Stress is known to influence the immune function via an effect on the central nervous system. To investigated the effects of Kwibitang water extract (KBT) on the specific immune response in C57BL/6 mice stressed by immobilization, we evaluated the changes in the cell viability, DNA fragmentation and subpopulation of thymocytes and splenocytes. KBT enhanced the cell viability of thymocytes and splenocytes decreased by immobilization stress. Also, KBT decreased DNA fragmentation of thymocytes and splenocytes increased by immobilization stress. KBT decreased the population of CD4/sup +/ cells and CD8/sup +/ cells in thymocytes and Thy1/sup +/ cells in splenocytes increased by immobolization stress, but increased the population of B220/sup +/ cells decreased by immobilization stress. In addition, KBT enhanced the production of ν-interferon and IL-2 decreased by immobilization stress. These results indicate that KBT may be useful for the prevention and treatment of stress via enhancement of the specific immune response

Spatholobus Suberectus dunn. has been applied to blood stasis in oriental medicine. We selected one potent ethyl acetate subfraction-2 from Spatholobus Suberectus Dunn.(SSD) from anti-metastasis screening. It exerted the cytotoxicity against HT1080 and B16BL6 with the IC50 of 60 ug/ml and also significantly inhibited tumor cell induced platelet aggregation (TCIPA). It effectively didn't inhibit cell adhesion of HT1080 to matrigel coated wells, while it inhibited the cell invasion of HT1080 at the doses of 10, 20, 40 μg/ml by Boyden chamber assay. It effectively suppressed lung metastasis by B16BL6 melanoma in C57BL6 mice. These results indicate that the EtOAc subfraction-2 of Spatholobus Suberectus Dunn. can be applied to caner treatment with anti-metastatic activity.

Antimetastatic effects of Agaricus mixed prescription (AMP) were studied in the respect of blood-borne metastasis. For this aim, cytotoxicity against various cancer cells and normal cells, Chicken Chorioallantoic membrane (CAM) assay, cancer cell adhesion assay, platelet aggregation assay, pulmonary colonization, life span of S-180 implanted mice, and cytokine release assay were evaluated, respectively. The results were summarized as follows; AMP did not exert any cytotoxicity against all cell lines with IC50 of 25mg/ml on B16BL6. AMP disrupted formation of CAM at 1mg/ml. AMP was suppressive in adhesion assay of B16BL6. AMP also inhibited tumor induced platelet aggregation. In pulmonary colonization assay by B16BL6, the number of colonies in the lungs was significantly decreased in sample group than in control group. In animal study with S-180, the life span of AMP treated group was extended than that of control group. IL-12 was effectively increased in AMP treated group in cytokine release assay. Taken together, AMP can be possibly applied to cancer or metastasis.

We assessed whether the cow1 mutant defects are associated with growth of Tos17 and T-DNA insertional rice in blue light (BL). Growth of oscow1 mutants which encoded a member of the YUCCA protein family was retarded in BL. Root to shoot ratios of the mutants were reduced about 2 times lower in the absence of NAA and about 2.5 times lower in the presence of NAA; the shoot growth was not significantly changed by NAA addition. Photosynthetic activity of the mutants was however inhibited in high light. Pigment analysis showed significant difference between wild-type (Chl a:b = 3.02) and mutants (3.84). Carotenoid contents of the mutants were also decreased considerably, implying the involvement of cow1 in pigment formation. These findings lead us to suggest that the growth retardation of oscow1 mutant plants by BL results from the difference of photosynthetic activity in part.

Objectives The purpose of this study is to understand effect on respiratory disease and satisfaction of parents about acupoint sticking in hottest period of summer. Methods A survey was conducted to the parents of their children who took acupoint sticking in Dog-days for two years in a row. 17 children (10 boys, 7 girls, 4.0-12.11 years) were attached Socheongo to BL-13, BL-15, BL-17 for 3 hours. In terms of the effectiveness of the therapy, the treatment only considered as effective when there is any improvement in respiratory symptoms. Results 11 children (64.7%) from the study group have shown positive effect. There were significant improvements in frequency of having a cold or duration of a cold; duration of rhinitis; frequency of having empyema or its duration; frequency of having bronchitis; frequency of having pneumonia; frequency of having otitis media. Respiratory health VAS (Visual Analog Scale) had significant increase from 5 to 6.71 (p<0.05). 7 parents (41.2%) were satisfied with acupoint in hottest period of summer and 16 parents (94.1%) wanted to have their children get treated again in next year. From the survey, inconveniences of acupuncture were weak attachment of the acupoint (23.5%), long attaching time (11.8%), pressure about number of treatments (5.9%), worry about side effects (5.9%). Side effects have been reported; 2 pruritus (11.8%), 1 pruritus and erythema (5.9%). Conclusions Acupoint sticking in hottest period of summer improves lung symptoms in children older than three years old. However, the ways to reduce the side effects and inconveniences are needed.
