Background : To evaluate the clinical characteristics of lung cancer patients in Korea, where there is a higher number of smokers than in Western countries. Methods : A retrospective study was performed on 1655 lung cancer patients, who were diagnosed at a university hospital between September 1996 and August 2005. Age, gender, cell types and clinical stage were analysed. Of 941 patients, who responded to a questionnaire at the time of diagnosis, the smoking habits, occupational history, family history of lung cancer in the first-degree relatives, coexisting diseases (diabetes mellitus and cardiovascular disease), body weight loss, ECOG performance status and presenting symptoms, were examined prospectively. In addition, coexisting diseases including chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis and active pulmonary tuberculosis were evaluated. Results : Of the 1655 patients, the male to females ratio was 3.6. Squamous cell carcinoma was the most common cancer whereas adenocarcinoma was more common in lifetime nonsmokers or women. 19.9% of the patients were non smokers and 80.1% ever smokers. Since 2000, there was an increase in the incidence of adenocarcinoma with a corresponding decrease in the incidence of squamous cell carcinoma. 6.2% of patients were asymptomatic. A coincident diagnosis of chronic obstructive pulmonary disease, cardiovascular disease, diabetes mellitus, active pulmonary tuberculosis, and idiopathic pulmonary fibrosis was made in: 44.1%, 22.2%, 10.7%, 3.9%, and 1.6% of patients, respectively. A positive family history of lung cancer in the first-degree relatives was identified in 4.4% of patients. An occupational history relevant to lung cancer was identified in 12.2% of patients. Conclusion : There is a high proportion of cigarette smokers in Korean lung cancer patients. The most common cell type was squamous cell carcinoma. However, a more detailed, prospective study of the clinical characteristics will be needed to better characterize lung cancer in Korea.

This study was carried out to investigate the effects of nutrition education on blood glucose in type 2 diabetic patients with low income. There were 50 (27 male and 23 female) study subjects with type 2 diabetes under national medical support, and the monthly income in most of them was less than 500,000 won. Anthropometric measurement, biochemical blood indices, food intake, dietary habits, and nutrition knowledge of the subjects were investigated before nutrition education. Nutrition education was conducted 6 times within 12 weeks. After nutrition education, the glycosylated hemoglobin was significantly decreased (male: $8.4{\pm}1.6%$ to $8.0{\pm}1.7%$, female: $8.3{\pm}1.6%$ to $8.0{\pm}1.3%$) and the total cholesterol was also significantly decreased in both groups. The group of female resulted in a significant decrease in fasting blood glucose ($169.7{\pm}28.2$ mg/dL to $152.8{\pm}22.0$ mg/dL) and triglyceride ($177.8{\pm}56.3$ mg/dL to $162.3{\pm}36.1$ mg/dL), but the group of male did not show a significant decrease in fasting blood glucose and triglyceride. Nutritional knowledge and dietary habit scores of the subjects were significantly improved after nutrition education. The results demonstrate that nutrition education for type 2 diabetic patients with low income are effective in improving their blood glucose.

With the purpose of identifying significant risk factors in poststernotomy sternal wound infection and mediastinitis, we underwent a retrospective analysis of the whole patients operated on at the our department of cardiovascular surgery for the two years. Material and Method: From March 200f to March 2003 at the depart-ment of cardiovascular surgery, medical school of Soonchunhyang University, major sternal wound infections had been developed in 12 (9.76%) of 123 consecutive patients. These patients underwent open-heart procedure through a midline sternotomy and survived long enough for infection to appear. For this group of patients, we evaluated possible risk factors such as age, sex, diabetes mellitus, chronic obstructive pulmonary disease, obesity, interval between hospital admission and operation, type of surgical procedure, elective or emergency surgical procedure, reoperation, duration of surgical procedures, duration of cardiopulmonary bypass, amount of blood transfused, post-operative blood loss, chest reexploration, rewiring of a sterile sternal dehiscence, duration of mechanical ventilation, and days of stay in the intensive care unit and analyzed these factors. Result: Analysis represented that age, sex, diabetes mellitus, type and mode of surgical procedure, reoperation, duration of operation, duration of cardio-pulmonary bypass, and interval between hospital admission and operation were not significantly associated with wound infection. For all other predisposing factors, p-values of less than .05 were demonstrated. Eight emerged as significant: early chest reexploration (p=0.001), sternal rewiring (p< 0.0001), chronic obstructive pulmonary disease (p<0.0001), blood transfusions (p<0.05), postoperative bleeding (p=0.008), days of stay in the intensive care unit (p< 0.0001), duration of mechanical ventilation (p=0.001), and obesity (p=.003). Conclusion: Contamination of pa-tients may occur before, during, and after the operation, and any kind of reintervention may predispose the patient to wound infection.

Objectives : The surgical results of 80 patients with growth hormone(GH)-producing pituitary adenoma were analyzed retrospectively to evaluate the clinical manifestations and to determine which preoperative factors significantly influenced the surgical outcome. Patients and Methods : The patients consisted of 39 men and 41 women and the age of patients at the time of initial operation ranged from 17 to 67 years(mean age, 40.5 years) Between January 1990 and June 1996, 77 patients underwent transsphenoidal surgery and 3 patients underwent craniotomy for GH-producing pituitary adenoma at our institution. Preoperative administration of octreotide was performed in 18 patients. Surgical control was defined as a postoperative serum basal level of GH less than 5ng/ml. A logistic regression model was used for univariate and multivariate analysis. Probability value of less than 0.05 was considered as statistically significant. Results : The most common presenting symptom was acromegaly, followed by headache, visual disturbance, and fatigability. Visual symptoms were present in 39% of the patients. Diabetes mellitus was associated in 24 patients and hypertension in 12. Preoperative mean basal level of GH was 93.2ng/ml(range 72-500ng/ml) which was closely related with tumor size(p<0.05). Grade II by Hardy's classification was the most common radiological type. Preoperative octreotide treatment significantly reduced the level of GH(p<0.05), but not enough to induce endocrinological remission. One patient died of cerebral infarction after craniotomy. The most common surgical complication was transient diabetes insipidus. The symptom of the earliest improvement after surgery was paresthesia and tightness of the hand and foot, followed by headache and easy fatigability. The preoperative visual symptom was improved in all patients. The patients who had hypertension or DM experienced alleviated symptoms in 67% and 92%, respectively. The overall rate of endocrinological remission was 44%. By multivariate logistic regression analysis, the size of tumor, extrasellar extension, and extent of removal were significant prognostic factors for endocrinologial remission. Conclusion : Early detection of a small tumor without extrasellar extension followed by a complete resection is highly recommended in order to achieve endocrinological cure of GH-producing pituitary adenomas.

Until now there are few available epidemiologic data of osteoporosis in Korea, and the severity of osteoporosis-related health problem has not been widely recognized yet. But the numbers of the old people are increasing in Korea, and in 2000, the proportion of people over 65 will be up to about 6.8% of total population. Therefore, osteoporosis, one of the most common metabolic bone disease among the old people, will be one of the most important public health problem. On this background this study was performed to find out risk factors of the development of osteoporosis in Korean women through case-control approach. The subject of this study were selected among the women who visited menopause clinic in one general hospital in Seoul and were checked bone density from Sep. 1988 to Sep. 1993. Those who were diagnosed to have hypertension, diabetes mellitus, thyroid disease, breast disease, or liver disease, which are thought to influnce bone density, were excluded. Also excluded those who are age-unknown. Finally the subjects were 2,139 women aged between 18 and 79. We operatively defined patient group as those whose bone density is below $1.039/cm^2$, 90% of average bone density of women of 4th decade who visited the same hospital. And we defined control group as whose bone dendity is above $1.15g/cm^2$. We randomly selected 201 women from the patient group and 202 from the control. As independent variables we chose age, menarche age, menopause age, menopause type, the number of siblings, the number of pregnancies, body mass index, taking oral pill or not, feeding type, and educational state. Multiple logistic regression analysis was done to see the influence of these variables on the risk of osteoporosis. Results are as follows; 1. menopausal status was statistically significant risk factor to all women irrespective of her age, while obesity and later menopause age were found to be statistically significant protective factors. 2. The more siblings and pregnancies, the greater tile risk of osteoporosis, but these factors were not statistically significant. This result is not consistent with other studies. Further studies are strongly needed.

Background: Dysregulation of hepatic glucose production (HGP) contributes to the development of type 2 diabetes mellitus. Telmisartan, an angiotensin II type 1 receptor blocker (ARB), has various ancillary effects in addition to common blood pressure-lowering effects. The effects and mechanism of telmisartan on HGP have not been fully elucidated and, therefore, we investigated these phenomena in hyperglycemic HepG2 cells and high-fat diet (HFD)-fed mice. Methods: Glucose production and glucose uptake were measured in HepG2 cells. Expression levels of phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase ${\alpha}$ ($G6Pase-{\alpha}$), and phosphorylation levels of insulin receptor substrate-1 (IRS-1) and protein kinase C ${\zeta}$ ($PKC{\zeta}$) were assessed by western blot analysis. Animal studies were performed using HFD-fed mice. Results: Telmisartan dose-dependently increased HGP, and PEPCK expression was minimally increased at a $40{\mu}M$ concentration without a change in $G6Pase-{\alpha}$ expression. In contrast, telmisartan increased phosphorylation of IRS-1 at Ser302 ($p-IRS-1-Ser^{302}$) and decreased $p-IRS-1-Tyr^{632}$ dose-dependently. Telmisartan dose-dependently increased $p-PKC{\zeta}-Thr^{410}$ which is known to reduce insulin action by inducing IRS-1 serine phosphorylation. Ectopic expression of dominant-negative $PKC{\zeta}$ significantly attenuated telmisartan-induced HGP and $p-IRS-1-Ser^{302}$ and -inhibited $p-IRS-1-Tyr^{632}$. Among ARBs, including losartan and fimasartan, only telmisartan changed IRS-1 phosphorylation and pretreatment with GW9662, a specific and irreversible peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$) antagonist, did not alter this effect. Finally, in the livers from HFD-fed mice, telmisartan increased $p-IRS-1-Ser^{302}$ and decreased $p-IRS-1-Tyr^{632}$, which was accompanied by an increase in $p-PKC{\zeta}-Thr^{410}$. Conclusion: These results suggest that telmisartan increases HGP by inducing $p-PKC{\zeta}-Thr^{410}$ that increases $p-IRS-1-Ser^{302}$ and decreases $p-IRS-1-Tyr^{632}$ in a $PPAR{\gamma}$-independent manner

The anti-diabetic effects of Allium tuberosum Rottler extracts (ATE) and ATE fermented with lactic acid bacteria in db/db mice were evaluated. The electron donating activity of ATE fermented with Lactobacillus plantarum, and Lactobacillus casei, respectively, increased compared to that of ATE, but the superoxide radical scavenging activity of the ATE incubated with L. plantarum decreased. The superoxide radical scavenging activity of the ATE fermented with both L. plantarum and L. casei was similar to that of the ATE. Therefore, fermented ATE (FATE) was prepared for in vivo testing by incubating it with both L. plantarum and L. casei. The db/db mice were divided into six groups: normal (non-diabetic mice), diabetic control (DM), and four experimental groups administered 200 or 400 mg/kg/day ATE (ATE200 and ATE400) and 200 or 400 mg/kg/day FATE (FATE200 and FATE400). Weight gain was significantly inhibited in the FATE200 group compared with that in the other db/db mice groups (p<0.05). The areas under the curve of the ATE400 and FATE400 groups were significantly smaller than that of the DM group in the glucose tolerance evaluation. The serum glucagon-like peptide-1 levels in the ATE400 and FATE400 groups increased. These results indicate that administering ATE and FATE may be effective against anti-hyperglycemia by regulating insulin resistance. In particular, FATE may be beneficial for controlling obesity in type 2 diabetes.

Saturated fatty acids contribute to β-cell dysfunction in the onset of type 2 diabetes mellitus. Cellular responses to lipotoxicity include oxidative stress, endoplasmic reticulum (ER) stress, and blockage of autophagy. Palmitate induces ER Ca²⁺ depletion followed by notable store-operated Ca²⁺ entry. Subsequent elevation of cytosolic Ca²⁺ can activate undesirable signaling pathways culminating in cell death. Mitochondrial Ca²⁺ uniporter (MCU) is the major route for Ca²⁺ uptake into the matrix and couples metabolism with insulin secretion. However, it has been unclear whether mitochondrial Ca²⁺ uptake plays a protective role or contributes to lipotoxicity. Here, we observed palmitate upregulated MCU protein expression in a mouse clonal β-cell, MIN6, under normal glucose, but not high glucose medium. Palmitate elevated baseline cytosolic Ca²⁺ concentration ([Ca²⁺]_i) and reduced depolarization-triggered Ca²⁺ influx likely due to the inactivation of voltage-gated Ca²⁺ channels (VGCCs). Targeted reduction of MCU expression using RNA interference abolished mitochondrial superoxide production but exacerbated palmitate-induced [Ca²⁺]_i overload. Consequently, MCU knockdown aggravated blockage of autophagic degradation. In contrast, co-treatment with verapamil, a VGCC inhibitor, prevented palmitate-induced basal [Ca²⁺]_i elevation and defective [Ca²⁺]_i transients. Extracellular Ca²⁺ chelation as well as VGCC inhibitors effectively rescued autophagy defects and cytotoxicity. These observations suggest enhanced mitochondrial Ca²⁺ uptake via MCU upregulation is a mechanism by which pancreatic β-cells are able to alleviate cytosolic Ca²⁺ overload and its detrimental consequences.

This is descriptive study to 2nd analysis data KNHANES IV-VI about risk factors of readmission among patients with cardiovascular disease. Among the total 65,973 adults, 1,037 with angina or myocardial infarction were analyzed. The analysis was conducted using SPSS window 21 Program and CHAID decision tree was used in the classification analysis. Root nodes are economic activity(χ²=12.063, p=.001), children's nodes are personal income(χ²=6.575, p=.031), weight change(χ²=12.758, p=.001), residential area(χ²=4.025, p=.045), direct smoking(χ²=3.884, p=.031). p=.049), level of education(χ²=9.630, p=.024). Terminal nodes are hypertension(χ²=3.854, p=.050), diabetes mellitus(χ²=6.056, p=.014), occupation type(χ²=7.799, p=.037). We suggest that the development and operation of programs considering the integrated approach of various factors is necessary for the readmission management of cardiovascular patients.
