Objectives The object of this study was to evaluate the effect of Yikgeebohyul-tang aqueous extracts (YKBHT) on the propylthiouracil (PTU)-induced rat hypothyroidism. Methods The rats were divided into 6 groups : intact vehicle control, PTU control, LT4, YKBHT 500, 250 and 125 mg/kg treated groups. Hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28 days. YKBHT aqueous extracts were administered once a day as an oral dose of 500, 250 and 125 mg/kg for 42 days. The changes were observed : weight of body, thyroid gland, liver, testis, epididymis and prostate, serum thyroid hormone levels, serum male sex hormone levels, serum lipid profiles, liver and testis antioxidant system. These results were compared with LT4 0.5 mg/kg intraperitoneally treated rats. Results These PTU induced hypothyroidism and related hepatic and male reproductive organ damages were favorably and dose-dependently inhibited by treatment of YKBHT 500, 250 and 125 mg/kg, and YKBHT also effectively regulated the PTU-induced abnormal antioxidant defense factor changes in the both liver and testis. Although, LT4 also inhibited PTU-induced hypothyroidism and relative liver damages. But it deteriorated the hypothyroidism related testis, epididymis and prostate damages through testicular oxidative damages. Conclusions : The result of this study suggests that YKBHT has favorable effects on the hypothyroidism and related liver and reproductive organ damages with augmentation of antioxidant defense factor in the testis and liver. YKBHT 500, 250 and 125 mg/kg dose-dependently inhibited PTU-induced hypothyroidism and related liver and male reproductive organ damages in rats.

There are no published data on Gyeongokgo (GOK) safety or efficacy despite being commonly use. The Gyeongokgo (GOK) is commonly used in traditional Korean medicine to promote a health qi and blood, but their objective data was not sufficient in clinical field. To investigate the safety and efficacy of GOK with hematologic and serologic testing and the change of the quality of life in healthy individuals. Randomized, subject-assessor-blind, placebo-controlled, single-center pilot study Participants and Interventions 29 healthy volunteer subjects were randomly placed into the GOK group (n = 20) or placebo control group (n = 9) and instructed to take one treatment packet (GOK or placebo) twice daily for 4 weeks. Subjects were assessed using the Fatigue Severity Scale (FSS) and Short Form 36 Health Survey (SF-36) and underwent hematologic and serologic tests and body composition analysis. The FSS total score (p = 0.093) and SF-36 general health index (p = 0.002) were improved following treatment in the GOK group. Post-treatment thyroid-stimulating hormone levels were increased in the GOK group compared with pre-treatment levels (p = 0.0042). C-reactive protein levels decreased (p = 0.0256) in the GOK group compared with that the placebo group. In time-series tests, GOK did not affect post-prandial serum triglycerides, glucose, insulin, or C-peptide levels. Notably, elevations in serum fasting triglycerides at 2- (p = 0.0333) and 4-hours (p = 0.0414) post-prandial were lower than those in the placebo group. GOK reduced fatigue levels and did not significantly affect laboratory test results performed to measure safety, serum glucose, and lipid profiles. Post-meal triglyceride levels were effectively reduced with treatment.

This study was performed to determine the effect of Takju(Korean turbid rice wine) lees on the serum glucose level in streptozotocin-induced diabetic rats. 24 Sprague-Dawley male rats were divided into three groups: normal control(NC), diabetic control(DC) and diabetic rats(DS) were fed on experimental diet and water ad libitum for 4 weeks. DS diet was containing 20% Takju lees. Body weight gain and food Efficiency Ratio(FER) were significantly lower in DC and DS than NC. DS tended to have higher weight, weight gain and FEF than DC nevertheless food intake. Therefore Takju lees could possibly complement casein as a protein source. Gastrointestianl transit time in DS significantly decreased than NC while not significantly than DC. Serum lipid profiles and AST. ALT and amylase were not significantly different between diabetic DC and DS. Blood glucose was measured at fasting state and 30, 60, 90 and 120 minute by oral glucose tolerance test, DS tended to lower the mean(${\pm}$ SE) incremental blood glucose concentrations than DC and was significantly low at 120 min. But incremental AUG(area under the curve) of postprandial glucose response was not significantly different. In conclusion, in spite of high contents of carbohydrate Takju lees perhaps have a benefit effect on the diabetes.

This study examined the protective effects of an ethanol extract of Youngia denticulata leaf (YDL) and Youngia denticulata root (YDR), and Youngia sonchifolia leaf (YSL) and Youngia sonchifolia root (YSR) on acute ethanol-intoxicated rat. The rats were pretreated with an ethanol extract of YDL, YDR, YSL and YSR for 4 weeks before being exposed to ethanol (5 g ethanol, po/kg BW). The biochemical indices (hepatic alcohol metabolic enzymes and serum ALT activities, and hepatic and serum lipid profiles) were examined to evaluate the protective effects. The hepatic ADH activities in all experimental groups were not changed significantly by acute ethanol after a pretreatment with the YS and YD ethanol extracts. In contrast, the ALDH activity in EC (ethanol control) was higher than that of NC (normal control); these activities in the YDL and YSL groups were significantly higher than that of the EC group. On the other hand, acute ethanol exposure resulted in a significant increase in the serum TG, total cholesterol, LDL-cholesterol, hepatic TG, total lipid and cholesterol levels, and serum ALT activity, and a decrease in the serum HDL-cholesterol. A pretreatment with the YS and YD ethanol extracts dramatically attenuated these adverse effects. In particular, the YDL pretreatment markedly suppressed the ethanol-induced increase in the serum and hepatic TG and total cholesterol levels. Furthermore, serum ethanol was decreased by a pretreatment with YSL, YSR, YDL, or YDR. Overall, YD and YS ethanol extracts attenuate acute ethanol-induced hyperlipidemia and fatty liver significantly. Nevertheless, further study will be needed.

This study investigated anti-obesity and antioxidant effects of dietary non-fermented soybean crud residue (SCR) and fermented SCR by Monascus pilosus (FSCR) in high-fat induced-obese mice. SCR and FSCR were supplemented with high-fat diet at 2% (wt/wt) dose for 8 weeks. Both SCR and FSCR significantly lowered body weight, epididymal fat weight and weight gain rate compared to high-fat diet control (HC) group and FSCR group showed lowest weight gain rate. In addition, it was observed that serum and hepatic lipid profiles including triglyceride, total cholesterol, LDL-cholesterol and HDL-cholesterol were significantly improved by supplementing SCR or FSCR. Furthermore, SCR and FSCR administration showed increase of glutathione content and decrease of hepatic lipid peroxide content, serum aminotransferase activity, and hepatic xanthine oxidase activity. On the other hand, activities of reactive oxygen species scavenging enzyme such as superoxide dismutase, glutathione S-transferase and glutathione peroxidase in two test groups were higher than those of HC. Lastly, in comparison with SCR, FSCR was more effective in restoring obesity-related biomarkers to normal level in high-diet induced obese mice. In conclusion, the present study indicates that FSCR could have not only anti-obese effects such as inhibition of abdominal fat accumulation, but also protective effects of cardiovascular disease such as atherosclerosis by decreasing serum and hepatic lipid contents. Furthermore, these results suggest that experimental diets in this study could alleviate hepatic damage caused by overproduction of reactive oxygen spices (ROS) due to obesity via inhibition of ROS generating activities and induction of ROS scavenging activities.

The purpose of this study was to investigate the relation among mineral intakes, blood pressure, and blood lipids for health management of Korean adults over 20 years old. Subjects were recruited from the district where they lived, which included rural (Yoju, n = 137) , coastal (Taean, n = 100) , and urban district (Suwon, n : 117) . hnthropornekical measurement, blood pressure measurement, dietary intake assessment using 24-hour recall method, and blood collection and analysis of blood lipids were conducted. The average age, height, weight, and BMI were 54.1 years, 168.5 cm, 67.3 kg, and 24.5 kg/$m^{2}$ for men and 53.9 years,153.8 cm,59.2 kg, and 25.0 kg/$m^{2}$ for women, respectively. The mean daily intakes of total food and energy were 1219.1 g and 1740.9 kcal for men and 1071.3 g and 1432.6 kcal for women. The mineral intakes of men and women were 448.5 mg and 400.4 mg for calcium,955.3 mg and 803.7 mg for phosphorus, 13.3 mg and 11.1 mg for iron, 4302.8 mg and 3393.3 mg for sodium,2588.0 mg and 2264.9 mg for potassium, and 8.9 mg and 7.3 mg for zinc. The daily intakes of energy, calcium, zinc, vitamin $B_{2}$, and vitamin I were $76.1\%$, $60.1\%$, $73.1\%$, $68.6\%$, and $80.4\%$ of RDAs, respectively. The intakes of energy, calcium, zinc, vitamin $B_{2}$ and I were not meet Korean RDAs. Especially, calcium, zinc, and vitamin $B_{2}$ were less than $75\%$ of RDAs. Blood pressure of the subjects was 128.3/75.5 mmHg for men and 124.1/73.7 mmHg for women. Serum lipids of men and women were 180.2 mg/dL and 184.9 mg/dL for total cholesterol, 160.8 mg/dL and 137.6 mg/dL for triglyceride,41.5 mg/dL and 44.7 mg/dL for HDL-cholesterol,106.6 mg/dL and 112.7 mg/dL for LDL-cholesterol, and 3.5 and 3.3 for atherogenic index. While serum triglyceride and AI of men was significantly higher, HDL-cholesterol was lower than those of women. In the relation among mineral intakes, blood pressure, and serum lipids, we found a significantly negative correlation of intakes of calcium, calcium/phosphorus, calcium density with systolic blood pressure. There were significantly negative correlation between intake of calcium/phosphorus and serum cholesterol, calcium density and serum cholesterol, sodium intake and serum HDL-cholesterol. Based on these results, we concluded that high intakes of calcium, calcium/phosphorus and low sodium intake were associated with favorable blood pressure and serum lipid profiles in adult men and women.

The effects of pan-fired (PM) and fermented (FM) Cudrania tricupidata tea leaves on $\alpha$-glucosidase inhibitory activity, oral glucose tolerance, blood glucose levels and serum lipids profiles in streptozotocin (STZ)-induced hyperglycemic rats were investigated. The $\alpha$-glucosidase inhibitory activity of FM ethanol extracts (20 mg/mL) was higher (92.5%) than that of raw dried leaves (RM) (69.1%) and PM (54.6%). In addition, the results of a glucose tolerance test revealed that the glucose levels of hyperglycemic rats that were fed PM and FM ethanol extracts and then orally administered glucose began to decrease after 60 minutes, but recovered after 120 minutes. However, the blood glucose levels in the hyperglycemic control group did not begin to decrease for 360 minutes. Additionally, the results of animal experiments that were conducted over five weeks to compare the dietary effects of PM and FM following hyperglycemic induction to the effects on the hyperglycemic control group (DM) were as follows: The body weight gain and FER of the treated rats were $12.9{\sim}16.9%$ higher than those of the DM group, whereas the amounts of feed and water intake by the treated rats were $6.8{\sim}10.1%$ lower. Additionally, the levels of blood glucose and serum fructosamine decreased by $27.3{\sim}39.8%$ and $6.7{\sim}20.0%$, respectively, in the treated rats. Moreover, the serum triglyceride, total cholesterol and LDL-cholesterol concentrations in the treated rats were $24.9{\sim}27.1%$, $15.9{\sim}17.4%$ and $33.8{\sim}38.4%$ lower, respectively. Finally, the HDL-cholesterol contents were $20.5{\sim}24.8%$ higher in the treated rats than in the control group. The above results suggest that PM and FM exerts an anti-hyperglycemic effect that occurs due to the inhibition of $\alpha$-glucosidase activity as well as via prevention and/or inhibition of changes in the serum lipid profile. In addition, the results of this study revealed that the synthetic anti-hyperglycemic effect of FM was greater than that of PM. However, further detailed studies are needed to confirm these results.

This study examined how the participation rates contribute to subjects' outcomes after a nutrition education (once/week) and exercise (3 times/week) intervention program for 12 weeks in 44 obese female subjects. The subjects were divided into two groups: high-participator (HP) or low-participator (LP) groups according to their participation levels based on the median visit value (30 visits out of a total of 48 visits). Daily nutrient intakes assessed by a 24-hour recall, body composition, blood lipid profiles and physical fitness were measured at baseline and after 12 weeks. After the intervention, weight, BMI, percent body fat, and the waist-hip ratio were significantly decreased in the HP group. In addition, the HP group had a greater rates of changes in weight (HP group: -6.6% and LP group: -3.1%, p < 0.01), BMI (-7.0% and -3.2%, p < 0.01), percent body fat (-7.8% and -4.2%, p < 0.05), and waist-hip ratio (-3.1% and -0.4%, p < 0.01) compared to the LP group. Energy-adjusted protein, fiber, potassium, vitamin $B_1$, vitamin $B_6$, and vitamin C were significantly increased in the HP group. The HP group showed a significant increase in HDLcholesterol and a decrease in blood pressure, total cholesterol, LDL-cholesterol, triglycerides, and atherogenic index (AI). While the muscle endurance, muscle strength, power, agility and flexibility were significantly increased in the HP group, agility and balance were improved in the LP group. In addition, dietary behavior score was significantly increased and stress score decreased in the HP group compared to the LP group. High participation rates were correlated with the improvement of the nutrient density (protein, fiber, potassium, Vitamin $B_1$, Vitamin $B_2$, Vitamin $B_6$ and folate), anthropometric parameters (body weight, BMI and percent body fat), serum lipid profiles (HDL-cholesterol, Triglyceride, and AI) and physical fitness (muscle endurance) adjusted for age, menopausal status, alcohol drinking, nutritional supplement use and baseline BMI. Our results suggest that high participation in nutrition education and exercise program was effective not only for weight reduction but also for the improvement of physical fitness in obese women.

Purpose : Every year, there is a remarkable increase in the prevalence of children with excess body fat. The aim of this study is to find a useful screening method in assessing adolescent, obesity and to specify the predictable risk factors that are related to adult cardiovascular disease according to BMI and obesity index. Methods : From July to November in 2001, a total of 2,814(male : female=2,011 : 803) mid to high school students who were in the obesity range according to obesity index(>20%) were evaluated according to height, weight, body mass index(BMI), obesity index, and serum lipid levels. Results : Among the obese students over 20% by obesity index, 86.6% were over the range of 95 percentile by BMI. Among students defined as obese by BMI, 21.0% of males and 21.4% of females students had hypercholesterolemia; by obesity index, the ratio was 20.7% male and 19.0% female. The frequency of hypertriglyceremia in male students was 15.0% in group I(overweight group, 85P97p); in female students 11.8%, 20.7% and 28.2% respectively. Conclusion : In this study, using BMI alone to test the serum lipid level in adolescent obesity had a limit of 10.0-17.0% omission. Therefore using obesity index as a screening method to find the adult cardiovascular disease would rather reduce the omission rate. The risk factor of cardiovascular disease according to BMI was the increasing level of triglyceride in both male and female students. We think that using the obesity index has more rationale rather than BMI in assessing lipid profiles.

This study was performed to investigate the effect of ethanol extract of Pimpinella brachycarpa (PB) on serum and liver lipid metabolism in rats. Male Sprague Dawley rats were administered 1% cholesterol and 0.25% sodium cholate to induce hypercholesterolemia. PB ethanol extract (200 mg/kg/day or 400 mg/kg/day) was also administered orally to rats with high cholesterol diet for 6 weeks. We divided 40 rats into five groups; normal diet group (NC), high cholesterol diet group (HC), normal diet and PB ethanol extract (200 mg/kg) administered group (NC-PB), high cholesterol diet and PB ethanol extract (200 mg/kg) administered group (HC-PBL), and high cholesterol diet and PB ethanol extract (400 mg/kg) administered group (HC-PBH). The growth rate and liver weight of the high cholesterol diet group was higher than those of the normal diet group, whereas those of the groups administered PB ethanol extract were gradually decreased. There was a signigicant increase in the activities of serum alanine aminotransferase (ALT), asparate aminotransferase (AST) and alkaline phosphatase (ALP) in the high cholesterol diet group. The administration of PB ethanol extract decreased serum ALT, AST and ALP activities in a dose-dependent manners. The high cholesterol diet group showed increased serum triglyceride, total cholesterol, free cholesterol and LDL-cholesterol levels, and decreased atherogenic index, HDL-cholesterol and phospholipid levels as compared with the normal diet group. PB ethanol extract administrated groups showed increased HDL-C/T-C, HDL-cholesterol and phospholipid levels, and decreased serum triglyceride, total cholesterol, free cholesterol, and LDL-cholesterol levels as compared with the high cholesterol diet group. There were no differences in the concentrations of serum triglyceride, phopholipid, LDL-cholesterol, HDL-cholesterol and free cholesterol between normal diet groups. The hepatic concentrations of total cholesterol and triglyceride were also lower in PB ethanol extract administrated groups than in the high cholesterol diet group. These results suggest that ethanol extract of PB exerts hypocholesterolemic effect by reducing serum and liver cholesterol contents.
