Objectives: This study is designed to verify the effects of Mannyeon-hwan (MNH) on acetic acid-induced colitis in rats. Methods: Colitis was induced in male Sprague-Dawley rats weighing approximately 250 g by injecting acetic acid through the anus. The rats were classified into four groups: normal group, acetic acid (AA) group, AA+MNH (L) (low concentration) group, and AA+MNH (H) (high concentration) group. The body weight, visual evaluation of the colonic mucosa, anatomical histological changes, and changes in the expression of cytokines in the colon tissue were compared and analyzed. Results: Compared with the normal group, weight loss was observed in mice induced with colitis. Compared with the AA group, weight loss recovery occurred in the AA+MNH (L) and AA+MNH (H) groups, and significant changes were observed after the sixth day. In the visual evaluation of the colonic mucosa, a significant decrease in damage indicators was observed in the AA+MNH (L) and AA+MNH (H) groups compared with the AA group. In terms of anatomical histological changes and changes in the expression of tumor necrosis factor-α and interleukin-6 in colon tissue, a significant decrease was observed in the AA+MNH (L) and AA+MNH (H) groups compared with the AA group. A more pronounced decrease was observed in the AA+MNH (H) group compared with the AA+MNH (L) group. Conclusion: The effects of MNH on colitis were confirmed through research. MNH can be used as a first-line treatment for patients complaining of colitis who visit oriental medicine clinics.

The anti-inflammatory activity of SEO-KYONG-TANG extract(SKTWE) was examined by using carrageenin- and acetic acid-induced edema, croton oil-induced granuloma pouch, and adjuvant arthritis in rats. In addition, the acute toxicity, analgesic and antipyretic effects of SKTWE were investigated by using general experimental methods in mice. SKTWE did not show acute toxicity at 2400 mg/kg(p.o.) nor 1200 mg/kg(i.p.). After oral administration of the SKTWE to rats, significant anti-inflammatory activity was observed on 1% carrageenin- and 5% acetic acid-induced edema. Also, it significantly inhibited granuloma and exudation in these. In the adjuvant arthritis experiment, the SKTWE decreased the hind paw edema after 3 days of oral administration. In addition, it inhibited the writhing syndromes induced by 0.7% acetic acid in mice. The antipyretic activity of SKTWE was also observed through the typhoid vaccine experiment. These results suggest that SKTWE has analgesic, anti-inflammatory and antipyretic action.

As an effective non-pharmacological method of pain relief, hydrotherapy was widely used. And bath additive has been used for enhancing the efficacy of hydrotherapy, In the present study, as a bath additive, the analgesic activity of HAC, which composed of Corydalis turtschaninovii, Atractylodes japonica, and Harpagophytum procumbens(HAC), was investigated in the ventrolateral periaqueductal gray (VIPAG), lateral PAG (IPAG), central nuclei of amygdala (CeA), and the paraventricular nucleus of the hypothalamus (PVN) in mice, using writhing test and immunohistochemistry for c-Fos. Male C57BU6 mice weighing $25{\;}{\pm}{\;}2g$ (8 weeks of age) were used for this experiment. The animals were divided into five groups: the control group, the acetic acid treatment group, the acetic acid treatment and 0.01 g/L HAC-immersed group, the acetic acid treatment and 0.1 g/L HAC-immersed group, and the acetic acid treatment and 1.0 g/L HAC-immersed group. To induce somato-visceral pain in the experimental animals, a single intraperitoneal (i.p.) injection of acetic acid was administrated to each animal, and the animals of the control group received injections of equivalent doses of normal saline. The animals of the HAC-immersed groups were immersed the water with HAC powder at the respective doses deep enough to cover the mice body, and those of the control group and the acetic acid treatment group immersed the water without HAC powder at 10 min immediately after the acetic acid injection. Our present study has shown that the HAC reduced the acetic acid-induced abdominal constrictions and the acetic acid-Induced increase of numbers of c-Fos-positive cells in the VIPAG, IPAG, PVN, and CeA. The most potent analgesic effect appeared with the treatment of 1.0 g/L KB-immersed group. Based on our present results, it is very possible that HAC can be a potent therapeutic bath additive for alleviating pain without the fear of addiction to the drugs and side-effects associated with the prescription of multiple analgesic drugs.

Objectives : This study was purposed to investigate the Anti-inflammatory and Analgesic Effects of Gold injection Aqua-acupuncture on the experimental model of rheumatoid arthritis. Methods : The experimental groups were divided into 4 groups : Control group (group injected with normal saline), J-NS (group injected with normal saline into bilateral Choksamni(ST36)), J-GS (group injected with Gold Injection into bilateral Choksamni(ST36)), and N-GS (injected with Gold Injection into the blank locus of the root of mouse tail). In addition, Diclofenac-Na as a comparative medicine is injected into bilateral Choksamni(ST36) and the blank locus of the root of mouse tail. So we measured the mice paw edema induced by Carrageenin and Dextran, the chronic rat paw edema induced by adjuvant, vascular permeability induced by Acetic acid in mice, the writhing syndrome induced by Acetic acid in mice, the heat-induced pain threshold in mice. Results : The following result have been obtained. 1. The mice paw edema induced by Carrageenin was significantly decreased in J-GS as compared with the control group. 2. The mice paw edema induced by Dextran was significantly decreased in J-GS and N-GS as compared with the control group. 3. The chronic rat paw edema induced by Adjuvant was significantly decreased in J-GS and N-GS as compared with the control group. Serum Iron content was significantly decreased in J-GS and N-GS as compared with the control group. But the effect on the Serum Copper contents has no significance statistically. 4. Vascular permeability induced by Acetic acid in mice was significantly decreased in J-GS and N-GS as compared with the control group. 5. The level of Acetic acid-induced Writhing syndrome and Heat-induced Pain Threshold in mice were all significantly decreased in J-GS and N-GS as compared with the control group. Conclusion : According to the result, gold injection aqua-acupuncture has significant anti-inflammatory and analgesic effects on the experimental model of rheumatiod arthiritis.

The antiinflammatory and analgesic activities of higenamine were evaluated by measuring edema volume and pain threshold in adjuvant arthritic rats and acetic acid-induced writhing test in mice. Higenamine, with consecutive oral administrations at doses of 10 and 50 mg/kg/day, showed significant antiedemic effect and elevation of pain threshold during the secondary lesion of adjuvant arthritis. Higenamine also showed a significant inhibition of acetic acid-induced writhing syndrome with a single oral administration (200 mg/kg). From these results, it is postulated that higenamine might possess both of centrally and peripherally mediated analgesic properties.

In the previous study, we reported that the in viかo inhibitory effect of ginsenosides, active ingredient of Panax ginseng, on $5-HT_{3A}$ receptor channel activity is coupled to in vivo anti-vomiting and anti-nausea effect. In the present study, we further investigated that the inhibitory effect of ginsenosides, active ingredient of Panax ginseng, on 5-HT3A receptor channel activity is also coupled to attenuation of irritable bowel syndrome (IBS), which is induced by colorectal distention (CRD) and $0.6\%$ acetic acid treatment. The CRD-induced visceral pains induced by CRD and acetic acid treatment are measured by frequency of contractions of the external oblique muscle in conscious rats. Treatment of GTS significantly inhibited CRD-induced visceral pain with dose-dependent manner. The $EC_{50}$ was $5.5{\pm}4.7$ mg/kg ($95\%$ confidence intervals: 1.2-15.7) and the antinociceptive effect of GTS on visceral pain was persistent for 4 h. We also compared the effects of protopanaxadiol (PD) ginsenosides and protopanaxatriol (PT) ginsenosides with saline on acetic acid-and CRD-induced visceral pain, and found that protopanaxatriol (PT) ginsenosides was much more potent than PD ginsenosides in attenuating CRD-induced visceral pain. These results indicate that U ginsenosides of Panax ginseng are components far attenuation of experimentally CRD-induced visceral pains.
