The flower buds of Sophora japonica L (SF), as a well-known traditional Chinese medicinal herb, have been used to treat bleeding-related disorders such as hematochezia, hemorrhoidal bleeding, dysfunctional uterine bleeding, and diarrhea. However, no specific anti-cancer effect and its molecular mechanism of SF have been described. Thus, we performed in vitro study to investigate if treatment of SF affects activating transcription factor 3 (ATF3) expression and ATF3-mediated apoptosis in human colorectal cancer cells. The effects of SF on cell viability and apoptosis were measured by MTT assay and Western blot analysis against cleaved poly (ADP-ribose) polymerase (PARP). ATF3 activation induced by SF was evaluated using Western blot analysis, RT-PCR and ATF3 promoter assay. SF treatment caused decrease of cell viability and increase of apoptosis in a dose-dependent manner in HCT116 and SW480 cells. Exposure of SF activated the levels of ATF3 protein and mRNA via transcriptional regulation in HCT116 and SW480 cells. Inhibition of extracellular signal-regulated kinases (ERK) 1/2 by PD98059 and p38 by SB203580 attenuated SF-induced ATF3 expression and transcriptional activation. Ectopic ATF3 overexpression accelerated SF-induced cleavage of PARP. These findings suggest that SF-mediated apoptosis may be the result of ATF3 expression through ERK1/2 and p38-mediated transcriptional activation.

Total phenol, flavonoid and antioxidant components of cabbage leaf samples derived from different cultivar were determined. Total phenol compound content showed the highest amount in methanol extracts from ‘YR Howol’ cultivar (11.72 ㎎/g), followed by ‘Harutame’ (10.66㎎/g), ‘Winstar’ (10.34 ㎎/g) and YR Hero (10.20 ㎎/g). The highest amount of total flavonoid content was observed from the methanol extracts of Harutame (5.39 ㎎/g), followed by Winstar (4.28 ㎎/g), Wialhowol (4.10 ㎎/g). The SOD enzyme activity showed a high activity of ‘YR Hogeo’ cultivar, and the cultivar of ‘YR Howol’ cultivar showed the lowest activity of SOD. The activity of CAT and APX showed higher values ‘Ogane’ and ‘YR Hogeol’ cultivars than the other cultivars. The POD activities showed relatively high values ‘Ogane’ and ‘YR Howol’ cultivars compared with other cultivars. The free radical (DPPH) scavenging activity showed lower IC
values of ‘Harutame’ (15.71) and ‘YR Howol’ cultivar (16.88), however methanol extract of ‘YR Hero’ cultivar (22.49) being the highest. The extracts of all cabbage cultivars in the reaction solution of pH 1.2 could be decomposed nitrite more than 50%. Especially, the cultivar ‘YR Hogeol’ and ‘Ogane’ showed a relatively high nitrite scavenging activity for each 60.13% and 57.20% respectively. The IC
values of antioxidant activity determined by ABTS were lower in ‘Harutame’ (17.04) and ‘YR Howol’ cultivar (17.97), and its results observed similar with values obtained from the same extracts by DPPH method. The result of this study suggests that the methanol extract of Brassica oleracea L. contains the high amount of phenolic and higher radical scavenging activities.

Alpiniae officinarum Rhizoma (the rhizome of Alpinia officinarum Hance, known as lesser galangal), a family of Zingiberaceae, has been used to reduce pain of infection and inflammatory diseases in Asian countries. The present study was focused to evaluate the inhibitory degranulation effect of Alpiniae officinarum Rhizoma extract in RBL-2H3 rat basophilic leukemia cells. Cell viability was measured by MTT assay. RBL-2H3 cells were stimulated by phorbol 12-myristate 13-acetate and calcium ionophore A23187. Mast cell degranulation was analyzed by measuring release of β-hexosaminidase in RBL-2H3 cell. Gene expression was measured by qRT-PCR and signaling molecules were detected by immunoblotting. The Alpiniae officinarum Rhizoma extract suppressed β-hexosaminidase release in dose-dependent manner and inhibited cycloxygenase-2 and tumor necrosis factor-α gene expression. Furthermore, it was found that Alpiniae officinarum Rhizoma extract reduced mitogen-activated protein kinases, especially phosphorylated p38, at 0.75 ㎎/㎖ of Alpiniae officinarum Rhizoma extract concentrations. These data show that Alpiniae officinarum Rhizoma extract has immunosuppressive effect in mast cell induced allergic inflammation.

The effect of storage temperature and the storage period of hardy kiwifruits on the fruit firmness, soluble solids and fruit weight were studied in this work. The investigation was carried out on the Sae-Han cultivar of Actinidia arguta. It has an edible smooth skin and contains high amounts of sugar and vitamin C (ascorbic acid). In this research, the measurement of fruit firmness, soluble solids, and fruit weight were carried out at various temperatures (5, 10, 15, and 20℃) during 14 days. Fruit firmness rapidly decreased and soluble solids content increased at 15 and 20℃. We also investigated the correlation between fruit firmness and soluble solids content. There was a strong correlation between fruit firmness and soluble solids content. That means that fruit firmness affect the soluble solids content of hardy kiwifruit.

This study measured the plasma and liver concentrations of cytokines, the distribution of blood lymphocyte subpopulations (CD4 and CD8), plasma levels of nitrite (NO
) and nitrate (NO
), intercellular adhesion molecule 1 (ICAM-1), cytokine-induced neutrophil chemoattractant 1 (CINC-1), prostaglandin E2 (PGE2), and peritoneal lavage fluid (PLF) levels of monocyte chemotactic protein 1 (MCP-1) and CINC-1 in order to examine the anti-inflammatory activity of the cinnamon extract in lipopolysaccharide (LPS)-exposed rats. The plasma concentrations of interleukin (IL)-1β, IL-6, and tumor necrosis factor α (TNF-α) were lower in the cinnamon extract groups than in the control group at both 2 and 5 h after LPS injection. Furthermore, the liver concentrations of IL-1β, IL-6, and TNF-α were lower in the cinnamon extract groups than in the control group at 5 h after LPS injection. Plasma IL-10 concentrations were higher in the cinnamon extract groups than in the control group at both 2 and 5 h after LPS injection, and liver concentrations of IL-10 did not differ significantly among all treatment groups at 5 h after LPS injection. The distribution of CD4 tended to increase, and that of CD8 tended to decrease in the cinnamon extract groups. The CD4/CD8 ratio was increased in the cinnamon extract groups. The plasma concentrations of NO
, ICAM-1, CINC-1, and PGE2 and the PLF concentrations of MCP-1 and CINC-1 exhibited a tendency to decrease in the cinnamon extract groups. These results indicate that cinnamon extract can exert functional anti-inflammatory effects.

Magnoliae Flos (Sini in Korean) is one of the most important oriental medicinal plants. In the Korean Herbal Pharmacopeia, the bud of the all species in Manolia denudate and Manolia genus were regarded as the botanical sources for ‘Sini’. Most the dried bud of Manolia denudata, Manolia biondii and Manolia sprengeri were used as ‘Xin-yi’ in China. Therefore, the purpose of this study was to determine and compare the ‘Magnolia’ species, four species including Manolia denudata, M. biondii, M. liliiflora and M. Kobus were analysis of sequencing data revealed DNA polymorphisms. The based on tRNA coding leucine/phenylalanine (trnL-F) and NADH-plastoquinone oxidoreductase subunit 5 (ndhF) sequences in chloroplast DNA. For the identification of ‘Magnolia’ species, polymerase chain reaction (PCR) analysis of chloroplast DNA regions such as ndhF have proven an appropriate method. A single nucleotide polymorphism (SNP) has been identified between genuine “Sini” and their fraudulent and misuse. Specific PCR primers were designed from this polymorphic site within the sequence data, and were used to detect true plants via multiplex PCR.

Abeliophyllum distichum is a monotypic taxon of Oleaceae and endemic to Korea. A comprehensive study on embryogeny and fruit and seed coat ontogeny in Abeliophyllum was carried out via microtome and light microscopy. The fertilization occurs during mid– to late April and embryo matures by early July. The embryo development follows the general fashion from globular embryo – transition embryo – heart shaped embryo – torpedo embryo – walking-stick embryo to mature embryo. The pericarp clearly differentiates into three histological zones: exocarp, mesocarp, and endocarp. The young seed comprises 10-12 cells thick seed coat and the mature seed coat comprises an exotesta, 6-8 mesotesta and an endotesta. Any crystals, phenolic-like compounds, idioblasts, and the sclereids are not found in pericarp as well as seed coat. An overall development confirms Solanade type of embryogenesis in Abeliophyllum. The endocarp becomes more prominent in mature fruit and all the layers of endocarp are highly lignified. On the basis of mechanical layer the seed coat is of exotestal type.

Carbohydrate sources are one of important factors associated with macro- and micro nutrients and phytohormones in vitro culture medium for shoot growth. The optimal carbohydrates for eight species of the genus Prunus which are economically important fruit crop was evaluated at the initiation and elongation stages. All carbohydrate seemed utilized for the bud break and leaf growth at the early stage of culture. However, shoot elongation and fresh weight of species tested were superior in the medium containing 90 mM of fructose or glucose rather than sucrose. There was no difference between glucose and fructose. Adventitious shoots from the axillary buds were induced in most species but no significant differences were observed except for two species (P. salicina ‘Shiro’ and P. tomentosa). These result demonstrated that glucose and fructose were suitable carbohydrate sources for diverse Prunus species than sucrose, although the response to the carbohydrates in the medium were slightly different in the species.

Sweet potato has low regeneration capacity, which is a serious obstacle for the fruitful production of transgenic plants. Simple and rapid regeneration method from storage root explants of purple sweet potato (Ipomoea batatas L.) was investigated. The embryogenic callus was observed from 4 cultivars and its highest rate was induced at 1 μM 2,4-D after 5 weeks of culture. Result revealed that a low concentration of 2,4-D and low light intensity was important factors for embryogenic callus formation. After subculture on medium with 5 μM ABA for 4 days, subsequently, occurred the regeneration of shoots within 4 weeks when these embryogenic callus was transferred onto the MS hormone free medium. Regenerated shoots were developed into platelets, and grown normal plants in the greenhouse. We developed a simple and quickly protocol to regenerate plantlets in storage root explants of purple sweet potato. This regeneration system will facilitate tissue culture and gene transfer research of purple sweet potato.
