  • A peony is perennial plant which comes under Paeoniaceae. The anatomical differences in root and stem of Paeonia lactiflora Pallas and Paeonia obovata Maxim. are studied. The length of the vessel members of P. lactiflora Pallas is a bit longer than that of P. obovata Maxim. in the stem and the roots, and the width of the vessel members of P. lactiflora Pallas is wider than that of P. obovata Maxim. in the stem and the root. The secondary xylem in the root of P. lactiflora Pallas is discontinuos scalariform arrangement while that of P. obovata Maxim. is continuous radical arrangement.

  • In order to know the toxic effect and carcinogenic activity in rats and mice fed with juice of Korean native Petasites japonicus Maxim of its pellet(4% or 8%) which were dried, milled and mixed with basal diet, the investigations were carried out by macroscopy and histopathology. Macroscopically, although remarkable changes were not observed in the liver of mice, there were slight to moderate swelling of rat livers in the whole groups at 12 to 14 weeks after feeding and milky spots in rats fed with its juice and 8% pelleted Petasites japonicus Maxim diet and a normal diet for 1 week alternatively for 14 weeks. Moreover, moderate to severe swelling and milk spots were recognized in livers of all rats fed with its juice and 8% pellet or 8% pelleted Petasites japonicus Maxim for 16 weeks. But, in cases of rats fed with its juice and 4% pellet or 4% pelleted Petasites japonicus Maxim, only swelling of livers was recognized moderately or severely. Histopathologically, major lesions were found in livers of both rats and mice. There were congestion, hemorrhage, fatty change, focal necrosis, megalocytosis and hyperplasia of endothelial cell in livers of mice and rats, the additional lesions such as proliferation of bile duct and nodular regeneration with diffuse regenerating cells were seen in livers of rats. In addition, preneoplastic lesions, the areas of milky spots macroscopically, were observed in livers of rats fed with Petasites japonicus Maxim for 14 to 16 weeks. In a few cases, haemangioendothelial sarcoma in livers was detected in rats fed with Petasites japonicus Maxim for 16 weeks. Petasites japonicus maxim growing naturally in Korea seem to exhibit toxic effect especially in liver and it contained a causative agent of primary liver tumors.

  • The morphological characteristics of the Korean Scopolia japonica Maxim., commonly known as 'Mi-chi-gwang-i-pul' in Korean, were re-evaluated in comparison with results from previous research, while the distribution map was formulated according to existing flora and voucher specimens. The result of the re-evaluation has shown that there are some distinctive discrepancies compared to the previous reports of some characteristics such as the color of the basal stem, numbers of lateral veins, apex shape of calyx and corolla including the color of corolla. The Korean Scopolia japonica Maxim is found throughout Korea except Jeju-do province. The intra-specific species such as S. parviflora (Dunn.) Nakai, S. lutescens Y.N. Lee and S. kwangdokensis Y.N. Lee were treated as synonyms of S. japonica Maxim. in this research.

  • The methanolic extract of Glycine maxim increased the expression of the promoter in B16 mouse melanoma cells harboring a tyrosinase promoter. Extract concentrations of 10 ${\mu}g/m{\ell}$ and 100 ${\mu}g/m{\ell}$ resulted in tyrosinase promoter expression rates of approximately 113% and 184%, respectively, as compared to the control. The fraction layers consisting of butyl alcohol and methylene chloride improved expression effects on the tyrosinase promoter. In particular, the butyl alcohol fraction evidenced a high expression rate at 100 ${\mu}g/m{\ell}$. In the MTT assay, the methanolic extract did not evidence cytotoxicity at concentrations under 500 ${\mu}g/m{\ell}$. Therefore, the results observed with the extract of Glycine maxim showed that the substance exerted a positive effect on the tyrosinase promoter.

  • During the screening for inhibitors of melanin biosynthesis from plant extract, Angelica polymorpha MAXIM which showed a high level of inhibition was selected. The inhibiting substances were purified form methanol extract of Angelica polymorpha MAXIM followed by silica gel column chromatography and HPLC. The inhibitors were identified as heraclenin, isosaxalin and heraclenol 3'-Me ether, by spectrescopic methods of ESI-MS, H-NMR, C-NMR, DEPT, HMQC and HMBC. These compounds did not have mushroom tyrosinase inhibitory activity, but showed a highly potent melanin biosynthesis inhibition zone in the plate culture of Streptomyces bikiniensis, a bacterium used as an indicator organism in this work. These compounds did not show any growth inhibition against S. bikiniensis at the same concentration of melanin biosynthesis test.

  • BACKGROUND: Yeast biotechnology finds applications in various industries. Hence, we sought to explore the yeasts associated with the flower of Aster spathulifolius Maxim. This study aimed to isolate yeasts from the flower of the plant and screen for biosurfactant-producing yeasts. METHODS AND RESULTS: We collected flowers of Aster spathulifolius Maxim. and performed pure isolation using four types of media. In total, 117 strains belonging to 4 genera, namely, Cryptococcus (75 strains), Aureobasidium pullulans (30 strains), Candida (11 strains), and Rhodotorula (1 strain), were isolated and identified by ITS sequencing. Upon in-depth analysis, Cryptococcus, the most dominant genus (75 strains) was categorized into the 'Unknown group'. Upon in-depth analysis of A. pullulans, we discovered the 'Unknown group I' (27 strains) and the 'Unknown group II' (2 strains), which have not been reported previously. Two A. pullulans isolates with potent surfactant activity were selected via the screening procedure. CONCLUSION: In this study, a total of 117 strains were isolated from the flower of Aster spathulifolius Maxim. In addition, two biosurfactant-producing yeasts were identified from among the isolated yeasts.

  • The Methylene Chloride(MC) fraction of Trichosanthis kirilowii Maxim has been investigated anti-tumor activities in vitro. The MC fraction of Trichosanthis kirilowii Maxim significantly inhibited the proliferation of human leukemic U937 cell with an IC50 of approximately 10μg/ml in a dose-dependent manner. We found that the MC fraction upregulated of caspase9 and caspase-3 activity and cleaved PARP expression but it didn't affect bax and bcl-2. which were demonstrated by western blot analysis. Taken together, these results exerted that the MC fraction suppessed human leukemic U937 cell proliferation by inducing apoptosis, suggesting the MC fraction of Trichosanthis kirilowii Maxim is possible to show anti-cancer activity in vivo.

  • There are lots of sexual images in the contemporary media, and this is due to many of the media formats, such as television, magazines, and the Internet, using these images to relay various messages to the people. The media uses these sexual images (i.e. woman in a bikini) in order to use sex and eroticism as a marketing tool to the audience. Unlike other men's magazines, which actually have many female readers, Maxim magazine's readers are made of mostly men, and because of this, their magazine covers are usually filled with sexy women celebrities, such as singers or actors; images that can attract the general men. This study puts its focus on evaluating Maxim magazine's marketing strategy. The strategy of targeting men in their 20's and 30's, who were not interested in reading, but were impulsive and visually oriented. The study looked at magazine covers from November 2002 (the start of the magazine) to October 2008 (the peak period of its sales), and a total of 72 images were analyzed. For each image, 5 things were recorded (model's occupation, clothing style, hairstyle, makeup, pose and gaze).
