Effects of dietary protein sources and their amino acid compositions on the liver and plasma cholesterol levels in growing Single Comb white Leghorn male chicks were studied. A diet containing isolated soy protein (21% cp) was supplemented with 0.5% DL-methionine and 0.3% L-glycine. and another diet containing casein(21% cp) was supplemented with 1.5% L-arginine HCl, 0.4% DL-methionine. and 1.0% L-glycine. Plasma cholesterol level was markedly lower in groups force-fed the diets containing either soy protein or casein supplemented with amino acids compared to those found in birds fed corresponding diets without amino acids supplementation. The cholesterol lowering effect of the casein diet. when balanced with various supplemental amino acids appeared to be due to arginine instead of methionine or glycine. It is likely that amino acid balance rather than the composition of a specific amino acid is one of the major factors determining the effect of dietary protein sources on the blood cholesterol levels in chicks.

Weanling male rats were fed a semi - synthetic diet containing either 10% corn oil, or 10% hydrogenated coconut oil (HCO) for 5 weeks. They were analyzed for plasma, liver, heart, testis, kidney and adrenal lipid compositions ; total lipids, total cholesterol, phospholipid, and triglyceride. The rats fed essential fatty acids deficient diet grew comparably with corn oil group and did not any dermal symptoms of EFAs deficiency. The most remarkable changes found in lipids of rats in experimental groups were ; (1) an increase in the concentration of plasma TG and liver TG in HCO group. (2) a decrease in the concentration of plasma PL and an increase in the concentration of testis PL of HCO group. (3) A decrease in cholesterol level of testis, kidney and adrenal of HCO group. Although this study did not show the profound EFA deficiency in weanling rats, this study showed the possibility of early nutrition affecting subsequent development in various tissues.

This research was for investigating the physiological effect caused by genetic disorder and others. Serum protein, serum LDH, and serum CPK were analyzed on Fragile X syndrome patients, carriers, unclassified mental retardees, and Down's syndrome patients by cellulose acetate plate electrophoresis. Also enzyme activity of LDH and CPK were measured. Significant differences were observed between normal group and mental retardees in compositions of serum protein, serum LDH, serum CPK, and enzyme activities. Mean percentages of albumin were 53.70$\pm$7.73% for Fragile X syndrome patients, 57.09$\pm$7.73% for carriers, 47.33$\pm$6.06% for unclassified mental retardees, 50.19$\pm$ 15.72% for Down's syndrome patients. Mean percentages of ${\gamma}$-globulin were 19.64$\pm$6.71% for Fragile X syndrome patients, 19.24$\pm$3.38% for carries, 25.66$\pm$4.74 for unclassified mental retardees, 23.41$\pm$6.08% for Down's syndrome patients. Mean percentages of LDH3 were 27.76$\pm$2.72% for Fragile X syndrome patients, 22.70$\pm$2.76% for carriers, 25.42$\pm$1.26% for unclassified mental retardees, 27.72$\pm$2.58% for Down's syndrome patients. Mean percentages of LDH4 were 2.70$\pm$2.04 for Fragile X syndrome patients, 3.79$\pm$2.74% for carriers, so both of them were significantly lower than normal(P<0.05). Mean percentages of CK-MB were 3.96$\pm$5.56% for Fragile X syndrome patients, 8.80$\pm$7.92%. Mean percentages of CK-MM were 95.81$\pm$5.50% for Fragile X syndrome patients, 91.20$\pm$7.92% for carriers. These results showed that significant abnormal compositions of blood proteins might be caused by genetic disorder. However, further analysis of many patients will be needed for clear conclusion.

Weanling male Sprague-Dawley rats were divided into 4 groups according to the level of plasma cholesterol and then fed diets containing 15%(w/w) corn oil, lard or evening primrose oil (EPO) with 0.5% (w/w) of cholesterol. Corn oil without cholesterol was used as a dietary lipid source of control diet. After 4 weeks of feeding, the fatty acid compositions of the red blood cell membrane and aorta phospholipids were analyzed together with the plasma cholesterol level. The rats fed with EPO characterized by its content of gamma-linolenic acid (GLA) showed lower cholesterol concentration in plasma than the other groups . In the corn oil groups, plasma cholesterol level was not affected by the addition of dietary cholesterol. The concentrations of dihomogamma-linolenic acid and arachidonic acid, metabolites of GLA, in the tissue were increased in the EPO group compared with the other groups.

Objectives Excess weight and obesity are a crucial public health problem worldwide and are considered as the main cause of many chronic diseases. The present study evaluated the effects of Aronia melanocarpa extract (AMEX) supplementation on body compositions in overweight or obese people. Methods This randomized, double-blind, placebo-controlled clinical trial was carried out on 66 healthy overweight or obese peoples. The eligible subjects were divided into AMEX and placebo supplement treatment for 12 weeks. Anthropometrics, body composition (dual-energy X-ray absorptiometry), and blood analysis were performed preand post intervention. Results We observed significant reductions in the body weight and body mass index in both groups; however, the decrease was higher in the AMEX group. Body fat mass and percent body fat showed a tendency to decreases after AMEX supplementation. No clinically significant changes were observed for any safety parameter. Conclusions In conclusion, the data of this trial indicate that AMEX were not effective in reducing body compositions, but as a safe supplement, it may help weight loss in overweight or obese people.

The objective of this study was to evaluate the effects of dietary Solanum nigrum L. (SNL) and Glycyrrhiza uralensis Fisch (GUF) mixture powder on performance and blood compositions of broilers. Seven-day old Ross broiler male chickens were randomly given into one of the 5 dietary treatments for 5 weeks: 1) no SNL-GUF and antibiotics (control); 2) 5 ppm avilamycin (T1); 3) 0.5% SNL and GUF (T2); 4) 1.0% SNL and GUF (T3); and 5) 2.0% SNL and GUF (T4). Each dietary group (n = 10) had three replicates. Body weight gain, feed intake and feed conversion ratio of broiler chickens were not significantly different among treatments. Carcass weight was highest at both 4 (P<0.05) and 6 weeks (P>0.05) in the treatment with 1.0% SNL and GUF. Liver, but not Spleen, weights at both 4 and 6 weeks were significantly higher in the treatments with 0.5% SNL and GUF treatment (P<0.05). The contents of protein, albumin, bilirubin, glutamic-oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), glucose, triglyceride (TG) and cholesterol in blood serum at the 4weeks and 6 weeks were not significantly influenced. These results suggest that addition of SNL and GUF could be use a substitutes for antibiotics since they did not influence to the productivity and the blood composition of the broilers.

The principal objective of this study was to investigate the effects of silkworm sericin extract supplementation on the improvement of lipid compositions, blood glucose levels and enzyme activities in the serum of dyslipidemic rats. The rats were fed the experimental diet for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL-cholesterol, triglyceride (TG), phospholipid (PL), free cholesterol, cholesteryl ester ratio and blood glucose in serum were higher in the dyslipidemic group (group HCW) and cholesterol-plus-silkworm sericin extract intake group (group HCS) than those in the control group (group BW, basal diet-plus-water). However, the concentrations of total cholesterol, atherosclerotic index, LDL-cholesterol, TG, PL, free cholesterol, cholesteryl ester ratio and blood glucose level in serum were lower in group HCS than those in group HCW. On the other hand, the HDL-cholesterol level and the ratio of HDL-cholesterol to total cholesterol in group HCS were higher than in group HCW. The activities of alkaline phosphatase (ALP) and aminotransferase (AST & ALT) in serum were lower in group HCS than in the dyslipidemic group HCW. From the above results, it was suggested that silkworm sericin extract intake was effective in the prevention and improvement of lipid components, blood glucose level and enzyme activities in the sera of dyslipidemic rats.

This study was performed to investigate the effects of the chitosan oligosaccharide administration on the improvement of the lipid compositions, blood glucose and enzyme activities in the serum of hypercholesterolemic rats fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglyceride (TG), phospholipid (PL) and blood glucose in serum were higher in the hypercholesterolemic group (group CW) and cholesterol+chitosan oligosaccharide administration group (group CCW) than those in the control group (group BW, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, TG, PL and blood glucose in serum were lower in the group CCW than those in the CW, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the group CCW were higher than in the group CW. The activities of alkaline phosphatase (ALP) and aminotransferase (AST, ALT) in serum were lower in the group CCW than in the hypercholesterolemic group CW. From the above results, it was suggested that chitosan oligosaccharide administration was effective in the prevention and improvement of the lipid level, blood glucose and enzyme activities in serum of hypercholesterolemic rats.

The prevalence of atopic dermatitis (AD) continues to rise in industrialized countries related to Western lifestyle, including dietary habits, especially imbalance of intake of dietary fatty acids. The purpose of this study was to evaluate the dietary fatty acids and the assess the blood fatty acid composition and immune parameters in AD patients. AD (n = 50) patients and gender ${\cdot}$ age matched healthy controls (HC) were studied in case-control clinical trail. Current fatty acids intake status was determined by 3-day food record method. Blood sample were collected from 30 subjects in each group and blood fatty acid composition and immune parameters were analysed. AD patients consumed less PUFA and their n-6/n-3 PUFA ratio was higher than that of HC. Both the ratios of PUFA and MUFA were positively correlated with SCORAD in AD patients (p < 0.05). In the AD patients, there were abnormalities in the fatty acid composition of the RBC and WBC, SFA being significantly high and most n-3 PUFA being significantly low. Moreover, both the ratios of EPA and DHA in WBC were negatively correlated with dietary n-6/n-3 PUFA ratio in AD patients (p < 0.05). Serum total IgE and IL-4 levels of AD patients increased significantly compared with the levels of HC (p < 0.01). Ratios of monocyte and eosinophil in WBC of AD patients increased significantly compared with the levels of HC including total WBC count (p < 0.01), and ratios of Iymphocyte and basophil in WBC of AD patients decreased significantly compared with the levels of HC (p < 0.05). Moreover, the ratios of eosinophil in WBC were positively correlated with dietary P/M ratio (p < 0.05), and the ratios of monocyte in WBC were positively correlated with n-6/n-3 PUFA ratio (p < 0.05) in AD patients. This results indicated that AD patients had significantly high intake of dietary n-6/n-3 PUFA compared with HC. Imbalance of intake of dietary fatty acids affected fatty acid compositions in the RBC and WBC, and these lead to immune imbalance and grow worse of AD.

This study was designed to investigate the relationships of depressed mood with obesity, blood and urinary compositions, and dietary habits in Koreans at the age of 40, a critical transition to the middle adulthood stage. A total of 27,684 people who have taken the Life Transition Period Health Examination at the Korea Association of Health Promotion in 2011 were divided into two groups; the depressed mood group (DG) and the non-depressed group (NG) according to results of the primary questionnaire for mental health. The results were analyzed using the health examination criteria of the National Health Insurance Corporation. Women and medicaid recipients showed higher incidence of depressed mood than men and health insurance subscribers. People with underweight in BMI or abdominal obesity showed correlation with depressed mood, while there was no significant relationship with metabolic syndrome. Regarding blood and urinary compositions, DG was related to a higher level of hemoglobin and lower levels of HDL-cholesterol and triglyceride, although the relationships diminished after adjustment for other confounder effects. According to dietary habits, more people in DG were categorized as a group for "Needs Much Improvement", and the odds ratio of the depressed mood showed a significant increase. Significant difference regarding the frequency of food items such as milk products, animal proteins, Kimchi, and fruits was observed between DG and NG. In addition, a higher portion of subjects in DG did not consume regular meals and various kinds of food. In conclusion, the depressed mood of 40 year-old adults was significantly related to underweight, higher waist measurement, and undesirable dietary habits. Results of our study can be applicable as a basic resource for development of effective nutrition counseling and education programs for improvement of mental health promotion during the critical transition to the middle adulthood stage.
