This study was conducted to investigate the effect of an uncooked powdered food(UPF) on the weight loss and changes of the biochemical nutritional status for 20 overweight and 26 obese women in Iksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Also anthropometric and biochemical measurements before and after the UPF program were estimated. The intake of energy, lipid and protein decreased and the quality of meals improved as people started to take UPF. Due to the energy loss by taking UPF, weight and body fat decreased significantly. The percentage of the body fat was high among the weight lost, from which we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening the body fat. The most positive change among biochemical changes by taking UPF was the decrease of serum lipid contents. When overweight and obesity women replaced two out of three meals with UPF for 3 month period, no significant nutritional problems occurred. It seems that the 12weeks of UPF program used in this study was effective in improving anthropometric indices without producing the deficiency of iron or other susceptible nutrients.

In this study, anthropometric and biochemical indicators and related factors for community dwelling elderly living alone (ELA). as well as for elderly not living alone (ENLA) were explored. The subjects were 140 elderly females (70 living alone, 70 not living alone) residing in Bucheon. Anthropometric measurements revealed significant differences between the two groups (ELA/ENLA) for height, weight, BMI, triceps skinfold thickness, suprailiac skinfold thickness, subscapular skinfold thickness, and body fat percentage. The ELA showed significantly lower data for most of the anthropometric indices, except PIBW. Biochemical indicators of iron status (hemoglobin, serum iron, transferrin saturation) were significantly lower for the ELA, whereas the total serum cholesterol, LDL-C, LDL-C/HDL-C, for the ELA were significantly higher. The prevalence of hypercholesterolemia (240 mg%) was 30%. The latter three are not in accordance with general malnutrition among the ELA. The hemoglobin of the ELA was positively correlated with energy, fat, iron and cholesterol intake, but negatively correlated with height. The serum cholesterol of the ELA was Positively associated with most of their nutrient intake.

This study was due to investigate the dietary intakes, serum lipids and other hematological indices in female adolescent smokers. The subjects were 85 smokers, whose average pack-year(smoking years on the basis of one pack of cigarettes per day) was 1.26 and 87 nonsmokers who were female high school students in Seoul. An anthropometric measreument was performed and % body fat was also analyzed by the Bioelectrical Impedance Fatness Analyzer(GIF-891). Dietary intakes and food habits were examined through questionnaires and nutrient intakes were analyzed by the Computer Aided. Nutritional analysis program for professional(CAN-pro). Serum TG, HDL-cholesterol and total-cholesterol levels were measured with test kits. Serum glucose, albumin, GOT and GPT were measured by automated dry chemistry system, SPOTCHEM 4410. Hemoglobin, hematocrit, RBC, WBC and MCV were determined by Semi Automated Microcell Counter(F-520). All data were statistically analyzed by SAS PC package program. There was no significant difference in the anthropometric measurements between smokers and nonsmokers. The caloric intake in adolescent smokers tended to be higher than that of nonsmokers but the difference was not statistically significant. In addition, there was no significant difference between smokers and nonsmokers in biochemical indices. Analysis of serum lipids showed that the serum levels of total-cholesterol and LDL-cholesterol of nonsmokers were unexpectedly significantly higher(p<0.05) than those of smokers. Overall results indicate that smoking itself with short pack-year in healthy female adolescent did not seem to influence apparent health and nutritional status.

Malnutrition is a common problem in patients undergoing maintenance hemodialysis (HD) and compromised food intake is an important cause. Malnutrition is one of the important factors influencing mortality in these patients. This study was conducted to evaluate the effectiveness of nutrition education at improving nutritional status of 23 Korean HD patients (mean : 48.6 $\pm$ 10.4 years, men : 8, women : 15). Anthropometric indices, nutrient intakes, and biochemical blood indices were measured before and after a 6-month nutrition education intervention. Anthropometric indices such as percent ideal body weight [PIBW (%)], body fat, body mass index (BMI), mid-arm circumference (MAC), mid-arm muscle circumference (MAMC), and calculated arm muscle area (CAMA) of subjects were within the normal range and not changed by nutrition education. Subjective global assessment (SGA) was significantly increased (p < 0.05) after nutrition education. Intake of total energy, carbohydrate, lipid, Ca, and vitamin B1 was increased significantly (p < 0.05) but intake of phosphorus, potassium, and sodium was decreased (p < 0.05). The serum concentrations of albumin, total protein, and Ca were significantly increased (p < 0.05), but levels of P and K were decreased (p < 0.05) after the intervention. These findings suggest that nutrition education for HD patients can be effective for positively changing nutrient intakes, leading to improvements in blood indices and nutritional status.

The purposes of this study were to investigate the effects of drug use & the health-related habits(alcohol drinking, smoking and exercise) on the nutritional status of elderly. subjects were 362 free-living elderly aged over 65(male 131, female 231) in Chungbuk area. Interviews with questionaire on drug use, health-related habits, and nutrient intakes, anthropometric measurement and biochemical blood test were carried out from August to October in 1996. Energy intakes of the males who used drug were lower than those of males who did not use any drug, while energy intakes of the females who used drug were higher than those of females who did not. In biochemical indices, LDL-cholesterol level of the males who used drug was higher than that of males who did not have drug. serum triglycerides, VLDL-cholesterol and obesity degree(BMI & TS) of the females who used drug were higher than those of females who did not have drug. Alcohol drinking, smoking and exercise habits of the elderly who used drug had little effects on the nutrient intakes while those habits had considerable effects on biochemical indices and obesity degree. Among drug users, male drinkers showed higher triglycerides & HDL-cholesterol level, and female drinkers showed higher triglycerides and lower total cholesterol and LDL-cholesterol level, compared to non drinkers. Among female drug users, smokers showed lower body mass index(BMI) compared to non smokers. Males and females who had both drinking and smoking habits showed higher serum triglycerides and VLDL-cholesterol level. Especially females who had both drinking and smoking habits showed lower BMI & Tricep skinfold thickness compared to those who had netiher drinking nor smoking habits.

This study was done to investigate the nutrient intakes and plasma biochemcial indices in 68 female college students according to their skin types. Nutrient intakes were investigated by quick estimation. The plasma TG and total cholesterol levels were measured by the Spotchem sp-4410. The plasma levels of retinol and $\alpha$-tocopherol were measured by HPLC. In addition, the activities of antioxidant defense enzymes such as plasma glutathione peroxidase(GSH-Px) and glutathione reductase(GHS-Rd) were determined. All data were statistically analyzed by SAS PC package program. The results of this study were as follows : The average age, height, weight, BMI, systolic blood pressure and diastolic blood pressure ofthe subjects were $20.9{\pm}1.9yr, 160.7{\pm}4.3cm, 53.0{\pm}7.1kg, 20.5{\pm}2.4kg/m^2, 105.3{\pm}11.5mmHg and 70.6{\pm}7.7mmHg$, respectively. Ten students(14.7%) had normal skin type, 19 students(27.9%) had dry skin type, 11 students(16.2%) had oily skin type, 17 students(25.0%) had acne and 11 students(16.2%) had mixed skin type. The intakes of energy and fats in oily skin group were significantly higher(p<0.05) than those of the dry skin group, but vitamin C intake in the mixed skin group was significantly higher(p<0.05) than those of the dry skin group, but vitamin C intake in the mixed skin group was significantly lower(p<0.05) than that in other skin types. The intakes of other nutrients were not significantly different among skin types. The analysis of lipids showed that the plasma total-cholesterol level of mixed skin group was significantly lower(p<0.05) than that of the oily skin group, whereas other lipid levels were not significantly different. The other parameters such as retinol, $\alpha$-tocopherol, GSH-Px and GSH-Rd of plasma were not significantly different among skin types. Overall results indicate that dietary intake pattern may influence skin type and thereby some blood biochemical indices can be different by skin types.

Thermal stress is a tremendous health predicament encountered by poultry farmers with adverse effects on the performance, product stature, health condition, survival, and overall welfare of poultry birds, and so requires urgent dietary user-friendly strategy to curb. This study was conducted with 200-day old broilers for the purpose of investigating the potential of phytogenics in refining the negative effects of heat stress on broiler chicken. Moringa, Phyllanthus and mistletoe leaves were processed as phytogenic supplements and incorporated into standard ration for broilers as treatments B1 (control), B2, B3 and B4 diet during the peak of thermal discomfort in humid tropics. Growth and carcass indices were monitored in a 49-day trial and blood samples were harvested at the end of the ordeal period to assess haematology, serum biochemical and oxidative stress markers with the use of standard procedures. The results obtained showed that the prevailing environmental condition in the study site indicated that the birds were exposed to heat stress. Birds fed on moringa and mistletoe supplements had higher performance index than birds without supplementation during heat stress condition, while birds fed on mistletoe supplement had the highest survival rate across the treatments. The liveweight, slaughter weight, dressed weight and eviscerated weight of heat stressed birds fed on moringa, phyllanthus and mistletoe supplements were significantly higher than birds on control treatment. Heterophyl/lymphocyte ratio of heat stressed birds without supplement were higher than birds on phytogenic supplements, with least values recorded in phyllanthus and mistletoe fed birds. Birds on phytogenic supplement tend to have lower cholesterol profile, lipid peroxidation and better antioxidant profile than birds on control treatment during heat stress conditions. Mistletoe supplementation in broiler ration enhances the survival rate, as well as promotes growth indices better among the phytogenic supplements. However, phytogenic supplements did ameliorate the negative effects of thermal discomfort on performance, physiological and oxidative stress in heat-stressed broiler chicken.

Changes of plasma DNA contents and serum biochemical values were measured in rats administered with $HgCl_2$ to investigate the in vivo cytotoxic effects of mercury and examine the usefulness of these changes as indicators of mercury exposure and diagnosis of mercury poisoning. Rats were given once intraperitonealy $HgCl_2$(0.13. 0.32. 0.8 and 2 mg/kg b.w) and the changes of plasma DNA contents and serum biochemical values were measured at the time of 2, 4, 8, 24, 48 and 72 hours after the administration of $HgCl_2$. Plasma DNA contents began to increase from 2 hours after the administration of $HgCl_2$ in all the treatment groups significantly compared to control with dose-dependent pattern. The levels of plasma DNA reached to peak at 48 hours as 2.77, 7.60, 15.46 and 16.51 times higher than control in each treatment group of 0.13, 0.32, 0.8 and 2 mg/kgb.w, respectively and remained to be higher until 72 hours after the administration. The values of creatine kinase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, blood urea nitrogen and glucose of serum were increased, however the values of alkaline phosphatase, total protein and triglyceride were decreased. These changes of increase and decrease showed dose-dependent pattern but the starting time, maintenance and magnitude of change were various and characteristic according to serum biochemical indices. Among the changes of serum biochemical values, those of aspartate aminotransferase, lactate dehydrogenase and blood urea nitrogen were apparently and significantly increased compared to control from 2 to 72 hours by the administration of 2 mg/kg $HgCl_2$. This study demonstrates that plasma DNA and serum biochemical values such as aspartate aminotransferase, lactate dehydrogenase, blood urea nitrogen and etc. are valuable as biomarkers for mercury exposure assessment and diagnosis of mercury poisoning.

서로 다른 고도에서 사육하고 있는 2-3세령의 수컷, 건강한 비육 한우를 세 그룹(600 m, n=50; 200-400 m, n=58; 0 m n=49)으로 나누어 혈액 및 혈청검사 그리고 면역항체가 검사를 실시 하였다. 고도를 제외한 일반 사육 환경과 식이 및 축사의 형태는 매우 비슷한 조건이였으며 질병이 확인 된 개체는 통계에서 제외 하였다. 경정맥에서 채취한 혈액은 일반혈액검사 중 WBC, RBC, Hb, PCV 를, 혈청화학검사 중 AST, LDH, TBL를 집중적으로 비교 분석하였으며 또한 면역학적 검사를 실시하였다. 고도가 높은 그룹이 낮은 그룹에 비하여 CBC에서는 조금 높게 나타났으며, 혈청검사에서는 평지에서 사육된 한우가 조금 높게 나왔다. 그러나 모두가 정상범위를 벗어나거나 통계적으로 유의한 수준의 차이를 보이지 않았다. 이러한 결과는 지금까지 알려진 대부분의 연구결과와는 차이가 있는 것이다. 본 연구와 지금까지의 알려진 연구와의 이러한 차이는 과거의 연구들은 고도의 차이가 현저한 경우가 대부분이었으나 본 연구에서 조사한 지역은 서로 고도가 비슷한 점에서 생긴 결과라고 여겨지며, 특히 고도가 600m 이하인 지형에서는 서로 큰 영향을 받지 않는 것으로 생각된다. 따라서 한우의 경우 목장 시설의 건축시 지형에 따른 어려움과 주변에서 들여오는 조사료의 수송에 따른 경제적 불리, 축산폐수 처리는 물론 퇴비의 활용 등 전반적인 목장 관리 면에서 고도가 높은 산지 보다는 평지가 권장된다.

Objective: The study was conducted to evaluate the effects of different methionine (Met) sources on production performance, reproduction performance, egg quality and serum biochemical indices in broiler breeders. Methods: After receiving a basal diet (containing 0.25% Met) for a 2-wk pretreatment period, a total of 360 39-wk-old Lingnan yellow broiler breeders were randomly allocated to four treatments with six replicates each (15 birds per replicate). Breeders were fed with basal diets (control) or diets supplemented with DL-methionine (DLM), DL-2-hydroxy-4-methylthio butytric calcium (MHA-Ca) and coated DL-Met (CME) respectively. Results: The results showed that CME supplementation promoted laying rate and decreased feed-to-egg ratio (F/E) (p<0.05), DLM and MHA-Ca supplementation decreased F/E (p<0.05) when compared with control group. The rate of fertility, hatchability and birthrate were higher (p<0.05) in DLM, MHA-Ca, and CME groups than control group. Compared with control group, CME increased the eggshell thickness (p<0.05); MHA-Ca improved the eggshell thickness, shell ratio and eggshell strength (p<0.05). Results also showed that CME elevated the concentration of total protein in serum (p<0.05); MHA-Ca improved the concentration of calcium in serum (p<0.05). The concentration of serum uric acid in DLM, MHA-Ca, and CME groups was lower than that in control group (p<0.05). Besides, CME had higher concentrations of serum taurine, cysteine and cystanthionine (p<0.05) while MHA-Ca and DLM promoted the serum taurine concentration (p<0.05) compared with control group. Conclusion: Based on the results, it was concluded that Met supplementation could enhance the production and reproduction performance as well as the antioxidant status and egg quality of broiler breeders. In terms of improving the production performance, reproduction performance and antioxidant performance, CME was superior to DLM and MHA-Ca; but in regard to the enhancement of eggshell quality and serum Ca concentration, MHA-Ca was superior to DLM and CME.
