Background: Continuous air leakage through chest tube after lung surgery may increase pt's hospital stay and lead to many complications including empyema etc. Chemical pleurodesis has frequently been used for prevention of air leakage. Therefore, we performed chemical pleurodesis using diluted fibrin glue in patients with continuous air leak-age and observed the effects and efficiency of treatment. Material and Method: From September, 2001 to August, 2005, 16 patients whose continuous air leakage lasted more than 7 days underwent chemical pleurodesis with diluted fibrin glue. The effects of treatment, complications and recurrences were reviewed. Dissolved fibrinogen 1.0 g and aprotinin 500,000 KIU were mixed in a 50 cc syringe (Mixed solution A). And dissolved thrombin 5,000 IU and Calcium chloride 600 mg were mixed in a 50 cc syringe (Mixed solution B). Cefazolin 1.0 g was mixed in a 50 cc syringe (Mixed solution C). Rubber tube was inserted between the chest tube and the collecting bottle. An inserted rubber tube was positioned 60cm above the patient and forming a loop appearance was done. Mixed solutions A, B and C were injected into the highest rubber tube. Results: Continuous air leakages disappeared in all f6 patients at next day. Chest tubes were removed after 3 days in all patients. Complications were chest pain in 12 patients (75%), leukocytosis in 14 patients (88%), fever and chill in 14 patients (88%). All complications were transient and disappeared without specific treatment. Conclusion: Our findings demonstrated that diluted fibrin glue chemical pleurodesis was effective in patients with continuous air leakage lasting more than 7 days. Diluted fibrin glue chemical pleurodesis had good results with acceptable complications. long term follow-up is necessary to evaluate the accurate effects of treatment and recurrence in a large number of patients.

도시생활폐수에 포함되어 배출되는 폐열을 열펌프의 열원으로 하는 폐수열원 열펌프 시스템에 대한 관심이 오래전부터 집중되어 있었지만 폐수 열교환기 전열면의 오염문제 때문에 실용화에 커다란 진전을 보지 못하고 있다. 한편, 생활페수는 비교적 저온이기 때문에 열펌프시스템의 설계에 특별한 주의를 기울여야 한다. 즉, 이러한 폐열을 회수하여 유효에너지 자원화 하기 위한 신기술이 이루어 져야한다. 본 연구에서는 이러한 점을 감안하여 도시생활 폐수열의 이용가능성을 검토하고 이를 열원으로 하는 열펌프의 개발을 위한 폐수 열교환기의 모델을 개발하였다.

We applied our technique of selective bronchial suctioning (SBS) for the treatment of atelectasis after resection surgery of lung in four patients with refractory atelectasis who were treated successfully. We considered that SBS using hydro-catheter insertion under local anesthesia above fourth tracheal ring is the effective technique for the treatment of refractory atelectasis when conventional respiratory therapy is not effective and a bronchoscopist is not available.

최근 우리나라에서 수처리(음용수, 오폐수 포함)분야에서 막분리 공정에 대한 관심도가 비등하고 있다. 신기술의 등장은 기존 기술의 보완내지는 대체를 통하여 자동화, 경제성, 처리수질, 제어방식 등에서 큰 변화를 줄것임에 틀림이 없다. 그러나 모든 신기술이 다 그러하지만 막분리기술도 그 정체를 바로알고 현명하게 채택 활용해야지 과도한 기대감이나 불필요한 저항감에서 신기술의 장점을 살리지 못하면 큰 손실이 아닐 수 없다. 본 난에서는 독자들의 수처리용 막분리기술에 대한 이해를 돕기 위하여 앞으로 3회에 걸쳐 1회: 막과 막분리 공정의 기본 설명, 2회: 막과 정수처리, 3회 막과 오/폐수처리의 순으로 연재할 것이다. 독자들의 이해를 돕기위하여 평이한 용어와 문장을 쓰려고 노력하였으며 3회의 연재가 이 기술의 정체를 파악하는데 도움이 되길 기대한다.

Industrial wastewater often contains a number of recalcitrant organic contaminants. These contaminants are hardly degradable by biological wastewater treatment processes, which requires a more powerful treatment method based on chemical oxidation. Advanced oxidation technology (AOT) has been extensively studied for the treatment of nonbiodegradable organics in water and wastewater. Among different AOTs developed up to date, ozonation and the Fenton process are the representative technologies that widely used in the field. Based on the traditional ozonation and the Fenton process, several modified processes have been also developed to accelerate the production of reactive radicals. This article reviews the chemistry of ozonation and the Fenton process as well as the cases of application of these two AOTs to industrial wastewater treatment. In addition, research needs to improve the cost efficiency of ozonation and the Fenton process were discussed.

The patients with primary lung cancer who have symptoms of angina pectoris commonly have underwent coronary artery bypass grafting (CABG) prior to lung resection. Recently, there are attempts to conduct simultaneous operation of CABG and lung resection to reduce disadvantages of staged operation, such as repeated general anesthesia, two wound incisions and delay of lung operation. These attempts generally report good results. Three patients underwent lung resection and CABG simultaneously, and had good post operative status without recurrence of cancer and angina pectoris. We conceive these as worthy cases to report.
