  • Objectives : The purpose of this study is to investigate the effect of Bacillus-fermented Scutellariae Radix acupuncture solution (SB) on interleukin(IL) production in mouse macrophage stimulatedby lipopolysaccaride(LPS). Methods : Productions of interleukins were measured y High-throughput Multiplex Bead based Assay with Bio-plex Suspension Array System based on $xMAP^{(R)}$(multi-analyte profiling beads) technology. To begin with, cell culture supernatant was obtained after treatment with LPS(1 ${\mu}g/mL$) and SB for 24 hour. Then, it was incubated with the antibody-conj${\mu}g$ated beads for 30 minutes. And detection antibody was added and incubated for 30 minutes. After incubating for 30 minutes, Strepavidin-conjugated Phycoerythrin(SAPE) was then added. Incubating for another 30 minutes, the level of SAPE fluorescence was analyzed on Bio-plex Suspension Array System. Results : The results of the experiment are as follows. SB significantly inhibited the LPS-induced production of IL-3($9.15{\pm}0.35$ pg/mL) by $6.92{\pm}0.05,\;7.21{\pm}0.11,\;6.96{\pm}0.33,\;and\;7.45{\pm}0.74$ pg/mL at the concentration of 25, 50, 100, and 200 ${\mu}g/mL$ in mouse macrophage RAW 264.7 cells (p<0.05). SB significantly inhibited the LPS-induced production of IL-5($7.30{\pm}0.48$ pg/mL) by $6.50{\pm}0.29,\;6.30{\pm}0.25,\;6.30{\pm}0.25,\;and\;5.80{\pm}0.25$ pg/mL at the concentration of 25, 50 100, and 200 ${\mg}g/mL$ in RAW 264.7 cells (p<0.05). SB significantly inhibited the LPS-induced productiion of IL-9($17.26{\pm}0.19$ pg/mL) by $15.01{\pm}0.43$ pg/mL at the concentration of 25 ${\mu}g/mL$ in RAW 264.7 cells(p<0.05). SB significantly inhibited the LPS-induced productioh of IL-13($187.80{\pm}2.90$ pg/mL) by $152.80{\pm}4.25,\;172.80{\pm}3.97,\;162.10{\pm}6.67,\;and\;165.30{\pm}11.80$ pg/mL at the concentration fo 25, 50, 100, and 200 ${\mu}g/mL$ in RAW 264.7 cells(p<0.05). SB significantly inhibited the LPS-induced production of IL-17($18.30{\pm}0.95$ pg/mL) by $13.30{\pm}1.25,\;13.80{\pm}1.11,\;13.30{\pm}0.75,\;and\;14.00{\pm}1.08$ pg/mL at the concentration of 25, 50 100, and 200 ${\mu}g/mL$ in RAW 264.7 cells(p<0.05). SB significantly inhibited the LPS-induced production of IL-23($43.90{\pm}0.83$ pg/mL by $39.50{\pm}1.26,\;38.00{\pm}1.78,\;and\;39.60{\pm}2.49$ pg/mL at the concentration of 25, 100, and 200 ${\mu}g/mL$ in RAW 264.7 cells(p<0.05). Conclusions : These results suggest that SB has anti-inflammatory activity related with its inhibition of IL-3, IL-5, IL-13, IL-17, and IL-23 production in macrophages.

  • This study investigated the possibility of phosphogypsum (PG) recycle as an embankment material by eco-toxicity experiments for S. capricornutum, T. suecica and D. magna. The eco-toxicity experiment was studied according to column leachates from PG mixing ratio, and a specific growth rate of S. capricornutum was usually higher than that of T. suecica. For D. magna, 0.3 of toxicity unit was obtained, which indicated the below of toxicity value of 1 at PG50 condition during a 48-hr test. A minor effect of column leachate samples on three organisms was observed. This study suggested that PG was satisfied with the criteria of waste recycle and could be reused at PG30 condition.

  • This study was conducted to investigate the effect of beverage (beverage HC and beverage PG) using herbs on antimicrobial activity, proliferation of hepatic cancer cell (Hep3B) lines and sarcoma 180 (S-180) and antiallergy, respectively. Beverage PG showed higher antimicrobial activity than beverage HC against Staphylococcus aureus and Pseudomonas aeruginosa. Beverage HC and PG showed the tumor suppressive effect in mice injected with S-180 cells. The growth-inhibitoy ratio against tumor cells were $66\%\;for\;10\%$ beverage HC, $61\%\;for\;10\%$ beverage PG. In an anti-cancer test using Hep3B cells, beverage PG showed higher anti-proliferating effect than beverage HC. Beverage PG showed growth-inhibitory effect of $69.2\%\;at\;100\%$ beverage PG. Beverage PG inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. In conclusion, these results suggest that beverage using herbs have an antimicrobial activity, anti-proliferating effect against Hep3B cell and S-180 tumor and will be beneficial in treatment of allergic reaction.

  • We previously reported that acidic polysaccharide from Panax ginseng induced the proliferation lymphocytes and the generation of activated killer cells. Here we found that polysaccharide (PG-75) precipitated with 75% EtOH from water extract of Panax ginseng also has both in vitron and in vivo hematopoietic activities. In vitro studied with bone marrow cells from BALB/c mouse revealed that PG-75 had direct effect on hematopoietic colony-forming cell(CFC) growth, increased granulocyte macrophage-colony forming cell numbers by 1.59 fold over than non-treated. the ability of PG-75 to modulate hematopoiesis in vivo was evaluated the bone marrow and spleen celluarity, granulocyte-macrophage progenitor cells. BALB/c female mice were administered G-75 intraperitoneally, PG-75 was found to significantly increase the number of BM cells, spleen cells, GM-CFU on 3 hours after injection. PG-75 was also able to induce significant augmentation of GM-CSF and IFN-${\gamma}$, production in sera. These studies illustrate than PG-75 has hematopoietic activities and that this agent may be useful in the prevention and/or treatment of radio- or chemotherapy-associated myelosuppression.

  • Purpose : It has been reported that endothelin-1 can be associated with the development of cyclosporine A nephrotoxicity. Levels of endothelin-1 was assayed to determine the effect of cyclosporine A on the plasma and urine levels of this peptide. Method : Nine patients who were less than 15 years of age and were also diagnosed as steroid dependent minimal change nephrotic syndrome were included in this study. Assay of endothelin-1 was done before and 3 months after cyclosporine A treatment. The mean age of the patients was $8.3{\pm}4.6$ years. Result : There was no significant differences in the plasma levels of endothelin-1 before and after 3 months of cyclosporine A treatment ($3.22{\pm}0.39$ pg/mL vs. $3.84{\pm}1.52$ pg/mL, P=0.64). Also there was no changes in the urine levels of endothelin-1 ($21.8{\pm}5.8$ pg/mL vs. $20.3{\pm}3.1$ pg/mL, P=0.30). Conclusion : No significant changes of endothelin-1 levels were found with 3 months of cyclosporine A treatment. Further studies with longer durations will help clarifying the effect.

  • Diurnal variation of particulate polycyclic aromatic hydrocarbons (PAHs) was investigated by collecting PM10 at three different sampling altitudes using high buildings in the city center of Chiang-Mai, Thailand, during the relatively cold period in late February 2008. At site-1 (12 m above ground level), B[a]P concentrations ranged from 30.3-1,673 pg $m^{-3}$ with an average of $506{\pm}477\;pg\;m^{-3}$ contributing on average, $8.09{\pm}8.69%$ to ${\Sigma}PAHs$. Ind and B[b]F concentrations varied from 54.6 to 4,579 pg $m^{-3}$ and from 80.7 to 2,292 pg $m^{-3}$ with the highest average of $1,187{\pm}1,058\;pg\;m^{-3}$ and $963{\pm}656\;pg\;m^{-3}$, contributing on average, $19.0{\pm}19.3%$ and $15.4{\pm}12.0%$ to ${\Sigma}PAHs$, respectively. Morning maxima were predominantly detected in all observatory sites, which can be described by typical diurnal variations of traffic flow in Chiang-Mai City, showing a morning peak between 6 AM. and 9 AM. Despite the fact that most monitoring sites might be subjected to specific-site impacts, it could be seen that PAH profiles in Site-1 and Site-2 were astonishingly homogeneous. The lack of differences suggests that the source signatures of several PAHs become less distinct possibly due to the impacts of traffic and cooking emissions from ground level.

  • In this study, Galerkin scheme and SU/PG scheme of Petrov-Galerkin family were applied to the shallow water equations and a finite element model for shallow water flow was developed. Numerical simulations were conducted in several flumes with convection-dominated flow condition. Flow simulation of channel with slender structure in the water course revealed that Galerkin and SU/PG schemes showed similar results under very low Fr number and Re number condition. However, when the Fr number increased up to 1.58, Galerkin scheme did not converge while SU/PG scheme produced stable solutions after 5 iterations by Newton-Raphson method. For the transcritical flow simulation in diverging channel, the present model predicted the hydraulic jump accurately in terms of the jump location, the depth slope, and the flow depth after jump, and the numerical results showed good agreements with the hydraulic experiments carried out by Khalifa(1980). In the oblique hydraulic jump simulation, in which convection-dominated supercritical flow (Fr=2.74) evolves, Galerkin scheme blew up just after the first iteration of the initial time step. However, SU/PG scheme captured the boundary of oblique hydraulic jump accurately without numerical oscillation. The maximum errors quantified with exact solutions were less than 0.2% in water depth and velocity calculations, and thereby SU/PG scheme predicted the oblique hydraulic jump phenomena more accurately compared with the previous studies (Levin et al., 2006; Ricchiuto et al., 2007).

  • Objectives: The root of Platycodon grandiflorum (PG) has been known to possess a range of pharmacological activities including anti-cancer, anti-inflammatory, and anti-oxidant effects. The present study was designed to investigate whether or not PG-induced cell death was connected with autophagy and apoptosis in NCI-H460 human lung cancer cells. Methods: Effects on the cell viability and apoptotic activity were quantified using MTT assays and flow cytometry analysis, respectively. Protein activation was measured by immunoblotting. Autophagy was measured by LC3 immunofluorescence and immunoblotting. ROS production and loss of mitochondria membrane potential (MMP) were checked with flow cytometry analysis. Results: Following exposure to PG, NCI-H460 cell proliferation decreased simultaneously inducing autophagic vacuoles and up-regulation of microtubule-associated protein 1 light chain 3 and beclin-1 protein expressions. Interestingly, pre-treated with autophagy inhibitors, 3-methyladenin or bafilomycin A1 further triggered reduction of cell viability. PG treatment also induced apoptosis that was related modulation of Bcl-2 family proteins, death receptors and activation of caspases. In addition, PG stimulation clearly enhanced loss of MMP and reactive oxygen species (ROS) generation. Conclusions: Our results suggest that PG elicited both autophagy and apoptosis by increasing loss of MMP and ROS production. PG induced-autophagy may play a cell protective role.

  • The ripening behavior of three apple cultivars, 'Tsugaru', 'Hongro' and 'Fuji' was distinctive and the involvement of POLYGALACTURONASE(PG) in the fruit softening process was confirmed to be ethylene dependent. Fruit softening is genetically coordinated by the action of several cell wall enzymes, including PG which depolymerizes cell wall pectin. Also, loss of firmness is associated with increasing of the ripening hormone, ethylene. In this work, climacteric ripening of three apple cultivars, Tsugaru, Hongro and Fuji, producing different ethylene levels and ripening responses, was examined. Correspondingly in Fuji, a linear and basal ethylene level was observed over the entire period of measurements, and Tsugaru and Hongro displayed a typical climacteric rise in ethylene production. Transcript accumulation of genes involved in ethylene biosynthesis (MdACS3 and MdACO1) and MdPG1 was studied in Tsugaru, Hongro and Fuji cultivars. Expression of MdACO1 transcripts was shown in all three ripened apple fruits. However, the MdACS3 and MdPG1 were transcribed differently in these cultivars. Comparing the MdPG1 of 'Tsugaru', 'Hongro' and 'Fuji', structural difference was discovered by genomic Southern analysis. Overall results pointed out that MdACS3 and MdPG1 play an important role in regulation of fruit ripening in apple cultivar.

  • Objectives : Patients with obstructive sleep apnea syndrome(OSAS) often complain of nocturnal enuresis. There are a few reports that OSAS patients have altered renal function, and there are some evidences that the increased release of atrial natriuretic peptide(ANP) may be involved in the pathogenesis of nocturnal urinary symptoms of OSAS patients. In this study, we measured plasma ANP concentrations during waking and sleep in OSAS patients and normal controls to investigate whether there were differences of ANP concentrations between OSAS patients and normal subjects. Methods : 27 patients with OSAS and 10 normal subjects were studied. All subjects underwent a full-night polysomnographic study. Venous blood samples were separately drawn during waking and sleep. Plasma ANP concentrations were measured using radioimmunoassay. Results : In OSAS patients, ANP concentrations during sleep($122.9\;{\pm}\;29.9pg/ml$) were significantly higher than ANP concentrations during waking($60.2\;{\pm}\;5.8pg/ml$)(p < 0.05). However, in normal subjects, there was no significant difference between ANP concentrations during waking($59.2\;{\pm}\;5.7pg/ml$) and sleep($69.6\;{\pm}\;3.0pg/ml$)(p > 0.05). There was no significant difference of ANP concentrations during waking between OSAS patients($60.2\;{\pm}\;5.8pg/ml$) and normal controls($59.2\;{\pm}\;5.7pg/ml$)(p > 0.05), and also there was no significant difference during sleep between OSAS patients($122.9\;{\pm}\;29.9pg/ml$) and normal subjects($69.6\;{\pm}\;3.0pg/ml$)(p > 0.05). Plasma ANP concentrations during sleep showed significant positive correlations with apnea index(r = 0.3846, p < 0.05) and respiratory disturbance index(r = 0.3939, p < 0.05) in OSAS patients. Conclusion : These data suggest that, in OSAS patients, plasma ANP concentrations during sleep are significantly higher than plasma ANP concentrations during waking, and there is a positive correlation between the plasma ANP concentration during sleep and the severity of sleep apnea.
