This study was conducted to evaluate the hair-growth promotion effect in C57BL/6 mice of a new substance mixed with Allium cepa (red)-bioconversion extract and Angelica gigas Nakai. The ethanol extract of Allium cepa (red) was bioconverted through the use of the Bacillus subtilis KJ-3 (BS3) strain, which was named Red-BCQ. The quercetin content of Red-BCQ increased by about 7.4-fold after bioconversion. Angelica gigas Nakai extract (Agnex) contains a large amount of coumarins such as decursin (D) and decursinol angelate (DA). A 1 mg portion of Agnex contained 0.4146 mg of D and 0.3659 mg of DA. Minoxidil has been known to promote hair growth. In this study, the hair-growth promotion effects of Red-BCQ, Agnex, and a mixture of both Red-BCQ and Agnex were compared with 5% minoxidil. Twenty-five mice were divided into five experimental groups including saline (CON), 5% minoxidil (PCON), Red-BCQ (RA), Agnex (AG), and a Red-BCQ-Agnex mixture (RAG)-treated group. Samples were administered orally once a day at a fixed time for 4 weeks. Hair growth was monitored by photograph at 7, 14, 21, and 28 days. We also observed 5α-reductase, alkaline phosphatase (ALP), γ-glutamyl transpeptidase (γ-GT), insulin-like growth factor (IGF)-1, transforming growth factor (TGF)-β1, antioxidant enzyme, and the hair follicles of the skin tissue. In all the results, the RAG-administered group showed greater antioxidative and hair-growth promotion effects than the other groups. These data suggest that RAG has potent stimulating activity on hair growth in C57BL/6 mice.

Bound lipids(BL) of naked barley(Hordeum vulgare L.) were extracted by different methods and the composition of BL was determined by the procedures of column chromatography, thin layer chromatography and gas chromatography. For the extraction, after free lipids were removed from barley flour by petroleum ether(PE) extraction and then BL were extracted from PE treated flour by the solvent systems of water-saturated butanol(WSB) at $25^{\circ}C$(WSB-LT) and at $95^{\circ}C$ (WSB-HT). BL were extracted by WSB-HT with higher extraction yield as 1.5% as dry basis of flour. The contents of neutral lipids(NL), glycolipids(GL) and phospholipid(PL) in BL were $20.7{\sim}35.5%$, $28.7{\sim}32.4%$, $32.1{\sim}50.6%$, respectively with particularly higher content of PL in WSB-HT as 50.6%. Digalactosyl-diglycerides $(40.2{\sim}44.8%)$, monogalactosyl-diglycerides $(20.3{\sim}31.1%)$, sterly glycerides$(11.2{\sim}15.2%)$ and cereb rosides$(11.6{\sim}12.9%)$ were observed in GL. Of the PL in BL, lysophosphatidyl choline, phosphatidyl choline and phosphatidyl serine, and phosphatidyl ethanolamine were the major components. The predominent fatty acids of NL, GL and PL were linoleic and palmitic acids, however, no significant difference was observed in the composition of fatty acids between two extraction methods.

The angiotensin I-converting enzyme (ACE) inhibitor has anti-hypertensive effects and has long been used as prevention or remedy of hypertension. This study were carried out to produce and purify a new ACE inhibitor from recombinant E. coli and further elucidate its structure-function relationship. Recombinant pGEX-4T-3 containing ACE inhibitory peptide gene of Saccharomyces cerevisiae was transformed into E. coli BL21(DE3). Glutathione-S transferase (GST) fusion protein from E. Coli BL21(DE3) harboring the recombination pGEX-4T-3 was obtained and the ACE inhibitory peptide was purified with Sephadex G-25 column chromatography. The purified ACE inhibitory peptide was a novel decapeptide with sequence Tyr-Asp-Gly-Gly-Val-Phe -Arg-Val-Tyr-Thr which shows very low similarity to the other ACE inhibitory peptide sequence. The purified ACE inhibitor competitively inhibited ACE.

The composition of lipid class and fatty acid of free lipids(FL) and bound lipids(BL at low temperature and BL at high temperature) from Mungbean (Phaseolus radiatus, L) was investigated with the chromatographic procedures. The contents of neutral lipid (NL), glycol lipids(GL) and phospholipids(PL) in FL were 89.1%, 7.1%, and 3.7%, on the other hand those of BL were $49{\sim}56%,\;28{\sim}29%\;and\;15{\sim}21%$, respectively. The major components of NL fraction were triglycerides, 1,2-diglycerides and esterified sterol in the lipids of FL and BL. Esteryl steryl glycosides and monogalactosyl diglycerides were observed as major GL components of FI and BL. Of the PL in FL and BL, phosphatidyl ethanolamine, diphosphatidyl glycerides and phosphatidyl choline were the major components. The predominent fatty acids of NL, GL and PL were linoleic, palmitic and linolenic acids. There are a little difference between the compositions of BL at low and high temperature extraction.

We present light curves of a short period binary system BL Eridani. The light curves were observed with VRI filters by a 50cm wide field robotic telescope at Siding Spring Observatory (SSO), equipped with a 2K CCD camera, which was developed by Korea Astronomy and Space Science Institute (KASI), and Yonsei University Observatory(YUO). The photometric observations were made on 6 nights by automatic operation mode and remote observation mode at SSO and KASI in Korea, respectively. We obtained new VRI CCD light curves and new 5 times of minima, and analyzed the light corves with the Wilson & Deviney (1971) binary 2005 version and derived the new photometric solutions. The mass ratio q=0.48 in this study shows different value with earlier investigators. According to the model analysis, it is considered that the BL Eri system is currently undergoing contact stage of the two binary components, rather than near-contact stage.

The potent biosynthetic precursors, 24$\alpha$-methylcholesterol and 24$\alpha$-methylcholestanol, and the endogenous brassinosteroids (BRs), castasterone (CS) and 6-deoxocastasterone (6-deoxoCS), were identified from shoots of maize seedlings. In addition, the presence for activities of several enzymes involved in the late C6-oxida-lion pathway from 24$\alpha$-methylcholestanol to CS was demonstrated in the plants. However, activity for brassinolide (BL) synthase which catalyze the conversion of CS to BL, the last step of the late C6-oxidation pathway, was not detected in the enzyme solution obtained from the maize shoots. Together with the fact that BL was not identified from the maize shoots, these results strongly suggested that BRs in the maize shoots are biosynthesized during seedling growth and the active BR in the shoots is not BL but CS.

A breeding programme was initiated by utilizing a robust bivoltine breed CSR$_{18}$ and a polyvoltine breed Cambodge with the main objective of developing robust polyvoltine silkworm breeds/hybrids. At F$_1$ and F$_2$, parthenogenetic development was induced following warm water treatment of eggs at 46$^{\circ}C$ for 18 min followed by two backcrosses with Bl$_{67}$, an evolved polyvoltine breed. The newly developed breed was subjected for hybrid study using eight hybrid combinations in the laboratory at F$_{8}$ generation. F$_1$ hybrids between newly developed breed Bl$_{67}$ (Pg) and promising bivoltine breeds exhibited their superiority by expressing significant hybrid vigour for several economic characters like cocoon yield/10,000 larvae, cocoon weight, cocoon shell weight, cocoon shell ratio and denier. Study on cocoon shape variability revealed that cocoons of all the F$_1$ hybrids except BL$_{67}$ (Pg)${\times}$NB$_4$D$_2$ were found comparatively uniform in shape.pe.
