이(lice)는 인체에 기생하면서 그들의 생활을 영위하고 여러 가지 질병을 전파하는 매개체로서 널리 알려져 온절족동물의 일종이다. 과거에는 인체에 발생하는 많은 질병의 매개체가 되었으나 그동안 의식주의 개선,공중 및 개인위생의 향상으로 최근에는 인체기생의 빈도가 많이 줄었으며 따라서 이에 의한 질병의 발생도 많이 감소하였다. 더욱이 안검을 침범한 음모이의 국내에 보고된 증례는 1976년 백 등이 보고한 2례, 1977년 신 등이 보고한 1례, 1996년 이 등이 보고한 1례, 1997년 김 등의 1례로 총 5례 뿐이다. 저자들은 세극등과 광학현미경 검사로 음모이에 의한 안검염으로 확진한후,세극등을 이용한 물리적 제거와 항생제 안약 및 연고의 도포를 하며 총 4주간 추적관찰을 하였으며 이 기간동안추가적인 음모이의 성충이나 충란의 발견이 없는 좋은 치료 결과를 경헝하였기에 이를 보고하는 바이다. We have experienced with a rare case of blepharitis caused by pubic lice, which was confirmed by slit-lamp and light microscopic examinations and resulted with a good outcome with appropriate treatment as follows. A two year old male child complained of foreign body sensations bilaterally, and an itching sensation at both upper and lower eyelids for 2 months. He was diagnosed with blepharitis caused by pubic lice after observation of adult louse and nits on slit-lamp examination. The treatment was accomplished by mechanical removal of the lices and nits by forceps and antibiotic eyedrops and ointment were applied to both eyes. The morphologic evaluation was performed with slit-lamp and light microscopy. The follow-up interval was a week for next one month and no louse or nit was found under slit-lamp examination. So we decided that the pubic lice was completely removed.

김광수,박원명,전태연,배치운,김대진,백인호,이철,김정수,한상익,최보문,장계호,고효진 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.3
연구목적 : Risperidone 투여후 조기 중단한 환자들과 장기적으로 계속 risperidone을 복용하고 있는 환자의 임상적 특성을 평가하고 나아가 risperidone장기 유지와 조기 중단의 요인을 분석하고 정신병리가 약물 투여에 미치는 영향을 조사하고자 하였다. 방 법 : 연구 대상자는 1996년 1월부터 1996년 12월까지 가톨릭대학교 의과대학 부속 8개 병원 정신과에서 risperidone을 투여 시작한 환자 580명중 DSM-IV기준에 의해 정신분열병으로 진단받고 투여 기간이 6개월 미만(조기 중단군)이거나 2년 이상(장기 유지군)을 경과하였으며 의무기록의 누락이 없는 210명을 선정하였다. 두 군간 임상적 특성을 조사하기 위하여 인구학적 변인, 정신병리학적 변인, 약물 투여기록 및 부작용 등을 과거 의무기록을 근거로 평가하였다. 결 과 : 대상환자 210명 중 조기 중단군이 67명(31.9%)이었고 장기 유지군은 143명(68.1%)이었으며 두 군간 인구학적 변인과 정신병리학적 변인에 따른 특징에는 두 군간 차이가 없었다. 두 군간 risperidone의 시작 용량과 변인과 정신병리학적 변인에 따른 특징에는 두 군간 차이가 없었다. 두 군간 risperidone의 시작 용량과 최대 용량은 유의한 차이가 없었으나 유지용량은 조기 중단군에서 4.49(±1.44)mg,장기 유지군에서 3.67(±1.50)mg으로 유의한 차이가 있었다(t=3.698, p<0.05). 또한, 이전 항정신병약물의 사용 기왕력 변인에서 조기 중단군은 기왕력이 없는 환자가 39명(58.2%), 고역가 항정신병약물을 사용한 기왕력이 있는 환자는 27명(40.3%), 저역가 항정신병약물을 사용한 기왕력이 있는 환자는 1명(1.5%)이었고, 장기 유지군은 기왕력이 없는 환자가 58명(40.6%), 고역가 항정신병약물을 사용한 기왕력이 있는 환자는 77명(53.8%), 저역가 항정신병약물을 사용한 기왕력이 있는 환자는 8명(5.6%)으로 유의한 차이가 있었다.(x²=6.559, df-=2, p<0.05). 결 론 : 본 연구결과에 의하면 가급적 환자 상태에 따라 낮은 최적 치료 용량을 투여하는 것이 장기잔의 투여를 바람직한 것으로 생각된다. 본 연구와 같은 대규모의 후향적 자연적 연구는 일반 실제 진료에서 risperidone의 효과 및 기타 다른 측면에서의 유용한 정보를 얻을 것으로 기대된다. Objective : This retrospective naturalistic study was designed to compare the clinical characteristics including psychopathology of two groups of patients, long-term maintenance group and short-term drop-out group, who were taking risperidone. Method : Datas were collected for 210 schizophrenic patients with complete medical records among 580 patients who were enrolled with risperidone administration from January 1996 to December 1996 in 8 affiliated hospital of the Catholic University. The short-term drop-out patients group were assigned to whom treatment period was less than 6 month, and the long-term maintained patients group, treatment period was more than 2 years. We assessed demographics, psychopathology, and other variables related with medication based on past medical records. Results : Among subjects of 210, short-term drop-out patients group were 67(31.9%) and long-term maintained patients group were 143(68.1%). Demographics and psychopathology were not significantly different between two groups. The stating and maximal dosage of risperidone was not significantly different between two groups but the maintenance dosage of risperidone was lower in long-term medicated patients group than short-term drop-out patients group(t=3.698, p<0.05). Additionally, the result of this study showed differences in experiences of past antipsychotic use as following. The number of no previous use of antipsychotic was 39(58.2%), the number of high potency amtipsychotic use was 27(40.3%), and the number of no previous use of antipsychotic was 58(40.6%), the number of high potency ntipsychotic use was 77(53.8%), the number of low potency antipsychotic use was8(5.6%) in long-term maintained group.(x²=6.559, df-=2, p<0.05). Conclusions : According to these results, administration of low therapeutic dosage should be recommended for long-term maintenance as if possible. Multi-center based retrospective naturalistic study like this would be useful for getting informations about efficacy and some other aspects of antipsychotic administration in practial field.

Si Bulk Micromachining을 위한 Wafer Rolling Etching 및 그 특성
김건년,이보나,박효덕,신상모,공경준,장동근,김병철,권혁채,이봉희 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1
A wafer rolling etching system for the silicon bulk micromachining has been designed and fabricated. The silicon diaphragms were anisotropically etched in a 24.5 weight percent KOH solution. Compared to the conventional KOH etching systems, pyramidal hillocks, and wave-shaped structures on the etched surfaces were greatly reduced by using this system. After etching for time of 438 minutes, the average etched depth and the etch-rate were measured to be 537μm and 1.22μm/min, respectively. The average etching uniformity of etching depth was 0.87% in 5-inch wafer. Our results showed that the wafer rolling method enhanced etch uniformity and etch rate.

Background/Aims: We sought to increase our understanding of the rhinitis-asthma relationship and improve strategies for the treatment of patients with these diseases. The aim of this study was to identify a connection between upper airway inflammation and lower airway responsiveness. Methods: We counted eosinophils on nasal smears, and performed spirometry, allergic skin tests, and methacholine challenge tests in 308 schoolchildren plus a questionnaire on respiratory symptoms. The methacholine concentration causing a 20% fall in forced expiratory volume in 1 second (PC20 < 25 mg/mL) was used as the threshold of bronchial hyperresponsiveness (BHR). Results: In total, 26% of subjects had positive nasal eosinophils on a smear, and 46.2% of subjects had BHR at < 25 mg/mL methacholine PC20. Nasal symptoms were higher in subjects with than without nasal eosinophils (p = 0.012). Asthma symptoms did not differ between subjects with and without nasal eosinophils. Nasal eosinophils were higher in subjects with atopy than those without (p = 0.006), and there was no difference in PC20 methacholine according to atopy (15.5 ± 1.07 vs. 17.5 ± 0.62; p > 0.05). No difference in BHR was detected when comparing subjects with and without nasal eosinophils. There were significant differences in the PC20 between subjects with greater than 50% nasal eosinophils and without nasal eosinophils (11.01 ± 2.92 mg/mL vs. 17.38 ± 0.61 mg/mL; p < 0.001). Conclusions: These findings demonstrated that nasal eosinophilic inflammation might contribute to lower airway responsiveness in schoolchildren, based on an epidemiological survey.

Purpose: Though prompt diagnosis to minimize symptom duration (SD) is highly associated with organ salvage in cases of testicular torsion (TT), SD is subjective and hard to determine. We thus investigated the clinical implications of systemic in-flammatory responses (SIRs) as potential surrogates of SD to improve testis survival. Materials and Methods: Sixty men with TT that underwent immediate operation among orchiectomy and orchiopexy follow-ing a visit to a single emergency department were retrospectively enrolled. Mandatory laboratory tests conducted included neutrophil, lymphocyte, and platelet counts. Results: Mean age and SD was 15.7±3.7 years and 8.27±4.98 hours, respectively. Thirty-eight (63.3%) underwent orchiec-tomy and the remaining 22 underwent orchiopexy. Leukocytosis (p=0.001) and neutrophil-lymphocyte ratio (NLR, p<0.001) were significantly lower in the orchiopexy group as was SD (3.27±1.88 vs. 11.16±3.80, p<0.001). Although multivariate model showed that the only single variable associated with receipt of orchiopexy was SD (odds ratio [OR]=0.259, p<0.001), it also revealed NLR as a sole SIR associated with SD (B=0.894, p<0.001). While 93.3% with a SD of within 3 hours under-went orchiopexy, only 26.6% of affected testes were preserved between 3 to 12 hours (n=30). When multivariable analysis was applied to those with window period, NLR alone predicted orchiopexy rather than orchiectomy (p=0.034, OR=0.635, p=0.013). The area under curve between SD (0.882) and NLR (0.756) was similar (p=0.14). Conclusions: This study showed NLR independently predicted testis survival by proper surgical correction particularly for patients with marginally delayed diagnosis, which suggest the clinical usefulness for identifying candidates for orchiopexy in emergency setting.
