Atopic dermatitis induced NC/Nga mice were used to investigate the efficacy of BDH(Baedokhwan) on the recovery of dermatitic symptoms through its influence on the immune related factors and histological changes. First of all, BDH treated group showed improvement of atopic dermatitis with naked eye observation, and significant decrease of clinical index(CI) was observed after 14 weeks. And Infiltration of leukocytes was suppressed in BDH treated group, and the thickness of hypertrophied epidermis and dermis were decreased. In dorsal skin, BDH treated group showed significant decrease of the ratio of CD3+, CD11b+/Gr-1+ immune cells by 52.8%, 25.2, respectively. And also significant decrease the level of IL-5 mRNA and IL-13 mRNA by 44.4%, 28.0, respectively. In PBMC and serum, BDH treated group showed an decrease of CD4+/CD45+, B220+/CD23+, CD4+, CD8+, CD4+/CD25+ immune cells by 35.0%, 12.6%, 42.7%, 31.6% and 55.6%, respectively, and the level of histamine was decreased by 39.0%. The results above indicated that BDH clinically used for atopic dermatitis treatment has objective validity, and therefore can be provided as the basic data for anti-allergic and anti-inflammatory studies.

Objectives : The purpose of this study was to analyze the effects of Erythrinae Cortex herbal-acupuncture solution(EC-HAS) at the Joksamni($ST_{36}$) of mice with collagen II-induced arthritis(CIA). Methods : The author performed several experimental procedures to observe the effects of the EC-HAS at the arthritis. The severity of arthritis, changes of cytokine level and antibody level, histological changes of the CIA mouse joint were analyzed. Results : 1. The incidence of arthritis and arthritis index were significantly decreased in the cases which were treated with the EC-HA. 2. Cartilage destruction and synovial cell proliferation were reduced, and the expression of the collagen fibers was similar with that of the normal group. 3. The levels of IL-6, $IFN-{\gamma}$, $TNF-{\alpha}$, $IL-1{\beta}$ in serum of the CIA mice which were treated with the EC-HA were significantly decreased compared with those of the normal group. 4. The levels of IgG, IgM and anti-collagen II in serum of CIA mice when they treated with the EC-HA were significantly decreased compared with those of the normal group. 5. The expression ratio of $CD4^+$ to $CD8^+$ cells in the EC-HA treated mice were maintained as much as the normal group of the lymph nodes in the CIA mice. 6. The $CD3e^+CD69^+$ and $CD11b^+Gr-1^+$ cell populations in the knee joint were significantly decreased in the EC-HA treated group. Conclusions : These results suggest that the EC-HA at the ST36 may be responsible roles to control on the synovial cell proliferation and to prevent the cartilage destruction in rheumatoid arthritis. These results will be important supporting evidence for the practical use of the EC-HA at rheumatoid arthritis clinic in the future.

We describe the gene expression profile of third leaves of rice (cv. Nipponbare) seedlings subjected to salt stress (130 mM NaCl). Transcripts of Mn-SOD, Cu/Zn-SOD, cytosolic and stromal APX, GR and CatB were up-regulated, whereas expression of thylakoid-bound APX and CatA were down-regulated. The levels of the compatible solute proline and of transcripts of its biosynthetic gene, ${\Delta}^1$-pyrroline-5-carboxylate synthetase (P5CS), were strongly increased by salt stress. Interestingly, a potential compatible solute, ${\gamma}$-aminobutyric acid (GABA), was also found to be strongly induced by salt stress along with marked up-regulation of transcripts of GABA-transaminase. A dye-swap rice DNA microarray analysis identified a large number of genes whose expression in third leaves was altered by salt stress. Among 149 genes whose expression was altered at all the times assayed (3, 4 and 6 days) during salt stress, there were 47 annotated novel genes and 76 unknown genes. These results provide new insight into the effect of salt stress on the expression of genes related to antioxidant enzymes, proline and GABA as well as of genes in several functional categories.

The assemblage epidote and grandite garnet occurs in low-to medium-grade metabasites and calc schists of various geotectonic settings and in hydrothermally altered calcareous rocks in skarn deposits. The compositions of sixteen epidote-garnet paris have been analysed by means of electron microprobe. Al-Fe partitioning between coexisting grandite garnet and epidote is considered and measured at the grain boundaries on the supposition that the surface equilibrium was maintained in the following exchange reaction: 2$Ca_2Al_3Si_3O_12$(OH)+$Ca_3Fe_2Si_3O_12$=2$Ca_2A_l2FeSi_3O_12$(OH)+$Ca_3Al_2Si_3O_12$ Partition coefficients confirms the differences in thermal conditions between low-grade and medium-grade metamorphic rocks. $K_D$ values ($X_{$CO_2$}$=($Fe^{+3}$/Al)$^{Ep}$/($Fe^{+3}$/Al)$^{Gr}$, where Fe=$Fe^{+3}$) from greenschist facies rocks of the estimated metamorphic temperatures, 330~$390^{\circ}C$, range approximately between 0.02 and 0.17. Epidote-amphibolite facies rocks and calcareous skarns of the estimated temperatures, 400~$550^{\circ}C$, have $K_D$ values between 0.24 and 0.37. $K_D$ values from the rocks of the temperatures, 640~$700^{\circ}C$, range nearly between 0.58 and 0.75. The diagrams in Figs. 2 and 3 can serve as a mineralogic thermometer for relatively shallow rocks, assuming that the pressure dependence of partition coefficients for the iron-exchange reaction in the two minerals can be neglected.

Seed priming leading to improved emergences, germination speed and uniformity under unfavorable conditions without loss of longevity are the best level of techniques. We studied the possibility to obtain primed seed with reduced mean germination time (MGT) and uniformity but with simple, fast and effective methods. The experiments were carried out at $15^{\circ}C$ for 16 hours with priming treatment. To compare the effects of each treatment, we used 200mM $CaCl_2$ priming or hydro priming or no imbibition after ultrasonication or red light treatment. The light treatment was performed by irradiating 2000 lux of red light for 15, 30, 60, and 120 minutes. Addition, in order to investigate the effect of the priming solution, treated at 200mM $CaCl_2$ for 8 hours. Ultrasonication treatment was performed for 5, 10, and 20 minutes at exposures of 13.0, 17.3, and 21.6 kHz during priming. For liquid smoke (LS) treatment, seed soaked in 0%, 0.5%, 1.0%, 5.0% and 10.0% of diluted water and 200mM $CaCl_2$ solution. After each treatment, the seeds were dried to moisture content ranged 5-8% at $25^{\circ}C$ for 24 hours. The effect of seed treatment was evaluated with germination percentage (GP), MGT, germination index(GI), germination rate(GR), Germination Uniformity(GU) and heath seed percentage(HS). For several factors tested, we found that the desired germination improvement could be obtained by treating the seed with ultrasonication at 17.3 kHz for 5 minutes in water or red light exposure at 2000 lux for 120 min in water that resulted very similar to those used to 200mM $CaCl_2$ priming for 16 hrs. However, LS treatment showed no improvement in all diluted solution. Therefore, the methods applied ultrasonication and red light treatment showed high potential for fast and easy treatment avoiding pollution of salt solution waste.

The performance of naked neck and normal chicken was evaluated with respect to growth, carcass, immune, biochemical and stress parameters under winter and summer seasons to assess the suitability of naked neck birds under high temperatures in the global scenario of climate change. The growth performance was significantly ($p{\leq}0.05$) higher in naked neck chicken in the summer season. The dressing percentage was significantly ($p{\leq}0.05$) higher in naked neck birds in both winter and summer season because of reduced plumage. The thigh, giblet and feather proportion significantly ($p{\leq}0.05$) varied between naked neck and normal chickens in summer season. The humeral immune response to sheep red blood cells (SRBC), Newcastle disease vaccine (NDV) and cutaneous basophil hypersensitivity (CBH) did not show any significant differences among the chicken groups. The protein and cholesterol concentration observed was within the normal ranges. The total cholesterol levels in plasma were significantly ($p{\leq}0.05$) lower in naked neck birds in both the seasons. H:L ratio was significantly ($p{\leq}0.05$) lower in summer season indicating less stress in naked neck chicken. Basophil and eosinophil concentration was significantly ($p{\leq}0.05$) higher in normal chicken in summer. The lipid peroxidation was higher in full feathered birds under summer stress. The enzyme glutathione reductase (GR) levels were significantly higher during the summer and varied significantly ($p{\leq}0.05$) between the normal and naked neck chicken in both seasons. The results indicated that the naked neck birds performed significantly better at high ambient temperatures with respect to growth, carcass and biochemical parameters. It was concluded that the ability of the naked neck chicken to adapt to high temperatures foresees a viable option for the biological mitigation of climate change.

This study was carried out to know the effects of Gwanjul9-bang (hereinafter reffered to GJ9) on the inhibition of arthritis induced by collagen on DBA/1J mouse. For this purpose, GJ9 was orally administered to mouse with arthritis induced by collagen II. Cytotoxicity, hepatotoxicity, arthritis index, value of immunocyte in draining lymph node and paw joint, rheumatoid factor (IgG, IgM) in serum were measured in vivo. The cytotoxicity against hFCs was not measured in any concentration. The hepatotoxicity was low in GJ9 treated group compared with MTX group. The arthritis index was decreased significantly. In total cell counts of DLN and paw joint, the cells in DLN increased significantly while there was significantly decrease in paw joint. In lymph nodes, $CD19^+$, $CD3^+$, $CD4^+$, $CD3^+CD69^+$, $CD8^+$, $CD4^+CD25^+$, $CD3^+CD49b^+$, $CD4^+CD44^+$, $CD3^+CD8^+$ cells increased significantly, $B220^+CD23^+$cells decreased significantly. In joints, $CD3^+$, $CD4^+$, $CD4^+CD25^+$, $CD11b^+Gr-1^+$ cells decreased significantly. The levels of IgG and IgM was significantly decreased compared with control. Anti-collagen II in serum was significantly decreased compared with control. The degree of arthritis induced damage of joint of GJ9 group is slight compared with control group in histopathologic observation (Hematoxylin & Eosin, Masson's Trichrome). Comparison of the results for this study showed that GJ9 had immunomodulatory effects. So we expect that GJ9 should be used as a effective drugs for not only rheumatoid arthritis but also another auto-immune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

Purpose: This study provides comparative measurements of absorbed and effective doses for newly developed cone beam computed tomography (CT) in comparison with these doses for conventional CT. Materials and Methods: Thermoluminescent dosimeter rods (TLD rod: GR-200, Thermo Fisher Scientific Inc., Waltham, MA, USA) were placed at 25 sites throughout the layers of Male ART Head and Neck Phantom (Radiology Support Devices Inc., Long Beach, USA) for dosimetry. Implagraphy, DCT Pro (Vatech Co., Hwasung, Korea) units, SCT-6800TXL (Shimadzu Corp., Kyoto, Japan), and Crane x 3+(Soredex Orion Corp., Helsinki, Finland) were used for radiation exposures. Absorption doses were measured with Harshaw 3500TLD reader (Thermo Fisher Scientific Inc., Waltham, MA, USA). Radiation weighted doses and effective doses were measured and calculated by 2005 ICRP tissue weighting factors. Results: Absorbed doses in Rt. submandibular gland were 110.57 mGy for SCT 6800TXL (Implant), 24.56 mGy for SCT 6800TXL (3D), 22.39 mGy for Implagraphy 3, 7.19 mGy for DCT Pro, 5.96 mGy for Implagraphy 1, 0.70 mGy for Cranex 3+. Effective doses $(E_{2005draft)$ were 2.551 mSv for SCT 6800TXL (Implant), 1.272 mSv for SCT 6800TXL (3D), 0.598 mSv for Implagraphy 3, 0.428 mSv for DCT Pro and 0.146 mSv for Implagraphy 1. These are 108.6, 54.1, 25.5, 18.2 and 6.2 times greater than panoramic examination (Cranex 3+) doses (0.023mSv). Conclusion: Cone beam CT machines recently developed in Korea, showed lower effective doses than conventional CT. Cone beam CT provides a lower dose and cost alternative to conventional CT, promising to revolutionize the practice of oral and maxillofacial radiology.
