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.

Studies were carried out to observe the influence of the Aralia continentalis Kitagawa root on blood pressure and blood constituents of the 24 hypertensive elderly(10 men and 14 women aged over 60). Total subjects were divided into three groups according to taking antihypertensive medications(A), antihypertensive medications and mixing beverages with the Aralia continentalis Kitagawa root(B) or mixing beverages with Aralia continentalis Kitagawa root(C). The systolic blood pressure of C group was significantly lower than that of A and B groups. The diastolic blood pressure of C group was lower than A and B groups. The blood glucose level of C group was a little lower than that of A and B groups. The level of TG increased more in A group than C group and decreased in B group. The levels of T-cholesterol and LDL-cholesterol lowered in B and C groups and HDL-cholesterol level was higher in C group. The GOT, GPT and T-bilirubin levels of C group were significantly higher than others. Mixing beverages with Aralia continentalis Kitagawa root did not affect on blood protein and non-protein nitrogens. In conclusion, mixing beverages with Aralia continentalis Kitagawa root had an effect on lowering blood pressure, blood glucose, T-cholesterol and LDL-cholesterol concentrations.

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.

A series of 25 patients with residual, recurrent, and unresectable gastric cancer received various combination of surgery, radiotherapy (RT), chemotherapy (CT), and hyperthermia (HT). They were placed into 7 categories; 1) CT and HT-14 patients; 2) RT and HT-15 patients; 3) surgery, RT and HT-2 patients; 4) surgery, RT, HT and CT-1 patient; 5) RT, HT and CT -1 patient; 6) RT and CT-1 patient; 7) RT alone-1 patient. Three patients had curative resection. 21 patients received irradiation with tightly contoured portals to spare as much small bowel, kidney and marrow as possible. Hyperthermia was applied regionally once or twice a week for 23 patients using 8 MHz radiofrequency capacitive heating device (Thermotron RF-8). HT was given approximately 30 min after RT 7 patients were treated with CT: 4 patients received HT and concomitant Mitomycin-C; 3 patients received HT and sequential 5-FU+Adriamycin+Mitomycin-C. There was not any treatment related deaths. There was also no evidence of treatment related problems with liver, kidney, stomach, or spinal cord except only one case of transient diabetic ketoacidosis. The tumor response was evaluable in 22 patients. None achieved complete remission.11 ($50\%$) achieved partial remission. The response rate was correlated with total radiation dose and achieved maximum temperature. 9 of 14 ($64\%$) received more than 4000 cGy showed partial remission; especially, all 3 patients received more than 5500 cGy achieved partial response.8 of the 12 patients ($67\%$) who achieved maximal temperature more than $41^{\circ}C$ showed partial response in comparing with $25\%$ (2 of 8 patients, below $41^{\circ}C$). The numbers of HT, however, was not correlated with the response. 3 of the 25 patients ($12\%$) remain alive. The one who was surgically unresectable and underwent irradiation alone is in progression of the disease with distant metastases. The remaining two patients with curative resection are alive with free of disease, 24 and 35 months, respectively. The median survival by response are 11.5 months in responders and 4.6 months in non-responders.

Artemisia capillaries THUNB is a perennial herb that belongs to the family compositae spp. and the most common plant among the various herbal folk remedies used in treatment of abdominal pain, hepatitis, chronic liver disease, jaundice and coughing in Korea. The object of this study is to observe the dosage-dependent anti-obestic effects of an aqueous extracts of dried aqueous extracts of stems of Artemisia capillaris Thunberg. [Artemisiae capillaris Herba, In-Jin in Korean, INJ] on 45%/Kcal high fat diet (HFD) supplied mice. 45%/Kcal rodent HFD are supplied to ICR mice from 1 week before initiation of INJ administration throughout the 12 weeks, and after the end of 12 weeks of 62.5, 125 and 250 mg/kg/day of INJ administration, the efficacy was divided into five categories 1) hypoglycemic, 2) hepato-protective, 3) nephroprotective, 4) hypolipemic, and 5) anti- obesity effects. The effects were compared to those of simvastatin (for hypolipemic activity), silymarin (for hepatoprotective and free radical scavenger effects) and metformin (for hypoglycemic and related anti-obesity effects). 7 animals per group (8 groups; total 56adapted mice on HFD were selected base on the body weight at 6 days after initiation of HFD supply) were used in this experiment. INJ and all three different reference drugs were directly suspended or dissolved in distilled water, and administered at a volume of 10 mL/kg, once a day for 84 days from 1 week after HFD supply. As results of 91 days of continuous HFD supply, mice showed marked obese states, hyperglycemia, hyperlipemia, liver damages and kidney damages. These mean the obesity, diabetes, diabetic hepatopathies, nephropathies and hyperlipemia were induced by HFD supply. After end of 84 days of continuous treatment of three different dosages of INJ, all diabetes related complications were inhibited; relatively favorable anti-obesity, hypolipemic, hepatoprotective, hypoglycemic and nephroprotective effects. These favorable effects showed relatively good dose-relations between all three different dosages of INJ treated, and INJ 250 mg/kg showed enough favorable effects on diabetes and related four complications tested as compared with one of each three different references. Otherwise, the efficacy of 62.5 and 125 mg/kg of INJ was somewhat slighter than those of all three reference drugs. Therefore, the suitable effective dosage of INJ is considered as 250 mg/kg/day in the present study. The overall anti-obesity effects of INJ 250 mg/kg-treated group was similar or more favorable than those of metformin 250 mg/kg-treated group, and INJ 250 mg/kg showed slighter hypoglycemic effects with silymarin 100 mg/kg and metformin 250 mg/kg, similar hypolipemic effects with simvastatin 10 mg/kg, and similar hepatoprotective effects with silymarin 100 mg/kg, and similar nephroprotective effects with that of silymarin 100 mg/kg and metformin 250 mg/kg, respectively. Obese, hyperglycemia, hyperlipemia, steatohepatitis and related nephropathies induced by HFD supply were dramatically inhibited by 84 days of continuous treatment of all three different dosages of INJ. It is, therefore expected that INJ extracts will be a favorable alternative agent for diet-related diabetes and complications.

Hypericum ascyron has long been used as medicinal plant and recent studies reported that H. ascyron has anti-diabetic, anti-oxidant, and anti-bacterial effects. In this study, inhibitory effect from H. ascyron on pro-inflammatory responses has been investigated. H. ascyron was extracted at optimal extraction condition. Total phenolic contents in water and 90% ethanol were 29.75 and 31.82 mg/g, respectively. Hyaluronidase inhibitory activity of H. ascyron extracts ($50-200{\mu}g/mL$ phenolics) was 0.00-14.81% and 15.33-47.49%, respectively. In cell viability, cell toxicity was shown at concentration of $100{\mu}g/mL$ and $30{\mu}g/mL$ of water and 90% ethanol extract. Therefore, $10-50{\mu}g/mL$ in water extracts and $5-20{\mu}g/mL$ in ethanol extracts was selected each for further study. Inducible nitric oxide synthase (iNOS) derived nitric oxide (NO) and cyclooxygenase (COX)-2-derived prostaglandin $E_2$ ($PGE_2$) protein expression inhibitory effect of extracts were inhibited in a dose dependent manner, significantly. Also, the pro-inflammatory cytokines inhibitory effect such as tumor necrosis $factor-{\alpha}$, nterleukin (IL)-6 and $IL-1{\beta}$ were decreased in the dose dependent manner. The results indicate that H. ascyron extracts reduced inflammatory responses in lipopolysaccharide-induced 264.7 cells via the regulation of the iNOS, COX-2, NO, $PGE_2$, and pro-inflammatory cytokines. Therefore, H. ascyron extracts have significant anti-inflammatory effect and a source as therapeutic materials.

The tea has traditionally been used as a foodstuff by unique flavor, however recently not only the diversity of consumer demands but also the public interest in unique favorite and functional aspects have increased. It has been also reported that the main components contained in the leaves of tea (Camellia sinensis) include total nitrogen, free amino acids, polyphenols, and fiber, of which catechin has powerful bioactive effect such as anti-cancer, anti-aging, and anti-diabetic. (-)-Epigallocatechin gallate (EGCG) which is a major phenolic constituent of green tea extract has received considerable attention for a variety of important bioactivities. This study was carried out to obtain useful information for tea breeding programs, and to investigate the concentration of quality and functional related components in Korean indigenous tea germplasms. Korean indigenous tea lines were classified into three groups of sprout time, i.e, early, medium and late sprout time, and the ratio were 20%, 43% and 37%, respectively. There was a difference in characteristics among these Korean indigenous tea lines, leaf width of those ranged from 19.8 to 75 mm, leaf length was 35.5-160.0 mm, and leaf area was $660-8,400\;mm^2$. Experimental data on chlorophyll content (SPAD value) of Korean indigenous tea genetic resources ranged from 51.3 to 82.3. The concentrations of the total nitrogen, total free amino acids, and theanine were ranged 4.18-6.07%, 2.87-4.58%, and 1.64-2.66%, respectively. Also, catechin concentration showed from 11.54 to 15.07%, and concentration of caffeine was 2.82-4.23%. These results indicated indicated that it is possible to select elite lines with high concentration of quality related components and low concentration of caffeine from Korean domestic tea germplasms.
