Objectives: As the increasing of the length of the lifespan, more recent policy interest are concerned with how many years of life are lived without functional disability or activity limitation. We investigated the relationship between deprivation and activity limitation at the 251 local authority level. Methods: The data were derived from the 2010 Census 10% sample data. Crude and age-standardized activity limitation rates by gender at the ages of 50 or over and deprivation index were calculated. Mapping and multiple linear regression analysis were applied to explore relationship between area activity limitation and area deprivation. Results: There were considerable differences in activity limitation rate across the 251 local authorities. Age-standardized activity limitation rate in both male and female were strongly associated with the level of area deprivation. Especially, low social class, male unemployment, or non-apartment residents at the local level were strong positive association with local authorities' age-standardized activity limitation. Conclusion: More policy attention is needed for tackling regional inequality in activity limitation among older adults.

Oxidative stress has been reported to be one of causes of neuritis. This study examined antioxidative activities of methanol extracts of six amphibian species known to be medicinal animals (Rana catesbeiana, R. coreana, R. rugosa, R. dybowskii, R. nigromaculata, and Hyla japonica) and investigated their effects of inhibiting nitric oxide (NO) production and cytotoxicity on the murine macrophage RAW264.7 cells. As inflammation is closely associated with reactive oxygen species, assays on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, xanthine oxidase inhibitory activity, superoxide anion radical scavenging activity and NO scavenging activity of the extracts of the six species were performed to investigate their antioxidative activity. The results obtained were as follows; All extracts showed antioxidative activity, and the activity of R. dybowskii was the highest in comparison among those. Anti-inflammatory effects of the extracts were also examined, the five extracts except that of R. rugosa did not show cytotoxicity for RAW264.7 cells at the maximal concentration ($1,000{\mu}g\;mL^{-1}$). Selectivity index, meaning NO scavenging activity compared to cytotoxicity, showed the highest level in the extract of R. dybowskii. These results will be very useful basic data for future studies on prevention and treatment of human diseases to understand the biological roles of amphibian extracts throughout the antioxidative or anti-inflammatory pathways.
Trichosanthes cucumerina Linn. (cucurbitaceae) is widely used in Indian folk medicine for variety of disease conditions. The aim of present study was to evaluate the antiulcer activity of 50% ethanolic extract of fruits of Trichosanthes cucumerina Linn. (TCFE) using various experimental models of gastric and duodenal ulceration in rats. Oral administration of 50% ethanolic extract of fruits of Trichosanthes cucumerina Linn. was evaluated in rats against ethanol, aspirin and pylorus ligated gastric ulcers as well as cysteamine-induced duodenal ulcers. In all the models studied, the antiulcer activity of TCFE compared with that of cimetidine (100 mg/kg, p.o.), an $H_2$ receptor antagonist. TCFE showed significant antiulcer activity in ethanol-induced and aspirin-induced gastric ulcer models. In 19 h pylorus ligated rats, significant reduction in ulcer index, total acidity and pepsin activity was observed with TCFE, when compared with the control group. Mucosal defensive factors such as pH, mucin activity and gastric wall mucous content was found to be increased with TCFE. TCFE was also, afforded remarkable protection in cysteamine-induced duodenal lesions. The antiulcer activity of TCFE was comparable with that of cimetidine. Thus, TCFE possess significant antiulcer activity against both gastric and duodenal ulcers in rats. The antiulcer activity may be attributed to its cytoprotective action and inhibition of acid secretary parameters.
In an attempt to investigate the role of phospholipase $A_2$($PLA_2$) in interleukin-l (IL-l) induced acute lung injury, mepacrine was tried to inhibit $PLA_2$ in IL-l induced ARDS rats. For confirmation of acute lung injury by IL-l, and to know the role of neutrophils in this injury, lung leak index, lung myeloperoxidase(MPO), number of neutrophils and protein content in the bronchoalveolar lavage (BAL) and wet lung weight were measured. At the same time lung $PLA_2$ was measured to know the effect of IL-l on $PLA_2$ activity. Pulmonary surfactant was also measured for an investigation of type II alveolar cell function. Neutrophil adhesion assay was performed to know the effect of $PLA_2$ inhibition in vitro with human umbilical vein endothelial cells (HUVEC). For precise location of injury by IL-l, morpholgical study was performed by electron microscopy. Five hours after instillation of IL-l (50 ng/rat), lung leak index, protein content, number of neutrophils, lung MPO and wet lung weight were increased significantly. Five hours after IL-l instillation lung $PLA_2$ activity was increased significantly, and increased surfactant release was observed in IL-l induced ARDS rats' BAL. In contrast, in rats given mepacrine and IL-l, there was decrease of acute lung injury i.e. decrease of lung leak index, wet lung weight, protein content, number of neutrophils in BAL and decreased lung MPO activity. Mepacrine decreased surfactant release also. Interestingly, inhibition of $PLA_2$ decreased adhesion of human neutrophils to HUVEC in vitro. Morphologically, IL-l caused diffuse necrosis of endothelial cells, type I and II epithelial cells and increased the infiltration of neutrophils in the interstitium of the lung but after mepacrine treatment these pathological findings were lessened. On the basis of these experimental results it is suggested that $PLA_2$ has a major role in the pathogenesis of acute lung injury mediated by neutrophil dependent manner in IL-l induced acute lung injury.
This work aimed to study the effectiveness of cellular oxidative parameter (malondial-dehyde, protein carbonyl, and 8-hydroxy-2'deoxyguanosine). The experimental groups were aluminum treated rats and control rats. Aluminum treatd rats were given intraperitoneally aluminum nitrate nonahydrate ($Al^{3+}$, 0.2 mmol/kg) daily for 30 days except Sunday. Control rats were injected 1 ml of saline. After the dose, rats were decapitated and hippocampus and cerebral cortex were removed. The measured parameters were tissue malondialdehyde (MDA, index of lipid peroxidation), protein carbonyl (index of protein oxidation), 8-hydroxy-2'-deoxy-guanosine (8-OHdG, index of DNA oxidation), reduced glutathione (GSH) levels as well as glutathione reductase (GR) and catalase. AI concentrations in the tissues were also measured. All results were corrected by tissue protein levels. The results were as followed; 1. The concentrations of AI in the cortex and hippocampus were significantly higher in the AI-treated rats than in the control rats. 2. Antioxidative enzyme's activity, catalase and GR, were significantly higher in the AI-treated rats than the control rats. GSH levels were also higher in the AI-treated rats. 3. MDA, protein carbonyl, and 8-OHdG concentration of AI-treated rats were significantly higher than those of control rats. 4. The concentrations of antioxidants, and oxidative stress parameter were correlated with the concentrations of AI in hippocampus and cerebral cortex. Catalase and GR activity were also correlated with the concentration of AI. Based on these results, it can be suggested that intraperitoneally injected AI was accumulated in the brain and induced the increase of antioxidant levels and antioxidative enzyme activity. Also, the oxidative products of cellular macromolecules are significantly related to tissue AI concentration. Therefore MDA, protein carbonyl, and 8-OHdG are useful markers for oxidative stress on cellular macromolecules.

Purpose: This study was designed to investigate possibilities for quantitative analysis using the electromyography and sonography. For better understanding, we evaluated the correlation between the pressure pain threshold and sonography, spontaneous electrical activity in trigger points located in the upper trapezius muscle. Methods: Thirty three active subjects volunteered to participate in this study (n=33). They had a palpable taut band, exquisite spot tenderness of a nodule in a taut band, spontaneous pain, referred pain, jump sign, local twitch response, and a painful limit to full stretch range of motion. We measured Pressure pain threshold, density, white area index, root mean square, and reaction. Pearson’s correlation coefficient was calculated to estimate the relationship between the pressure pain threshold and other variables including density, white area index, root mean square, and reaction time. Results: There were significant correlations between pressure pain threshold and density (r=-0.75, p<0.01), and between pressure pain threshold and white area index (r=-0.74, p<0.01). A significant correlations between pressure pain threshold and root mean square (r=-0.59, p<0.01). The significant correlation was found between pressure pain threshold and reaction time (r=-0.64, p<0.01). Conclusion: These should indicate whether quantitative analysis can be done using the characteristics of electromyography and sonography.
This study was conducted to examine the effect of children's dietary quality, dietary habits, food behavior and health-related lifestyles according to the mother's lifestyles of health and sustainability (LOHAS). The subjects were 580 children. Mother's LOHAS attitude index was 66.85 points and 100 points was a perfect score. The mother's high LOHAS attitude items that children perceived were "My mother often communicates with the family"(3.99 points) and "My mother thinks that the family's health is more important than her health"(3.93 points). In contrast, the LOHAS attitude items for "My mother does community service activity on weekends"(2.78 points), and "My mother participates in environmental protection service activity for the local community"(2.78 points) were very low. The high LOHAS behavior index of mothers was "resource saving", whereas "social welfare" scored low. When self-perceived health status and monthly income of children was high, the mother's LOHAS score was high. The LOHAS attitude index of mothers had a meaningful impact on the children's dietary quality, dietary habits, food behavior and health-related lifestyles. The most frequent food behavior variables were "high skipping rate", "frequency of snacks is 2~4 times per week", "speed of eating is rapid", and 'meals' amount is sufficient. The highest daily life habits item was "I try to maintain a pleasant and enjoyable life style"(3.42 points). The highest nutrient intake attitude score was "I tend to eat rice everyday."(3.41 points). They were highly recognized with "moderate physical activity", "high exercise preference", "positive posture exercise", "exercise <2 days per week", and "over 30 minutes exercise time per day" for the exercise performance status items. It was verified that the higher mother's LOHAS lifestyle score is, the higher children's food behavior, daily life habits, nutrient intake, exercise performance state score are.
Objectives : The purpose of this study was to evaluate the effects of incremental dental care(IDC) program on kindergarten children. Methods : The subjects were 46 kindergarten children aged 6 who wished participation in IDC program during 5 weeks at oral health center in G-college from March to May, 2012. The data of subjects were examined into oral conditions such as toothbrushing method and frequency, modified O'leary plaque index and dental caries activity before and after IDC program. The collected data were analyzed by SPSS statistical package version 19.0. Results : 1. The rolling and fones methods of toothbrushing increased from 10.8% to 91.3% after IDC program(p<.001). The change of toothbrushing frequency showed that over 3 times a day increased from 52.2% to 76.0% after IDC program(p<.01). 2. The modified O'leary plaque index of before toothbrushing education increased from 1st visit(score 32.19) to 5th visit(score 57.14) and after toothbrushing education increased from 1st visit(score 64.45) to 5th visit(score 78.27) during IDC program(p<.001). 3. As a results of dental caries activity test before and after IDC program, it was found that the bacterial numbers in S.mutans and Latobacillus reduced from 0.74, 0.70 to 0.28, 0.41 (p<.01) and the saliva buffering capacity increased from 1.50 to 2.02(p<.001). Conclusions : It is considered very necessary that IDC program should be maintained and extended to dental clinic so as to enhance the oral health state of kindergarten children.
The purpose of this study is to describe anxiety, depression and disease activity index(SLEDAI) and correlations among these variables, to provide the basic information developing apporiate nursing interventions for the lupus patients. In this study, authors evaluated anxiety, depression and SLEDAI from 39 lupus patients at one university hospital in Seoul. Data were collected by using questionnaires and reviewing medical records. Frequencies, t-test, Duncan's multiple range test after ANOVA were evaluated with SAS program. The key results were as follows : 1. The average age of the subjects was 31.0 years and ranged from 20 to 51. Female comprised 70.9% and 79.5% were unemployed and housewife. Fifty one point nine percent of the sample had a spouse and above junior college graduates. 74.4% of the sample had a religion and average length of suffering from lupus was 66.59 months. Majority(94.9%) of the subjects had experience of hospitalization, and 55.3% had experience of learning about lupus and average number of learning was 3.9. 2. The average anxiety score of the subjects was 44.53, showing significant relationship with educational background(t=2.27, p< .05), monthly income(F=4.56. p< .05). 3. The depression score was 41.85, showing significant relationship with monthly income(F=3.81 p=0.0236) experience of learning about lupus(t=2.09, p< .05). 4. The SLEDAI score was 12.36, showing no significant relationship with demographical variables. 5. Anxiety showed positive correlations with depression(r=0.76, p< .001), SLEDAI(r=0.48, p< .01), and depression showed positive correlations with SLEDAI(r=0.42, p< .001).
The purpose of this study was to evaluate the energy intake and energy expenditure of obese children. The body weight and height were measured, and the daily energy intake and activity pattern assessed for one day, using the 24 hour recall method and interviews in 83 elementary school children (59 boys and 24 girls). The average age, height, weight, ideal body weight and obesity index in boys and girls were 11.8 years, 144.8 cm, 54.2 kg, 39.9 kg and 35.9% and 11.5 years, 140.8 cm, 48.9 kg, 36.9 kg and 33.7%, respectively. The mean daily energy intakes of boys and girls were 1,670.5 and 1,656.5 kcal; these being 76.4 and 88.5% of estimated energy requirement for Koreans, respectively. The energy intake ratio from carbohydrates, proteins and fats in boys and girls were 61.5:14.7:23.6 and 62.0:14.7:23.7, respectively. The resting energy expenditure, as estimated by the Harris-Benedict, WHO/NAO/FAO and Korean DRI formulae in boys and girls were 1,452.7, 1,239.2 and 1,629.2 kcal and 1,323.9, 1,156.0 and 1,252.4 kcal, respectively. The activity coefficient for both the boys and girls was 1.39. The daily energy expenditure of boys (1,990.7 kcal) was significantly higher than that of girls (1712.1 kcal). No significant correlations were found between the obesity index, energy intake and energy expenditure. These results suggested that a nutrition and exercise program is required to increase the energy expenditure of elementary school children. Further research will be needed to assess multiple dietary factors and dove]lop a standard method for assessing the energy expenditure of obese children.
