This study was performed to examine the increasing biological activities of both nerve growth factor induction and anti-aging activity of gastrodia (Gastrodia elata) with fermentation process. Antioxidant activities, taken in the fermenting, were investigated to verify utility value of gastrodia for functional food and cosmetics. Fermented gastrodia extracts showed higher antioxidant activities than dried gastrodia extracts. During the routine check of all the practical use potential as functional food, inhibition effect of angiotensin converting enzyme (ACE) and xanthine oxidase (XOase) was tested among water extracted dried gastrodia (WEDG), water extracted fermented gastrodia (WEFG), 70% ethanol extracted dried gastrodia (EEDG) and 70% ethanol extracted fermented gastrodia (EEFG). DPPH was shown as WEDG = $64.14{\pm}0.89%$, WEFG = $66.21{\pm}1.03%$, EEDG = $82.25{\pm}0.52%$, and EEFG = $82.36{\pm}2.37%$. ABTS was shown as WEDG = $54.15{\pm}1.37%$, WEFG = $60.24{\pm}2.25%$, EEDG = $59.18{\pm}1.86%$, and EEFG = $77.17{\pm}4.23%$. Therefore, ACE activity was dramatically inhibited by EERG while there was no difference of XOase inhibition between EEFG and EERG. Nerve growth factor (NGF) activity was measured and indicated about 40% increased neurite growth effect. To conclude, biologically active compounds of gastrodia were increased by fermentation process. It seems to be that ferment gastrodia enhance the use ranges from functional food to fuctional cosmetics, and to all processing industry.

The inhibitory activity of Aquillariae Lignum (Thymelaeaceae) on type Ⅰ immediate hypersensitivity of the anaphylactic type in the wistar rat model of passive cutaneous anaphylaxis, an IgE-mediated, mast cell-dependent reaction. Administered orally at 250, 500 mg/kg body weight 1 h before the challenge, Aquillariae Lignum potently inhibited PCA in rats which disodium cromoglycate showed poor inhibitory activity. Aquillariae Lignum inhibited compound 48/80-induced anaphylaxis 100% with a dose of 0.5 g/kg body weight at 1 h before or 5 and 10 min after injection of compound 48/80. Aquillariae Lignum (0.05-1.6 mg/ml) also exhibited the dose-related inhibitory effect on compound 48/80-induced histamine release from rat_peritoneal mast cells. Moreover, it was clearly demonstrated that Aquillariae Lignum and disodium cromoglycate disodium cromoglycate potently inhibited such type Ⅰ allergic reactions as anaphylactic shocks, suggesting that these drugs, at least in part, share the same mechanism of action It is suggested that Aquillariae Lignum may exert a stronger inhibition on the mast cell degranulation process. Since Aquillariae Lignum (1.0 mg/ml) inhibited about 90% of histidine decarboxylase activity, the inhibitory activity of Aquillariae Lignum for histamine release was considered to be derived from the inhibition of histidine decarboxylase activity. It results from increased expression of the mRNA coding for histidine decarboxylase, as assessed by Northern blot analysis after a 12 h incubation to P-815 cells with dexamethasone plus 12-O-tetradecanoylphorbol-13-acetate. The addition of Aquillariae Lignum to P-815 cells with dexamethasone plus 12-O-tetradecanoyl-phorbol-13-acetate, significantly inhibited the histidine decarboxylase gene expression. Tumor necrosis $factor-{\alpha}$ was not constitutively expressed in P-815 cells. Substance P selectively activates the tumor necrosis $factor-{\alpha}$ gene expression in P-815 cells. Aquillariae Lignurm inhibited substance P-induced tumor necrosis $factor-{\alpha}$ gene expression. Furthennore, The effect of Aquillariae Lignum on the mRNA expression of novel protein kinase C ${\delta}$ a major isoform of mast cells, was examined by Northern blot analysis. The expression of novel protein kinase C ${\delta}$ mRNA in the presence of Aquillariae Lignum was significantly lower than in the absence of Aquillariae Lignum. These results suggest the possibility that the inhibition of allergic reaction by Aquillanae Lignum should be regulated by tumor necrosis $factor-{\alpha}$ and novel protein kinase C ${\delta}$.
The purpose of this study was to develop the Constraints in Physical Activity Scale for people with physical Disabilities(CPASD) which measures the constraints in physical activity of people with physical disabilities. For this study, the 5 step analytic framework of unified validity developed by Messick (1995), the framework for conducting a strong program of construct validation by Benson (1998) method were applied. Furthermore, the validity of CPASD was systematically presented by applying common factor model and measurement model to 264 persons with physical disabilities. The conclusion based on the results and discussions of this study is as follows. First, CPASD presented evidence of job validity. Four factors (17 items) were developed, consisting of leader constraints, economic constraints, prejudice, and exercise environment constraints through the analysis of the factor structure and the fit of factor coefficients. Second, the factor structure of the developed CPASD (leader constraint, economic constraint, prejudice, exercise environment constraint) was statistically distinguished and stably reflected the existing exercise participation constraints theory. Third, the developed CPASD presented evidence of the validity of the criteria. Leader constraints and prejudice were negatively correlated with positive motor emotions, leader constraints, prejudice, and exercise environment constraints were positively correlated with negative motor emotions. Therefore, in future research, it is necessary to reevaluate the current system and actual condition related to leader constraints, economic constraints, prejudices, and exercise environment constraints derived as factors of CPASD. To do this, it is necessary to judge the degree of reality based on the causal relationship verification and IRT theory using CPASD.
Heterotrophic activity, total bacteria and salinity were determined seasonally in the estuary of Naktong River over half tidal cycle. Heterotrophic activity was determined by the uptake of [U- $^{14}$ C]glucose. Heterotrophic activity fluctuated with the tides and was decreased as salinity increased. Teh great activity occurred near low ebb tide at all seasons except summer. The main environmental factor affecting hetreotrophic activity was the salinity rather than water temperature in the estuary of Naktong River. In order to estimate the effect of salt, salt was added to estuarine water. Vmax for glucose of salt-added water was 17% and 77% of original estuarine water at station 1 and 2 respectively and slight increase was observed at station 3. Respiration rate and Kt+Sn for glucose of salt-added sample increased at all 3 stations. The increase of the Kt value implies the reduced affinity of bacterial population for glucose. The effects of salinity on the heterotrophic activity were more extensive in the upper region of estuary than at the mouth.
This study investigated the hypothesis that purposeful activity is an intrinsic motivator. Affecting exertion during the performance of purposeful and nonpurposeful activity was studied in 30 elementary school students. The subjects acted as their own controls in the performance of other exercise. The three experimental exercises were jumping rope, defined as a nonpurposeful activity, and jumping rope with reinforcement, defined as purposeful activity I, and jumping rope with double reinforcement (food), defined as purposeful activity II. Duration and cessation of exercise were entirely controlled by the subject. The number of jumps were measured immediately after cessation of exercise and duration of exercise in seconds by observer. The results were as follows : 1. There was a significant difference in the required time of performance between purposeful and nonpurposeful jumping (p< .05). 2. There was a significant difference in the number of jumps between nonpurposeful and nonpurposeful jumping after reinforcement. (p< .05). Implications for practice and further research are discussed.
With particular regards to the hepatitis A virus (HAV), a terminal dry-heat treatment ($100^{\circ}C$ for 30 min) process, following lyophilization, was developed to improve the virus safety of a solvent/detergent-treated antihemophilic factor IX concentrate. The loss of factor IX activity during dry-heat treatment was of about 3%, as estimated by a clotting assay. No substantial changes were observed in the physical and biochemical characteristics of the dry-heat-treated factor IX compared with those of the factor IX before dry-heat treatment. The dry-heat-treated factor IX was stable for up to 24 months at $4^{\circ}C$, The dry-heat treatment after lyophilization was an effective process for inactivating viruses. The HAV and murine encephalomyocarditis virus (EMCV) were completely inactivated to below detectable levels within 10 min of the dry-heat treatment. Porcine parvovirus (PPV) and bovine herpes virus (BHV) were potentially sensitive to the treatment. The log reduction factors achieved during lyophilization and dry-heat treatment were ${\ge}5.60$ for HAV, ${\ge}6.08$ for EMCV, 2.64 for PPV, and 3.59 for BHV. These results indicate that dry-heat treatment improves the virus safety of factor IX concentrates, without destroying the activity. Moreover, the treatment represents an effective measure for the inactivation of non-lipid enveloped viruses, in particular HAV, which is resistant to solvent/detergent treatment.
The use of transforming growth $factor-{\beta}1$ which functions as a potent biologic mediator regulating numerous activities of wound healing has been suggested for the promotion of periodontal regeneration. The mitogenic effects of transforming growth $factor-{\beta}1$ on human periodontal ligament cells and human gingival fibroblasts were evaluated by determining the incorporation of $[^3H]-thymidine$ into DNA of the cells dose-dependently. Cells were prepared with primary cultured fibroblasts and periodontal ligament cells from humans, and used in experiments were the fourth or sixth subpassage. Cells were seeded with serum free Dulbecco's modified Eagle medium containing 0.1% bovine serum albumine. The added concentrations of transforming growth $factor-{\beta}1$ were 0.25, 0.5, 1, 2.5, 5ng/ml and transforming growth $factor-{\beta}1$ were added to the quiescent cells for 24hours, 48hours, 72hours. They were labeled with lnCi/ml $[^3H]$ thymidine for the last 24hour of the each culture. The results were presented as the mean counts per minute (CPM) per well and S.D. of four determinations. The results were as follows. : The DNA synthetic activity of human gingival fibroblasts was increased dose-dependently by transforming growth $factor-{\beta}1$ at 24 hours, 48 hours and 72 hours. The maximum mitogenic effects were at the 48 hour application of transforming growth $factor-{\beta}1$. The DNA synthetic activity was generally more decreased at the 72 hour application than at the 48 hour the application of transforming growth $factor-{\beta}1$. The DNA synthetic activity of human periodontal ligament cells was increased dose-dependently by transforming growth $factor-{\beta}1$ at 24 hours and 48 hours. But the DNA synthetic activity was decreased at 5ng/ml of the 72 hour application. The maximum mitogenic effects were also at the 48 hour application of transforming growth $factor-{\beta}1$. The DNA synthetic activity of human periodontal ligament cells was generally more decreased at the 72 hour application than at the 48 hour application of transforming growth $factor-{\beta}1$. In the comparision of DNA synthetic activity between the human gingival fibroblasts and human periodontal ligament cells, the human gingival fibroblasts had more activity than the human periodontal ligament cells at all time application with the concentration of transforming growth $factor-{\beta}1$. In conclusion, transforming growth $factor-{\beta}1$ has an important roles in the stimulation of DNA synthesis in human periodontal ligament cells and human gingival fibroblasts, which means an increase in collagen synthesizing cells and thus, may be useful for clinical application in periodontal regenerative procedures.
For the removal of raffinose and stachyose related to flatulence in soybean, ${\alpha}-Galactosidase$ activity of six commercial enzyme preparations was compared and their enzymatic characteristics were investigated. Among the tested enzymes, one product from Aspergillus niger was shown to be the most potent in ${\alpha}-Galactosidase$ activity. The enzyme characteristics of the selected preparation were shown to be pH 4.0-4.5 for optimum activity, pH 4-5 for optimum stability and $45^{\circ}C$ for optimum activity. Upon reaction on a synthetic substrate, $p-nitrophenyl-{\alpha}-D-galactoside$, Michaelis constant was 2.08 mM and maximum velocity was 435 micromoles of substrate/minute/g enzyme preparation. The enzyme was proved to be essential for SH group for its activity and capable of hydrolyzing raffinose, sucrose and $p-nitrophenyl-{\alpha}-D-galactoside$ almost completely. Thin-layer chromatographic analysis exhibited that the enzyme treatments of raffinose and stachyose were resulted to produce only monosaccharides in 2 hours of hydrolysis. It was, therefore, assumed that the flatulence factor in soybean foods can be easily removed by the use of enzymes showing ${\alpha}-Galactosidase$ activity.
Background : The central physiological derangement of hemorrhagic fever with renal syndrome (HFRS) caused by hantaan virus (HTNV) is a vascular dysfunction, manifested by hemorrhage, impaired vascular tone and increased vascular permeability. Platelet activating factor (PAF), whose actions are mediated through a specific receptor, is a potent bioactive lipid. PAF has diverse biological functions in the vascular system, such as increasing vascular permeability, adhesion of leukocytes to the endothelium and reduction of cardiac output, which result in hypotension and shock. The goal of the present study was to investigate whether PAF is involved in the pathogenesis of HFRS. For this purpose, we evaluated the effect of HTNV on the expression of PAF receptor (PAF-R) and on the activity of PAF-acetylhydrolase (PAF-AH) instead of PAF because PAF is rapidly degraded by PAF-AH in vivo. Materials and methods : To evaluate the expression of PAF-R, we performed reverse-transcription PCR, western blot and FACS analyses using HTNV-infected human umbilical vein endothelial cells (HUVECs) and non-infected (control) HUVECs. In addition, we measured the activity of plasma PAF-AH in HFRS patients and normal healthy persons. Results : The mRNA and protein expression of PAF-R was increased in HTNV-infected HUVECs compared with control HUVECs at 2 and 3 days post-infection (d.p.i.). FACS analysis showed that HTNV induced the surface expression of PAF-R in HUVECs from 2 d.p.i. The activity of plasma PAF-AH was 2.5-fold lower in HFRS patients than in normal healthy persons. Conclusion : Increased PAF-R expression by HTNV might increase the responsiveness to PAF in endothelial cells. Reduced PAF-AH activity in the blood of HFRS patients might delay PAF degradation. These results suggest that changes in PAF-R and PAF-AH by HTNV might influence to PAF activity and might be involved in the vascular dysfunction of HFRS.

Objective: The demands for measures to improve disease resistance and productivity of livestock are increasing, as most countries prohibit the addition of antibiotics to feed. This study therefore aimed to uncover functional feed additives to help enhance livestock immunity and disease resistance, using Acanthopanax sessiliflorus fruit extract (ASF). Methods: ASF was extracted with 70% EtOH, and total polyphenolic and catechin contents were measured by the Folin-Ciocalteu and vanillin assay, respectively. The 3D4/31 porcine macrophage cells ($M{\Phi}$) were activated by phorbol 12-myristate 13-acetate (PMA), and cell survival and growth rate were measured with or without ASF treatment. Flow-cytometric analysis determined the lysosomal activity, reactive oxygen species levels (ROS), and cell cycle distribution. Nuclear factor kappa B ($NF-{\kappa}B$) and superoxide dismutase (SOD) protein expression levels were quantified by western blotting and densitometry analysis. Quantitative polymerase chain reaction was applied to measure the lipid metabolism-related genes expression level. Lastly, the antibacterial activity of 3D4/31 $M{\Phi}$ cells was evaluated by the colony forming unit assay. Results: ASF upregulated the cell viability and growth rate of 3D4/31 $M{\Phi}$, with or without PMA activation. Moreover, lysosomal activity and intracellular ROS levels were increased after ASF exposure. In addition, the antioxidant enzyme SOD2 expression levels were proportionately increased with ROS levels. Both ASF and PMA treatment resulted in upregulation of $NF-{\kappa}B$ protein, tumor necrosis factor $(TNF){\alpha}$ mRNA expression levels, lipid synthesis, and fatty acid oxidation metabolism. Interestingly, co-treatment of ASF with PMA resulted in recovery of $NF-{\kappa}B$, $TNF{\alpha}$, and lipid metabolism levels. Finally, ASF pretreatment enhanced the in vitro bactericidal activity of 3D4/31 $M{\Phi}$ against Escherichia coli. Conclusion: This study provides a novel insight into the regulation of $NF-{\kappa}B$ activity and lipid metabolism in $M{\Phi}$, and we anticipate that ASF has the potential to be effective as a feed additive to enhance livestock immunity.
