In this study, we investigated the potential of Resina Pini (RP) for anti-inflammatory and analgesic agents to treat inflammatory diseases such as gingivitis and periodontitis. Crude RP (RP1), recrystallized RP (RP2), and Ramus Mori Albae-treated RP (RP3), plus their respective water extracts (RP1-WE, RP2-WE and RP3-WE) were prepared for in vitro and in vivo tests. We couldn't find any signs of heavy metals pollution in all the RP samples. RP2-WE exhibited the highest viability of human gingival fibroblasts (HGF) and the strongest scavenging activity on superoxide anion. RP1, RP2 and RP3, RP2 showed potent scavenging activity on DPPH free radical. RP2-WE displayed a stronger inhibition on hyaluronidase (HAase) activity and RP3 also displayed potent HAase inhibition. RP2-WE, RP3-WE, RP3 and RP2 were reduced admirably the production of $PGE_2$ in HGF. In addition, RP2-WE and RP3-WE exhibited potent inhibitory activities on arachidonic acid-induced ear edema in mouse. Moreover, RP-2 prevented completely acetic acid-induced writhing by 100.0% and RP1, RP3, RP1-WE and RP2-WE also exhibited excellent protective activities against writhing. While aminopyrine, the positive control, showed 76.9% analgesic effect at the same dose. Taken together, these results suggest that recrystallized aqueous extract of Resina Pini could be a promising drug for the treatment of periodontal diseases.

Backgrounds : Scutellaria baicalensis has been used as a medicinal plant to treat various disease conditions accompanying inflammatory response and oxidative stress. Objectives : The aim of this study is to evaluate the effects of Scutellaria baicalensis against inflammatory, pain and edema Methods : In vitro, the effects of Scutellaria baicalensis against lipopolysaccharide-induced inflammation were investigated in mouse BV2 microglial cells. In vivo, the effects of Scutellaria baicalensis on acetic acid-induced writhing response, carrageenan-induced edema and the plantar test (nociceptive thermal stimulation) were investigated using rats and mice. Results : The present results showed that pre-treatment with the aqueous extract of Scutellaria baicalensis suppressed the lipopolysaccharide-stimulated cyclooxygenase-2 expressions in mouse BV2 microglial cells. The aqueous extract of Scutellaria baicalensis inhibited acetic acid-induced abdominal pain in mice and also reduced thermal pain in rats. However, no significant inhibition on carrageenan-induced edema in rats. Conclusions : The present study showed that Scutellaria baicalensis possesses anti-inflammatory and analgesic effects.

Polygoni multiflori Ramulus, the stem of Polygonum multiflorum Thunb., has been widely used as a traditional medicine for the treatment of many diseases. Presently, antinociceptive tests of the butanolic fraction of P. multiflorum (SPB) were performed using several thermal and chemical pain models. SPB had strong and dosedependent antinociceptive activities, both thermal and chemical, compared to the reference drugs Tramadol and Indomethacin. In combination with naloxone, the analgesic activity of SPB was unchanged indicating that the antinociceptive activity of SPB was not due to action as an opioid receptor agonist. The present results indicate the potential of SPB as an analgesic agent for pain control.

The comparative studies were made on the analgesic antipyretic effects of aminopyrine used individually and combined with parasympathetic agents (atropine sulfate). The analgesic antipyretic effects were eximined by Writhing's method to the experimental groups(mouse), and the following effects were found : 1) The active intensity of aminopyrine by it's oral administration combined with atropine sulfate is as follows. Amiinopyrine 80 mg/kg combided with Atropine sulfate 0.005 mg/kg=Aminopyrine 100 mg/kg 2) The most active range of intensity of Atropine sulfate(adjuvant) by it's oral administration is as follows. Atropine sulfate $0.004{\sim}0.005\;mg/kg$.

Poria cocos is a natural substance known to have anticancer, antioxidant and anti-inflammatory effects. The aim of this study is to investigate the analgesic effects of Poria cocos extract (PCE). We evaluated the analgesic effects of PCE using adjuvant induced arthritis rat model. Male SD rats were administered intra-orally with PCE according to prescribed dosage, during 6 days. After 6 days later, serum TNF-α, IL-1β, and IL-6 levels were measured by ELISA. In our experiment, administration of PCE decreased TNF-α, IL-1β, IL-6 and PGE2 level in serum. Furthermore, it was confirmed that allodynia was relieved in evaluation of pain behavior. It was confirmed that administration of PCE reduces nociceptive pain by reducing nociceptive stimuli by acting as an anti-inflammatory drug.

The aim of this study is to investigate the analgesic effects of Syneilesis aconitifolia Maxim. extract (SAM). We evaluated analgesic effects of SAM on animal pain model. Male SD rats were administered intra-orally with SAM according to prescribed dosage. During 7 days. After 7 days later, serum TNF-α, IL-1β, and IL-6 levels were measured by ELISA. In our experiment, administration of SAM decreased IL-1β, IL-6, TNF-α and PGE2 level in serum. Furthermore, it was confirmed that allodynia was relieved in evaluation of pain behavior. It was confirmed that administration of SAM reduces nociceptive pain by reducing nociceptive stimuli by acting as an anti-inflammatory drug.

This study was conducted to investigate the effect of an anti-inflammatory and analgesic action of the glucosamine HCl (Glucosamine) and SH-1 (Glucosamine + Oriental herbal composition combined group). Male sprague-Dawley rats $(200{\sim}250g)$ and ICR mice $(20{\sim}30g)$ were randomized and these experimental groups were divided into 4 groups. Two control group were given as negative control (saline) and positive control (Ibuprofen, 100 mg/kg) and two groups given as oral administration of Glucosamine (320 m/kg) and SH-1. Carrageenan induced paw edema test, hot plate method, croton oil induced granuloma, capillary permeability test and acetic acid writhing syndrome were also shown to be comparable in the SH-1 group to anti-inflammatory drug group such as positive control group (Ibuprofen). Although further studies should be performed to confirm the effects of SH-1, present results suggest that the combined administration of SH-1 have potential action in anti-inflammatory and analgesic action. It could be applicable for the improvement of arthritic symptoms as a new diet-supplement.

This study examined the antinociceptive properties of GCSB-5, a herbal formulation consisting of 6 Oriental herbs (Ledebouriellae Radix, Achyranthis Radix, Acanthopanacis Cortex, Cibotii Rhizoma, Glycine Semen, and Eucommiae Cortex) that are used in traditional medicine to treat various bone disorders, mainly of which involve analgesic processes. Peripheral and central analgesic models were established in experimental animals in order to evaluate the antinociceptive effects of the agent. GCSB-5 significantly inhibited the number of acetic-induced writhing (33.3%-34.3% inhibition at 100-600 mg/kg) but increased the pain threshold (38.0% increase at 300 mg/kg) in the Randall-Selitto test. However, GCSB-5 had no effect on the hot plate-induced nociception and hyperalgesia from the tail-pinch method. These results suggest that the antinociceptive effect of GCSB-5 may be mediated via peripheral mechanisms.

Objectives : The present study was undertaken to determine whether the ethanol extact of Citri Pericarpium (CP, Pericarp of Citrus unshiu Markovich, Rutaceae) is effective against atopic dermatitis according to it's storage period. Methods : To evaluate antiallergic effect of CP and OCP (Old Citri Pericarpium) evaluated in vivo their inhibitory effects against passive cutaenous anaphylaxis (PCA) reaction induced by IgE-antigen complex and scratching behaviors by compound 48/80. The Anti-atopic effects were measured by contact dermatitis, prurient animal model and PCA reaction. Contact dermatitis in mice as a model of the Type IV reaction caused by Oxazolone. Results : The results showed that anti-pruritus effects, analgesic effects of CP was depends on its hesperetin contents. And It also showed that keep longer in storage appeared to be higher in hesperetin contents. Both CP and OCP(Old CP) have a dose-dependent analgesic action in acetic acid induced writhing syndrome. OCP Potently inhibited PCA reaction in mice, although OCP weakly inhibited in long term contact dermatitis model in mice. Conclusions : These results suggest that the Proportional to the storage period, Citri Pericarpium possesses analgesic effects and anti-allergic effects.
