Depression is a major health problem that can lead to mortality. This study was conducted to assess the risk factors associated with depression in a group aged over 65 years by analyzing nationally representative Korean survey data. A total of 1,209 subjects were analyzed among the participants of the 2014 Korean National Health and Nutrition Examination Survey. Statistical methods for a complex sample were applied by using SPSS program(windows ver. 24.0). Depression assessments were carried out by using the 9-item depression module of the Patient Health Questionnaire-9 (PHQ-9). Depression ($PHQ-9{\geq}5$) was more frequently found in females (33.2%) compared to males (16.1%). However, there was no evidence suggesting that characteristics such as residence area, income level and age, except for educational level, were related with depression. The results of the logistic regression analysis showed that i) health habits such as smoking (OR: 2.26) and lack of aerobic physical activity (OR: 1.62), ii) mental health status such as bad self-rating of health status (OR: 4.30), more stress (OR: 8.31), and bad health-related quality of life (by EQ_5D, OR: 3.41), iii) chronic diseases such as obesity (OR: 0.66), hypercholesterolemia (OR: 1.57), anemia (OR: 1.91), and iv) low intake of energy (OR: 1.84) and calcium (OR: 1.71) were significantly associated with depression. This study suggests that certain characteristics of health habits, mental health status, chronic diseases and nutrient intake may be associated with depression. Prospective research on long-term control is needed to establish causal connections among those factors with depression.

Obesity is a primary factor provoking various chronic disorders, including cardiovascular disease, diabetes, and cancer, and causes the death of 2.8 million individuals each year. Diet, physical activity, medications, and surgery are the main therapies for overweightness and obesity. During weight loss therapy, a decrease in energy stores activates appetite signaling pathways under the regulation of neuropeptides, including anorexigenic [corticotropin-releasing hormone, proopiomelanocortin (POMC), cholecystokinin (CCK), and cocaine- and amphetamine-regulated transcript] and orexigenic [agoutirelated protein (AgRP), neuropeptide Y (NPY), and melanin-concentrating hormone] neuropeptides, which increase food intake and lead to failure in attaining weight loss goals. Ginseng and ginsenosides reverse these signaling pathways by suppressing orexigenic neuropeptides (NPY and AgRP) and provoking anorexigenic neuropeptides (CCK and POMC), which prevent the increase in food intake. Moreover, the results of network pharmacology analysis have revealed that constituents of ginseng radix, including campesterol, beta-elemene, ginsenoside Rb1, biotin, and pantothenic acid, are highly correlated with neuropeptide genes that regulate energy balance and food intake, including ADIPOQ, NAMPT, UBL5, NUCB2, LEP, CCK, GAST, IGF1, RLN1, PENK, PDYN, and POMC. Based on previous studies and network pharmacology analysis data, ginseng and its compounds may be a potent source for obesity treatment by regulating neuropeptides associated with appetite.

To study the effects of the age and the dietary protein content on Ca metabolism male rats of 1 month 6 month 12 month of age were fed experimental diets containing 5%, 15% or 50% casein for 4 weeks. Food and ca intake were higher in old rats and in high protein groups. The weight ash and Ca contents of femur and tibia were higher in old rats. The higher dietary protein level resulted in higher skeletal weigh ash and Ca contents. But high protein diet(50% casein) lead to reduced bone mineral density(ash/dry bone weight) and Ca density(Ca/dry bone weight) in 1 month old rats. Low protein diet(5% casein) on the other hand reduced the bone growth even though the bone density was higher in this group. The ill effect of low protein diet was not evident in 12 month old rats. Glomerular filteration rate(GFR) and urinary Ca excretionincreased with age and with dietary protein level especially in 12 month old rats. Serum immunoreactive parathyroid hormone(iPTH) level tended to be higher in aged rats but was not affected by dietary protein level except 1 month old rats where 50% protein group showed significantly higher value. This study showed that the dietary protein level seemed to have different effect on Ca metabo-lism in rats of different age., The low bone density in the high protein group of growing rats may be due to the higher iPTH level and increased urinary Ca. The dietary protein level however had no effects on the bone composition in aged rats even though the higher urinary Ca excretion. In conclusion this study suggests that high protein intake from young may lead to less peak bone mass and to increase the bone loss in later years, which would increase the risk for osteporosis.

Malnutrition is a common problem in cancer patients. In addition anticancer drugs used in chemotherapy as a major therapeutic mode are famous as the side effect like nausea, vomiting, which lead the patients to malnourished state. This study was to determine the relationship of anorexia, nausea, vomiting and oral intake and identify the influence these side effects on the nutritional status in patients receiving chemotherapy. To assess the nutritional status, anthropometry such as weight, height, body mass index(BMI), body fat proportion, and triceps skinfold thickness, and biochemistry test such as hemoglobin and lymphocyte were measured at the pre- and post- chemotherapy and the readmission time, all three times. During chemotherapy, anorexia, nausea, and vomiting using a VAS or 5-point scale and 24 hour oral intake using a food record were measured daily. Forty-nine patients knowing their diagnosis and receiving chemotherapy were recruited from an oncological ward in a general hospital for 5 months and they were reduced 31 at readmission time for a next chemotherapy. The results were as follows. Most subjects (93.6%) were in the 4th stage of cancer and 57.1% of subjects were in the first or the second chemotherapy. In most subjects(82.6%), their weight was decreased 10.7% than as usual. The degree of anorexia, nausea, and vomiting was significantly higher and the amount of oral intake was significantly less during the chemotherapy than at the pre-chemotherapy. Weight, BMI, triceps skinfold were reduced more at the post- chemotherapy than the pre-chemotherapy and were recovered the nearly same but less level at the readmission time. Body fat proportion was increased at the post chemotherapy and then decreased at the readmission phase. Hemoglobin and the number of lymphocyte were below normal at the pre-chemotherapy and more reduced at the readmission time. Anorexia, nausea, and vomiting were related positively and oral intake was negatively related with nausea and vomiting. The nutritional status at the post- chemotherapy and the readmission time was explained 20% over by the side effect like anorexia, nausea, vomiting and oral intake during the chemotherapy. The significant nutrition predictors at the post- chemotherapy were vomiting and the significant predictors at the readmission time were anorexia, vomiting, and oral intake. These results indicated the patients receiving chemotherapy were continued to deteriorate the nutritional status. Therefore nurse should have knowledge how much the nutritional status can be affected and assess the nutritional status periodically and try to find out the intervention for side effects from the series of chemotherapies.

During the 1970s, concern arose that cured meats contained high levels of residual nitrite and preformed nitrosamines. Therefore, the search for alternatives and alternative approaches to the use of nitrite have been still continued, however no complete alternative for nitrite has yet been identified. Recently, it was publicized in Korea that nitrite-containing meat products would be detrimental to health, about which consumers have been seriously concerned. Therefore, this study was carried out to inform the consumer of the safety status of nitrite and thereby to lead proper consumption of meat products. For assessing the safety of nitrite, data regarding the regulation for use, metabolism in human body, and dietary intake amounts of nitrite were collected and analyzed. The mean intake level of nitrite for Korean per capita was recently reported to be not more than 1% of ADI set by JECFA. On the contrary, a calculation indicated that the daily nitrite intake per capita from saliva by ingestion of vegetables in Korea would be about 300-fold higher than that from cured meats. In consideration of the low consumption amount of meat products per capita of Korean, that is, at least one fifth, compared to European and American, there is no particular reason to concern about the impairment of health by nitrite intake from meat products for Korean. However, any effort for the reduction of residual nitrite content in cured meats should be given with an idea to minimize the intake of nitrite even from the minor source.

This study was performed to investigate nutritional effect of various dietary fibers on lead absorption, and protein and lipid metabolisms in growing rats. Sixty male rats of Sprague-Dawley strain weighing 140$\pm$1.1g were blocked into 10 groups according to body weight and fed 10 kinds of diet different with fiber sources [non-fiber, cellulose, pectin, guar gum or carboxymethylcellulose(CMC)] and lead levels (0 or 1%) for 4 weeks. Results were summerized as follows : 1) Food intake, weight gain, FER and PER were remarkably decreased in lead(Pb)-added groups. Weight gain, FER and PER in Pb-added pectin group were significantly lower than those in Pb-added non-fiber group. 2) Liver and kidney weights, femur weight and length, hematocrit and hemoglobin content were decreased in Pb-added groups. Especially femur and liver weights in pectin groups were the lowest among groups. 3) Total protein content in serum was significantly decreased in Pb-added groups but was not different with dietary fiber sources. Total lipid content in serum was not different with dietary Pb levels and fiber sources, but cholesterol content in serum of guar gum group was significantly decreased by Pb addition. 4) Nitrogen, lipid and cholesteol contents in liver were significantly decreased in Pb-added groups, and lipid content in liver of pectin and CMC groups was lower than other groups. 5) Daily urinary and fecal excretions of nitrogen, kipid and cholesterol were decreased in Pb-added groups, and fecal nitrogen was significantly increased in Pb-added groups, and fecal nitrogen of cellulose and guar gum groups was significantly higher than other groups. Fecal excretions of lipid and cholesterol were increased by dietary fibers, and especially fecal lipid was remarkably increased in pectin and guar hum group. 6) Pb contents in liver and femur were decreased by dietary fibers. Especially Pb contents in liver, kidney and femur were significantly decreased in guar gum group. 7) Daily urinary and fecal excretions of Pb were significantly increased in cellulose and guar gum groups, and fecla excretion of Pb in guar gum group was twice of non-fiber group. Pb absorption ratio was significantly decreased in guar gum group. In conclusion, dietary fibers have effect on protein and lipid metabolisms, and decreased intestinal absorption of Pb by increasing fecal excretion. But the degree of effect was different with dietary fiber sources.

This study was performed to investigate nutritional effect of various dietary fibers on lead absorption and metabolism of protein and lipid in growing rats. Forty eight male rats of Sprague-Dawley strain weighing 75.7$\pm$0.7g were blocked into six groups according to body weight and fed six kinds of diet different with fiber source(non-fiber, cellulose, pectin) and lead level(0%, 1% ) for 4 weeks. Results are summerized as follows: 1) Food intake, weight gain, FER and PER were remarkably decreased in lead(Pb) added groups, and FER and PER in Pb-added pectin group were significantly lower than those in Pb-added non-fiber group. 2) Weight of liver, kidney and epididymal fat pad, bone weight and length, hematocrit, and hemoglobin content were decreased in Pb-added groups. 3) Total protein content in serum was tended to be decreased in Pb-added groups, but total lipid and cholesterol contents in serum were not different with dietary Pb level and fiber source. 4) Nitrogen, lipid and cholesterol content in liver were tended to be deceased in Pb-added groups, and especially those of the Pb-added pectin group were the lowest among groups. 5) Daily urinary and fecal excretions of nitrogen, lipid and cholesterol were decreased in Pb-added groups. Especially fecal excretions of nitrogen, lipid and cholesterol in Pb-free groups were significantly increased by dietary cellulose and pectin. 6) Pb content in blood was significantly increased in Pb-added pectin group. There was no significant decrease in Pb contents of liver, kidney and tibia, and increase in excretion of Pb by feeding dietary fibers. In conculsion, dietary fibers had no effect on the absorption of Pb, and dietary pectin seemed to increase Pb poisoning by decreasing bioavailibility of protein, lipid and other nutrients in the diet.

취약한 구강 건강은 손상된 저작의 기능을 유발할 수 있다. 음식의 선택에서 저작의 기능이 중요한 역할을 하는지는 아직 까지도 논쟁의 여지가 있을지라도, 손상된 저작의 기능은 부적절한 음식의 선택을 하게끔하며, 따라서 영양의 섭취를 변화시킨다. 만약 이러한 가설이 맞다면, 저작 기능의 결핍은 일반적 건강에 해로운 것일 것이다. 취약한 구강의 건강과 특정한 위장의 질환 사이의 관계는 비록 과학적으로 확립되지는 않았을지라도 제안되어 왔다. 공공 건강의 정책은 자연치아를 보존함으로써 적절한 영양의 섭취를 가능케 하는 것을 강조하여야 하며, 치과의사들은 의치의 사용과 관련된 영양의 위험을 의식하여야 할 것이다.

Marked augmentation of urinary aldosterone excretion following furosemide administration was observed in previous experiment. In this study, author measured the changes of aldosterone secretion after furosemide administration in normotensive young volunteers with high sodium intake. After intravenous injection of $1.2-^3H-aldosterone$, urine samples were collected in course of time until 24 hours after the injection. Furosemide administration was done at 30 minutes prior to aldosterone injection. Specific activities of $^3H-aldosterone$ during and after diuresis were measured and aldosterone secretion rates were calculated dividing the doses by specific activities. Results were as followed 1. Furosemide resulted in a marked increase in urinary aldosterone excretion. 2. Furosemide lead to an increase in both sodium and potassium excretion. 3. Aldosterone secretion rate was also increased during furosemide diuresis, but the rate was smaller than that of urinary excretion. 4. Continuous modest increase in aldosterone secretion rate was shown after diuresis and total excess amount of aldosterone secretion for 24 hrs was equivalent to the amount of aldosterone excretion produced by diruesis. 5. Abrupt marked loss of circulating aldosterone produced by diuresis was supplemented by long lasting increase in secretion for over twenty four hours.
