  • Background and Objective: Histone deacetylase (HDAC) inhibitors represent a promising class of potential anticancer agents for treatment of human malignancies. In this study, we investigated the effect of trichostatin A (TSA), one such HDAC inhibitor, in combination with docetaxel (TXT), a cytotoxic chemotherapy agent or erlotinib, a novel molecular target therapy drug, on lung cancer A549 cells. Methods: A549 cells were treated with TXT, erlotinib alone or in combination with TSA, respectively. Cell viability, apoptosis, and cell cycle distribution were evaluated using MTT (3- (4, 5-dimethylthiazol-2-yl) -2, 5-diphenyltetrazolium bromide) assay, Hochst33258 staining and flow cytometry. Moreover, immunofluorescent staining and Western blot analysis were employed to examine alterations of ${\alpha}$-tubulin, heat shock protein 90 (hsp90), epidermal growth factor receptor (EGFR), and caspase-3 in response to the different exogenous stimuli. Results: Compared with single-agent treatment, co-treatment of A549 cells with TSA/TXT or TSA/erlotinib synergistically inhibited cell proliferation, induced apoptosis, and caused cell cycle delay at the $G_2/M$ transition. Treatment with TSA/TXT or TSA/erlotinib led to a significant increase of cleaved caspase-3 expression, also resulting in elevated acetylation of ${\alpha}$-tubulin or hsp90 and decreased expression of EGFR, which was negatively associated with the level of acetylated hsp90. Conclusions: Synergistic anti-tumor effects are observed between TXT or erlotinib and TSA on lung cancer cells. Such combinations may provide a more effective strategy for treating human lung cancer.

  • Objectives : Scrophulariae Radix (SRE) is commonly used in combination with other herbs as a nutrient and health strengthening agent, and to remove 'heat' and replenish vital essence. The water-based extract of this herb can lower blood pressure in both anesthetized and concious animals, and exhibits an anti-inflammatory activity. But, there is lack of studies regarding the effects of SRE on the immunological activities in molecular levels. The present study was conducted to evaluate the effect of SRE on the regulatory mechanism of cytokines and nitric oxide (NO) in Raw 264.7 cells. Method : After the treatment of Scrophulariae Radix methanol extract, cell viability was measured by MTT assay, NO production was monitored by measuring the nitrite content in culture medium. COX-2 and iNOS were determined by Immunoblot analysis, and levels of cytokine were analyzed by sandwich immunoassays. Results : Results provided evidence that SRE inhibited the production of nitrite and nitrate (NO), inducible nitric oxide synthase (iNOS), $interleukin-1{\beta}\;(IL-1{\beta})$ and interleukin-6 (IL-6), and the activation of phospholylation of inhibitor ${\kappa}B{\alpha}\;(p-I{\kappa}B{\alpha})$ in Raw 264.7 cells activated with lipopolysaccharide (LPS). Conclusion : These findings suggest that Scrophulariae Radix can produce anti-inflammatory effect, which may playa role in adjunctive therapy in Gram-negative bacterial infections.

The results of analysis of 69 Arthritis articles public year of between 1970-1999 found that most articles(27.6%, n=19) were published since few(10.1%, n=7) were before 1994. Vast majority of articles(79.8%, n=55) were printed in The Journal of Rheumatology Health, and 79.8%(n=55) of those were quantitative research, 8.7%(n=6) were qualitative research, and 14%(n=1) was methodological research. 29.0%(n=20) of quantitative research were carried in experimental design and over half(50.8%, n=35) in nonexperimental design. Having concerned the types of treatment(or intervention) used in experimental study, the most common treatment was 'exercise' (45.0%, n=9), and other less common were 'self-help education(15.0%, n=3), home care(10.0%, n=2) supportive care(10.0%, n=2), flexibility exercise combined with local heat therapy(5.0%, n=1), relaxation training(5.0%, n=1). Of the types of exercise, aquatic exercise was 30.0%(n=6). The effect of exercise on outcome variable was found to be most strong among the other types of treatment. 18 articles of nonexperimental research were correlational research. From the analysis of correlational research, 29 concepts were identified, and the relationship between depression and other variable were strongly reported. In descriptive studies, most commonly physiological variables were examined in 5 articles(29.5%). Only one study(5.9%) explored patient's perception of the causal factors and those causality. In qualitative researches, two study were carried out by the means of grounded theory. Majority of those subjects were RA patients, and the largest number of sample were 23 and the smallest was 1 In two studies, patient's perceived causality of RA was identified as a research problems, and an experience of ADL, fatigue Phenomenon, an experience of having a total knee replacement with osteoarthritis were each found in one study. Methodological research was carried out to test validity and reliability of the RA Fatigue Scale.

  • Objectives : The moxibustion is the method using the heat stimulation done by attached and burned a moxa on a healing point or acupuncture point with chemical stimulation of a resin made from burning them. The purpose of this study is to find the physical and thermal characteristics of moxibustion in order to standardize the moxa therapy method. Methods : In this study, the thermal changes were observed by means of a testo 845 device, which is an infra-red thermometer to measure the thermal changes. Results & Conclusions : 1. The thermal changes on the external surface of moxibustion did not depend on the weight of the moxa; the external surface temperature was about $500^{\circ}C$. 2. The central thermal changes depend on the weight of moxa; the central temperatures ranged from $500^{\circ}C$ to $700^{\circ}C$. 3. The burning duration of moxibustion depend on the weight of moxa but that of external surface temperature did not depend on the weight of moxa in high degree : about $400^{\circ}C$. 4. The integral values of central and external temperature curves were proportional to the weight of moxa; that is central temperature curves were higher than that of external.

  • Olibanum (Boswellia serrata) has been shown to have anti-inflammatory, anti-arthritic and anticancer effects. This study determined the role of a water extract of olibanum in platelet-derived growth factor (PDGF)-stimulated proliferation and migration of rat aortic smooth muscle cells (RASMCs). PDGF-BB induced the migration and proliferation of RASMCs that were inhibited by olibanum extract in a dose-dependent manner. The PDGF-BB-increased phosphorylation of p38 mitogen-activated protein kinase (MAPK); the heat shock protein (Hsp) 27 was significantly inhibited by the olibanum extract. The effects of PDGF-BB-induced extracellular signal-regulated kinase1/2 was not altered by the olibanum extract. Treatment with olibanum extract inhibited PDGF-BB-stimulated sprout out growth of aortic rings. These results suggest that the water extract of olibanum inhibits PDGF-BB-stimulated migration and proliferation in RASMCs as well as sprout out growth, which may be mediated by the inhibition of the p38 MAPK and Hsp27 pathways.

  • Objectives : The purpose of this study is to analyze the use of herbal medicine as a treatment method in the case studies on warts in Korea, to identify trends in herbal medicines and herbal prescriptions according to the characteristics of individual patients and to systematically analyze concurrent therapies. Methods : Domestic databases (OASIS, RISS, NDSL, KTKP, KISS, KISTI, KISTI) were used to search for case studies related to the herbal medicine treatment of warts. There was no restriction on the time of publication. A total of 9 papers were selected. Results : A total of 13 prescriptions were presented 23 times in 18 cases. Among them, bojungikgi-tang gamibang(補中益氣湯加減方) was the most frequently prescribed. Gwakhyangjeonggi-san gamibang(藿香正氣散加減方) and Damsoeun-tang gagam were the next most frequently prescribed. 69 herbs were used in a total of 13 prescriptions. Herbs were commonly classified as heat-clearing medicine(淸熱藥), exterior-releasing medicine(解表藥), and tonifying and replenishing medicine(補益藥) in descending order. The herbs used more than 6 times included Coicis Semen(薏苡仁), Glycyrrhizae Radix et Rhizoma(甘草) (10 times), Bupleuri Radix(柴胡), and Scutellariae Radix(黃芩) (6 times). Concurrent therapies were performed except for 1 study, and they were acupuncture, moxibustion, pharmacopuncture, external agents, and cupping therapy. Conclusions : This is the first study to analyze the use of herbal medicine as a treatment method for warts in case studies performed in Korea. We hope that this study would give helpful information about the treatment of warts in clinical practices.
