Objectives : We investigated the effects of mountain cultivated ginseng water boiled extract(MCG) on blood glucose and insulin levels, and examined whether lipid metabolism are improved by it in male db/db mice(a murine model of type 2 diabetes mellitus). Methods : 9 weeks old, male db/db mice were divided into 5 groups : C57BL/6J normal, control, MCG-250mg/kg (MCG-1), MCG-500mg/kg(MCG-2) and MCG-1000mg/kg(MCG-3). After mice were treated with MCG for 8 weeks, we measured body weight, food intake, fat weight, visceral organ weight and blood glucose, insulin and lipid levels. Results : 1. We found no difference in body weight, food intake, fat weight and visceral organ weight among the animal groups. 2. Compared with controls, MCG-treated mice had lower blood glucose level and higher blood insulin levels, the magnitude of which was prominent in MCG-2. 3. Compared with controls, MCG-treated mice had lower LDL-cholesterol and higher HDL-cholesterol levels. 4. Compared with controls, MCG-treated mice had blood triglyceride and free fatty acid levels, the magnitude of which was prominent in MCG-2. 5. Blood AST and ALT concentrations were not changed by MCG, indicating MCG do not show any toxic effects. Conclusions : These results demonstrate that MCG effectively increases blood insulin level and decreases blood glucose level, blood lipid levels, and prevents and improves diabetic dyslipidemia and cardiovascular disease.

Background: The aim of this study was to investigate the demographic and clinical characteristics of patients with primary frozen shoulder in a Korean population. Methods: A total of 1,373 patients whose shoulders were diagnosed with primary frozen shoulder across 11 resident-training hospitals were reviewed retrospectively. Various demographic characteristics and clinical characteristics according to gender and presence of diabetes were evaluated. Results: The average age of patients was 55.4 years. Gender proportion was 58.3% females and 41.7% males. The frozen shoulder involved the non-dominant arm in 60.7% of patients and the bilateral arms in 17.6% of patients. The average duration of symptoms was 8.9 months, and 51.3% of patients had experienced nocturnal pain. Comorbidities associated with frozen shoulder in our sample of patients included diabetes (18.7%), cardiovascular diseases (17.7%), thyroid diseases (5.4%), and cerebrovascular diseases (3.6%). The diabetic group was correlated with the following demographic and clinical characteristics: old age, involvement of the dominant arm, nocturnal pain, long duration of symptoms, and no history of trauma. Further, we found that, in males, having a frozen shoulder was significantly correlated with a history of trauma; in females, having a frozen shoulder was significantly correlated with having thyroid diseases. Conclusions: These demographic data of primary frozen shoulder in the Korean population were consistent with those of previously reported epidemiologic studies. Primary frozen shoulder with diabetes was correlated with old age, bilateral involvement, long duration of symptoms, and nocturnal pain.

First, mice were dosed with 50mg/kg of streptozotocin(STZ) twice every 24 hours to cause high blood-sugar. Then, after three days, mice were injected with 100mg/kg of STZ again. Two different dosages of Saengjihwangeumja-gami were given to the experiment groups: SA group, 15mg/kg/day, and SB group, 90mg/kg/day, in order to determine the effects of Saengjihwangeumja-gami, which has been known to be good for DM(Diabetes Mellitus). By observing weight and blood-sugar level changes, blood tolerance, the numerical value of BUN(Blood Urea Nitrogen) and creatinine in blood, and through light-electronicmicroscopic and immunohistologic investigations of pancreas and kidneys, the following results were obtained: 1. The experiment groups showed a high suppressive effect of weight-loss. 2. The experiment groups' blood-sugar and blood tolerance showed an effective lowering of blood-sugar levels. 3. The experiment groups did not show any noticeable change in the numerical value of BUN and creatinine in blood compared with that of the control groups. 4. The experiment groups showed a higher Insulin positive reaction of pancreatic islets ${/beta}-cell$ than the control groups. 5. The experiment groups showed a higher immuno-reaction against IGF- II than the control groups. 6. Observation of apoptosis of the pancreatic islets showed that the cells of experiment groups were less injured compared with those of the control groups, and fewer apoptag-positive reaction cells were seen in experiment groups than in the control groups. 7. Uunder electron-microscopy, the insulin-containing granules in pancreatic islets ${/beta}-cells$ had increased more in the experiment groups than in the control groups. 8. Under light microscopy, the injury on the inner & outer membrane of the glomerulus and epithelial cells of capillaries and cells among vessels were fewer in the experiment groups than in the control groups. 9. More apoptag-positive reaction cells in the kidney were seen in the control groups than in the experiment groups. 10. PAS-positive reaction substances had increased more in the substrate among the vessels of a glomerulus belonging to the control group than those of the experiment group. 11. Uunder electron-microscopy, the nucleonic membrane, nucleoplasm and mitochondria of proximal and distal renal tubular were more injured in the control groups than in the experiment groups. In conclusion, strong evidence for the efficacy of Saengjihwangeumja-gami in lowering blood-sugar, and in recovery and generation of pancreatic tissues injured by DM was observed. Results suggest Saengjihwangeumja-gami is an effective treatment for DM. Further study of the principles of blood-sugar dropping effects of Saengjihwangeumja-gami are needed, as well as further study of recovery and regeneration of pancreatic tissues injured by DM.

Objectives: The purpose of the study is to investigate the relationship between bone mineral density and remaining teeth in Korean adults. Methods: Using National Health and Nutrition Examination Survey(KNHANES) 5th Year 1(2010), 1,985 adults over 50 years old having bone mineral density test were selected. Male adults were 883, and female adults were 1,102. The raw data consisted of general characteristics of the subjects, bone density data, and oral examination data. The questionnaire consisted of general health survey, laboratory examination study, and nutrition study. Data were analyzed using SPSS 18.0 program for multiple regression analysis, ANOVA, t-test. The variables included general characteristics of the subjects, health behavior, diet habit, and oral health behavior. General characteristics consisted of gender, age, residence area, education level, marital status, monthly income, and vocation. Health behavior consisted of smoking, alcohol drinking, body mass index(BMI), physical activity, and mental health. Diet habit consisted of frequency of meal, milk, coffee, and calcium ingestion. Oral health behavior consisted of frequency of tooth brushing, use of oral health care devices, and oral examination. Systemic diseases were measured by the questionnaire for hypertension, diabetes mellitus, and hyperlipidemia. Bone density was measured in T-score of femoral bone, neck of femur, and lumbar vertebrae. Bone density was classified into normal($T-score{\geq}-1.0$), osteopenia(-2.5 < T-score < -1.0), and osteoporosis ($T-score{\leq}-2.5$). The remaining teeth were measured by the differences between normal teeth and missing teeth. Results: Smoking and age are the most influencing factors on the number of remaining teeth and bone density(p<0.01)(p<0.05). Those who had higher bone density, younger age, and nonsmoker significantly had more remaining teeth. Those who were men, diabetic, lowly educated women, and low birth weighted persons tended to have less number of teeth(p<0.01). Conclusions: The study suggested that there were significant differences between men and women according to the oral health management behavior and systemic disease control. Proper management of the oral health and good quality of bone mineral density can reserve the remaining teeth through the whole life.

The purpose of this study is to determine the clinical nurses' knowledge of DM and diabetes patient education aptitude so as to provide a basis for clinical nurse training with respect to diabetes patient education program. The data has been collected through the questionnaires of 42 items from the Knowledge on DM and each 16 item from the Importance on the elements of diabetes patient and the Recognition for clinical nurses, respectfully. 166 nurses from a general hospital who had participated in clinical nurse training in Sep. 28 and Oct. 4, 2001 were subject to respond the questionnaires. Analysis has been done by using statistical method such as percentage, average, standard deviation, t-test, ANOVA, Duncan test and Pearson correlation coefficients. The findings are as follows: 1. Clinical nurses' knowledge levels of diabetes 1) The average level of nurses' knowledge about diabetes is 29.37 (right answer- finding rate: 70%), which is intermediate. 2) Amongst the nurses classified by their knowledge levels about diabetes, the group with less than one year career and that with more than 5 year careers are found to have higher knowledge levels. The item with the highest right answer-finding rate was 'Please find the wrong out of the following examples about foot care'. Meanwhile, the item with highest incorrect answer-finding rate was 'what does blood sugar control aims for amongst gestational diabetes?'. 2. Clinical nurses' importance and perception levels of educational training about diabetes 1) There were no differences amongst nurses' importance level about diabetes. 2) Nurses usually had high scores(4.30) in terms of the items related to the importances about educational training. 3) There were quite high recognitions of general characteristics and symptoms about diabetes, amongst the nurse cohorts working more than one year and less than 5 years, and over 5 years, the group belonging to the internal department, that having the previous experiences of dealing with diabetes, and that having their diabetic relatives and other close people. Meanwhile, strangely, the group who identified themselves as 'not good at treating diabetes' had a high recognition level of educational training about diabetes. 3. Relationship between knowledge levels and importance & perception levels of diabetes 1) The higher knowledge about diabetes nurses had, the more importance they recognized. 2) It is found that there was no relationship between knowledge and perception of diabetes. 3) The more importance about diabetes nurses had, the higher perception they obtained. In conclusion, there is an urgent need for systematic educational programs about diabetes including technical aspects, in order to upgrade and improve nurses knowledge levels. In addition, re-educational training should be provided at regular intervals. Further, we believe the nurses with high knowledge about diabetes and interests in the provision of educations for patients can be far more confident, and in return, patients can have better self-management about diabetes obtained through educations. Based on the above-mentioned findings, we would like to make the suggestion: re-evaluation about nurses' knowledge and cognition levels should be carried out after job training programs about diabetes.

Type I diabetes, also known as insulin-dependent diabetes mellitus (IDDM) results from the destruction of insulin-producing pancreatic $\beta$ cells by a progressive $\beta$ cell-specific autoimmune process. The pathogenesis of autoimmune IDDM has been extensively studied for the past two decades using animal models such as the non-obese diabetic (NOD) mouse and the Bio-Breeding (BB) rat. However, the initial events that trigger the immune responses leading to the selective destruction of the $\beta$ cells are poorly understood. It is thought that $\beta$ cell auto-antigens are involved in the triggering of $\beta$ cell-specific autoimmunity. Among a dozen putative $\beta$ cell autoantigens, glutamic acid decarboxylase (GAD) has bee proposed as perhaps the strongest candidate in both humans and the NOD mouse. In the NOD mouse, GAD, as compared with other $\beta$ cell autoantigens, provokes the earliest T cell proliferative response. The suppression of GAD expression in the $\beta$ cells results in the prevention of autoimmune diabetes in NOD mice. In addition, the major populations of cells infiltrating the iselts during the early stage of insulitis in BB rats and NOD mice are macrophages and dendritic cells. The inactivation of macrophages in NOD mice results in the prevention of T cell mediated autoimmune diabetes. Macrophages are primary contributors to the creation of the immune environment conducive to the development and activation of $\beta$cell-specific Th1-type CD4+ T cells and CD8+ cytotoxic T cells that cause autoimmune diabetes in NOD mice. CD4+ and CD8+ T cells are both believed to be important for the destruction of $\beta$ cells. These cells, as final effectors, can kill the insulin-producing $\beta$ cells by the induction of apoptosis. In addition, CD8+ cytotoxic T cells release granzyme and cytolysin (perforin), which are also toxic to $\beta$ cells. In this way, macrophages, CD4+ T cells and CD8+ T cells act synergistically to kill the $\beta$ cells in conjunction with $\beta$ cell autoantigens and MHC class I and II antigens, resulting in the onset of autoimmune type I diabetes.

The determination of peripheral nerve conduction velocity is an important part to electrodiagnosis. Its value as neurophysiologic investigative procedure has been known for many years but normal value of digital nerve was not reported in Korea. To evaluate of digital nerve conduction velocity of median nerve for obtain clinically useful reference value and compare difference in each fingers. 71 normal volunteers(age, 19-65 years; 142 hands) examined who has no history of peripheral neuropathy, diabetic mellitus, chronic renal failure, endocrine disorders, anti-cancer medicine, anti-tubercle medicine, alcoholism, trauma, radiculopathy. Nicolet Viking II was use for detected conduction velocity and amplitude of digital nerves in median nerve. Data analysis was performed using SPSS. Descriptive analysis was used for obtain mean and standard deviation, ANOVA was used to compare each fingers and independent t-test was used to compare between Rt and Lt side also compare between different in genders. Conduction velocity of the right thumb was 49.77m/sec, index finger was 56.80m/sec, middle finger was 56.15m/sec and ring finger was 53.38m/sec. The left thumb was 50.48m/sec, index finger was 56.76m/sec, middle finger was 55.99m/sec and ring finger was 53.23m/sec. Amplitude of the right thumb was $64.30{\mu}V$, index finger was $73.95{\mu}V$, middle finger was $77.97{\mu}V$ and ring finger was $43.92{\mu}V$. The left thumb was $74.21{\mu}V$, index finger was $85.72{\mu}V$, middle finger was $88.06{\mu}V$ and ring finger was $47.28{\mu}V$. There were significantly difference between thumb, index, middle and ring fingers(p<.01) but there were no statistically difference between conduction velocity and amplitude of index and middle fingers(p>.01). The conduction velocity of index finger are faster than other fingers and amplitude of middle finger are greater than other fingers. The present results revealed that electodiagnosis can easily perform in index and middle finger for digital nerve of median nerve study.

Maturity-onset diabetes of the young (MODY) is a genetically heterogeneous subtype of Type 2 diabetes characterized (non-insulin-dependent) by early onset, usually before 25 years of age, autosomal dominant inheritance and a primary defect in insulin secretion. Mutations in the glucokinase (GCK) and hepatocyte nuclear factor (HNF)-1α genes are the major causes of monogenic forms of Type 2 diabetes mellitus. Therefore it is need to study relation with these polymorphisms by diverse analysis methods. The promotor and coding regions inclusive intron exon boundaries of the GCK, HNF-1α genes were examined by PCR-DHPLC (Polymerase Chain Reaction - Denaturing High Performance Liquid Chromatography) and direct sequencing. We extracted DNA from 11 patients and 20 normals. Then we confirmed a single-nucleotide polymorphism using PCR-DHPLC. As results, we identified one mutation (R135G) in GCK gene and two mutations (I27L, S487N) in HNF-1a and at the same time detected mutation in intron 8.
