  • The effect of Artemisia argyi H. under liquid-state fermentation by Monascus purpureus (AAFM) on cognitive impairments has been studied in a mice model of diabetes-associated cognitive decline induced by streptozotocin (STZ). C57BL/6 mice (9 weeks of age, male) were separated into four groups: a normal control, STZ-induced diabetic mouse group (STZ group), Artemisia argyi H. (AA) 10 group (diabetic mouse+AA 10 mg/kg/day), AAFM 10 group (diabetic mouse+AAFM 10 mg/kg/day). Administration of AA and AAFM significantly improved glucose tolerance, as shown by the intraperitoneal glucose tolerance test (IPGTT), and ameliorated cognitive deficit, as shown by the behavioral tests including passive avoidance, Morris water maze, and Y-maze tests. After behavioral tests, the cholinergic system was examined by assessment of the acetylcholine (ACh) level and acetylcholinesterase (AChE) inhibitory activity, and the antioxidant system was also assessed by measuring malondialdehyde (MDA) and superoxide dismutase (SOD) levels in the brain and liver.

  • This study focused on the in vitro investigation of antioxidant and anti-diabetic activities, along with neuroprotection against high glucose-induced cytotoxicity, in order to evaluate the physiological effects of Zanthoxylum piperitum and Zanthoxylum schinifolium. The highest total phenolic content was measured in the 40% ethanolic extracts of Zanthoxylum piperitum (EZP) and Zanthoxylum schinifolium (EZS). The in vitro EZP antioxidant activity showed a relatively higher ABTS/DPPH radical scavenging activity and malondialdehyde inhibitory effect than that of EZS. The EZP inhibited carbohydrate hydrolysis (α-glucosidase and α-amylase) more efficiently than EZS in anti-diabetic tests. However, EZS showed a more efficient inhibition of advanced glycation end-products formation than EZP. In addition, both EZP and EZS effectively protected human-derived neuronal cells from high glucose-induced cytotoxicity. Finally, the physiological compounds were analyzed using UPLC IMS-QTOF/MSE, and the main EZP (quercetin-3-O-glucoside and 3-caffeoylquinic acid) and EZS (5-caffeoylquinic acid) compounds were identified as phenolic compounds.

  • The objective of this study is to investigate the effect of multivitamin on macrophage activity in Raw 264.7 cell and repeated oral dose toxicity in Sprague-Dawely rat of multivitamin. Raw 264.7 cells were treated with 50 and $100{\mu}g/mL$ multivitamin for 24 h. To measure the activity of macrophages, NO and TNF-${\alpha}$ assays were performed in Raw 264.7 cells. Treatment with 50 and $100{\mu}g/mL$ multivitamin for 24 h significantly increased production of NO and TNF-${\alpha}$ compared with control groups, indicating activation of macrophages. The female rats were treated with multivitamin of control group, low group (0.24 g/kg), medium group (1 g/kg) and high group (2 g/kg) intragastrically for 4 weeks, respectively. We examined the body weight, the feed intake, the clinical signs and serum biochemical analysis. We also observed the histopathological changes of liver, ovary, brain, adrenal gland, spleen, kidney, heart and lung in rats. No significant differences in body weights, feed intake, biochemical analysis and histopathological observations between control and multivitamin treatment group were found. In conclusion, multivitamin is physiologically safe and improve macrophage activity.

  • The purpose or this study was to investigate the effect or H $_2$O fraction or Dioscorea japonica Thunb(DJT) and selenium(Se) on the lipid peroxidation in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats weighing 180∼220g were divided into 5 groups: One normal rat group and 4 diabetic rat groups(the STZ-Control group, the DJT group, the DJT-Se group and the Se group). Diabetes was induced in the male rats by injection of STZ into tail vein at a dose of 45 mg/kg. The H$_2$O-fraction of DJT(500 mg/kg) was administered orally for 14 days. The supplementation was achieved with the AIN-76 recommendation diet by adding 2 mg/kg diet of selenium as Na$_2$SeO$_3$ which was prepared freshly everyday. The levels of glycogen in liver and muscle and protein in kidney, liver and muscle were measured. The liver concentrations of cholesterol and triglyceride were analyzed. Also, the malondialdehyde(MDA) levels in kidney, liver and lung were determined. The glycogen levels of liver and muscle in diabetic groups were not significantly different from the normal group. The protein concentrations of kidney, liver and muscle were not significantly different either, but the level of muscle protein was higher than STZ-Control group. The levels of liver cholesterol were significantly different between normal and STZ-Control groups and decreased in all diabetic experimental groups fed on H$_2$O-fraction of DJT and Se supplementation compared with the STZ-Control group. The levels of liver triglyceride were higher in the DJT-Se group than the STZ-Control group. The concentrations of MDA in lung decreased greatly by the administration of Se among all and the concentration of liver MDA was significantly reduced and that of DJT-Se group was the lowest. In conclusion, the results indicated that the administration of H$_2$O-fraction of DJT with selenium supplementation has a synergistic antioxidative effect by influencing on lipid metabolites and peroxidation especially in liver.

  • Clinical observation was made on 161 cases of CVA that were confirmed through brain CT, MRI scan and clinical observation. They were hospitalized in the oriental medical hospital of Kyung-Won University from January to December in 1994. 1. The CVA cases were classified into the following kinds: cerebral infarction, cerebral hemorrhage, subarachnoid hemorrhage(SAH), transient ischemic attack, hypertensive encephalopathy, and the greatest in number among them were the cases of cerebral infarction. 2. The frequency of strokes was much the same between male and female cases and most cases were over 50 of age. 3. In the case of cerebral infarction the place of the most frequent occurrences was in the MCA territory, and as for cerebral hemorrhage, in the basal ganglia area. 4. The most ordinary preceding disease was hypertension. The next was diabetes mellitus. 5. Generally it is thought that CVA occurs frequently in winter. But on the contrary this study of observation confirmed that it occurs mostly in summer. 6. The predisposing factors of cerebral infarction were usually initiated during the time of resting and sleeping and those of cerebral hemorrhage chiefly during the time of exercising. 7. As concerns the course of hospitalization, most patients passed through western medical hospitals or oriental medical hospitals. 8. For the patients the condition of whose consciousness was bad at the time of admission, the prognosis in most cases was bad. 9. The common symptoms were motor disability and verbal disturbance. 10. With regard to cerebral infarction, the average time to start physical theraphy was 11.4 days and with cerebral hemorrhage 22.7 days after stroke. 11. The duration of hospitalization was in most cases more than one month. 12. The main complication was urinary tract infection. The next was pneumonia. 13. At the time of admission to hospital, the blood pressure in most cases was high, but it well controlled at the time of discharge. 14. Most cases were given simultaneous treatment in both ways of western and oriental medicine.

  • The purpose of this study is to evaluate the relationship between high sensitive C-reactive protein (hsCRP) and pulse transit time (PPT). Apparently healthy 233 subjects had been enrolled in the health promotion center of the Pusan National University Hospital from Jan. 29 to Feb. 26, 2004. They had no previous history of diabetes, hypertension and hyperlipidemia. Subjects were categorized according to tertiles of hsCRP level [Group 1: first tertile $(0.01\;{\sim}\;0.02\;mg/dl)$, Group 2: second tertile $(0.03\;{\sim}\;0.05\;mg/dl)$, Group 3: third tertile $(0.06\;{\sim}\;0.12\;mg/dl)$, and Group 4: Fourth tertile $(0.13\;{\sim}\;16.8\;mg/dl)$]. PTT body mass index (BMI), total cholesterol (T-C), LDL-cholesterol(LDL-C), blood sugar (BS), systolic blood pressure (sBP) and diastolic blood pressure (dBP) were significantly different among hsCRP groups (p<0.05). HsCRP is positively related with BMI, tryglyceride (TG), LDL, sBP and dBP (p<0.05), and negatively related with PTT and HDL-cholesterol (HDL-C) (p<0.05). PTT is significantly negatively related with hsCRP, T-C, TG, LDL-C, BS, dBP and sBP (p<0.05). The hsCRP and PTT were related before controlling BMI, T-C, LDL-C, sBP, and dBP, but not related after conkolling. The relationship between hsCRP and PTT depends on cardiovascular disease risk factors.

  • We introduced the physiological responses of aging, active aging and also suggest the impact of physical exercise on body health status and elderly immunity. In this purpose, we searched the Pub Med data base for the articles (include our experimental papers) and review papers having the terms 'Aging', 'Active aging' and 'Physical activity and elderly' in the title, published from 1999 until 2018. The results were as follows: Exercise training has been extensively studied about the reduction of inflammation, oxidative stress, disease, and aging in syndrome X patients and elderly. Combined and aerobic or resistance exercise training could reduce obesity, insulin resistance, type 2 diabetes and hypertension. Exercise training has been extensively studied in cancer settings as part of prevention or treatment strategies. From this research, regular exercise has the potential to target tumor growth through regulation of inflammation and immune responses such as lactate clearance, NK cell activation (innate immunity), activation of cytotoxic immune cells, T cell activation (adaptive immunity), and immune surveillance. However, Endurance physical activity not only induces thermogenesis and diverse sports injuries but also elicits mobilization and functional enhancement of monocytes, neutrophils (which is caused by the cytokine changes such as TNF-alpha, IL-1) whereas it suppresses cell mediated immunity causing to increased susceptibility to inflammation and infections like cough and URTIs (upper respiratory track infections) in young and especially in elderly people. Therefore, Strategies to prevent physical fatigue, sports injuries include avoid overtraining, Adequate recovery and various type of rest during and after physical activity and assuring adequate nutrition supplementation such as glutamine, vitamin B, vitamin C, carbohydrate, ion or berry-contain sports beverages is helpful in physically active elderly.

  • This study was a preliminary study to establish diagnostic criterias and treatment for Orofacial Movement Disorders. The 33 Orofacial Movement Disorder patients who were visited in the department of Oral Medicine from September, 2007 to December, 2007 were selected for this study. We analyzed the age, sex, systemic diseases, the diagnosis and the cause of the patients' chief complaints, the self-consciousness and the types of orofacial movements. The obtained results were as follows : 1. Female were predominant in orofacial movement disorders(81.82% vs 18.18%) and mean age was 78.78(56 to 87) years. 2. They almost had systemic diseases(81.82%). Hypertenstion was the most common disease(22.41%) and diabetes mellitus(17.24%), depression(8.62%), gastritis(8.62%) in turns. 3. In clinical manifestation, temporomandibular disorder was the most frequently complained symptom(33.33%), and soft tissue disease(21.57%), burning mouth syndrome(17.65%), orofacial movement itself(15.69%), diffuse orofacial pain(6명, 11.76%) in turns. 4. Most orofacial movement disorders are idiopathic(72.73%), and related to prosthetic treatment(24.24%), related to antidepressant medication(3.03%) in turns. 5. The jaw-closing type was the most common type of orofacial movement disorders, and lateral type(33.33%), jaw-opening types(16.67%) in turns. 6. There were more patients who did not conscious of their orofacial movements than those who did.(54.55% vs 45.45%). In conclusion, dentists must be consider the orofacial movement disorders in patients who have orofacial pain. Also, dentists should obtain a proper history and perform a clinical examination to avoid misdiagnosis and inappropriate, irreversible treatment.

  • Purpose: The study purposes were to describe the process of developing the Korean versions of the Six Dimension Scale of Nursing Performance (Six-D) and Student Nurse Stress Index (SNSI) and psychometric evaluation of the two measurements. Methods: This was a methodology study using a descriptive cross-sectional design with 51 nursing students in 4th year of university. Internal consistency reliability was assessed using Cronbach alphas. Construct validity was determined by exploring correlations among Six-D, SNSI, objective structured clinical examination (OSCE), self-efficacy and grade point average (GPA). Results: Internal consistency reliability of Six-D and SNSI was acceptable with Cronbach's ${\alpha}$ of .95 and .82. Correlation analysis to determine construct validity revealed that Six-D presented positive correlations with OSCE (r=.109~.272) and self-efficacy (r=.005~.161) and negative correlation with GPA (r=-.246~-.394), although all were not statistically significant. SNSI presented all negative correlations with OSCE (r= -.007~-.238), self-efficacy (r=-.246~-.394), and GPA (r=-.092~-.426) and were mostly statistically significant except OSCE. Conclusion: Six-D needs more evidence to confirm validity to predict observed clinical competency and theoretical relationships with self-efficacy and GPA. However, SNSI presented trends of expected relationships with relevant variables. Therefore, further research is recommended in testing validity of Six-D with other student populations.
