정종태 濟州大學校 農科大學 動物科學硏究所 1993 動物科學論叢 Vol.8 No.1

Pain rcflex and anesthetic state in swine with xylazine epidural anesthesia were observed. In xylazine epidural anesthesia, dosages of 0.50mg/kg BW for analgesia of perineal region and 0.75mg/kg for analgesia of low abdominal wall were required. Regional anesthesia was induced 5-20 min after epidural injection of xylazine and recovered 90-120 min after administration. The results indicated that xylazine as an epidural local anesthetic was useful in swine.

정종태 제주대학교 1994 논문집 Vol.39 No.-

복강내 유착은 개복술의 주요한 합병증으로 이를 조기에 진단하면 계속되는 후유증이나 재수술시 적절한 절개부위를 선택할 수 있다. 본 실험은 개에서 위와 장의 복벽유착을 진단하기 위하여 수행하였다. 개의 위나 장을 유착시킨후 기복을 시키지 않고 일반적인 방사선촬영을 실시한 경우에는 유착을 확인할 수 없었다. 기복을 실시한 개에서는 앙와자세에서 측위로 방사선을 수평조사하여 얻은 결과에서 위나 장이 복벽에 유착되었음을 확인할 수 있었다. 이상의 결과 개에서 위나 회장이 복벽에 유착되었을때 기복을 실시한 후 유착이 존재하는 부위를 체축의 상부로하여 방사선촬영을 실시하면 유착의 진단이 가능하다고 사료된다. The abdominal adhesions are important sequelae in laparotomy. If it is early diagnosed, the prevention of proceeding sequelae of the adhesions and choice of better incision site will be possible. This study was performed to diagnose gastric and intestinal adhesions to abdominal wall in dogs. In case of usual radiography it is impossible to diagnose gastric or intestinal adhesions to abdominal wall. But with lateral view, horizontal beam, supination after pneumoperitoneum it is possible to diagnose the adhesions.

The expression of pro-apoptotic molecules, p53 and Bax, in the spinal cord of rats with experimental autoimmune encephalomyelitis (EAE) was examined. Apoptosis was confirmed by the terminal deoxynucleotidyl transferasemediated dUTP nick end-labeling (TUNEL) method. TUSEL (+) apoptotic cells were mainly either ED1 (+) macrophages or T-cells in the parenchyma of E N . Western blot analysis showed that both p53 and Bax expression significantly ( p < 0.01) increased in the spinal cords of EAE rats at the peak stage, and thereafter declined. An immunohistochemical study showed that inflammatory cells (notably T cells) in the parenchyma express p53 and Bax, while brain cells, includng neurons and glia, were devoid of these nuclear staining of these molecules. The nuclear expression of p53 largely matches apoptotic cells in the parenchyma of EAE. These finchngs suggest that pro-apoptotic molecules, p53 and Bax, may play an important role in eliminating T cells in the parenchyma in EAE.

이태종,정수환 경북대학교 산업기술연구소 1988 産業技術硏究誌 Vol.16 No.-

The accurate prediction of fluid thermodynamic properties and their efficient computation become increasingly important in present industrial processes and their design simulation. The objective of this work is to investigate the effect of small variations of the characterization parameters on errors of predicted properties within a three-parameter corresponding states correlation framework. The thermodynamic properties of LNG pure components are calculated from Benedict-Webb-Rubin-Starling equation of state. Test discloses that a slight change of orientation parameter has negligible effect on either predicted densities or enthalpies but is found to be very sensitive on vapor pressure of all LNG components except methane and nitrogen. Consequently, an attempt to decrease the errors in predicted properties of vapor pressure without increasing the errors of other predicted properties of the same component was succeeded for ethylene, propylene and isopentane. Improved orientation parameters were obtained for those unsaturated hydro-carbons.

Operators of hospital sterilizers who use ethylene oxide(EtO) were studied to determine the exposure of EtO level and the frequency of sister chromatid exchanges(SCEs) from June 12 to July 20, 1997. To evaluate SCEs in the peripheral blood cells, we selected 22 workers at the central supply room of 4 university hospitals and 22 unexposed workers at the same hospitals according to match sex, age, and smoking habit and also did questionnaires. The mean air concentrations(8-hr TWA) of EtO at 4 university hospitals were less than 1 ppm. The SCE frequencies in exposed workers to EtO and controls were normally distributed. The SCE frequencies in exposed workers to EtO and controls were 6.42±0.63, 5.86±0.69, respectively and their differences were statistically significant(p=0.0093). But there were no statistically significant differences in smoking, alcohol intake, coffee drinking. Especially smokers who exposed to EtO were increased SCE statistically significant than the exposed group who did not smoke.

본 연구는 급성호흡부전환자를 치료하기 위하여 사용되고 있는 혈관 내 폐 보조장치의 기체전달을 향상시키기 위하여 중공사막에 진동기법을 사용하여 기체전달을 향상시키고자 시도하였다. 그리고 혈관 내 폐 보조장치를 정맥에 삽입하기 전, 혈관 내 폐 보조장치의 설계조건을 실험적 모델을 통하여 기체전달을 예측할 수 있는 예측식을 만들고자 하였다. 실험결과, 본 연구에서는 진동기법이 기체전달을 향상시키는데 효과적임을 확인할 수 있었다. 뿐만 아니라, 충진율과 가징 주파수의 함수관계를 이용하여 기체전달을 예측 할 수 있었다. 실험에 의하여 얻어진 결과는 예측식에 의하여 얻어진 결과와 유사한 결과를 얻었다. 그러므로 본 연구에서는 충진율과 가진 주파수의 함수를 이용하여 VIVLAD의 기체전달을 예측할 수 있었다. In this paper, we tried to improve gas exchange of the vibrating intravascular lung assist device(VIVLAD) using vibrating method in the hollow fiber membrane, for the patients suffering from acute respiratory distress syndrome(ARDS). And we tried to formularize prediction equations to make a prediction about gas transfer for designing intravenous artificial lung assist device, and designed modules under various conditions were studied through an experimental modeling before inserted the artificial lung assist device into as venous. As a result, we are convinced that vibration method is very useful for the has transfer increasing. Also, we can estimate the gas transfer as a function of the packing density and excited frequencies. The gas transfer obtained from the experiment was similar to that from the prediction equation, confirming the usefulness prediction equation. Therefore, we can estimate the gas transfer of the VIVLAD as a function of the packing density and excited frequencies.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.
