유사한 것으로 생각되었다. 이로서 비교적 짧은 기간에 번식환경의 격려 또는 외래품종의 유전자 유업에 의하여 제주마의 transferrin 유전자 빈도는 제주마 집단간에 이질화를 초래하고 있으며， 집단의 분화가 유전자의 유엽이 원인이라면 혈통보존되는 축산 진홍원의 관리집단 이외의 제주마 집단은 외래 품종의 유전자 유업으로 제주마의 고유한 유전적 특성이 빠른 속도로 희석될 것으로 생각된다.

A chronic wasting disease in a 10-month-old Thoroughbred filly is described. The filly presented with chronic colic, which was charactered by progressive loss of weight. Over a period of a couple of days the filly suffered from serious colic and subsequently. Post-mortem examination revealed the cecocolic intussusception as a total invagination of the cecum into the right ventral colon. It seems logical to assume this invagination occurred at the start of the illness. In addition, there were also Anoplocephalar perfoliata in the cecum and the right ventral colon.

This study was carried out to investigate the blood groups(Aa, Ca, Dc, Qa, Ua) and antierythrocyte antibody associated with neonatal isoerythrolysis(NI) in Thoroughbred horses. The blood groups from 1,351(35 stallions, 1,316 mares) Thoroughbred horses tested by serological procedures, and antierythrocyte antibody from 52 mares by indirect antiglobulin test. The blood groups(factor) of Aa, Ca, Dc, Qa and Ua positive were 97.1%, 100%, 91.4%, 82.9%, and 17.1% in stallions, respectively, and were negative 3.5%, 6.2%, 25.1%, 18.3%, and 77.1% in mares, respectively. These mares are considered to be at risk for production of an NI foals. The antierythrocyte antibody was not detected by this technique in all mares. These results suggest that the all breeding mares without blood groups Aa(3.5%) and Qa(18.3%) should be selected a appropriate stallion to prevent of neonatal isretythrolysis during the breeding season in Thoroughbred horses.

A 3-year-old female Thoroughbred racehorse was presented following the accidental oral and skin administration of amitraz. This case report describes the clinical signs and the treatment of this horse. Clinical signs of amitraz toxicosis are associated with the stimulation of alpha2-adrenergic receptors. Amitraz is seldom fatal because the effects can be reversed by alpha2-adrenergic antagonists. The horse displayed typical clinical signs of colic, including pawing, small hard drops, tranquillisation, depression, ataxia, muscular incoordination and impaction colic lasting up to 7 days. The syndrome was accompanied by mild dehydration. The horse survived after persistent symptomatic treatment, including the giving of intravenous fluids, antibiotics, multiple doses of mineral oil per os, nonsteroidal anti-inflammatory drugs and dexamethasone intramuscularly and intravenously.

A 1-year and 8-month-old male, thoroughbred horse showed fever ($39.8^{\circ}C$), cardiac murmur, tachycardia up to 80 beats/min, anorexia, depression and lameness for about 2 months. The dead horse was referred to pathology laboratory at the College of Veterinary Medicine in Jeju National University. At necropsy, Severe protruding multiple rough cauliflower-like yellowish red nodules ranged $5{\sim}6{\times}2{\sim}3cm$ in size were attached on the mitral valve of the left heart. A yellowish red long stick-shaped thrombus $15{\times}3.5{\times}1.5cm$ in size was also present inside the right ventricle. Multifocal infarcts were scattered in the myocardium and renal cortex. Histopathologic examination revealed that morphologic diagnosis were vegetative endocarditis, thrombus in right ventricle, infarcts in myocardium and kidney, pulmonary congestion and edema, and splenic congestion. The isolated bacteria from vegetative lesions and thrombus were confirmed as Escherichia (E.) coli based on the bacterial culture and VITEK 2 system. Based on the gross and histopathologic features, and bacterial test, this case was diagnosed as vegetative endocarditis with thrombus formation associated by E. coli in a thoroughbred horse.

The disease causing colic is the greatest cause of death in the domestic horse population today and accidental deaths as a result of colic leads to decreased productivity and economic losses in the horse breeding industry. Large colon impaction is the most common cause of colic in horses. Horses may ingest sand either by eating from the ground in sandy locations, or because of its inclusion in hay. In certain areas sand impaction is relatively common. The horse (4 year, female) presented with abdominal pain, which was charactered by willing to lie down, pawing, and looking at flank. A month later, the horse died suddenly at sand paddock. Post-mortem examination revealed the sand impaction as a lot of feces, sand and gravels in the right dorsal colon. In addition, there was necrosis and debilitation in mucosal lining of the large colon and rupture site on the right dorsal colon. The purpose of this article is to review sand impaction and emergencies in Thoroughbred horses.

In this report, we described a case of acute colic with uterine rupture in a Thoroughbred broodmare during parturition. A 14-year-old broodmare showed acute colic characterized by rolling just after delivering of a healthy foal. Large intestine was prolapsed through vulva, contaminated with soil and its serosa was heavily damaged. We performed a euthanasia according to the owner's request. Post mortem examination revealed about 15 cm rupture on ventral side of the uterus. In addition, the orphan foal follow his owner after necropsy on his dam.

A variety of enteric deseases may result in the manifestation of abdominal pain in horse. An acute colic in a 5-month-old Thoroughbred filly is described. The filly was presented with acute colic characterized by rolling and pawing. Next day she suffered from severe abdominal pain and subsequently died. Post mortem examination revealed very heavy ascarid, Parascaris equorum (P. equrum) infection in cmall intestine. In addition, it is also noted the presence of P. equorum in the stomach. Infection due to P. equorummanifests itself in foals between 6-8weeks and one year of age. P. equorum is a common and ubiquitous parasite that persists for many years in stables and on pasture in spite of good hygiene and anthelmintic control programs.

A 4-year-old Thoroughbred mare was brought to the Korea Racing Authority Equine Hospital with heightened sensitivity to touch of the hindquarter, reluctance to step forward, frequent urination even during training, clitoral winking, tail swinging, tail lifting, and training difficulties due to being in constant heat. The trainer claimed that she was in heat and exhibited reduced performance. Physical and lameness examinations revealed no abnormality. Rectal palpation and transrectal ultrasonography revealed normal reproductive organs and estrus. As she exhibited typical estrous behavior without any other physical conditions, the mare was considered to express undesirable estrous behavior. An intrauterine glass ball was inserted into the mare on ovulation day. However, the estrous behaviors were reduced unsatisfactorily. Additionally, 1 mL of peanut oil was administered on the 10th day after the intrauterine device insertion. The mare returned to training and expressed no undesirable estrous behavior over 30 days after the peanut oil treatment. However, further follow-ups were not conduct as the mare was retired to a farm after a limb injury occurred during training. This is the first report of undesirable estrous behavior in a Thoroughbred mare under the rules of racing in Korea. It is recommended that equine clinicians in Korea consider peanut oil as a therapeutic agent to control mares' estrous behavior-related problems.
