This study was designed to examine the relationship between clinical symptoms, self-efficacy, and performance of women with osteoarthritis. It is a survey study of 60 women who were diagnosed as osteoarthritis and given medical treatments from September, 2005 to October, 2005 in hospital 'H' located in Yongin-si. For clinical symptoms, radiographs of the subjects' knees were taken and evaluated the pathology grade by the Kellgren-Lawrence grade. Pain and stiffness was measured by the measure of WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index), and functional reach test was measured in order to examine balancing abilities. Self-efficacy was measured by a tool which has revised the ASES (Arthritis Self-Efficacy Scale), and performance was measured by recording the difficulty of the WOMAC measurements themselves, and the time taken for 20 m walking, going up and down 9 stairs, and 5 sit-down and stand-up repetitions. The resulting differences in the other variables according to performance and the relationship between performance with variables are the following. First, an increase in pain in women with osteoarthritis led to decreased functional ability. Second, an increase in stiffness in women with osteoarthritis led to a decrease in functional ability. Third, a decrease in balance in women with osteoarthritis led to a decrease in functional ability. Fourth, a decrease in self-efficacy in women with osteoarthritis led to a decrease in functional ability. Fifth, the variables for estimating the performance by self-report were pain and self-efficacy. The variables for estimating the performance by recording the time taken was balance and self-efficacy. As a result factors such as pain, balance and self-efficacy in women with osteoarthritis were closely related to performance. Based on the results, it seems that physical therapy programs to decrease pain and to increase the balance in women with osteoarthritis, and psychological approaches to increasing self-efficacy are needed. I hope that the results of this study will be useful data for clinical management and intervention for women with osteoarthritis.

Magnesium ($Mg^{2+}$) transport across the plasma membrane of cardiac myocytes appears to be under hormonal control. Repeated stimulations with adrenergic or histaminergic agonist produced a progressive decrease in $Mg^{2+}$ efflux from hearts. Thus we hypothesized that the $Mg^{2+}$ efflux may be resulted from a down-regulation of receptors or from a depletion of $Mg^{2+}$ from intracellular pool(s) in the hearts. In the present study, the regulation of $Mg^{2+}$ homeostasis by receptor stimulation was studied in perfused rat and guinea pig hearts. The successive short addition of norepinephrine (NE) to rat and guinea pig, and of histamine (HT) to perfused guinea pig hearts induced a progressive decrease in $Mg^{2+}$ efflux. These $Mg^{2+}$ effluxes were blocked by propranolol or ranitidine, respectively. These decrease in $Mg^{2+}$ efflux were inhibited by sodium cyanide (NaCN), which increases intracellular $Mg^{2+}$ ($[Mg^{2+}]_i$) levels. When NE (or HT) was added after HT (or NE), this efflux was also decreased in the guinea pig hearts. In the rat hearts and myocytes, HT did not stimulate $Mg^{2+}$ efflux. But NE produced a large $Mg^{2+}$ efflux after stimulation with HT. 8-(4-Chlorophenylthio)-adenosine cAMP (cAMP), like NE and HT, also induced a progressive decrease in $Mg^{2+}$ efflux in guinea pig hearts. This effect was inhibited by NaCN. These data provide evidence that the progressive decrease in receptor-stimulated $Mg^{2+}$ efflux is considered to be due to a decrease in $[Mg^{2+}]_i$ levels rather than receptor down-regulation.

Infection of Vero cells with herpes simplex virus type-1 (HSV-1) resulted in a series of changes in intra-cellular free calcium concentration $([Ca^{2+}]_i)$. A significant and maximal decrease $[Ca^{2+}]_i$ was observed at 4 hours postinfection (hr p.i.) in HSV-1-infected in Vero cells. Inactivation of HSV-1 with UV irradiation and heat treatment abolished HSV-1-induced decrease in $[Ca^{2+}]_i$ at 4 hr p.i. in Vero cells. And the degree of the decrease in $[Ca^{2+}]_i$ was dependent on the amount of input virus. Taxol, which stabilizes the polymerization of microtubule blocked HSV-1-induced decrease in $[Ca^{2+}]_i$ at 4 hr p.i., suggesting that microtubule may mediate the transport of HSV-1 nucleocapsid to the nucleus of infected cell. Treatment of HSV-1-infected Vero cells with metabolic inhibitors such as cycloheximide, cordycepin, or acyclovir partially reversed the decrease in $[Ca^{2+}]_i$ at 4 hr p.i.. Thus, it is suggested that HSV-1 induced decrease in $[Ca^{2+}]_i$ at 4 hr p.i. in Vero cells may play an important role in the multiplication of HSV-1.

Objectives This study investigated the effects of Cheongyeonsan for allergic rhinitis. Methods First, the GS/MS was used to analyze the effects of Cheongyeonsan by measuring inflammatory markers. Second, 3 groups of 10 6-week-old BALB/c mice were divided into Ctrl (no treatment), ARE (allergic rhinitis-induced without treatment), and CRT (allergic rhinitis-induced after Cheongyeonsan treatment) groups. Ovalbumin (OVA) was used as an antigen to induce allergic rhinitis and sensitization was performed by intraperitoneal injection of 0.1% OVA solution 21, 14, and 7 days before the onset of allergic rhinitis. Allergic rhinitis was induced by dropping OVA solution on the nasal cavity of each mouse for 5 days after the last sensitization. Seven days after the first induction, second induction was introduced by the same method. After making the section, MMP-9, substance P, $TNF-{\alpha}$, $NF-{\kappa}B$ p65, COX-2, iNOS and Nrf, apoptotic cells were observed by Masson trichrome staining, immunohistochemical staining, TUNEL of nasal mucosal tissues of each group. Results GC/MS results showed undecanoic acid. Masson trichrome results showed that the CRT group had less respiratory epithelial damage. Immunohistochemical staining showed CRT group had 58% decrease in MMP-9, 61% decrease in substance P, 55% decrease in $TNF-{\alpha}$, 38% decrease in $NF-{\kappa}B$ p65, 53% decrease in COX-2, 54% decrease in iNOS, 87% increase in Nrf compared to those of the ARE group. TUNEL showed a positive reaction of 84% increase in apoptotic cells greater than that of the ARE group. Conclusions Cheongyeonsan alleviates nasal mucosal damage and reduces inflammatory mediators from allergic rhinitis-induced mice.

Objectives: The information on the depth where pulse wave appears is as important as pulse waveform. The aim of this study was to classify pulse pattern using pressure-height(P-H) volume-curve by 5 applied pressure levels to find out the information on the depth of pulse and interpret the floating & sinking pulse in oriental medical pulse diagnosis. Methods: We used 3 dimensional pulse imaging analyser (DMP-3000, DAEYOMEDI Co., Korea), which measures radial pulse waveforms noninvasively by way of tonometric method at 5 applied pressure levels, and shows P-H volume-curves by applied pressure. 448 subjects were enrolled, pulse waveforms were measured and the P-H volume-curves were gained on the three locations of Chon, Kwan, and Cheok. Results: Gained P-H volume curves were classified into 3 types ; increase type, decrease type, and increase-decrease type. Increase-decrease type appeared more often on Chon and Kwan, while increase type appeared more often on Cheok. In a few cases, decrease-type appeared on Chon and Kawn, however it never appeared on Cheok. Conclusions: Through the classification of pulse by P-H volume-curve, we gained the information on the depth of pulse. We speculate the decrease type as floating pulse, the increase-decrease type as middle pulse, and the increase type as sinking pulse in oriental medical pulse diagnosis. After more researches on P-H volume-curve by applied pressure, the P-H volume-curve may be used as an important factor for pulse diagnosis.

The forest of the Huaphanh Province (HP) has continued to decrease at 0.6% (10,560 ha) per year from 1992 to 2010. In the past few decades, the government of Laos and the Huaphanh Provincial Authority have been trying to address the root causes of deforestation. This study attempts to examine the factors effecting the decrease of the forest cover in the HP by analyzing the influence of the local socio-economic development and implementation of forest management policies on changes in the forest cover. The social data of the province focused on population growth and distribution between urban and rural areas including the number of poor people and the economic growth of three sectors, namely agriculture and forestry, industry, and service, while the implementation of the state forest management policy focused on the state forest management plan, tree plantation, forest land use planning and allocation to households, and shifting cultivation including annual upland rice and maize cultivation. In addition, government reports on socio-economic and rural development including poverty eradication of other provinces, where an increase in the forest cover was observed, were also collected and analyzed using qualitative and comparative analysis. The results from this study indicate that the decrease in forest cover in the Huaphanh Province appears to depend on a very slow economic growth and reduction in rural poverty of the province. The increase in the rural population in the province led to an increase in farm households and are as for shifting cultivation. As a result, forests were cleared leading to a decrease in the forest cover.

Myocardial ${\alpha}_1-adrenoceptors$ have been shown to mediate a biphaslc inotropic response that was characterized by a transient decline followed by a sustained increasing phase in guinea pig ventricular muscle. Recently one group reported that an ${\alpha}_1-adrenoceptors-induced$ intracellular $Na^+$ decrease is linked to fast $Na^+$ channel inhibition and another group reported that it is linked to $Na^+$-$K^+$ pump activation by ${\alpha}_{1b}-adrenoceptors$. But until now, its mechanism is not clear. Therefore, to see whether the $Na^+$channel or $Na^+-K^+$ pump is related to a decrease in intracellular $Na^+$ activity and/or the negative inotropic response, and which ${\alpha}_1-adrenoceptor$ subtype was involved in the decrease in intracellular $Na^+$activity by phenylephrine, we used conventional and sodium selective microelectrodes, and tension transducer to determine the effects of ${\alpha}_1-adrenergic$ stimulation on membrane potential, intracellular $Na^+$ activity, and twitch force in guinea pig ventricular muscles. $10^{-5}$ M Phenylephrine produced a slight hyperpolarization of the diastolic membrane potential, a decrease or increase in $a_N^i_a$, and a biphasic inotropic response. The negative inotropic response accompanied by a decrease in intracellular $Na^+$activity, whereas in muscles showing a remarkable positive inotropic response without initial negative inotropic effect was accompanied by an increase in intracellular $Na^+$ activity. The decrease in intracellular $Na^+$ activity was apparently inhibited by WB4101, an antagonist of the ${\alpha}_{1a}-adrenoceptors$. The decrease in intracellular $Na^+$ activity caused by phenylephrine was not abolished or reduced by a block of the fast $Na^+$ channels. $V_{max}$ also was not affected by phenylephrine. Phenylephrine produced an increase in intracellular $Na^+$ activity in the presence of a high concentration of extracellular $Ca^{2+}$ (in quiescent muscle) or phorbol dibutyrate, a protein kinase C activator(in beating muscle). These suggest that the ${\alpha}_{1a}-adrenoceptors-mediated$ decrease in intracellular $Na^+$ activity may be related to the protein kinase C.

The results of immune response and antiallergic reaction were as follows. 1. Hemagglutinin titer and hemolysin titer were increased in case of AMR, AR, SNH. But the results were not recognized as having significance. 2. PFC was increased in case of AMR, AR. But the results were not recognized as having significance. 3. RFC was increased in all groups, and the results in the AR, SNH were significant. 4. In experimentation of phagocytic activity in peritoneal exudate cells, AR and SNH showed significant increase. In spleen cells AR and SNH showed significant increase. In monolymphocytus cells AMR, AR and SNH were increased, but result of AMR was of no significance. 5. I examined promotion on spleen cells transformation. As these results, AMR showed increase in $50{\mu}g/m{\ell}$, $5000{\mu}g/m{\ell}$ in comparison with control group. And in $500{\mu}g/m{\ell}$ AMR showed increase in case of 24 hours, 72 hours incubation, but showed decrease in case of 48 hours incubation. AR showed increase in all. In $50{\mu}g/m{\ell}$ SNH showed increase in comparison with control group. And in $500{\mu}g/m{\ell}$, $5000{\mu}g/m{\ell}$ SNH showed increase in case of 24 hours, 48 hours incubation, but showed decrease in case of 72 hours incubation. 6. I examined proliferation of spleen cells. As these results AMR and SNH showed the highest increase in $50{\mu}g/m{\ell}$, but showed the lowest increase in $5000{\mu}g/m{\ell}$. AR showed the highest increase in $500{\mu}g/m{\ell}$, but this result was the almost same in $50{\mu}g/m{\ell}$, $5000{\mu}g/m{\ell}$. And AMR, AR, SNH showed higher activity in Lipopolysaccharide than Concanavalin A. 7. In all groups results of PCA were decreased in 2 week. In 4 week AR and SNH showed decrease, but AMR didn't show change. In 6 week AR and SNH showed decrease, but on the contrary AMR showed increase. 8. In experimentation on histamine contents, AMR showed significant increase at first agent contact. And AR, SNH showed decrease at first agent contact, but these results were of no importance. At second agent contact AMR showed decrease, but was of no importance. AR, SNH showed significant decrease. At third agent contact, AMR showed significant increase. AR, SNH showed decrease, but these results were of no importance. From above these results, AR and SNH showed good effects on immunoreaction. And all the herb medicines in this examination showed good effects in promotion on spleen cells transformation and proliferation of spleen cells, especially activated B-cells. AR, SNH showed good effects on anti-allergic reaction, but AMR was almost inefficient. Accordingly I think that AR shall be used in disease bringing about a lowering of immunity, that is, AR shall be used in strengthening the body resistance. And I think that SNH shall be used in eliminating pathogenic factors with strengthening the body resistance. It is necessary to a deep study in future.

The ultimate objective of periodontal therapy is not only stopping the progression of periodontal disease, but also promoting the regeneration of lost periodontal tissue. Guided Tissue Regeneration, which is based on the principle that the goal of periodontal regeneration can be achieved by preventing apical migration of gingival epithelium and blocking cells originating from connective tissue, has been developed and used as a clinical procedure, and although it has shown excellent results in connective tissue healing, there have not been many studies showing its effect on the regeneration of alveolar bone loss due to periodontal disease. The objectives of this study are to investigate the result of 12 months-long treatment following guided tissue regeneration using expanded polytetrafluoroehylene membrane, and to observe the presence of regenerated alveolar bone. Forty-one teeth from 28 patients with clinical diagnosis of periodontitis has been selected. In fifteen of those interproximal intrabony defects, only flap operation had been carried out, and designated as the control group. Twenty-six intrabony defects received e-PTFE membrane following flap operation, and designated as the experimental group. Eleven teeth whose membrane had been exposed were excluded from the experiment. Various measurements including probing depth, loss of attachment, probing bone level and gingival recession have been recorded at 6th month and 12th month, and the significance of the changes has been analyzed. The results are as follows: 1. Probing depth at 6th and 12th month has shown a significant decrease in both groups (p<0.01), but significantly higher decrease was found in the experimental group compared to the control at the month(p<0.05). 2. Loss of attachment at 6th and 12th month has shown a significant decrease in both groups, but significantly higher decrease was found in the experimental group compared to the control (p<0.05). 3. Probing bone level at 6th and 12th month has shown a insignificant decrease in the control group and significant decrease in the experimental group (p<0.01). Significantly higher decrease in probing bone level was found in the experimental group (p<0.05). 4. Gingival recession at 6th and 12th month has shown a statistically significant increase (p<0.05), and the control group showed higher increase compared to the experimental group although no statistical significance was found. As these results have shown, the use of e-PTFE membrane in intrabony pockets results in marked decrease in the loss of attachment and probing bone level. This seems to indicate that e-PTFE membrane may play a role in alveolar bone regeneration in intrabony defects.
