This study was conducted to estimate the incidence and the degree of cigarette smoking and drinking among working men, and then to investigate the effects on blood pressure, various hematological indices and blood chemistry. The sample consisted of 2,287 male workers who had undertaken a general health check-up during the two-year period from January, 2000 to December, 2001. Such factors as blood pressure, blood glucose, lipid profiles, and liver function tests were determined and then analyzed with respect to the subjects smoking and/or drinking status. The major findings from this study are: 1. The drinking and smoking status have shown that 52.7% of participants were in the habit of both drinking and smoking while 11.6% were not associated with either. On the other hand 25.4% were involved only in drinking and 10.2% only in smoking. In the group smoking over 21 cigarettes per day over 30, the age group occupied the largest proportion at 20.1%. 2. Regarding the relationship between smoking and/or drinking status, and blood pressure, hematology and blood chemistry, the smoking and/or drinking group had significantly higher levels of blood pressure, both systolic and diastolic, Hb & Hct, TG, LDL-C, SGOT, and ${\gamma}$-GTP, than the non-smoking and/or non-drinking group. But HDL-C was significantly lower in the smoking group and significantly higher in the drinking group than the non-smoking/non-drinking group. 3. Regarding amount smoked, a larger number of cigarettes per day was significantly associated with the higher levels of blood pressure, systolic and diatolic, TG, TC, LDL-C, Hb, Hct, and ${\gamma}$-GTP. As for the amount druck, an increasing amount of alcohol intake was associated with rising levels of blood pressure, systolic and diatolic, TG, TC, LDL-C, HDL-C, Hb, SGOT, and ${\gamma}$-GTP. 4. Regarding the correlation among all the variables stated above, the smoking and drinking amount was shown to be in the positive correlation with blood pressure, both systolic and diastolic, TG, TC, Hb, and ${\gamma}$-GTP. On the contrary, LDL-C and HDL-C was in a positive correlation only with the amount drunk amount, and Hct only with the amount smoked. 5. As with systolic and diastolic blood pressure, the odds ratio of the smoking group was 2.35 and 2.58 compared to the non-smoking/drinking group. whereas it was 1.47 and 1.75 in the smoking/drinking group. Concerning serum lipids, the smoking/drinking group had 1.97 times the levels of TG in the non-smoking/non-drinking group, though the smoking group had 1.55 times the levels of HDL-C in the non-smoking/non-drinking group. As with liver function test results, the drinking group had 2.50 times and the smoking/drinking group had 4.41 times the levels of ${\gamma}$-GTP in the non-smoking/drinking group. respectively. The above results revealed that smoking and alcohol intake were effected the results of blood pressure and laboratory tests. Specifically, not only the smoking/drinking group but also those only smoking or only drinking were not as desirable as the non-smoking and non-drinking group to the results of blood pressure and laboratory tests.

The purpose of this study was to investigate the health status of preschool children using the questionnaires about dietary behaviors and anthropometric indices. And also nutritional status was investigated using questionnaires for 24-hr recall method. The study was conducted in 145 children aged 3 to 6 years and questionnaires for dietary behaviors and dietary intakes were performed by mothers of children in Ulsan. Just nine percent of children were graded as good in terms of having healthy eating habits, this means that the nutrition education for the dietary behaviors should be more focused on preschool children. With regard to the frequency of food intake, children consumed green & yellow vegetables less frequently, meanwhile consumed high protein source food (meat, egg and bean) and milk and its product more frequently. Children almost never consumed fried foods as often as 1-2 times a weak. In assessment of the health status, children have the highest prevalence of colds and allergy, but lower prevalence of clinical symptoms due to the nutritional deficiency. The mean height was $103.6\;{\pm}\;6.4\;cm$ and significantly different among age (p < 0.05), but was not significantly different between sex. The mean weight was $17.8\;{\pm}\;3.0\;kg$ and significantly different in 5, 6years old among age. By the WLI criteria, 11.1% of children were underweight and 17.4% of children were overweight or obese. By the Rohrer index criteria, any children were not underweight and 86.8% of children were overweight or obese. By the Kaup index criteria, 2.8% of children were underweight and 29.2% of children were overweight or obese. And Obesity Index criteria, 2.1% of children were underweight and 20.8% of children were overweight or obese. The results of obesity rate by all criteria except Rohrer index indicated similar level, were significantly high in age 3 with all criteria, and decreased with age increased. The energy intake of children was lower than EER (Estimated Energy Requirements) of Dietary Reference Intakes for Koreans (KDRIs) by as much as 85.7%. Acceptable Macronutrient Distribution Ranges (AMDR) was 62.6:21.5:15.7 as carbohydrate:protein:lipid, so children consumed protein more, but consumed lipid less compared with those of KDRIs. Vitamin A intake was 133% of recommended intakes (RI) and calcium intake which was identified as the nutrient most likely to be lacking in diets was 98.9% of RI. The intakes of all minerals and vitamins except folate were higher than KDRIs. 33.3% of children were distributed in insufficiency of energy intake, 42.7% of children were distributed in insufficiency of lipid intake. These results indicate that the need of developing of nutrition education program and further concern of a public health center, university and children care center about dietary life for preschool children.

The current study was performed to develop natural bio-active substances as additives for the production of high quality broiler chickens. A total of 120 male 3 day-old broiler chicks were randomly allocated to CON (control), GK2.5 (ginkgo leaf 2.5%), GK5.0 (ginkgo leaf 5.0%), PK2.5 (pumpkin 2.5%) and PK5.0 (pumpkin 5.0%) of five groups in cages (24 birds per group). All birds were fed corresponding diets from 3 to 35 d of age and determined growth performance and biological parameters including blood biochemical profiles, antioxidant status and intestinal microflora. During the entire feeding trial, GK5.0 and PK5.0 groups resulted in a significantly (P<0.05) higher FCR than GK2.5 and PK2.5 groups. Plasma triglyceride significantly (P<0.05) increased in GK5.0 group compared with the other groups, and the level of alanine transaminase (ALT) increased (P<0.05) in GK5.0 and PK5.0 groups compared with that in PK2.5 group. Dietary addition of ginkgo leaf and pumpkin significantly (P<0.05) increased superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in the small intestine. Also, the addition of 2.5% ginkgo leaf significantly (P<0.05) increased the activities of SOD, GSH-Px and glutathione-S-transferase (GST) in the liver. Futhermore, muscle GST activity significantly (P<0.05) enhanced by dietary addition of ginko leaf and pumpkin. However, the level of lipid peroxidation (MDA) in the small intestine and muscle turned to be higher (P<0.05) in PK5.0 group. The colony forming units (CFU) of E. coli in intestinal digesta significantly (P<0.05) decreased in both ginko leaf and pumpkin supplemented groups compared with CON group. In conclusion, dietary addition of 2.5% ginko leaf and pumpkin as dietary sources can be applicable for the production of high quality broiler chickens.

This study aims at investigating the health and nutritional status of the adults according to frequency of eating out. One day food intake data were collected by 24 hr recall dietary survey and body size, blood pressure and some blood lipids and other constituents were measured on 137 Daejeon metropolitan citizens 20 yrs old and above who visited Chungnam National University Hospital for physical examination during the period of December 6, to December 15, 2008. The frequency of eating out were categorized into four levels: less than once a week, once a week, 2-3 times a week, 4 times a week and above. Body mass Index, waist circumference, blood pressure, blood lipid, blood glucose, GPT and GOT did not showed any significant difference according to the frequency of eating out of the subjects. Though, systolic blood pressures and serum levels of total cholesterol and LDL-cholesterol showed a little tendency to be high in the subjects eating out 2-3 times a week. In the contrary, serum triglyceride level tended to be low in the same group. The subjects eating out 4 times a week and over took more total protein, animal protein, animal fat, phosphorus and vitamin $B_2$ than any other group. Also protein energy ratio was the highest in the group eating out 4 times a week and above and they took more animal food group, other food group, beverages teas and alcohols than other groups eating out. These results showed that higher frequency of eating out leads to higher intake of protein, fat, phosphorus, animal food groups and other food groups (oils, beverages, seasonings) and to lower intake of vitamin C and plant food groups. It, thus, suggested that the strategy for restaurant business is required to provide the menu substituted animal food by more plant food.

This study was conducted to evaluate the efficacy of human milk fortifier (HMF) on growth and nutritional status in growing rats fed infant formula supplemented with HMF. Three week-old male Sprague-Dawley rats were divided into three groups and fed regular formula (RF), premature formula (PF) and regular formula fortified with HMF (RF+HMF) diets for 3 weeks. There was no significant difference in weight gain among groups. However, a significant increase of food intake was observed in PF and RF+HMF groups compared with RF group. With increasing food intake, the intakes of carbohydrate and protein were significantly increased in PF and RF+HMF groups. The weight of perirenal fat was significantly increased in rats fed RF+HMF; however, the weights of liver, kidney and spleen were not significantly different among groups. Although total lipids, total cholesterol, HDL-cholesterol concentrations of serum were not significantly different among groups, triglyceride was significantly increased in PF group. The triglyceride and total-cholesterol of liver were significantly increased in rats fed regular formula fortified with HMF and PF compared with RF group. Glutamic pyruvic transaminase (GPT), glutamic oxaloacetic transaminase (GOT), creatinine (Cre) and blood urea nitrogen (BUN) in serum showed no significant difference among groups. The concentration of growth hormone was significantly increased in PF group compared with other groups. The concentration of hemoglobin was significantly increased in rats fed PF and RF+HMF. These results suggest that the supplementation of human milk fortifier in growing rats may promote growth as increasing food intake and lipid contents in tissues and prevent the anemia of infants.

To evaluate the physiological status of laying flocks, the blood chemistry values were measured and analyzed in various ages under different feeding conditions. Total 671 birds from 48 Hyline brown hens flocks from 13 different poultry farms were bled at the ages of day(s) 1, 11, 21, 50, 80, 120, 180, 240, 300, 400, and 500. The 17 blood chemistries including glucose, lipids, proteins, enzymes, electrolytes and metabolic by-products were measured with an autoanalyzer. Blood glucose showed the highest at the hatching day not relate with the dietary carbohydrates and energy, but tended to decrease during the rest of growth stage in hens. Total blood protein, albumin and globulin increased depending on the ages even though dietary protein was decreased. Blood lipid was greatly changed at different growth stages. Cholesterol was the highest at hatching period and maintained consistently until the 120 days of age. It was increased in birds after 180 days of age. HDL was also highest in hatchery, but decreased greatly after 180 days of age. However, TG was the lowest at one day old, but was increased up to 10 times after 180 days of age compared to that of one day old. The enzyme activities were different. AST, ALT, and GGT showed comparatively contained consistently, whereas amylase was slowly decreased. Blood P, Na, K and Cl showed consistency, but Ca content was increased upto two times of the one day of age. The results from this study showed that the blood chemistry values were affected by the general metabolic status of the host with ages not by feeding conditions. Further, the standard data of age-dependent blood chemistry values in the laying flocks were obtained, which can be utilized for early detection of the changes in the physiological status occurred by the infectious or metabolic diseases. The results of these analyses seemed to be useful to increase the productivity of laying flocks through rapid and proper veterinary medical treatments.

We performed a randomized double-blind placebo-controlled trial to determine whether Laminaria japonica extract (LJE) supplement modulates blood glucose, serum lipids and antioxidant systems in type II diabetic patients. We also measured critical parameters assessing safety in liver and kidney functions after LJE supplement. A total of 37 patients (18 males and 19 females) were randomized to either LJE group or placebo group. The treatment group received four 350 mg of LJE capsules (1.4 g, total) per day for 12 weeks. The placebo group received the same dose of cellulose capsules. Baseline characteristics regarding general life style and dietary intake pattern were similar between the two groups. There were no significant influences of LJE supplement except for waist circumference on anthropometric parameters. As the whole, 12 weeks of LJE supplement resulted in a little decrease in fasting blood glucose (FBG) and glycated hemoglobin (HbA1c), but a significant decrease was not observed. Total cholesterol, LDL-cholesterol and triglyceride concentrations were significantly (p<0.05) lowered in LJE group. The antioxidant enzymes, glutathion peroxidase (GSH-px) and superoxide dismutase (SOD) levels were elevated in the LJE group (p<0.05) compared to the placebo. The increase of these enzymes was associated significantly with the decrease of MDA concentration (p<0.05). Furthermore, LJE supplement showed no adverse effects on the functions of liver and kidney. Findings from this study suggest that LJE supplement can help improve serum lipid status in type II diabetic subjects without adverse effects.

The purpose of this study was to improve and strengthen the function of eel extract prepared with 5 brix eel extract (EE), 5 brix eel and plant mix (black garlic, ginseng, black jujube) 0.35 ml extracts prepared and treated with the extract (EIM-1), and 0.7 ml (EIM-2) divided group. The extracts were administered to rats for five weeks during running training, and the lipid profiles and antioxidant enzyme activities were tested. The lipid content in liver and serum were lower than the normal group difference was not significant between groups. Serum total cholesterol was lower in the experimental group than the control group the mixed extract significantly lower level. HDL-cholesterol levels in the eel extract and eel mixed extract significantly increased by feeding the EIM-1 is 2.0 times, EIM-2 is increased by 2.3 times. Liver glycogen content in the experimental group performed the exercise group compared with the normal control group was significantly lower than in EIM is significantly higher than the control group. The TBARS content in the liver and serum was significantly higher than the normal group was lower than the control group. GOT and GPT were significantly decreased compared to the control group. Hepatic catalase activity was significantly increased in the EIM-1 group, and SOD and GSH-px activities were increased in the EIM-1 and EIM-2 groups. Supplementation with the eel and plant mix extract increased the activities of antioxidant enzymes. Thus, intake of the eel and plant mix extract could improve the antioxidant status and combat different types of oxidative stress.

Four different herbs, including rosemary, oregano, basil and sage, along with green tea were individually added to ground beef at different percentages: 0.5, 1.0, and 1.5, respectively. The sensory qualities of the five natural herbs and their antioxidant effects were evaluated using Beef-Yukwonjeon. For the sensory evaluation results, the 0.5% herb addition and the control group generally showed higher acceptability scores than the 1.0% or 1.5% herb addition groups. In particular, the Yukwonjeon made with 0.5% green tea showed higher preferences in the acceptance tests and ranking tests. However, the sensory differences among samples were reduced after 3 days of storage at $6^{\circ}C$. For the results of lipid oxidation without storage, the TBARS values of the herb addition groups were slightly lower than the value of the control group, but not significantly(p>0.05). However, the antioxidant effects of each herb showed higher values over a longer storage period as well as at the higher herb concentrations. The antioxidant effects of the herbs during 7 days' of storage at $6^{\circ}C$ were evaluated as $10.0{\sim}38.5%$ reductions in TBARS values as compared to the group without herbs. Furthermore, the antioxidant effects of the herbs during 30 days' of storage at $-20^{\circ}C$ were shown as $16.8{\sim}27.8%$ reductions in the TBARS value. The green tea showed the highest antioxidant activity against lipid oxidation, because it was acceptable at higher concentrations in the sensory evaluation. These results indicate the potential to produce better quality beef-Yukwonjeon, with herbs, especially green tea.

This study was designed to investigate the effects of enzymatic hydrolysates (EH) from Hamcho (Salicornia herbacea L.) on blood glucose and serum lipid status in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into normal and 5 diabetic groups. The diabetic groups were fed enzymatic hydrolysate-free control (DM) diets or diets supplemented with 0.02% (DM-2), 0.04% (DM-4), 0.08% (DM-8), and 0.16% (DM-16) of enzymatic hydrolysate for 4 weeks. Body weight gains were lower in five diabetic groups than that of the normal group. Blood glucose was decreased in EH-supplemented groups as compared to the normal group, and especially the lowest blood glucose levels were found in DM-4 and DM-8 groups. Activities of three disaccharidase in the middle part of the intestine, such as maltase, sucrase and lactase, in EH-supplemented groups were significantly lower than those of DM group. There was no significant differences in the activities of glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) among all experimental groups. Serum triglyceride in DM group was significantly increased as compared to the normal group, but those of EH-supplemented groups were decreased to the normal level. Total cholesterol level in DM group was higher than EH-supplemented groups and normal group, but that of DM-16 group was significantly decreased to the normal level. HDL cholesterol level in DM group was significantly decreased compared to the normal group, but that of EH-supplemented groups was increased to the normal level. These results suggest that enzymatic hydrolysate from Hamcho has hypoglycemic and hypolipidemic effects on STZ-induced diabetic rats and may be useful as a dietary supplement for the treatment of diabetes.
