MeOH extract of Kochia scoparia was fractionated into $CHCl_3-$, EtOAc- and BuOH extracts and the last fraction were hydrolyzed by 3%-NaOH ($MeOH-H_2O$) to compare the bioactivities on antinociceptive and anti-inflammatory effects. Silica gel column chromatography of BuOH fraction afforded a large amount of $3-Ο-{\beta}-D-xylopyranosyl {\;}(1{\rightarrow}3)-{\beta}-D-glucuronopyranosyl$ oleanolic acid (momordin Ic, 4) and that of acid hydrolysate of BuOH fraction gave $3-Ο-{\beta}-D-glucuronopyranosyl oleanolic$ acid (momordin Ib, 3), its 6'-Ο-methyl ester (2) and oleanolic acid (1). Silica gel column chromatography of alkaline hydrolysate afforded a large amount of 4. MeOH extract and both EtOAc- and BuOH fractions were active in the rheumatoidal rat induced Freund's complete adjuvant reagent (FCA) whereas $CHCl_3$ fraction was inactive. Compound 1 and 4 showed significant activities in the same assay but oleanolic acid 3-Ο-glucuronopyranoside (3) showed no activity. These fashions were also observed in carrageenan-induced edema of the rat and in the antinociceptive activity tests undertaken in hot plate- and writhing methods. These results suggest that momordin Ic and its aglycone, oleanolic acid, could be active principles for rheumatoid arthritis.

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 Theileria sergenti soluble merozoite preparation containing the 29, 34, 35 and 105 KD as the immunodominant polypeptides, was evaluated for efficacy, safety and protectivity in Holstein calves against virulent field tick challenge. The soluble antigens (100 mg/dose) were fortified with either complete or incomplete Freund's adjuvant. Twenty naive calves, aged one month, were subcutaneously inoculated with the preparation and a booster dose was administered 4 weeks later. Twenty additional calves served as controls. Five weeks after the booster dose, vaccinates and uninoculated controls were moved to a pasture, a heavily tick infested area in Cheju-do, Korea. The vaccinates showed negligible change in hematocrit and total RBC count whereas control animals showed significant (p<0.05) hematological changes and associated anemia. Only 30% of vaccinates required chemotherapy after the experiment was terminated. All control animals required chemotherapy and 25% received blood transfusion. The highest percent parasitized erythrocytes in vaccinated cattle was 0.4% as compared with 3.6% among controls during the month of July. A significant difference (p<0.05) was observed in the rate of body weight increase. Significant difFerences were also noted in serum albumin, aspartate aminotransferase, total protein and bilirubin. Significantly more vaccinated cattle maintained normal ranges of hematological and biochemical values as compared with the control group. It is suggested that soluble merozoite T. sergenti antigens may be potential vaccine candidates for developing a genetic vaccine in Korea.

The effect of a chronic inflammation (cell-mediated immune response) on energy metabolism and growth performance was assessed in weanling piglets. Twenty four barrows of 4 wk of age were assigned to one of two immunization treatments : Control group [CON: immunized with Incomplete Freund's Adjuvant (lFA)] or Immunization group [IMMU: immunized with Complete Freund's Adjuvant (CFA)]. On d0, piglets were weaned and subcutaneously immunized at the medial side of the femur with 2 ml of IFA or CFA, respectively. Energy and nitrogen balances were measured per group during 13-d balance period, and total $(HP_{tot})$, activity-related ($(HP_{act})$) and non-activity-related $(HP_{cor})$ heat production were determined every 9-min by indirect calorimetry. Ig total titers to Mycobacterium butyricum, which is present in CFA, were higher (p<0.01) in IMMU than in CON on d13 (2.5 vs 1.8) and d20 (2.9 vs 1.8) after immunization. There were no differences (p>0.10) between treatments in rectal temperature, performance, feed intake, and availability and partitioning of energy during the balance period. Average daily feed intake was numerically higher in IMMU than in CON (0.34 vs 0.32 kg/d), but there was no difference (p>0.10) in metabolizability of the dietary energy between treatments. $HP_{act}/HP_{tot}$ was 16.24 and 16.89%, and retained energy was 251 and 268 $268\;kJ{\cdot}kg^{0.75}{\cdot}d^{-1}$ for CON and IMMU, respectively. Numerically, maintenance requirement of IMMU was even lower than that of CON $(419\;vs\;427\;kJ{\cdot}kg^{0.75}{\cdot}d^{-1})$. The present study suggests that a chronic inflammation has no effect on energy metabolism and growth performance, in spite of the difference in systemic antibody responses. The reason was considered to be due to locally induced immune response, resulting from the possible encapsulation at the site of injection, and/or to a low systemic immune stress which is within a functionally acceptable physiological range for the piglets.

The effect of beta-glucan ($Polycan^{TM}$) derived from Aureobasidium pullulans SM-2001 were observed on, collagen-induced rheumatoid arthritis (RA) in DBA mice. Six week-old male DBA/1J mice were immunized by the intradermal injection of $200\;{\mu}g$ of bovine type II collagen with the equal volume of complete Freund's adjuvant at the tail base on day 1. On day 21, the mice were boosted by the intradermal injection of $200\;{\mu}g$ of bovine type II collagen with incomplete Freund's adjuvant. From the first immunization, mice had been administered $Polycan^{TM}$ (21.25, 42.5 and 85 mg/kg), diclofenac and vehicle once a day for 4 weeks, respectively. Collagen-induced hyperimmunities and arthritis signs were markedly and dose-dependently inhibited by treatment of $Polycan^{TM}$ compared with RA control except for tibial cartilages of $Polycan^{TM}$ 21.25 group. $Polycan^{TM}$ effectively inhibited the histopathological changes of collagen-induced arthritis and hyper-immunities.

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.
