Platelet anti-aggregating activities were evaluated with three combined crude drug preparations which have been used for 'eahyul'-one of the pathological concept in oriental medicine presumably concerning blood stasis or stagnant syndrome. The water extract of each combined preparation and each component plant was tested for their effects against ADP, arachidonic acid (AA) or collagen induced rat platelet aggregations. Mild inhibitory activities were observed with all the three tested preparations, Kaechibokryung-Hwan, Dangkqijakyak-San and Ohnkyung-Tang, and the component plants which are included in at least two of the above preparations.

The antifungal activities of the essential oil from Agastache rugosa and its main component, estragole, combined with ketoconazole, one of the azole antibiotics commonly used to treat infections caused by Trichophyton species, were evaluated in this study. The combined effects were measured by the checkerboard microtiter and the disk diffusion tests, against T. erinacei, T. mentagrophytes, T. rubrum, T. schoenleinii and T. soudanense. Susceptibility of the five Trichophyton species to the oil alone, or ketoconazole alone, differed distinctly. The fractional inhibitory concentration indices (FICI) of ketoconazole combined with estragole or A. rugosa essential oil, against the tested Trichophyton species, were between 0.05 and 0.27, indicating synergistic effects. These drug combinations exhibited the most significant synergism against T. mentagrophytes, with FICIs of 0.05 and 0.09 for estragole and the essential oil fraction from A. rugosa, respectively. Isobolograms based on the data from checkerboard titer tests also indicated significant synergism between ketoconazole and the Agastache oil fraction or estragole, against the Trichophyton species evaluated. Trichophyton susceptibility to ketoconazole was significantly improved by combination with the Agastache rugosa oil fraction or its main component, estragole.

Epistasis that may explain a large portion of the phenotypic variation for complex economic traits of animals has been ignored in many genetic association studies. A Baysian method was introduced to draw inferences about multilocus genotypic effects based on their marginal posterior distributions by a Gibbs sampler. A simulation study was conducted to provide statistical powers under various unbalanced designs by using this method. Data were simulated by combined designs of number of loci, within genotype variance, and sample size in unbalanced designs with or without null combined genotype cells. Mean empirical statistical power was estimated for testing posterior mean estimate of combined genotype effect. A practical example for obtaining empirical statistical power estimates with a given sample size was provided under unbalanced designs. The empirical statistical powers would be useful for determining an optimal design when interactive associations of multiple loci with complex phenotypes were examined.

A combined convective heat transfer study for non-Newtonian fluids was experimentally performed in uniformly heated horizontal tubes with laminar flow in the thermal entry region. Velocity profiles were fully developed at the entrance of the heated sections in the tubes. Aqueous solutions of sodium carboxymethylcellulose(CMC ) were used; their behavior showed a reasonably good fit into the power-law model, .tau.=K.gamma.$^{n}$ . The test sections were made of copper with inside diameters of 3.23 cm and 5.042 cm and lengths of approximately 300 cm. Most experimental runs displayed noticeable secondary flows caused by buoyancy ; when present, secondary flows caused significant increase in the rate of heat transfer over the purely forced-convection case. A correlation, which relates the rate of heat transfer for flows with temperature-dependent properties, free convection effects, and non-newtonian effects, was suggested.

A pot experiment was conducted to investigate the effects of soil burial depth on seedling emergences of rice (Oryza sativa) and Echinochloa spp. and to model such effects for mathematical prediction of seedling emergences. When the Gompertz curve was fitted at each soil depth, the parameter C decreased in a logistic form with increasing soil depth, while the parameter M increased in an exponential form and the parameter B appeared to be constant. The Gompertz curve was combined by incorporating the logistic model for the parameter C, the exponential model for the parameter M, and the constant for the parameter B. This combined model well described seedling emergence of rice and Echinochloa species as influenced by soil burial depth and predicted seedling emergence at a given time after sowing and a soil burial depth. Thus, the combined model can be used to simulate seedling emergence of crop sown in different soil depths and weeds present in various soil depths.

Purpose: This study was performed to identify and investigate the therapeutic effects of low-level laser (LLL) combined with a light-emitting diode (LED) on post-operative wound healing and functional recovery after hand orthopedic surgery. Methods: The study subjects were twenty patients who had passed the acute inflammatory phase after hand orthopedic surgery and were assigned equally to an experimental or a control group. Phototherapy was administered three times weekly for two weeks. Changes in wound length, edema, pain, and hand function were measured. Results: Significant differences in wound length, edema, pain, and hand function were observed between the experimental and control groups (p<0.05). However, no significant intergroup difference was observed (p>0.05). Nonetheless, a comparison of results showed changes in the experiment group over the two-week study period were significantly greater than in the control group (p<0.05). Conclusion: These findings show that combined LLL plus LED phototherapy positively influences post-operative hand rehabilitation.

The purpose of this study was to determined the converge effects of combined exercise rehabilitation on lower limb muscular function and cytokines in taekwondo player with patellofemoral pain syndrome. In this study, combined exercise rehabilitation(aquatic exercise 3 times a week, resistance exercise 2 times a week) was performed and 20 collegiate taekwondo player with patellofemoral pain syndrome(control group: n=10, combined exercise rehabilitation group: n=10) were participated for 8 weeks. Statistical significance verification was carried out by a two - way ANOVA repeated measures design as a mixture using the SPSS 18.0 program. The statistically significant level was set at 0.05. The results of this study were as following. Peak torque was higher significantly in extensor(p<.001) and flexor(p<.01) at $60^{\circ}/sec$ in the combined exercise rehabilitation group than the control group over combined exercise treatment period. Average power was higher significantly in extensor muscles at $180^{\circ}/sec$ in the combined exercise rehabilitation group than the control group over combined exercise treatment period.(p<.01). The variable of TNF-a was higher significantly in the combined exercise rehabilitation group than the control group as over combined exercise treatment period. Therefore, it can be concluded that a combined exercise rehabilitation program is effective in improving the lower limb muscular function and TNF-a in Patellofemoral Pain Syndrome patient.

The purpose of this study was to investigate effects of moxibustion at combined acupoints on sex and age in rats. This study measured the effects of moxibustion on small intestinal motility in rats. Cauterizing with moxa was applied 5 times to the acupoints on SI8, LI11 SP9 and ST36 under enflurane anesthesia in the groups divided with sex and age. In single acupoint groups, cauterizing with moxa on ST36 increased in all of sex and age groups. The SP9 group with 5, 6 weeks in female and 5, 8 weeks in male, the SI8 group with 5, 7 weeks in female and only 7 weeks in male, the LI11 group with only 5, 6, 7 weeks in female and only 7 weeks in male showed increasing on small intestinal motility. In combined acupoints groups, the SI8+SP9 group with 7 weeks in female and 5, 6, 8 weeks in male, the SI8+ST36 group with 5, 6 weeks in female and 8 weeks in male, the LI11+SP9 group with 5, 6 weeks in female and 6 weeks in male, the LI11+ST36 group with 5 weeks in female and 5, 6, 7 weeks in male showed increasing respectively. Although these different according to the sex and age in rats do not have a established tendency, the results suggested that the effects of combined acupoints of cauterizing with moxa have relation with individuality.

Objective : Arsenic trioxide ($As_2O_3$) has been used as an anticancer agent in traditional Chinese medicine for thousand years and berberine is an isoquinoline alkaloid present that has indicated significant antimicrobial activity. We have examined the combined anticancer effects of $As_2O_3$ and berberine against the human neuroblastoma (HNB) SH-SY5Y cells in vitro, and to elucidate underlying molecular mechanism. Methods : HNB SH-SY5Y cells were treated with $2\;{\mu}M\;As_2O_3$ and $75\;{\mu}g/ml$ berberine, and their survival, cell death mechanism as well as synergistic cytotoxic effects were estimated by using MTT assay, DAPI staining, agarose gel electrophoresis, flow cytometric analysis, and western blot analysis. Results : The combined treatment of two drugs also markedly decreased cell viability. The cytotoxic effects of two drugs were revealed as apoptosis characterized by chromatin condensation, DNA fragmentation, and the loss of mitochondrial membrane potential. The apoptotic cytotoxicity was accompanied by activation of caspase-3 protease as well as decreased the expression of Bcl-2, Bid, and Bcl-x/L. In addition, the cells treated with combination of two drugs also showed significantly increased intracellular reactive oxygen species levels and lipid peroxidation compared to cells $As_2O_3$or berberine only. Conclusion : Combined treatment of $As_2O_3$ with berberine induced activation of apoptotic signaling pathways in HNB SH-SY5Y cells. These results suggest that the possibility of the combined treatment of two chemotherapeutic agents with low concentration improving cytotoxic effect for cancer cells with minimal side effects.
