The aim of our study is to investigate the anti-nociceptive and anti-inflammatory properties of an ethanol extract of the leaf and stem of Aralia cordata. Writhing responses induced by acetic acid, tail immersion test, and formalin-induced paw pain response for nociception and formalin-induced paw edema for inflammation were evaluated in mice. A. cordata (50 - 200 mg/kg, p.o.) and ibuprofen (100 mg/kg, p.o.), a positive non-steroidal anti-inflammatory drugs (NSAIDs), inhibited the acetic acid-induced writhing response, but they did not protect the thermal nociception in tail immersion test. However, morphine (5 mg/kg, s.c.) used as positive opioid control alleviated both the acetic acid-induced writhing response and thermal nociception in tail immersion test. In the formalin test, A. cordata (50 - 200mg/kg) and ibuprofen (200mg/kg) inhibited the second phase response (peripheral inflammatory response), but not the first phase response (central response), whereas morphine inhibited both phase pain responses. Both A. cordata (100 mg/kg) and ibuprofen (200 mg/kg) significantly alleviated the formalin-induced increase of paw thickness, the index of inflammation. These results show for the first time that the leaf and stem of A. cordata has a significant anti-nociceptive effect that seems to be peripheral, but not central. A. cordata also displays an anti-inflammatory activity in an acute inflammation model. The present study supports a possible use of the leaf and stem of A. cordata to treat pain and inflammation.

Purpose: Pain management in burn treatment is important in improving wound healing and quality of life. Ibuprofen is a proven pain relieving agent in patients with partial thickness burn by intraveous injection. The purpose of this study is to evaluate the efficacy of Biatain Ibu^® (polyurethane foam containing ibuprofen) in pain control for outpatients with partial thickness burns. Methods: A prospective randomized clinical trial was performed in outpatients with partial thickness burn from August 1, 2017 to July 31, 2018. Acute pain, chronic pain, complications, days for re-epithelialization and patient's satisfaction were compared between Biatain Ibu^® and Biatain^® groups. Results: A total of 20 patients (Biatain Ibu^®, n=10; Biatain^®, n=10) were assessed in the trial. On Burn days 3, 5, 7, 11, 13, and 15, the acute pain levels were significantly lower in the Biatain Ibu^® group than in the Biatain^® group. Complications, chronic pain levels and days for re-epithelialization were not significantly different between the two groups. Patient's satisfaction was not statistically significant but was higher in the Biatain Ibu^® group. Conclusion: Biatain Ibu^® is effective in relieving pain in outpatients with partial thickness burn without decreasing patient satisfaction, wound healing ability or developing any complications.

MAPKs는 다양한 세포자극에 반응하는 중요한 세포신호전달경로이며, 특히 세포의 생존과 사멸과정에 관여한다고 알려져 있다. 그러나 위궤양의 진행에 있어 MAPKs의 세포특이적 활성에 관한 연구결과들에 대해서는 잘 알려져 있지 않다. 본 연구에서는 이부프로펜에 의해 유도된 위궤양의 진행에 있어 활성화된 MAPKs가 다양한 세포들에 어떻게 분포하는지를 실험하였다. 위궤양 유발은 200 mg/kg 이부프로펜을 하루에 8시간간격으로 3번 투여하였다. 동물부검은 이부프로펜을 투여한 후 24, 48, 72시간에 실시하였고, 위조직은 면역조직화학 및 웨스턴블랏에 사용되었다. 활성화된 p-ERK는 정상 랫드 위점막상피의 위상피증식층에서만 주로 발현되었으나, 이부프로펜을 투여한 후 24시간째에는 위기저부의 벽세포들에서 강하게 발현되었다. 이부프로펜을 투여 후 48시간 경과한 군에 있어서는 위궤양에 인접한 위점막상피 또는 위궤양 기저부의 결합조직에 나타난 신생혈관, 염증세포 및 육아조직에서 p-ERK가 강하게 발현되었다. 반면에 p-JNK는 초기 위점막손상을 나타내는 위표면점막상피와 샘위의 점막상피세포의 핵에서 주로 발현되었다. 점차적으로 p-JNK는 위궤양 기저부의 결합조직내에 침윤된 염증세포, 섬유모세포에서 특히 강하게 염색되었다. P-p38 양성세포는 위점막의 결합조직내에서 분산되어 관찰되었으며, 특히 위궤양 기저부의 결합조직내로 침윤된 대식 세포에 강한 염색성을 나타내었다. 이상의 연구결과는 각각의 MAPK들이 위궤양진행에 있어 특정세포들의 활성화에 관여하는 것으로 보여진다.

비 스테로이드성 항염증제에 대한 개별적 독성증상을 예방하기 위해 로박스 플라티넘(Robax Platinum), 로박스아세트(Robaxacet), 나프록센(Naproxen) 그리고 재활치료를 선택적으로 처방하여 비 스테로이드 진통소염제(Non-Steroidal Anti-Inflammatory Drugs)에 대한 독성증상을 예방을 위한 효과 비교 연구를 진행하였다. 이 연구에서는 로박스 플라티넘(Robax platinum), 로박스아세트(Robaxacet), 나프록센(Naproxen)을 주한미군 처방전(Annex A-Over-The-Counter Prescription)을 기준으로 하여 처방하였고, 앨리스 리치의 통증 척도(Alice Rich's Pain Scale)를 사용하여 통증 경과를 비교하고 그 결과를 IBM SPSS statics 24 버전을 사용하여 데이를 계산했다. 결합된 메토카바몰(Methocarbamol, 500 mg), 아세트아미노펜(Acetaminophen, 325 mg), 이부프로펜(Ibuprofen, 200 mg) 정제는 결합된 메토카바몰(Methocarbamol, 500 mg) 정제와 함께 사용할 수 있다. 아세트아미노펜 (Acetaminophen, 325 mg)의 알약이 통증을 조절하는 방법으로 사용되었다. 메도카바몰 500mg, 아세트아미토펜 325 mg 및 이부프로펜 200 mg 정제의 약물 조합은 메도카바몰 500 mg 및 아세트아미노펜 325 mg 정제가 전반적인 통증 조절과 관련하여 물리적인 스트레칭 운동과 쌍을 이룬 것과 유사한 통증 완화효과를 나타내었다.

Ibuprofen (IBU), is a non-steroidal anti-inflammatory drug, used to treat rheumatoid arthritis, removal of fever and mild to moderate pain. Because of small dosage and very low accumulation in the body, IBU has been used to heal children's fever. However, IBU was very low solubility in a low pH and water (in water $0.03{\sim}2.5$ mg/ml). A nanoemulsion containing IBU by means of self-microemulsion drug delver system (SMEDDS) was prepared in order to enhance the solubility of IBU. The SMEDDS was composed of cosurfactant, oil and surfactant The solubility of IBU in various components such as cosurfactant, oil and surfactant was examined. $Carbitol^{\circledR}\;(386.99{\pm}20.5\;mg/ml)$ as a cosurfactant, $Labrafil^{\circledR}$　 M1944CS $(90.16{\pm}1.60mg/ml)$ as an oil and $Cremopher^{\circledR}$　 RH-40 $(239.01{\pm}2.8\;mg/ml)$ as a surfactant were used in this study for preparing SMEDDS. Optimized formulation of SMEDDS was obtained by phase diagram which express the section of nanoemulsion formation. The SMEDDS containing IBU had higher dissolution rate than conventional IBU sirups. Thus the SMEDDS was a potential candidate of stable conventional and effective oral dosage form for IBU.

Three 1,2-benzothiazine derivatives were synthesized, and their analgesic / anti-inflammatory efficacy and their effect s of gastric irritation were evaluated. Among the three compounds, 39 exhibited the most potent anlagesic action, but the effect was weaker than that of piroxicam. Nonetheless, the compound showed 4 times more potent analgesic action with less gastric damage than did ibuprofen. These compounds did not show anti-inflammatory effect at an oral dose of 5 mg/kg.

In this study, ibuprofen(IBP) degradation by the photochemical ($UV/S_2O{_8}^{2-}$) and sonochemical ($US/S_2O{_8}^{2-}$) processes was examined under various parameters, such as UV ($10{\sim}40{\pm}5W/L$) and US ($50{\sim}90{\pm}5W/L$) power density, optimum dosage of persulfate ion ($S_2O{_8}^{2-}$), temperature ($20{\sim}60^{\circ}C$) and anions effect ($Cl^-$, $HCO_3{^-}$, $CO{_3}^{2-}$). The pseudo-first-order degradation rate constants were in the order of $10^{-1}$ to $10^{-5}min^{-1}$ depending on each processes. The synergistic effect of IBP degradation in $UV/S_2O{_8}^{2-}$ and $US/S_2O{_8}^{2-}$ processes could investigated, due to the generation of $SO_4{^-}$ radical. This result can confirm from the produced $H_2O_2$ and $SO{_4}^{2-}$ concentration in each processes. IBP degradation rate affected by the $S_2O{_8}^{2-}$ dosage, temperature, power and anion existence parameters. In particular, IBP degradation rate increased with the increase of the temperature ($60^{\circ}C$) and applied power density (UV:$40{\pm}5W/L$, US:$90{\pm}5W/L$). On the other hand, anions effect on the IBP degradation was negative, due to the anion play as a the scavenger of radical.

Because of the differences in biological and pharmacological properties between enantiomers of chiral acidic non-steroidal antiinflammatory drugs (NSAIDs) in human body. accurate determinations of their optical purities have been in great need. Racemic ibuprofen. tiaprofen. suprofen. flubiprofen and napoxen were reacted with (1R. 28. 5R)-(－)-menthol to convert them to corresponding diastereomeric (1R. 2S. 5R)-(－ )-menthyl esters. (omitted)
