This study examined the efficacy of Atractylodes macrocephala Koidz (AMK) protein and polysaccharide extracts as adjuvant or adjuvant booster when given together with porcine pleuropneumonia vaccine. Experimental mice (n = 5/group) were subcutaneously immunized with $25{\mu}g$ ApxIIA #3 antigen, a target protein against A. pleuropneumoniae, together with alum and/or various concentrations ($0-500{\mu}g$) of the AMK extracts, while the control group received PBS only. Immunization with ApxIIA #3 antigen increased the antigen-specific IgG titer and this increase was enhanced in the immunization together with AMK protein, but not polysaccharide extract. Supplementation of AMK protein extract exhibited dose-dependent increases in the antigen-induced protective immunity against A. pleuropneumoniae challenge and in the lymphocyte proliferation specific to the antigen. Glycoproteins present in the AMK extract were the active components responsible for immune response induction. Collectively, the present findings suggest that AMK glycoproteins are useful as immune stimulating adjuvant or adjuvant booster.

Odontogenic keratocysts (OKCs) located in the maxillae have rarely been reported in the literature. Standard treatment modalities for OKC range from marsupialization to marginal resection. However, most of the studies on OKC treatment have been related to mandibular OKCs. The anatomical structure and loose bone density of the maxillae and the empty space of the maxillary sinus could allow rapid growth of a lesion and the ability to tolerate tumor occupancy in the entire maxilla within a short period of time. Therefore, OKCs of the maxillae require more aggressive surgery, suchas resection. As an alternative, this report introduces a modified Carnoy's solution, a strong acid, as an adjuvant chemotherapy after cyst enucleation. This report describes the clinical outcomes of enucleation using a modified Carnoy's solution in patients with large OKCs on the posterior maxillae. In three cases, application of a modified Carnoy's solution had few side effects or morbidity. Each patient was followed for four to six years, and none showed any signs of recurrence. In conclusion, adjuvant treatment with a modified Carnoy's solution can be considered a treatment option capable of reducing the recurrence rate of OKC in the maxillae.

We investigated the role of the central MAPK pathways in extra-territorial (referred) pain resulting from inflammation of the temporomandibular joint (TMJ). Experiments were carried out on male Sprague-Dawley rats weighing 220-280 g. Under anesthesia, these animals were injected with $50\;{\mu}L$ of complete Freund's adjuvant (CFA) into the TMJ using a Hamilton syringe. In the control group, saline was injected into the TMJ. To identify the extent of inflammation of the TMJ, Evans blue dye (0.1%, 5 mg/kg) was injected intravenously at 1, 3, 6, 9, 12 and 15 days after CFA injection. The concentration of Evans blue dye in the extracted TMJ tissue was found to be significantly higher in the CFA-treated animals than in the saline-treated group. Air-puff thresholds in the vibrissa pad area were evaluated 3 days before and at 3, 6, 9, 12, 15 and 18 days after CFA injection into the TMJ. Referred mechanical allodynia was established at 3 days, remained until 12 days, and recovered to preoperative levels at 18 days after CFA injection. This referred mechanical allodynia was observed in contralateral side area. To investigate the role of central MAPK pathways, MAPK inhibitors ($10\;{\mu}g$) were administrated intracisternally 9 days after CFA injection. SB203580, a p38 MAPK inhibitor, significantly attenuated referred mechanical allodynia, as compared with the vehicle group. PD98059, a MEK inhibitor, also reduced CFA-induced referred mechanical allodynia. These results suggest that TMJ inflammation produces extra-territorial mechanical allodynia, and that this is mediated by central MAPK pathways.

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.

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.

Vaccine is one of the best known and most successful applications of immunological theory to human health and it protects human life through inducing the immune response in systemic compartment. However, when we consider the fact that mucosal epithelium is exposed to diverse foreign materials including viruses, bacteria, and food antigens and protects body from entry of unwanted materials using layer of tightly joined epithelial cells, establishing the immunological barrier on the lining of mucosal surfaces is believed to be an effective strategy to protect body from unwanted antigens. Unfortunately, however, oral mucosal site, which is considered as the best target to induce mucosal immune response due to application convenience, is prone to induce immune tolerance rather than immune stimulation. Since intestinal epithelium is tightly organized, a prerequisite for successful mucosal vaccination is delivery of antigen to mucosal immune induction site including a complex system of highly specialized cells such as M cells. Consequently, development of efficient mucosal adjuvant capable of introducing antigens to mucosal immune induction site and overcome oral tolerance is an important subject in oral vaccine development. In this review, various approaches on the development of oral mucosal adjuvants being suggested for effective oral mucosal immune induction.

Background: There have been several reports describing the capability of ginseng extracts as an adjuvant. In this study, we tested if ginsan, a polysaccharide extracted from Panax ginseng, was effective in enhancing antibody response to orally delivered Salmonella antigen. Methods: Ginsan was treated before oral salmonella antigen administration. Salmonella specific antibody was determined by ELISA. mRNA expression was determined by RT-PCR. Cell migration was determined by confocal microscopy and flow cytometry. COX expression was detected by western blot. Results: Ginsan treatment before oral Salmonella antigen delivery significantly increased both secretory and serum antibody production. Ginsan increased the expression of COX in the Peyer's patches. Various genes were screened and we found that CCL3 mRNA expression was increased in the Peyer's patch. Ginsan increased dendritic cells in the Peyer's patch and newly migrated dendritic cells were mostly found in the subepithelial dome region. When COX inhibitors were treated, the expression of CCL3 was reduced. COX inhibitor also antagonized both the migration of dendritic cells and the humoral immune response against oral Salmonella antigen. Conclusion: Ginsan effectively enhances the humoral immune response to orally delivered antigen, mediated by CCL3 via COX. Ginsan may serve as a potent vaccine suppliment for oral immunization.

Ohyaksungisan, combined preparation of crude drugs, has been used for hemiplegia, arthralgia and paralysis in traditional Korean medicine. The anti-inflammatory activity of the aqueous extract from Ohyaksungisan(OSSE) was investigated on acetic acid-induced edema and adjuvant arthritis in rats. Acute toxicity and analgesic action in mice were also examined. Its anti-inflammatory activity on 5% acetic acid-induced edema and adjuvant arthritis was observed with oral administration. The acute toxicity showed 10% mortality at 2400 mg/kg (p.o), but was not showed at 1200 mg/kg (i.p). OSSE was showed to have significant analgesic action (P<0.05) at 150 mg/kg and this action was strengthened at 300, 600 mg/kg. The anti-inflammatory effect was showed significant preventive effect on the hind paw edema from 90 min. and the adjuvant arthritis, when orally administered for 19 days. showed significant inhibitory effect on the hind paw edema from the 5th day.

These studies were conducted to investigate the antiinflammatory effects and the mechanism of action of natural products. We used the methods of "carrageenan induced foot edema" , "PAF (platelet activating factor) induced foot edema" , "inhibition test of vascular permeability" , "inhibition test of white blood cell migration" , "formation of granuloma" and "adjuvant induced arthritis" to examine the antiinflammatory erects of Angelica gigas, Ledebouriella seseloides, Ginkgo biloba and Bamboo salt (Jukyom). The oral administration of the water extract of Angelica gigantis radix, the methanolic extract of Ginkgo folium and the aqueous solution of Bamboo salt showed antiinflammatory effect on carrageenan and PAF induced foot edema in SD rat at a dose of 1 g/kg. The same administration of methanolic extract of Ginkgo folium also inhibited the vascular permeability in mice. The aqueous solution of Bamboo salt inhibited the formation of ganuloma in SD rats at a oral dose of 1 g/kg. Angelica gigantis radix seems to have antiinflammatory effect by inhibition of PAF.

Purpose: There is sparse literature on treatment outcomes research on resectable oral tongue squamous cell carcinoma (OTSCC). The aim of this study was to measure the treatment outcomes, explore the failure patterns, and identify the potential clinicopathological prognostic factors affecting treatment outcomes for resectable OTSCC. Materials and Methods: It is a retrospective analysis of 202 patients with resectable OTSCC who underwent upfront primary surgical resection followed by adjuvant radiotherapy with or without concurrent chemotherapy if indicated. Results: The median follow-up was 35.2 months (range, 1.2 to 99.9 months). The median duration of locoregional control (LRC) was 84.9 months (95% confidence interval, 67.3-102.4). The 3- and 5-year LRC rate was 68.5% and 58.3%, respectively. Multivariate analysis showed that increasing pT stage, increasing pN stage, and the presence of extracapsular extension (ECE) were significantly associated with poorer LRC. The median duration of overall survival (OS) was not reached at the time of analysis. The 3- and 5-year OS rate was 70.5% and 66.6%, respectively. Multivariate analysis showed that increasing pT stage and the presence of ECE were significantly associated with a poorer OS. Conclusion: Locoregional failure remains the main cause of treatment failure in resectable OTSCC. There is scope to further improve prognosis considering modest LRC and OS. Pathological T-stage, N-stage, and ECE are strong prognostic factors. Further research is required to confirm whether adjuvant therapy adds to treatment outcomes in cases with lymphovascular invasion, perineural invasion, and depth of invasion, and help clinicians tailoring adjuvant therapy.
