Capillary blood sampling on the forearm reduces pain caused by skin puncture. The present study compared the blood glucose test results performed at different sampling sites of the forearm, finger, and vein to evaluate clinical validity of this alternative site blood sampling technique. Subjects numbered 555 including 61 diabetic patients participated to measure the glucose concentration on the finger ($G_F$) and the forearm ($G_A$) with a portable glucometer under overnight fasting state. Then, the venous glucose concentration ($G_V$) was measured in 514 subjects in less than 1 hour. The test results were analyzed by simple linear regression, intraclass correlation, and Passing-Bablok regression techniques. $G_A$ was highly correlated with $G_F$ or $G_V$ showing the correlation coefficients (r) of approximately 0.97 (P<0.0001) in the normal group. The patient group also resulted similarly high correlation with only slightly lower r value. The mean differences in glucose concentration were less than ${\pm}10mg/dL$ regardless of the sampling sites. Intraclass correlation coefficients were slightly smaller than r but very much similar in value in both groups. The 95% confidence intervals of the slope as well as the intercept in the Passing-Bablok regression analysis were < ${\pm}20%$ and < ${\pm}20mg/dL$, respectively, which were within the clinically acceptable ranges. These three statistical techniques introduced in the present study well demonstrated the consistency of $G_A$ with $G_F$ and $G_V$. Therefore, the forearm blood glucose test could be considered as clinically valid under fasting condition.

The purpose of this study was to develop a web-based internet program for nutritional counseling and diet management of patient with diabetes mellitus. The program consisted of four parts according to their functions and contents. The first part explained the metabolism of glucose and mechanism of insulin and insulin receptor expressed by flash 6.0, and defined the diabetes mellitus. The second part is to assess the general health status such as body weight, obesity index, basal metabolic rate and total energy requirement by the input of age, sex, height, weight and degree of activity. This part also provides tlne patient with menu lists and one day menu suitable to his weight and activity, and offers the information for food selection, snacks, convenience foods, dine-out, behavioral modification, cooking methods, food exchange lists, dietary education using buffet, and information on energy and nutrients of foods and drinks, and top 20 foods classified by nutrients. The third part is designed to investigate dietary history of patient, that is, to find out his inappropriate dietary habit and give him some suggestions for appropriate dietary behavior. This part also offers on-line counseling, follow-up management and frequently asked questions. The fourth part is evaluating their energy and nutrients intake by comparing with recommended dietary allowance for Koreans or standardized data for patient with diabetes mellitus. In this part, it is also analyzing energy and nutrients of food consumed by food group and meals, and evaluating the status of nutrient intake. These results are finally displayed as tabular forms and graphical forms on the computer screen. Therefore it is expected that the web-based internet program developed in this study will play a role in their health promotion as widely using by diabetic patients.

This study was designed to observe the effects of the feeding Platycodon grandiflorum(6 or 22 years) extract on the improvement of the blood glucose, lipids in the serum and liver of alloxaninduced hyperglycemic rats(S.D. strain, ♂), alloxan monohydrate 15mg/kg B.W./day I.P. injection) for 3 weeks. Concentrations of blood glucose were significantly higher in the alloxan administration(I.P.) groups(groups 2, 3 and 4) than those in the control group(group 1, basal diet). Blood glucose concentrations were remarkably lower in the group 3(basa1+alloxan+6years Platycodon grandiflorum) and 4(basa1+alloxan+22years Platycodon grandiflorum) than those in the group 2(basal+alloxan), and particularly, lower in the group 4. Concentrations of total cholesterol and LDL-cholesterol in serum were significantly lower in the groups 3, 4 than those in the group 2, and remarkably, lower in the group 4 than those in the group 3. Concentrations of HDL-cholesterol in serum were tile highest in the group 1. Those in the groups 3 and 4 were higher than those in the group 2. Atherosclerotic index were lower in the group 3, 4 than those in the group 2. In the alloxan-induced diabetic groups(groups 2, 3, 4), the serum free cholesterol, cholesterol ester, triglyceride and phospholipid concentrations were significantly lower in the group 3, 4 than those in the group 2. Contents of total cholesterol, triglyceride and phospholipid in liver were remarkably lower in the all experimental groups than those in the group 2. The activities of aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase In serum were the highest in the group 2, but the other groups were rather lower. From the above research, the Platycodon grandiflorum(6 or 22 years) extracts were effective on the improvement of the blood glucose, lipid compositions in serum and liver. And particularly, Platycodon grandiflorum(22 years) was more effective than those in the Platycodon grandiflorum(6 years).

The purpose of this study was to investigate the effect of Acanthopanax senticosus extract (ASE) (ethanol : DW=1:1, v/v) on inhibition of type 2 diabetes using an OLETF rat model via regulation of HbA1c and AGEs levels. Supplementation with ASE 0.1% and 0.5% effectively lowered levels of glucose, insulin, oral glucose tolerance test, and Homa-insulin resistance, suggesting reduced insulin resistance. Blood levels of HbA1c and AGEs were significantly reduced in a dose-dependent manner. As oxidative stress plays a key role in accelerating production of HbA1c and AGEs, which worsen symptoms of type 2 diabetes, levels of malonaldehyde and pro-inflammatory cytokines were measured. Lipid peroxidation in both blood and liver tissues was significantly reduced, and induction of pro-inflammatory cytokines interleukin-${\beta}$ and tumor necrosis factor-${\alpha}$, which elevate production of HbA1c and AGEs, was inhibited (P<0.05). To evaluate the possible cellular events after AGEs receptor activation, genetic expression of protein kinase C (PKC)-${\delta}$ and transforming growth factor (TGF)-${\beta}$ was measured by real-time polymerase chain reaction. Supplementation with both ASE 0.1% and 0.5% significantly inhibited mRNA expression of PKC-${\delta}$ and TGF-${\beta}$, indicating that ASE may have beneficial effects on preventing insulin-resistant cells or tissues from progressing to diabetic complications. Taken together, ASE has potential to improve type 2 diabetes by inhibiting insulin resistance and protein glycosylation, including production of HbA1c and AGEs. Anti-oxidative activities of ASE are a main requisite for reducing production of HbA1c and AGEs and are also related to regulation of the PKC signaling pathway, resulting in suppression of TGF-${\beta}$, which increases synthesis of collagen, prostaglandin, and disease-related proteins.

A considerable change of the Korean nursing system has been made during the last decade not only in its philosophy but also in its function and structure to meet political and scientific need of the modern society. The main purpose of this study is to develope the new concept of comprehensive nursing care, both its Philosophy and ethics, as the basic of modern clinical nursing theory and practice. Comprehensive nursing care is the concept of human centered nursing care, and it helps a man to meet the basic physical, psychological, environmental, socioeconomic and teaching needs. It also helps him to help himself to meet these needs. This concept starts from the individualized nursing care and its ultimate goal is to improve a man to have a better position in his own community so that he may able to have a meaningful life. To accomplish this goal, an individualized nursing care plan as a nursing diagnosis and problem solving method should be set up for different patients with similar diagnosis to meet their needs, because each patient has a different social background. from this viewpoint, nursing is a science as well as abstruse humanity. The performance of comprehensive nursing care is a goal and issue of modern clinical nursing care. If nursing is a science and a profession for man, it should have ethics which recognize the dignity of man and offers infinite service voluntarily, and should be able to show leadership in carrying out the nursing responsibility. This leadership finds a person's potential and encourages him to utilize it. Such concepts should develop into a nursing ideology and this ideology should become a priority in comprehensive nursing care. The following statements are the conclusion of this study. 1) Modern nursing has been developed from disease centered nursing care to comprehensive nursing care based on humanity. The primary principle of nursing was to assist in the treatment of disease, but it has been changed to the professional nursing system independently. 2) The concept of nursing is one of continuous or endless scope of dispersion. It proves that nursing is grasping the professional responsibility to be able to coordinate scientific principles Patient health problems are according to scientific principles rather than adhering to nursing technical discipline as a daily work. 3) In chapter I and Ⅱ, the philosophy and ideology of nursing have been discussed and the flow of concept of clinical nursing and the rate of progress which emerges from naturalizing performance of the concept of comprehensive nursing in clinical nursing studied. The discussion developed the theory that a nurse should be to embody nursing ideas and objectives by establishing definite conviction of professions and study. 4) In chapter lil, nursing planning based on nursing diagnosis as a method to attain ideal nursing care for humanity with a definite idea of establishing philosophy of nursing was presented. 5) From the result of survey on patient needs about treatment and nursing, it was observed that all patient had emotional stress from unknown factors. Therefore it was concluded that nurses should not only educate the patient but also give them the opportunity to communicate freely their needs and anxieties. Furthermore complaints and doubts of the patient should be carefully noted and must be considered to meet these needs. 6) Patient teaching is the most important part of comprehensive nursing care. In chapter, Ⅲ, the important of patient teaching was emphasized by demonstrating the effect of patient teaching for diabetic patient. 7) In Chapter Ⅳ, from the result of the study on nurses attitudes to comprehensive nursing care, it was pointed that the evolution of nursing education and the establishment of a complete concept and value of comprehensive nursing was necessary.

It was reported that the novel compounds (LP9M80-H) of $Liriope$ $platyphylla$ regulate glucose transporter (Glut) biosynthesis by activating the insulin-signaling pathway in the liver and brain of ICR mice. To investigate the therapeutic effects of LP9M80-H on the pathology of diabetes and obesity, alterations of key factors related to symptoms were analyzed in the Otsuka Long Evans Tokushima Fatty (OLETF) rats treated with LP9M80-H for 2 weeks. The abdominal fat masses in the LP9M80-H-treated group were lower than the vehicle-treated group, although there was no difference in body weight between the two groups. Additionally, when compared to the vehicle-treated group, LP9M80-H treatment induced a significant decrease in glucose levels and an increase in the insulin concentration in the blood of OLETF rats. A high level of insulin protein was also detected in pancreatic ${\beta}$ cells of LP9M80-H-treated OLETF rats. A significant reduction in the concentration of lipids and adiponectin was detected only in LP9M80-H-treated OLETF rats. Furthermore, the expression of insulin receptor ${\beta}$ and the insulin receptor substrate (IRS) was dramatically decreased in LP9M80-H-treated OLETF rats compared to the vehicle-treated group. Of the glucose transporters located downstream of the insulin-signaling pathway, glucose transporters (Glut) -2 and -3 were significantly decreased in LP9M80-H-treated OLETF rats, while the level of Glut-4 was maintained under all conditions. Therefore, these results suggest that LP9M80-H may contribute to relieving symptoms of diabetes and obesity through glucose homeostasis and regulation of lipid concentration.

Background: Plasminogen activator inhibitor-1(PAI-1) is known as the primary physiological inhibitor of tissue-type plasminogen activator(t-PA) in the plasma, and is present within the atherosclerotic vessels. Increased plasma levels of PAI-1 are one of the major disturbances of the hemostatic system in patients with diabetes and/or hypertension, and may have multiple interrelations with the important risk factors in the development of atherosclerosis. This study was performed to determine whether altered gene expression of PAI-1 occurs within the arterial wall, and thereby potentially contributing to the increase of cardiovascular risks associated with diabetes and/or hypertension. Material and Method: The aortic vascular smooth muscle cells of the rat were exposed to 22 mM glucose, angiotensin II, and insulin increased PAI-1 mRNA expression with the use of Northern blotting were examined. Also examined were the effects of 22 mM glucose, angiotensin II and insulin on the growth of the rat's aortic smooth muscle cells by using MTT assay. Result: Twenty-two mM glucose treatment increased the PAI-1 mRNA expression in a time- and dose-dependent manner. Aniotensin II treatment synergistically increased the glucose-induced PAI-1 mRNA expression. In contrast, addition of insulin attenuated the increase of 22 mM glucose and angiotensin II induced PAI-1 mRNA expression. Furthermore, treatment of 22 mM glucose, angiotensin II and insulin resulted in a significant increase in cell numbers. This study demonstrated that 22 mM glucose and angiotensin II have a synergistic effect in stimulating the PAI-1 mRNA expression and in the cell growth of the rat's aortic smooth muscle cells. Conclusion: Elevation of glucose and angiotensin II may be important risk factors in impairing fibrinolysis and developing atherosclerosis in diabetic patients.

As a natural plant ingredients, glasswort (Salicornia herbacea L.) contains various physiological activities, mainly anti-oxidative and anti-diabetic activities. However, only a few studies have been carried out on its anti-adipogenic effect. This study investigated the anti-obesity effects of Salicornia herbacea L. on 3T3-L1 adipocytes. As adipogenesis of preadipocytes to adipocytes involves proliferation and differentiation of cells, we treated three concentrations (125, 250, and $500{\mu}g/mL$) of Salicornia herbacea L. water extracts (SLW) in both pre-processing and post-processing stages. When 3T3-L1 adipocytes were differentiated and dyed with Oil Red O, adipocytes size and the value of relative Oil Red O staining were reduced by all concentrations of SLW in post-processing stage. Following adipogenic differentiation, the concentration of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in the cell supernatant significantly increased upon treatment with $125{\mu}g/mL$ of SLW and further rose at concentrations of 250 and $500{\mu}g/mL$ during post-processing stage. There was no significant difference in glycerol production upon SLW treatment. Leptin production significantly decreased at all SLW concentrations during post-processing stage, whereas peroxisome proliferator activated receptor-${\gamma}$ (PPAR-${\gamma}$) and adiponectin secretions were significantly enhanced. Overall results showed that SLW might have an anti-adipogenic effect via enhancement of TNF-${\alpha}$ production, which causes dedifferentiation and inhibits lipid accumulations in adipocyte. Furthermore, SLW might prevent diabetes and cardiovascular disease, as it reduces leptin secretion and enhances production of both PPAR-${\gamma}$ and adiponectin. However, further research is needed to elucidate the exact mechanism and bioactive compounds of glasswort.

This study was performed to investigate the hypoglycemic effect of pine needle extract oil against type 2 diabetes. Six-week-old male C57BL/Ks(db/db) mice were divided into four groups : negative control, pine needle extract oil low dose, high dose and positive control groups, which fed daily for 6 weeks with corn oil, pine needle extract oil 112.5 mg/kg, 450 mg/kg or metformin (150 mg/kg ), respectively. The oral administration of the pine needle extract oil resulted in the significant and dose-dependent decreases of blood glucose levels in comparison with corn oil treatment. The levels of HbAlc showed a tendency of the decrease by the high dose treatment of the pine needle extract oil and were positively correlated with blood glucose levels (r=0.5046, p=0.0023) . However, the levels of serum insulin and C-peptide were not affected by pine needle extract oil or metformin treatments. The levels of serum leptin, which is related with the insulin sensitivity, showed a tendency of the increases by pine needle extract oil treatment and were negatively correlated to blood glucose levels (r=-0.4754, p=0.0052). In conclusion, these results suggest that the pine needle extract oil have a potential for the oral anti-hyperglycemic agent and the mode of action may be related with the improvement of the insulin sensitivity through blood leptin.
