The purpose of this research was to investigate the effects of dried orange peel compound intaking and exercise training on the physique, body fat, and concentration bloodlipid in obese women. Ninety-seven volunteers(mean age 21.47 ${\pm}$ 1.47 yrs), all over 30% of body fat, agreed to Participate and were placed in 4 groups: dried orange peel compound intaking and exercise group(n=25), only exercise group(n=25), only dried orange peel compound intaking group(n=24), and control group(n=20). The subjects who joined this project were asked to take dried orange peel compound(2 times/day, 30 ml/time) or participate in exercise program(3 times/week, 70 min/day), depending on particular group for 12 weeks. They were tested on their height, weight, circumference of chest, abdomen, hip, and thigh, body fat%, total-cholesterol(TC), HDL-C, LDL-c, and triglyceride(TG) at the beginning and the end of the 12-weeks program. For data analysis, paired t-tests and ANCOVAs were used. The intaking of dried orange peel compound was influenced on weight, circumference of chest, abdomen, hip, and thigh, body fat%, HDL-C, LDL-C, and TG. The exercise participation had almost same effects on those dependent variables. Furthermore, the dried orange peel compound intaking along with exercise training was the most effective on those dependent variables among them. Therefore, these results indicate that dried orange peel compound intaking, like exercise, may be useful for controling weight, body fat, HDL-C, LDL-C, and TG.

In postmenopausal women, estrogen deficiency can be associated with metabolic diseases, such as obesity, diabetes, and cardiovascular diseases. The purpose of this study was to investigate factors related to lipid, glucose and antioxidnat metabolism. Sprague-Dawley female rats were subjected to either bilateral ovariectomy or sham operation and randomly divided into 3 dietary groups, (n=8) sham-operated fed with normal diet (SHAM), ovariectomized fed with normal diet (OVX), and ovariectomized fed with normal diet supplemented with Eucommia ulmoides extract (OVX-EU). The OVX-EU group showed significantly lower body weight, triacylglycerol, and total cholesterol than that showed by the OVX group. In addition, the OVX-EU group showed improved lipogenesis, glucose-regulating enzyme activities, adipokine and antioxidant enzyme activities. These findings demonstrate that extracts from E. ulmoides extract can be used as a functional food.

This study was to investigate the effect of betaine on the hypoglycemia and hepatoprotection of streptozotocin(STZ)-induced diabetic rats. Male Sprague-Dawley rats weighing around 280 g were randomly assigned to the three experimental groups: a healthy normal group and two groups with STZ-induced diabetes and fed either control diet or betaine diet. Betaine given to the STZ-diabetic rats had significant effect in lowering the serum glucose concentrations compared to the STZ-diabetic rats. The alanine aminotransferase (AST) and aspartate aminotransferase (ALT) activities and triglyceride contents in serum were dramatically higher in the STZ-diabetic rats, but these increases in relation to diabetes also decreased in the STZ-diabetic rats fed betaine. However, the total-cholesterol concentration in the STZ-diabetic rats was even increased by betaine. The morphology of the pancreatic islets in the normal rats showed a typical round form, but most of the islets in the STZ-diabetic rats showed severe morphological alterations by being markedly destroyed. However, the islet morphology of STZ-diabetic rats given betaine mostly maintained a normal rounded appearance. The present study strongly suggests that the administration of betaine showed a moderate hypoglycemic effect by protecting the pancreatic beta-cells by morphological examination from STZ-induced destruction.

This study was carried out to investigate the feeding effect of wild grape wine by-products on pork qualities. The chemical composition, volatile basic nitrogen, thiobarbituric acid reactive substances and pH were not significantly different between control and wild grape pork, but the cholesterol and roast loss of wild grape polk. were lower than those of the control, and 1l1e salt soluble protein extractability of the control was lower than that of the wild grape pork. The Hunter's $a^{\ast}$ and $b^{\ast}$ value of wild grape polk. meat were higher than the control, the $a^{\ast}$ value of wild grape polk. meat was higher than the control, but the $L^{\ast}$ value of meat and fat were not significantly different between control and wild grape pork. The cohesiveness, gumminess and chewiness of control(respectively $66.2\%$ 428kg and 189g) were higher than wild grape polk. (respectively $61.4\%$ 357 kg and 154 g). The total amino acid composition of polk. were not significantly different between control and wild grape wine, The glutamic acid, leucine, arginine and aspartic acid were major amino acids in control and wild grape pork. The arachidonic acid $(C_{20:4})$, EPA $(C_{20:5})$ and DHA $(C_{22:6})$ of wild grape polk. were higher than those of the control. The taste (p<0.001), aroma (p<0.05), flavor (p<0.001), juiciness (p<0.01) and palatability (p<0.01) of wild grape polk. were higher than those of the control, but the texture between control and wild grape polk. were not significantly different.

As the tertiary industry is being developed, many problems are introduced in an industrial area in Korea. This study aims to investigate the residents' health conditions, such as the prevalence of metabolic syndrome and fatty liver diagnosed by ultrasonography, comparing the urban with the industrial areas. The subjects were 378 adults in the urban area and 376 adults in the industrial area. Subject variables accounted for were gender, age, drinking habits, smoking habits, physical activities, waist circumferences and BMI. In blood tests, fasting blood glucose, triglyceride, HDL, blood pressures, total cholesterol, AST, ALT and GGT were examined. Also, the presence and absence of fatty liver, diagnosed using ultrasonography, was investigated. As a result, the prevalence of metabolic syndrome were 43.7% in the urban area and 51.6% in the industrial area, hence it was significantly higher in the industrial area than in the urban area. Fasting blood glucose, triglyceride and waist circumference in the distribution of the individual components were 47.4, 53.7, and 16.1% in the urban area and 54.5, 61.5, and 22.9% in the industrial area respectively, so it was substantially higher in the industrial area than in the urban area. On the other hand, HDL, diastolic blood pressure, and fatty liver were 25.7, 43.4, and 44.7% in the urban area and 21.3, 19.9, and 36.7% in the industrial area respectively and thus it was much higher in the urban area than in the industrial area. In conclusion, this study shows that there were significant differences between the residents' health condition, comparing the urban area to the industrial area. Therefore, the precaution and aggressive management of metabolic syndrome may be necessary, in accordance with the characteristics of the industrial zone.

This study investigated the functional effect by diets of Triticum aestivum sprout (TA) on the levels of blood glucose and lipid profiles in streptozotocin(STZ)-induced diabetic mice. Diabetes mellitus were induced by STZ intraperitoneal injection (50 mg/kg) into the male Balb/c mice. All mice fed AIN-93 diet for 3 weeks. Mice were divided to 4 groups: normal, diabetic control and two experimental groups (TA 5.0, diet with Triticum aestivum sprout 5.0% w/w; TA 2.5, diet with Triticum aestivum 2.5% w/w). The blood glucose level was decreased by TA intake in diabetic mice in the dose-dependant manner; 21.34% and 35.77% in TA 2.5 and TA 5.0 groups. The weight gain and feed efficiency ratio also were improved by TA intake compared with DM group. The weight gain was increased 1.28 and 1.09 folds in TA 5.0 and TA 2.5 groups, respectively. The weight of organs, including liver and kidney, was reduced but that of spleen and abdominal fat was increased by TA intake. Moreover, TA treatment increased the level of HDL but decreased the level of total cholesterol and triglycerides in the blood of diabetic mice. The blood of HbA1c also was significantly decreased without changing hematocrit by TA treatment compared with DM group. These results indicate the TA intake has the functional effects attenuating blood glucose and plasma lipid levels in insulin-dependent diabetes.

A total of 70 colonies were isolated from the Korean human milk samples on the BCP plate count agar. These LAB isolates were subcultured in 10% reconstituted skim milk, and two strain thereof were finally selected for their highest acid productions. These strains were identified as Enterococcusfaecium based on 16S rDNA sequencing data, named as Enterococcus faecium KHM-11. Sugar utilization of E. faecium KHM-11 was investigated by API 50CH kit, and 19 different sugars including D-arabinose, L-arabinose, galactose, D-glucose, D-fructose, and D-mannose were utilized. For fermentation profiles, a yogurt inoculated by E. faecium KHM-11 after 15 hour, reached at pH 4.09, titratable acidity at 1.10% and average viable counts $1.30{\times}10^9\;CFU/mL$. Effects of the administration of yogurt 0.5% of piglet diet to piglets were investigated for growth rate, analysis of blood and incidence of diarrhea. 24 heads of piglets were divided into two groups: the experimental and the control of 12 animals each. The average growth rate in the yogurt-fed group was higher for 21.67%, compared with control (p<0.05). There were no differences in the concentrations of blood glucose, cholesterol, albumin and globulin between the two treatments. Incidence of diarrhea was no in pigs fed yogurt as compare to control.

The aim of this study is to investigate the effect of Lespedeza maximowiczii var. tricolor Nakai (LMTN) on glucose metabolism. LMTN extract significantly enhanced the glucose uptake and lipid accumulation in 3T3-L1 adipocytes compared with control. Also, LMTN extract in 3T3-L1 adipocytes significantly increased the protein expression of peroxisome proliferator-activated receptor (PPAR)γ, insulin receptor substrate-1, and glucose transporter (GLUT)4. The regulatory effect on glucose uptake or insulin signal transduction of LMTM extract was lower than troglitazone or pinitol such as the positive control, but increased PPARγ activation. Additionally, LMTM extract has an insulin-mimetic effect. In db/db mice, LMTN extract (250 mg/kg BW) significantly reduced water and food intake, blood glucose, and level of plasma triglyceride and total cholesterol. Furthermore, the expression of PPARã and GLUT4 mRNA in adipose or muscle tissue effectively was increased by oral treatment of LMTN extract. Thus, our results suggest that LMTN extract improves the glucose metabolism through PPARγ and insulin-mimetic effect in 3T3-L1 adipocytes and db/db mice.

Lovastatin, one of the potent cholesterol-lowering agents, is an inactive lactone prodrug which is metabolized to its active open acid, lovastatin acid (LVA). Bioequivalence study of two lovastatin preparations, the test drug ($Mevacor^{\circledR}$: Chungwae Pharmaceutical Co., Ltd.) and the reference drug ($Lovaload^{\circledR}$: Chong Kun Dang Pharmaceutical Co., Ltd.), was conducted according to the guidelines of Korea Food and Drug Administration (KFDA). Fourteen healthy male volunteers, $23.9{\pm}3.9$ years old and $67.6{\pm}8.0$ kg of body weight in average, were divided randomly into two groups and administered the drug orally at the dose of 160 mg as lovastatin in a $2{\times}2$ crossover study. Plasma concentrations of lovastatin acid were analysed by HPLC method for 12 hr after administration. The extent of bioavailability was obtained from the plasma concentration-time profiles of total lovastatin acid after alkaline hydrolysis of the plasma samples. By alkaline hydrolysis, trace amounts of unmetabolized lovastatin were converted to lovastatin acid. The $AUC_{0-12hr}$ was calculated by the linear trapezoidal rule method. The $C_{max}$ and $T_{max}$ were compiled directly from the plasma drug concentration-time data. Student's t-test indicated no significant differences between the formulations in these parameters. Analysis of variance (ANOVA) revealed that there were no differences in AUC, $C_{max}$, and $T_{max}$ between the formulations. The apparent differences between the formulations were far less than 20% (e.g., 7.07, 5.77 and 1.18% for AUC, $C_{max}$, and $T_{max}$, respectively). Minimum detectable differences(%) between the formulations at ${\alpha}=0.05$ and $1-{\beta}=0.8$ were less than 20% (e.g., 17.2, 15.1, and 15.9% for AUC, Cmax, and Tmax, respectively). The 90% confidence intervals for these parameters were also within ${\pm}20%$ (e.g.. $-5.20{\sim}19.3$, $-5.00{\sim}16.5$, and $-10.2{\sim}12.5%$ for AUC, $C_{max}$, and $T_{max}$, respectively). These results satisfied the bioequivalence criteria of KFDA guidelines, indicating that the two formulations of lovastatin were bioequivalent.

This studies were to investigate the effects of low power wavelengths Helium-Neon Infra-Red(He-Ne IR)laser on the changes of the blood biochemical components in burn rats. The thirty Spraque-Dewely adult male rats were assigned to the 5 groups; the experimental groups(3), the burn control group(1) and the control group(1). There was made three degree burn by the 250mW IR on the back of each rats, from 3 days after being, burned, the experimental laser groups were irradiated low power wavelengths (292Hz, 1168Hz, 4672Hz) He-Ne IR laser for 5 minutes every day during the 7days. The results wee as follows: The activities of aspirate aminotransferase(AST), alanine aminotransferase(ALT), and lactate dehydrogenase(LDH), on treated with the wavelengths ((292Hz, 1168Hz, 4672Hz) laser groups during 5 min. for 7 days were significantly increased to the control group respectively, but those of total cholesterol(CHOL) and alkaline phosphatase(ALP) were significantly decreased to the a control group (p<0.05). there were significantly decreased on the activity of alanine aminotransferase and alkaline phosphatase on the all experimental groups to the burn control group and those of lactate dehydronase on treated with 292Hz and 4672Hz wavelength9 groups to the burn control group but, were significantly increased on those of urea nitrogen (292Hz and 1168Hz)(p<0.05). The activity of AST, LDH, on treated with 1168Hz wavelengths were significantly decreased of the 292Hz and 4672Hz wavelengths groups that of ALT on the treated with 1168Hz group was significantly increased to the 4672 Hz wavelength group but those of CHOL and LDH on the 1168Hz and 4672Hz wavelength groups were dignificatly decreased to the MHz wavelengths group. As above results, the changes of the activities of biochemical conponents in the serum levels on the healing process have meaningful effected of the role of low power wavelengths He-Ne IR laser.
