  • Objective : The Sinseon-yukza-hwan (SSY), a Korean medicinal formula which includes Radix Rehmanniae Preparata and other medicinal herbs, has long been used for treatment of alopecia and gray hair through oral administration. This study is designed to enhance the utilization of natural materials in hair and scalp-related cosmetics. Possibility of SSY as an antioxidant was examined from its 50% ethanol extract. Methods : The antioxidative capacities were evaluated by determining total phenolic and flavonoid contents, 1,1-diphenyl-2-picryl hydrazyl (DPPH), 2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), reducing power and hydroxyl radical scavenging activity. Results : Total polyphenol and flavonoid contents of SSY were 25.53 mg TE, tannic acid equivalent/g and 18.90 mg RE, rutin equivalent/g, respectively, which correlated strongly its antioxidative activity. The DPPH and ABTS free radical scavenging activities of SSY at $0.1mg/m{\ell}{\sim}5mg/ml$ were ranged from 20% to 85% and 10% to 58%, respectively. Also the hydroxyl radical scavenger activity and reducing power increased in SSY-treated group, which were significantly lower in SSY-compared to BHA-treated group. But the highest reducing power was shown as 79% from SSY-treated group, which was higher value than 65% from BHA-treatment. These results showed that SSY extract effectively inhibited the generation of free radicals in the all assay system with dose-dependent manners. Conclusions : Thus, the present study provide preclinical data to support the expanded application of SSY, which could be potential candidates for natural antioxidants.

  • 본 연구는 졸업시점의 치의학전문대학원생 79명을 대상으로 소아치과학 OSCE(Objective Structured Clinical Examination)성적과 이전까지 이수한 소아치과학 교과목들 성적간의 관계를 분석함으로써 소아치과학 교육과정 운영을 평가하고 발전적 시사를 도출하는 데에 목적이 있다. 소아치과학이론 교과목은 이전 이수과목인 임상전단계실습 성적(r = 0.449, p = 0.000), 이후 이수과목인 임상실습성적(r = 0.437, p = 0.000)과 상관관계가 있었다. 하지만 졸업시점의 OSCE성적은 단지 임상전단계실습 과목 성적(r = 0.302, p = 0.003)과 상관관계를 보였다. 이는 OSCE 신뢰도가 Cronbach's ${\alpha}0.733$을 고려하면 OSCE 자체 문제보다는 교육과정 상에 있어서 임상실습 교과목 운영에 문제가 있음을 추론할 수 있다. 치과대학병원에서 교수의 특진을 선호하고 학생들에 의한 진료를 기피하는 진료 현장에서 학생들에 대한 직접적인 지도와 피드백을 통해 임상역량을 강화하기 위해서는 학생 지도를 위한 교수 수 확보와 같은 교육여건이 마련되어야 한다. 또한 이론적 지식 및 술기교육이 임상진료 현장에서 잘 적용되고 심화되기 위해서는 교육과정에 대한 보다 구체적인 평가와 함께 임상실습 단계에 있어서도 기본적 술기에 대한 지속적인 교육과 평가가 점검되도록 하는 실질적 개선 방안이 모색되어야 한다.

  • 최근 미세혈관 문합수술 시 봉합사 대신 기계식 문합커플러를 사용하는 수술례가 증가하고 있다. 그러나 기존의 비분해성 문합커플러는 염증반응 뿐만 아니라 수술 후 영구적으로 인체 내에 잔존한다는 한계성이 있다. 따라서 본 연구에서는 기존 비분해성 문합커플러의 한계성을 극복하기 위해 사출성형공정을 이용한 생분해성 PCL 문합커플러 제작을 채택하였다. 사출성형 공정조건 중 실린더온도와 사출압력에 따른 수축률을 계산하고 이에 따른 문합강도를 측정하였다. 그 결과 핀보다는 홀 파트의 수축률 변화가 크게 나타났다. 또한 수축률은 실린더온도가 상승할수록 증가하였으나 반대로 사출압력이 높아질수록 감소하는 경향이 나타났다. PCL 문합 커플러의 in-vitro 분해거동을 12주간 평가한 결과, 수분흡수는 증가하고 분자량은 감소하여 생체분해를 동반한 질량 및 문합강도의 감소를 확인할 수 있었다. 그러나 문합강도의 저하 수준이 전임상 요구조건을 충분히 상회하기에 PCL 문합커플러는 미세혈관수술에 적합한 후보재료임을 파악할 수 있었다.

  • Background Plastic surgery has developed to benefit in a variety of challenging areas formerly handled by other disciplines. Medical students do not have a clear picture of plastic surgery as a career due to lacking scope, clinical practice, and understanding of plastic surgery as a clinical area of expertise, including general practitioners, nursing staff, medical trainees, and the general public, and misconceptions about the extent of reconstructive and plastic surgery. Methods A cross-sectional observational study was conducted on Kuwait University Medical students (2nd-7th Years) over a period of 1 month. A questionnaire and a consent form were provided to eligible students. The inclusion criteria were Kuwait University Medical students from 2nd to 7th Years with signed consent form. The response was collected via email sent in coordination with the Vice Dean of Student Affairs in the Faculty of Medicine. Using statistical package for the social sciences, responses were statistically analyzed. Pearson's chi-square test was used to calculate p-values, where p < 0.05 was considered statistically significant. Results A total of 244 eligible medical students, 121 males and 123 females, were included in the study, with a mean age of 21 (±2) years. Similarly, 126 (51.6%) were preclinical students (2nd-4th-year students), while 118 (48.4%) were clinical students (5th-7th-year students). About 79.8% of medical students believed that plastic surgery plays an essential role in trauma management, whereas 9.2% did not consider plastic surgery significant for trauma management. This study found that only 15.5% of medical students were interested in enrolling in plastic surgery residency after graduation, while 47.1% of students did not consider plastic surgery residency after graduation. However, 37.4% were uncertain. The two most driving factors in deciding on plastic surgery residency were expected income (61.8%) and lifestyle (14.3%). Conclusion Improving medical students' education quality can enhance their perception and awareness of plastic surgery. Students should be taught the broader scope of plastic surgery. The inclusion of formal training during undergraduation is the essence of time and should be added to or improved during plastic surgery rotations with more emphasis on reconstructive and hand/peripheral nerve surgery. Student-led interest groups can be a useful tool for educating students about their specialty.

  • Arriving in the '90s, the worldwide trend of longing for naturalism and popularity of complementary and alternative medicine in America has caused traditional Oriental Medicine and medicinal plants markets to develop rapidly. And China has been pursuing the globalization policy of Chinese medicine by the initiation of the society of traditional Chinese medicine. Under this situation, it is a time for us to think about in a serious manner whether existing organization and system of Oriental medicine and the department of Oriental medicine at the schools in Korea reflects reality or whether we should turn it to some different direction. The purpose of this research is to compare the educational systems in relation to the traditional medicine between Korea and China, and to seek and look into its implication, and also to make a contribution to further developments and changes of direction for Oriental medicine education in Korea. 1. I investigated carefully the educational system of the colleges of traditional Chinese medicine, and results from this survey revealed that the academic institutions for the medicinal training in China consists of varied systems, such as 7-year program for medicinal training linking with master degree course, 6-year program, 5-year program (more than 90%), 4-year program, and so on, so then China has been raising the specialists in their traditional medicine arena through those varied academic programs. Such an educational system as the department of Chinese medicine in order to educate and produce specialists or pharmacists specializing in traditional Chinese medicine is operated only by Beijing University of Chinese Medicine in terms of 7-year academic program for medicinal major that linked with master degree course, and the rest of schools run 5-year program or 4-year program (more than 90%). And other human resources required for cultivation of medicinal plants and manufacturing herbal medicines are mostly trained at 3-year course colleges or 2-year course vocational schools. 2. In connection with traditional Chinese medicine, there are a variety of departments in the schools in China other than Chinese Medicine and Pharmacology: i.e. Acupuncture, Moxibustion and Tuina, Preclinical Medicine, Pharmaceuticals, Materials of Medicine, Phrenology and Law, Languages and Literature, etc. Therefore, these programs constitute multi academic system and also an appropriate educational base that fits in varied needs of market. Particularly, the university having 7-year program emphasize, English proficiency so that it can be considered that this academic program is a specialized course in order to achieve globalization of Chinese medicine. 3. In Korea, there are only 11 Oriental medicine schools with 6-year program which have been established by the private foundations and 3 departments of Oriental medicine at 4-year university. Therefore, we need to establish varied departments related to branches of our traditional medicine like China. 4. It is necessary to establish varied new departments related to Oriental Medicine that will be able to take a professional role in the course of pursuing the strategic goals such as scientification, globalization, standardization of Oriental Medicine, also that will meet needs of the world alternative and complementary medicine and herbal medicine markets. In order to achieve such strategic goals, we need to organize an academic system that will be different from existing systems and programs, also we are required to research further on the educational and training programs.
