Glucosinolates(GSLs) are major secondary products($\beta$-thioglucoside N-hydroxysulfates) containing sulfates that are found mainly in Cruciferae family such as cabbage, broccoli, radish, turnip, kale, mustard and rapeseed as the important crops in agronomic and economic aspects. Especially, isothiocyanates(ITCs) have been shown to inhibit carcinogenesis with regulation cancer cell development followed by regulating target enzymes, inducing cell cycle arrest and apoptosis against various human cancer cell lines. Total desulfo(DS)-GSLs of nine type in 210 Korean leaf mustard accessions were isolated and confirmed using electrospray ionization mass spectrometric(ESI-MS/MS) method and DS-GSLs powerful library maked from several reference data. The isolated individual DS-GSLs were identified by removed $\beta$-D-glucopyranose residue ($C_6H_{11}O_5$, MW 163) from MS/MS data. Among them sinigrin(41.7%), glucoiberverin(21.7%) and gluconasturtiin(12.6%) were major components, Especially, despite gluconapin was minor component, accession K046197-1 and K046197-2 showed higher content of 4.11 and 3.31 mg/g(DW), respectively. The total GSLs contents in 210 accessions were ranged from 5.3 to 23.2 mg/g(DW) with a mean value of 13.0 mg/g(DW). As a result of principal component analysis(PCA), the individual GSLs loading plots were composed of three groups and components belonged to each group showed correlationship in quantitative pattern.

The present study was planned to investigate the role of sex hormone receptor gene expression in the pathogenesis of hepatocellular carcinoma (HCC). Adult male Wistar rats were divided into seven groups. Group (1) was negative control. Groups (2), (5), (6), and (7) were orally administered with N-nitrosodiethylamine for the induction of HCC, then group (2) was left untreated, group (5) was orally treated with curcumin, group (6) was orally treated with carvacrol, and group (7) was intraperitoneally injected with doxorubicin, whereas groups (3) and (4) were orally administered only curcumin and carvacrol, respectively. The HCC group showed significant upregulation in the androgen receptor (AR) and the estrogen receptor-alpha ($ER{\alpha}$) gene expression levels in the liver tissue. On the contrary, HCC groups treated with either curcumin or carvacrol showed significant downregulation in AR and $ER{\alpha}$ gene expression levels in the liver tissue. In conclusion, the obtained data highlight that both AR and $ER{\alpha}$ but not estrogen receptor-beta ($ER{\beta}$) gene expression may contribute to the male prevalence of HCC induced in male rats. Interestingly, both curcumin and carvacrol were found to have a promising potency in alleviating the male predominating HCC.

Nardostachys jatamansi water extract (NJ) has long been used for the treatment of inflammation-and immune-mediated disorders in the oriental countries. However, its site of action and pharmacological mechanism are not fully investigated. In this study, the authors tried to explore the cytoprotective and anti-inflammatory actions of NJ. First of all, NJ has no harmful effects on viability of neuronal cell line HT22 cells in the dose range of 300 mg/ml. On the contrary, it shows cytoprotective effects on the cells treated with reactive oxygen species H2O2. Probably the cytoprotective effects of NJ might be caused by its ability to induce well known cytoprotective gene hem oxygenase-1 (HO-1). Furthermore, NJ shows inhibitory effects on the expression of inducible nitric oxide synthase (iNOS) and NO production which are known to destroy the integrity of both cells and tissues. It also inhibits potent proinflammatory cytokine tumor necrosis factor-alpha (TNF-a) production. The blocking effects of NJ on cytopathic and proinflammatory actions of LPS might be caused by the induction of cytoprotective and anti-inflammatory genes HO-1 in macrophages cell line RAW 264.7 cells. The results in this study suggest NJ could be used for the amelioration of inflammation which is underlying mechanism responsible for most chronic diseases.

Tabanus anticoagulant protein (TAP) was isolated from the whole body of the tabanus, Tabanus bivittatus, using three purification steps (ammonium sulfate fractionation, gel filtration on Bio-Gel P-60, and ion exchange chromatography on DEAE Sephadex gel). The purified TAP, with a molecular weight of 65 kDa, was assessed to be homogeneous by SDS-polyacrylamide gel electrophoresis, and an isoelectric point of 7.9 was determined by isoelectric focusing. The internal amino acid sequence of the purified protein was composed of Ser-Leu-Asn-Asn-Gln-Phe-Ala-Ser-Phe-lle-Asp-Lys-Val-Arg. The protein was activated by $Cu^{2+}\;and\;Zn^{2+}$, and the optimal conditions were found to be at pH $3\sim6\;and\;40\sim70^{\circ}C$. Standard coagulation screen assays were used to determine thrombin time and activated partial thromboplastin time. Chromogenic substrate assays were performed for thrombin and factor Xa activity. TAP considerably prolonged human plasma clotting time, especially activated partial thromboplastin time in a dose-dependent manner; it showed potent and specific antithrombin activity in the chromogenic substrate assay. Specific anti-factor Xa activity in TAP was not detected. Overall, this result suggested that TAP has significant anticoagulant activity on blood coagulation system.

The fibrinolytic enzyme, subtilisin D5, was purified from the culture supernatant of the isolated Bacillus amyloliquefaciens DJ-5. The molecular weight of subtilisin D5 was estimated to be 30 kDa. Subtilisin D5 was optimally active at pH 10.0 and $45^{\circ}C$. Subtilisin D5 had high degrading activity for the A$\alpha$-chain of human fibrinogen and hydrolyzed the $B{\beta}$-chain slowly, but did not affect the $\gamma$-chain, indicating that it is an $\alpha$-fibrinogenase. Subtilisin D5 was completely inhibited by phenylmethylsulfonyl fluoride, indicating that it belongs to the serine protease. The specific activity (F/C, fibrinolytic/caseinolytic activity) of subtilisin D5 was 2.37 and 3.52 times higher than those of subtilisin BPN' and Carlsberg, respectively. Subtilisin D5 exhibited high specificity for Meo-Suc-Arg-Pro-Tyr-pNA (S-2586), a synthetic chromogenic substrate for chymotrypsin. The first 15 amino acid residues of the N-terminal sequence of subtilisin D5 are AQSVPYGISQIKAPA; this sequence is identical to that of subtilisin NAT and subtilisin E.

Objectives: In recent in vitro study, it was reported that osteostatin (OST) has an odontogenic effect and synergistic effect with mineral trioxide aggregate (MTA) in human dental pulp cells. Therefore, the aim of this study was to evaluate whether OST has a synergistic effect with MTA on hard tissue formation in vivo. Materials and Methods: Thirty-two maxillary molars of Spraque-Dawley rats were used in this study. An occlusal cavity was prepared and the exposed pulps were randomly divided into 3 groups: group 1 (control; ProRoot MTA), group 2 (OST 100 μM + ProRoot MTA), group 3 (OST 10 mM + ProRoot MTA). Exposed pulps were capped with each material and cavities were restored with resin modified glass ionomer. The animals were sacrificed after 4 weeks. All harvested teeth were scanned with micro-computed tomography (CT). The samples were prepared and hard tissue formation was evaluated histologically. For immunohistochemical analysis, the specimens were sectioned and incubated with primary antibodies against dentin sialoprotein (DSP). Results: In the micro-CT analysis, it is revealed that OST with ProRoot MTA groups showed more mineralized bridge than the control (p < 0.05). In the H&E staining, it is showed that more quantity of the mineralized dentin bridge was formed in the OST with ProRoot MTA group compared to the control (p < 0.05). In all groups, DSP was expressed in newly formed reparative dentin area. Conclusions: OST can be a supplementary pulp capping material when used with MTA to make synergistic effect in hard tissue formation.

This study investigated the sensory characteristics of mixtures of high-intensity sweeteners for beverage and estimated the shelf life during storage. Sensory characteristics of mixtures of sweeteners (Aspartame/ Acesulfame-K, Aspartame/Sucralose and Acesulfame-K/Stevioside) were evaluated in aqueous (ranging from 90:10 to 50:50) and citrate buffer (ranging from 90:10 to 50:50) solutions. Significant synergistic effects were found in Aspartame/Acesulfame-K and Aspartame/Sucralose mixtures. No significant differences were found in other taste attributes (astringency, bitterness, metallic taste etc.). Aspartame/Acesulfame-K 5:5 solution showed the most acceptable sensory attributes. $Q_10$ values of Aspartame and Acesulfame-K mixture in citrate buffer (ranging from 90:10 to 50:50) solution were calculated from the temperature data (between $40^{\circ}C\;and\;50^{\circ}C$) determined by HPLC. $Q_10$ values were in the range of 2.01-2.25. Their shelf lives were calculated to be lengthened with increasing Acesulfame-K mixture ratio. Their shelf lives in Aspartame/Acesulfame-K 5:5 citrate buffer solution estimated at $20^{\circ}C\;and\;30^{\circ}C$ were 178 days and 88 days, respectively.
