  • $\ulcorner$Uibujeolok$\lrcorner$ is a part of ${\ulcorner}$gogeumdoseojibseong[古今圖書集成]${\lrcorner}$ edited in 1726 Chinese Ching[淸] Dynasty. It refers ${\ulcorner}$Uibu[醫部]${\lrcorner}$ included in ${\ulcorner}$Bakmulhwipyeon Yesuljeon-Ha[博物彙編 藝術典下], and is composed of 520 volumes with 141 chapters. Though the name of Eubujeolok is used in most printed editions, the proper name was ${\ulcorner}$Uibujibseong[醫部集成]${\lrcorner}$ according to the original text of the copper type printing. Each category consists of 13 parts including Commentary, Diagnosis, and Organs and Bowels etc. And each chapter follows identical structure with categories. This composition type of ${\ulcorner}$Uibujibseong${\lrcorner}$ is similar with that of ${\ulcorner}$Dong-uibogam[東醫寶鑑]${\lrcorner}$ which was published 130 years ahead, but different from those of clinical books which published in China until then. Unusually there is no chapter dealing with Chinese herbs and acupuncture.

  • This review explores the factors that improve meat protein digestibility and applies the findings to the development of home meal replacements with improved protein digestion rates in older adults. Various methods improve the digestion rate of proteins, such as heat, ultrasound, high pressure, or pulse electric field. In addition, probiotics aid in protein digestion by improving the function of digestive organs and secreting enzymes. Plant-derived proteases, such as papain, bromelain, ficin, actinidin, or zingibain, can also improve the protein digestion rate; however, the digestion rate is dependent on the plant enzyme used and protein characteristics. Sous vide processing improves the rate and extent of protein digestibility, but the protein digestion rate decreases with increasing temperature and heating time. Ultrasound, high pressure, or pulsed electric field treatments degrade the protein structure and increase the proteolytic enzyme contact area to improve the protein digestion rate.

  • Higenamine, a benzyltetrahydroisopuinoline analog isolated from aconite tuber, has potent isotropic action. Recent studies suggest it may have beta receptor agonistic property in that its inotropic action is blocked by propranolol in isolated rabbit heart. However, no study has been carried out on other organs than heart. Higenamine is expected to have pharmacological actions on smooth muscle on the ground that it has catecholamine moiety and tetrahydrosioquinoline nucleus in its chemical structure, both of which are well known to have smooth muscle relaxation effects. Therefore present study was aimed at determining whether higenamine has bronchodilating effect in isolated guinea pig trachea smooth muscle rich in adrenergic beta receptor and if any, it has agonistic effect on beta receptor. The results were summarized as follows : 1. Higenamine had remarkable bronchodilating effect in guinea pig tracheal smooth muscle in a dose-dependent manner. 2. Bronchodilator effect of higenamine in isolated guinea pig tracheal smooth muscle was blocked competitively by propranolol. The $pD_2$ value of higenamine in isolated guinea pig tracheal smooth muscle was 5.65 and the $pA_2$ value of propranolol against higenamine in the same preparation was 7.97.

  • Ehlers-Danlos syndrome (EDS) is an inherited disorder of collagen biosynthesis and structure, characterized by skin hyperextensibility, joint hypermobility, aberrant scars, and tissue friability. Besides the skin, skeleton (joint) and vessels, other organs such as the eyes and the intestine can be affected in this syndrome. Accordingly, interdisciplinary cooperation is necessary for a successful treatment. Three basic surgical problems are arising due to an EDS: decreased the strength of the tissue causes making the wound dehiscence, increased bleeding tendency due to the blood vessel fragility, and delayed wound healing period. Surgery patients with an EDS require an experienced surgeon in treating EDS patients; the treatment process requires careful tissue handling and a long postoperative care. A surgeon should also recognize whether the patient shows a resistance to local anesthetics and a high risk of hematoma formation. This report describes a patient with a wide open wound on the foot dorsum and delayed wound healing after the primary approximation of the wound margins.

  • 간흡충(Clonorchis sinensis) 각기관의 미세구조와 그 기능에 관하여는 이제까지 많은 연구결과가 발표되어 왔으나 Laurer's canal에 대해서는 그 구조와 기능에 관하여 별로 보고된 바 없었으므로 저자는 이의 기능을 간접적으로 증명할 각종증거를 수집하기 위하여 광학현미경을 비롯하여 투사전자현미경 및 주사전자현미경을 이용하여 정자 및 난자의 주된 통로가 되는 수정낭, 정자관, 대수정관, 자궁 및 Laurer's canal 등을 면밀히 관찰하였다. 그 결과 자궁내에서도 부위에 따라 간욕적으로 정자가 관소되는 예는 있었으나 여러가지 정황으로 보아 자관이 정자의 주된 통로가 되지 않는다는 것은 명확한 사실이라 하겠다. 그렇다면 가능한 결론은 대량으로 생산 ·사정되는 정자들이 수정란에 도달하는 통로는 유일하게 Laurer's canal 뿐이라는 것이다. 이제까지의 관찰에 의하면 Laurer's canal은 잘 발달된 환상승섬유로 둘러싸여져 있으며 관내의 상피조직은 모종의 분필기능을 가지고 있는 것으로 사료되나 이에 관하여는 추후 자세한 연구가 요구되고 있다고 하겠다.

  • Because interventional procedure operates looking at premier as real time when perate intervention enemy, by patient is revealed during suitableness time in radiation, side effect such as radiation injury of skin is apt to happen. It established by purpose of study that measure exposure dose that patient receives about these problem, and find solution for radiation injury and repletion method. In this study, we used Rando phantom of identical structure with the human body which becomes accomplished with 4 branch ingredient of the attempt and system equivalent material them and absorbed dose were measured by TLD. According to the laboratory, it shows that operations such as TFCA procedure or uterine myoma embolization are more dangerous than TACE procedure. If both operations are inspected during a short time, it is not affected in being bombed. However, it can lead to palliative agenesis or depilate, definitive agenesis only if operations are repeated more than three times. Dose distibution based on experiment, to reduce radiation exposure to patients result from reduction of scatter ray as we control field size of radiation and protection of side organs except for tumor. also we knew that we can protect patients form radiation exposure, if we increas SOD and decrease SID.

  • 본 논문에서는 의료영상에서 특정 장기를 추출하여 질환 부위를 인식하는 알고리즘을 제안한다. 의료영상이 추출되어진 장기 부위에서 질환을 인식하기 위하여 단일 신경회로망을 이용하면 신경회로망의 학습 능력과 일반화 능력이 한정적이므로 성능개선에 많은 문제가 있다. 따라서 추출된 장기로부터 질환부위를 인식하는 것은 신경회로망을 복합적인 방법, 즉 RBF (Radial Basis Function), BP (Back Propagation)로 구성하여 단일 신경회로망의 단점을 극복하였다. 본 논문에서 제안하는 알고리즘은 입력 의료영상의 다양한 형태 변화에 적응력이 뛰어남을 실험결과로 알 수 있었다. 그리고, 전체 알고리즘의 수행시간이 장기추출 알고리즘을 포함하여 일반적으로 10초 이내에 수행됨을 실험 결과 알 수 있었다. 제안된 알고리즘은 실시간으로 의료영상의 질환부위를 인식하여 판별 자동화를 통해 원격의료에 사용 되어 질 수 있다.

  • Disabilities can emerge due to traumatic spinal fractures. In terms of sacrococcygeal spine, because of its unique anatomic structure with minimal movement, the possibility for it to have a disability is relatively low. In Korea, unlike most disability criteria, private insurance companies acknowledge angular deformities caused by vertebral fractures as disabilities according to their degree, so there were several cases where patients required compensation, arguing angular deformity caused by sacrococcygeal fracture, which in some cases led to legal conflicts. Except the Act Welfare of Persons with Disabilities which recognizes only severe angular deformity affecting internal organs as disability and the industrial accident disability evaluation which does not recognize coccygeal fracture as disability but rarely recognizes sacral vertebra deformity equivalent to compressive deformation, there is little or no case where angular deformity is recognized as disability. Given the impairment evaluation standards in social insurance, McBride system, American Medical Association (AMA) guides, and newly proposed standards by the Korean Academy of Medical Sciences (KAMS), the most contentious point in the general terms and conditions of private insurance is spinal deformity. To overcome controversy over disability evaluation, the private insurance sector is now applying criteria for axial skeleton to sacrococcygeal vertebrae through revision of standards. Under these circumstances, it is fair to recognize sacrococcygeal fracture as impairment in terms of the pelvis only when the fracture leaves serious deformity and neurological symptoms with clear relevancy. Though it may not be easy to develop accurate disability evaluation standards, improvement is necessary to remove any irrationalities and make the standards as objective as possible.
