To elucidate the effect of soy isoflavone supplementation and exercise on serum lipids in normolipidemic and mildly hyperlipidemic postmenopausal period, 54 women residing in Seoul area were recruited. The subjects were divided into 4 groups: control group (n=13), isoflavone group (n=14), exercise group (n=14), isoflavone + exercise group (n=13). The control group was given placebo capsules, isoflavone group was given soy isoflavone supplements (90 mg/day), exercise group was given placebo capsules and exercised 3 times/week, over 30 min/time, and isoflavone + exercise group took soy isoflavone supplement and exercised. The duration of study were 8 weeks. The average age of the subjects was 57.0 years, 56.0 years, 54.4 years, and 55.2 years, respectively. There were no significant differences among the four groups in terms of height, weight, and body mass index. There were no significant differences among the four groups in terms of serum, total cholesterol, HDL-cholesterol. But the subjects indicated a significant difference in serum LDL-cholesterol (110.5 mg/day in before versus 74.6 mg/day in after) in the isoflavone + exercise group at the levels of p<0.05. In conclusion, the isoflavone supplementation and exercise may be helpful to decrease serum lipids of normolipidemic and mildly hyperlipidemic postmenopausal women.

1. Objectives: Three herbal formulas (Yuldahanso-tang, Chungsimyonja-tang, and Taeeumjowi-tang) for Taeeumin were applied to investigate the immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses in murine macrophage cell line (RAW 264.7) and ovalbumin (OVA)-immunized mice. 2. Methods: This study was carried out in nitric oxide (NO) synthesis in RAW 264.7 cells and cellular proliferation in mouse splenocytes according to three herbal formulas. C57BL/6 mice were immunized intraperitonially with OVA/aluminium ($100\;{\mu}g/200\;{\mu}g$/mouse) on day 1, 8, and 15. Three herbal formulas were administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes) in plasma were measured. 3. Results: Yuldahanso-tang and Chungsimyonja-tang increased NO synthesis in RAW 264.7 cells. Three herbal formulas significantly enhanced cellular proliferation by LPS and Con A in splenocytes from OVA-immunized mice (p<.001). Three herbal formulas for Taeeumin also significantly enhanced plasma OVA-specific IgG, IgG1, and total IgM levels compared with the OVA/Alum group. 4. Conclusion: These results suggested that three herbal formulas for Taeeumin could be used as stimulator of immune response.

Using Streptomyces sp. YU100 isolated from Korean soil, the fermentative production of phospholipase D was attempted along with its purification and characterization studies. When different carbon and nitrogen sources were supplemented in the culture medium, glucose and yeast extract were found to be the best. By varying the concentration of nutrients and calcium carbonate, the optimal culture medium was determined as 2.0% glucose, 1.5% yeast extract, 0.5% tryptone 0.3% calcium carbonate. During cultivation, the strain secreted most of the phospholipase D in the early stage of growth within 24 h. The phospholipase D produced in the culture broth exhibited hydrolytic activity as well as transphosphatidylation activity on lecithin (phosphatidylcholine). In particular, the culture broth showed 8.7 units/ml of hydrolytic activity when cultivated at $28^{\circ}C$ for 1.5 days. The phospholipase D was purified using 80% ammonium sulfate precipitation and DEAE-Sepharose CL-6B column chromatography, which produced a major band of 57 kDa on a 10% SDS-polyacrylamide gel with purity higher than 80%. The enzyme showed an optimal pH of 7 in hydrolytic reaction, and at pH 4 in a transphosphatidylation reaction. The enzyme activity increased until the reaction temperature was elevated to $60^{\circ}C$. The enzyme was relatively stable at high temperatures and neutral pH, but significantly unstable in the alkaline range. Among the detergents tested as emulsifiers of phospholipids, the highest enzyme activity was observed when 1.5% Triton X-100 was employed. However, no inhibitory effect by metal ions was detected. Under optimized reaction conditions, the purified enzyme not only completely decomposed PC to phosphatidic acid within 1 h, but also exhibited higher than 80% conversion rate of PC to PS by transphosphatidylation within 4 h.

Bactericidal/permeability-increasing protein (BPI) and lipopolysaccharide-binding protein (LBP) are important components of the mammalian innate defence system against Gram-negative infections. The BPI/LBP cDNA was identified from the black rockfish ConA/PMA or LPS stimulated leukocyte cDNA library. The full-length BR-BPI/LBP cDNA was 2118 bp long and contained an open reading frame (ORF) of 1422 bp that encoded 473 amino-acid residues. The 5' UTR had a length of 57 bp, and the 3' UTR 639 bp. The molecular weight and theoretical isoelectric point (pI) values were calculated 51.4 kDa and 9.72, respectively. Compared with other known BPI or BPI/LBP peptide sequences, the most conserved regions of the black rockfish BPI/LBP peptide were found to be the BPI1 N-terminal, BPI2 C-terminal domains and a LPS binding domain. Phylogenetic analysis based on the deduced amino acid sequence revealed a homologous relationship between the BPI/LBP sequence of black rockfish and that of other teleosts. The black rockfish BPI/LBP gene was predominantly expressed in the PBLs, head kidney, trunk kidney and spleen. The expression of the black rockfish BPI/LBP molecule was induced in the peripheral blood leukocytes (PBLs) from 1 to 24 h following LPS stimulation, with a peak at 12 h post-stimulation.

[ ${\alpha}$ ]Galactosidase was purified from a culture filtrate of Mortierella sp. by CM-sephadex C-50, and subsequent Sephadex G-100 column chromatography. The final preparation thus obtained showed a single band on SDS-polyacrylamide gel electrophoresis. The molecular weight was determined to be 56 kDa. $Gal^3Man^4$ ($6^3$-mono-O-${\alpha}$-D-galactopyranosyl-4-O-${\beta}$-D-mannotetraose), $Gal^{2,3}Man_5$ ($6^{2,3}$-di-O-${\alpha}$-D-galactopyranosyl-4-O-${\beta}$-D-mannopentaose), $Gal_2Man_3$ ($6^2$-mono-O-${\alpha}$-D-galactopyranosyl-4-O-${\beta}$-D-mannotriose), $Gal^2Man_6$ ($6^2$-mono-O-${\alpha}$-D-galactopyranosyl-4-O-${\beta}$-D-mannohexaose) and $Gal^2Man_5$ ($6^2$-mono-O-${\alpha}$-D-galactopyranosyl-4-O-${\beta}$-D-mannopentaose), prepared from 3 types of microbial ${\beta}$-mannnanase, were used as substrates. $Gal^3Man_4$ and $Gal^2Man_3$ had a stubbed ${\alpha}$-galactosyl residue on the $2^{nd}$ and $3^{rd}$ mannose from the reducing end of mannotetraose and mannotriose, thus ${\alpha}$-galactosidase showed a preference for stubbed ${\alpha}$-galactosyl residue. ${\alpha}$-Galactosidase hydrolyzed $Gal^3Man_4$ more rapidly than $Gal^2Man_3$. However, ${\alpha}$-galactosidase hardly acted on $Gal^{2,3}Man_5$, $Gal^2Man_6$ or $Gal^2Man_5$. The enzyme hydrolyzed melibiose to galactose and glucose, raffinose to galactose and sucrose, and also stachyose to galactose and raffinose.

Secondary diseases that occur during the rehabilitation of breast cancer survivors are factors that can negatively change the physical and psychological state of the patient. The rehabilitation after treatment of breast cancer survivors is an important process to prevent cancer recurrence and increase the survival rate because a negative psychological state significantly impacts the long-term survival rate. This study identifies user requirements for the development of functional bras for mastectomy patients in Korea. Participants included 133 patients with one or more breasts removed due to breast cancer and an average age of 53.2 years (53.21 ± 7.57 years, minimum 33 years, maximum 69 years). Women in their 50s had the highest participation rate of 48.9%. Most maintained the same bra size before surgery; however, some experienced changes in bra size because they are not irritated by wounds caused by surgery. Therefore, it is important to pay attention to material when designing a functional bra because it can irritate the surgical site. Only about 41.4% of bras were worn by breast cancer patients because of price burden and lack of education, not complaints related to clothing design and wearability or body shape. Most purchases at hospitals or medical institutions require consultation with a specialist who provides information about a bra mainly at the hospital. The most important considerations when buying a breast cancer bra were size, fit and shape stability.

A gene corresponding to 4-${\alpha}$-glucanotransferase (${\alpha}GTase$) was cloned from the thermophilic bacterium Thermus brockianus. The nucleotide sequence analysis showed that the ${\alpha}GTase$ gene is composed of 1,503 nucleotides and encodes a polypeptide that is 500 amino acids long with a calculated molecular mass of 57,221 Da. The deduced amino acid sequences of Thermus brockianus ${\alpha}GTase$ (TBGT) exhibited a high level of similarity to the amino acid sequence of ${\alpha}GTase$ of Thermus thermophilus (86%), but low level of homology to that of E. coli (26%). The TBGT gene was overexpressed in E. coli BL21, and the corresponding recombinant enzyme was efficiently purified by Ni-NTA affinity chromatography. The enzymatic characteristics revealed that optimal pH and temperature were pH 6 and $70^{\circ}C$, respectively. Most interestingly, TBGT reacted with small oligosaccharides, especially maltotriose, to form various maltooligosaccharides by using its disproportionation activity.

Objectives: This study investigated the effects of Choweseuncheung-tang (CWSCT, Tiaoweishengqing-tang) on body weight, serum lipid level, serum insulin level and serum leptin level in high-fat-diet-induced obese mice. Methods: Four-week-old male C57BL/6 mice were randomly divided into three groups (7 mice in each group), including a normal group, control group, and CWSCT group. The normal group was fed a general diet, but the other groups were fed a high fat diet. The CWSCT group was administered CWSCT for 4 weeks. Animals were weighted weekly and blood lipids, insulin and leptin levels were measured after 4 weeks. Results: The results were as follows. 1. In the CWSCT group, compared with the control, body weight gain was significantly inhibited. 2. In the CWSCT group, compared with the control, the level of HDL cholesterol in serum increased significantly. 3. In the CWSCT group, compared with the control, the ratio of total cholesterol to HDL cholesterol decreased significantly. 4. In the CWSCT group, compared with the control, the elevation of serum leptin level was significantly inhibited. Conclusions: Choweseuncheung-tang treatment has inhibitory effects on obesity and hyperlipidemia in high-fat-dietinduced obese mice.

Objectives: Three yin-tonifying formulae (Ssanghwa-tang, Yukmijihwang-tang and Jaeumganghwa-tang) were applied to investigate their immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses in the murine macrophage cell line (RAW 264.7) and in ovalbumin (OVA)-immunized mice. Methods: This study was carried out in nitricoxide (NO) synthesis in RAW 264.7 cells and cellular proliferation in mouse splenocytes in association with three herbal formulas. C57BL/6 mice were immunized intraperitoneally with OVA/aluminum ($100\;{\mu}g/200\;{\mu}g$/mouse) on days 1, 8, and 15. Three herbal formulas were administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes) in plasma were measured. Results: All three yin-tonifying formulas significantly enhanced cellular proliferation by LPS and Con A in splenocytes from OVA-immunized mice (p<0.001). Also, these herbal formulas all significantly enhanced plasma OVA-specific IgG, IgG1, and total IgM levels compared with the OVA/Alum group. Conclusion: These results suggested that the three yin-tonifying formulae could be used as stimulators of immune response.
