본 연구에서는 12주간 중년 비만여성을 대상으로 체중조절 프로그램 (영양교육 및 상담, 운동요법)을 실시하여 식습관, 혈액성분, 체성분의 변화를 살펴보고자 하였다. 영양 교육실시 후 식습관에서는 식사의 규칙성, 간식섭취횟수, 외식횟수 및 식사속도 등이 긍정적으로 개선되었다. 혈액지질 성분과 혈압에서는 총콜레스테롤, 중성지방, LDL-콜레스테롤, 수축기 혈압이 유의적으로 감소하였으며, 동맥경화지수와 이완기 혈압도 유의적인 차이는 없었지만 감소하였다. 비만지표인 BMI와 WHR (허리-엉덩이 둘레비)이 유의적으로 감소되어 체중이 감량됨을 알 수 있었고 체지방률, 지방량도 유의적으로 감소되었으며, 근육량은 유의적인 차이는 없었지만 약간의 증가를 가져와서 장기적으로 체성분의 긍정적인 변화를 기대할 수 있었다. 이상의 결과를 미루어 효율적인 비만관리를 위해서는 획일적인 방법보다는 대상자들의 특성을 고려하여 식행동 개선에 초점을 맞춘 영양교육 및 상담과 아울러 운동요법을 병행하여관리가 이루어져야 할 것으로 생각된다. 그러기 위해서는 각 영역의 전문가들의 긴밀한 협조와 노력으로 실질적인 건강향상을 위한 체계적인 비만관리 프로그램이 이루어져 비만을 예방하고 건강지표 향상을 가져와 국민건강 증진에 도움이 될 것으로 본다.

To elucidate the effects of an obesity control program on body composition and serum lipid levels, 31 obese elementary students (male: 25, female: 6) residing in the Gyeonggi area were evaluated and their body composition, serum total cholesterol, HDL-cholesterol, LDL-cholesterol and TG (triglyceride) were analyzed. The average age, height, weight and BMI (body mass index) were $11.52{\pm}1.00\;yrs$, $151.96{\pm}8.04\;cm$, $68.21{\pm}9.03\;kg$ and $29.40{\pm}1.79\;kg/m^2$ for the males, respectively, and $11.17{\pm}1.17\;yrs$, $147.83{\pm}5.15\;cm$, $65.05{\pm}10.86\;kg$ and $29.62{\pm}3.24\;kg/m^2$ for the females, respectively. There was a significant decrease in BMI for males (p<0.001) and females (p<0.05). There were also significant changes in all of the biochemical levels evaluated before and after the study. Specifically, the total cholesterol, LDL-cholesterol and TG level decreased after the obesity control program, while the HDL-cholesterol level increased after the program. These results indicate that obesity control programs do change the BMI, serum total cholesterol, HDL-cholesterol, LDL-cholesterol and TG levels in obese elementary students. Thus, obesity control programs are urgently needed to prevent degenerative disease and decrease obesity among children in elementary school.

Background: There is abundance of studies on the decrease in body fat through limited calorie intake or exercise; however, studies focusing simultaneously on functional foods and exercise are rare. This study was aimed to identify the effects of combination of a functional beverage and exercise on body composition and biochemical metabolic profiles. Method: Eighty-one healthy volunteers (69 females aged 19 to 50 years and 12 males aged 19 to 55 years), who maintained their body weight stable with 23 or higher in BMI (kg/$m^2$) and 25% or higher body fat for the last three months, were recruited in the study through written advertisement. All the subjects gave their informed consent, and the study was conducted in accordance with the Declaration of Helsinki. The study design was a randomized double-blind placebo-controlled parallel group design. All participants were given 12-week programed-exercise, which was performed 3 times a week. One bottle (100 ml) of test (Garcinia cambogia 300 mg, L-carnitine 20 mg, Soy peptide 1,000 mg) or placebo solution was given daily 30 min before each session of programed-exercise. BMI (body mass index), %fat, local fat amount (visceral and mid-thigh), waist circumference, skin fold thickness and some biochemical metabolic parameters like glucose, insulin and free fatty acids, etc in the blood were measured and compared before and after 12-week intervention within groups as well as between groups according to the protocol Results: Twenty six volunteers were dropped out and fifty five volunteers completed the study. At the end of 4, 8, and 12 weeks, approximately 1.98%, 3.00% and 3.50% losses of initial body weight were observed, respectively, in the test group (P<0.01), and 0.29, % ,0.74%, 1.60%, respectively, in the placebo group (P>0.05). BMI changed by 2.40%, 3.41% and 4.46%, respectively, in the test group, and 0.38%, 0.95% and 1.75%, respectively, in the placebo group, at each period of time. The reductions of body weight and BMI were significantly higher in the test group than in the placebo group at each period of time (P<0.05). Conclusions: It is thought that the combination of functional beverage, which contains mostly garcinia cambogia, L-carnitine, and soy peptide, and exercise have synergy effects on reducing body fat.

Objectives: This study is designed to verify the effects of Mannyeon-hwan (MNH) on acetic acid-induced colitis in rats. Methods: Colitis was induced in male Sprague-Dawley rats weighing approximately 250 g by injecting acetic acid through the anus. The rats were classified into four groups: normal group, acetic acid (AA) group, AA+MNH (L) (low concentration) group, and AA+MNH (H) (high concentration) group. The body weight, visual evaluation of the colonic mucosa, anatomical histological changes, and changes in the expression of cytokines in the colon tissue were compared and analyzed. Results: Compared with the normal group, weight loss was observed in mice induced with colitis. Compared with the AA group, weight loss recovery occurred in the AA+MNH (L) and AA+MNH (H) groups, and significant changes were observed after the sixth day. In the visual evaluation of the colonic mucosa, a significant decrease in damage indicators was observed in the AA+MNH (L) and AA+MNH (H) groups compared with the AA group. In terms of anatomical histological changes and changes in the expression of tumor necrosis factor-α and interleukin-6 in colon tissue, a significant decrease was observed in the AA+MNH (L) and AA+MNH (H) groups compared with the AA group. A more pronounced decrease was observed in the AA+MNH (H) group compared with the AA+MNH (L) group. Conclusion: The effects of MNH on colitis were confirmed through research. MNH can be used as a first-line treatment for patients complaining of colitis who visit oriental medicine clinics.

In order to understand the influences of wearing clothings with different thermal insula-tions when men were exposed from $25^{\circ}C$ environment to 18$^{\circ}C$ environment, thermoregulatory responses were measured on 4 healthy female college students. Subjects rested wearing T-shirts, trousers, and socks called LC(total weight 541g) at 25$\pm$1$^{\circ}C$, 50$\pm$5% R.H. and then exposed to the room conditioned in 18$\pm$1$^{\circ}C$, 50$\pm$5$^{\circ}C$ R.H. with LC as it was(LC Type) or with T-shirts, trousers, socks, training wear upper garment, the training wear lower garment called HC (total weight 1368g)(HC Type) for 120 min. The results can be summarized as follows: 1) When subjects were exposed from $25^{\circ}C$ environment to 18$^{\circ}C$ environment, decrease of rectal temperature was significantly smaller in LC Type than in HC Type. 2)Increase of heat production and weight loss had no significant difference between two types of clothing. 3)Internal thermal conductance was higher in HC Type and external thermal conductance was higher in LC Type. Therefore total thermal conductance was higher in LC Type than in HC Type. 4)Decrease of skin temperature was greater in LC Type than in HC Type. 5)Subjects felt colder with LC Type than with HC Type, but did not feel differently in comfort sensation between two types of clothing. It was suggested that less decrease of rectal temperature in LC type inspite of more dry heat loss from body might be ascribed to a shift of blood from the shell area to the core area originating in the vasoconstriction and the lowered internal thermal conductance. In conclu-sion, the importance of the state of internal heat distribution in the homeostasis seemed to be reaffirmed.

This study was performed to evaluate the effects of dietary vitamin levels on physiological responses, blood profiles, and reproductive performance in gestating sows. A total of 52 F1 multiparous sows ($Yorkshire{\times}Landrace$) with an average body weight of $223.5{\pm}31.7kg$, an average parity of $6.4{\pm}2.7$, and an average backfat thickness of $18.5{\pm}4.9mm$ were divided into four treatment groups considering body weight, backfat thickness, and parity in a completely randomized design with 13 replicates. The treatments were 100% (V1), 300% (V3), 600% (V6) and 900% (V9) of the National Research Council (NRC) Nutrient Requirements of Swine. The gestation diet was formulated based on corn-soybean meal (SBM) and contained 3,265 kcal of metabolizable energy (ME)/kg and 12.00% crude protein. During the lactation period, all sows were fed the same commercial lactation diet. There was no significant difference in body weight of gestating sows. However backfat thickness tended to increase when higher levels of vitamins were provided to gestating sows (p < 0.10). When high levels of dietary vitamins were provided, the body weight change of lactating sows increased (p < 0.01). When sows were fed higher levels of vitamins, the feed intake of lactating sows tended to decrease (p = 0.06). There were no treatment differences in the number of total born, born alive, stillbirth piglets, or the body weight of piglets according to different dietary vitamin level. As dietary vitamin level increased, the serum concentration of $25(OH)D_3$ in sows at 90 days of gestation linearly increased (p < 0.01). Furthermore, the serum vitamin E level of gestating sows was linearly increased with increasing dietary vitamin level (p < 0.05). The current NRC vitamin requirements are sufficient for gestating sows and higher levels of vitamins in the gestation diet did not show any beneficial effects for gestating and lactating sows.

This experiment was undertaken to investigate the effect of administration of Agyoju or Mokhyang on the maintenance of pregnancy, delivery and sex ratio in the mice in different gestation periods. Adult female mice were administered orally at three different periods, from ovulation to implantation (Exp.1), from post-implantation to organogenesis (Exp.2), and from fetal growth to parturition (Exp.3). In Experiment 1, number of fetus implanted and mean body weight were not significantly different. However, the delivery of male offspring was significantly increased in Agyoju and Mokhyang administrated groups than control group. In Experiment 2, the number of fetuses implanted, live offsprins and their body weight at delivery were significantly increased in the Agyoju administered group than Mokhyang and control groups. In Experiment 3, the number of live offspring and sex ratio were not different in both treatments and control group. However, mean body weight at delivery was significantly increased in both treatment groups than that of control group. These results suggest that 1) Agyoju and Mokhyang have beneficial effects in maintenance of pregnacy, and that 2) The action of unknown component(s) in Agyoju may be related to selection of male spermatozoa for fertilization in vivo, and that 3) the administration of Agyju of Mojhyang during mid-and late-pregnance periods were shown the increment of body weight of live offspring without decrease of litter size.

High-protein fermented whey beverage (FWB) was manufactured using whey protein concentrate (WPC) and Lactobacillus plantarum DK211 isolated from kimchi. This study was designed to evaluate the anti-obesity activity of FWB in male rats fed a high-fat diet. Male Sprague-Dawley rats were randomly assigned to three groups (n=8 per group). The three groups differed in their diet; one group received a normal diet (ND), another, a high-fat diet (HD), and the third, a HD plus fermented whey beverage (HDFWB), for 4 wk. Supplementation with FWB (the HDFWB group) prevented weight gain and body fat accumulation. The food intake in the HDWFB group was significantly lower (p<0.05) than that of the HD group. The HDWFB group also showed a significant decrease in organ weights (p<0.05), except for the weight of the testis. There was a significant decrease in total cholesterol, LDL-cholesterol, and triglycerides in the HDFWB group compared with the HD group (p<0.05), but there was no significant difference in serum HDL-cholesterol levels among the experimental groups. Rats ingesting FWB (the HDFWB group) also showed a significant decrease in blood glucose levels, and plasma levels of insulin, leptin, and ghrelin compared to HD group (p<0.05). These results indicate that FWB has beneficial effects on dietary control, weight control, and reduction in fat composition and serum lipid level; consequently, it may provide antiobesity and hypolipidemic activity against high fat diet-induced obesity in rats.
