The purpose of this study was to analyze the effects of fashion life style factors on appearance management behavior and to show how self-monitoring influences appearance management behaviors. Subjects for the study were men aged in their thirties and forties living in Seoul and Gyeonggi province. For the purpose of the study, the survey was conducted using convenience samples. A total number of 370 questionnaires were used for data analysis. For statistical analysis, factor analysis and multiple regression analysis were performed. The results of this study indicated that a fashion lifestyle was composed of four factors-fashion/appearance-oriented factor, ostentation-oriented factor, rational consumption- oriented factor, and dignity-oriented factor. The dependent variable of the study was appearance management behavior. Appearance management behavior consisted of interest in skin care and interest in fashion. A statistical analysis of multiple regression revealed that a fashion life style significantly influenced interest in skin care and interest in fashion. When subjects were categorized into two groups by self-monitoring, both respondents with high and low self-monitoring showed that fashion/appearance oriented factors significantly influenced interest in skin care. Fashion/appearance oriented factor influenced interest in skin care more for the subjects with high self-monitoring than for those with low self-monitoring. In contrast, fashion/appearance oriented factors had greater influence on interest in fashion for those subjects with low self-monitoring than those with high self-monitoring.

We have synthesized protoberberine derivatives from tetra- hydroberberinium perchlorate. On quaternization of a several protoberberine derivativese with methyl iodide, the formation of the cis methiodides the corresponding trans methiodides increased according to the order of the bulkiness of the 14-substituent as H>CH₃>CN. The N-methyl signal of the cis 14-substituted quinolisidine methiodides was conformed to appear at higher field than those of the corresponding trans methiodides except for the 14-cyano methiodides in their NMR specta.

Two phenolic allopyranosides and two phenolic amide allopyranosides, along with eight known phenolic compounds, including cimicifugic acids, shomaside B, fukiic acid, isoferulic acid, and piscidic acid, were isolated from the n-butanolic extract of rhizomes of Cimicifuga heracleifolia. On-line spectroscopic data for UV, NMR, and MS from a combination of LC-NMR and LC-MS techniques directly and rapidly provided sufficient structural information to identify and confirm all the structures of major phenolic compounds in the extract, in addition to their HPLC profiles. This combined analytic information was then used as a dereplication tool for structure-guided screening in order to isolate unknown phenolic compounds in the extract. Successive fractionation and purification using semi-preparative HPLC acquired four unknown allopyranosides, and their structures were identified as cis-ferulic acid 4-O-${\beta}$-D-allopyranoside, trans-ferulic acid 4-O-${\beta}$-D-allopyranoside, trans-feruloyltyramine 4-O-${\beta}$-D-allopyranoside, and trans-feruloyl-(3-O-methyl)dopamine 4-O-${\beta}$-D-allopyranoside, based on a subsequent spectroscopic interpretation.

<P>Abnormalities in skin pigmentation can produce disorders such as albinism or melasma. There is a research need to discover novel compounds that safely and effectively regulate pigmentation. To identify novel modulators of pigmentation, we attempted to purify compounds from a bioactive fraction of the Korean medicinal plant<I> Artemisia capillaris</I> Thunberg. The novel compound isofraxidin 7-<I>O</I>-(6′-<I>O</I>-<I>p</I>-coumaroyl)-<I>β</I>-glucopyranoside (compound<B> 1</B>) was isolated and its pigmentation activity was characterized in mammalian melanocytes. Compound<B> 1</B> stimulated melanin accumulation and increased tyrosinase activity, which regulates melanin synthesis. Moreover, compound<B> 1</B> increased the expression of tyrosinase and the key melanogenesis regulator microphthalmia-associated transcription factor (MITF) in melanocytes. Compared to the parent compound, isofraxidin, compound<B> 1</B> produced greater effects on these pigmentation parameters. To validate compound<B> 1</B> as a novel hyperpigmentation agent in vivo, we utilized the zebrafish vertebrate model. Zebrafish treated with compound<B> 1</B> showed higher melanogenesis and increased tyrosinase activity. Compound<B> 1</B> treated embryos had no developmental defects and displayed normal cardiac function, indicating that this compound enhanced pigmentation without producing toxicity. In summary, our results describe the characterization of novel natural product compound<B> 1 </B>and its bioactivity as a pigmentation enhancer, demonstrating its potential as a therapeutic to treat hypopigmentation disorders.</P>

Yim, Soon-Ho,Kim, Hyun-Jung,Lee, Ik-Soo The Pharmaceutical Society of Korea 2003 Archives of Pharmacal Research Vol.26 No.10
Preliminary microbial metabolism studies of bisphenol A (BPA) (1) on twenty six microorganisms have shown that Aspergillus fumigatus is capable of metabolizing BPA. Scale-up fermentation of 1 with A. fumigatus gave a metabolite (2) and its structure was established as bisphenol $A-O-{\beta}-D-glucopyranoside$ (BPAG) based on spectroscopic analyses.

Cirsium rhinoceros Nakai (Compositae) is a herbaceous perennial native to Korea, whole plant of which has been used in folklore medicine. C. rhinoceros was extracted by a standard extraction procedure. Its n-hexane, $CHCl_3$ and n-BuOH extracts were fractionated by column chromatography to provide a polyacetylene, a coumarin and five flavonoids. Ciryneol C, scopoletin, acacetin, cirsimarin were isolated for the first time from this plant.

BACKGROUND:: Inactive and active phases of hepatitis B e antigen-negative chronic hepatitis B virus (HBV) infection are diagnosed by serum HBV DNA levels, with cutoff at 2000 IU/mL. However, it is difficult to distinguish inactive carriers at a single time point because HBV DNA levels can transiently decrease to <2000 IU/mL even in noninactive carriers. GOALS:: We aimed to establish the role of serum hepatitis B surface antigen (HBsAg) in identifying “true inactive carriers” among treatment-naive genotype C HBV-infected patients with low viremia. STUDY:: A total of 133 hepatitis B e antigen-negative carriers with serum HBV DNA levels of <2000 IU/mL and normal alanine aminotransferase levels were enrolled and followed up for >12 months. RESULTS:: Forty patients (30.1%) were classified as noninactive carriers (HBV DNA ≥2000 IU/mL and/or alanine aminotransferase >40 IU/L) during 12 months from enrollment. No baseline serum HBV DNA levels could identify true inactive carriers with 100% specificity, whereas baseline serum HBsAg levels (50 IU/mL) identified true inactive carriers with 100% specificity and 29% detection rate. Detection rate increased when different cutoff levels were applied to different age groups according to median age (46 y). It was comparable in both younger and older groups (37.2% vs. 38%) even when HBsAg cutoff level was increased in the former (400 vs. 50 IU/mL). Furthermore, none reversed to noninactive phase during long-term follow-up when these cutoff levels were applied. CONCLUSIONS:: Baseline serum HBsAg levels at a single time point can identify persistently true inactive carriers, with different cutoff levels according to age.
EFFECT OF TITANIUM SURFACE ROUGHNESS ON CELL ADHESION OF HUMAN OSTEOBLAST-LIKE CELLS (MG63)
Yim Soon-Ho The Korean Academy of Prosthodonitics 2004 대한치과보철학회지 Vol.42 No.3
Statement of problem. The effects of surface roughness have not or insufficiently been analyzed on earlier events such as cell adhesion though cell behavior most germane to implant performance is cell adhesion. Purpose. The purpose of this study was to evaluate cell adhesion of osteoblast-like cells (MG63) onto three types of titanium disks with varying roughness using the Elisa assay. Materials and methods. Representative disks from each group (SLA, HA, machined) were subjected to surface analysis and surface roughness was measured by the optical interferometer (Accura 2000, Intekplus Co., Seoul, Korea). Following this, MG63 cells were cultured on the titanium disks and released. Cell adhesion measurements using the Elisa assay were performed specifically at three points: after 24, 48, and 72 hours of culture. Results. Among the 3 types of surface analyzed, the SLA surface was the roughest with a Ra value of $1.114{\mu}m$ followed by HA coated surface and machined surface, consecutively. The optical density values for the SLA surface group was significantly higher than that of the machined and HA coated surface groups following 24 and 48 hours of culture. The cell culture on HA coated surface showed significantly higher values compared to the machined surface following 24, 48 and 72 hours of culture. Conclusion. The results suggest that surface treatment of titanium surfaces enhanced cell adhesion of human osteoblast-like cells (MG63).
