Background : Korean mountain ginseng (Panax ginseng C.A. Meyer) are difficult to industrially apply because of its scarcity and high cost. Advances in plant biotechnology have made it possible to produce mountain ginseng on a large scale using adventitious root cultures in bio-reactors. This study was conducted to develop a cosmetic emulsion using ginsenoside and physiological activity - enhanced raw materials by fermentation process. Methods and Results : Wild ginseng adventitious roots were fermented with Pediococcus pentosaceus HLJG 0702 (KACC 81017BP). ginsenoside contents was analysed by using HPLC. Antioxidant activity was measured by DPPH and ABTS radical scavenging activity and whitening effect was measured by tyrosinase inhibitory activity. After microfluidizer processing was performed to prepare emulsions with homogenized particles, particle size and distribution were measured through a transmission electron microscop e(TEM). Particle stability compares pH, viscosity, light and zeta potential. When fermented with Pediococcus pentosaceus HLJG 0702, the highest change rates of Rg3, Rk1 and Rg5 were shown and the antioxidant activity was increased. The whitening effect was 73.2 ± 0.9% when treated at 100 ㎍/㎖, 1.5 times higher than the control. The optimum particle size and distribution were shown to be 418.0 ± 14.9 ㎚ for 6 times treatment with 0 - 10 times microfluidizer treatment. Stability was about 3% in pH, viscosity and light test. the zeta potential was found to be homogeneous at –33.33 mV. Conclusion : Pediococcus pentosaceus HLJG 0702 Fermented Wild ginseng adventitious roots were found to have effective ingredients and improved physiological activity. We have also developed emulsions that exhibit optimal particle size and distribution

Background : The minor saponins produced by the hydrolysis of a major saponins sugar. The minor saponins has high absorption and efficacy compared to major saponin. The acid treatment, heat treatment and fermentation with minor saponin research has been actively conducted. This study was performed in order to investigate the bioconversion of ginsenoside Rg5 of fermented wild ginseng adventitious roots by using lactic acid bacteria. Methods and Results : 20g adventitious roots of ginseng was added to water (10-fold v/w). 10% (v/v) of lactic acid bacteria (Pediococcus pentosaceus HLJG0702[KACC 81017BP]) were inoculated with wild ginseng adventitious roots. For the fermentation process the inoculated samples were transferred to culture room for 1, 3 and 5 days. The fermented samples were dried at room temperature and extracted with 70% ethanol. Extract was concentrated completely at 50 ℃ and Rg5 was analysed by using HPLC. Results showed no significant difference the dry weight of non-fermented and fermented wild ginseng adventitious roots. During the fermentation process, the pH changed from 5.7 to 4.2. HPLC analysis showed higher ginsenoside Rg5 (39.588 mg/g) at 3 days. Conclusion : The fermentation of ginseng root can increase the Rg5 contents and minor saponin composition. This process may be used to enhance the minor saponin thereby increasing in fermented property of wild ginseng adventitious roots.

Background : As a part of ongoing research to elucidate and characterize anti-inflammatory nutraceuticals, six kinds of plant extracts (aerial part of Nepeta cataria, leaves of Lonicera maackii, leaves of Platycarya strobilacea, flower of Fagopyrum dibotrys, flowers and fruits of Solanum nigrum, stem of Physostegia virginiana) were tested for their ability to suppress inflammation. The anti-inflammatory has been studied in lipopolysaccharide (LPS)-stimulated RAW264.7 cells which cells synthesized nitric oxide (NO) from L-arginine by nitric oxide synthase (NOS). In this study, NO synthesis inhibitory activity of six kinds of plant extracts on LPS-stimulated RAW 264.7 mouse macrophages was evaluated. Methods and Results : Six kinds of plant extracts were parceled out from RDA (Rural Development Administration). RAW 264.7 cells (1.5×105 cells/well) were seeded onto 96-well plates with DMEM media containing 10% FBS and 1% antibiotics. The cells were pretreated with the extracts and LPS-stimulated cells for 24 h. Cellular NO production was stimulated by adding 1 μg/mL of LPS. After incubation, Griess reagent was used to determine NO production. Absorbance was measured at 520 nm by microplate reader. NO synthesis inhibitory activity potential of these extracts was evaluated by assessing NO production by LPS-stimulated RAW 264.7 cells in the presence. As a result, inhibition rate of NO production was about 40% of L. maackii, 33% of F. dibotrys, 23% of P. strobilacea and 17% of P. virginiana. Meanwhile, there was no significant results in aerial part of N. cataria and flowers and fruits of S. nigrum. Conclusion : From the above results, we be able to confirm that leaves of L. maackii and flower of F. dibotrys appeared dose-dependent NO synthesis inhibitory activity and leaves of P. strobilacea appeared NO synthesis inhibitory activity in low-concentration. As screening NO synthesis inhibition of six extracts, they may be a good candidate for delaying the progression of human inflammatory diseases and warrants further studies.

Aromatase is an enzyme that converts testosterone to estrogen. This enzyme, present in the sperm as well as various tissue and cells, has been considered to be related to the fertility of human and mouse sperm. Therefore, we examined effect of aromatase inhibitor on viability and fertility of sperm, and quantity of aromatase in sperm groups with different density in pig. To analyze the effect of aromatase on sperm viability, we treated aromatase inhibitor to the sperm with different concentrations (0, 10, 20, 50, 100, 200, 500 μM) at different time (0.5, 1, 2, 4, 8 hours). After the treatment, the sperm viability was calculated by hypo-osmotic swelling test. We selected 0, 50, 100 μM concentration during 0.5 hour as inhibitor treatment condition before in vitro fertilization. Next, we examined fertility and quantified aromatase protein in sperms with different density. In the first experiment, viability of sperm was decreased following the increasement of inhibitor concentration. The aromatase inhibited sperm showed lower penetration rate and cleavage rate than those of non-treated sperm. Concentration of 50 μM inhibitor had no significant effect on the sperm viability, but it significantly reduced sperm fertility. Second, sperms with low density showed higher penetration rate, but no significant difference between sperms with high density. In conclusion, aromatase is responsible for viability and fertility of porcine sperm similar to mouse and human, however, density of sperm has no correlation with quantity of aromatase protein.

Olive flounder (Paralichthys olivaceus) is one of the commercial important flatfish species in Korea. The ocular signal transduction pathway is important in newly hatched flounders because it is closely involved in the initial feeding phase thus essential for survival during the juvenile period. However, the study of gene expression during ocular development is incomplete in olive flounder. Therefore we examined the expression analysis of specifically induced genes during the development of the visual system in newly hatched flounders. We searched ocular development-involved gene in the database of expressed sequence tags (ESTs) from olive flounder eye and this gene similar to arrestin with a partial sequence homology. Microscopic observation of retinal formation corresponded with the time of expression of the arrestin gene in the developmental stage. These results suggest that arrestin plays a vital role in the visual signal transduction pathway of the retina during ocular development. The expression of arrestin was strong in the ocular system during the entirety of the development stages. Our findings regarding arrestin have important implications with respect to its biological role and evolution of G-protein coupled receptor (GPCR) signaling in olive flounder. Further studies are required on the GPCR-mediated signaling pathway and to decipher the functional role of arrestin.

Cathepsins are members of the multigene family of lysosomal cysteine proteinases and have regulated function in several life processes. The potential role of cathepsin F cysteine gene was expected as protease in the yolk processing mechanism during early developmental stage, but expression analysis was unknown after fertilization. The alignment analysis showed that amino acid sequence of cathepsin F from olive flounder liver expressed sequence tag (EST) homologous to cathepsin F of other known cathepsin F sequences with 87－98% identity. In this study, we examined the gene expression analysis of cathepsin F in various tissues at variety age flounder. Tissue distribution of the cathepsin F mRNA has been shown to be ubiquitous and constitutive pattern regardless of age in each group, although derived from cDNA library using liver sample. The mRNA level of cathepsin F more increased as developmental proceed during embryogenesis and early developmental stage, especially increased in the blastula, hatching stage and 3 days post hatching (dph). As a result, it may suggest that the proteolysis of yolk proteins (YPs) has been implicated as a mechanism for nutrient supply during early larval stages in olive flounder.

Olive flounder (Paralichthys olivaceus) is a most important aquaculture species in Korea. Like most marine fishes, olive flounders are stomachless at first feeding and aquired gastric function during the metamorphosis, so food was mainly digested by pancreatic enzyme from first feeding to premetamorphosis. However, comprehensive analysis of pancreatic and gastric digestive enzyme of olive flounder at early developmental period is still unclear. In the expression study of pancreatic and gastric digestive enzyme by real-time PCR at early developmental stage, pancreatic enzyme such as chymotrypsinogen 2, preproelastase 2 and 4, pancreatic protein somatomedin-B domain (PPSB) mRNA expression were initiated at first feeding and strongly expressed in the pancreas developmental stage, while gastric digestive enzyme signal was not at all detected during same period. Although, trypsinogens were secreted from pancreas and have similar amino acid sequence, trypsinogen 3 expression induction was detected both pancreas and stomach developmental stage, while trypsinogen 2 expression was significantly increased only post-metamorphosis period. Pepsinogen mRNA expression was only detected at metamorphosis according to stomach differentiation. Lipid digestive enzyme, lipase and intestine fatty acid binding protein 1 (I-FABP 1), were already reached a certain level at beginning of hatching and more increased during early developmental stage and then gradually decreased before metamorphosis. These results suggested that feed ingestion of olive flounder was exclusive charged by pancreatic digestive enyme, lipid digestive enzyme and trypsinogen 3 from first feeding and then fully swiched by gastric digestive enzyme and trypsinogen 2 from metamorphosis period.
