  • Background: Myofascial pain dysfunction syndrome (MPDS), otherwise called myofascial pain is one of the most common temporomandibular disorders, which in turn is the most common cause of orofacial pain of non-dental origin. Its etiology is multifactorial and still poorly understood. Psychological factors have been shown to play a role in the etiology. The aim of the study was to evaluate the association between anxiety and salivary cortisol levels in patients with myofascial pain. Methods: Twenty patients suffering from myofascial pain were recruited as the study group. The same number of age and sex matched healthy individuals were taken as the control group. The salivary samples collected between 9-9:15 am from both groups were analyzed for cortisol levels with the competitive enzyme-linked immunosorbent assay method. Anxiety levels of 40 patients were measured using Hamilton's anxiety scale. Results: The mean serum cortisol level of the MPDS group showed a highly significant difference (P < 0.001) from the controls. The mean anxiety scores of the MPDS group showed a highly significant difference (P < 0.001) from the controls. A positive correlation was found between anxiety and the salivary cortisol levels in MPDS patients. Conclusions: These findings suggest that anxiety plays a vital role in the etio-pathogenesis of MPDS; thus, besides pharmacological treatment, psychological support is also needed.

  • In this study, hybridoma techniques were applied to produce monoclonal antobodies to Paragonimus westermani, commonly known as lung distoma. Balb/c mice were immunized intraperitoneally every week with increasing doses of purfied protein of Paragonimus westermani adult worms begining with 0.3/mg/mouse/7 days and ending with 0.5mg at 28th day. Spleen cells from these immunized mice were hybridized with myeloma cells (NS-1) and the hybridized cells were selected in HAT media. The antibody secreting cells among the hybrid cells were initially selected by ELISA. Those initially selected cells were further screened by the criteria of antibody producing activity, and seneral cell lines among them were further tested with immunodiffusion method. One hybridoma clone produced IgM and another clone produced IgG1. The supernatant of the hybridoma clone producing IgM had titer 1:64 and the hybridoma clone producing IgG1 had titer 1:256 measured by immunofluorescence technique.

  • This study was carried out to evaluate the application of food irradiation technology as a method for reducing milk allergies. Bovine $\alpha$-casein, $\beta$-casein, $textsc{k}$-casein, $\alpha$-lactalbumin(ALA), $\beta$-lactoglobulin (BLG) and serum albumin (BSA) were used as model allergens of milk proteins and the proten solution (2.0 mg/mL) with 0.01 M phosphate buffered saline (pH 7.4) was irradiated at 3, 5 and 10 kGy. Using milk-hypersensitive patients IgE (MHP-IgE), the changes of binding ability to irradiated proteins were observed by competitive indirect enzyme-linked immunosorbent assay (Ci-ELISA). Affinity of MHP-IgE to milk proteins was higher in ALA and BLG than that of other proteins. Standard curve to each non-irradiated protein could be made with MHP-IgE for quantifying milk allergens. Binding abilities of MHP-IgE to the irradiated proteins, however, decreased with different slopes of the standard curves. Sensitivity of gamma irradiation was higher in ALA and BLG than of other proteins. These results indicated that irradiation technology can be used to reduce the milk hypersensitivity.

  • Grapevine leafroll-associated virus 3(GLRaV-3) is one of the most severe pathogens for viral diseases found in Korea. This study was conducted to establish the virus-free stock production system for the virus disease control. The effects of thermotherapy, merestem culture and chemotheratpy to eliminate the GLRaV-3 in gratevines were tested. Thermotherapy at 37$\pm$2$^{\circ}C$ for 6∼8 weeks combined with 0.5∼1.0mm size of meristem culture method was the most effective for virus elimination. Thermotherapy alone was not effective. In chemotheratpy, DHT and Amantadine (20, 40mg/L) treatment in medium was more effective than Ribavirin to eliminate the GLRaV-3 in grapevine. However, Ribavirin spraying to potted was not available for virus elimination. Therefore, virus-free stock production system using the thermotherapy combined with shoot apical meristem culture was the most effective in grapevine.

  • It has been established that a graft of fibroblasts is able to improve wound healing. However, there has been no research on the effect of a graft of bone marrow stromal cells on wound healing. The wound healing process requires cell proliferation and production of extracellular matrix and various growth factors. The purpose of this study was to compare the abilities of human fibroblasts and bone marrow stromal cells, which contains mesenchymal stem cells, to proliferate and to produce collagen. Human bone marrow stromal cells and fibroblasts were isolated from bone marrow and dermis of the same patients and grown in culture respectively. Cell proliferation and production of type I collagen by human bone marrow stromal cells and dermal fibroblasts were examined by MTT method and by ELISA of cell culture media on day 1, 3, and 5 days post-incubating. The human bone marrow stromal cells showed 11-17% higher cell proliferation than fibroblasts at each time interval. The levels of type I collagen in the human bone marrow stromal cell group was also significantly higher than those in the fibroblast group. The results indicate that the grafts of human bone marrow stromal cells can show more promising effect than that of fibroblasts for healing of chronic wounds.

  • In this study, we investigated the kinetics of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and high mobility group box 1 (HMGB1) concentrations in a 48-h model of canine endotoxemia by lipopolysaccharide (LPS) injection. Four healthy beagles were slowly administered 1 mg/kg of LPS diluted in normal saline, while two others were administered normal saline as controls. Blood collection was performed at 0 h (baseline), 1 h and 3 h (for TNF-${\alpha}$), 6 h, 12 h, 24 h and 48 h of the experiment, and cytokine levels were determined using the sandwich ELISA method. Early increments of TNF-${\alpha}$ and IL-6 were observed (< 3 h), but HMGB1 levels increased the most at 12 h of the experiment and gradually decreased until 48 h. During the whole experiment, IL-6 and HMGB1 were sustained over 12 h of LPS injection, whereas TNF-${\alpha}$ decreased within 6 h of LPS injection. Taken together, canine HMGB1 levels increase relatively late (< 12 h) and sustained longer than TNF-${\alpha}$ and IL-6 in response to endotoxin. This is the first study to evaluate canine HMGB1 cytokine from endotoxemia in dogs.
