  • Intestinal epithelial cells can produce cytokines and chemokines that play an important role in the mucosal immune response. Regulation of this secretion is important to prevent inflammatory tissue damage. Lonicera japonica have been shown to inhibit inflammation. We tested the effect of luteolin, a major ingredient of Lonicera japonica, on TNF-${\alpha}$-stimulated IL-8 secretion from lntestinal epithelial cells. (omitted)

  • Capsaicin (8-methyl-N-vanillyl-6-nonenamide), a pungent ingredient of hot chili peppers, has been reported to possess substantial anticarcinogenic and antimutagenic activities. In the present study. we investigated the effects of capsaicin on pulmonary metastasis of B 16-F10 murine melanoma cells. as well as its mechanism of action. Capsaicin (i.p.. 2.5mg/kg) suppressed the number of lung colonies (58%) in experimental lung metastasis assay. (omitted)

  • Capsaicin, a pungent ingredient in chili pepper, is known to excite sensory neurons that mediate pain sensation. This effect of capsaicin is determined by unique receptors and the capsaicin receptor (transient receptor potential subfamily V, member 1 (TRPV1)) was cloned recently. TRPV1 contains six transmembrane domains and three ankyrin repeats at N-terminal. This characteristic architecture is common in other ion channel in TRPV families. (omitted)

  • High-performance liquid chromatography (HPLC) screening method revealed that a propolis product marketed as a functional food contained an undeclared substance similar to tadalafil, the active ingredient of the prescription drug Cialis$^{(R)}$ approved for the treatment of male erectile dysfunction. In order to identify the illegal additive, the propolis product was extracted with methylene chloride, and the extract was purified further using semipreparative HPLC. The chemical structure of the isolated substance was elucidated based on IR, LC/MS-ESI, and $^1H$- and $^{13}C$-NMR spectroscopy, which showed the characteristics similar to tadalafil. The only difference was the substitution of the methyl group at the piperazinedione ring of tadalafil to the amino group of the identified illegal additive.

  • The extracts fermented of rice germ are called GMT (Glumate) which is a main ingredient of Condition$^{\circledR}$. It has been reported that GMT reduced the blood concentrations of alcohol in heathy adults. The purpose of the study is to examine the effect of GMT on blood concentrations of ethanol and on heart rate increase induced by ethanol. GMT was administered orally to 15 healthy adults before (10 min) and after (1 h) ethanol ingestion. The oral administration of GMT before (10 min) and after (1 h) ethanol ingestion reduced the area under the blood concentration of ethanol-time curve (p<0.12) and tended to inhibit the ethanol-induced heart rate increase.

  • Inhibitory effects of the essential oils obtained from ten herbs were tested on acetaminophen-induced lipid peroxidation in the rat. The oil of Artemisia princeps var. orientalis buds (AP-oil) showed the most significant hepatic malondialdehyde value which was comparable to those of ascorbic acid and methionine. This was warranted by the protective effect on hepatic glutathione depletion. Overview of the data on the activities of hepatic microsomal enzymes, aminopyrine N-demethylase and aniline hydroxylase led to the notice that the suppressed activities of those enzymes are mainly responsible for the anti-lipid peroxidation. The interpretation of GC-MS data on the AP-oil revealed the ingredient of cineol, thujone, carvone, borneol, camphor and terpineol.

  • Studies on the adsorption of four kinds of bacteria, Staphylococcus aureus, Sarcina lutea, Escherichia coli and Serratia marcescens by activated Korean Kaoline have been carried out to innovate utilization as adsosrbent preparations. In connection with particle size and size fraction, the adsorption was examined by colony counting and spectroscopy. Korean kaolin was purified from Hadong white species of preminum grade and three size fractions were derived from passage through BS # 100, #200 and # 325 mesh sieves, respectively. These were activated at $105^{\circ}$or $280^{\circ}$ for three hours and at $550^{\circ}C$ for one hours. The results indicated that the adsorbing power of Korean kaolin was superior for S. aureus and S. lutea, but E. coli and S. marcescens were not adsorbed by clays. The smaller the particle size, the greater was adsorbing power for Gram-positive bacteria. Threre appears to be justification for its investigations as an ingredient in intestinal adsorbent preparations.

  • A new derivative of tacrolimus was evaluated for its molecular weight, using LC-MS of the tacrolimus bulk active pharmaceutical ingredient (API) recovered through the purification of crude tacrolimus produced by Streptomyces clavuligerus CKD-1119. In addition, the molecular weight of the new derivative of tacrolimus was found to be at m/z 818 and was identified by $^{13}C$-NMR with peak assignments based on the differences in methyl group location resulting from the chemical structure. The structure of the new derivative, an unknown impurity of tacrolimus, was found to be 18-methyltacrolimus through comparison of the spectral data of the structural differences between ascomycin, tacrolimus, and the new derivative 18-methyltacrolimus.

  • Mt. Jiri located in the southwestern part of Korea is a treasure trove of wild medicinal plants. More than 1200 species currently classified as herbs are grown or cultivated in the area. Recently, safflower has attracted interest because of its ability to control fine wrinkle formation on the neck. The objective of this study therefore was to determine whether the active ingredient of safflower could be used in the form of an extract to reduce wrinkle formation in individuals aged 30 to 59 years. In particular, this study was aimed at determining the extract’s elastase activity and anti-oxidant effect by using DPPH assay in vitro and evaluating the anti-wrinkle efficacy of different types of safflower extracts in improving fine wrinkles on the neck. This study will provide a basis for future studies to develop safflower extracts using advanced composition technology and contribute to the development of the herbal cosmetics industry.
