  • In order to evaluate the improvement effects of head of Panax ginseng on chronic arthritis, we have investigated the activity of butanol fraction (BuOH fraction) in vitro and in vivo system. BuOH fraction showed significant inhibition on the elastase activity. Anti-arthritic activity of BuOH fraction was also examined on type II collagen-induced arthritis in DBA/1J mice. Mice were immunized with injection of type II collagen emulsified in Freund's complete adjuvant, followed by a booster injection 21 days later. BuOH fraction(BHPG) was administered at an oral dose of 500mg/kg for 2 weeks from the 1st day boost. The hind paw edema was significantly decreased in the group of treatment with BuOH fraction compared to control. In collagen-induced DBA/1J mice, BuOH fraction did not affected the collagen antibody titer but significantly inhibited the tumor necrosis factoralpha(TNF-${\alpha}$) activity. These results were confirmed with histological evaluation of joint tissues. This study may raise the possibility that the usage of BuOH fraction of head of Panax ginseng as alternative medicine for the relief and prevention of rheumatoid arthritis symptoms.

  • Ulmus parvifolia has been used as a traditional folk medicine to treat the carbuncle in deep skin. In this study, the effect of water extract of root bark of Ulmus parvifolia (WUP) on the carbuncle, pain, inflammation and hypersensitivity was evaluated in animal models. The administration of WUP significantly decreased the size of Staphylococcus aureus ($10^8$ cells/mouse)-induced carbuncle, and also exhibited analgesic activity in the HAc-induced writhing syndrome at doses of 50-500 mg/kg. It also showed significant anti-inflammatory activity in the carageenin- and complete Freund's adjuvant-induced inflammation. In the histamine-induced anaphylaxis, it decreased the percent of mortality by protecting mice treated with Bordetella pertussis. In the immune responses in the mice sensitized and challenged with sheep red blood cells, the Arthus reaction determined by swelling of foot pad at 4 h after challenge, HA titer, HY titer and PFC which can be used to evaluate the humoral immune response were significantly suppressed by oral administration of WUP at doses of 100 and 200mg/kg. The cellular immune responses in the same mice such as delayed type hypersensitivity determined by swelling of foot pad at 24 h after challenge and RFC were also significantly suppressed in the same manner.

  • Cnidii rhizoma is one of the most important crude drugs used particularly for the treatment of female genital inflammatory diseases in traditional oriental medicine. In this study, its anti-inflammatory and analgesic activities were examined employing animal models. It was found that $H_2O$ extract and n-BuOH fraction inhibited significantly the edema formation after the subplantar injection of carrageenin at oral doses of 100 and 200 mg/kg in a dose-dependent fashion, where MeOH extract showed significant anti-inflammatory activity at a oral dose of 200 mg/kg. In Freund's complete adjuvant-induced arthritis, H2O extract and n-BuOH fraction exerted their significant inhibitory activity on the edema formation at oral doses of 100 and 200 mg/kg. The $H_2O$ extract and n-BuOH fraction also showed significant analgesic activity in a dose-dependent manner in acetic acid-induced writhing test.

  • In the present paper, the immunostimulatory effects of Korean mistletoe (Viscum album Coloratum) on the non-specific immune responses of Japanese eel (Anguilla japonica) were examined. Eel were innoculated with mistletoe, Freund's complete adjuvant (FCA), or phosphate-buffered saline (PBS) as a control into their peritoneal cavities. The number of nitrobule tetrazolium (NBT)-positive cells in the head kidney of fish was significantly increased by the second day post-injection of mistletoe. ROI products were more enhanced in mistletoe-injected fish kidney leucocytes than in FCA-injected ones. The level of lysozyme activity detected in the serum of fish 2 days after injection with mistletoe was also significantly higher than that found in the serum of the control fish. The appropriate concentration of mistletoe to induce the highest level of serum lysozyme activity was revealed to 1000${\mu}g$/200 g of fish. In phagocytic activity assay, mistletoe-sensitized eel kidney phagocytes captured more zymosan than did the control fish. Korean mistletoe appeared to be a good activator of the non-specific immune responses of Japanese eel.

  • To elucidate the involvement of interleukin-$1{\beta}$ converting enzyme (ICE) in the course of experimental autoimmune encephalomyelitis (EAE), we induced EAE by immunizing rats with an emulsion of rat spinal cord homogenate with complete Freund's adjuvant supplemented with Mycobacterium tuberculosis (H37Ra, 5mg/ml) and then examined the expression of ICE in the spinal cord of rats with EAE. In normal rat spinal cords, ICE is constitutively, but weakly, expressed in ependymal cells, neurons, and some neuroglial cells. In EAE, many inflammatory cells are positive for ICE, and the majority of ICE+ cells were identified as ED1+ macrophages. During this stage of EAE, the number of ICE+ cells in brain cells, including neurons and astrocytes, increased and these cells also had increased ICE immunoreactivity. These findings suggest that the upregulation of ICE in both brain cells and invading hematogenous cells is stimulated by a secretory product from inflammatory cells, and that this enzyme is involved in the pathogenesis of EAE via the production of IL-1 beta.

  • Objectives : To investigate the role of Meridian flow on acupuncture effect, we observed the therapeutic effects of electroacupuncture (EA) after Meridian blocking with pressure in arthritic rats. Methods : To make reliable and local monoarthritis, $40{\;}{\mu}l$ complete Freund's adjuvant was injected into the tibio-tarsal joint. EA was applied on acupoint GB30 while 5 Pascal pressure was added to the middle of the Gall bladder Meridian around GB31 between acupoint GB30 and arthritic foci (ipsilateral meridian blocking: IB) or opposite part of IB (contralateral part blocking: CB). To observe the change of arthritis, extension and flexion pain scores and circumferential differences were evaluated once a week. Results : EA stimulation without blocking reduced arthritic pain significantly. IB abolished the acupuncture effects and there was no statistical difference with the arthritic control group, whereas the CB group still showed the therapeutic effects of acupuncture. Conclusions : This finding strongly supports that the Meridian blocking with local pressure reduced the therapeutic effect of EA.

  • A polymorphic fungus, Candida albicans, causes various forms of infections such as disseminated candidiasis and vaginitis. Recent reports indicate that the fungus is a main etiological agent for the arthritis. In search of new sources for treatment of the fungal arthritis, we examined $18{\beta}$-glycyrrhetinic acid ($18{\beta}$-GA) against C. albicans-caused septic arthritis. The compound is isolated from Glycyrrhizae Radix that is known to have various immunomodulating activities and is one of the most popular herbal medicines. For induction of animal model of a septic arthritis, mice were given an emulsion form of C. albicans cell wall mixed with Complete Freund's Adjuvant (CFA) via footpad-injection. To determine prophylactic and therapeutic effects, the component was given to the animals before or after the induction of the arthritis, respectively. Data showed that intraperitoneal administration of $18{\beta}$-GA resulted in reduction of the inflammation, indicating the component had both prophylactic and therapeutic activities. For investigation of mechanism of the $18{\beta}$-GA, inhibitory effects on NO (nitiric oxide) and on T-lymphocyte proliferation were determined. Results demonstrated that $18{\beta}$-GA suppressed NO production from LPS (lipopolysaccharide)-treated macrophages and also inhibited proliferation of Con A (concanavalin A)activated T-cells. Taken together, $18{\beta}$-GA, a pentacyclic triterpene, has anti-arthritic activity against C. albicans-caused septic arthritis, possibly by blocking NO production and T-cell suppression.

  • The anti-inflammatory effects of glycosaminoglycan (GAG) derived from Isaria sinclairii (IS) and of IS extracts were investigated in a complete Freund's adjuvant (CFA)-treated chronic arthritis rat model. Groups of rats were treated orally with 30 mg/kg one of the following: [1] saline control, extracts of [2] water-IS, [3] methanol-IS, [4] butanol-IS, [5] ethyl acetate-IS, or [6] Indomethacin(R) as the positive control for a period of two weeks. The anti-paw edema effects of the individual extracts were in the following order: water-IS ex. > methanol ex. > butanol ex. > ethyl acetate ex. The water/methanol extract from I. sinclairii remarkably inhibited UV-mediated upregulation of NF-${\kappa}B$ activity in transfected HaCaT cells. GAG as a water-soluble alcohol precipitated fraction also produced a noticeable anti-edema effect. This GAG also inhibited the pro-inflammatory cytokine levels of prostaglandin $E_2$-stimulated lipopolysaccharide in LAW 264.7 cells, cytokine TNF-${\alpha}$ production in splenocytes, and atherogenesis cytokine levels of vascular endothelial growth factor (VEGF) production in HUVEC cells in a dose-dependent manner. In the histological analysis, the LV dorsal root ganglion, including the articular cartilage, and linked to the paw-treated IS GAG, was repaired against CFA-induced cartilage destruction. Combined treatment with Indomethacin(R) (5 mg/kg) and IS GAG (10 mg/kg) also more effectively inhibited CFA-induced paw edema at 3 hr, 24 hr, and 48 hr to levels comparable to the anti-inflammatory drug, indomethacin. Thus, the IS GAG described here holds great promise as an anti-inflammatory drug in the future.

  • This study was performed to observe the influence of host immune response on the chemotherapy of mice experimentally infected with Fasciola hepatica. Following immunosuppression with prednisolone or immunoenhancement with Freund's complete adjuvant(FCA), mice were experimentally infected with 3 Fasciola hepatica metacercariae and treated with closantel at 1 week post infection. In the group of mice infected with metacercariae alone, 2 mice of 10 were dead at 10 weeks post infection(20% mortality), and adult flukes were recovered from the liver and the peritoneal cavity of the remaining 8 mice(100% infectivity). In the group of mice treated with prednisolone and infected with metacercariae, 8 of 10 mice died before euthanasia with a mean time of death earlier than the control group (p<0.05). In the group of immunosuppressed mice infected with metacercariae and treated with closantel 20mg/kg, 4 of 10 mice died before sacrifice. In the group of mice infected and treated with closantel 20mg/kg, mortality and infectivity was 10% and 30%, respectively. Similar results were observed in mice infected and treated with closantel 5mg/kg which resulted in 10% and 50% mortality and infectivity, respectively. These results indicated that the efficacy of closantel treatment was decreased in immunosuppressed mice, while the pathogenicity was increased. In immunoenhanced mice infected with metacercariae, on the other hand, the efficacy of chemotherapy with both 5mg/kg or 20mg/kg closantel resulted in only 10% infectivity. The results shown in this study strongly suggest that a close interaction between chemotherapy against F hepatica with closantel and the host immune system exists. Considering that fascioliasis is a zoonosis, treatment regimen against the infection to immunosuppressed patients may require a concurrent prescription of an appro-priate immuno-enhancing adjuvant.

  • GCSB-5 is a purified extract from a mixture of 6 Oriental herbs (Ledebouriellae Radix, Achyranthis Radix, Acanthopanacis Cortex, Cibotii Rhizoma, Glycine Semen, and Eucommiae Cortex) that have been widely used for the treatment of inflammatory diseases in the East Asia. The aim of this study was to investigate the anti-inflammatory potential of GCSB-5. The animals used in this study were administered either vehicle or GCSB-5 (30, 100, 300, and 600 mg/kg) orally. The GCSB-5 significantly inhibited the increased of acetic acid-induced vascular permeability (30.9%-34.2% inhibition at 30-300 mg/kg). The swelling of the rat's hind paw induced by carrageenan was significantly inhibited by GCSB-5 in doses of 100, 300, and 600 mg/kg. Maximal inhibition (50.9%) was obtained with GCSB-5 at dose of 300 mg/kg. However, it did not have any anti-inflammatory action in the rheumatoid arthritis induced by Freund's complete adjuvant or in the granuloma induced by carrageenan. Our finding suggest that GCSB-5 has a anti-inflammatory activity.
