본 논문에서 소개하는 기기는 병의원의 수술실에서 수술전용조명인 무영등만으로는 직접 조명할 수 없는 수술부위의 환부에 근접 국부조명을 제공하는 장치로서, 임상의들이 인체 깊숙한 환부의 질환 치료를 안전하게 시술하도록 한다. 이 의료 보조조명 장치는 종양제거나 혈관봉합과 같은 미세한 수술과정에서 발생할 수 있는 치명적인 수술 실패를 방지하기 위해서 필요한 장치이다. 광원 및 전원부 등의 구성요소는 저전력, 소형화로 설계되었으며, 협각렌즈를 사용하여 광확산 효과의 증가와 집중 조명에 용이하도록 하였다. 광케이블을 사용한 조명전송과 조명장치의 Endcap은 사용 후 다음 환자를 위하여 소독이 가능하도록 방수형으로 설계되었다. 리트렉터 조명장치 개발 후 이루어진 광원특성 측정 결과, 조도 490lux, 휘도 $11,550cd/m^2$, 연색성 78, 색온도 11,000K 및 고른 조도분포도를 보여 국부 의료보조조명으로서 적합하였음이 확인되었다.

본 연구의 목적은 광 유도에 의한 nitric oxide (PIANO)유리가 혈관이완에 대해 cyclic GMP (cGMP)가 관여하는 지의 여부와 아울러 ${\alpha}$-수용체를 통한 수축에 PIANO가 어떻게 작용하는 지를 파악하고자 하였다. In vitro 실험에서 흰쥐의 대동맥을 준 최고농도의 phenylephrine (PE)으로 수축시킨 후 nitric oxide 생성을 변화시키는 약물이나 광민감성 (photosensitizing) 약물에 대한 반응을 등장력 변화로 기록하였다. PIANO에 의한 혈관이완은 광노출 강도와 기간 및 광민감성 약물농도에 비례하여 증가하였고 cGMP의 증가를 수반하였다. PE에 의해 증대되는 phosphatidylinositide(PI) 전환은 PIANO에 의해 억제되었다. 이상의 결과는 cGMP의 증가로 인해 PIANO에 의한 혈관이완이 일어나며 ${\alpha}$-아드레날성 수용체 자극에 의한 PI 전환의 억제현상은 cGMP 증가의 결과로 생각할 수 있다. 결론적으로 PIANO에 의한 혈관이완은 cGMP의 증가로 인함을 확인할 수 있었다.

이 연구의 목적은 6 MV 광자 빔에 대하여 팬텀 표면으로부터 1 cm 깊이에서 조사야 가장자리 바깥 축외선량비와 1 mmPb의 차폐비를 조사하는 데 있다. 180 cGy의 선량은 SAD기법에서 $10{\times}10cm^2$와 $15{\times}15cm^2$ 조사야에 대하여 깊이 10 cm에 전달되었다. 축외선량비는 조사야의 중심축과 가장자리로부터 2, 4, 6 cm에 위치된 광자극형광나노닷선량계(OSLnD)들의 선량을 측정하여 계산하였다. 그리고 1 mmPb의 차폐비는 조사야 가장자리로부터 2, 4, 6 cm에 위치된 OSLnD들의 선량을 측정하여 산출하였다. 결과로서, $10{\times}10cm^2$와 $15{\times}15cm^2$ 조사야에 대하여, 축외선량비들은 0.008-0.023과 0.011-0.028을 각각 얻었다. 또한 1 mmPb의 차폐비들은 0.868-0.888과 0.807-0.842을 각각 얻었다. 이 결과들은 방사선치료 조사야 바깥에 위치한 위험장기들을 보호하기 위한 자료를 제공한다.

Temporomandibular joint disorder(TMJD) was mainly characterized with joint pain, motion limitation, joint sound, resulted from pathologic conditions in temporomandibular joint and around tissue. As temporomandibular joint is one of decisive factors determining the occlusion, disorders in temporomandibular joint may cause the occlusal changes. The causes of occlusal changes related with TMJD can be classified into 2 categories; (1) those related to progression of disorder, 2) those related to treatment of the disorder. The clinical manifestation of occlusal changes depend on their causes and affected site. Therefore, whenever possible, treatment should be directed to the relief of the underlying causes, However, it is not always possible to relieve the underlying conditions. Moreover, some occlusal changes may remain irreversible even after the considerable improvement in clinical symptoms. Regarding the treatment of the permanent occlusal changes, it has been reported that the extensive occlusal treatment including occlusal adjustment, prosthodontic treatment, orthodontic treatment should be applied. Here, we present with a case report of occlusal change caused by the progressive temporomandibular joint disorder, together with introducing the intermaxillary traction appliance as the possible treatment option.

Oral prostaglandin E1 (PGE1) is a medicine that is clinically applied during a treatment of patients suffering with vascular disease with chronic arterial obstruction because it has vasodilation and anti-platelet effects. The mechanisms of lumbosacral symptoms associated with spinal stenosis probably include vascular insufficiency with hypoxic injury to the cauda equina and the nerve roots. Thus, increasing the blood supply would be beneficial to improve the pathophysiologic condition. Several studies on the improvement of clinical symptoms of spinal stenosis by PGE1 treatment have been reported on. In this case, 47-year old female underwent posterior compression and posterolateral fusion with a cage at L2-4 due to L3 compression fracture, and she did not show improvement of the radiating pain of her right leg after the operation. Therefore, she received repetitive epidural catheterization and adhesiolysis, epidural block and physical therapy, but her symptoms deteriorated after temporary improvement. Finally, she was given PGE1 and the radiculopathy was completely improved, although some muscle weakness still remained.

Purpose: The purpose of this study was to evaluate outcome of ankle arthroscopy with high anteromedial and anterolateral portals for osteochondral talar lesion. Materials and Methods: A prospective study was conducted between March 1992 and January 2000 by one surgeon. Total 48 patients who had osteochondral talar lesion were included. Using high anteromedial and anterolateral portals, arthroscopic treatment was performed. A functional evaluation was performed with the Karlsson scoring scale. Results: Of the 48 patients, 28 cases had anterolateral talar lesion and 18 cases had medial talar lesion and 2 cases had central lesion. The 42 cases(87.5 %) had trauma history. On Karlsson scoring scale, anterolateral talar lesion was better than medial talar lesion(p=0.035). Conclusion: Using high portals, we could get better visualization of talar dome and posterior chamber of ankle, and do some limited procedures without additional portals. Osteochondral lesions were treated successfully only when they were traumatically induced and localized without diffuse chondromalacia of talus and tibia.

The size of ovarian follicle in preovulation, luteal stage and follicular cyst was 18.9, 9.2 and 27.6 mm, respectively, and the thickness of follicular wall was 2.3, 1.8 and 2.8 mm, respectively. The size of corpus luteums in formation stage, activity stage, regression stage, cystic corpora lutea and luteal cyst was 6.2, 11.3, 8.6, 26.7 and 25.9 mm, respectively. The thickness of luteal wall in cystic corpora lutea and luteal cyst was 8.4 and 4.9 mm, respectively. The size of embryo or fetus on day 25, 27, 30, 35, 40, 45 and 50 was 0.8, 0.9, 1.3, 1.5, 2.2, 2.8 and 3.8 cm, respectively.

We developed the 4channel Light Medical Therapy Apparatus for External Injury Cure using a high brightness LED. This equipment was fabricated using a micro-controller and a high brightness LED, and designed to enable us to control light irradiation time, intensity, frequency and so on, Especially, to control the light irradiation frequency, FPGA was used, and to control the change of output value, TLC5941 was used. Control stage is divided into 4 levels by program. Consequently, the current value could be controlled by the change of level in Continue Wave(CW) and the output of a high brightness LED could be controlled stage by stage. Compared with one LED irradiation, several LEDs irradiation could increase optical power.
