Purpose: We conducted this study to study the clinical correlation between the characteristics of gastric cancer and serum selenium and zinc levels. Materials and Methods: The following data were measured in the baseline serum selenium and zinc levels of 74 patients with curative gastrectomy subsequent to confirmed gastric cancer, from March 2005 to August 2012. Results: Among the 74 gastric cancer patients, 53 patients were male. Mean serum selenium and zinc levels were $118.7{\pm}33.1$ ug/L and $72.2{\pm}24.3$ ug/dl, respectively. Seven patients (9.5%) showed lower selenium level, and 33 patients (44.6%) showed lower zinc level. Serum Selenium level was $99.1{\pm}31.8$ ug/L in cardia cancer group (10 cases) and $121.8{\pm}32.4$ ug/L in non-cardia cancer group (64 cases)(P=0.044). According to tumor gross type, zinc level was $78.7{\pm}29.6$ ug/dl in early gastric cancer (33) and $66.9{\pm}17.8$ ug/dl in advanced gastric cancer (41) (P=0.064). Conclusions: The serum selenium level was highly correlated with the location of gastric cancer. The serum zinc level was lower in advanced gastric cancer.
Purpose: The aim of this study was to analyze any association between the metabolic syndrome (MetS) and risk of prostate cancer (PCa) and cancer grade among men undergoing radical prostatectomy for PCa. Materials and Methods: 50 patients with MetS and 50 patients without MetS who undervent radical prostatectomy (RP) were included in the study. Age at biopsy, height, weight, digital rectal examination (DRE), pre-biopsy PSA levels, prostate volume, histopathologic diagnosis after surgery and gleason scores were collected data from all patients. Histologic material obtained at biopsy was given a Gleason score; tumours with a Gleason score ${\geq}7$ were considered high grade and <7 were considered low grade. Results: The mean age at the time of biopsy was $63.7{\pm}5.94$ in patients with MetS and $61.6{\pm}6.14$ in patients without MetS. Men with MetS had significantly lower PSA levels (p=0.01) ($7.21{\pm}2.74$ and $8.81{\pm}2.72$, respectively). Also, the men with MetS had higher RP tumor grade (p=0.04). Conclusions: Men with MetS undergoing RP have lower PSA levels and have significantly higher grade PCa. We must be careful for screening PCa in patients with MetS. Although the patients had lower PSA levels, they may have high grade disease.
Resistin, adiponectin, and leptin are hormones secreted by adipose tissue and are known to play an important role in adipose tissue metabolism. The purpose of this study was to evaluate the levels of adipocyte-derived hormones (resistin, adiponectin, leptin) in obese children aged 10-12 years. The subjects were 102 obese children with obesity index (OI) over $120\%$ and 51 control children with obesity index less than $120\%$ were included for comparison. Anthropometric variables and serological parameters were assessed. Height, weight, OI, body mass index (BMI) were significantly higher in obese group than in control. Obese children showed significantly higher serum concentrations of triglyceride (TG), total cholesterol (TC), and LDL-cho1esterol and significantly lower HDL-cholesterol compared with control children, even though the values were within normal ranges for both groups. Concentrations of resistin and leptin were significantly higher in obese group than in control. Adiponectin and insulin levels were tended to lower in obese group even though the differences were not statistically significant. Resistin had significant positive correlation with OI and TG, and 1eptin with weight, OI, BMI, TG and TC. On the other hand, adiponectin showed significant negative correlations with height, OI and BMI. These finding showed that obese children had higher serum levels of resistin and leptin and lower adiponectin, and also these hormones had correlations with related factors of obesity, suggesting adipocyte-derived hormones has a role in child obesity.
This study determined the effects of dietary restriction on growth and the expression of lipid metabolism and growth hormone signaling genes in the longissimus dorsi muscle (LM) of Korean cattle. Thirty-one Korean cattle steers (average age 10.5 months) were allocated to normal (N; n = 16) or dietary restriction (DR; n = 15) groups. The feeding trial consisted of two stages: for the 8-month growing period, the DR group was fed 80% of the food intake of the normal diet, and for the 6-month growth-finishing period, the DR group was fed a DR total mixed ration with 78.4% of the crude protein and 64% of the net energy for gain of the normal diet. The LM was biopsied 5 months (period 1 [P1] at 15.5 months of age) and 14 months (period 2 [P2] at 24.5 months of age) after the start of feeding. The mRNA levels were determined using real-time polymerase chain reaction. Body weight, daily feed intake, average daily gain, and feed efficiency were lower in the DR group compared with the normal group at both P1 and P2. At P1, the lipogenic fatty acid synthase (FASN) mRNA levels were lower (p<0.05) in the DR group compared with the normal group. The DR group tended (p = 0.06) to have higher of levels of growth hormone receptor (GHR) mRNA than the normal group. At P2, the DR group tended to have lower (p = 0.06) androgen receptor (AR) mRNA levels than the normal group. In conclusion, our results demonstrate that dietary restriction partially decreases the transcription of lipogenic FASN and growth hormone signaling AR genes, but increases transcription of the GHR gene. These changes in gene transcription might affect body fat accumulation and the growth of the animals.
Background: Social support is an important factor in psycho-social well-being of cancer survivors. There is little information about level of social support and its predictors among cancer survivors in Iran or other Middle Eastern countries. The aims of present study were to determine the social support and its prediction factors among Iranian cancer survivors. Materials and Methods: In this descriptive-correlational study 187 cancer patients in one educational center and one private oncology office in northwest of Iran participated using a convenient sampling method. The data collection tool consisted of a researcher-prepared checklist and the Multidimensional Scale of Perceived Social Support Assessment (MSPSS). Data analysis was performed using SPSS statistical software with descriptive statistics and multiple linear regression analysis. Results: The total score of MSPSS was 68 from a possible score between 7 and 84. Participants believed that they received a high level of support from their family members and significant others. Multiple linear regression analysis showed that single and depressed cancer survivors and participants with lower levels of physical activity believed that they received lower levels of social support. Conclusions: Iranian cancer survivors receive high levels of social support and family members are the most important source of this support. In planning any supportive care program for Iranian cancer survivors this strength should be considered. Especially, single and depressed and patients with lower levels of physical activity need more attention.
This study was designed to examine the effects of Salicornia herbacea L. (glasswort: GW) on the plasma blood glucose and lipid metabolites in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats weighing 200-220g by an injection of streptozotocin (STZ) dissolved in a citrate buffer into the tail vein at a dose of 45 mg/kg of body weight. Sprague-Dawley rats were fed an AIN-93 recommended diet and the experimental groups were fed a modified diet containing 10% and 20% of glasswort powder for 4 weeks. The experimental groups were divided into 6 groups which consisted of normal (N)-control group, N-GW 10% and N-GW 20% treated groups, STZ-control, STZ-GW 10% and STZ-GW 20% treated groups. The rats' body weights, aminotransferase activities and hematocrit (Hct) values were measured, along with plasma levels of glucose, protein, cholesterol, HDL-cholesterol, triglyceride (TG) and free fatty acids (FFA). The non-diabetic rats gained weight, while the diabetic rats lost weight. There were significant differences between the control group and the diabetic groups in the weight of the kidney, liver and pancreas. Asparate aminotransferase activity was lower in the non-diabetic control group compared to diabetic experimental groups, even though the difference was not significant. The plasma protein of N-GW 20% group was lower among all experimental groups but it was not significantly different. The blood glucose levels of the STZ-GW 10% group and STZ-GW 20% group were significantly lower than for the diabetic-control group. There were no significant difference of cholesterol levels among diabetic groups. The normal rats of 20% glasswort group in FFA and TG levels showed significant changes among all groups. These results exhibited dose related effect of glasswort and it may contain antihypoglycemic compounds.
In this study, we analyzed the biochemical factors in lotus (Nelumbo nucifera) leaf, stem, and yeonjabang and their effects on serum factor levels in mice fed a high-fat (HF) diet. The loutus leaf showed $9.47{\pm}0.30%$ moisture content, $8.25{\pm}0.39%$ ash, $21.45{\pm}1.25%$ crude protein, and $2.21{\pm}0.13%$ crude fat content; the lotus stem showed $11.84{\pm}0.43%$ moisture, $10.21{\pm}0.64%$ ash, $17.55{\pm}0.92%$ crude protein, and $4.16{\pm}0.23%$ crude fat content; and the lotus yeonjabang showed $11.86{\pm}0.50%$ moisture, $6.81{\pm}0.51%$ ash, $18.71{\pm}1.02%$ crude protein, and $3.95{\pm}0.15%$ crude fat. Blood triglyceride levels were higher in the HF group ($146.43{\pm}38.81mg/dL$), and lower in the HF+yeonjabang groups ($98.00{\pm}17.18mg/dL$). In particular, blood triglyceride levels were significantly lower in the groups that had 10% dry yeonjabang powder added to the high-fat diet. The inclusion of excessive high-fat diet increased concentrations of serum insulin and leptin. Serum leptin concentrations were highest in the HF group mice ($3.00{\pm}1.35ng/dL$), whereas they were significantly lower in the HF+yeonjabang groups by $1.34{\pm}0.52ng/dL$ (p<0.05). Thus, addition of dry yeonjabang powder to the high-fat diet was more effective in regulating the levels of serum triglycerides and leptin in mice. Additional studies would help in the development of yeonjabang as a functional food.

A concern of safety issue for traditional herbal medicine is the possibility of some herbs containing heavy metals responsible for several cases of metal poisoning. In our previous study, the physiological levels of heavy metals, such as Cd, Cu, Hg and Pb, were examined to evaluate a potential risk in patients taking herbal medicine. In this study, the levels of 12 heavy metals, including non-metallic element, Se, were analyzed in hair and compared to the results from the previous study. In the previous study, the levels of Cd, Cu, Hg and Pb in hair showed a significantly lower odds ratio than 1. In this study, however, all metals did not show any significant odds ratio higher or lower than 1 even if 5 of 12 metals showed lower odds ratio than 1. In addition, the levels of metal concentrations, especially for Cu, Fe, Pb and Zn, exceeding the WHO reference values were observed in hair. However, any evidence for metal accumulation in hair caused by taking herbal medicines for long duration was not observed in analysis of multiple regression and odds ratio from case-control study. This result would show another possibility for a role of herbs as a non-enzymatic chelator inhibiting the gastrointestinal absorption of heavy metals.
To study effects of methanol extract of prosomillet on lopid metabolism , five groups of male Sprang-Dawley rats weighing 116$\pm$9 g were fed test diets for four weeks. The five diets consisted of one low fat(5% w/w) diet containing starch as carbohydrate source(normal) and four high fat diets(15% w/w) containing 40.5%(w/w)sucrose(control) and additional 80% nethanol extractof prosomillet at the levels of 0.3% and 1%(w/w) or prosomillet powder at the level of 20%(w/w). Serum level of total cholesterol was a little higher but that of triglyceride was 41% lower in 20% (w/w) prosomillet powder group than in the control group. The cholesterol levels of two Liver cholesterol levels were lower and phospolipid levels higher in all three prosomillet powder group . Fecal excretionof bile acid was most increased in the prosomillet powder group among all five test groups. Acitivity of liver microsomal 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase was significantly lower in 0.3% methanol extract fed group than the control and also appeared to be reduced in 1% extract fed one, wherease those of 20 cholesterol 7$\alpha$-hydroxylase were not different among the five groups. Activities of liver cytosilic glucose-6-phosphate dehydrogenase(G6PDH) and malic enzyme were decreased in 0.3% prosomillet methanol extract and 20% powder groups. The results indicate that in addition to fiber, certain active components in prosomillet have potential to exert hypolipidemic effects via regulating hepatic cholesterogenesis and lipogenesis.
Objectives: The aim of this study was to determine environmental chemical exposure related to residential and personal lifestyle characteristics in the adult Korean population. The observations of this study can provide information useful for developing reduction approaches for exposure to chemicals among the general adult population. Methods: The second stage of the Korean National Environmental Health Survey (KoNHES) was conducted from 2012 to 2014, with 6,478 persons participating. Using the results of the survey, the relationship between exposure levels of heavy metals and organic chemicals and exposure factors, e.g. residential and personal lifestyle characteristics, were analyzed. Results: The exposure levels of VOCs and PAHs were significantly lower in participants living at a distance of more than 100 m from roads versus living closer to roads. Home ventilation lowered VOC and PAH exposure but did not lower chemical exposure from household products. Use of public transportation showed lower exposure to heavy metals, VOCs, and PAHs. Current smoker was significantly higher for levels of heavy metals, VOCs, and PAHs, and the exposure trend was similar for current drinkers. Physical activity was related with higher exposure to phthalates and environmental phenols. Conclusion: Our observations based on a nationally representative population for Korea show that exposure to chemicals varies by residential and personal lifestyle, and this should be considered for developing appropriate mitigation measures and policies. Given the health concerns surrounding environmental chemicals, it is necessary to develop comprehensive measures to reduce chemical exposure.
