Dojuk-San is known to be effective for treating a urinary diseases and stomatitis. However, its effects on the bone marrow-derived mast cell(BMMC) mediated allergy and inflammation mechanism remain unknown. In this study, the biological effects of Dojuk-San ethanol extract(DJS) were evaluated while focusing on its effects on the allergic mediator in phorbol 12-myristate 13-acetate(PMA) plus calcium ionophore A23187(A23187)-stimulated BMMCs. An investigation was also conducted to determine its effects on the production of several allergic mediators including interleukin-6(IL-6), prostaglandin D2($PGD_2$), leukotrieneC4(LTC4) and ${\beta}$-Hexosaminidase(${\beta}$-Hex). The results revealed that DJS inhibited the PMA plus A23187 induced production of IL-6, PGD2, LTC4 and ${\beta}$-Hex. Taken together, these findings indicate that DJS has the potential using in the treatment of allergy.

We studied to know the anti-inflammation effect on water extracts of Lophatheri Herba which was growing in every places in our country. We objected free radical scanvenger effect and nitrite eliminate effect of the Lophatheri Herba water extracts, and the cell viabillity, the effects of Lophatheri Herba water extracts on NO production, iNOS synthesis induced by LPS. Free radical scavenger effects were $27.91{\pm}0.12%$, $38.96{\pm}0.10%$, $46.22{\pm}0.15%$ depend on 0.5, 1.0, 2.0 mg/ml each dose of Lophatheri Herba water extracts. Nitrite eliminate effects were $9.86{\pm}0.3%$, $80.61{\pm}0.23%$, $97.62{\pm}0.56%$ in 0.1, 1.0, 2.0 mg/ml Lophatheri Herba water extracts on pH 1.2. NO production and iNOS synthesis induced by LPS were reduced in RAW 264.7 cell by Lophatheri Herba water extracts. As the above results, Lophatheri Herba water extracts have anti-inflammation effects via NO production decrease, iNOS synthesis decrease mechanism. So Lophatheri Herba water extracts will be used as the protection or treatment in chronic inflammation desease like a asthma, stomatitis etc.

There are several oral lesions related with AIDS, such as candidiasis, hairy leukoplakia, Kaposi's sarcoma, aphthous stomatitis, lichen planus, and other opportunistic infectious diseases. Among the others, Kaposi's sarcoma, the most common malignant tumor associated with AIDS, is closely linked to the number of CD4+ T cell. Kaposi's sarcoma often occurs in palate, the most prone site, and has characteristic clinical features in most cases. Sometimes, the tumor induces underlying bone destruction at late stage. We report a case of a 27 year-old man with AIDS-associated Kaposi's sarcoma at left lower retromolar triangle, parapharyngeal area and discuss the management of AIDS patients in dentistry.

Purpose : Colonization of denture soft lining materials by Candida albicans can result in clinical problem, and deterioration of the materials. This study aimed to compare the retention and penetration of C. albicans into four denture soft lining materials commonly used. Materials and methods : Four denture soft lining materials (Coe-comfort$^{(R)}$, Coe-soft$^{(R)}$, GC soft liner$^{(R)}$, and Tissue conditioner$^{(R)}$) discs were prepared to glass slide and dental stone. Adherence of yeast to surfaces was monitored after one hour incubation of standardized washed cell suspension with test disc surfaces. Adherent cells stained with acridine orange were counted fluorescence microscopy. Penetration of yeast into materials bonded with acrylic resin after 1, 2, 3,4, 5, 6 and 7 days incubation was observed through sections stained using acridine orange and estimated to quantitative analysis using radioisotope. Results : There was statistical significance in cell numbers between smooth and rough surfaces(p<0.05). Higher numbers of cells were observed on rough surfaces. There was statistical significance in adherent cell numbers into smooth and rough surfaces individually(p<0.05). According to the increase of incubation periods, the cells penetrated into denture soft lining materials were shown to increase. The differences among all kinds of soft liner were statistically significant(p<0.05),and the largest number of cells penetrated into soft liners was observed in the Coe-soft$^{(R)}$. Conclusion : Initial adherence and penetration of yeast into denture soft lining materials has been influenced by surface roughness and chemical composition of them. The selection of appropriate materials and their fabrication may promote clinical performance.

Purpose: This study aimed to evaluate the effectiveness of continuous nutritional education and oral mucositis management on the nutritive status of patients who received hematopoietic stem cell transplantation (HSCT). Methods: After randomly allotting 72 patients who received HSCT to either an experimental group or a control group, intensive and continuous care for preventing malnutrition was conducted in the experimental group while usual routine care was conducted in the control group. The changes of the body scale, blood chemistry profile, oral intake calories, nausea and vomitus, and oral stomatitis scores were measured at three points during their hospitalization using a oral assessment guide and nutrition analysis program: admission, HSCT, and discharge day. The differences between the scores of two groups were analyzed by repeated measures analysis of covariance. Results: The number of total lymphocytes was significantly improved in the experimental group after transplantation (p<.001). Nausea and vomiting score was significantly decreased in the experimental group during the conditioning regimen (p<.001). Conclusion: It was found that continuous nutritional education and oral mucositis control is an effective intervention by improving immune condition. Further investigations concerning direct examination of oral intake with controlling the effect of the chemotherapy are needed to ultimately discern the impact of varying oral nutrition patterns during HSCT.

Syntheses of new analogues of oxathiin carboxanilide (UC84) and their antiviral activities were described. The heterocyclic carboxylic acids including oxathiins (4), thiazines (9) and dithiins (13) in which the methyl was replaced either by lipophilic trifluoromethyl- or bulky phenylgroup were synthesized starting from $\beta$-keto esters (5). Reaction of 4, 9 and 13 with thionyl chloride followed by treatment of the substituted aniline 22 gave the corresponding carboxanilides (24a~24f). The carboxanilides were subjected to Laweson's reagent the corresponding thiocarboxanilides (24g~24k). The antiviral activities of the synthesized compounds against human immunodeficiency virus type 1 (HIV-1), poliovirus type 1 (PV-1 ), coxsackie B virus type 3 (CoxB-3), vesicular stomatitis virus (VSV) and herpes simplex virus type 1 (HSV-1) were presented. The antiviral activity against HIV-1 of dithiin carboxanilide (24e) was similar with that of UC84 (24a). The corresponding thiocarboxanilides (24g~24k) showed higher inhibitory activity against HIV-1 than the carboxanilides (24a, 24b, 24d, 24e). The compounds in which ether the lipophilic trifluorormethyl substituents (24d, 24f, 24i ,24k) or bulky phenyl substituent is present in the heterocyclic compounds showed lower inhibitory activity than that of the methyl substituents is present in the compounds against the HIV-1. But the trifluoromethylated dithiin (24f) showed higher inhibitory activity against PV-1 and CoxB-3 virus than commercial antiviral agents, ribavirin (RV).

Candida albicans is now well recognized among the denture stomatitis patients. The broth macrodilution test is the most widely used technique for antifungal susceptibility testing. The purpose of this study was to determine the C. albicans carrier rate of the denture patients in Iksan, chonbuk. To determine the C. albicans carrier rate of denture patients, culture were made from 227 sample taken in Iksan, Chonbuk during July 1997 to August 1997. Also activities of amphotericin B and miconzole against isolates of denture patients of C. albicans were tested by broth macrodilution test using RPMI medium 1640. The results were as follows : First C. ablicans was isolated from 6.6% of denture patients samples and the frequency of isolation fo C. albicans was highest(50%) in the age group of 71-year-old to 80-year-old denture patients. Second, against C. albicans, the MIC range of amphotericn B was $0.06{\sim}0.25{\mu}g/ml$. MIC50 and MIC90 were $0.13{\mu}g/ml$ and $0.25{\mu}g/ml$, respectively. Third, the MIC range of miconazole was $10-{\ge}20{\mu}g/ml$ and MIC50 and MIC90 were $20{\mu}g/ml$ and ${\ge}20{\mu}g/ml$, respectively. It was concluded from this study that C. albicans acrriages from healthy denture individuals only over 60-year-old ages were isolated, they remain susceptible to amphotericin B and not rarely resistant to miconzole.

Behcet's disease is a complex multisystem disease that features recurrent aphthous stomatitis, recurrent genital ulcerations, and eye lesions(uveitis or chorioretinitis). Among the systemic manifestations, pulmonary involvement is known to be rare and only a few cases have been documented. The most important features of pulmonary lesions in Behcet's disease are recurrent hemoptysis, which is often massive, and fatal pleuritic chest pain and recurrent high fever and fleeting nature of the pulmonary infiltrates. We report a case of Behcet's disease manifestated as high fever and pleural effusions which was complicated by pulmonary infarction as a result of pulmonary arteritis.
