Purpose: The role for minimally invasive surgery in chest trauma is vague, one that recently is more frequently performed, and one attractive option to be considered. Thoracoscopic surgery may improve morbidity, mortality, hasten recovery and shorten hospital stay. Methods: A total of 31 patients underwent video assisted thoracoscopic surgery for the treatment of blunt and penetrating chest trauma from June 9th, 2013 to March 21st, 2016 in Jeju, South Korea. Results: Twenty-three patients were males and eight patients were females. Their ages ranged from 23 to 81 years. The cause of injury was due to traffic accident in 17 patients, fall down in 5 patients, bicycle accident in 2 patients, battery in 2 patients, crushing injury in 2 patients, and slip down, kicked by horse, and stab wound in one patient each. Video assisted thoracoscopic exploration was performed in the 18 patients with flail chest or greater than 3 displaced ribs. The thoracoscopic procedures done were hematoma evacuation in 13 patients, partial rib fragment excision in 9 patients, lung suture in 5 patients, bleeding control (ligation or electrocautery) in 3 patients with massive hemothorax, diaphragmatic repair in two patients, wedge resection in two patients and decortication in 1 patient. There was only one patient with conversion to open thoracotomy. Conclusion: There is a broad range of procedures that can be done by thoracoscopic surgery and a painful thoracotomy incision can be avoided. Thoracoscopic surgery can be done safely and swiftly in the trauma patient.

A 5 day-old Warmblood foal was presented with a quarter crack due to the dam accidentally stepping on his left hind foot. Physical examination revealed the vertical crack included the coronary band of the medial side of the left hind hoof (quarter crack) with the lower pastern avulsion wound. Different from adult horses, the foot of the 5 day-old foal lacked adequate hoof wall thickness for stainless steel wire insertion and hoof size for a reinforcing fabric to be applied. Therefore, the authors decided to stabilize the edges of the cracked wall only by the polymethyl methacrylate (PMMA) composites without wiring and a reinforcing fabric application; and gluing a plastic shoe that was reshaped to protect the lower pastern and to spread pressure to other parts of the hoof when bearing weight. Disinfection and a supportive bandage were applied daily for 2 weeks. A month after the hoof crack accident, lameness had diminished. The quarter crack in this foal was treated successfully by the application of the composites three times with a reshaped gluing shoe, with approximately a month interval over the 4 months. After 4 months, it presented a successful functional recovery and needed no further treatment. When followed up 8 months after the accident, it revealed successful outcomes without hoof shape distortion and unbalanced hoof/limb growth.

The autonomic regulation of heart rate (HR) is an indicator of the body's ability to adapt to an exercise stimulus. However, there are no reports on this topic in relation to Jeju horses used for racing. The aim of this study was to analyze the HR responses of Jeju horses during race trials and to investigate the correlation between HR and performance in these horses. HR data were collected from 17 healthy 2- to 7-year-old Jeju horses wearing HR monitors during race trials. Pearson correlation coefficients was used to determine the significance of the association between the race trial time and HR. A significant inverse correlation was observed between the race trial time (performance) and both the maximal HR (HRmax, r = -0.69, p < 0.01) and HR reserve (HRR) (HRmax - average HR during the warm-up period, r = -0.63, p < 0.01) and between the HRR and HRmax (r = 0.73, p < 0.01). Horses with a lower average HR during the warm-up period and higher heart rates during the trial achieved faster race trial times. This study reports the first HR measurements in Jeju horses during race trials, providing new insights into the HR response of this breed to exercise. The use of a noninvasive remote HR monitor system allowed assessment of exercise responses in the field, and the results suggest that both the HRR during warm-up period and HRmax may be useful performance indicators in Jeju horses.

The aim of the study was to investigate the seroprevalence of equine herpesvirus type 1 (EHV-1) and type 4 (EHV-4), equine influenza virus (EIV), and Streptococcus (S.) equi subspecies equi in the horse population of Jeju. Serum samples were taken from 71 horses, regularly vaccinated with EHV-1 and strangles twice (April and November) a year. In April 2014, seropositive rates of EHV-1 and strangles were 24.5% and 84.5%, while in November, were 26.8% and 62.0%, respectively. A total of 1,144 serum samples, including Jeju native horses, Halla horses, and Thoroughbred horses were collected from slaughter house for 4 years (2014 to 2017) and it is unclear the animals were vaccinated or not. The seropositive rates in Jeju was 21.9% (250/l,144) for EHV-1, 96.4% (1,103/1,144) for EHV-4, 14.6% (129/882) for EIV, and 79.3% (879/1,108) for strangles. The seropositive rate was the highest in Thoroughbred, but lowest in Hala horse.

제주마는 한국의 말 품종으로 제주도에서 오랜 기간 자생하여 왔다. 제주마의 기원은 몽골마에서 유래한 것으로 추정되었다. 그러나 최근 연구에서 제주마와 몽골 토종마를 비교 한 결과, 유전적으로 가까우나 제주마가 몽고마와 독립적으로 진화해 온 것으로 보고되었다. 제주마는 경주마로 이용되어 경주 능력이 주요한 경제 형질로 활용되고 있다. Myostatin (MSTN) 유전자는 다양한 포유류에서 골격근량에 영향을 미치는 것으로 연구되었다. Thoroughbred에서 MSTN 유전자 내 존재하는 변이가 경주 능력 및 스태미너에 영향을 미치는 것으로 알려져 있다. 우리는 제주마 1,433두를 포함하여 여러 말 품종의 MSTN 유전자내 변이 빈도를 비교하였다. MSTN 유전자의 g.66493737 변이 중 장거리 적성 유전자형(TT)의 경우 제주마에서 빈도가 0.826으로 한라마(0.285) 및 Thoroughbred (0.252)보다 높은 것으로 확인되었다. 또한 다른 연구를 참고하여 8종 말에서 g.66493737 빈도를 비교하였다. 그 결과, 경주마로 활용되는 품종은 CC형의 빈도가 높았으나, TT형의 빈도는 낮은 것으로 확인되었다. 반대로 승용마 및 역용마 등의 품종은 TT형의 빈도가 높은 것으로 확인되었다. 제주마의 경주 거리(400 m, 800 m, 900 m, 1,000 m, 1,110 m, 1,200 m)별로 유전자형과 도착 기록을 비교 분석했다. 그 결과 1,000 m 이하의 경주에서는 CT형이 TT형보다 더 빠른 도달 기록을 보였다. 그러나 1,110 m 이상의 경주에서는 거의 동일한 결과가 확인되었다. 본 연구에서는 제주마의 MSTN 유전자 변이가 경주 거리 적성과 관련이 있을 수 있음을 시사하였다. 이러한 결과는 추후 연구를 통해 제주마에서 경주 거리 적성 및 경주 능력과 연관된 마커 개발을 위한 자료로 활용이 가능할 것으로 사료된다.
