RBL-2H3 세포에서 차조기씨 물 추출물의 항산화성 및 항염증 효과를 알아보기 위하여 DNP-IgE와 HSA로 세포를 활성화시켰다. 활성화된 비만 세포에서 분비되어 나오는 히스타민을 효소적 방법으로 측정하였으며, 염증성 사이토카인 IL-4과 TNF-$\alpha$의 생성량은 ELISA 방법으로 측정하였다. 차조기씨 물 추출물은 농도 의존적으로 항산화 활성이 증가되었으며, $1,000\;{\mu}g$/mL농도에서 DPPH와 hydroxyl radical 소거능이 각각 38.9, 93.1%로 가장 높게 나타났다. 이는 차조기씨에 함유된 130.7 mg/g의 높은 페놀 함량에 기인하여 항산화 효과를 나타내었다. 한편 차조기씨 물 추출물을 처리하지 않은 세포에서는 현저히 높은 양의 히스타민을 분비하였지만, 각 추출물의 농도로 처리시킨 세포에서의 분비량은 유의적으로 감소되었고, IL-4와 TNF-$\alpha$의 분비량 모두 차조기씨 물 추출물을 처리군은 대조군에 비해서 유의적으로 낮은 생성량을 보여주었다. 결과적으로 차조기씨 물추출물은 비만세포에 항원-항체 반응으로 인해 발병되는 제1형 알레르기 반응의 약학적 효능을 가진 것으로 나타나 임상적으로 유용하게 사용될 수 있을 것으로 사용되며, 향후 이에 대한 심층적이고 체계적인 연구가 뒤따라야 할 것으로 생각된다.

The ovarian follicles develop initially from primordial follicles. The majority of ovarian primordial follicles are maintained quiescently as a reserve for the reproductive life span. Only a few of them are activated and develop to an advanced follicular stage. The maintenance of dormancy and activation of primordial follicles are controlled by coordinated actions of a suppressor/activator with close communications with somatic cells and intra-oocyte signaling pathways. Many growth factors and signaling pathways have been identified and the transforming growth factor-beta superfamily plays important roles in early folliculogenesis. However, the mechanism of maintaining the dormancy and survival of primordial follicles has remained unknown for decades. Recently, since the first finding that all primordial follicles are activated prematurely in mice deficient forkhead box O3a, phosphatidylinositol 3 kinase/phosphatase and tensin homolog (PTEN) signaling pathway was reported to be important in the regulation of dormancy and initial follicular activation. With these informations on early folliculogenesis, clinical application can be expected such as in vitro maturation of immature oocytes or in vitro activation of follicles by PTEN inhibitor in cryopreserved ovarian cortical tissues for fertility preservation.

The chemical composition and stabilities of the purified ginseng invertase were investigated. The purified enzyme was found to be a glycoprotein composed of 80.2% protein and 19.7% total sugar. The protein component of the enzyme was composed of acidic amino acid (9.3%), basic amino acid (48.9%), nonpolar amino acid (21.4%), polar amino acid (20.4%) and 6.1% S-containing amino acid. It showed especially high contents of histidine and serine. The enzyme was inactivated almost completely by the treatment with some proteases (papain, pepsin. trypsin, pancreatin and microbial alkaline pretense) and protein denatllrants (8M urea and 6M guanidine-HC1), bolt not with glyrosidase (${\alpha}$-amylase, ${\beta}$-amylase. glcoamylese and cellullase). btonosaccharides sllch as glilrose, fructose, galactose and mannose did not exert any influence on the enzyme activity. The activity of the enzyme was inhibited by Ag+, Mn2+, Hg2+, Zn2+ and Al3+, whereas Ca2+, Mg2+, Ba2+ and Fe3+ gave rather activating effects on the enzyme activity. The enzyme was relatively stable in the VH range of VH 6 and 8, and at the temperatures below 35$^{\circ}C$.

The molecular structure of pirprofen, 3-chloro-4-(2,5-dihydro-1H-pyrrol-1-yl)-.alpha.-methyl-benzeneacetic acid, was determined by single crystal X-ray diffraction analysis.

The structure was solved by the direct method and refined by full matrix least-squares procedure to the final R value of 0.034 for 1681 independent reflections. The non-aromatic dihydropyrrol group is found to be coplanar to the central aromatic ring. The molecules are dimerized through the intermolecular hydrogen bonds at the carboxyl group in the crystal.

The crystal structure of metoclopramide, $C_14H_22ClN_3O_2$, has been determined by X-ray diffraction techniques using diffractometer data obtained by the ${\omega}-2{\theta}$ scan technique with Mo $K\alpha$ radiation from a crystal with space group symmetry $P{\overline{1}}$ and unit cell parameters a = 7.500(1), b = 8.707(2), c = 13.292(2) ${\AA}$; ${\alpha}$ = 101.70(2), ${\beta}$ = 81.20(2), and ${\gamma}$ = $114.90(l)^{\circ}$. The sructure was solved by direct methods and refined by full-matrix least-squares to a final R = 0.055 for the 1524 observed reflections. The bent overall-conformation of the molecule seems to be determined mainly by the bifurcated intramolecular hydrogen bond from the amide nitrogen atom to the methoxy oxygen and the amine nitrogen atoms. The crystal packing consists of the hydrogen bonds, ${\pi}-{\pi}$ interaction and hydrophobic interaction.

The 6, 6-dibromopenam 6 was treated with $CH_{3}/MgBr$ and carbaldehyde 5 to afford the 6-bromo-6-(1-hydroxy-1-methyl)penicillanate 7, which was reacted with acetic anhybride to give acetoxy compound 8. The deacetobromination of 8 with zinc and acetic acid gave 6-exomethylenpenams, Z-isomer 9 and E-isomer 10, which were oxidized to sulfones 11 and 12 by m-CPBA. The p-methoxybenzyl compounds were deprotected by $AlCl_{3}$ and neutralized to give the sodium salts 13, 14, and 15.

Purpose: This study is a descriptive research study to determine the level of professional autonomy, professional self-concept, and job satisfaction of emergency nurses, and to investigate their correlations and verify the effects of professional autonomy and professional self-concept on job satisfaction. Method: The subjects were 189 emergency nurses with a work experience of 1 year or more, in 14 hospitals located in B and U Metropolitan Cities. The study was conducted from July 20, 2014, to August 30, 2014. The measurement instruments for professional autonomy, professional self-concept, and job satisfaction were used as the measurement tools. The collected data were analyzed using the t-test, analysis of variance, Scheffe's test, Pearson's correlation coefficient, and multiple linear regression. Results: Job satisfaction among emergency nurses showed a significant positive correlation with professional autonomy (r=.28, p <.001), and with professional selfconcept (r=.50, p <.001) with sub-areas of professional practice (r=.79, p <.001), satisfaction (r=.64, p <.001), and communication (r=.25, p <.001). Factors affecting job satisfaction were satisfaction (${\beta}$=0.60, p <.001), followed by low professional autonomy (${\beta}$=-0.24, p <.001) and communication (${\beta}$=0.14, p =.008), which accounted in total for 48.3% of the effect. Conclusion: This study suggests that enhancing professional satisfaction, maintaining proper communication, and securing autonomy are required to improve the job satisfaction among emergency nurses.

The effect of lipoxygenase (LOX) on the oxidation and co-oxidation of lipid fraction was studied in the model system of rainbow trout. For the reaction in model system 1 g of lipid fraction and 50mL of enzyme extract(LOX, 140 unit in 50mL phosphate buffer solution at pH 7,4)), which were obtained from rainbow trout, were homoginized in the presence of Tween 20 and kept at 23$\circ$C for 3 days. The activity of LOX was decreased to 43% of initial level during the reaction in the model system. The initial composition of rainbow trout lipid was showed to be consisted of trigliceride(TG;82%) and free fatty acid(FFA;0.1%), while this converted to 59% of TG and 20% of FIFA, respectively after reaction in model system. Change of fatty acid composition was also observed and the content of linoleic acid, one of the major fatte acids, was decreased to 13% from 54% in the content of total fatty acids after reaction. The carotenoids in rainbow trout were composed of 0.4% $\alpha$-carotene, 1.6% $\beta$ -carotene, 80% canthaxanthin, 7% lutein and 11% zeaxanthin, thus the canthaxanthin was the major component. This canthaxanthin was the most degraded carotenoid by lipoxygenase catalyzed co-oxidation during the reaction. On the other hand the tocopherol isomers found in the rainbow trout were $\alpha$ and $\beta$ -tocopherol, and $\alpha$-tocopherol had a higher degradation rate by the lipoxygenase catalyzed co-oxidation than of $\beta$-tocopherol in the reaction of model system.
