Differences of meat qualities between Japanese Black and Holstein have been known in Japan, however, the causative proteins and/or the genetic background have been unclear. The aim of this study was to identify candidate proteins causing differences of the meat qualities between the two breeds. Using technique of two-dimensional gel electrophoresis, protein profiling was compared from samples of the longissimus dorsi muscle and subcutaneous adipose tissue. Five protein spots were observed with different expression levels between breeds. By using LC-MS/MS analysis and Mascot program, three of them were identified as ankyrin repeat protein 2, phosphoylated myosin light chain 2 and mimecan protein. Subsequently, we compared the DNA coding sequences of three proteins between breeds to find any nucleotide substitution. However, there was no notable mutation which could affect pI or molecular mass of the proteins. The identified proteins may be responsible for different characteristics of the meat qualities between Japanese Black and Holstein cattle.

흰쥐 우측요부에 RK3E-ras cell주입으로 7일 이내에 종양이 발달하는 것을 관찰하고, 단삼 추출물을 제조하여 항종양 효과를 관찰하고자 1주 후부터 2주 동안 육종 부위에 투여 후 종양의 크기와 무게를 측정하고 조직학적인 관찰을 통하여 암세포의 발달과 암전이 유무를 살펴보았다. 암종의 크기는 대조군에 비하여 단삼 추출물을 투여한 실험군에서 현저히 감소(p<0.01)하였으며, 암종의 중량 또한 실험군에서 현저히 감소(p<0.01)하였다. 조직학적 관찰 결과 종양을 둘러싸고 있는 섬유막은 대조군에 비하여 실험군에서 발달 해 있었으며, 암세포의 밀도는 실험군에 비하여 대조군에서 높았다. 간조직을 관찰한 결과 대조군의 간문맥 주변에서 전이된 것으로 보이는 암세포들이 다수 관찰되었다. 이와 같은 결과를 토대로 단삼 추출물이 항종양효과가 있다고 사료된다.

외상성, 혹은 선천적 결손으로 인한 함몰부에 사용한 자가 유리지방 이식은 잘 알려진 방법이다. 이를 위해 사용되는 주된 공여부는 복부나 둔부의 피하지방이었다. 그러나, 1977 년 Egyedi는 협지방대를 유경피판으로 처음 사용하였다. 협지방대는 안면골 절단술시, 협측 피판을 들어올릴 때, 혹은 이하선관 수술 같은 구강내 수술시 항상 귀찮은 구조물로써, 수술 시야를 방해한다. 협지방대는 매우 세밀한 막으로 둘러싸인 소엽형태의 볼록한 물질로, body와 네 개의 prccess들로 구성된다. 이 돌기들은 여러 근육층 사이의 충전물로 작용하며, 유아에서는 sucking시 보조작용으로, 성인에서는 윤활재로 사용되기도 한다. 본 교실에서는 협지방대를 사용하여 세 증례의 협골 함몰부에, 그리고 한 증례의 비순구 재건을 위해 사용한 바, 양호한 결과를 얻었기에 문헌고찰과 함께 증례보고를 하는 바이다.

Osteomas are benign, slow-growing osteogenic lesions frequently found in the craniomaxillofacial region. They can be classified as peripheral, central, or extraskeletal. Reactive mechanisms to trauma or infection, as well as muscle traction, are thought to play a major role in the development of peripheral osteomas. In the present report, a 41-year-old woman presented with a slowgrowing, painless mass on her left eyebrow. She had suffered trauma 15 years prior. In the computed tomography scan, a 2.5×2×0.7-cm radio-opaque tumor was detected just medial to the left supraorbital foramen, and a peripheral osteoma was clinically diagnosed. An elective operation under general anesthesia was planned. Following a suprabrow incision, subcutaneous and intramuscular dissection was performed. In the surgical plane deep to the corrugator muscles and superficial to periosteum, a branch of the supratrochlear nerve was encountered and preserved using a vessel loop. The osteoma beneath the periosteum was extracted in multiple fragments using a chisel and mallet to minimize trauma to the nerve. Contour and facial symmetry were corrected. To use a suprabrow incision, the surgeon must understand neighboring anatomical structures, including the course of the supratrochlear and supraorbital neurovascular bundles. When these structures are located adjacent to tumor lesions, careful surgical maneuvers should be performed to preserve them.

말초 신경 조직에서 발생되는 종양은 신경섬유종, 신경초종, 파립세포종, 악성신경초종 등이 있다. 신경섬유종은 2가지 형태로 분류될 수 있다. 첫째 형태는 단독형 신경섬유종이고, 둘째는 신경섬유종 혹은 Von Recklinghausen's병으로 불리우는데 이는 주로 피부, 신경조직, 뼈, 연조직에 기형을 유발할 수 있고, 선천적이며, 가족력을 나타낸다. 단독형 신경섬유종은 양성이며, 경계는 명확하나 capsule에 의해 싸여 있지 않으며, 피부나 피하조직에 sessile 혹은 pedunculated 형태로 나타난다. 두경부의 어느 부위에나 나타날 수 있으며, 구강내의 호발 부위는 혀, 협점막, 구개 순이다. 단독형 신경섬유종은 방사선에 의한 치료에 효과가 적으며, 재발율이 낮고, 치료는 주로 외과적 절제술로 제거를 하고, 결손부를 삼각흉피판(D-P flap)과 설피판(tongue flap)으로 수복하여 현재까지 합병증 없이 양호한 결과를 얻었다.

Background Venous thromboembolism, a spectrum of diseases ranging from deep venous thrombosis to pulmonary embolism, is a major source of morbidity and mortality. The majority of cases described in plastic surgery involve abdominoplasty. Risk assessment and prophylaxis are paramount in such patients. General recommendations were recently developed, but the evidence in the literature was insufficient to prepare exhaustive guidelines regarding the medication, dosage, timing, or length of the prophylaxis. Methods A thromboprophylaxis protocol was developed for patients undergoing abdominoplasty. The protocol consisted of preoperative, intraoperative, and postoperative measures. Enoxaparin was administered as chemoprophylaxis in selected patients. The study involved 253 patients. The patients were analyzed for age, body mass index, enoxaparin dosage, risk factors, and complications. Results Deep venous thrombosis was documented in two cases (0.8%). No pulmonary embolism occurred. Three patients (1.2%) presented mild subcutaneous abdominal hematoma within the first postoperative week that spontaneously resorbed with neither aesthetic nor functional complications. Two patients (0.8%) presented severe hematoma requiring surgical re-intervention for drainage and hemostasis revision. Statistical analysis showed no significant correlation between enoxaparin dosage and hematoma (P=0.18) or deep venous thrombosis (P=0.61). Conclusions The described thromboprophylaxis protocol proved to be effective in the prevention of thrombotic events, with an acceptable risk of hemorrhagic complications. Furthermore, it provides new evidence regarding the currently debated variables of chemoprophylaxis, namely type, dosage, timing, and length.

Objectives : Our purpose of this study was to evaluate the association between abdominal adipose tissue and oriental obesity pattern identification. Methods : This study was performed in 78 healthy obese(BMI(body mass index)${\geq}25kg/m^2$) women in Seoul. Subjects underwent abdominal CT(computed tomography) scanning and were asked to complete the oriental obesity pattern identification questionnaire. Subjects were given written consent and this study was performed under permission of institutional review board of Kyung-hee East-west Neo medical center. Results : 1. VFA(visceral fat area) and VSR(visceral/subcutaneous adipose tissue ratio) were significantly correlated with stagnation of the liver qi(肝鬱, gan-yu)(p<0.05). But, other patterns were not significantly correlated with oriental obesity pattern identification(p>0.05). 2. We evaluated a difference of oriental obesity pattern identification score in visceral obesity group(n=34) versus non-visceral obesity group(n=44). Scores of all patterns except food accumulation(食積, shi-ji) were significantly higher in the visceral obesity group than in the non-visceral obesity group(p<0.05). Especially, there was a further significant difference in stagnation of the liver qi(肝鬱, gan-yu)(p<0.01). Conclusions : Generally, the stagnation of the liver qi(肝鬱, gan-yu) has a close relation with stress and depression. This study suggests that stress and depression might be correlated with visceral fat, and the use of oriental obesity pattern identification would be helpful for planning a treatment schedule of visceral obesity in the clinic.

Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is an ulcerative lesion on oral mucosa featuring as a benign mass of self-limiting growth. It can be easily misdiagnosed as squamous cell carcinoma (SCC) due to its long healing period and elevated or rolled-up margin. A 57-year old male patient who visited our department was diagnosed as SCC according to the clinical features, results of positron emission tomography (PET) and magnetic resonance imaging (MRI) of the oral lesion. However, after performing incisional biopsy, histopathologically, there were no atypical cells, but eosinophil and CD 30+ T-cells were clustered in subcutaneous and muscle tissue. It is very significant to consider this reactive lesion in the field of oral and maxillofacial surgery because of its possibility of mistaken as malignant disease. Here, we will report a couple of cases of TUGSE with references and limit of radiographic tools used for diagnosis of head and neck cancer.

Purpose: The standard treatment of esophageal cancer is the Ivor-Lewis operation, which consists of an abdominal phase involving gastric tube formation, and a chest phase involving esophagectomy and anastomosis. We aimed to report our experience of performing thoracic esophagectomy with the laparoscopic gastric pull up (LGPU) technique and its surgical outcomes. Methods: Clinicopathologic data and short-term surgical outcomes of 14 patients who underwent LGPU for thoracic esophageal cancer from August 2008 to May 2016 were retrospectively reviewed. Results: Mean age of the patients was 62.3 years and mean body mass index was $21.7kg/m^2$. Eleven patients had medical comorbidities. Patients' mean American Society of Anesthesiologists score was 2. Mean operation time was 428.5 minutes, with the mean abdominal operation time being 138.9 minutes. There was no open conversion case. Three patients had pneumonia, three patients had surgical site infection, and one patient had subcutaneous emphysema within 30 days after surgery. One patient had minor anastomosis site leakage. There was one 30-day mortality case. One patient with postoperative aspiration pneumonia developed acute respiratory distress disease, and died due to sepsis. Mean postoperative intensive care unit stay was 3.5 days, and mean postoperative hospital stay was 20.6 days. Nasogastric tubes were removed on average at 3.4 days, and mean oral intake time was 3.4 days. Conclusion: If the gastrointestinal surgeon has extensive experience in laparoscopic procedures, LGPU will be a safe and feasible technique for thoracic esophagectomy in patients with intrathoracic esophageal cancer.

Purpose: Weight loss and deterioration in body composition are observed in patients with gastric cancer (GC) following gastrectomy. This study aimed to investigate the impact of residual stomach volume (RSV) on the nutritional status and body composition of patients with GC treated with distal gastrectomy. Materials and Methods: In total, 227 patients who underwent minimally invasive distal gastrectomy with Billroth 1 anastomosis for stage I GC between February 2015 and May 2018 were enrolled. Clinicodemographic and laboratory data were collected from the GC registry. The RSV, abdominal muscle area, and subcutaneous/visceral fat areas were measured using computed tomography data. Results: A larger RSV was associated with a lower decrease in the nutritional risk index (P=0.004) and hemoglobin level (P=0.003) during the first 3 months after surgery, and better recovery at 12 months. A larger RSV demonstrated an advantage in the preservation of abdominal muscle area (P=0.02) and visceral fat (P=0.04) after surgery, as well as less reduction in weight (P=0.02) and body mass index (P=0.03). Conclusions: Larger RSV was associated with improved nutritional status and better preservation of muscle and fat after distal gastrectomy.
