Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

The current study evaluates the capacity of eugenol to regulate immediate allergic reaction by control of histamine release. Administrations of eugenol (1 M/kg. i.p.) at 60 min before and 5.10 min after the compound 48/80 treatment (8 mg/kg.i.p.) were shown the mortality rates as 0.44.4. and 77.8%. respectively. A 60 min before administered group revealed a singificant inhibition of serum his-tamine release compared with those of 5 and 10 min after the compound 48/80 injection. Eugenol (6-48mM) was also showed a dose-dependent activity on the compound 48/80-induced histamine release from the highly purified population of Alcian Blue-positive peritoneal mast cells. These results indicate that in vitro treatment with exogenous eugenol inhibited the active response of mast cell populations and modulated its characteristics.

( Tae Wook Kim ),( Jong Hyuck Kim ),( Nam Eun Bae ),( Hyung Seok Seo ),( Young Soo Baik ),( Jeong Beom Lee ),( Hun Mo Yang ),( Young Ki Min ) 한국운동영양학회 2012 Journal of exercise nutrition & biochemistry Vol.16 No.4

This study investigated whether the recruitment of activated sweat gland density during passive heating [immersion of the lower body into hot water, 41℃ for 30 min (PH), room temperature 23 ± 0.5℃ with 60 ± 3% relative humidity] is different in endurance-trained (Trainee), compared with that of untrained subjects (Control), as indicated by VO2max. Eight trainees and seven control female subjects (38.31 ± 4.91 ml·kg-1·min-1 and 31.8 ± 0.92 ml·kg-1·min-1, respectively, p < 0.01) were similar on all other physical characteristics. To compare the changes between the trainees and controls, serum cortisol and prolactin (PRL), tympanic temperature (TYMP), local activated sweat gland density (L-ASGD) and the mean whole body sweat loss volume (M-WBSLV) changes were measured after PH. The cortisol was significantly higher (p < 0.05) and the PRL tended to be higher in the Trainee than in the Control. The TYMP increased more in the Trainee than in the Control (p < 0.001). The L-ASGD showed a higher tendency in the Trainee than in the Control, there was a significant difference in the mean activated sweat gland density (p < 0.01) and the L-ASGD was significantly correlated with the VO2max (p < 0.001). The M-WBSLV was significantly higher in the Trainee (p < 0.001) and significantly correlated with the VO2max (p < 0.001). The results suggest that in humans, a high aerobic capacity is associated with a greater recruitment of activated sweat glands, whole body loss of volume and TYMP. Therefore, the decline in the heat loss responses, due to decrease in maximal oxygen consumption, may be masked by repeated endurance exercise training.

김상태,배진호,김상범,임승운,민병상,신영덕 대한마취과학회 2000 Korean Journal of Anesthesiology Vol.38 No.3

Background : COPA (cuffed oropharyngeal airway) is a convenient device for airway management in patients undergoing general anesthesia for elective surgery in supine position. It causes less pharyngeal trauma than LMA(Laryngeal mask airway). The purpose of this study was to compare the effect of COPA with and without muscle relaxant. Methods : Forty patients with ASA physical status I and II for elective surgery were randomly assigned to two groups. Anaesthesia was induced with propofol (2 mg/kg) and vecuronium (1.5 mg/kg) and was administered intravenously in Group I but not in Group II. Mask ventilation was done for 5 min with 0: 5 L/min. COPA was placed and heart rate, and systolic, mean, diastolic blood pressure and peak inspiratory pressure were measured at 1 min interval for 5 min. Anaesthesia was maintained with pro- pofol 150 ㎍/kg/min, fentanyl 1 ㎍/kg/hr, O_2 2 L/min and N_2O 2 L/min. Results : There were no significant differences between Group I and Group II in heart rate, systolic, mean and dstolic blood pressure. PIP (Peak inspiratory pressure) was increased and hiccups occurred significantly (p $lt; 0.05) in Group II. Complete airway obstruction occurred in one patient of Group I and severe coughing, body movements and gagging occurred during induction and insertion in Group II. conclusions : With the use of appropriate muscle relaxant, we can use COPA without increased inspiratory pressure or significant complication.

Kim, Jong Seok,Park, Yeong Min,Bae, Mun Ki,Kim, Chi Whan,Kim, Dae Weon,Shin, Dong Chul,Kim, Tae Gyu World Scientific Publishing Company 2018 Modern physics letters. B, Condensed matter physic Vol.32 No.20

<P>In this study, diamond thin films were deposited on tungsten carbide tools using surface-wave plasma-enhanced chemical vapor deposition (SWP-CVD). To eliminate the adverse effects of cobalt on the diamond deposition process, the cobalt was removed from the surface of the tools by etching with Murakami’s reagent for various times (30, 60, and 120 min). The cutting performance of the untreated and the diamond-coated WC tools was examined by performing cutting test on carbon fiber-reinforced plastic (CFRP). The results showed that all the diamond-coated tools exhibited great improvement on the durability and wear resistance compared to the uncoated one. In addition, the diamond-coated tool lift time is found to be proportional to the etching time. An increase more than twofold has been achieved when the etch time was increased from 30 min to 120 min.</P>

불투수성 지역의 강우유출수에 대한 비점오염물질의 초기유출현상 분석

안태웅(Tae Ung Ahn),범봉수(Bong Su Bum),김태훈(Tae Hoon Kim),최이송(I Song Choi),오종민(Jong Min Oh) 大韓環境工學會 2013 대한환경공학회지 Vol.35 No.9

본 연구에서는 불투수성 지역에서 강우시 비점오염원 유출특성을 파악하고, 다양한 해석방법을 통하여 비점오염물질의 초기유출현상을 규명하고자 하였다. 불투수성 지역에서의 강우사상 특성은 강우강도의 영향을 많이 받는 것으로 나타났으며, 강우강도가 크면 초기유출현상이 뚜렷하게 나타나는 것으로 나타났다. 또한 선행무강우일수에 의해서 비점오염물질의 농도차가 큰 것으로 나타나, 이에 대한 대책 마련이 필요할 것으로 판단된다. 비점오염원의 초기유출에 의한 감소율(DR) 평가 결과, 강우시 불투수성 지역에서의 비점오염 유출특성은 건기시 불투수면에 집적되어 있던 비점오염물질이 초기강우에 의해 높은 농도로 유출되는 경향을 보였기 때문에 초기강우로 인한 비점오염물질에 대한 대책을 마련하는 것은 중요하고, 이와 관련하여 비점오염 처리시설에 대한 용량 산정에 대한 평가도 필요할 것으로 판단된다. 초기유출에 의한 감소율(DR)경향 분석은 비점오염물질에 대하여 감소율(DR) 50%를 기준으로 조사지점별 강우유출시간을 분석하였는데, TSS는 15~60min으로 나타났으며, 유기물질은 30~90 min으로 나타나는 경향을 보였지만 강우유출이 끝날 때까지도 감소율(DR)이 50% 이하인 특성도 나타났다. 이를 근거로 하여 향후 구조적 BMPs 시설 설계 시 참고자료로 활용할 수 있을 것으로 판단된다. In this study, trend analysis was performed by various runoff analysis method of Non-point Pollution Source(NPS) at the impervious area. The characteristics of rainfall at impervious area appeared to be influenced by rainfall strength and it appeared that first flush phenomenon occurs often if rainfall strength acts largely. It is judged that the measure is required to be prepared against that now that concentration difference of non-point pollution source appeared to be big by precedent number of days of no rainfall. As the result of calculating Decrease Rate (DR) by first flush of non-point pollution source, it is judged that it is important to prepare the measure against the pollutants about initial rain and it is necessary to calculate the capacity of non-point pollution source processing facilities regarding that now that the non-point pollution source integrated at impervious area showed the characteristics that are flowed out in high concentration by initial rain in case of non-rainfall considering the characteristics of non-point pollution source at impervious area. When taking 50% of non-point pollution source as the standard for decrease rate that was evaluated previously, it appeared as 15~60 min in case of TSS and it appeared as 30~90 min in case of organic compound, but the characteristic whose decrease rate is below 50% also appeared even till rainfall-runoff ends. Based on that, it is judged that it could be used as the reference when designing the structural BMPs facilities later.
