The present study was undertaken to confirm whether melittin, a major constituent of whole bee venom (WBV), had the ability to produce the same nociceptive responses as those induced by WBV. In the behavioral experiment, changes in mechanical threshold, flinching behaviors and paw thickness (edema) were measured after intraplantar (i.pl.) injection of WBV (0.1 mg & 0.3 mg/paw) and melittin (0.05 mg & 0.15 mg/paw), and intrathecal (i.t.) injection of melittin $(6{\mu}g)$. Also studied were the effects of i.p. (2 mg & 4 mg/kg), i.t. $(0.2{\mu}g\;&\;0.4{\mu}g)$ or i.pl. (0.3 mg) administration of morphine on melittin-induced pain responses. I.pl. injection of melittin at half the dosage of WBV strongly reduced mechanical threshold, and increased flinchings and paw thickness to a similar extent as those induced by WBV. Melittin- and WBV-induced flinchings and changes in mechanical threshold were dose- dependent and had a rapid onset. Paw thickness increased maximally about 1 hr after melittin and WBV treatment. Time-courses of nociceptive responses induced by melittin and WBV were very similar. Melittin-induced decreases in mechanical threshold and flinchings were suppressed by i.p., i.t. or i.pl. injection of morphine. I.t. administration of melittin $(6{\mu}g)$ reduced mechanical threshold of peripheral receptive field and induced flinching behaviors, but did not cause any increase in paw thickness. In the electrophysiological study, i.pl. injection of melittin increased discharge rates of dorsal horn neurons only with C fiber inputs from the peripheral receptive field, which were almost completely blocked by topical application of lidocaine to the sciatic nerve. These findings suggest that pain behaviors induced by WBV are mediated by melittin-induced activation of C afferent fiber, that the melittin-induced pain model is a very useful model for the study of pain, and that melittin-induced nociceptive responses are sensitive to the widely used analgesics, morphine.

Allergic skin inflammation such as atopic dermatitis is characterized by skin barrier dysfunction, edema, and infiltration with various inflammatory cells. The anti-inflammatory effects of Apo-9'-fucoxanthinone, isolated from Sargassum muticum, have been described in many diseases, but the mechanism by which it modulates the immune system is poorly understood. In this study, the ability of Apo-9'-fucoxanthinone to suppress allergic reactions was investigated using a mouse model of atopic dermatitis. The Apo-9'-fucoxanthinone-treated group showed significantly decreased immunoglobulin E in serum. Also, Apo-9'-fucoxanthinone treatment resulted in a smaller lymph node size with reduced the thickness and length compared to the induction group. In addition, Apo-9'-fucoxanthinone inhibited the expression of interleukin-4, interferon-gamma and tumor necrosis factor-alpha by phorbol 12-myristate 13-acetate and ionomycin-stimulated lymphocytes. These results suggest that Apo-9'-fucoxanthinone may be a useful therapeutic strategy for treating chronic inflammatory diseases.

In the present study, the anti-inflammatory effect of "Jungcheonhwadamgangki-tang ga Antler" water extract was tested in Xylene-Application mouse ear acute inflammation model. The test articles were once dosed before Xylene-Application, and the changes on body weight and ear weights and histopathological observation of induced ear were conducted with ear histomorphometry. The obtained results were as follows. The increases of absolute and relative ear weight detected in vehicle control compared to that of sham, were significantly and dose-dependently inhibited by Jungcheonhwadamgangki-tang ga Antler in the present study. A classic acute inflammatory histological changes such as subcutaneous edema, thickness and infiltration of inflammatory cells, was detected in vehicle control. However, these histological changes were significantly and dose-dependently inhibited by Jungcheonhwadamgangki-tang ga Antler. In addition, the increases of ear thickness half and thickness full detected in the vehicle control were also dose-dependently decreased in the all Jungcheonhwadamgangki-tang ga Antler-dosing groups. Base on these results, it is concluded that Jungcheonhwadamgangki-tang ga Antler extracts has clear anti-inflammatory effect on the acute inflammation such as bronchial asthma.

This study was conducted to determine if YJ-1, a novel herbal complex from a mixture of six oriental herbs (Hydnocarpi Semen, Sesami Semen, Dictamni Radicis Cortex, Momordicae Semen, Xanthii Fructus, and Sophorae Radix), has therapeutic properties for the treatment of atopic dermatitis (AD). Using AD like symptom-induced NC/Nga mice by 1-chloro 2,4-dinitrobenzene (DNCB), the effectiveness of YJ-1 on AD was evaluated. Elidel cream$^{(R)}$ (1% pimecrolimus) was used as a control. Dermal application of YJ-1 reduced major clinical signs of AD such as erythema, pruritus, lichenification, edema/escoriations, and dryness. Interestingly, YJ-1 more improved AD-related symptoms including decrease of spleen weight, IL-4, and IgE level in the serum as well as reduction of scratching counts and clinical skin severity in the NC/Nga AD mouse model. Especially, treatment of YJ-1 at 20% in NC/Nga mice more effected than Elidel cream. These results suggest that the ointment of YJ-1 may enhance the process of AD healing by alleviating allergic reaction and has potential for therapeutic reagent for the treatment of AD.

Radix Paeoniae rubra (PR) has been widely used for recovering acute inflammation with swelling and pain in Far East Asian countries. In order to investigate the anti-arthritic effect of PR herbacupuncture, several behavioral parameters such as body weight, knee circumference, squeaking threshold, and weight distribution ratio were investigated in an adjuvant-induced mono-arthritis rat model. We performed PR herb-acupuncture on Zusanli (ST36) of the right hind-leg once every second day for a total of 6 times from the second day of initiating arthritis with adjuvant injection, while the control group was treated with saline in the same way. In the experimental group, body weight significantly increased, knee circumference and squeaking threshold significantly decreased indicating the reduction of edema, and both the pain and inflammatory swelling of the hind paws measured by incapacitance meter decreased. Conclusively, PR herb-acupuncture has more promising effect in alleviating arthritic pain and inflammation than saline-acupuncture in rat model, hence further clinical study is required.

Objectives : Auklandia Lappa (ALE) is one of the herbs used frequently to treat abdominal pain and diarrhea and reported anti-inflammatory activity by suppressing proinflammatory cytokines. This study was designed to investigate whether ALE could show protective activities on experimental colitis induced by dextran sulfate sodium (DSS) models. Methods : Colitis was induced by DSS in Balb/c mice. ALE 10, 30, 100 and 300 mg/kg were orally administered twice a day for 7 days in DSS model. Mice weight was measured daily. Scoring of clinical findings was measured every other day. Colon length, edema, fecal blood and histological damages were assessed at day 7 in DSS model. In histological analysis, we checked cryptal glands, surface epithelium, submucosa, transmural, stroma and scored degree of inflammatory cell damage by modified histological scoring. We also calculated cytokines concentrations including IFN-${\gamma}$, TNF-${\alpha}$, IL-6, IL-$1{\beta}$, IL-17, IL-23, IL-10 and TGF-${\beta}1$ by Biometric Multiplex Cytokine Profiling method. Results : ALE showed the protective effects on DSS-induced experimental colitis. ALE inhibited shortening of colon length and histological damages of colon does-dependently, but it did not inhibit weight loss. ALE also inhibited IFN-${\gamma}$ and IL-6 expression, and upregulated cytokines (IL-10, TGF-${\beta}1$) related to regulatory T cell differentiation and proliferation. Conclusions : The current results demonstrate the clinical utility of ALE in traditional medicine and indicate the possibility of potent drug development of inflammatory bowel diseases from natural products. Further investigations for exact mechanisms will be needed.

Allergic skin inflammation such as atopic dermatitis (AD) is characterized by edema and infiltration with various inflammatory cells such as mast cells, basophils, eosinophils and T cells. Thymic stromal lymphopoietin (TSLP) is produced mainly by epidermal keratinocytes, as well as dermal fibroblasts and mast cells in the skin lesions of AD. Omega-3 polyunsaturated fatty acids in fish oil can reduce inflammation in allergic patients. Fermentation has a tremendous capacity to transform chemical structures. The antiinflammatory effects of fish oil have been described in many diseases, but the beneficial effects by which fermented olive flounder oil (FOF) modulates the allergic response is poorly understood. In this study, we produced FOF and tested its ability to suppress the various allergic inflammatory responses. The ability of FOF to modulate the immune system was investigated using a mouse model of AD. The FOF-treated group showed significantly decreased immunoglobulin E (IgE) and histamine in serum. Also, the increased TSLP expression was significantly inhibited in the FOF group; the FOF-treated group was not appreciably different from the hydrocort cream treatment group. In addition, FOF treatment resulted in a smaller spleen size with reduced the thickness and length compared to the induction group. Splenocytes from mice treated with FOF produced significantly less IFN-${\gamma}$, IL-4, T-box transcription factor (T-bet) and GATA binding protein 3 (GATA3) expression compared with the induction group. These results suggest that FOF may be effective in treating the allergic symptoms of AD. 5.

The effects of intraduodenal administration of Clostridium perfringens type D whole culture in goats were evaluated to develop a reliable experimental model of enterotoxemia in this species and the eventual evaluation of treatment with different drug preparations was also carried out. A total of 28 conventionally reared healthy unvaccinated black bangle goat kids of 6-12 months of age were dosed intraduodenally with whole cultures of C peliringens type D. Four kids were used as controls and received sterile, nontoxic culture medium intraduodenally. All animals received starch solution into the abomasum. The clinical signs developed within 12 hours of post inoculation that were similar to those observed in naturally occurring cases. Among the clinical signs, diarrhea was most common (96.43%) followed by dyspnea (53.57%) and central nervous system (CNS) signs (25.0%). The most striking postmortem findings consisted of necrotizing pseudomembranous colitis (100.0%), lung edema (69.23%) and fluid filled intestines (61.53%). The protocol thus provided a reasonable model of naturally occurring enterotoxemia in goats, producing a range of clinical signs and postmortem changes similar to those observed in the natural disease. Beside this, treatment trial with different drug preparations showed penicillin combined with antitoxin was most effective (100.0%), followed by combination of oxytetracyclin with antitoxin, and combined preparation of antitoxin and sulfur drugs both showed 75% recovery rate. On the other hand, treatment with antitoxin, penicillin and oxytetracycline singly could protect goat enterotoxaemia only 25.0%, 50.0% and 50.0%, respectively. Thus in the present study, it eas observed that antisera in combination of antibiotics gave better recovery rate than the antitoxin or antibiotics alone.
