  • Objectives: Warm needling combines simultaneously the effects of acupuncture and moxibustion. This study was to investigate whether warm needling could relieve acute knee arthritis induced by carrageenan in rats. Methods: To illuminate the underlying mechanisms of the warm needling-induced antinociception, weight bearing force (WBF) was observed on the acute knee arthritic rat model. Under general anesthesia, ST36, SP9, Hakjung extra point, LI4 were punctured and stimulated with 30 mg moxa ball combustion on top of the needle (${\emptyset}0.18{\times}8mm$). Results: In behavioral test, rats subsequently showed a reduced stepping force of the affected limb 3 hours after the induction of arthritis. Warm needling on the contralateral or ipsilateral ST36 failed to show antinociceptive effect on the acute knee arthritis. Warm needling on the contralateral SP9 or LI4 increased WBF values to normal level in the acute stage of the arthritis. Warm needling on the Hakjung extra-point resulted in the significant antinociceptive effects through acute stage. These effects of warm needling were suppressed by opioids receptor antagonist naltrexone (10 mg/kg, i.p.) and alpha adrenoceptor antagonist phentolamine (5 mg/kg, i.p.). Conclusion: The data suggest that warm needling-induced antinociception is differently mediated by acupoints and accomplished by activating the descending inhibitory systems including endogenous opioids and $\alpha$-adrenoceptors.

  • Objectives: The warm needling technique is a method which combines the effects of acupuncture with those of moxibustion. The purpose of this study was to find the stimulus effects of a high frequency warm needling device when stimulating acupoint $LI_4$ on the carrageenan-induced arthritis. Methods: This study was to observe the effects to edema reaction, WBF(weight bearing force), NO concentration, nNOS expression after the electro high frequency stimulus of high frequency warm needling device on LI4 with insulated acupuncture needle. Results: The effect of the high frequency warm needling device is to rise up the temperature in proportion to the current intensity. After stimulating on the acupoint $LI_4$ of the carrageenan-induced arthritis in rats with the high frequency warm needling device, it significantly reduced edema in the rat's foot. In addition, WBF, NO concentration of spinal cord (nmol/mg), and nNOS relative expression were reduced. Conclusions: The above results support the idea that stimulus by the high frequency warm needling device on $LI_4$ produces a potent analgesic effect in the arthritis pain model of the rat. Moreover, stimulus by the high frequency warm needling device modulates endogenous NO through the suppression of nNOS protein expression.

  • This study was performed to examine the possibility of water extracts for several medicinal plants, such as Amomum tsao-ko, Alpinia oxyphylla, and Citrus unshiu, as an active packaging ingredient for prevention of lipid oxidation. Chicken breast meats were packed with medicinal plant extracts incorporated carrageenan based films and their physico-chemical and microbial properties during storage at $5^{\circ}C$ were investigated. In chicken meat samples packed with A. tsao-ko (TF) or A. oxyphylla (OF) extract incorporated carrageenan based films, pH value, thiobarbituric acid reactive substances (TBARS), and the population of total microbes were significantly lower than those of the negative control (film of no extract was incorporated, CF) after 5 d of storage (p<0.05). Especially, TBARS value of TF ($0.12{\pm}0.01$ mg malonaldehyde/kg meat) was significantly lower than chicken meat samples packed with positive control (ascorbic acid incorporated film, AF, $0.16{\pm}0.01$ mg malonaldehyde/kg meat) at 3 d of storage, and it means TF has enough antioxidative activity to prevent the lipid oxidation of chicken meat. However, there was no consistent effect on VBN values of chicken meats packed with medicinal plant extracts incorporated films during storage. Based on the obtained results, it is considered that A. tsao-ko extract has potential for being used as a natural antioxidant ingredient in active packaging areas.

  • The 12 kDa FK506-binding protein (FK506BP12), an immunosuppressor, modulates T cell activation via calcineurin inhibition. In this study, we investigated the ability of PEP-1-FK506BP12, consisting of FK506BP12 fused to the protein transduction domain PEP-1 peptide, to suppress catabolic responses in primary human chondrocytes and in a mouse carrageenan-induced paw arthritis model. Western blotting and immunofluorescence analysis showed that PEP-1-FK506BP12 efficiently penetrated chondrocytes and cartilage explants. In interleukin-1β (IL-1β)-treated chondrocytes, PEP-1-FK506BP12 significantly suppressed the expression of catabolic enzymes, including matrix metalloproteinases (MMPs)-1, -3, and -13 in addition to cyclooxygenase-2, at both the mRNA and protein levels, whereas FK506BP12 alone did not. In addition, PEP-1-FK506BP12 decreased IL-1β-induced phosphorylation of the mitogen-activated protein kinase (MAPK) complex (p38, JNK, and ERK) and the inhibitor kappa B alpha. In the mouse model of carrageenan-induced paw arthritis, PEP-1-FK506BP12 suppressed both carrageenan-induced MMP-13 production and paw inflammation. PEP-1-FK506BP12 may have therapeutic potential in the alleviation of OA progression. [BMB Reports 2015; 48(7): 407-412]

  • The chloroform extract of Croton roxburghii (Family: Euphorbiaceae) was evaluated for its antipyretic effects in Brewer's yeast induced hyperthermia in rats. The anti-inflammatory effect of the Croton roxburghii was also evaluated by using carrageenan, dextran, histamine, serotonin induced rat paw oedema and cotton pellet induced granuloma (chronic) models in rats. The chloroform extract of Croton roxburghii (CECR) exhibited significant anti-pyretic and anti-inflammatory effect at the dose 50, 100 and 200 mg/kg. Maximum inhibition (55.32%) was notedat the dose of 200 mg/kg after 3 h of drug treatment in carrageenan induced paw oedema, whereas the Indomethacin (standard drug) produced 61.33% of inhibition. The extract exhibited significant anti-inflammatory activity in dextran induced paw edema in a dose dependent manner. In the chronic model (cotton pellet induced granuloma) the CECR (200 mg/kg) and Indomethacin (10 mg/kg) showed decreased formation of granuloma tissue by 52.32% and 56.32% respectively. The extract also exhibited a significant antipyretic response in Brewer's yeast induced pyrexia in rats. Thus, the present study revealed that the CECR exhibited significant antipyretic and anti-inflammatory activity in the tested animal models.

  • The purpose of this study is to develop a continuous process for sorbitol production using Zymomonas mobilis immobilized in K-carra-geenan. The glutaraldehyde cross-linking of toluene-treated cells immobilized in alginate or chitin showed high enzyme stability for long period. However, loss of enzyme activity was observed at 23% during 210h. In order to investigate the stability of glucose-fructose oxidoreductase of cethyltrimethylammoniumbromide (CT AB) treated cells, the long term continuous process was carried out with Z. mobilis immobilized in K-carrageenan in the continuous stirred tank reactor(CSTR) and the packed bed reactor. The continuous production of sorbitol with the immobilized CT AB permeabilized cells in packed bed reactor was more stable than in CSTR. Two stage continuous process with CT AB treated cells of Z. mobilis immobilized in K-carrageenan was carried out at various dilution rates. At the first stage, the productivity was increased up to 15 g/ $\ell$ -h as dilution rate increased and decreased over 0.32$h^{-1}$ of dilution rate. Similarly, maximum productivity obtained at the second stage was 22g/$\ell$ -h at 0.32$h^{-1}$

  • A bacterial strain capable of hydrolyzing carrageenan was isolated from the coast of Busan in Korea. The isolated strain (HS5322) is aerobic, gram-negative, rod-shaped, and motile. Comparison of the 16S rDNA of the isolate with that of known Pseudomonas sp. showed that sequence similarity was at most 95%, implying that the isolate is a new Pseudomonas species. The organism grew optimally at NaCl concentrations of 2.0 to 2.5%. The optimum temperature and pH for carrageenase production in a 72-h flask culture containing 1% carrageenan was $20^{\circ}C$ and pH 8.5, respectively. Of the synthetic substrates tested, the highest enzyme activity was obtained with p-nitrophenyl ${\beta}$-D-galactopyranoside.

  • Curcumin, a dietary pigment responsible for the yellow color of curry, has been used for the treatment of inflammatory diseases and exhibits a variety of pharmacological effects such as anti- inflammatory, anti-tumor, anti-oxidant, and anti-viral activity. In order to examine the potency of the curcumin in inflammation we used carrageenan induced rat hind paw odema model. As curcumin is practically water insoluble, it is hypothesized that pharmacological activity of curcumin could be improved by enhancing its water solubility. Water soluble complexes of curcumin with cyclodextrins were prepared and screened for greater solubility. Pure curcumin 100 mg/kg body weight along with curcumin complexes equivalent to 100 mg/kg body weight of pure curcumin were tested for the anti-inflammatory activity in Wister rats male rats using carrageenan induced hind paw edema model and compared with that of the reference compound diclofenac sodium at a dose level of 10 mg/kg body weight. Results were statistically analyzed using ANOVA. All the treatment groups showed statistically significant anti-inflammatory activity compared with that of vehicle control and positive control.

  • Angelicas Tenuissimae Radix (ATR) has traditionally been used for flu-like symptoms, limb-ache and disability, and even for toothache. In the present study, the effect of ATR on carrageenan-induced edema, acetic acid-induced abdominal pain, and heat-induced hyperalgesia were investigated using rats and mice. In the present results, ATR reduced carrageenan-induced edema in rats and inhibited acetic acid-induced abdominal pain in mice. Here in this study, we have shown that ATR possesses anti-inflammatory and analgesic effects.

  • BACKGROUND/OBJECTIVES: Overproduction of nitric oxide (NO) by the inducible nitric oxide synthase (iNOS) enzyme can cause inflammation. Cyclooxygenase-2 (COX-2) is also involved in the inflammatory response through regulation of nuclear factor-kappa B $NF-{\kappa}B$(). Areca catechu is one of the known fruit plants of the Palmaceae family. It has been used for a long time as a source of herbal medicine in Indonesia. In this study, we explored the effect of Indonesian Areca catechu leaf ethanol extract (ACE) in lipopolysaccharide (LPS)-induced inflammation and carrageenan-induced paw edema models. Recently, this natural extract has been in the spotlight because of its efficacy and limited or no toxic side effects. However, the mechanism underlying its anti-inflammatory effect remains to be elucidated. MATERIALS/METHODS: We measured NO production by using the Griess reagent, and determined the expression levels of inflammation-related proteins, such as iNOS, COX2, and $NF-{\kappa}B$, by western blot. To confirm the effect of ACE in vivo, we used the carrageenan-induced paw edema model. RESULTS: Compared to untreated cells, LPS-stimulated RAW 264.7 cells treated with ACE showed reduced NO generation and reduced iNOS and COX-2 expression. We found that the acute inflammatory response was significantly reduced by ACE in the carrageenan-induced paw edema model. CONCLUSION: Taken together, these results suggest that ACE can inhibit inflammation and modulate NO generation via downregulation of iNOS levels and $NF-{\kappa}B$ signaling in vitro and in vivo. ACE may have a potential medical benefit as an anti-inflammation agent.
