척수강내 Bupivavacain에 첨가한 소량의 Neostigmin의 진통효과와 부작용

소금영,정종달,김병철,유벙식,안태훈,김훈정,임경준 조선대학교 2000 The Medical Journal of Chosun University Vol.25 No.2

Background : Spinal cholinergic receptor has been shown to have a antinociceptive action, an effect that can be mimicked by spinal cholinesterase inhibitor. Intrathecal injection of neostigmine cause analgesia and adverse effect in a dose-dependent pattern in the patients. The purpose of this study was to determine whether small doses of intrathecal neostigmine (10, 25 and 50 ㎍) produce analgesia and any side effects. Method : After getting informed consents, 60 patients scheduled for orthopedic surgery of lower extremities under spinal anesthesia were randomly assigned to one of four groups. Using dose-ranging design, patients received either normal saline or neostigmine l0, 25 or 50 ㎍ in a 1-㎎ solution of 5% glucose in normal saline with heavy bupivacaine 12 ㎎. Heart rate, blood pressure, degree of motor and sensory block were recorded. The assessment of postoperative analgesia included time to first rescue, total number of rescue medication and pain score on visual analog scale (VAS) at 1, 3, 6, 9, 12, 24 hour. Nausea and vomiting were assessed by using the visual analog scale at 24 hr postperatively and the incidence of them was recorded postoperatively. Result : There were no significant differences among the four groups in characteristics of spinal blocks. Compared to saline, neostigmine groups significantly prolonged time to first rescue medication and decreased total number of rescue medication and pain visual analog scale score, but incidence of nausea and 24hr nausea VAS score were not increased in neostigmine group compared to control group. Conclusion : These data in patients injected intrathecal neostigmine suggest that analgesia may occur at doses less than neostigmine 50 ㎍ and neostigmine 50㎍ has a better analgesia effect with fewer side effects than other doses for postoperative analgesia.

We proposed an efficient beam Propagation Method(BPM) algorithm for 3-D analysis, which can handle great amount of data on PC efficiently. The new algorithm, which is an expanded version of DuFort-Frankel algorithm for 3-D analysis, can reduce the number of computations for a given BPM analysis. The algorithm was applied to a rib-type directional coupler to find the same results as those from the coupled mode theory. 본 논문에서는 3차원의 연산을 위한 효율적인 3차원 광전파법을 제안하였다. 이는 기존의 2차원 구조에 많이 사용되었던 DuFort-Frankel법을 3차원으로 확장한 것으로서, 이 방법을 이용함으로써 광전파방법에서의 행렬연산의 횟수를 반으로 줄이여, 수치해석에 소요되는 시간을 최대 50%이상 감소시킬 수 있었다. 제안된 광전파법은 모드결합이론에 적용되었으며, 매우 정확한 결과를 얻었다.

<P><B>Abstract</B></P> <P>This study proposes a chemical treatment using 1,8-diazabicyclo[5,4,0]undec-7-ene (DBU), a well-known catalyst and non-nucleophilic base, to improve the conductivity of Ag nanowires (NWs)-networked transparent conductive films by removing the surface oxide of the wires. Upon DBU treatment, the sheet resistance of the films drops immediately and significantly, confirming its effectiveness for surface oxide reduction. Scanning and transmission electron microscopy analyses disclose that the wires do not show any sign of damage even after 1h-long exposure, an important benefit over other chemicals such as ammonia. We apply the method to excessively-oxidized Ag NWs via O<SUB>2</SUB> plasma and Cu NWs to further investigate the effectiveness of the method, confirming that the DBU treatment is an effective route to remove the surface oxide.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The chemical treatment using DBU improves the conductivity of Ag NWs films. </LI> <LI> The DBU treatment removes the surface oxide without harming the wires. </LI> <LI> The DBU treatment is effective in treating Cu NWs to some extent. </LI> </UL> </P>

An, Nan-Hee,Lee, Sang-Min,Cho, Jung-Rai,Lee, Byung-Mo,Shin, Jae-Hun,Ok, Jung-Hun,Kim, Seok-Cheol 한국토양비료학회 2014 한국토양비료학회지 Vol.47 No.6

Organic amendment practices can influence diversity and activities of soil microorganisms. There is a need to investigate this impact compared with other types of materials. This study was carried out to evaluate the long term effects of chemical and organic fertilizer on soil microbial community in upland field. During the last 11 years green manure, rice straw compost, rapeseed cake, pig mature compost, NPK, and NPK + pig mature compost were treated in upland soil. Organic fertilizer treatment found with high bacterial colony forming units (CFUs) as compared to chemical and without fertilizer treatment. There was no significant difference in the actinomycetes and fungal population. The average well color development (AWCD) value was the highest in green manure and, the lowest in without fertilizer treatment. Analyses based on the denaturing gradient gel electrophoresis (DGGE) profile showed that rice straw compost and pig mature compost had a similar banding pattern while rapeseed cake, NPK, NPK + pig mature compost and without fertilizer treatment were clustered in another cluster and clearly distinguished from green manure treatment. Bacterial diversity can be highly increased by the application of organic fertilizer while chemical fertilizer had less impact. It can be concluded that green manure had a beneficial impact on soil microbial flora, while, the use of chemical fertilizer could affect the soil bacterial communities adversely.
