The limitations of food production caused by global warming, consumption of soil fertility, and land shortage have demanded the development of alternative foods. Their market has been increasing, and in particular, there is an urgent need for an alternative meat. Among them, the non-slaughtered cell-cultured meat that can be manufactured in the laboratory, that is, cultured meat, is in the spotlight, which can solve the problem of meat consumption while including the advantages of meat. It is classified into minced cultured meat and structured one with a structure similar to that of real meat. The latter is currently facing limitations related scaffolds, cells, and the multiplicative problems, and many attempts are being made to solve them. The complex problem is related to secure texture and taste as well as structural similarity to actual meat. To solve the problems, it is necessary to lay emphasis on cells, there are fat cells and vascular cells, and the most fundamental cells, muscle cells. These are the main cells that control the texture and nutrients of meat, and unlike other cells, they grow in the form of fibers. A myofibril (also known as a muscle fibril) is a basic rod-like organelle of a muscle cell, which is a quantitatively major component of meat, and one of the tissues that maintain the appearance of the body and bones. In this review article, we focused on the growth of muscle cells into long, tubular cells known as muscle fibers using the fabricated fibrous scaffold, and reviewed not only research results for muscle tissue engineering but also various results in the related fields for the last five years.

Objectives : This study was to investigate the characteristics of the heart rate variability(HRV), types of insomnia and accompanying symptoms of 175 insomnia patients. Methods : For this study we carried out HRV, Inbody of 175 patients with insomnia who have come to Dongeui oriental hospital of Dongeui university from the period of Janaury 2008 to September 2010. We studied the association of the insomnia patients' age and gender with HRV, accompanying symptoms and the types of insomnia. The information of the accompanying symptoms and types of insomnia was based on each patients' progress note. Results : l. There was no significant differences in the characteristics of HRV between male and female. 2. The most frequent symptom shown among the insmonia patents' was headache(41.14%). 3. Comparing the symptoms between the gender, female patients had more dry mouth, alternative periodic chill and fever, and hot flush symptoms than the male patients. 4. Comparing the symptoms between the age groups(divided in two), the lower age group (20~59) had more dizziness and constipation symptoms than the higher age group (over 60). 5. Comparing the types of insomma between the age group, the higher age group (over 60) had more termination insomnia. 6. The types of insomnia of the entire insomnia patients were onset insomnia (73.1%), maintenance insomnia(20.6%), termination insomma(l7.1 %), shallow sleep (52.6%), listed by order of frequency. 7. The patients who takes hypnotics had more anorexia symptoms than the patients who doesn't take hypnotics. 8. There was no visible differences of the average fractal portrait between male and female. The age group of 20~30yrs. had the highest average fractal portrait, and the age group of 30~59yrs. the second highest, and the age group over 60yrs. the lowest. 9. The average of the regulation reserves of the autonomic nervous system(B2) - was lower than the regulation level of the ANS at the present (Bl). 10. When compared the priority of the function of the ANS, it showed that the proportion of HF($38.61{\pm}29.19%$)was the most, and than VLF($30.65{\pm}23.36%$), LF($20.04{\pm}19.13%$) the least. 11. The average of the compensation level of the central nervous system at present(Cl) - was lower than the compensation reserves of the CNS(C2). 12. The average of the control reserves of the cerebrum(D2) - was lower than the control level of the cerebrum at the present (Dl). 13. There was no visible differences between different sexes and ages in pulse rate. 14. The abdomen fat ratio above the line of the insomnia patients was 77.97% in male and 93.1% in female. Both sexes showed that insomnia patients had more abdomen fat that the standard, and female patients had more abd. fat than male patients. Conclusions : This study shows that the HRV of insomnia patients had no significant differences between gender. Fractal portrait, HF, LF and VLF of the insomnia patients are in inverse proportion to the age. The study of the Body Component Analysis showed that female had more abdomen fat than male, and both gender showed more abdomen fat than the standard. When looked into the accompanying symptoms of the insomnia patients, the symptoms show differences according to gender, age and hypnotics taking, as shown as below. In the entire patients, Headache was the most accompanying symptom. Female had more dry mouth, alternative periodic chill and fever, and hot flush symptoms than male. Higher age groups had more dizziness and constipation as accompanying symptoms than lower age groups. Patients who takes hypnotics had more anorexia than those who dont.

Liposuction is a useful method for debulking free flap. Recently, ultrasound assisted liposuction(UAL) has been reported to have many advantages over conventional suction-assisted lipectomy. We applied the UAL to debulk free fasciocutaneous flap of the forehead and lower extremities. The result was satisfactory and there was no significant complications worth noting. Although the cost can be expensive, it has many advantages such as less blood loss, larger amount of fat aspirate and better skin contraction. We can conclude that UAL can be a useful alternative method to debulk free fasciocutaneous flap.

We report the thoracoscopic resection of thymus and pericardial fat tissue in a patient who was in the setting of late severe myasthenia gravis[Osserman`s Group II-C-2 and previous tracheostomy state. The patient was 33-year-old female. She had been supported with mechanical ventilator for 88 days and suffered from recurrent pneumonia. Our first aim was to weaning her from mechanical ventilator. Traditional methods such as median sternotomy or transcervial thymectomy or transsternal sternotomy were difficult because of the anticipating complications of mediastinitis or morbidity, especially chest pain, following thoracotomy. We could wean her from the mechanical ventilator at postoperative 9 days. So, we concluded that video-assisted thoracoscopic thymectomy is a useful alternative tool in this case.

Cultured meat has been gaining popularity as a solution to the increasing problem of food insecurity. Although research on cultured meat started later compared to other alternative meats, the industry is growing rapidly every year, with developed products evaluated as being most similar to conventional meat. Studies on cultured meat production techniques, such as culturing new animal cells and developing medium sera and scaffolds, are being conducted intensively and diversely. However, active in-depth research on the quality characteristics of cultured meat, including studies on the sensory and storage properties that directly influence consumer preferences, is still lacking. Additionally, studies on the combination or ratio of fat cells to muscle cells and on the improvement of microbiota, protein degradation, and fatty acid degradation remain to be conducted. By actively investigating these research topics, we aim to verify the quality and safety of cultured meats, ultimately improving the consumer preference for cultured meat products.

본 연구는 미생물제제의 일종인 yeast culture 및 코팅 처리된 vitamin-C의 첨가 급여를 통해 비육 말기 Holstein 거세우의 증체 및 도체형질에 미치는 영향을 조사하기 위한 목적으로 실시하였다. 평균체중이 $714{\pm}13.60kg$인 18개월령 Holstein 거세우 24두를 공시동물로 이용하였으며 각각 8두씩 3개 시험구로(대조구, MC급여구, CVC급여구) 완전임의 배치하여 출하 전 3개월간 사양시험을 실시하였다. MC급여구는 yeast culture를 일일 30 g, 코팅 처리된 vitamin-C는 일일 10 g씩 매일 아침 사료급여 시 top dressing형태로 급여하였다. 일당증체량은 MC급여구가 가장 높았으며 사료요구율은 MC급여구와 CVC급여구에서 가장 낮았다. 등지방두께, 배체장근 및 육량은 시험구간 유의차가 없었다. 지육중량과 성숙도는 MC급여구에서 가장 높았으며, 지방색은 CVC급여구에서 가장 높게 나타났다. 이상의 결과를 종합해 보면 출하 3개월 전 Holstein 거세우에게 항생제 대체제로 미생물제제인 yeast culture 또는 코팅 처리된 vitamin-C의 급여는 육질에는 큰 효과가 없으나 육량, 지육중량, 사료요구율 등에 긍정적인 영향을 줄 수 있을 것으로 판단된다. 아울러 미생물제제와 vitamin-C를 함께 급여하면 더욱 좋은 효과가 있을 것으로 예상된다.

An oro-antral fistula(OAF) is one of the most common complications after procedures at the maxillary posterior area. The purpose of this study was to introduce the closure of OAF with repair of the Schneiderian membrane. This case report includes three patients with OAF arising after dental surgery on molar region of maxilla. Under general anesthesia, fistulectomy was achieved in all three patients and the full thickness flap around OAF was raised. After removal of inflammatory tissue, the Schneiderian membrane was repaired with suture or application of fibrin sealant. Additional closures were then performed with a buccal fat pad flap and a buccal mucoperiosteal flap. All OAF in three patients enrolled in this study were closed successively without recurrence of fistula. Treatment of oroantral fistula using repair of the Schneiderian membrane is a good alternative option for patients with OAF accompanied by chronic maxillary sinusitis.
