  • Caragana sinica (Leguminosae) is a plant, which has been used as a traditional medicine for the treatment of lots of diseases including neuralgia, goat, hypertension and eczema. However, scientific studies of C. sinica in pharmacological aspects are not carried out. In this study, the anti-nociceptice effect of methanolic extract of C. sinica (MCS) was evaluated using various pain models. Our data represented that MCS significantly delayed the latency time under central pain condition which are arose from thermal stimuli, indicating MCS possess analgesic potential against central nociception. In addition, MCS showed strong and dose-dependent anti-nociceptive activities on acetic acid-induced peripheral pain, compared to positive control such as indomethacin. Further combination studies using naloxone, a non-selective opioid receptor antagonist, have revealed that analgesic activity of MCS was not changed in the presence of naloxone, indicating MCS exerts anti-nociceptive activity independent of opioid receptor. These results suggest that MCS may be an effective medicine in managing pain.

  • Some pharmacological activities of Ulmus davidiana var. japonica were evaluated using its methanol extract (UDE). An acute anti-inflammatory activity of UDE was assessed using carrageenan-induced hind paw edema in rats. UDE exhibited an antioxidant activity when assayed by a stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). Dose-dependent anti-nociceptive activity of UDE was assessed using the acetic acid-induced writhing test in mice. UDE was able to diminish the reactive oxygen species (ROS) level in the lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells. UDE also suppressed production of nitric oxide and induction of inducible nitric oxide synthase and cyclooxygenase-2 in the stimulated macrophages cells. collectively, the results imply that U. davidiana var. japonica has antioxidant and anti-nociceptive activities in addition to anti-inflammatory activity.

  • The current study aimed to assess some novel pharmacological activities of vanillin. Vanillin inhibited the chick chorioallantoic membrane (CAM) angiogenesis. Vanillin had anti-inflammatory activity using the acetic acid-induced permeability model in mice. Anti-nociceptive activity of vanillin was shown using the acetic acid-induced writhing test in mice. Vanillin inhibited production of nitric oxide (NO) and induction of inducible nitric oxide synthase (iNOS) but not cyclooxygenase-2 (COX-2) in the lipopolysaccharide (LPS)-activated RAW264.7 macrophages. Vanillin decreased the level of iNOS mRNA in the LPS-activated macrophages. Taken together, these results suggest that vanillin can have anti-angiogenic, anti-inflammatory and anti-nociceptive activities in ICR Mice.

  • We measured anti-nociceptive activity of prim-o-glucosylcimifugin (POG), a molecule from Saposhnikovia divaricate (Turcz) Schischk. Anti-nociceptive or anti-inflammatory effects of POG on a formalin-induced tonic nociceptive response and a complete Freund's adjuvant (CFA) inoculation-induced rat arthritis pain model were studied. Single subcutaneous injections of POG produced potent anti-nociception in both models that was comparable to indomethacin analgesia. Anti-nociceptive activity of POG was dose-dependent, maximally reducing pain 56.6% with an $ED_{50}$ of 1.6 mg. Rats given POG over time did not develop tolerance. POG also time-dependently reduced serum TNF${\alpha}$, IL-$1{\beta}$ and IL-6 in arthritic rats and both POG and indomethacin reduced spinal prostaglandin E2 ($PGE_2$). Like indomethacin which inhibits cyclooxygenase-2 (COX-2) activity, POG dose-dependently decreased spinal COX-2 content in arthritic rats. Additionally, POG, and its metabolite cimifugin, downregulated COX-2 expression in vitro. Thus, POG produced potent anti-nociception by downregulating spinal COX-2 expression.

  • Ribes fasciculatum (Saxifragaceae) has been widely used as a traditional medicine for the treatment of cough, antidote, cold, lacquer poison, and sore throat. In the present study, we evaluated the anti-nociceptive effects of ethyl acetate fraction of Ribes fasciculatum (ERF) in mice. Test results of tail-immersion test and hot plate test revealed that the ERF had strong anti-nociceptive activities on thermal nociception in a dose dependent manner, indicating ERF's anti-nociception on the central pain. Moreover, the acetic acid-induced chemical nociception was also significantly reduced by ERF treatment. This result shows that ERF may also work on the peripheral pain. We further performed formalin test to confirm ERF's anti-nociceptive properties and found that pain responses were significantly decreased by ERF treatment. Interestingly, in the combination test with naloxone, the analgesic activity of ERF was not changed, indicating that the opioid receptor was not involved in the ERF-mediated anti-nociception. These results indicate that ERF might be possibly used as a painkiller for the treatment of nociceptive pains.

  • Corylopsis gotoana has been widely used as a traditional medicine for the treatment of lots of disease including cold, edema and vomiting. However pharmacological and phytochemical studies on the C. gotoana are extremely limited. Here in this study, the author investigated the anti-nociceptive effects of the methanolic extract of Corylopsis gotoana (MCG) using various pain models. In the present study, MCG exhibited strong and dose-dependent anti-nociceptive activities on various experimental pain models including thermal nociception and chemical nociception, compared to positive control such as tramadol and indomethacin. In addition, the result from combination test using naloxone, analgesic activity of MCG was slightly reduced, indicating that MCG acts as a partial opioid receptor agonist. These results demonstrated that MCG has potent analgesic potential and thus it may be possibly used as a valuable anti-nociceptive agent.

  • The present study was designed to evaluate the anti-inflammatory and anti-nociceptive potential of the ethyl acetate fraction of Lindera glauca (ELG). We found that ELG significantly suppressed NO production through decreased enzyme activity and expression of iNOS in the IFN-γ/LPS-activated murine peritoneal macrophages. The treatment of ELG also down-regulated the expression of COX-2. Our western blot data revealed that inhibitory effects of ELG on these pro-inflammatory mediators were attributed to inactivation of NF-κB. In addition, ELG-fed mice showed a marked decrease in paw edema induced by subplantar injection of trypsin, suggesting in vivo anti-inflammatory potential of ELG. We further investigated the anti-nociceptive properties of ELG using thermal and chemical nociception model. We found that ELG has a strong anti-nociceptive activities in both central and peripheral mechanism. An additional combination test with naloxone revealed that opioid receptor was not involved in the ELG-mediated anti-nociception. In conclusion, ELG may possibly be used as valuable anti-inflammatory and anti-nociceptive agent for the treatment of inflammatory diseases and pains.

  • The current work was designed to assess novel pharmacological activities of 4-hydroxybenzaldehyde (HD), a major phenolic constituent of various natural products of plant origin, such as Gastrodia elata Blume. HD exhibited a significant inhibition in the chick chorioallantoic membrane (CAM) angiogenesis. HD also displayed an inhibitory effect in acetic acid-induced permeability in mice. Anti-nociceptive activity of HD was convinced using the acetic acid-induced writhing test in mice. HD was able to suppress production of nitric oxide (NO) and induction of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in the lipopolysaccharide (LPS)-activated RAW264.7 macrophages. HD also diminished the reactive oxygen species (ROS) level elevated in the LPS-activated macrophages. In brief, HD exhibits anti-angiogenic, anti-inflammatory and anti-nociceptive activities possibly via down-regulating iNOS and/or COX-2, which may be partly responsible for pharmacological efficacies of various natural products.

  • 4-Hydroxybenzaldehyde, a phenolic compound found in a variety of natural sources, was previously shown to contain anti-inflammatory and related anti-angiogenic and anti-nociceptive activities. The present work was designed to assess some pharmacological activities of 2,4-dihydroxybenzaldehyde (DHD), an analogue of 4-hydroxybenzaldehyde. DHD exhibited a significant inhibition in the chick chorioallantoic membrane (CAM) angiogenesis, and its $IC_{50}$ value was $2.4\;{\mu}g/egg$. DHD also contained in vivo anti-inflammatory activity using acetic acid-induced permeability and carrageenan-induced air pouch models in mice. In the air pouch model, DHD showed significant suppression in exudate volume, number of polymorphonuclear leukocytes and nitrite content. DHD showed an anti-nociceptive activity in the acetic acid-induced writhing test in mice. It also suppressed enhanced production of nitric oxide (NO) and elevated expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells. It was able to slightly decrease the level of reactive oxygen species in the stimulated macrophages. DHD at the used concentrations couldn't modulate the viabilities of RAW264.7 cells. Taken together, like 4-hydroxybenzaldehyde, DHD contains anti-angiogenic, anti-inflammatory and anti-nociceptive activities.

  • In this study, we evaluated the anti-nociceptive activities of Sorbus alnifolia. To investigate the anti-nociceptive properties of the methanolic extract of Sorbus alnifolia (MSA), we conducted several tests using various experimental mouse pain models. Herein, MSA significantly delayed the latency time and writhing motion in the hotplate test and acetic acid test, respectively. These result indicated that MSA has an ability to manage both peripheral and central nociception. We could further confirm the analgesic effects of MSA by performing formalin test. In combination test using naloxone, a non-selective opioid receptor antagonist, analgesic activity of MSA was partly antagonized by naloxone, but not completely, indicating that the MSA acts as a partial opioid receptor agonist. Out results suggest that the S. alnifolia may be possibly used as valuable anti-nociceptive agent.
