Research was undertaken to compare the pharmacological activity of Lithospermi radix (LR) reported as an oriental medicine for classical uses. LR contains naphthoquinone pigments : shikonin, acetylshikonin, isobutylshikonin, etc. LR is used for the treatment of excision wound, burn, eczema, blister, scarlatina and septicemia as antifebrile, antidotic and antiphlogistic. Gardeniae fructus (GF) has been used for the treatment to jaundice, hepatic disease, anti-inflammatory and analgesic effects, and it contains crocin, geniposide and its derivatives. The therapeutic effects of burn and excision wound healing from LR & GF hydrogel with $Nano-ATP^{\circledR}$ (GLN) were investigated. To evaluate the therapeutic value of various hydrogels, thermal burn model and excision wound mouse model were used. The burn and wound reduction rate and therapeutic period were measured to calculate the healing extent after 5 experiments. The 2nd degree burn was prepared on hairless mouse back skin and dressing with collagen. The burn and wound reduction rate of GLN hydrogel treated group decreased more rapidly than that of other gel group in animal model. Furthermore therapeutic periods of GLN hydrogel treated group was shorter than that of other gel group. In anti-inflammatory test, GLN hydrogel treated group decreased edema rapidly than that of other gel group. These results suggest that the GLN hydrogel treatment has an therapeutic effect on burn and excision wound healing.

Dipsaci Radix (Dipsacaceae) has been used as a tonic, an analgesic, anti-inflammatory and anti-complement agents in traditional herbal medicine for the therapy of low back pain, knee pain, rheumatic arthritis, traumatic hematoma, and bone fractures. A high-performance liquid chromatography-electrospray ionization-mass spectrometric method (HPLC-ESI-MS) was developed for the simultaneous quantitation method of the five compounds from the herbal drug: asperosaponin VI and asperosaponin XII (terpene glycosides), sweroside, loganin and dipsacus A(iridoid glycosides). HPLC separation of the analytes was achieved on a C18 column ($150{\times}2.0$ mm i.d., 5 ${\mu}m$) using the aqueous methanol containing 5 mM ammonium acetate with gradient flow of the mobile phase. Detection of the analytes was performed by positive ion electrospray ionization, and selected ion monitoring was used for data acquisition using m/z corresponding molecular adduct ion, $[M+NH_4]^+$ and $[M+H]^+$. Calibration graphs showed good linearity ($r^2$=0.9997) over the wide range of the analytes; intra- and inter-day precisions (RSD, %) were within 9.1% and the accuracy between 94.0-111.0%. Recoveries of the analytes through the assay procedure were in the range of 93.7-110.8%. Analytical results of the herbal drugs of Dipsaci Radix (17 samples) show wide distribution of the five marker compounds and clear difference of the species from Phlomidis Radix (4 samples). The developed method would provide a practical guide for the quality control of the herbal drug.

Background: Studies on the pain have been dealing with many different ways for last several centuries. Especially, preemptive analgesia is being used as a method to control the postoperative pain. Many studies on its efficacy have been processed in different ways about various drugs, administration methods and times for various operations. And the value of preemptive analgesia are still controversial regarding the results of other clinical studies. The authors performed a clinical study on efficacy of preemptive analgesia using an non-steroidal anti-inflammatory drug (NSAID) for the surgical extraction of impacted third molar teeth and present the more effective pain treatment after oral surgery with literature review. Methods: Using a randomized double blind test design, this study compared the analgesic efficacies of an NSAID, Talniflumate 370 mg. This drug administrated first either 1 hour preoperatively (experimental group) or when the pain developed moderately to severely over 5 scale of verbal rating scales (0-10) to respective 30 patients undergoing the removal of impacted third molars. Pain intensity and the time from the end of surgery were assessed postoperatively whenever the patients demanded additional drug over 5 scale for forty eight hours using same verbal rating scales. Results: The sex distribution, the age of the patients. and the time required for surgery in two groups were similar. The average first time for demanding additional drug after surgery was 163.9 minutes in experimental group and 191.5 minutes in control group. At this time, the average pain intensity was 5.8 in experimental group and 6.1 in control group. And the average second time for demanding additional drug was 365.5 minutes in experimental group and 351.8 minutes in control group. At this time. the average pain intensities were 6.6 in experimental group and 6.2 in control group. No statistically significant difference was found between the average first times and second times, and the average pain intensities at first and second times in two groups. Conclusions: From these results the efficacy of preemptive analgesia used in this study was not appeared. This clinical study indicates that many NSAIDs administrated preoperatively in present practices have weak efficacy of preemptive analgesia for postoperative pain, thus the authors recommend that only postoperative analgesics are adequate without preoperative use of analgesics.

Casticin (3', 5-dihydroxy-3, 4', 6, 7-tetramethoxyflavone) is an active compound isolated from roots, stems, leaves, fruits and seeds of a variety of plants. It is well known for its pharmacological properties and has been utilized as an anti-hyperprolactinemia, anti-tumor, anti-inflammatory, neuroprotetective, analgesic and immunomodulatory agent. Recently, the anticancer activity of casticin has been extensively investigated. The resulkts showed that it exerts protective potential by targeting apoptosis, considered important for cancer therapies. In this article, our aim was to review the pharmacological and therapeutic applications of casticin with specific emphasis on its anticancer functions and related molecular mechanisms. Chemotherapeutic effects are dependent on multiple molecular pathways, which may provide a new perspective of casticin as a candidate anti-neoplastic drug. This review suggests that additional studies and preclinical trials are required to determine specific intracellular sites of action and derivative targets in order to fully understand the mechanisms of its antitumor activity and validate this compound as a medicinal agent for the prevention and treatment of various cancers.

Background: Third molar extraction is associated with considerable pain and discomfort, which is mostly managed with oral analgesic medication. We assessed the analgesic effect of benzydamine hydrochloride, a topical analgesic oral rinse, for controlling postoperative pain following third molar extraction. Methods: A randomized controlled trial was conducted in 40 patients divided into two groups, for extraction of fully erupted third molar. Groups A received benzydamine hydrochloride mouthwash and group B received normal saline gargle with oral ibuprofen and paracetamol. Oral ibuprofen and paracetamol was the rescue analgesic drug in group A. Patients were evaluated on the $3^{rd}$ and $7^{th}$ post-operative days (POD) for pain using the visual analogue score (VAS), trismus, total number of analgesics consumed, and satisfaction level of patients. Results: The VAS in groups A and B on POD3 and POD7 was $4.55{\pm}2.54$ and $3.95{\pm}1.8$, and $1.2{\pm}1.64$ and $0.95{\pm}1.14$, respectively and was statistically insignificant. The number of analgesics consumed in groups A and B on POD3 ($5.25{\pm}2.22$ and $6.05{\pm}2.43$) was not statistically different from that consumed on POD7 ($9.15{\pm}5.93$ and $10.65{\pm}6.46$). The p values for trismus on POD3 and POD7 were 0.609 and 0.490, respectively and those for patient satisfaction level on POD3 and POD7 were 0.283 and 0.217, respectively. Conclusions: Benzydamine hydrochloride oral rinses do not significantly reduce intake of oral analgesics and are inadequate for pain relief following mandibular third molar extraction.

Aspirin or acetylsalicylic acid, a member of the salicylate family, is frequently used as an analgesic, antipyretic, anti-inflammatory and antiplatelet drug. Because aspirin is chemically unstable in water and heat for tablet formulation, additives including lubricants are used in preparing aspirin tablets, using a dry-granulation process. Aspirin tablets are produced by a number of manufacturers which usually use their own unique combination of additives during the manufacturing process. In this study, we employed an NMR based metabolomics technique to identify the manufacturers of various aspirin tablets. Aspirin tablets from six different companies were analyzed by 1H 400 MHz NMR. The acquired data was then integrated and processed by principal component analysis (PCA). Based on the NMR data, we were able to identify peaks corresponding to acetylsalicylic acid in all of the six samples, whereas different NMR patterns were found in the aromatic and aliphatic regions depending on the unique additive used. These observations led to the conclusion that the differences in the NMR patterns among the different aspirin tablets were due to the presence of additives.

Ibuprofen is one of the nonsteroidal anti-inflammatory drugs (NSAID) and has shown antiinflammatory; antipyretic, and analgesic activity in both animals and humans. But it causes gastric mucosal abnormalities including edema, erythema, and submucosal petechial hemorrhages and erosin in human. In addition, based on the pharmaceutical point of view the compression and dissolution ability of ibuprofen is known as poor. Therefore we studied to develop novel formulation containing water-insoluble drug, ibuprofen, using microemulsion consisting of surfactant, oil phase, and water phase was prepared for the purpose of increasing its bioavilability The physicochemical properties such as particle size, dissolution rate, solubility of ibuprofen in the system were determined. After oral administration of ibuprofen containing the microemulsion system, to Sprague-Dawley rats, pharmacokinetic parameters were also obtained. For the formulation in the study, oleic acid, linoleic acid, and several kinds of glycerides and triglycerides were used as an oil phase with several surfactants. Diethylene glycol monoethyl ether (Transcuto $l^{ }$) or saturated polyglycolized glycerides (Labrafil $^{ }$)as surfactant was used, the domain of microemulsion was wide. The diameter of o/w microemulsion was ranged from 90 to 220 nm. Microemulsion, prepared with unsatulated polyglycolized glycerides (Labrafil $^{ }$) and the 2 : 1 molar mixture of diethylene glycol monoethyl ether (Transcuto $l^{ }$)/polyoxyethylene(4) lauryl ether (Bri $j^{ }$ 30) , is expected to be promising system that increased the bioavilability of ibuprofen.ibuprofen.

Background: Ketorolac($Tarasyn^{(R)}$) is a non-steroidal anti-inflammatory drug(NSAID) which has shown to be an effective postoperative analgesic available parenterally, and when combined with morphine can reduce its requirement. The analgesic efficacy and adverse effects of continuous infusion of ketorolac added to morphine IV PCA was evaluated in 60 women after abdominal hysterectomy. Methods: Patients were assigned to receive either morphine intravenous(IV) bolus followed by morphine IV patient controlled analgesia(PCA), or ketorolac 30mg IV and continuous IV infusion at 4.0mg/hr in combination with the above regimen. The authors evaluated PCA morphine used, pain assessment(verbal pain intensity score and visual analogue scale) and side effects at 2, 4, 6 and 24hrs during pain control. Results: Continuous infusion of ketorolac decreased the PCA morphine usage significantly(30.4 ---> 19.6 mg : p=0.007) at 24hrs postoperatively. Significant differences were seen favoring ketorolac infusion in pain intensity and visual analogue scale both at rest and during movement. There were no differences in incidences of deep sedation, nausea & vomiting. But the ketorolac group they complained of dizziness more than morphine only group. Little pruritus was recorded in either groups. Conclusions: The authors conclude continuous IV infusion of ketorolac in conjunction with morphine PCA provide effective analgesia after low abdominal surgery.

Ketorolac tromethamine(KT) is a nonsteroidal agent with potent analgesic and moderate anti-inflammatory activity. The lipid-water partition coefficient of KT was evaluated and KT gel was formulated as a gel containing different pH, different concentrations of polymer (poloxamer 407, carbopol 941), propylene glycol, ethanol and various enhancers. The resulting KT gels were evaluated with respect to their viscosity, in vitro drug permeation rate through hairless mouse skin and stability. In n-octanol and chloroform, the lipid-water partition coefficient of KT was the highest at pH 4 phosphate buffer. The apparent viscosity of KT gel increased with an increase in gel pH, polymer and enhancer concentration. But the apparent viscosity of KT gel decreased with an increase in ethanol concentration. The permeation rate of KT through hairless mouse skin from gels different pH was maximum at pH 4 which is close to KT $pK_{a}$ 3.54. The permeation rate decreased with an increase in polymer, propylene glycol concentration. But the permeation rate increased with an increase in ethanol. The increase of drug concentration from 1 to 3% induced linear increase in permeation rate. The best enhancer was the combination of $Labrasol^{\circledR},\;Transcutol^{\circledR}$, oleic acid and l-menthol. In the accelerated stability test(25, 40 and $50{\circ}C$), pH 5 gel was most stable and pH 4 gel was most unstable for 90 days.

Objectives : Angelicae Gigantis Radix (AG) is a plant of the Ranunculus family. AG have been reported to have various pharmacological effects on human health which include uterine growth promotion, anti-inflammatory, analgesic, and immune enhancement. However, research on dermatitis disease is insufficient. Therefore, we investigated the effects of AG on tumor necrosis factor-α (TNF-α)/interferon-γ (IFN-γ) stimulated HaCaT cell. Methods : To investigate the effect of AG on HaCaT cell, HaCaT cells were pre-treated with AG for 1 hour and then stimulated with TNF-α/IFN-γ. After 24 hours, media and cells were harvested to analyze the inflammatory mediators. Concentration of human interleukin-1beta (IL-1β), monocyte chemoattractant protein-1 (MCP-1), granulocyte-macrophage colony-stimulating factor (GM-CSF), and TNF-α in the media were assessed by ELISA. mRNA expression of human thymus and activation-regulated chemokine (TARC), IL-6, and IL-8 were analyzed by RT-PCR. Additionally, the mechanisms of mitogen-activated protein kinases (MAPKs) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling pathway were investigated by Western blot. Results : The treatment of AG inhibited gene expression levels of IL-6, IL-8, and TARC and protein expression levels of IL-1β, MCP-1, and GM-CSF. Also, AG significantly reduced extracellular signal-regulated kinase (ERK) phosphorylation and NF-κB translocation in TNF-α/IFN-γ stimulated HaCaT cell. Conclusions : Taken together, these results demonstrate that AG can alleviate inflammatory diseases such as atopic dermatitis by regulating the expression of inflammatory cytokines. Also, it suggest that AG may a promising candidate drug for the treatment of inflammatory disease such as atopic dermatitis.
