이 임상례는 근육 경직으로 인한 견비통에 태충혈이 유효함을 제시하고 있다. 환자의 주관적인 만족도를 평가하기 위해 점수식 평점 척도(Numerical rating scale;NRs)를 측정하였고 어깨 경직의 객관적인 호전 정도를 평가하기 위하여 양측 견정혈의 통증 통각 역치(Pressure pain threshold;PPT)와 어깨 외전력, 어깨관절의 외전시 가동범위(Range of motion;ROM)을 측정하였다. 양측 태충혈에 15분간 유침 후 NRS는 5에서 2로 감소하였다. 치료 전 왼쪽 견정혈의 PPT는 19N이었고 오른쪽은 22N이었다. 치료 후 왼쪽 견정혈의 PPT는 22N이었고 오른쪽은 27N이었다. 치료 전 견관절의 외전력은 왼쪽에서 29N, 오른쪽에서 22N으로 측정되었다. 치료후 견관절의 외전력은 왼쪽에서 33N, 오른쪽에서 22N으로 측정되었다. 견관절 ROM은 치료 전과 후 동일하게 왼쪽 관절 170도, 오른쪽 관절 165도로 나타났다. 결론적으로, 태충혈 자극은 어깨의 경직을 해소하고 어깨 근력을 강화하는 것으로 나타났다. 또한 그것은 상부 승모근의 압통을 감소시킬 수 있다. 이러한 측면에서, 태충혈의 효과에 대해서 보다 추가적인 연구가 필요할 것으로 보인다.

Conjunctival injection is the initial symptom of various eye diseases such as conjunctivitis, keratitis, or uveitis. The quantification of conjunctival injection may help the diagnosis and follow-up evaluation of various eye diseases. The size of the sclera is an important factor for the quantification of conjunctival injection. However, previous manual segmentation is time-consuming.Automatic segmentation is needed to extract the objective region of interest. This paper proposed a method based on the level set algorithm to segment the sclera from an anterior eye image. The initial model of the level set algorithm is calculated using the Lab color space, k-means algorithm and the geometric information. The level set algorithm was applied to the images in which the valley between the eyeball and skin was enhanced using the hessian analysis. This algorithm was tested with 52 images of the anterior eye segment. Results showed that the proposed method performs better than those with the level set algorithm using an arbitrary circle, or the region growing algorithm with color information. The proposed method for the segmentation of sclera may become an important component for the objective measurement of the conjunctival injection.

Purpose: To understand symptoms and signs in soft contact lens wearers the authors evaluate the attribution of the tear test to the contact lens related symptoms and signs. Methods: Sixty-two healthy soft contact lens wearers (23.95${\pm}$4.38 years old, 18.60${\pm}$16.92 months of prior lens wear) were participated in this study. 3 kinds of tear test and McMonnies' questionnaire test were performed for the soft contact lens wearers and subjective symptoms and objective signs were graded using CCLRU scales during the study period. Results: In this surveys, we found ocular dryness, redness and tiredness are the most common frequent and severe symptoms in soft contact lens wearers. Frequency of the ocular dryness, redness and tiredness are associated with grittiness, burning sensation and foreign body sensation respectively, and severity of the photophobia, foreign body sensation are associated with unstable vision and grittiness and which are associated with score of McMonnies' Questionnaire. Conjunctival redness and limbal redness are major signs but those are not need to be clinical care and rarely occurred corneal and conjunctival staining which are associated with tear break-up-time statistically. Conclusions: Dryness, redness and tiredness are primary common symptoms in Korean soft contact lens wearers. The frequency of those symptoms are increased with the period of soft contact lens wear and those are associated with other symptoms but have no relationship with signs.

목 적 : 전침 자극은 최근에 임상연구와 더불어 기초연구에서 자주 사용하는 방법으로 경락이론에 의거하여 신체에 분포되어 있는 경락상의 각종경혈부위에 인위적인 전기 자극을 통하여 질병을 치료, 예방 혹은 완화하는 방법이다. 이에 본 연구에서는 정상적인 쥐의 상태에서 일정한 전침 자극을 주었을 때, 심박변이도의 변화를 측정 하였다. 방 법 : 쥐의 정상적인 마취상태에서 태충혈에 4 Hz와 80 Hz의 5 V 크기로 10 mA 강도의 사각파 파형으로 자극을 주었으며 대조조로 비경혈 부위에 4 Hz의 동일한 파형으로 자극을 주어 심박 변이도의 변화정도를 측정하였다. 결 과 : 본 실험에서 RR Interval의 경우 태충혈 4 Hz 보다 80 Hz일때 RR Interval의 파형이 더 크게 나타났으며, PSD의 분석에서도 자극 전후를 비교하였을 때 $1{\sim}3$ Hz 사이에 높은 피크가 보였으며 4 Hz의 비경혈 부위에서는 큰 변화를 보이지 않았다. 결 론 : 이번 실험연구를 통하여 정상적인 쥐의 상태에서 일정한 전침 자극을 주었을 때, 심박 변이도 변화를 도출할 수 있었으며, 이번 실험을 통해 비수술적인 방법으로 치료효과와 심박 변이도를 측정할 수 있었고, 이를 통해 전침자극의 기전 연구에 있어 과학적 근거를 제시할 수 있다고 사료된다.

Purpose: To compare and analyze the ocular changes after wearing conventional and 2-weeks cosmetic tinted contact lens, which were made of different material and fabrication method. Methods: Thirty five university students, age of twenties, participated in this study. With daily wearing schedule, they had worn temporary cosmetic tinted lens for 2 weeks and conventional tinted lens for two month in their right and left eye, respectively. Subjective symptoms and objective signs were graded by using CCLRU scales and corneal thickness were measured after 1 day and 2 months wearing, and under or over 5 hours wearing in a day, respectively. Results: Major subjective symptoms found in the student wearing cosmetic tinted contact lens for a 1 day and 2 months were dryness, redness, foreign body sensation and itchiness. It was also found that those symptoms were more severe in left eye (conventional cosmetic tinted contact lens) than right eye (2-weeks cosmetic tinted contact lens). However, symptoms of redness in both eyes showed statistically significant difference in the case of 1 day and 2 months wearing and under or over 5 hours wearing in a day (p=0.000). After 2 months wearing, left eye with conventional cosmetic tinted contact lens showed limbal redness (p=0.000) and bulbar conjunctival redness (p=0.012) with statistically significance, whereas there was no significant difference in both eyes before lens wear. Left eye showed statistically significant changes in all objective signs, but right eye showed palpebral conjunctival redness, corneal staining and conjunctival staining. Therefore, it was concluded that conventional cosmetic tinted contact lens may be more effective on ocular changes after wearing of lens. A statistically significant changes in both eyes after wearing lens were found that corneal thickness increased about $5{\mu}m$ (p=0.001) in right eye whereas $7{\mu}m$ (p=0.004) in left eye. Conclusions: A statistically significant number of participants in this study preferred to wearing of high Dk/t temporary cosmetic tinted contact lens made by sandwich method which resulted in less ocular changes and may give more healthy and safe ocular conditions.

Silicone hydrogel contact lenses developed as a continuous-wear modality are now used as a daily-wear contact lenses. The purpose of this study was to investigate the clinical performance in a group of successful long-term wearers of conventional hydrogel contact lenses when refitted with daily wear $O_2OPTIX$ silicone hydrogel lenses. Sixty-two wearers ($30.7{\pm}19.9$ months of prior lens wear) among sixty-five soft lens wearers refitted with $O_2OPTIX$ silicone hydrogel lenses were participated in this study finally. Subjective symptoms were scored and objective signs were graded using CCLRU scales during the study period. 98% of subjects were successfully refitted with the one base curve of $O_2OPTIX$, and 33.9% of subjects were needed more or less lens powers compared with their habitual lenses. Subjects reported a concurrent reduction in dryness, redness and tiredness compared with their habitual lenses and both subjective and objective evaluations showed that dryness, tiredness, itchiness, bulbar and limbal hyperemia were decreased and significantly decreased particularly for those subjects with greater baseline symptoms (p<0.0001). But corneal staining was increased and was seen in many subjects during the study (p<0.0001). Refitting existing soft contact lens wearers with silicone hydrogel contact lens could result in a decreased in dryness, redness and tiredness, particularly more effective for those subjects with greater baseline of those symptoms. When patients using conventional hydrogel materials switch to a silicone hydrogel material, the potential for increased corneal staining should be considered and over-refraction should be needed to give a best vision.

Purpose : To identify clinical and laboratory features of atypical Kawasaki disease(KD), and to develop criteria for early diagnosis of atypical KD patients. Methods : All patients with KD treated at our hospital from January 1998 to June 2000 were reviewed retrospectively. Results : Among a total of 167 patients, 28(16.8%) were atypical KD of which seven(25%) were infants. Among the five cardinal symptoms, oral mucosal change(96.4%) occurred most frequently, followed by conjuntivitis(57.1%) and rash(46.4%). Most notable laboratory findings were anemia, and increased erythrocyte sedementation rate(ESR) or C-reactive protein(CRP). Coronary artery abnormalities developed in seven(25.8%) atypical KD patients, compared with 14.4% in typical KD patients. We considered oral mucosal change as major criterion, and conjunctivitis, rash, hematocrit <35% and ESR >30 mm/hr or CRP >3.1 mg/dL as minor criteria. Proposed modification in diagnostic criteria for atypical KD include fever of ${\geq}5$ days＋major criterion＋${\geq}2$ minor criteria, or fever of ${\geq}5$ days＋4 minor criteria. Conclusion : The modified diagnostic criteria has yielded a sensitivity 89.3%. Our diagnostic criteria may be used for early diagnosis of atypical KD.

Perchloryl fluoride의 직업적 노출기준 TLV-TWA 3 ppm(13 $mg/m^3$)과 TLV-STEL 6 ppm (25 $mg/m^3$)은 hydrogen fluoride와의 구조 유사성을 근거로 권고하였다. 이 수준은 호흡기계 기관지 자극 가능성을 최소화하는 수준이며 이는 실험동물 연구를 기초하였다. Perchloryl fluoride에 노출된 개, 몰모트, 흰쥐 그리고 생쥐에서 유발된 독성 증상 및 징후는 폐충혈, 부종, 호흡곤란, 청색증 그리고 비장, 간, 신장, 골수에서의 혈철소증이다. TLV-STEL은 폐에 대한 악영향과 플루오르 침착증에 대한 안전을 좀 더 확보하기 위하여 권고하였다. "피부흡수(skin)"와 "감작제(SEN)" 그리고 발암성에 대한 경고주석을 설정하기에는 유용한 자료가 부족하다.
