The purpose of this study was to investigate the obesity and state of dietary intake of 216 young Korean females, and the influence of $\beta$-II, III Adrenergic receptor (AR) gene polymorphism upon obesity and dietary intake. The average weight, height and BMI of the subjects were 160 cm, 54 kg, and 20.9 kg/$m^2$, respectively. The average triceps skinfold thickness, waist circumference, hip circumference and WHR were 21.7mm, 73.1cm, 93.3cm and 0.78, respectively. The results of body composition measurement using bioimpedance method, average body fluid, body protein, mineral mass and body fat were 29.271, 7.22 kg, 6.79 kg and 19.16 kg, respectively. A dietary survey was conducted using 24-hour recall method. Average calorie intake was 1621 ㎉, which is 81% of Korean RDA. We detected 182 (84.3%) Gln27 (QQ) homozygotes and 34 (15.7%) Gln27Glu (QE) heterozygotes for $\beta$-II AR polymorphism. For $\beta$-III AR polymorphism, we detected 163 (75.5%) Trp64 (WW) and 53 (24.5%) Trp 64Arg (WR). The results of comparing of obesity by $\beta$-II AR gene polymorphism, obesity index and BMI of QE type were slightly higher than those of the QQ type. For $\beta$-III AR gene polymorphism, the mean BMI, obesity index, fat mass and percent body fat (%) of the WR type were significantly higher than those of the WW type (p < 0.05). These findings suggest that genetic variability in the human $\beta$-III AR is associated with obesity among young Korean females. We also evaluated the effect of the simultaneous presence of the $\beta$-II AR and $\beta$-III AR polymorphism on obesity. We found that the BMI and obesity index of the mutant type in both $\beta$-II AR and $\beta$-III AR were significantly higher than those of the type that has only one gene mutation or has no mutation (p < 0.05), indicating a synergistic effect of $\beta$-II AR and $\beta$-III AR polymorphism on obesity. No association was found between $\beta$-II Ad or $\beta$-III AR polymorphism and dietary intake.

Objectives : The aim of the present study was to observe the effect of Astragali Radix Herbal-Acupuncture Solution(AR-HAS) at $ST_{36}$(jok-samni, $Z\acute{u}s\bar{a}n$ Li) on collagen- II -induced arthritis(CIA) in mice. Methods : DBA/1J mice were immunized with bovine type II collagen(CII) on days 0 and 21 to induce arthritis. The mice were divided into 5 groups : normal group(no CIA), control group(CIA+no treatment), needle prick group(CIA+single prick with an injection needle), saline group(CIA+saline injection) and ARHA group(CIA+ R-HA treatment). The needle prick, saline injection, and AR-HA groups were injected on the right $ST_{36}$(jok-samni) of mice for 9 weeks, 3 times a week, beginning 4 weeks after the booster immunization. Results : 1. The incidence of arthritis, AI(arthritis index), and joint edema decreased in the AR-HA group. 2. Weight gain, hypertrophy of the spleen, adhesion of the tissues, and transformation of the joint were restrained in the AR-HA group. 3. The concentrations of $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, $IFN-{\gamma}$ in CIA mouse serum and $IFN-{\gamma}$, IL-10 in the CIA mouse spleen cell culture decreased significantly at $ST_{36}$ in the AR-HA group. 4. Total cell counts increased significantly, and the ratio of $CD3e^+$ to $CD45R^+$, $CD4^+$ to $CD8^+$, and $CD4^+$ to $CD25^+$ cells decreased significantly at $ST_{36}$ in the CIA mouse spleen cell culture of the AR-HA group. 5. Total cell counts decreased significantly, and $CD4^+/CD25^+$ and $CD45R^+/CD69^+$ decreased significantly at $ST_{36}$ in the CIA mouse lymph nodes of the AR-HA group. 6. $CD3e^+/CD69^+$ and $CD11b^+/Gr-1^+$ cells decreased significantly at $ST_{36}$ in the CIA mouse joints of the AR-HA group. 7. The histological examination showed that cartilage destruction and synoviocyte proliferation decreased in the CIA mouse joints of the AR-HA group, and collagen fiber was expressed similar to that seen in the normal group. Conclusions : Our experiments show that at $ST_{36}$, an anti-inflammatory mechanism of AR-HA controls synovial cell proliferation and protects against cartilage destruction in rheumatoid arthritis.

Objective : Allergic rhinitis(AR) is an inflammation or irritaion of nasal mucosa. Usually, serum cytokine is regarded as one of the most important factors in AR. Coisis semen have been used for the diseases in digestive organs in traditional chinese medicine. Nowaday, there were some studies reported about the effects of coisis semens on serum cytokine. However the results of theses studies were varies, and moreover there was no study which have used AR animal model. Therefore this study is aimed to determine therapeutic effects of coisis semen extract by observing changes of serum cytokine(IgE, TNF-${\alpha}$, IL-$1{\beta}$, IFN-${\gamma}$ and IL-13) with AR animal model. Methods : Thirty BALB/c mice were divided into six groups : Normal group, Control group, sample I, sample II, sample III, sample IV. Except for Normal group, all the mice in other 5 groups were sensitized intraperionealy by 0.1% ovalbumin solution three times at intervals of one week. Then intranasal sensitization was performed by diffusing 0.1% ovalbumin solution three times at intervals of two days. Normal group were used Normal Saline instead of ovalbumin solution. After the first day of study, sample I, sample II, sample III, and sample IV were orally administrated coisis semen extract by 100mg/kg, 200mg/kg, 500mg/kg, and 1g/kg respectively for 28days. Then, the changes of serum IgE, TNF-${\alpha}$, IL-$1{\beta}$, IFN-${\gamma}$ and IL-13 were observed in 6 groups. We used the statistical methods of ANOVA, post hoc by duncun, and Kruskal-Wallis test(p<0.05) Results : There were statistical changes in IgE and TNF-${\alpha}$. But, there were no statistical changes in IL-$1{\beta}$, IL-13 and IFN-${\gamma}$. Conclusions : According to above results, it is supposed that coisis semen extract has not some significant effects on cytokine of AR animal model. There was no evidence for using coisis semen in relieving symptoms of allergic rhinitis.

To investigate the properties of the narrow-line regions and the accretion disks of YRGs, we study a sample of 28 young radio galaxies (YRGs) observed with the Kast Double Spectrograph at the Shane 3-m telescope and with the DBSP (Double Spectrograph for the Palomar 200-inch Telescope) at Palomar observatory. In addition we collect an addition sample of 15 YRGs with the optical spectra from the SDSS archive. We present the measured narrow-line region properties based on the various emission line ratios, i.e., [O III]/$H{\beta}$, [N II]/$H{\alpha}$, [S II] 6716/6731, [O I]/[O III], [O II]/[O III] and [Ar III]/[O III], which are useful to constrain the gas properties and the states of the accretion disk. We will discuss the characteristics of YRG.

Classification of esterase isozymes of the apterous green peach aphids (Myzus persicae Sulzer) collected in tobacco fields were investigated by the native polyacrylamide gel electrophoresis (PAGE). A total of twelve esterase bands were identified in adult apterous aphid, and the difference of enzyme band activity in the clones was observed at the first and second bands group. Esterases of green peach aphids reacted with specific substrate were more stained $\alpha$-naphthyl acetate than $\alpha$-naphthyl propionate, and $\alpha$-naphthyl acetate more than $\beta$-naphthyl acetate. Twelve esterases on the basis of inhibition by the three types of inhibitors (organophosphates: 2.5$\times$10$^{-3}$ M paraoxon, 4$\times$10$^{-3}$ M DFP; eserine sulfate : 2$\times$10$^{-3}$ M eserin; sulfhydryl reagents: 2$\times$10$^{-3}$ M p-HMB) were classified into three class, namely, cholinesterase (ChE) I, II, carboxylesterase (CE) and arylesterase (ArE), and these classes contained 3, 4, 3 and 2 isozymes, respectively.

The seed coat of the black soybean contains 3 main anthocyanins such as delphinidin-3-O-$\beta$-glucoside, cyanidin-3-O-$\beta$-glucoside, and petunidin-3-O-$\beta$-glucoside. As a part of our effort on discovering and breeding new black soybean cultivars which possesses specific anthocyanin component rich, we determined the anthocyanin profiles of the 2 cultivars recently developed soybean cv. Gaechuck #1 and cv. Gyeongsang #1, using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and compared their content and identity with those of previously known 10 cultivar controls. The Cosmosil-$5C_{18}$-AR-II column were selected for the analysis because of the best peak separation. The column temperature was set up at $35^{\circ}C$. The mobile phase consisting of water containing 0.5%(v/v) formic acid and methanol gave good separation between the 3 anthocyanin analytes and internal standard (quercetin 3-O-$\beta$-rutinoside) and peaks with suppressed tail. The MS/MS spectra of each individual anthocyanin standard were detected in positive electron spray ionization (ESI) modes. It was disclosed that the anthocyanin contents of the soybean cv. Gaechuck#1 and cv. Gyeongsang#1 are roughly higher than those of the 10 controls.

Background: Several risk factors leading to malignant transformation of hydatidiform moles have been described previously. Many studies showed that prophylactic chemotherapy for high risk hydatidiform moles could significantly decrease the incidence of malignancy. Thus, it is essential to discover a breakthrough to determine patients with high risk malignancy so that prophylactic chemotherapy can be started as soon as possible. Objectives: Development of a scoring system of risk factors as a predictor of hydatidiform mole malignant transformation. Materials and Methods: This research is a case control study with hydatidiform mole and choriocarcinoma patients as subjects. Multiple logistic regression was used to analyze the data. Odds ratios (OR), attributable at risk (AR : OR-1) and risk index ($ARx{\beta}$) were calculated for develoipment of a scoring system of malignancy risk. The optimal cut-off point was determined using receiver operating characteristic (ROC) curve. Results: This study analyzed 34 choriocarcinoma cases and 68 benign hydatidiform mole cases. Four factors significantly increased the risk of malignancy, namely age ${\geq}35$ years old (OR:4.41, 95%CI:1.07-16.09, risk index 5); gestational age ${\geq}$ 12weeks (OR:11.7, 95%CI:1.8-72.4, risk index 26); uterine size greater than the gestational age (OR:10.2, 95%CI:2.8-36.6, risk index 21); and histopathological grade II-III (OR:3.4, 95%CI:1.1-10.6, risk index 3). The lowest and the highest scores for the risk factors were zero and 55, respectively. The best cut-off point to decide high risk malignancy patients was ${\geq}31$. Conclusions: Malignant transformation of hydatidiform moles can be predicted using the risk scoring by analyzing the above four parameters. Score ${\geq}31$ implies high risk patients so that prophylactic chemotherapy can be promptly administered for prevention.
