Morphine은 강력한 진통작용으로 약효를 나타내고 있고 이와 같은 진통작용은 대체로 크게 대별하여 두 가지 기전으로 설명이 된다. 그 첫째는 수의 opioid수용체에 작용하여 척수에서 상행으로 전달되는 통각정보를 차단하는 것이며 또 다른 하나는 뇌에 존재하는 opioid수용체에 작용하여 진통작용을 발현한다고 알려져 있다. 실지로 임상에서 morphine을 실내에 주입하여 강한 진통작용을 가진바가 많이 보고되었다. 그러나, 아직 마약성 진통제가 뇌를 통하여 진통작용을 가지는 그 기전에 대해선 잘 밝혀지지 않았다. 많은 연구가 마약성 진통제가 뇌에 주입되면 뇌에 존재하는 opioid수용체에 작용하고 이 수용체를 가진 신경세포가 하향성 억제를 함으로써 척수에서 통각정보를 차단하여 진통작용을 나타냄을 시사한다. 그러나 아직도 이의 정확한 기전이 명쾌히 밝혀지지 않고 있다. 즉, 뇌실내에 morphine을 주입하면 이것이 과연 척수세포를 억제할 것인가에 대한 답이 없기 때문이다. 그와는 반대로 뇌실내 morphine주입은 척수세포에 아무런 영향을 미치지 못한다는 보고가 있다. 이에 본 실험은 뇌실에 주입된 morphine이 척수세포를 어떤 영향을 미치는가를 확인하고자 하였다.

Purpose: The purpose of this study was to identify the effects of abdominal breathing on state anxiety, stress and tocolytic dosage for pregnant women in preterm labor. Methods: The participants were 60 pregnant women in preterm labor who were hospitalized from April to July, 2009. Thirty participants were assigned to the experimental group and 30 to the control group. None of them had any other complications except preterm labor. The modified Mason's breathing technique was used with the experimental group 3 times a day for 3 days. Data were collected using a self-report questionnaire and chart review, and analyzed with the SPSS 13.0 WIN program. Results: "State anxiety of the experimental group will be lower than that of the control group" was supported. "Stress of the experimental group will be lower than that of the control group" was supported. "The Ritodrine dosage for the experimental group will be lower than that of the control group" was supported. "The Atosiban dosage for the experimental group will be lower than that of the control group" was supported. Conclusion: These results indicate that abdominal breathing is an effective nursing intervention for pregnant women in preterm labor.

본 연구에서는 904nm의 다이오드 레이저를 발치창에 조사하여 효과를 분석하교, 동물실험에서 제시된 가설 즉 레이저 광조사가 주위정상조직을 자극하여 창상치유를 촉진하고 진통, 항염증효과가 있는지를 확인하고저 하였다. 먼저 19명의 발치환자에게 발치후 즉시 1분간 평균 14mW의 저수준레이저를 조사하였다. 이들중 8명은 대조군으로서 위조사(sham-irradiation)하였다. 일주일동안 시간경과에 따른 동통의 정도, 진통제의 사용횟수, 진통제 사용기간등을 각각조사하였다. Visual analogue scale로 두근에서 동통의 정도를 비교한 결과 대조군 보다 레이저 조사군에서 동통이 유의하게 감소하였으며, 진통제의 사용횟수가 기간도 레이저조사군에서 유의하게 감소하였다. 이러한 결과로 보아 비록 1분간의 적은 량의 레이저 조사라도 발치후 합병증을 억제하여 동통을 억제하고 치유를 촉진한다고 사료된다.

The management of post-thoracotomy pain is on of the difficult clinical problems. A variety of pain management methods have been used with variable efficacy. We compared the effect of acupuncture with the effect of analgesics for the post-thoracotomy pain control. From March 1995 to September 1995, 20 patients who underwent elective thoracotomy were randomized into two groups. The patients were treated with analgesics in control group(n=10) and acupuncture in the other group(n: 10). Postoperative analgesic effects were evaluated by the scoring system which was made by the Department of Thoracic and Cardiovascular Surgery, Korea University Medical Center. No significant difference was observed between two groups concerning the subjective pain and limitation of motion of operated side. Although the number of analgesic requirement was reduced significantly in the acupuncture group(P < 0.05). We conclude that acupuncture is an effective method to control post-thoracotomy pain and it is safer than the analgesics bacause of its lower side effects.

흰쥐의 뒷발바닥에 carragennan(cg)을 피하투여하여 염증성 통증을 유발한 뒤, 그 통증이 최고에 달하는 3시간 뒤 Ach이나 SNP를 동일한 항법으로 투여해서 30분 후 cg유발 통증에 대하여 그 효과를 Randall-Selitto paw pressure test로 검색하였고, 체내 Nitric Oxide Synthase(NOS) 억제제인 L-NAME과 L-NOARG를 용량별로 적용하여 Ach의 진통효과를 억제하는 정도와 Methylene Blue 및 Hemoglobin을 투여해서 SUP효과 억제를 검사하였다. 그리고 척수 지주막하강내로 catheter를 삽입하여 위의 NO donor를 주입하고, NO의 중추신경계에서의 통각전도에 미치는 효과를 Tail-Flick test로 살펴보았다. 끝으로 NO가 가진 급,만성 통각관련효과를 희석한 formalin을 써서 검색하였다. 결 과: Ach과 SNP는 흰쥐에게 말초경로투여시 유의성있는 진통효과를 보였으며, NOS inhibitor와 NO scavenger로 그 효과가 역전되었다. 또한 NOS inhibitor간에는 억제효과가 용량의존성이 유사하게 나타났고, 중추신경계로의 직접투여때는 여러 생리적 조건이 직, 간접으로 관여함이 확인되었다.

Effects of Allolobophora caliginosatrapezoides (Ac) polysaccharide fractions on the inflammation and hypersensitivity were studied in vivo. It showed that Ac polysaccharide fractions have the significant inhibitory activities of inflammation and hypersensitivity; They inhibited significantly the carrageenin-induced paw edema and acetic acid-induced writhing syndrome. They also inhibited significantly the Arthus reaction and delayed hypersensitivity in the sheep red blood cell-sensitized mice in accordance with the inhibition of haemaglutinin titer, haemolysin titer, plaque-forming cells and rosette-forming cells. They also improved markedly the oxazolone-induced dermatitis in rats dose-dependently. As the above results, it exhibited that Ac polysaccharide fraction inhibited not only humoral immune response, but also cell-mediated immune response. It seemed that methanol and ether extracts have also another physiological active agents.

Root of Asarum sieboldii has been used in chinese medicine. It was been known that the extract of A. sieboldii has medicinal effect such as antifebrile, anodyne, and anti-inflammatory. Antifungal activity of the essential oil extracted from A. sieboldii against various epiderman and opportunistic human pathogenic fungi was investigated. Steam-distillated essential oil demonstrated very high antifungal activity against Aspergillus fumigatus, Aspergillus niger, Cryptococcus neoformans, and Candida albicans. MIC (minimum inhibitory concentration) of the essential oil against C. albicans was 5 ul/ml, indicating that the essential oil may be used as natural preserves for cosmetic and nutritional products.

Buprenorphine, one of the mixed agonist-antagonist opioid drugs was used to inverstigate the opioid receptor on frog sciatic nerve A fibers. Action potentials were recorded for 4 hrs by a sucrose gap apparatus which were separated by four rubber membranes. To examine the one of the mechanism of action of buprenorphine, meperidine or naloxone was added after or before the treatment of buprenorphine. The results of this experiment were as follows: 1. Buprenorphine suppressed significantly the compound action potentials of frog sciatic nerve, and the maximal effects were shown both at $10^{-4}\;M$ and at $10^{-8}\;M$. 2. The dose-response relationship of buprenorphine on the depressant effect in frog sciatic nerve was biphasic and inverted U-shaped. 3. Buprenorphine blocked the effect of Meperidine $(10^{-3}\;M)$ on this preparation. 4. The depressant effcct of Buprenorphine on frog sciatic nerve was blocked by $10^{-8}\;M$ naloxone. From the above results, buprenorphine acts as one of agoinist-antagonistic effect on frog sciatic nerve, and the opioid receptor on this preparation is located on or near the intracellular opening of the sodium channels, which are sensitive to naloxone.

문헌에 의하면 대상포진의 원인은 바이러스에 대한 세포성 면역이 저하될 때, 또는 악성종양 등으로 면역억제제 치료를 받아서 2차적으로 면역이 저하될 때 체내에 잠재해 있던 바이러스가 재활되어 발병하는 것으로 추정하고 있다. 본 저자도 이에 대하여 의견을 같이하고 있는데 노령층의 $60\~70$대 여자환자수가 압도적으로 많았다는 점과, $20\~39$세 사이의 청${\cdot}$장년층에서는 단1명의 대상자가 없다는 점뿐 아니라, 본 대상자중 11세의 소녀는 7세때 뇌종양 수술을 2차례에 걸쳐 실시한 후 면역제제를 계속적으로 사용하는 있는 점 등은 문헌의 발병원인과 상당히 일치하였다. <전파 양식> 비말 감염 (droplet infection)으로 전파되며, 수두와 달리 전염성이 높지 않다. <잠복기> 잠복해 있던 바이러스가 언제 재활할지 알 수 없으므로 불명이다. 그러나 본조사에서는 대상포진에 대한 병력을 가진 사람이 없었고, 발생 원인을 본인 자신도 모르고 있었다. <합병증> Ramsay Hunt의 증후에 의하면 합병증은 외이도의 수포, 안면신경마비, 혀의 2/3부분의 미각상실, 간혹 청각 및 평행장애를 일으킨다고 한다. <치료> 대상포진의 대증요법으로 calamine lotion Burrow solution의 wet dressing 진통제 및 cytosine arabinoside나 adenosine arabinoside와 같은 항히스타인제, 최근에는 Acyclovir가 많이 사용되고 있는 것으로 알려졌다.

The study was conducted to confirm the analgesic effects of the Carbenoxolone(CBX)and P2X receptor antagonist(iso-PPADS), which separates the gap junction in the facial neuropathic pain model. The experiment used white male Sprague-Dawley rats (240~280g). The second left molars on the lower jaw was extracted to induce facial neuropathic pain, and small dental implants were implanted to induce damage to the inferior alveolar nerve. When CBX was injected twice daily to the abdominal cavity, a significant analgesic effect at 5ug/kg was observed(p<0.05). In addition, when iso-PPADS was injected twice daily into the abdominal cavity, a significant analgesic reaction was observed at $25{\mu}g/kg$(p<0.05). When the two drugs were injected together at a low concentration, in which they did not display an effect, they displayed a significant analgesic reaction at CBX 1ug/kg and iso-PPADS 2.5ug/kg(p<0.05). When a gap injunction block using a low concentration of CBX and a low concentration P2X receptor antagonist was injected together, the pain suppressing effect was observed against the orofacial neuropathic pain mechanism. These results make it possible to determine that the gap junction block using CBX and the injection of the P2X receptor antagonist plays an important role in the pain management of the facial region.
