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.

본 연구는 여러 가지 근관세척액(NaOCl, CHX, EDTA)과 구강세정제로 사용되는 Listerine을 근관감염균주인 Porphyromonas gingivalis와 Enterococcus faecalis를 상대로 항균효과를 비교하고 Listerine이 근관세척액으로 사용가능한지를 확인하고자 시행하였다. 본 연구에서는 Porphyromonas gingivalis ATCC 3327과 Enterococcus faecalis ATCC 29212의 표준균주를 사용하였다. 실험을 위한 근관세척제로 0.1%, 0.2%, 1%, 2% Chlorhexidine(CHX)과 0.5%, 1%, 2.5%, 5.25% NaOCl, 0.5M EDTA(18.6% EDTA). 그리고 Listerine원액을 이용하였다. 항균효과의 비교는 액체배지상에서 균주의 혼탁도와 한천 확산법을 이용한 억제대 비교로 하였다. 모든 실험군은 대조군과 비교시 근관내 균주에 항균성을 나타냈다(p < 0.001). 모든 농도의 NaOCl, CHX, 그리고 EDTA는 실험균주에서 높은 항균성을 보였다. 모든 실험에서 Listerine은 다른 근관세척제에 비해 낮은 항균성을 보였다. 결론적으로, Listerine이 E. faecalis와 P. gingivalis에 대해 항균성을 보이나, 일반적으로 사용되는 근관세척 액에 비해서는 현저히 낮은 항균성을 나타냄으로 근관세척 액으로 사용은 적합하지 않음을 나타냈다. The purpose of this study is to compare the antibacterial effect of Listerine on two microorganisms (P. gingivalis and E. faecalis) with various root canal irrigants (NaOCl, CHX, EDTA) and to identify possibility of using Listerine as a root canal irrigant. Porphyromonas gingivalis ATCC 3327 and Enterococcus faecalis ATCC 29212 were used in this experiment. For the test irrigants, 0.5%, 1%, 2.5%, 5.25% NaOCl, 0.1%, 0.2%, 1%, 2% CHX, 0.5M EDTA (18.6% EDTA) and Listerine were prepared. Distiled water was used as control. Two methods-1) Comparison of turbidity in broth and 2) Agar diffusion test-were used to determine the extent of antibacterial effect of Listerine and to compare it with that of NaOCl, CHX, and EDTA. All solutions tested were effective against two bacterial strains compared with control (p < 0.001). Any concentration of NaOCl, CHX, and EDTA showed similarly high effectiveness against all bacterial strains. In all experiment, Listerine showed significantly low antibacterial effect compared with the other root canal irrigants (p < 0.05). In conclusion, the results reflect remarkably low antibacterial effect of Listerine as compared with root canal irrigants in general so it is not suitable for the root canal irrigant.

N/A Objectives : The purpose of this study is to establish animal model of extracorporeal membrane oxygenation (ECMO) system that uses membreane type oxygenator and circulation circuit of umbilical artery and vein. Blood gas and hemodynamic changes in the fetal goat undergoing ECMO were also evaluated. Methods : Total 15 pregnant goat had been used to perform extrauterine fetal incubation using ECMO through umbilical artery and vein. Cesarean-section was performed to pregnant goat (35 kg) of 120-130 days of gestation to insert catheters (8 Fr) into the umbilical artery and vein. The tip of inserted catheter's the other end was connected with the circuit system including membrane type oxygenator (Polystan) and roller pump. A total of 300 ml of blood was drawn from donor nonpregnant goat and primed into circuit on the day of surgery. The goat fetus was immersed in a chamber filled with artificial amniotic fluid to monitor blood flow dynamics and blood gas was analyzed. Results : The ECMO system using umbilical cord in the extrauterine incubation of fetal goat was developed and maximum survival of goat fetus was 34.5 hrs (mean survival was 856.6±688 min). Oxygen tension (PO2) in umbilical artery and vein were 20.53±2.54 mmHg, 31.03±13.03 mmHg and oxygen saturation (SO2) in umbilical artery and vein were 46.61±18.14 mmHg, 71.56±15.39 mmHg. Mean blood flow was 176±62 ml/min/kg. Conclusion : We suggest that our experimental model as an extrauterine fetal research could be a reasonable method in future advanced studies. However, longterm survival of extrauterine fetus needs more suitable hemodynamic and blood gas condition supported by further researches.

정맥내 평활근종증은 병리학적으로는 양성 질환이나 진행 양상은 악성으로 모든 종양의 적출술이 시행되어야 하며, 자궁적출술시 병리학적으로 정맥내 평활근종증을 진단받은 경우 정기적인 검사를 통해 종양의 재발이나 하대정맥과 심장내로의 연장을 확인하여야 한다. 우측 심장내 종양이 발견된 경우는 점액종을 포함한 원발성 심내 종양 외에도 다른 원인 질환을 확인하여야 하며, 반드시 정맥내 평활근종증을 감별진단하여야 한다. Intravenous leiomyomatosis is a rare benign vascular tumor defined as the extension into venous channels of a histologically benign smooth muscle tumor arising either from a uterus or from the walls of uterine vessels, and about 10% spread to the heart. The treatment of choice is complete resection of the tumor. Hormonal therapy should be considered in cases of unresectable residual tumor. A 46-year-old woman was admitted for abdominal discomfort and pain. She was found to have intravenous leiomyomatosis of the uterus with extension into inferior vena cava and right atrium. The patient underwent surgery employing simultaneous sternotomy and laparotomy. Radical excision was achieved using cardiopulmonary bypass. We herein describe a patient in whom complete removal of intravenous leiomyomatosis with cardiac extension was successfully performed.

Bacillus cereus KCTC 3674 produced at least two kinds of extracellular proteases. Two major bands of the protease activity with molecular weights of approximately 100 and 38 kDa were obtained after gelatin-SDS-PAGE. The production of extracellular proteases occurred during the logarithmic growth phase and was greatest when cultures reached the stationary growth phase. On the other hand, the growth of B. cereus KCTC 3674 and the production of its extracellular proteases were severely inhibited by the addition of protonophore carbonylcyanide m-chlorophenylhydrazone (CCCP). Thus, it was concluded that the growth of B. cereus KCTC 3674 and the production of its extracellular pretenses were strongly affected by a H+ electrochemical potential.

The purpose of this study was to investigate the effects of the water extract of Mori Radicis Cortex(MRC) on blood glucose level and glutamic oxaloacetic transaminase(GOT), glutamic pyruvic transaminase(GPT), alkaline phosphatase(ALP) and lactate dehydrogenage(LDH) activities in streptozotocin(STZ) induced diabetic rats. Four groups of male Sprague-Dawley were a control group, STZ-diabetic group, Mori Radicis Cortex group and Mori Radicis Cortex + DTZ group. There was a significant decrease of glucose level elevated in diabetic rats treated with STZ, as compared with control group. The water extract of Mori Radicis Cortex recovered significantly above enzyme activities damaged by streptozotocin treatment. These results suggested that the water extract of Mori Radicis Cortex may be a potential antiglycemic and liver protective agents.

Kim, Woong Ji,Kim, So Ri,Choe, Yeong Hun,Lee, Ka Young,Park, Seoung Ju,Lee, Heung Bum,Chung, Myoung Ja,Jin, Gong Yong,Lee, Yong Chul The Korean Academy of Medical Sciences 2008 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.23 No.6

<P>Clear cell tumor of the lung is a rare and very unusual benign pulmonary tumor. As clear cell tumor of the lung contains abundant cytoplasmic glycogen, this tumor is called 'sugar tumor'. We report a case of sugar tumor in a 64-yr-old man presenting as a round pulmonary nodule. On dynamic computed tomography (CT) scans, the solitary pulmonary nodule showed early wash-in enhancement with an early washout pattern like a lung malignancy. The patient underwent wedge resection for the tumor. Pathologic examination, including immunohistochemical studies, revealed that the nodule was a benign clear cell tumor, so-called 'sugar tumor'. Because only a small number of cases have been reported previously, clinical aspects, radiological characteristics on dynamic contrast-enhanced CT, and differential diagnosis of the tumor are not well established. Herein we present a clear cell tumor of the lung and discuss the clinical, radiological, and pathological features of the tumor.</P>

Standard reference materials(SRM) have been used to certify the degree of accuracy for determining various kinds of analytes including environmental organic contaminants. In this study, we collected sediments from the Nakdong River estuary and Ulsan Bay. The levels of polychlorinated biphenyls(PCBs) and organochlorine pesticides were determined to investigate the availability of SRM and its homogeneity. The 8 congeners of PCBs and chlordane, p,p'-dichlorodiphenyldichloroethane(DDD), p,p'-dichlorodiphenyldichloroethylene(DDE), p,p'-dichlorodiphenyltrichloroethane(DDT), dieldrin, hexachlorobenzene(HCB) and oxychlordane were determined by using a capillary column gas chromatography/electron capture detector system. The environmental levels of these species md their relative standard deviations are discussed.
