  • Dioscorea bulbifera is one of the traditional medicinal herb. It commonly used in the treatment of hematemesis, epistaxis, tuberculous cervical lymphadenitis, laryngitis, acute infectious disease in East Asia. In the present study, we have demonstrated the anti-inflammatory effects of Dioscorea bulbifera MeOH extract (DBME) in macrophage cell line. To investigate mechanism of the anti-inflammatory activity, we examined the effects of the lipopolysaccaride (LPS)-induced production of nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$), pro-inflammatory cytokines and expression of inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), p-inhibitory ${\kappa}B{\alpha}$ (p-$I{\kappa}B{\alpha}$), and nuclear factor-${\kappa}B$ (NF-${\kappa}B$) in a murine macrophage cell line RAW 264.7. The RAW 264.7 cells were cultured in DMEM + serum medium for 24 hrs. After serum starvation for 24 hrs, the cells were treated with DBME 0.03, 0.10, 0.30 mg/$m{\ell}$ for 1 h, followed by stimulation with LPS (1 ${\mu}g/m{\ell}$) for activation of immune response. After treatment, cell viability was measured by MTT assay, and NO production was monitored by measuring the nitrite content in culture medium. The protein band of iNOS, COX-2, p-$I{\kappa}B{\alpha}$, and NF-${\kappa}B$ was determined by immunoblot analysis and levels of cytokine were analyzed by sandwich immunoassays. There were three experimental groups: carrageenan, DBME 0.3, 1.0 g/kg. Rats were administrated either carrageenan (40% PEG) or carrageenan + DBME (0.3, 1.0 g/kg body weight) for 4 days (p.o.). To induce acute paw edema, rats were injected 1% carrageenan (100 ${\mu}{\ell}$/rat, dissolved in sterilized saline). The effect of DBME in the carrageenan-induced rat paw edema. As results, DBME has an inhibitory effect on the production of NO, PGE2, TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 and on the expression of iNOS, COX-2, p-$I{\kappa}B{\alpha}$ and translocation of NF-${\kappa}B$ to nuclear from cytosol. In addition, DBME effectively inhibited the increases of paw edema induced by carrageenan treatment in vivo. These results suggest that DBME can inhibit production of pro-inflammatory mediators and might be a useful source for treatment of acute inflammatory disease.

  • Background: Complex regional pain syndrome type I (CRPS-I) consists of disorders caused by spontaneous pain or induced by some stimulus. The objective was to verify the effects of photobiomodulation (PBM) using 830 nm wavelength light at the affected paw and involved spinal cord segments during the warm or acute phase. Methods: Fifty-six mice were randomized into seven groups. Group (G) 1 was the placebo group; G2 and G3 were treated with PBM on the paw in the warm and acute phase, respectively; G4 and G5 treated with PBM on involved spinal cord segments in the warm and acute phase, respectively; G6 and G7 treated with PBM on paw and involved spinal cord segments in the warm and acute phase, respectively. Edema degree, thermal and mechanical hyperalgesia, skin temperature, and functional quality of gait (Sciatic Static Index [SSI] and Sciatic Functional Index [SFI]) were evaluated. Results: Edema was lower in G3 and G7, and these were the only groups to return to baseline values at the end of treatment. For thermal hyperalgesia only G3 and G5 returned to baseline values. Regarding mechanical hyperalgesia, the groups did not show significant differences. Thermography showed increased temperature in all groups on the seventh day. In SSI and SFI assessment, G3 and G7 showed lower values when compared to G1, respectively. Conclusions: PBM irradiation in the acute phase and in the affected paw showed better results in reducing edema, thermal and mechanical hyperalgesia, and in improving gait quality, demonstrating efficacy in treatment of CRPS-I symptoms.

  • Objectives : Lespedeza Cuneata has been used to treat leukorrhea, asthma, stomach pain, diarrhea, acute mastitis, in Korean traditional medicine. According to recent studies, Lespedeza Cuneata has antioxidation, hypoglycemia, cell protective, insulin secretion, whitening, corpora cavernosa smooth muscle relaxation and antimicrobial activities, but it has been rarely conducted to evaluate the immuno-biological activity. The present study was examined to evaluate the anti-inflammatory effects of the Lespedeza Cuneata MeOH extract (LCE) in vivo and in vitro. Methods : In vitro, inflammatory mediators, such as cytokines, nitric oxide and prostaglandin $E_2$ were detected after the addition of LPS with or without LCE in Raw 264.7 macrophage cell line. In vivo, anti-edema effect of LCE was determined in the carrageenan-induced paw edema model in rats. Results : In vitro assay, LCE decreased release of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) via suppression of iNOS and COX-2 expression. LCE inhibited the phosphorylation of $I{\kappa}B$ indicating the suppression of NF-${\kappa}B$ pathway. In vivo assay, LCE significantly inhibited the formation of paw edema induced by carrageenan injection in rats. LCE effectively inhibited increases of hind paw skin thickness and inflammatory cell infilterations. Conclusion : These findings demonstrate that LCE has inhibitory effect on inflammatory mediators in LPS-activated Raw 264.7 cells and on paw edema in carrageenan-stimulated rats, showing the possibility of anti-inflammatory use of Lespedeza Cuneata.

  • Objectives This study was to investigate the effects of Yuhyangjeongtong-san on the carrageenin-induced acute inflammation and adjuvant-induced arthritis in rats. Methods Acute inflammation was induced by injection of 2% carrageenin 0.15 ml into right hind foot of rats. Control group was carrageenin injected and taken distilled water, treated group was carrageenin injected and taken Yuhyangjeongtong-san by orally once. 2 hours after injection, plantar temperature and paw volume were measured. 3 hours after, counts of white blood cell (WBC) were performed. Arthritis was induced by injection of complete freund's adjuvant (CFA) into base of tail. Control group was CFA injected and taken distilled water, treated group was CFA injected and taken Yuhyangjeongtong-san by orally for 10 days. 0,5,10 day, body weight, thickness of ankle joint and paw edema were measured. 10 day, counts of WBC, $interleukin-1{\beta}$ ($IL-1{\beta}$) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) level were analysed. Histochemical study of NADPH-d and immunohistochemical study of c-fos were performed. Results In the carrageenin-induced acute inflammation, neutrophils of treated group were significantly decreased compared with control group. In the adjuvant-induced arthritis, paw edema, total counts of WBC and TNF-${\alpha}$ level in paw exudates were significantly decreased compared with control group, and the number of c-fos positive neurons of treated group was significantly decreased compared with control group. Conclusions On the basis of these results, we concluded that Yuhyangjeongtong-san have anti-arthritic and anti-inflammatory effects.

  • Clerodendron trichotomum Thunberg Leaves (CTL) have been used for centuries in Chinese folk medicine for their anti-inflammatory properties. We have studied the anti-inflammatory effects of CTL extracts in rats, mice and in Raw 264.7 cells. 1 mg/kg solutions of the 30% and 60% methanol extracts of CTL were used and a 1 mg/kg of indomethacin was used as a positive anti-inflammatory standard; these were then administrated to rats. Carrageenan was injected subcutaneously to induce hind paw edema in rats. The result of carrageenan-induced rat paw oedema showed that a 1 mg/kg of the 30%, and 60% methanol fraction of CTL and 1 mg/kg of indomethacin inhibited the hind paw edema by 19.5%, 23.0%, and 20.5% respectively. The effect of CTL on inflammation in mice by a capillary permeability assay was examined by detecting Evans blue leakage from capillaries after the intraperitoneal injection of acetic acid, a potent inflammatory stimulus. The 60% methanol fraction of CTL inhibited Evans blue dye leakage by 47.0%, which was 10% higher than that of the inhibition of 1 mg/kg of indomethacin. Also, the 60% methanol fraction of CTL suppressed the prostaglandin $E_2$ ($PGE_2$) generation in RAW 264.7 macrophage cells after treatment with lipopolysaccharide (LPS) by as much as the inhibition of 1 mg/kg of indomethacin and this led to the synthesis of $PGE_2$ by COX-2 induction. The inhibition of the carrageenan-induced rat paw oedema, vascular permeability and the $PGE_2$ generation demonstrates that the 60% methanol fraction of CTL contains a potent anti-inflammatory activity.

  • Objectives : This study was designed to investigate the effects of extruded Acanthopanax Folium extracts on Complete Freund's Adjuvant (CFA) induced arthritis of rats. Methods: To induce arthritis in the ankle joint of rats, CFA was injected in the proximal part of the tail subcutaneously. After CFA injection, arthritic conditions were examined with macrography. The volume of paw edema and thickness of the ankle joints were checked regularly within 20 days. At 20 days, histopathological examination was performed on the ankle joint. Inflammation levels were determined by total WBC counts and differential WBC counts using a blood analyzer. Tumor necrosis factor-$\alpha$ and interleukin-1$\beta$ concentration in paw exudate were measured by ELISA method. Results: Several arthritic conditions induced by CFA were alleviated by Acanthopanax Folium treatment. Morphologically, reduction of arthritic conditions were observed and the volume of paw edema and thickness of the ankle joints were significantly decreased. Additionally, cytokines in paw exudate were diminished and histopathological improvement was observed. Conclusions: This study showed that the extruded Acanthopanax Folium extracts have the beneficial effects on the CFA induced arthritis of rats and might be used for chronic arthritis patients.

  • In this study, we prepared alcohol extracts of the larva, pupa, queen, and cocoon (clony) of B. ignitus, B. terrestris, and B. h. sapporoensis, and tested the anti-inflammatory activity of the extracts by using a rat model of adjuvant-induced edema. The extracts derived from the queen of B. ignitus, the queen of B. terrestris, and the cocoon of B. ignitus decreased hind paw edema after 1 day of i.p. administration. These extracts also induced vasorelaxation and NO production in calf pulmonary artery endothelial cells. These results suggest that bumblebee alcohol extracts has anti-inflammatory and vasorelaxant properties.
