Purpose: The lower extremity edema (LEE) is a common distressful symptom in advanced cancer patients and is hard to manage. We analyze the characteristics of LEE in patients with advanced cancer to provide the basic information of causes and adequate management. Methods: Physical examination, assessment of the location and severity of edema, blood chemistry (albumin, creatinine), Doppler Sono for patients with suspecting deep vein thrombosis (DVT), and abdomen CT scan for patient with suspecting lymph edema were performed. Severity of edema was classified according to NCI lymph edema scaling and improvement was defined as lowering at least 1 grade of edema after management. Results: Among 154 patient who had been admitted to Hospice Ward from Mar 2003 to Jan 2004, 33 had LEE, and 6 had both upper extremity edema and LEE except generalized edema. Their underlying cancers were stomach (7), lung (6), biliary tract (5), liver (5), colorectal (5), pancreas (2), and others (9). There were 12 patient with grade I, 20 patients with grade II, and 7 patients with grade III edema. The causes were hypoalbuminemia (11), lymph edema (10), DVT (7), obstruction of inferior vena cava (IVC) or portal vein (6), and dependent edema (5). The common managements were including leg elevation and diuretics. Elastic stocking was applied for patients with DVT and leg massage and pneumatic compression was used for lymph edema. The 2/3 patients were improved after management. Conclusion: The incidence of LEE in terminal cancer pts was high (25.3%) and their causes were variable including lymph edema, DVT, hypoalbuminemia and dependent edema. Active noninvasive management according to causes could result in good palliation.

This study was conducted to investigate the effects of dietary resveratrol on growth performance, blood biochemical parameters, immunoglobulin, and blood antioxidant activity in broiler chicks. Three hundred twenty one-day old broiler chicks were divided 8 treatments (C(-), basal diet; C(+), basal diet with antibiotics; DL-${\alpha}$-tocopherol 20 IU; DL-${\alpha}$-tocopherol 200 IU; resveratrol 20 ppm; resveratrol 200 ppm; methylated resveratrol 20 ppm; methylated resveratrol 200 ppm) with 4 replicates and 10 birds per replicate. Birds were reared for 35 days, and, at the age of 35 days, eight birds of average weight from each replicate were selected for blood samples collection. There were no significant differences on feed intake and feed conversion ratio. But final body weight and weight gain in antibiotics, resveratrol and methylated resveratrol treatments were significantly higher than no-antibiotics and ${\alpha}$-tocopherol treatments (P<0.05). There were no significant differences on carcass rate and relative organ weights among treatments, however, weights of liver and bursa of februcius in antibiotics, resveratrol and methylated resveratrol treatment were lower than other treatments. Weight of pancreas was high in resveratrol and methylated treatment. On the cecal microflora (total microbes, Coliform bacteria, Salmonella spp., and lactic acid bacteria), these in resveratrol and methylated resveratrol treatments didn't show the differences compared with those in no-antibiotics, antibiotics, and ${\alpha}$-tocopherol treatments. In the serum, there were no significant differences on creatinine, blood urea nitrogen (BUN), total protein, albumin, globulin, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) among treatments, though globulin contents of reseveratrol 200 ppm and methylated resveratrol 20 ppm treatments decreased compared to those of other treatments. Immunoglobulin (IgA, IgG and IgM) were significantly decreased in antibiotics and resveratrol treatments compared to that of no-antibiotics and ${\alpha}$-tocopherol treatments (P<0.05). Superoxide dismutase (SOD) like activity tended to increase in resveratrol groups (P<0.05), however, there was no significant difference on malondiakdehyde (MDA) content among treatments. In conclusion, these results showed that resveratrol derived from mulberry can be used as alternative of antibiotics through improvement of broiler's performance and maintain of health.

Purpose : Serum insulin levels are useful indicator which of reflecting the function of insulin secretion in pancreatic ${\beta}$ cell and diagnosis of diabetes, differentiating the cause of impaired glucose tolerance. Insulin measurement kits have shown some differences in many ways such as test methods as well as quality control. The purpose of this study was to evaluate the diagnostic performance of seven manufacturing companies commercial kits. Materials and Methods : The values of insulin measured by three manufacturing companies (Biosource, Siemens, TFB) with 59 samples in August 2009 were compared with those measured by four manufacturing companies (Immunotech, Izotope, BNIBT, Cisbio) with 68 samples in December 2011. We evaluated precision, recovery rate, dilution test and correlation of serum insulin measurement using seven manufacturing company kits. Statistical program SPSS 12.0 was used for the verification of results. Results : The coefficients variation of the precision on all seven different kits were showed within 5.0%. Recovery rate of Biosource, Siemens, TFB kits on three different levels showed 94.2~103.7%, 99.0~104.6%, 99.7~107.6% respectively. Immunotech, Izotope, BNIBT, Cisbio were 93.5~99.1%, 91.4~99.1%, 99.2~131.0%, 84.8~102.3% respectively. There was strong correlation between the measurement of insulin by Biosource kit and that by two commercial kits, Siemens (R2=0.96), TFB (R2=0.99). There was good correlation between the measurement of insulin by TFB kit and that by three commercial kits, Immunotech (R2=0.97), Izotope (R2=0.96), Cisbio (R2=0.97). In the dilution test performed with more than 200 ${\mu}IU/ml$ high concentration samples, samples with diabetes correctly was measured in all seven manufacturing kits. However, as measured with insulinoma samples TFB, Siemens, Izotope, Cisbio kits were correctly measured, but Biosource and Immunotech kits were measured 47.4 ${\mu}IU/ml$, 72.3 ${\mu}IU/ml$, respectively. Conclusion : Serum Insulin radioimmunoassay kits were showed excellent precision, correlation and good recovery rate. However, some kits were not measured correctly in the high concentration insulin values. when selecting a kit should be considered many factors that cost effectiveness, compatible for automation equipment, high performance kit, the environment for each laboratory such as reaction time and reporting time.

Purpose: Gall bladder (GB) stones in children are rarely observed, and so reports of them have been quite limited in Korea. Therefore, we tried to assess the epidemiology and clinical features of children with GB stone diagnosed at Severance Hospital. Methods: A clinical study was performed on 18 patients below 15 years of age diagnosed with GB stone by abdominal ultrasonography or CT scan at Severance hospital from January 1999 to May 2005. Results: Concerning patients' profile, their sex ratio of male to female in total 18 cases was 2 : 1 with the mean age of $6{\pm}4.3years$. 15 patients (83.3%) were asymptomatic. Inducing factors were found in 14 children (77.8%) including ceftriaxone therapy in 6 cases (33.3%), infection in 4 cases (22.2%), spherocytosis in 3 cases (16.7%), Down syndrome and abdominal operation in 1 case (5.6%) respectively. Single stone was found in 13 cases (76.5%) and multiple in 4 cases (23.5%). 15 cases (88.2%) had the stones less than 5 mm in size, and 2 cases (11.8%) between 5 and 10 mm. 17 patients received conservative treatment, and one patient had cholecystectomy due to Meckel diverticulum. Conclusion: In this report, Pediatric GB stones are predominant in male children, without typical symptoms, having inducing factors, single and small. Recently the diagnosis of them has been increased because of the development of imaging study. But the reports for them were still rare in Korea. Therefore the study for them is more necessary to find it's clinical characteristics.

This study was performed to investigate improvements in diabetes mellitus by extracts of yacon in streptozotocin (STZ)-induced diabetic rats. Fifty rats were divided into a normal group and four experimental groups. STZ (45 mg/kg) was injected intraperitoneally to induce type I diabetes in the four experimental groups. Yacon extracts were administered for 5 weeks. Forty-five ICR mice were also divided into one positive control group and four experimental groups for the oral glucose tolerance test (OGTT) after fed yacon extract. The control group did not eat any yacon extracts, while Group 1 (GI) was fed 125 mg/kg of yacon extracts, Group 2 (GII) was fed 250 mg/kg of yacon extracts, and Group 3 (GIII) was fed 500 mg/kg of yacon extracts. After treatment for 5 weeks, blood glucose in GIII group showed decreased tendency at the 5 week. In OGTT by glucose, the glucose level of yacon treatment group in diabetic rats was significantly decreased compared to the glucose level of the control group, but there was no difference in OGTT by maltose. In ICR mice, the glucose level of the experimental group in OGTT by maltose was significantly decreased compared to the control group. The area of the islets of Langerhans was increased by yacon treatment in a dose-dependent manner on diabetic rats. Insulin concentration of the GIII group was also decreased compared to the control group, while the concentration of fructosamine, total cholesterol, and triglycerides in serum showed no difference. OGTT by glucose or maltose in ICR mice or diabetic rats, area of the Islets of Langerhans, and insulin concentration improved. Yacon treatment may be a useful therapeutic and preventive strategy for diabetes mellitus.

The effects of Cordyceps militaris on weight gain, flood intakes, flood efficiency ratios, serum and hepatic lipid concentrations, serum protein levels and serum enzyme activities, were studied in adult male rats. Sprague-Dawley rats, 35 weeks old, were given four different types of diets for a succeeding period of five weeks: either a normal diet(5% com oil), a high fat diet(5% com oil + 15% lard). a CF diet (high fat diet + 3% Suiting body of cordyceps militaris), or a CM diet (high fat diet + 3% mycelium of cordyceps military). The body weight gains, hepatic weights and food efficiency ratios of the rats find (high fat) diets with CF and CM were significantly decreased compared with those find the high fat diet, but were similar to those find the normal diet. The concentrations of serum and hepatic triglycerides, and hepatic total lipids and cholesterol, of rats given CF or CM diets were significantly lower than those given the high fat diet. But the concentrations of total cholesterol, HDL-cholesterol, phopholipid and total protein in the serum of rats find the high fat, CF or CM diets were significantly higher than those find the normal diet. In the serum of the rats find the CF diet, the HDL-cholesterol/total cholesterol ratio was significantly higher but the atherogenic index was significantly lower than those fed the high fat diet. The alkaline phosphatase activity in the serum of the rats find the high fat, CF, and CM diets was more significantly decreased compared to rats on the normal dirt. No differences were noted in the weights of the pancreas, kidney and heart, the serum concentrations of glucose, hemoglobin and albumin, and the activities of GOT, GPT and ${\gamma}$-GTP, among the rats on all the experimental diets. In conclusion, the rats find the Cf or CM diets maintained normal body and hepatic weights. Despite of the high intake of fats in the CF and CM diets, the concentrations of total lipids, cholesterol and triglycerides were decreased in the liver, also, the concentration of triglycerides was decreased in the serum.

Purpose: Dendropanax morifera Leveille (DML) exhibits diverse biological and pharmacological activities, including anti-oxidative effect, anti-cancer activity, hepatoprotection, immunological stimulation, and bone regeneration. As part of the identification for novel functions of DML, we investigated the therapeutic effects of DML on diabetes induced by streptozotocine (STZ) treatment. Methods: First, the four extracts including the water extract of leaf (DLW), the ethanol extract of leaf (DLE), the water extract of stem (DSW), and the ethanol extract of stem (DSE) were collected from the leaf and stem of DML using a hot water and ethanol solvent. Alterations in body weight, glucose concentration, insulin level, and pancreatic islet structure were investigated in diabetic mice after treatment with extracts of DML for 2 weeks. Results: Among four extracts, the highest level of total polyphenols and total flavonoids was detected in DLW, while the lowest level of these was measured in DSE. The radical scavenging activity was also higher in DLW than in the other three extracts at the concentration of $25-100{\mu}g/mL$, although this activity was maintained at a constant level in all groups at the concentration of $500{\mu}g/mL$. Based on the results of anti-oxidant activity, DLW and DLE were selected for examination of anti-diabetic effects in a diabetes model. Body weight was gradually decreased in all STZ treated groups compared with the No treated group. However, four STZ/DML treated groups maintained a high level of body weight during 7-14 days, while the STZ/vehicle treated group showed a gradual decrease of body weight during the same period. Also, a significant decrease or increase in the concentration of glucose and insulin in the blood of the diabetes model was detected in a subset of groups, although the highest increase was detected in the STZ/DLE-200 treated group. In addition, the histological structure of pancreatic islet was significantly recovered after treatment with DLW and DLE. Conclusion: These results suggest that DLW and DLE may contribute to attenuation of clinical symptoms of diabetes as well as prevent the destruction of pancreatic ${\beta}$-cells in STZ-induced diabetes mice.

Purpose : The differential diagnosis between Modic type I degenerative spine and infectious spondylitis sometimes is difficult, because the affected bone marrows in both disease show similar signal intensity on conventional MR imaging. We evaluate the usefulness of diffusion-wighted MR imaging for differential diagnosis between Modic type I degenerative spine and infectious spondylitis. Materials and methods : The spin-echo and diffusion-weighted MR images of eight patients with Modic type I degenerative spines and 14 patients with infectious spondylitis diagnosed by clinical findings or CT-guided biopsies we re analyzed. The diffusion-weighted imaging sequence was based on reversed fast imaging with steady-state precession (PSIF). Signal intensity changes of the vertebral bone marrow on conventional spin-echo and diffusion-weighted MR imaging were compared between degenerative spine and infectious spondylitis. Results : On T1-weighte d images, the affeted bone marrow in both disease showed hypointense signals. On T 2-weighted images, all of type I degenerative spine and 11 of infectious spondylitis showed hyperintensity, and three of infectious spondylitis showed heterogeneo us mixed signal intensity. On diffusion-weighted MR images, all of type I degenerative spine were hypointense with peripheral high signal intensity to normal vertebral body, but infectious spondylitis was hyperintense (n = 11) and hypointense (n=3). Conclusion : Diffusion-weighted MR imaging is useful to differentiate Modic type I degenerative spine from infectious spondylitis. On diffusion-weighted images, the high singal intensity of bone marrow suggests infectious spondylitis, whereas the low signal intensity of bone marrow with peripheral focal high signal intensity suggests type I degenerative spine.

The aim of this study was to investigate the hypolgycemic activity of water extract of fermented yacon (Smallanthus sonchifolius) leaves tea (Yacon LWE) in high-fat diet (HFD)/streptozotocin (STZ)-induced diabetic mice. Male ICR mice were fed with a HFD (37% calories from fat) for 4 weeks prior to intraperitoneal injection with STZ (100 mg/kg body weight). Diabetic mice were supplemented with two doses of Yacon LWE (0.16% and 0.8%, wt/wt) for 6 weeks. The supplementation of high-dose Yacon LWE significantly lowered blood glucose levels and plasma ALT and AST activities compared with the control group. High-dose Yacon LWE also improved the insulin tolerance without any changes in plasma and pancreatic insulin concentrations in HFD/STZ-induced diabetic mice. Yacon LWE supplementation increased the insulin staining of pancreatic $\beta$-cells in a dose-dependent manner. Both 0.16% and 0.8% of Yacon LWE significantly elevated plasma leptin concentration, hepatic glucokinase activity and glucokinase/glucose-6-phosphatase ratio compared with the control group. However, glycosylated hemoglobin concentration was not different among the groups. These results suggest that high-dose Yacon LWE lowers the blood glucose level partly by enhancing insulin sensitivity and hepatic glucose metabolism in type 2 diabetic mice.

This study was performed to estimate the quantity of the effects of tobacco price raise on the smoking rate, and the smoking attributable deaths in Korea. The data were collected by questionnaire survey from 538 male of male workers. The questionnaire contained items on age, sex, living place, status of education, smoking history, the intention to quit smoking when the tobacco price be raised. The questionnaire, were distributed to the offices of enterprises, hospitals, research centers, and public agencies and then collected. Data were analyzed by using the age specific smoking rate, relative risks of eight major smoking related diseases, vital statistics, and the population attributable risk of deaths of smoking males. On the other hand, the impact of the tobacco price raise on the population attributable risk of death due to smoking in Korea was estimated by applying the presumed smoking rate after the price raise. The results obtained were as follows: 1. The smoking rate of male white color workers in large cities was 59.5%. 2. The proportion of male smokers who has the intention to quit smoking when the tobacco price be raised was 61.5%. 3. The proportion of male smokers who has the intention to quit smoking if the price of tobacco be raised was proportional to the degree of increasing tobacco price. It is estimated that if the tobacco price were raised more than four times as now, the presumed smoking rate goes down as low as 26.7%. If the tobacco price be raised 20% each year, presumed smoking rate is 46.2%. 4. The number of attributable male death of smoking estimated by using 8 major smoking related diseases(lung cancer, laryngeal cancer, esophageal cancer, stomach cancer, pancreatic cancer, cerebrovascular disease, ischemic heart disease, chronic obstructive pulmonary disease) was 25,863 death each year. That is 20.1% of total age over 20 male deaths. 5. f the tobacco price were raised more than four times as now and all smokers who has intention to quit smoking quits smoking, 12,336 lives, or 47.7% of smoking related deaths could be saved. 6. IF the actual practice rate of quitting smoking among male smokers with intention to stop smoking when the price of tobacco be raised is 10%, 25%, or 50%, then the expected decrease of death numbers when the tobacco price were raised more than four times as now can be 1,112, 3,483, 5,796 respectively.
