Background: Shoulder horizontal adduction (HA) is performed in many activities of daily living. The limited range of motion (LROM) of HA is affected by the tightness of the posterior deltoid, infraspinatus, teres major, and posterior capsule of glenohumeral joint. The LROM of shoulder HA contributes to excessive scapular abduction. Objects: The aim of this study is to compare the scapular abduction distance and three dimensional displacement of the scapula during shoulder horizontal adduction between subjects with and without the LROM of shoulder HA. Methods: 24 subjects (12 people in LROM group and 12 people in normal ROM group) participated. Subjects with less than 115° of HA ROM were included in LROM group. Shoulder HA was performed 3 times for measuring scapular abduction distance and three-dimensional displacement of the scapula. Tape measure was used for measuring scapular abduction distance. Scapular abduction distance was normalized by dividing the scapular size. Polhemus Liberty was used for measuring the three dimensional displacement of the scapula. Results: Normalized scapular abduction distance was significantly greater in LROM group than normal ROM group (p<.001). Three-dimensional displacement of the scapula during shoulder HA was greater in LROM group than normal ROM group (p<.05). Conclusion: LROM group had a greater scapular abduction and three-dimensional displacement of the scapula during shoulder HA compared to normal ROM group.

Background: From many previous studies, Pulmonary hypertension is the known independent predictive factor of the mortality in COPD. Also pulmonary hypertension is the major cardiovascular complication of COPD and is associated with the progression to cor pulmonale and poor prognosis. Author want to analyze the correlation between pulmonary hypertension and the severity of COPD which are classified by forced expiratory volume in one second, and the extent of progression to corpulmonale. Methods: Retrospectively we investigated the medical records of 118 patients with COPD who had pulmonary function test and echocardiogaphy more than one times during one-year follow-up (from June, 2005 to May, 2006) at respiratory division in chosun university hospital, and then 50 patients were enrolled in this study. We classified the severity from FEVl in pulmonary function test based on the GOLD guideline, also this was comparably analyzed with RVSP, RVIDd, Visual Grading from echocardiography. Results: 16 patients out of 50 were classified as moderate severity, 25 patients were severe, and 9 patients were very severe group. RVSP was higher in more severe groups than less severe groups but when it comes to pulmonary hypertension that RVSP is over 35 mmHg, there was no valid difference lies in those groups. As FEVl decreases RVSP and RVIDd increases, and observed relationship between RVSP which was classified as below 35 mm and above 35 mm groups and visual grading which was classified as normal and dilatated groups revealed valid correlation, Conclusion: As pulmonary function decreases, progression to pulmonary hypertension and cor pulmonale increases but there was no remarkable difference of prevalence in above moderate severity groups. 연구배경 폐고혈압은 이전의 많은 연구에서 만성폐쇄성폐질환에서 독립적인 사망의 예측인자로 알려져 있다. 또한 폐고혈압은 만성폐쇄성폐질환의 주요한 심혈관계 합병증이며, 폐성심으로의 진행 및 불량한 예후와도 관련되어 있다. 이에 저자는 폐고혈압과 1초간 노력성호기량으로 분류되는 만성폐쇄성폐질환의 중증도 및 폐성심으로의 진행 정도를 비교 분석하여 이들의 상관관계를 밝혀보고자 한다. 방법 2005년 6월부터 2006년 5월까지 1년 동안 본 병원 호흡기 내과에서 폐기능검사와 심장초음파 검사를 각각 1회 이상 시행한 적이 있는 118명에 한하여 의무기록을 후향적으로 조사하여 이 중에서 50명을 대상으로 하였다. 폐기능검사 시행 결과 얻은 1초간 노력성호기량을 바탕으로 GOLD guideline에 따라 중증도를 분류하였으며 이를 심초음파 시행 결과 얻은 우심실수축기압, 확장기말 우심실내부간격, 시각등급과 비교분석하였다. 결과 대상 환자 50명중 16명은 중등증, 25명은 중증, 9명은 최고중증 그룹으로 분류되었다. 우심실수축기압은 중증도가 높은 그룹에서 낮은 그룹에 비해 더 높게 나타났으나 폐고혈압에 해당하는 우심실수축기압이 35 mmHg이상인 환자에 있어사는 각 그룹간에 유의한 차이를 보이지 않았으며, 확장기말 우심실내부간격, 시각등급 또한 중증도와 유의한 차이를 보이지 안항ㅆ다. 1초간 노력성호기량이 감소함에 따라서는 우심실수축기압, 시각등급은 증가하였으며 우심실수축기압을 35mmHg 미만과 이상인 그룹으로, 시각등급을 정상과 확장이 있는 그룹으로 분류하여 비교한 결과에서는 유의한 상관관계를 나타냈다. 결론 폐기능이 감소할수록 페고혈압 및 폐성심으로의 진행이 증가하였으나 폐기능검사에서 중등도 이상의 그룹에서 유병률의 차이는 크지 않았다.

RNA 중합효소의 C-terminal은 YSPTSPS의 반복적인 아미노산 서열을 갖고 있으며, 이들의 인산화는 전사의 개시, 중합, 또는 종결단계에 중요하다고 알려져 있다. 본 연구에서는 이러한 RNA 중합효소의 인산화가 mRNA의 3' end processing에 미치는 영향을 조사하였다. C-terminal domain (CTD) of RNA polymerase Ⅱ contains a repeated heptameric sequence (YSPTSPS) which is phosphorylated at serine 2 and 5. Phosphorylation of CTD in elongating RNA polymerase Ⅱ has been suggested to play a role in transcriptional initiation, elongation or termination. In the present study, we investigated the effect of RNA polymerase Ⅱ CTD phosphorylation on the 3' end processing of mRNA.

권세훈,김형호,강지인,하재하,한경택,이재록,김동민,권용은,윤성호,이승일 朝鮮大學校 附設 醫學硏究所 2007 The Medical Journal of Chosun University Vol.32 No.1

Scrub typhus is a potentially fatal infectious disease caused by the organism Orientia tsutsugamushi. Clinical manifestations are fever, skin rash, eschar and varying degree of respiratory distress. The pleural effusion in scrub typhus is rare and secondary to the destruction of vascular endothelium. Because the respiratory symptoms are generally mild and the pleural effusion in scmb typhus is rare than in interstitial pneumonia, there are few comments about the characteristics of scmb typhus with pleural effusion. So we made the comparative study of scmb typhus patients between with pleural effusion and without pleural effusion. 연구배경 치명적일 수 있는 감염질환 중 하나인 쯔쯔가무시중(Scrub typhus)에서 드문 흉막삼출을 동반한 환자에 대한 고찰은 다른 문헌에서도 자주 언급되지 않았다. 따라서 본 저자들은 흉막삼출이 있는 경우와 없는 경우에 따른 쯔쯔가무시중 환자들을 비교하고자 하였다. 방법 2003년에서 2006년까지 조선대학교 병원 내과에 입원중인 환자 중 쯔쯔가무시중 진단을 받은 총 109명의 환자를 대상으로 하여 흉부 X선 검사 및 혈청학적 검사(CPK, LDH, ESR, CRP, AST, ALT, ADA), 혈액학적 검사(WBC, PLT) 및 백분율 검사등을 실시하였다. 결과 흉막삼출이 있는 환자들의 경우 흉막 삼출이 없는 환자들에 비해 ESR 수치가 통계학적으로 의의있게 높았다(p-vaule < 0.05). 결론 흉막삼출 유무에 따른 쯔쯔가무시중 환자간의 비교에 있어 ESR 수치가 통계학적인 의의를 가졌다.

연구배경: 갑상선암은 다른 조직에 발생한 암에 비해 비교적 천천히 자라므로 대부분 예후가 양호하지만, 일부에서는 주위 조직으로 침윤하거나 혹은 원격 전이로 인하여 치명적인 결과를 초래할 수 있다. 갑상선전절제술 및 131^I 제거술 후 경과 관찰시 갑상선암의 재발과 전이의 진단에 있어 131^I 스캔과 혈청 Tg의 측정이 현재 임상에서 가장 많이 이용되고 있으나 이 방법에는 여러 가지의 결점이 있다. 최근 Tg mRNA에 대한 RT-PCR법을 이용한 여러 연구결과는 131^I 스캔과 혈청 Tg 측정의 결점을 보완할 수 있는 좋은 보조적인 진단법으로 이용할 수 있을 가능성을 제시하였다. 이에 말초혈액에서 측정한 Tg mRNA에 대한 RT-PCR법이 갑상선 절제술 및 방사성요드 치료 후 갑상선암의 재발 및 전이 유무의 진단에 유용한가를 알아보고자 이 연구 시행하였다. 방법: 분화된 갑상선암으로 진단된 후 갑상선전절제술을 시행받고 방사성요드 치료를 받은 환자 중 현재까지 한차례에 이상 추적 방사성요드 전신 스캔을 시행하고 추적관찰이 가능했던 유두선암 35예, 여포선암 5예를 대상으로 연구를 시행하였다. 대상군은 131^I 스캔 소견상 음성인 군(Group Ⅰ), 잔여조직이 있는 군(Group Ⅱ), 국소전이가 있는 군(Group Ⅲ), 및 원격전이 군(Group Ⅳ)으로 구분하였다. 정상 대조군은 갑상선질환이 없는 10예의 건강인으로 하였다. 대상환자의 말초혈액을 이용한 Tg mRNA에 대해 특이적인 primer를 이용하여 RT-PCR 및 nested RT-PCR을 시행하였다. 결과: 본 연구 결과는 다음과 같다. 1) 131^I 스캔 소견상 음성인 군 21예 중 1예에서 Tg가 양성소견을 보였다. Anti Tg Ab가 양성인 4예 모두 Tg가 음성을 보였다. 잔여조직이 있거나 국소전이 및 원격전이를 보인 군 19예 중 Tg가 양성인 경우는 4예였으나, Tg mRNA는 전예에서 양성이었다. 2) 131^I 스캔에서 국소 및 원격전이 소견을 보인 8예 중 4예에서 Tg가 음성으로 131^I 스캔과 혈청 Tg 사이에 불일치 소견을 보였다. 3) 말초혈액에서 특이적인 primer를 이용하여 RT-PCR 및 nested RT-PCR을 시행한 결과 대상군 40예 및 정상 대조군 10예 모두에서 Tg mRNA가 양성을 보였다. 결론: 본 연구에서 갑상선 절제술 및 방사성요드 치료 후 갑상선암의 재발 및 전이 유무를 평가함에 있어 역전사 중합효소 연쇄 반응법을 이용한 Tg mRNA 측정의 의의는 재평가되어야 한다고 생각된다. Background: Differentiated thyroid cancer is the most common endocrine malignancy. Despite advances in the treatment of thyroid cancer, disease recurrence and metastasis may occur in as many as 20% of patients, and so continues to pose major problems in its clinical management. Serum thyroglobulin (Tg) measurements, by immunoassay, are used to detect residual or recurrent thyroid cancer following thyriod ablation. However, the usefulness of immunoassay is limited by both the requirement for thyroid hormone withdrawal, to attain optimal test sensitivity, and interference by the antithyroglobulin antibody (Anti-Tg Ab). Recent studies have reported the clinical usefulness of reverse transcription-polymerase chain reaction (RT-PCR) detection of Tg mRNA in the peripheral blood of patients with differentiated thyroid carcinomas. We performed this study to evaluated the usefulness RT-PCR of Tg mRNA in peripheral blood of patients with thyroid carcinoma following a total thyroidectomy and radioiodine ablation therapy. Methods: Forty cases that underwent a total thyroidectomy and radioiodine ablation therapy were included in this study. Of the 40 patients, 35 were papillary carcinomas and 5 were follicular carcinomas. Ten normal control subjects were also studied. Tg mRNA was extracted. Then RT-PCR and nested RT-PCR, were run with specific Tg primers. Concurrently, DNA sequencing of the isolates was carried out to prove the isolates were identical to the nucleotide sequence of the Tg. Results: The Tg was detected in 4 of 19 patients, with either a residual thyroid bed, or metastasis, on a 131^I whole body scan and in 1 of 21 patients with a negative radioiodine scan. Surprisingly, the Tg mRNA was detected in all the patients and normal controls. Conclusion: From our results we can not recommend Tg mRNA, detected by RT-PCR in peripheral blood, as a tumor marker superior to that of the Tg serum level. We consider an intensive re-evaluation of the method is required before considering its clinical applications (J Kor Soc Endocrinol 17:501∼513, 2002).

This study aims to develop using a continuous removal of organic and settling solid(CROSS) to increase the efficiency of aeration system for wastewater treatment. To solve many problems of the conventional activated-sludge process, authors suggested a new CROSS model in conjunction with aeration systems in 1996. This system is characterized by utilizing an intensive aeration pipe with inlets at the lower portion and outlets at the higher portion in an aeration tank. Through the experiments on CROSS process, the average removal efficiences of BOD, COD_(Mn), SS, T-N and T-P were showed 98.8%, 93.9%, 98.0%, 71.3% and 49.8%. The average DO (Dissolved-Oxygen) concentration was constantly maintained at 8.0 mg/L by the intensive aeration which was accompanied by rapid reduction of BOD. Degradation of the organic matters in sewage then continued for the whole aeration period. The process demonstrated that it was very adaptive without seeding and returning the sludge. Compared to the activated sludge system, the system was very flexible for the continuous flow treatment. This preliminary assessment showed that the porous media in CROSS reactor is viable for the sewage treatment, since the porous media under the intensive aeration achieves acceptable effluent quality.
