The quality characteristics of baguette bread added with water extracts of Liriopis tuber(LT) and effect of the diets containing 20% dried and powered baguette with 10% LT on the level of blood sugar and lipids in the diabetes induced rat by streptozotocin were investigated. pH of the dough added with 5∼10% LT was 5.00∼5.03 which were lower than that of control(5.12). The volume of the dough with 10% LT after 2nd fermentation was the biggest. Loaf volume index of the bread with 10% LT was significantly higher than that of control. $L^{*}$ values of outside and inside of the baguette decreased in proportion to the increase of the LT, while the $a^{*}$ values increased. Color of the bread with LT showed light dark-red. There was no significant difference in hardness, but springiness and gumminess were higher in the bread with 10% LT. Sweet taste increased, color acceptability and overall taste were enhanced by addition of LT, but it did not affect the sour and astringent taste. The overeating phenomenon showed in the diabetes rat decreased in the group fed with baguette bread with LT, while feed efficiency increased by feeding of the bread with LT. The level of glucose, neutral lipid and total cholesterol in blood were 118.92,95.47 and 37.42mg/dL in the control group, 245.60, 121.54 and 102.43 mg/dL in the diabetes control, 148.40, 103.25 and 57.63 mg/dL in the baguette diet group, respectively. There was no significant difference of HTR between control group and baguette diet group, while atherogenic index was considerably decreased, which might represent improving and preventing effects of diabetes.s.s.

Trophoblasts, in the placenta, play a role for placental development as well as implantation in the early pregnancy. The characteristics and functions of trophoblast are identified by their localization and potency for proliferation, differentiation, and invasion. Thus, inadequate trophoblast cell death induces trophoblast dysfunction resulting in abnormal placental development and several gynecological diseases. Recently, it was reported that increased immortalization-upregulated protein-2 (IMUP-2) by hypoxia influences trophoblast apoptosis. However, IMUP-2 function on autophagy, which is type II programmed cell death remains unclear. In this study, we analyzed IMUP-2 expression in trophoblast cells (HTR8-SVneo) and compared IMUP-2 effects on cell death including apoptosis and autophagy in trophoblast regardless of IMUP-2 expression. Increased IMUP-2 in trophoblast by IMUP-2 gene transfection induces cell death, especially, apoptosis increases more than autophagy (p<0.05). However, the decreased IMUP-2 in trophoblasts after siRNA treatment decreased apoptosis with the decreased activities of caspase 3 and 7. The expressions of LC3 and MDC as an autophagosome makers and phosphorylated mTOR, which is a negative regulator for autophagy, increased. In addition, the S phase of cell cycle increased in trophoblasts when IMUP-2 expression decreased. Taken together, the alteration of IMUP-2 can control the balance between apoptosis and autophagy of trophoblasts resulting in functional involvement in placental development and in gynecological diseases by regulating the function of trophoblasts.

To investigate the effects of electro-acupuncture (EA) treatment on regions remote from the application, we measured cellular, enzymatic, and transcriptional activities in various internal tissues of healthy rats. The EA was applied to the well-identified acupoint ST36 of the leg. After application, we measured the activity of natural killer cells in the spleen, gene expression in the hypothalamus, and the activities of antioxidative enzymes in the hypothalamus, liver and red blood cells. The EA treatment increased natural killer cell activity in the spleen by approximately 44%. It also induced genes related to pain, including 5-Hydroxytryptamine (serotonin) receptor 3a (Htr3a) and Endothelin receptor type B (Ednrb) in the hypothalamus, and increased the activity of superoxide dismutase in the hypothalamus, liver, and red blood cells. These findings indicate that EA mediates its effects through changes in cellular activity, gene expression, and enzymatic activity in multiple remote tissues. The sum of these alterations may explain the beneficial effects of EA.

BACKGROUND/OBJECTIVES: We investigated the effects of a combination of grape pomace (Vitis labrusca, Campbell Early) and Omija fruit (Schizandra chinensis, Baillon) ethanol extracts on lipid metabolism and antioxidant defense system in diet-induced obese mice. MATERIALS/METHODS: Forty male C57BL/6J mice were divided into four groups and fed high-fat diet (control group, CON) or high-fat diet added 0.5% grape pomace extract (GPE), 0.05% Omija fruit extract (OFE) or 0.5% GPE plus 0.05% OFE (GPE+OFE) for 12 weeks. RESULTS: In contrast to the GPE- or OFE-supplemented groups, the GPE+OFE group showed significantly lower body weight and white adipose tissue weights than the CON group. Moreover, GPE+OFE supplementation significantly decreased plasma total cholesterol and increased the plasma HDL-cholesterol/total-cholesterol ratio (HTR) compared to the control diet. The hepatic triglyceride level was significantly lower in the GPE+OFE and GPE groups by increasing ${\beta}$-oxidation and decreasing lipogenic enzyme compared to the CON group. Furthermore, GPE+OFE supplementation significantly increased antioxidant enzyme activities with a simultaneous decrease in liver $H_2O_2$ content compared to the control diet. CONCLUSIONS: Together our results suggest that supplementation with the GPE+OFE mixture may be more effective in improving adiposity, lipid metabolism and oxidative stress in high-fat diet-fed mice than those with GPE and OFE alone.

Mycobacterium tuberculosis is capable of growing and survival within macrophage. The purpose of this study was to identify the genes regulated by infection of mycobacteria in human monocytic THP-1 cells. We used the differential display reverse transcriptase polymerase chain reaction (DD RT-PCR) and nothern blot analysis to confirm the differentially expressed genes from THP-1 cells infected with live Mycobacterium tuberculosis H37Rv, heat-killed Mycobacterium tuberculosis H37Rv and live Mycobacterium bovis BCG. Among many up or down-regulated clones, 27 clones were sequenced and compared with known genes on GenBank. Thirteen of over-expressed clones from THP-1 cells infected with live Mycobacterium tuberculosis H37Rv were identical to human prothymosin alpha, eight were novel clones and six clones showed homology with Human ferritin H chain, Esherichia coli bgl, Mouse RNA-dependent EIF-2 alpha kinase, E. coli htrL, Hyaluronan receptor and T cell receptor. Our result suggests that Mycobacterium tuberculosis might regulate prothymosin alpha gene transcription in monocytic THP-1 cell.
