The purposes of this study were to observe the effects of the exercise programs which have different order of walking and resistance exercises on the composition of the abdominal fat and the blood lipid profiles of the obese college women and to provide basic materials for the development of more effective and more efficient exercise program in order to reduce and prevent obesity. Classification of group, "A" group(resistance exercise after aerobic exercise) is a group of 12 people, "B" group(resistance exercise after aerobic exercise) is a group of 12 people. To determine the abdominal fat, intestine fat area, subcutaneous fat area, ratio of intestine fat area/subcutaneous fat area were analyzed, while for the blood lipid profiles, total cholesterol, triglyceride, high density lipid protein, and low density lipid protein were analyzed. First, there was statistically significant difference in the interaction in the abdomen subcutaneous fat. In the post analysis, the Resistance first group showed significantly more reduction to confirm that there was difference according to the order of the exercises. Second, there was statistically significant difference in the interaction effects in the factor of triglyceride. In the post analysis, the Resistance first group only showed significant reduction in the triglyceride to confirm that resistance exercise followed by aerobics would be better for the reduction of the triglyceride.

Vitellogenins(VTGs) are the precursor of egg-yolk proteins in most oviparous species from invertebrates to vertebrates. In oviparose vertebrates, VTGs are synthesized in the liver and transported through the blood to oocytes. In female fish, concentrations of plasma VTG increase rapidly at onset of vitellogenesis in the normal reproductive cycle. Male fishes also possess the gene for VTG, but plasma concentrations of the protein typically remain small, presumably due to low levels of endogenous estrogens. However, exposure of males to exogenous estrogenic mimics can result elevated. Therefore, the VTG in fish can be used as a useful biomarker for appropriate tools of endocrine disrupting compounds effects. In this studies, we prepared the test methods that can measure the plasma VTG level in the gobies that live in polluted area with mimic estrogen. For the purpose, we purified VTG of floating goby(Chaenogobius annularis) and prepared specific monoclonal and polyclonal antisera to yolk protein, then developed a sandwich competitive ELISA system for measurement of plasma VTG levels. Validation for the ELISA system using monoclonal and polyclonal antibodies against VTG was tested. The absorbance curve of serial dilutions of serum from vitellogenic female was paralleled to the standard curve of VTG, but normal male was not paralleled. The developed sandwich ELISA system was measured for VTG levels in plasma of common goby(Acanthogobius flaviman) and javeline goby(A. hasta) as well as in plasma of floating goby(C. annularis).

본 연구의 목적은 한우 난포발달에 있어서 난포액 및 anti-inhibin serum의 생리적 역할을 검토하기 위해 수행하였다. Anti-inhibin serum(AI)은 항원으로서 porcine inhibin-$\alpha$-subunit 19~32의 peptide를 사용하여 adjuvant 용액을 1:3의 비율로 혼합하여 앙고라종 토끼 5두(체중 2.5kg)에게 주 2회 간격으로 접종 후 얻어진 항혈청을 사용하였다. 난포액(bFF; bovine follicular fluid)은 도축장에서 도축되는 한우 난소로부터 직경 1.0cm 이하의 난포로부터 회수하여 스테로이드를 제거하기 위해 10% chacoal so lution(50 mg/$m\ell$, Norrit-A, Fisher Sci., USA)을 처리하여 45분간 배양후 원심분리후 상층액을 회수하여 실험에 공시하였다. 공시동물은 1산후 정상적으로 발정주기가 반복되는 한우암소 9두를 난소감정후 황체를 확인하여 PGF2$\alpha$제제(lutylase. USA)를 주사하여 발정을 유기한 다음, 난소의 first wave가 시작되는 시기인 배란직후 12시간째부터 4일간 일일 2회 5 $m\ell$씩 총 8회 40 $m\ell$의 AI와 bFF를 각각 경정맥으로 주사하였으며 대조구로서 생리식염수를 주사하였으며 채혈 및 정맥주사를 용이하게 하기 위해 경정맥에 카테타를 설치하여 6시간간격으로 총 200시간까지 채혈하였으며 초음파진단기를 이용하여 난포의 발달을 검토하였다. 채혈후 혈중Inhibin, progesterone 및 Estrad iol-17$\beta$농도의 분석은 RIA 및 ELISA법으로 분석하여 얻어진 결과는 다음과 같다. 혈중 Progesterone농도는 대조구와 AI처리구에서는 배란후 68시간째부터 유의적으로 증가하기 시작하였으나, bFF처리구에서는 배란후 68시간부터 170시간까지 대조구에 비해 유의적으로 낮은 농도를 나타내었다. 이에 반해 혈중 Estradiol-17$\beta$농도는 대조구의 경우 bFF처리구와 비슷한 수준으로 배란후부터 낮은 농도를 유지하였으나, AI 처리구는 배란후 36시간이후부터 108시간까지 유의적으로 높은 수준을 유지하였다가 그 이후 감소되었다. 한편, 혈중 Inhibin농도는 전 구간에서 배란후 84시간까지 불규칙한 농도를 보이다가 bFF처리구에서는 배란후 84시간부터 유의적으로 증가하였다. 배란후 72시간째에 초음파진단기를 이용하여 난소의 난포발달을 조사한 결과 , 대조구와 bFF처리구에 비해 AI처리구에서 발달난포가 유의적으로 많은 것을 확인하였다. 이상과 같은 결과로, Anti-inhibin serum은 한우 자체에서 분비하는 Inhibin을 특이하게 억제하여 Inhibin에 의해 억제되는 FSH분비가 촉진됨으로써 난포발달과 estrogen의 농도가 촉진되는 것으로 사료되어 anti-inhibin serum이 한우의 과배란유기 효과가 있는 것으로 사료된다.

The purpose of this study was to the effects of exercise intensities in physical activity of 8 weeks, on fitness, blood lipid for middle school students with intellectual disabilities. Participants of the research were allocated by low-intensity(n=8, 40~54%HRR), middle-intensity(n=8, 55~69%HRR), and high-intensity(n=9, 70~85%HRR) exercise groups wirelessly. For setting and maintenance of individual exercise intensity, wireless heart rate monitor(RS-400, POLAR, Finland) was used. Fitness, BDNF, and blood lipid were measured equally before participating in physical activity and 8 weeks after participation. As a result, fitness and agility of high-intensity exercise group were significantly increased than low-intensity exercise group. BDNF of high-intensity exercise group was also significantly increased than low-intensity exercise group. For blood lipid, only total cholesterol showed differences by exercise intensity group and exercise group more than middle intensity showed significant reduction. In conclusion, when giving same exercise to middle school students with intellectual disabilities, fitness and BDNF were increased the mostly in high-intensity exercise group and total cholesterol was effective from the exercise of more than middle intensity.

The seven (7) housewives were used as subjects at three times per weeks for twelve (12) weeks in order to find out the effects of aerobic exercise and weight training on body composition and blood lipid. Each subject's weight, lean body mass, percent body fat, BMI and blood lipid were measured immediately after the training and the results compared with the same prior to exercises were obtained as follows ; 1. The weight and percent body fat of the subjects were slightly but not significantly decreased, however the lean body mass following training was significantly increased with 1.3 %. BMI S RBW were also not significantly decreased. 2. Calory intake was 1929.9 cal before the training and 1896.0 cal after the training, which doesn't shows much difference. 3. The blood lipid such as TC and LDL-C were a little increased after the training, but HDL-C shows significant increase of 22.7 %, and HDL-C/TC was significantly increased with 13.2 % (p<.05 ) as well. However, TG shows significant decrease (p<.05 ).

We investigated the anti-obesity effects of Ishige okamurae extract (IOE) on body weight, epididymal adipose tissue weight, plasma lipid levels, and leptin levels in high-fat diet (HFD)-induced obese mice. After inducing obesity by feeding 45% HFD for 4 weeks, C57BL/6J mice were randomly assigned to HFD or HFD containing 5% IOE, and then fed for 6 weeks. The body weight and epididymal adipose tissue weight were increased by HFD, but they were significantly less in animals fed HFD containing 5% IOE than in those fed HFD. Levels of plasma triglyceride, total cholesterol, and LDL-cholesterol were significantly lower, but the HDL-cholesterol level was significantly higher in animals fed HFD containing 5% IOE compared with the HFD group. The plasma leptin level was significantly lower in animals fed HFD containing 5% IOE. The diet containing 5% IOE did not show any adverse effects on liver and kidney functions. These results suggest that IOE has a potential as anti-obesity agent by reducing body weight and lowering the levels of obesity-related factors in plasma.

We investigated the effect of Rhus verniciflua Stokes extract ingestion with exercise training on plasma lipids and insulin resistance for 8 weeks. Forty SD (Sprague-Dawley) male rats were used as the experimental animals that were divided into CON (control), RVS (Rhus verniciflua Stokes), EXE (exercise training), and RVS-EXE (Rhus verniciflua Stokes with exercise training), respectively. Body weight gain in EXE (202%) and RVS-EXE (203%) was significantly lower than CON (253%) and RVS (239). Stored fats were significantly lower with RVS and/or exercise training. Blood lipids were enhanced in RVS and RVS-EXE compared to CON. Blood glucose was significantly high in CON compared to the other groups. Insulin and HOMA index has the same tendencies with glucose, however, the synergic effect was found in RVS-EXE. In conclusion, Rhus verniciflua Stokes extract ingestion with exercise training has the effect of lowering amount of stored fats, reducing blood lipids, and enhancing insulin resistance, therefore, metabolic syndrome, diabetes, obesity, and hyperlipidemia might be prevented.

The objective of this study was to investigate the effects of administration methods for on Garcinia cambogia on blood Garcinia cambogia concentration and antioxidative levels. Rats were divided into three groups: G1 (normal group), G2 (one administration of Garcinia cambogia extract 2,800 mg/kg b.w.), G3 (three separate administrations every 6 h of Garcinia cambogia extract 750, 850, and 1,200 mg/kg b.w. for 18 h). Blood samples were collected every hour, and animals sacrificed 18 h after the oral administration of Garcinia cambogia extract. We examined changes in the serum concentration of Garcinia cambogia by HPLC analysis. Two hours following an oral administration of Garcinia cambogia extract (2,800 mg/kg b.w.), serum Garcinia cambogia levels reached their maximum, but gradually decreased until 10 hours when it was no longer detectable. In contrast, serum Garcinia cambogia levels under G3 administration were maintained above a certain level after 18 h. To determine whether this level of Garcinia cambogia could affect blood oxidative levels, we measured serum lipid peroxidation by TBARS levels. TBARS levels from G3 treatment were significantly lower than G1 and G2. To analyze other antioxidative activities, radical scavenging activities were measured by the DPPH and ABTS radical scavenging assays. There were no significant differences between the groups in DPPH radical scavenging activity. However, ABTS radical scavenging activity significantly increased with G3 treatment compared with G1 and G2. In conclusion, our data show that three times administration of Garcinia cambogia every 6 h may helpful for maintaining serum Garcinia cambogia levels and antioxidative effects.

In this study, changes in performance of 2-back task, blood oxygen saturation and heart rate due to $40\%$ concentration oxygen supply were observed. Five male $(25.8\pm1.3)$ and five female $(23.0\pm1.0)$ college students were nked to perform 2-bark task during two types of oxygen (concentration $21\%,\;40\%$) administration. The experimental sequence consisted of Rest1(1 min.), 0-back Task (1 min.), 2-bark Task (2 min.), and Rest2 (4 min.) and the physiological signals such as blood oxygen saturation and heart rate were measured throughout the stages. The experimental result showed that the performance increased significantly at $40\%'s$ concentration of oxygen rather than $21\%'s$, which shows oxygen supply has positive influence on cognitive performance. When $40\%$ concentration oxygen is supplied, the oxygen saturation in the blood increased and heart rate was decreased significantly comparing to $21\%$. It is Suggested that $40\%$ oxygen can stimulate brain activation bY increasing actual blood oxygen concentration in the process of cognitive performance, and hyperoxia makes heart rate decrease.
