This study tried to suggest the applicapability of soy protein supplementation and treadmill running exercise for the replacement theraphy on negative effects to estrogen metabolism in menopause. This study was analyzed the effects of 8 week soy protein supplementation and treadmill running exercise on the changes of body composition, blood concentrations of glucose, insulin, triglycerides, C-reactive protein (CRP) and estradiol, estrogen receptor gene expression of liver in ovariectomized rats. Ovariectomized groups showed the increasing responses of body weight, body fat percentage, and blood concentration of triglycerides, but these groups showed the decreasing responses of blood estradiol level and estrogen receptor gene expression in liver. Ovariectomized groups showed the positive responses of blood concentrations of lipid markers, insulin, estradiol, and estrogen receptor gene expression of liver except bone mineral contents after 8 week soy protein supplementation and treadmill running exercise. I could find the positive effects of 8 week soy protein supplementation and treadmill running exercise on the estrogen and lipid metabolism in ovariectomized rats, but this study could not confirmed the detailed replacement program of exercise intensity, duration, and soy protein volume for estrogen metabolism in ovariectomized rats.

Objectives: Obesity is a globally prevalent public health issue. Hence, there is a need for the development of safer and more effective anti-obesity drugs. Lythrum salicaria, a traditional medicinal herb used for centuries, has been reported to improve lipid metabolism and fat accumulation. It also has a low toxicity profile. Therefore, its potential as a functional ingredient in health functional foods needs to be evaluated. Methods: In this randomized, double-blind, placebo-controlled clinical trial, 90 participants will be randomly assigned to either the experimental or control group. Each subject will orally receive L. salicaria extract (1,350 mg/day) (500 mg L. salicaria+850 mg lactose as vehicle) or lactose (1,350 mg/day) as a hard capsule formula for 84 days (12 weeks). The primary outcome will be body fat mass (kg), which will be assessed using dual-energy x-ray absorptiometry (DXA) (performed only at visits 2 and 4). Secondary outcomes include body mass index, body weight, waist-to-hip ratio, body fat percentage (%) measured using DXA, lean body mass (kg) measured using DXA (assessed only at visits 2 and 4), lipids (total cholesterol, triglyceride, high-density lipoprotein cholesterol, and calculated low-density lipoprotein cholesterol), free fatty acid, high sensitivity C-reactive protein, adiponectin, and leptin. Conclusions: This protocol will be implemented after approval of Institutional Review Board of Pusan National University Korean Medicine Hospital (approval number: PNUKHIRB-2022-08-002) and registration with the Korean National Clinical Research Information Service (CRIS) (CRIS-KCT0008060). The results of this trial will provide potential of L. salicaria as a new anti-obesity functional food with fat-reducing effects and low toxicity.

In this study, the anti-obesity effect of Geranium wilfordii Maxim. extract was studied using 3T3-L1 cells. Geranium wilfordii Maxim. was extracted with water (NG-GT-T1L), 10% ethanol (NG-GT-T2L), 30% ethanol (NG-GT-T3L), 50% ethanol (NG-GT-T4L), 70% ethanol (NG-GT-T5L), and the effects on cell viability, lipid accumulation, triglyceride content, and protein expression in 3T3-L1 cells were confirmed. It was confirmed that NG-GT-T3L extract was superior to other extract conditions in reducing lipid accumulation and triglyceride content in the concentration range that did not show cytotoxicity. In addition, it was confirmed to suppress adipogenesis and lipogenesis by reducing the expression of peroxisome proliferator-activated receptor-gamma (PPARγ) and CCAAT/enhancer binding protein-α(C/EBPα) proteins that regulate adipogenesis, decreasing the expression of fatty acid synthetase (FAS) and stearoyl CoA desaturase-1 (SCD-1) proteins that regulate lipogenesis, and increasing the expression of AMP-activated protein kinase (AMPK) protein. From these research results, Geranium wilfordii Maxim. NG-GT-T3L extract is believed to have anti-obesity reduction effects through suppressing lipid accumulation and triglyceride accumulation and regulating adipogenesis and lipogenesis-related proteins.

The purpose of this study was to investigate the effects of medical nutrition therapy(MNT) on plasma lipid levels of hyperlipidemic patients with apo E3 genotype according to Sasang Constitutions. From March to July, 2001, the 33 hyperlipidemic patients admitted to K University Medical Center were studied. The study subjects were classified according to their Sasang constitutions by QSCC II questionnaire which have been used at K University Oriental Medical Center. The anthropometric assessments, blood analysis, and apo E genetic typing were carried out. Nutrient intake was determined by food record method of food taken during two weekdays and one weekend. The MNT including the instruction for hypolipidemic and hypocholesterolemic diet (step l diet) was performed for 12 weeks. The results are as follow; (1) The mean age of hyperlipidemic patients was $49.91{\pm}8.48$ years. (2) The distributions of Sasang Constitution were 60.6% of Tae-eum, 21.2% of So-yang, and 18.2% of So-eum. The distributions of apo E genotype were 6.5% of apo E2/3, 78.8% of apo E 3/3, and 15.2% of apo E 3/4. (3) The nutrient consumption of the apo E3 subjects before the MNT showed lower calorie, iron, calcium, and vitamin B2 intakes than the RDAs for each nutrients with no significant differences among the constitutions. After 12-week of MNT, only the fat consumption was decreased in the Tae-eum group. The MNT did not change the pattern of food intake. (4) The plasma level of triglyceride, total cholesterol, and LDL-C were not changed after MNT in the three constitutional groups. The level of HDL-C was significantly increased significantly in Tae-eum and So-yang group and the level of homocystein was lowered in Tae-eum group after MNT. It could be concluded that the 12-weeks MNT with hypolipidemic and hypocholesterolemic diet did not change the level of total cholesterol, triglyceride, and LDL-C effectively regardless of Sasang constitutions even though the subjects' dietary intake was improved by MNT.

The oxidative stability of lipids from eel (Anguilla japonica) fed diets containing different concentrations of conjugated linoleic acid (CLA) was studied. Eels, 3 weeks of age, with an average weight of 160 g, were randomly divided into 5 groups (5 fishes/group) by body weight, and assigned to one of the five CLA-supplemented diets at the following concentrations: 0, 0.5, 1.0, 2.5, and $5.0\%$ CLA. After 8 weeks of feeding, eels were sacrificed and the total lipid contents were extracted. The lipids from each treatment groups were stored at $37^{\circ}C$ for 5 weeks. Changes in the fatty acid profile, lipid class, weight gained, peroxide value (POV) and carbonyl value (COV) of the lipid from each treatment groups were analyzed weekly. The composition of CLA in the lipids of eels fed with 0.5, 1.0, 2.5, and $5.0\%$ CLA-supplemented diets were 0.5, 1.7, 3.3, and $6.2\%$, respectively After 4 weeks of storage, the proportion of polyunsaturated fatty acids (PUFAs) in the lipid of eels fed diets containing 1.0 and $2.5\%$ CLA were 15.3 and $14.8\%$, respectively. Whereas, lipid extracted from eels fed with 0.5 and $5.0\%$ CLA-supplemented diets contain 11.8 and $7.4\%$ PUFAs, respectively. Lipid from the control sample contained $9.0\%$ PUFAs. POV and COV were found to be the lowest in the lipids samples from 1.0 and $2.5\%$ CLA diets. These results indicate that lipids from diets containing 1.0 or $2.5\%$ CLA were more stable against oxidative rancidity relative to other concentrations, suggesting that these are the appropriate CLA concentrations for the production of stable eel lipids.

The purpose of this study was to investigate the effects of 12-week elastic band exercise on body composition, blood lipids and AMPK in 24 elderly female volunteers aged 65-75 years, and they were divided into the combined exercise group(n=12) and the control group(n=12). The elastic band exercise method was to do exercise 3 times a week for 60 minutes per session, 1-4 weeks for low intensity of OMNI-RES 3-4, 5-8 weeks for medium intensity of OMNI-RES 5-6, 9-12 weeks for OMNI-RES 7-8 of high intensity. In order to compare the differences in the groups before and after the elastic band exercise, two-way repeated measures ANOVA was used to verify the interaction between group and time. The difference in the groups of the measured data was paired t-test, the difference between the groups was paired independent t-test, and analysis of covariance ANCOVA was performed to minimize the inter-group error. The statistical significance level of each item was set to .05. As a result, body fat percentage of exercise group significantly decreased (p<.05), and skeletal muscle volume was significantly increased (p<.01). TC, TG and LDL-C were not significantly different between the exercise and control groups, and HDL-C was significantly decreased in the control group (p<.05). AMPK was significantly decreased in the exercise group (p<.001), but there was no significant difference in the control group. According to the covariance analysis to minimize the error of difference between the pre-exercise groups (p<.05), there was significant difference in AMPK of groups after exercise. These results suggest that the 12-week elastic band exercise has a positive effect on the body composition and AMPK of the elderly women.

This experiment was conducted to study effects of different sources of protein, and of the different combination ratios of the two protein supplemented or unsupplemented with methionine on the growth and body metabolism of the growing male rats. Casein and isolated soyprotein (ISP) were combined at different ratios of 100:0, 80:20, 50:50, 20:80 and 0:100 to supply the constant levels of dietary energy and protein of 3,600kcal/kg and 20%, respectively. Each combination was supplemented with either 0 or 0.3% methionine. Results obtained in these experiments were summarized as follows: The body weight and weight gain in the ISP diet were the lowest, but were increased with the increase of ratios of casein to ISP. The body weight gain in the ISP diet supplemented with methionine was similar to that in the combination diets of casein and ISP. The combination diets of casein and ISP supplemented with methionine had the higher weight gain than the casein diet. The food intake in the casein diet was the highest, and was increased with the increase of ratios of casein to ISP, and was lowered with methionine supplementation. The food intake in the ISP diet was the lowest and was not increased with methionine supplementation to the ISP diet. The food efficiency ratio of the combination diets of casein and ISP was improved compared to those of either the casein or the ISP diets. The food efficiency ratio was improved in the diet of either casein of ISP supplemented with methionine, but was not improved in the combination diets of casein and ISP with methionine supplementation. The gross energy intake had direct relation with the food intake of rats and the relation was increased either in the casein diet of with the increase of the ratios of casein to ISP. The energy efficiency and protein efficiency ratios were improved in the diet of either casein of ISP by the supplementation of methionine, and the effect of methionine supplementation of the energy efficiency and protein efficiency atio was increased with the increase of the ratios of ISP to casein. The nitrogen intake and urinary nitrogen excretion of the casein diet were the highest and those of the ISP diet were the lowest. They were increased with the increase of ratios of casein to ISP. The nitrogen balance and retention were not significantly among the treatments. The gross energy intake and fecal and urinary energy were the highest in the casein diet but the digestible and metabolizable energy and the digestibility and metabolizability of energy were not significantly different among the treatments. The body fat content of rats was increased by supplementation of methionine but the body protein content was decreased (r=-0.65, p<0.01). The body fat content of rats was negatively correlated with body moisture content (r=-0.83, p<0.01). The liver weight was highly correlated with the carcass weight (r=0.79, p<0.01), and was increased by the methionine supplementation and by the increase of the ratios of casein to ISP.

Objectives: The purpose of this study was to evaluate the anti-climacterium effects of Jibaekjihwang-tang (JBJHT), especially on estrogenic, anti-obesity, hypolipidemic, hepatoprotective against fatty liver and anti-osteoporotic effects by Ovariectomy (OVX) mice. Methods: In order to evaluate anti-climacterium effects of JBJHT, we used bilateral OVX female ddY mice. In this study, six groups were used; sham control, OVX control, estradiol, JBJHT 500, 250 and 125 mg/kg treated groups. Since 28 days after OVX surgery, JBJHT extracts were orally treated, and $17{\beta}$-estradiol $0.03{\mu}g/head$ were subcutaneously injected for 84 days, once a day. And then, we observed anti-climacterium effects classified into five categories; estrogenic, anti-obesity, hypolipidemic, hepatoprotective against fatty liver and anti-osteoporotic effects. The results were compared with $17{\beta}$-estradiol $0.03{\mu}g/head$/day subcutaneous treated OVX mice. Results: OVX control mice showed noticeable hypertrophic changes of adipocytes in abdominal fat pads, fatty liver, uterine atrophic changes, decreases of bone strength were also observed in OVX control. However, these estrogen-deficient climacterium symptoms were significantly and dose-dependently inhibited by JBJHT 500, 250 and 125 mg/kg treatment. Moreover, JBJHT 500 mg/kg showed comparable inhibitory effects as compared to those of estradiol $0.03{\mu}g/head$/day subcutaneous treatment. Conclusions: The results suggest that oral administration of JBJHT 500, 250 and 125 mg/kg has clear dose-dependent anti-climacterium effects in OVX mice.

Purpose : The aim of this study was to predict radiation dose at 1 meter with BMI(body mass index) in thyroid cancer patients treated with radio-iodine and provide the efficient guideline in the management of patients. Methods : 140 patients from thyroidectomy for thyroid cancer were enrolled. All subjects under went 150 mCi radio-iodine therapy and performed whole body scan 1 week later. BMI(weight divided by square of height) was calculated to evaluate the amount of fatty tissue indirectly. The radiation dose at 1 meter was measured initially and on 2nd days. the relation of values with BMI were analyzed statically. As for the method of statistical analysis, using Med calc Version 9,2,2,0 Program. Results : (1) The initial effective dose was inversely correlated with the BMI. Significance level was 0.0004. (2) We obtained the following formula from the data of initial effective dose and BMI: Y = -30.91X + 350.4(${\mu}Sv/h$)(Y: initial radiation dose, x: Group). (3) After 21.55 hours, than radiation dose was less than those recommended by ICRP or NRC in 53% of the population. Conclusion : Using BMI, the initial radiation dose and 2nd days dose can be predicted in thyroid cancer patients before radio-iodine therapy. It may be used for predicting the time of discharge and control the isolation room. We were able to predict the radiation exposure after discharge using this calculated value.
