We analyzed the concentration of Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Alkaline Phosphatase (ALP), Gamma Glutamyl Transferase (GGT), total protein (TP), albumin, total cholesterol (TC) and triglyceride in sera of patients (n=455) aged 60 years and older with hyperglycemia (${\geq}120mg/dL$ in serum). The average concentration of biochemicals in patient group was compared with those in reference group. Our data showed that the average concentrations of AST and TC in sera of senior patients with hyperglycemia were significantly increased by 27.5% (P<0.05) and 82% (P<0.05) in total group, 38.5% (P<0.05) and 75.0% (P<0.05) in sixty years' group, 16.0% (P<0.05) and 89.7% (P<0.05) in seventy years' group and 27.0% (P<0.05) and 79.5% (P<0.05) in eighty years' group, respectively. Patients with hyperglycemia showed a significant decrease in albumin level by 6.7% (total group, P<0.05), 4.5% (sixty years' group, P<0.05), 8.9% (seventy years' group, P<0.05) and 4.5% (eighty years' group, P<0.05), respectively. In conclusion, the high concentration of glucose in the senior patients with hyperglycemia may be a cause of severe liver function and lipid metabolism disorder.

For a prime number p, let $\mathbb{Q}_p$ denote the p-adic field and let $\mathbb{Q}_p^d$ denote a vector space over $\mathbb{Q}_p$ which consists of all d-tuples of $\mathbb{Q}_p$. For a function f ${\in}L_{loc}^1(\mathbb{Q}_p^d)$, we define the Hardy-Littlewood maximal function of f on $\mathbb{Q}_p^d$ by $$M_pf(x)=sup\frac{1}{\gamma{\in}\mathbb{Z}|B_{\gamma}(x)|H}{\int}_{B\gamma(x)}|f(y)|dy$$, where |E|$_H$ denotes the Haar measure of a measurable subset E of $\mathbb{Q}_p^d$ and $B_\gamma(x)$ denotes the p-adic ball with center x ${\in}\;\mathbb{Q}_p^d$ and radius $p^\gamma$. If 1 < q $\leq\;\infty$, then we prove that $M_p$ is a bounded operator of $L^q(\mathbb{Q}_p^d)$ into $L^q(\mathbb{Q}_p^d)$; moreover, $M_p$ is of weak type (1, 1) on $L^1(\mathbb{Q}_p^d)$, that is to say, |{$x{\in}\mathbb{Q}_p^d:|M_pf(x)|$>$\lambda$}|$_H{\leq}\frac{p^d}{\lambda}||f||_{L^1(\mathbb{Q}_p^d)},\;\lambda$ > 0 for any f ${\in}L^1(\mathbb{Q}_p^d)$.

The purpose of this study was to investigate the effect of green tea catechin on microsomal mixed function oxidase(MFO) system of kidney and brain in streptozotocin(STZ) induced diabetic rats. Sprague-Dawley male rats weighing 140$\pm$10g were randomly assigned to one control and three STZ-diabetic groups. Diabetic groups wer classified to DM-0C(catechin 0%/kg diet), DM-0.5C (catechin 0.5%/kg diet), and DM-1.0C(catechin 1%/kg diet) according to the level of catechin supplementation. Diabetes were experimentally induced by intravenous administration of 55mg/kg body weight of STZ in citrate buffer(pH 4.3) after 4 weeks feeding of three experimental diets. Animals were sacrificed at the sixth day of diabetic state. The contents of cytochrome P450 in kidney were increased by 77, 42, 49% in DM-0C, DM-0.5C and DM-1.0C groups, respectively, than normal group. The contents of cytochrome P450 in brain were increased by 43% in DM-0C group than normal group, but those of DM-0.5C and DM-1.0C groups were similar to that of normal group. The contents of cytochrome b5 in kidney were increased by 78, 38, 49% in DM-0C, DM-0.5C and DM-1.0C groups, respectively, than normal group. Meanwhile, the contents of cytochrome b5 in brain were not significantly different among all groups. The activities of NADPH-cytochrome P450 reductase in kidney of DM-group were increased by 27% than normal group, but those of DM-0.5C and DM-1.0C groups were 13 and 15% lower than that of DM-0C group. The activities in brain were also increased by 31% in DM-0C group, but those of DM-0.5C and DM-1.0C groups were similar to than of normal group. Levels of TBARS (thiobarbituric acid reactive substance) in kidney were increased by 147, 60 and 59% in DM-0C, DM-0.5C, and DM-1.0C groups, respectively, compared with normal group, but those of DM-0.5C and DM-1.0C groups were 36, 35% lower than that of DM-0C group. Meanwhile, the levels of TBARS in brain were not significantly different among four groups. These results indicate that dietary catechins in green tea play a powerful antioxidant role in reducing the lipid peroxidation enhanced by activation of MFO system in STZ-induced diabetes.

Purpose: To identify the effect of knee joint traction therapy on pain, physical function, and depression in patients with degenerative arthritis. Methods: In total, 30 patients with degenerative arthritis were randomly assigned to one of two groups: the experimental group, who underwent knee joint traction therapy, and the control group, who underwent general physical therapy (15 patients per group). Pain was measured using the visual analogue scale (VAS), physical function was measured using the Western ontario and McMaster universities osteoarthritis (WOMAC) index, and depression was measured using the Beck depression inventory (BDI). The VAS, WOMAC score, and BDI score were recorded before and after the 4-week treatment. Results: As a result of comparison within groups, the experimental and control group showed significant difference for VAS, WOMAC and BDI after the experiment (p<0.05). In comparison between the two groups, the experimental group in which knee joint traction was applied showed more significant change in VAS, WOMAC and BDI than the control group (p<0.05). Conclusion: This study showed that knee joint traction therapy was effective in improving pain, physical function, and depression in patients with degenerative arthritis.

Purpose: The purpose of this study was to investigate self-esteem, family function, and social support which might influence stress in college students. Method: Data were collected from October 15 to December 20, 2007 when 411 students completed a questionnaire which included Self-esteem scale, Family APGAR questionnaire, Multidimensional Scale of Perceived Social Support and Global Assessment of Recent Stress scale. The collected data was analyzed with the SPSS Win 14.0 statistics program. Results: The scores for stress showed significantly negative correlations with the scores for self-esteem (r= -.394, p<.001), family function (r= -.215, p<.001), and social support (r= -.249, p<.001). Self-esteem, family function and social support by friends were significant predictors and accounted for 18.5% of the variance in stress in undergraduate students. Conclusion: Future stress management programs for undergraduate students should be developed to reinforce self-esteem, family function and social support by friends.

Objectives: This study aims to identify the influential factors on the pulmonary function of targeted general residents in the areas surrounding Gwangyang Steel Mill. Methods: An PFT (Pulmonary Function Test) was conducted from May 2007 to November 2007 on 974 target residents (438 male, 536 female), including an exposed group (674 people) who resided within a radius of 5 km from Gwangyang Steel Mill in Gwangyang-si, Jeollanam-do and a control group (300 people) who resided outside a radius of 15 km. A survey related to personal characteristics, life habits, respiratory diseases and allergic symptoms, medical histories and living environments of the residents was also conducted to identify influential factors on pulmonary function. Results: As %$FEV_1$ and %FVC of the exposed group are 99.17% and 96.98%, respectively, and those of the control group are 105.47% and 101.91%, respectively, with the PFT values of the exposed group being lower than those of the control group (p<0.001), it turns out that the pollution in the industrial complex is likely to trigger a reduction in the pulmonary function of local residents. The odds ratio analysis result for asthma diagnosis history indicates that the odds ratios tend to be higher among surveyed residents who are living near above-average traffic volumes and are using beds, where it is statistically meaningful that especially the odds ratios are higher if the residences are closer to roads (p<0.01, CI=1.12-4.52). The factors that affect the FEV1 are identified as smoking, passive smoking, asthma diagnosis history, nasal congestion symptoms and allergic eye disease ($R^2$=0.154, p<0.001). The factors that affect the FVC are identified as smoking, passive smoking, asthma diagnosis history and allergic coryza ($R^2$=0.158, p<0.001). In addition, the analysis result for the relevance of air pollution levels to pulmonary function ($FEV_1$, FVC) shows that FEV1 and FVC tend to decrease as the concentration of $O_3$ increases. Conclusions: We believe that this study may provide preliminary data for the development of preventive measures for health effects on the residents and environmental health control measures for environmental pollution in the industrial complex area.

Objective: This study was to investigate the effects of Task-oriented training for Gross Motor Function Measure (GMFM), gait and balance function in cerebral palsy. Design: Randomized controlled trials. Methods: Twenty four subjects were recruited by means of a convenience sampling from Kangseo-Gu G rehabilitation center. Subjects were 24 inpatients and were randomly divided into a task-oriented training group and a conventional group. Twelve patients were experimental group who executed the task-oriented training (5 times/wk) for 4 weeks. The task-oriented program mainly focused on the capabilities of independent walking, with the angle of inclination set at 0 degrees and walking at a self-selected comfortable speed. In addition, balance training included the one-legged standing with weight-shifting and task-oriented training. Twelve patients were control group who executed only general conventional therapy (5 times/wk) for 4 weeks. All subjects were evaluated about the motor function, gait and balance function. Subjects have conducted the measured variables, GMFM, GAITRite, PDM Multifunction Force Measuring Plate after treatment. Results: There was statistically significant increase of Gross Motor Function Measure scores of the experimental group and control group after 4 weeks (p<.05). There was statistically significant increase of gait and balance function of the experimental group after 4 weeks of task-oriented training (p<.05). The experimental group showed a significantly improvement in GMFM, gait, and balance compared to the control group (p<0.05). Conclusions: This study proved that task-oriented training after stroke can improve Gross Motor Function Measure, gait and balance. Thus this study can suggest that task-oriented training for gross motor function, gait and balance be effective on the cerebral palsy.
