연구배경: 폐확산능을 해석하는 데 필요한 정상예측식으로는 한국인을 대상으로 하여 박 등이 개발한 식(박 식)이 있으나 아직 외국 정상예측식을 많이 사용하고 있다. 이에 국내에서 많이 사용하는 외국 정상예측식인 Burrows 식과 박 식의 임상적 유용성과 정확성을 비교하고자 하였다. 방법: 1. 임상적 유용성 연구; 2006년 7월부터 12월까지 6개월간 폐확산능검사를 시행한 환자 중 두 식을 각각 정상예측식으로 적용하였을 때 폐확산능 해석이 다른 276명(대상군 A)을 대상으로 하였다. 대상군 A에게 두 식을 각각 적용하였을 때 폐확산능 해석과 임상적 판단과의 일치도를 비교하여 임상적 유용성을 평가하였다. 2. 간질성폐질환 진단의 정확성 비교; 2001년부터 2006년까지 폐조직검사를 시행하여 확진된 간질성폐질환군과 서울아산병원에서 모집한 정상군을 대상으로 하여 정상예측식으로 두 식을 각각 적용하였을 때 폐확산능 해석의 정확도를 비교하였고, 두 식이 차이가 나는지 맥니머의 카이스퀘어 검정을 하였다. 결과: 1. 임상적 판단과의 일치도 비교; 276명을 임상정보를 토대로 폐확산능을 예측하여 분류한 결과 정상 54명, 감소 220명, 불분명이 2명이었다. 예측식으로 박 식과 Burrows 식을 적용하였을 때 임상적 판단과 일치하는 환자는 각각 78%와 22%이었다(p<0.001). 2. 간질성폐질환 진단의 정확성 비교; 박 식은 민감도 90.1%, 특이도 100%이었고 Burrows 식은 민감도 64.2%, 특이도 100%로 민감도가 통계학적으로 유의하게 박 식이 높았다(p<0.001). 결론: 우리나라 정상예측식인 박 식이 외국 정상예측식인 Burrows 식을 정상예측식으로 적용하는 것보다 임상적 유용성이나 간질성폐질환 진단의 민감도에서 더 우월하였다. 향후 폐확산능검사의 정상예측식으로 박 식을 사용해야 할 것으로 사료된다. Background: Park et al. developed the Korean reference equation for the measurement of diffusing capacity in 1985. However, the equation has not been widely used in Korea and foreign reference equations have been popularly used. We intended to compare the clinical usefulness and the accuracy of the the Korean reference equation (Park`s equation) with that of the foreign equation (Burrows` equation) that is commonly used in Korea. Methods: 1. Evaluation of clinical usefulness; Among 1,584 patients who underwent diffusing capacity (DLCO) at the Asan Medical Center from July to December 2006, group A subjects included 276 patients who had different interpretations of DLCO in trials employing Burrows` equation and Park`s equation. Clinical assessment was decided by consensus of two respiratory physicians. In order to evaluate the clinical usefulness of Burrows` equation and Park`s equation, agreement of clinical assessment and DLCO interpretation were measured. 2. Evaluation of accuracy; Group B subjects were 81 patients with interstitial lung disease (ILD) and 39 normal subjects. The 81 ILD patients were diagnosed following a surgical lung biopsy. The accuracy of diagnosing ILD as well as sensitivity and specificity were evaluated according to the use of the reference equations (Burrows` equation and Park`s equation) for DLCO. Results: Agreement between clinical assessment and interpretation of DLCO was 22% for the use of Burrows` equation and 78% for the use of Park`s equation. The sensitivity and specificity of the Burrows` equation for diagnosing ILD were 64.2% and 100%. The sensitivity and specificity of the Park`s equation for diagnosing ILD were 90.1% and 100%. The sensitivity of the Park`s equation for diagnosing ILD was significantly higher than that of Burrows` equation (p<0.001). Conclusion: The Korean reference equation (Park`s equation) was more clinically useful and had higher sensitivity for diagnosing ILD than the foreign reference equation (Burrows` equation).

This study was conducted to find a correlation between blood COHb and calculated COHb with expiratory air and related variables such as occupational and smoking factors. Author selected 69 healthy workers in 8 workplaces suspected CO exposure. Basic informations were collected by self-reported questionnaire and medical history taking. Author measured Indirect COHb concentration with expiratory air using Micro II-Smokerlyzer and blood COHb concentration using Oxymeter. The results of the study were summarized as follows : 1. In the smoker, mean blood COHb and calculated COHb with expiratory air were 2.21±0.98% and 2.27±0.97 %, and there was not a statistically significant difference. In the non-smoker, mean blood COHb and calculated COHb with expiratory air were 0.42±0.43 % and 0,65±0.30 %, and there was also not a statistically significant difference. 2. There were positive correlations between blood COHb and calculated COHb with expiratory air in both the smoker (r=0.91, p=0.0001) and non-smoker (r=0.73, p=0.0001). 3. In the smoker, the factors affected COHb were total smoking index (Pack × years) and passed time after the last smoking. 4. In the nonsmoker, the parking and driving groups had higher COHb concentration than others (p<0.05). In conclusion, there was no significant difference between indirect COHb concentration with expiratory air using Smokerlyzer and blood COHb concentration and there was a highly significant correlation between indirect and blood COHb concentrations. Therefore indirect COHb concentration with expiratory air is a useful screening method for CO exposure. Author suggest the resection of smoking during at least 90 minutes before measuring COHb concentration in order to exclude smoking effects.

This study was conducted to find out toxicity of compost made of food waste to cucumber seed germination and seedlings growth when it was mixed with Mixlite for bed substrate. Mixlite was solely used as bed soil, or mixed with food waste compost ranging 1% to 100% (w/w). Germination percentage and seedling growth of cucumber were examined in 4 weeks after seedling. When cucumber seeds were sowed in Mixlite mixed with food waste compost at 100, 50, 30, 20, 10 or 1%, germination percentages were 30, 36, 38, 46, 74 and 84% compared to with control(100%), respectively. It showed that germination percentage percentage was adversely affected by the amount of food waste composed mixed in the bed substract. Plant height and hypocotyls diameter, root length and root fresh weight, hypocotyls fresh weight and cotyledon fresh weight of cucumber seedling were similarly adversely affected by the amount of food waste compost. Optimum content of the food waste compost for cucumber nursery substrate was found to be 1% of Mixlite.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

연구목적: 정신분열병은 유전적 성향이 강한 정신 질환의 하나로, 최근에는 분자유전학적 기법을 이용하여 유전자 다형성과 질환사이의 연관성을 밝히는 연구가 정신분열병의 유전학 연구에서 중요한 부분을 차지하고 있다. 이에 본 연구는 중추신경계와 면역계간 상호작용에 관여하는 싸이토카인 중 종양괴사인자베타 (TNFβ) 유전자의 다형성을 분석하여 정신분열병에서의 유전적 관련성을 알아보고자 하였다. 방법: 환자군은 DSM-IV에 의하여 정신분열병으로 진단된 환자 146명을 선정하였고, 정상 대조군으로는 가톨릭 조혈모세포 정보은행에서 보유하고 있는 정상한국인 202명의 자료를 이용하였다. 전혈(whole blood)에서 DNA를 추출하고 TNFβ 유전자 부위를 증폭한 후 제한효소 NcoI과 반응시켰다. NcoI으로 전달되어 555bp와 185bp의 절편을 갖는 TNFB1과 NcoI 절단부가 없어 740bp의 절편을 갖는 TNFB2 등 2가지 대립유전자의 제한효소절편길이 다형성을 조사하였다. 모든 자료의 분석은 χ² 검증을 이용하였다. 결과: 정신분열병 환자군과 정상 대조군 간에 TNFB의 유전자형 TNFB1/1, TNFB1/2의 발 현 빈도에는 유의한 차이는 없었다. 정신분열병 환자군과 정상 대조군간 TNFB1과 TNFB2의 대립 유전자형의 분포는 유의한 차이가 있었다. 결론: 본 연구 결과 정신분열병의 후보 유전자로 종양괴사인자베타의 대립 유전자가 가능성이 있음을 확인하였고, 향후 연구에서는 보다 통합적이고 체계적인 연구가 이루어져야 할 것으로 생각되었다. Objective: Schizophrenia is known to have high genetic influences. Recently, the main focus of etiologic study in schizophrenia has been concentrated on molecular genetic approach including polymorphism analysis. This study was designed to investigate the relationship between schizophrenia and immunologic influences by analyzing polymorphism of TNFB that is involved in interaction between immunologic system and CNS. Method: 146 schizophrenic patients diagnosed by DSM-IV criteria were included and data of 206 normal population from the Catholic Hemopoietic Stem Cell Information Bank(Seoul,Korea) were used as a control group in this study. DNA was extracted from whole blood, thereafter amplified by polymerase chain reaciton, and digested by NcoI. We obtained and assessd RFLP of two alleles, TNFB1 which has a NcoI restriction site generating 555bp and 185bp fragments, and TNFB2 which lacks th NcoI restriction site. All data were analyzed by χ² test. Results: There were no significant differences in frequency of TNFB1/1, TNFB1/2, and TNFB2/2 between the schizophrenic patient and the control group. Alleric frequencies of TNFB1 and TNFB2 were significantly different between schizophrenic patient and control group. Conclusion: We found the possible association between alleles of TNFB and schizophrenia in this study. To clarify the influences of TNFB on schizophrenia, further systematic studies should be conducted.

Emphysematous cystitis is an uncommon disease in which bacterias produce gas within the bladder wall and surrounding tissue. Patients with diabetes, neurogenic bladder and chronic urinary tract infection are predisposed to the disease. It is usually caused by E.coli and Klebsiella. Severity of illness ranges from an asymtomatic condition to life threatening cystitis. Succesful management depends on early diagnosis with correction of underlying causes, administration of appropriate antibiotics, establishment of adequate bladder drainage and surgical excision of involved tissue when required. We report a case of 52-year-old woman who did not compain of symtoms of cystitis but epigastric pain, nausea, and vomitting. Emphysematous cystitis was revealed on the abdominal X-ray series incidentally. CT scans of the pelvis showed mottled gas bubble within the bladder. After treatment, the symtoms subsided and plain abdominal film showed no evidence of gas shadow in the pelvic cavity.
