It was reported that the digestion ratio of chlorella was low because it had a low metabolic rate in body. Generally, the thickness of a cell membrane of it is $200-250\;{\AA}$, the weight of it is approximatly 13% of the total weight of a dry cell. And it is composed of protein, lipid, hemicellulose and ash etc. So, in order to elevate the digestion ratio of chlorella in body, we experimented the crude treatment methods of chlorella. The results obtained in this experiment are summarized as follows : 1. The digestion ratios calculated from ordinary N- balance method were 83.05% for 10% chl. (b) plus diastase group ; 81.25% for 10% chl. (b) plus amylase group, and 79.23% for 10% chl. (b), 58.55% for 10% chl. (a). 2. Biological values from this method were 80.25% for 10% chl. (b) plus diastase group, and 60% for 10% for chlorella(a).

Recently proteasome inhibitors have been emerged as potential anticancer agents. In a continuous study on exploring proteasome inhibitors from natural products, fruiting body of Hericium erinaceum was investigated. The MeOH extracts of the fruiting body of Hericium erinaceum was fractionated with several solvents and the fractions were evaluated on the activity to screen the proteasome inhibitors. The n-Hexane and CHCl3 frs. showed potent activity, of which chemical investigations led to ergosterol peroxide (1), hericenones C (2) and D (3). Their structures were determined by spectroscopic methods such as $^1H$-NMR, $^{13}C$-NMR, and FABMS spectra.

Objectives: This study was designed to investigate the anti-obesity, anti-diabetic and anti-inflammatory effects of Platycodi radix on obese type 2 diabetes mouse model. Methods: Obese type 2 diabetes mouse model was induced by Surwit's high fat, high sucrose diet for 8 weeks. Models were divided into 4 groups of normal diet (ND, n=10), high fat and high sucrose diet (HFD, n=10), high fat and high sucrose diet with Platycodi radix (PR, n=10), and high fat and high sucrose diet with Metformin (Met, n=10). Body weights were measured every week. After 7 weeks fasting, blood sugar and oral glucose tolerance tests were conducted. After 8 weeks blood samples were taken from mouse hearts and analyzed biochemically. Lipid profile, fructosamine, leptin and weight of epididymal fat pad and liver were measured. Adipose tissue macrophage percentage was analyzed by fluorescence-activated cell sorting (FACS). Results: Compared with the HFD group, body weight, glucose level, fructosamine, weight of epididymal fat pad and adipose tissue macrophage percentage decreased in the PR group. Conclusions: These results suggest that Platycodi Radix has anti-obesity, anti-diabetic, and anti-inflammatory effects on obese type 2 diabetes mouse model.

Objectives: The present study was carried out to investigate the effects of YJT on experimental hypothyroidism induced by sodium perchlorate and methimazolein in mice. Methods: 30 one-month-old C57BL6 mice were decided into 4 groups: 1) normal (n=6), 2) sodium perchlorate and methimazolein-induced hypothyroidism control (n=8), 3) hypothyroidism mice treated with low YJT (n=8), 4) hypothyroidism mice treated with high YJT (n=8). Sodium perchlorate and methimazolein were administered for 4 weeks, YJT (low and high) was administered for 2 weeks after sodium perchlorate and methimazolein were initiated for a total duration of 2 week. The changes were observed : weight of body, T3, T4, TSH, follicular cells in the thyroid tissues, LDL cholesterol, HDL cholesterol, triglyceride and free fatty acid, FBG, AST, ALT and so on. Results: YJT did not affect body weight gain. YJT restored free T4 level decreased by sodium perchlorate and methimazolein and prevented shrinking of follicles and proliferation of follicular cells in the thyroid tissues. In addition, YJT lowered total and LDL cholesterol levels elevated by sodium perchlorate and methimazolein respectively and ameliorated distribution of fat in liver tissues. In addition, the effect on fasting blood glucose (FBG), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were also investigated. Conclusions: These data suggest that YJT can be used to treat woman patients which are accompanied with hypothyroidism relatively safely.

Objectives: This study was conducted to compare dietary habits, weight control behaviors, eating disorder risk and depression among middle school girls who were at various stages of dieting. Methods: Subjects were 391 girls attending a middle school in Kyeonggido, Korea. All the information was gathered by self-administered questionnaires. Eating disorder risk and depression were assessed using EAT-26 and PHQ-9, respectively. Data were compared among 4 groups; no interest in a diet (N=112), had experienced dieting (N=86), on diet currently (N=71), and plan to diet (N=122). Results: A higher number of students currently on diet tended to be unsatisfied with their own weight (p < 0.01), overestimated their weight (p < 0.05), and weighed own body frequently (p < 0.001), compared to those with only experienced dieting in the past or those who plan to diet, despite similar weights and body mass index. The students who experienced dieting in the past or those who plan to diet appeared to have several undesirable as well as desirable dietary habits and their risk of eating disorder was significantly more prevalent compared to those without an interest in dieting (p < 0.01), although significantly less prevalent compared to those currently on a diet. Conclusions: We conclude that unnecessary dieting is common among middle school girls and providing proper education with regard to healthy weights is needed to enhance their physical as well as psychological wellbeing.

Objectives : Recently a lot of research is being done for find antidiabetic medicine which has no side effects. This study aimed to investigate the antidiabetic and antiobesity effects of Supungsunki-hwan partitioned prescriptions on obese type 2 diabetes mouse. Methods : Type 2 diabetes mellitus and obesity were induced by Surwit's high fat, high sucrose diet for 8 weeks. Mice were divided into 3 groups of ND (normal diet, n=10) HFD (high fat and high sucrose diet, n=10) and SPP (high fat and high sucrose diet with Supungsunki-hwan partitioned prescriptions, n=10) groups. Body weights were measured every week. After 7 weeks, fasting blood sugar and oral glucose tolerance tests were conducted. After 8 weeks, blood samples of all mice were taken from their heart and analyzed biochemically. At the same time, epididymal fat pad and liver weights were measured. Histological size of white adipocyte were measured as well. Results : Compared with a HFD group, body weight, fructosamine, epididymal fat pad weight and white adipocyte size decreased. High-density lipoprotein cholesterol levels increased in the SPP group. Conclusions : These results suggest that SPP has antidiabetic and antiobesity effects in high fat, high sucrose diet induced obese mice.

Objectives : This study examined search on how the obesity indices, that are largely used in clinics such as waist circumference(WC), body mass index(BMI) and waist-hip ratio(WHR), are related to the visceral fat that was measured from abdominal computed tomography(CT) and the ratio of visceral fat/subcutaneous fat. Then, two groups ware compared in order to find out which characteristics of ordinary adults relationship with the abdominal obesity. Two groups are divided as follows; ones who are obese based on the measurement of WC and the others who are obese based on the level of BMI. Methods : A group of 63 test subjects that were gathered in the oriental medical hospital of Kyung-Won university is divided into two groups; ones (n=51, general obesity; group A) who have $BMI{\geq}25$ and $WC{\geq}85$, and the others (n=12, abdominal obesity; group B) who have BMI<25 and $WC{\geq}85$. Then, each group's obesity indices, abdominal CT, lipid level, glucose, adiponectin, leptin and C-reactive protein(CRP) are compared. In addition, subjects are again divided into two to examine the characteristics; ones (n=14, visceral obesity; group C) with visceral obesity based on the ratio between visceral fat and subcutaneous fat measured through abdominal CT, and the others (n=38, non-visceral obesity; group D) who are obese but not viscerally obese. Results & Conclusions : As a measurement that applies abdominal visceral fat and subcutaneous fat, BMI and WC can be considered as an appropriate obesity index while WHR cannot appropriately apply the abdominal fat amount. Moreover, the study indicates that abdominal obesity group based on the ratio of visceral fat/subcutaneous fat has more significant difference than the abdominal obesity group based on the WC in case of blood lipid index.

Objective: In the present study, we investigated the protective effects of low-intensity treadmill training in doxorubicin-induced cardiotoxicity rat models. Design: Randomized controlled trial. Methods: In this study, we randomly divided them into four groups. The normal group included non-cardiotoxicity normal control (n=10), the control group included non-treadmill training after doxorubicin-induced cardiotoxicity (n=10), the experimental group I included low-intensity treadmill training (3 m/min) after doxorubicin-induced cardiotoxicity (n=10), and the experimental group II included low-intensity treadmill training (8 m/min) after doxorubicin-induced cardiotoxicity (n=10). Rats in the treadmill training group underwent treadmill training, which began at 2 weeks after first intraperitoneal injection. We determined the body weight change for each rat on days 1 and 21. Biochemical markers (lactate dehydrogenase [LDH], creatine kinase [CK], glutathion, aspartate transaminase [AST], and alanine transaminase [ALT]) concentration in the serum change of rats from all four groups was examined at the end of the experiment. Results: The results showed that the experimental group I and II showed a significant increase in body weight as compared with that of the control group (p<0.05). We observed that the biochemical markers (LDH, CK, glutathion, AST, and ALT) were improved in the experimental group I than the experimental group II (p<0.05). There was no difference between the experimental groups. Conclusions: In conclusion, our data suggest that low-intensity treadmill training applied after doxorubicin treatment protects against cardiotoxicity following treatment, possibly by enhancing antioxidant defenses and inhibiting cardiac muscle cell apoptosis.

[Purpose] This preliminary study aimed to develop a regression model to estimate the resting metabolic rate (RMR) of young and middle-aged Koreans using various easy-to-measure dependent variables. [Methods] The RMR and the dependent variables for its estimation (e.g. age, height, body mass index, fat-free mass; FFM, fat mass, % body fat, systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse pressure, and resting heart rate) were measured in 53 young (male n = 18, female n = 16) and middle-aged (male n = 5, female n = 14) healthy adults. Statistical analysis was performed to develop an RMR estimation regression model using the stepwise regression method. [Results] We confirmed that FFM and age were important variables in both the regression models based on the regression coefficients. Mean explanatory power of RMR₁ regression models estimated only by FFM was 66.7% (R²) and 66.0% (adjusted R²), while mean standard errors of estimates (SEE) was 219.85 kcal/day. Additionally, mean explanatory power of RMR₂ regression models developed by FFM and age were 70.0% (R²) and 68.8% (adjusted R²), while the mean SEE was 210.64 kcal/day. There was no significant difference between the measured RMR by the canopy method using a metabolic gas analyzer and the predicted RMR by RMR₁ and RMR₂ equations. [Conclusion] This preliminary study developed a regression model to estimate the RMR of young and middle-age healthy Koreans. The regression model was as follows: RMR₁ = 24.383 × FFM + 634.310, RMR₂ = 23.691 × FFM - 5.745 × age + 852.341.
