Aqueous extreact of fresh ginseng (AFG) was examined for the antigenicity in Hartley guinea pigs in comparision with ovalbumin (OVA). When guinea pigs were sensitized with AFG emulsified with complete Freund's adjuvant (CFA), these animals showed negative reactions in active systemic anaphylaxis (ASA), active cutaneous anaphylaxis (ACA) and passive cutaneous anaphylaxis (PCA) tests and passive hemagglutination (PHA) reaction. On the contrary, when guinea pigs were sensitized with OVA emulsified with CFA as positive controls, these animals disclosed positive reactions in ASA, ACA and PCA tests and PHA reaction. From these results, AFG was considered not to possess antigenic properties in guinea pigs. In addition, the dose levels of AFG empolyed in the present experiment were confirmed not to suppress immune reactions.

This study was undertaken to investigate to know whether spleen and lymph node cells from immunized mice can transfer systemically the delayed-type hypersensitivity(DTH) reaction to Salmonella typhimurium and to characterize the lymphoid cells using glass, nylon wool and rabbit anti-mouse thymocyte serum. Mice, C57BL/6 or ICR, were immunized subcutaneously at 11, 8 and 2 days before adoptive systemic transfer with $100{\mu}g$ of protein antigen from S. typhimurium in complete Freund adjuvant. It was found that DTH reaction to S. typhimurium could be transferred to normal recipient systemically by both spleen and lymph node cells($10^8\;cells$, respectively) from immunized mice. The cells responsible for this transfer of DTH reaction were glass nonadherent T lymphocytes.

Alnus japonica (Betulaceae) has been traditionally used for purifying blood, and curing feces containing blood, enteritis, diarrhea, alcoholism and cut wounds. In the current work, activity guided isolation of the butanol fraction of the Alnus japonica bark led to the isolation of catechin-7-O-${\beta}$-D-apiofuranoside. Anti-inflammatory activity was determined with carrageenan-induced paw edema in mice as an acute inflammation, complete Freund's adjuvant-induced arthritis as a chronic inflammation. Carrageenan- induced paw edema in mice was significantly inhibited at 0.5, 1, 2, and 3 hr after carrageenan injection by administration of the flavonoid glycoside at the dose of 150mg/kg. (omitted)

Objectives The object of this study was to observe the favorable anti-arthritic effects of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) on Freund's complete adjuvant (FCA)-induced arthritic Wistar rats. Methods Rheumatoid arthritis was induced by intradermal injection of FCA, and 300, 150 or 750 mg/kg of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) were orally administered once a day for 14 days from 14 days after FCA treatments, and 15 mg/kg of dexamethasone was intraperitoneally administered as reference drug in this experiment. All rats were sacrificed at 14 days after continuous oral treatment of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) or intraperitoneal administration of dexamethasone, and changes on the body weight, knee circumferences, gross arthritis score, inflammatory tissue prostaglandin (PG) $E_2$ levels were monitored with cartilage collagen components and glucosaminoglycans compositions - chondroitin sulphate, heparan sulphate and hyaluronic acid in the present study. Results As results of FCA treatment, classic rheumatoid arthritis featuring dramatical decreases on the body weights, cartilage collagen contents and bone glucosaminoglycans-chondroitin sulphate, heparan sulphate and hyaluronic acid contents, with increases on the knee circumferences, gross arthritis scores and inflammatory tissue $PGE_2$ levels. However, these changes from FCA-induced rheumatoid arthritis were clearly reduced by treatment of dexamethasone and both two different dosages of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 and 150 mg/kg in the present study. Although FCA-induced arthritis were more favorably inhibited by treatment of dexamethasone 15 mg/kg as compared with Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg, marked decreases of body weights were detected in dexamethasone 15 mg/kg treated rats, and Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg showed similar preserve effects on the cartilage glucosaminoglycan compositions in this study. Conclusions The results obtained in this study suggest that over 300 and 150 mg/kg of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) showed favorable anti-arthritic effects on the FCA-induced arthritis mediated by suppression of $PGE_2$, a inflammatory mediator. However, detail mechanism studies should be conduced in future with the screening of the biological active compounds in this herb. Although overall anti-inflammatory effects Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg were lowered than those of dexamethasone 15 mg/kg treated rats, Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg treated rats showed similar preserve effects on the cartilage glucosaminoglycan compositions in this experiment.

Objectives : The object of this study was to observe the favorable anti arthritic effects of Euiiin-tang($y{\grave{i}}y{\breve{i}}r{\acute{e}}n-t{\bar{a}}ng$) aqueous extract(EIITe), has been traditionally used in Korean medicine for treating rheumatoid arthritis on collagen induced arthritic(CIA) DBA/1 mice. Methods : In the present study, effects of EIITe on the releases of human tumor necrosis factor(TNF)-${\alpha}$, interleukin(IL)-$1{\beta}$, matrix metalloproteinase(MMP)-13 and production of Nitric oxide(NO) were observed by in vitro. In addition, to observe the effects on the CIA mice, three different dosages of EIITe, 300, 150 and 150 mg/kg were orally administered once a day for 18 days from 24hrs after antigen challenges(type II collagen) on 21 days after immunization using Type II collagen Freund's complete adjuvant. Six groups, each of 8 DBA/1 mice per group were used in the present study as follows. Changes on the body weights, macroscopic arthritis scores, splenic weights, splenic TNF-${\alpha}$ and IL-6 contents, articular cartilage(femur and tibia) collagen and glycosaminoglycans-chondroitin sulphate, sulphate and hyaluronic acid contents, histopathological observations(microscopic arthritis scores, thicknesses of femur and tibia cartilage thicknesses were monitored, compared to that of dexamethasone, a potent anti inflammatory agents, 1 mg/kg treated mice. Results : As results of collagen challenges, marked decreases of body weights and gains, articular cartilage collagen and glycosaminoglycan - chondroitin sulphate, sulphate and hyaluronic acid contents were observed with increases of macroscopic arthritis scores, splenic weights, splenic TNF-${\alpha}$ and IL-6 contents, articular cartilage(in the both femur and tibia) loss and damages. However, these CIA signs were significantly and dosages dependently inhibited by treatment of EIITe 300 and 150 mg/kg as compared with CIA control, respectively. In addition, the releases of TNF-${\alpha}$, IL-$1{\beta}$, NO and MMP-13 were markedly and dose dependently inhibited by treatment of EIITe, invitro. Although CIA were more favorably inhibited by treatment of dexamethasone 1 mg/kg as compared with EIITe 300 mg/kg, marked decreases of body weights were detected in dexamethasone 1 mg/kg treated mice. Conclusions : The results obtained in this study suggest that over 150 mg/kg of EIITe showed favorable anti arthritic effects on the CIA mediated by immunomodulatory and/or anti oxidative effects. However, detail mechanism studies should be conduced in future with the screening of the biological active compounds in this herb. lthough CIA were more favorably inhibited by treatment of dexamethasone 1 mg/kg as compared with EIITe 300 mg/kg, marked decreases of body weights were detected in dexamethasone 1 mg/kg treated mice, in the present study.

Background: Discogenic pain can develop into chronic low back pain that is very difficult to treat effectively, because the pathogenesis of the disease still remains controversial. To clarify the pathogenesis, numerous animal models of intervertebral disc degeneration have been proposed in the literature, each with attendant advantages and disadvantages. The aim of this study was to determine the most efficacious method and dose of complete Freund's adjuvant (CFA) injection into intervertebral disc to develop a discogenic pain in a rat. Methods: CFA was injected into the L5-L6 or L4-L5 disc of male Sprague-Dawley rats in various conditions including a dose of CFA (10, 20, or 50 uL), drilling, injection site sealing using cyanoacrylate, and injection velocity. Sham animals were subjected to the same procedure, except for the CFA injection. Mechanical and heat allodynia were serially measured at both hindpaws until 8 weeks post-operatively. Serial MRI analyses were performed to observe degenerative changes of the discs. In addition, CGRP & Substance P-immunoreactivities (ir) in the superficial dorsal horn were evaluated at 4 weeks using immunohistochemistry. Results: Each condition provoked various problems such as development of hindpaw paralysis, CFA leakage, and no pain development. Mid-sagittal T2 MRI revealed no significant degenerative changes in the CFA injected disc. The CGRP-ir of the bilateral superficial dorsal horns at the level of L5-L6 was significantly increased in the CFA group. Conclusions: A total of 10 uL CFA injection into L5-L6 disc for a period of 10 minutes using a 26-gauge needle without drilling was the most efficacious way to develop discogenic pain animal model.

This study was performed to examine the antigenic potential of purified bee venom (Apis mellifera L., PBV) collected using bee venom collector. Antigenic potential of PBV was examined by active systemic anaphylaxis (ASA) in guinea pigs. PBV was subcutaneously administered at 0.025 and 0.05 mg/kg and also as a suspension with adjuvant (Freund's complete adjuvant, FCA). Ovalbumin (OVA) as a suspension with adjuvant was used to introduce positive control response. In the weight measurement and clinical observation, experimental groups didn't show any significant changes compared with control group. In the autopsy of body, the abnormalities of lung were detected only in the positive control. In the ASA test, experimental groups didn't show any symptoms of anaphylaxis like piloerection, hyperpnea and staggering gait. These results suggested that PBV didn't have antigenic potential in guinea pig.

Objective : Based on the immunological dysfunction in RA and the immunological feature of Clematis mandshurica Maxim. herbal acupuncture solution (CM-HAS), this study examined whether subcutaneous (s.c.) administration of CM-HAS has anti-inflammatory effects on adjuvant arthritis (AA) in the rat. Methods : Complete Freund's adjuvant was used to induce AA in rats. Secondary paw swelling of AA rats was measured, and polyarthritis index was scored. The administration of CM-HAS (2, 5, 10 mg/kg) to the Sinsu-hyul (BL 23) acupuncture point subcutaneously (s.c.) inhibited the inflammatory response and restored the weight of body and immune organs of AA rats. In this study. inhibitory effect of CM-HAS on cyclooxygenase-2 (COX-2) was evaluated. The plant material selected for this study has been used in Korean medicine for the treatment of various diseases that are considered as inflammatory in nature, e.g. asthma, arthritis, rheumatism, fever, edema, infections, snakebite and related inflammatory diseases. Results : There were significant secondary inflammatory reactions in AA rats, accompanied with the simultaneous decrease of body and immune organs weight. The administration of CM-HAS (2, 5, 10 mg/kg, s.c.) improved the above changes significantly. CM-HAS showed inhibitory activity against COX-2, which supports their traditional uses. In this study, aspirin and indomethacin were used to contrast with CM-HAS as the COX-2 inhibitors. Conclusion: The findings of this study may explain at least in part why CM-HAS has been traditionally used for the treatment of inflammatory conditions in traditional Korean and Chinese medicine.

The purpose of this study was to assess the effects of High-Voltage Pulsed Current (HVPC) and ultrasound on adjuvant-induced arthritis in rats. Adjuvant arthritis was induced in female Sprauge-Dawley rats by the subcutaneous injection of a single dose of $.1m{\ell}$ of Complete Freund's Adjuvant (CFA) (1 mg of Mycobacterium Butyricum suspended in $.1m{\ell}$ paraffin oil) into the right hind paw. A randomized, parallel-groups design of 24 subjects was used. All rats were randomly assigned to control (n=8), ultrasound (n=8), and HVPC (n=8) were compared with those of injured rats. The rats in the pulsed ultrasound group were treated at 1 MHz frequency with $.5W/cm^2$ intensity in 1:4 mode for 5 minutes per day. The rats in the HVPC group were treated at 120 pulses per second and $50{\mu}s$ phase duration, 20 mA intensity for 30 min per day. Treatment was done in the left and right hind limb for 2 weeks. We evaluated clinical, radiographic, hematologic and histopathologic findings before and after treatment and obtained the following results. 1. Edema of the right hind paw was more significantly reduced in the ultrasound and HVPC groups than the control group on days 9, 12, and 14 (p<.05). Edema of the left hind paw was more significantly reduced in ultrasound and HVPC groups than the control group on days 12, 14 (p<.05). 2. WBC counts of the ultrasound and HVPC groups as compared with the control group were becoming remarkably decreased after the treatment. 3. In radiologic findings, arthritis formation was seen according to the score of arthritis, which was the highest in the control group, upon the observation of radiographs of the left and right hind paws. However, no statistically significant difference was present in the score within three groups. 4. In the histopathologic findings, ultrasound and HVPC groups had effectively suppressed erosions of articular cartilage and inflammatory cell infiltrations. Therefore, the results of the study show that rats that were treated with the ultrasound and HVPC effectively suppressed adjuvant arthritis. However, no statistically significant difference was present between the ultrasound group and the HVPC group.
