  • Purpose: The objective of this study was to investigate the effects of xyloologosaccharide (XOS)-sugar mixture on glycemic index (GI) and blood glucose in human subjects. Methods: Randomized double-blind cross-over studies were conducted to examine the effect of sucrose with 14% xyloologosaccharide powder (Xylo 14) and sucrose with 20% xylooligosaccharide powder (Xylo 20) on GI and postprandial glucose response at 15, 30, 45, 60, 90, and 120 min. Results: GIs of Xylo 14 and Xylo 20 were $60.0{\pm}23.5$ classified within medium GI range, and $54.3{\pm}17.7$ within low GI range, respectively. Xylo 14 and Xylo 20 showed significantly lower area under the glucose curve (AUC) for 0-15 min (p = 0.0113), 0-30 min (p = 0.0004), 0-45 min (p < 0.0001), 0-60 min (p < 0.0001), 0-90 min (p < 0.0001), and 0-120 min (p = 0.0001). In particular, compared with glucose, the blood glucose levels of Xylo 14 and Xylo 20 were significantly lower at every time point between 15 and 120 min. Conclusion: The results of this study suggested that Xylo 14 and Xylo 20 had an acute suppressive effect on GI and the postprandial glucose surge.

  • Purpose: The purpose of this study was to determine whether there are any differences, with and without a toe spreader (TS), in dynamic foot pressure distribution in children with spastic diplegic cerebral palsy. Methods: Dynamic foot pressure recording using the RSscan system were obtained during walking in 12 participants (male=7, female=5) with and without TS. Mean force was measured for four different plantar regions; great toe, forefoot, midfoot, hindfoot. Displacement of center of pressure (COP), velocity of COP displacement and stance time were also measured during gait. Results: TS walking exhibited statistically significant decrease of mean force under great toe and forefoot (p<0.05), compared with a barefoot walking. Also, TS walking exhibited statistically significant increase of antero-posterior displacement of COP (p>0.05). Conclusion: These findings indicate the potential clinical utility of toe spreader to correct dynamic foot pressure during stance phase in children with spastic diplegic cerebral palsy.

  • Twelve cross bred cows ($300{\pm}20kg$) were fed a basal ration consisting of 1 kg concentrate and untreated or urea treated rice with or without urea-molasses-wheat bran lick block supplementation. The lick blocks were prepared locally using cement as a binding agent. The experiment lasted for 48 days consisting of a preliminary period of 14 days and a measurement period of 34 days. Daily dry ma tter intake (DMI) of straw and lick block, and daily milk yield were recorded during the measurement period. Intake of lick block when fed with untreated straw (US) was significantly higher (p < 0.01) than with urea treated (TS) straw (397 vs 307g $100kg^{-1}$), but lick block supplementation did not significantly affect the in take of US (1.80 vs 1.83kg $100kg^{-1}day^{-1}$) or TS (2.27 vs 2.17kg $100kg^{-1}day^{-1}$). Both urea treatment and lick block supplementation significantly increased (p < 0.01) the milk yield of cows, and the increase due to urea treatment was higher than that due to lick block supplementation. Benefit/cost ratio obtained for feeding US or TS with 1 kg dairy concentrate was similar (5.4), but the marginal return favours TS (5.4:1.0). The benefit/cost ratio for US and TS supplemented with lick block was 3.4 and 3.7. respectively, but the marginal return with US was higher than with TS (1.6:1.0 and 0.9:1.0, respectively).

  • In order to study the inheritance of watermelon seed size, we used six watermelon lines of different seed sizes as parental lines. Six lines include three accessions, 'PI525088' with giant seed (GS), 'Charleston Gray' with big seed (BS), and 'NT' with normal medium size seed (NS), and three near isogenic lines, 'NTss' with small seed (SS), 'NTms' with micro seed (MS) and 'NTts' with tomato seed size (TS) bred by crosses between accession 'NT' of normal seed size and accession 'TDR' of the smallest seed size,. We inspected $F_1$, $F_2$, $BC_1F_1$ (P1), $BC_1F_1$ (P2) populations from the crosses between the adjacent seed size materials like $GS{\times}BS$, $BS{\times}NS$, $NS{\times}SS$, and $MS{\times}TS$, and two crosses between parental lines showing relatively big difference in seed size such as $GS{\times}TS$ and $NS{\times}TS$. Partial single dominant inheritance patterns were observed between $GS{\times}BS$, $NS{\times}SS$, and $MS{\times}TS$ and inheritance patterns based on two genes or more than two genes were speculated between $BS{\times}NS$. A very wide segregation range was observed from the population of $GS{\times}TS$ indicating many quantitative genes involved in the seed sizes. Overall, we speculated that more than six genes are involved in between the biggest and smallest seed size watermelon and three major genes between the normal seed size and the smallest seed size watermelon.

  • Physicochemical properties including viscosity, temperature and pH stability, color turbidity and moisture retention power of xylooligosaccharide(XO) as food material were investigated to apply to food process. The viscosity of 70 bx XO was 930 cP at $20^{\circ}C$ and 90 cP at $60^{\circ}C$, which was higher than that of sugar but lower than that of other oligosacchrides. XO remained stable after heat treatment for 1hr at $100^{\circ}C$ and pH 2.5 to 8.0 indicating excellent heat and pH stability. The pH of XO was measured $5.0{\pm}0.1$ and the color turbidvity of XO was very low at pH $2.5{\sim}4.0$. The color turbidity of XO increased as pH increased, but it was not high enough to affect food process. When heated with 1% glycine the color turbidity of XO was very low and changed little with pH changes. To measure moisture retention power XO was stored at $25^{\circ}C$ and 75% relative humidity for 71 day. XO retained more than 95% of the original weight; whereas sugar lost 28%. These results suggest that XO has useful physicochemical properties for various food process to improve the functionality of food.

  • Background: To explore the expression of TS, RRM, ERCC1, TUBB3 and STMN1 genes in the tissues of patients with non-small cell lung cancer (NSCLC) and its significance in guiding the postoperative adjuvant chemotherapy. Materials and Methods: Real time polymerase chain reaction (PCR) was applied to detect the expression of TS, RRM, ERCC1, TUBB3 and STMN1 genes in the tissues of NSCLC patients so as to analyze the relationship between the expression of each gene and the clinical characteristics and to guide the postoperative individualized chemotherapy according to the detection results of NSCLC patients. Results: Expression of TS gene was evidently higher in patients with adenocarcinoma than those with non-adenocarcinoma (P=0.013) and so was the expression of ERCC1 (P=0.003). The expression of TUBB3 gene was obviously higher in NSCLC patients in phases I/II and IV than those in phase III ($P_1=0.021$; $P_2=0.004$), and it was also markedly higher in patients without lymph node metastasis than those with (P=0.008). The expression of STMN1 gene was apparently higher in patients in phase I/II than those in phase IV (P=0.002). There was no significant difference between the rest gene expression and the clinical characteristics of NSCLC patients (P>0.05). Additionally, the diseasefree survival (DFS) was significantly longer in patients receiving gene detections than those without (P=0.021). Conclusions: The selection of chemotherapeutic protocols based singly on patients' clinical characteristics has certain blindness. However, the detection of tumor-susceptible genes can guide the postoperative adjuvant chemotherapy and prolong the DFS of NSCLC patients.

  • In order to investigate the relation between sewage sludge solubilization and extracellular polymeric substances(EPS) during alkaline-ultrasonic pretreatment, SCOD/TCOD ratio, solubilization rate, VSS/TS ratio, VSS reduction rate, LB-EPS(Loosely-Bound EPS) and TB-EPS(Tightly-Bound EPS) were measured. At the condition of TS 1.0% and pH 12, solubilization rate increased by 27.7%, LB-EPS as Carbohydrate and Protein increased by 14.6 and 13.3 mg/L/g TS, respectively. Withal, VSS decreased by 26.7% and TB-EPS as Carbohydrate and Protein were extracted by 15.7 and 21.9 mg/L/g TS, respectively. Consequently, the concentrations of organic matter and LB-EPS increased and the trends appeared similarly. In addition, the concentrations trend of decreasing solid matter and extracted TB-EPS also appeared similarly.

  • This study was conducted to develop an enzyme-linked immunosorbent assay(ELISA) for the determination of cooked goat meat. Muscle proteins were extracted from goat meat by heating at $98^{\circ}C$ for 15 min. Major thermostable(TS) protein, whose size and pI are 36 and 38 kDa and 4.5 respectively, were purified by DEAE-Sephadex A-50 and Sephadex G-75 column chromatography. The TS protein was immunized into rabbits in order to produce goat specific antibodies. Competitive indirect ELISA(ciELISA) was established by using the anti-TS antibody. The antibody showed high reactivity toward the TS antigen and the boiled goat meat extract but it did not show any reactivities toward extracts of boiled chicken, pork, lamb, and beef. Thus, this ciELISA developed in this study could be applicable to identify goat species from cooked meat.

  • ADAM은 metalloprotease/disintegrin domain을 가진 transmembrane glycoprotein으로서 지금까지 30종류 이상의 ADAM 및 10종류 이상의 ADAM-TS 단백질이 알려져 있다. 이들의 기능은 포유동물의 수정 시 sperm-egg binding과 fusion, myoblast fusion, integrin과의 결합 등에 직접 관여하거나, TNF-alpha 등의 생체신호전달물질이 세포로부터 분비될 때에 이들의 구조를 변화시켜 활성화시키는 효소로서의 작용, 그리고 dendritic cell differentiation 등에 관여하는 것으로 알려져 있다. 본 연구에서는 난소가 제거된 생쥐를 이용하여 자궁조직의 ADAM-8, -9, -10, -12, -15, -17 그리고 -TS1의 gene의 발현이 $17 \beta $-estradiol에 의하여 조절되는 지를 알아보았다. 생후 6 - 8주 된 암컷 생쥐의 난소를 제거하고, 2 주 후에 $17 \beta $-estradiol ($E_2$), progesterone ($P_4$) 혹은 이 둘 혼합액 ($E_2 + P_4$)을 sesame oil에 녹여 근육주사하였다. 2, 6, 12 시간 후 각각 자궁 조직을 얻고 유전자의 발현 양상을 알아보기 위하여 시료로부터 total RNA을 추출하여 역전사 중합효소반응 (RT-PCR)을 실시하였다. Densitometry를 이용, rpL7에 대한 ADAMS의 mRNA 발현 양을 상대적으로 분석하였다. 그 결과 ADAM-8과 -15는 6시간째에서, ADAM-10과 -TS1은 2시간째에서 sesame oil을 주사하거나 $P_4$만을 주사한 군보다 E$_2$를 주사한 군에서 mRNA의 양이 현저하게 증가하였고 ADAM-12는 2시간째에서 ADAM-17은 12시간째에서 sesame oil을 주사하거나 $P_$만을 주사한 군보다 E$_2$를 주사한 군에서 mRNA의 양이 현저하게 증가하였다. 이러한 결과로 미루어 ADAM-8, -10, -15 그리고 TS1은 progesterone에 의하여, ADAM-12와 17은 $17 \beta $-estradiol에 의하여 유전자의 발현이 upregulation 되는 것으로 생각되어진다.

  • Ginseng has been widely used for traditional medicine in eastern Asia and is known to have inhibitory effects on cardiovascular disease (CVD) such as thrombosis, atherosclerosis, and myocardial infarction. Because, platelet is a crucial mediator of CVD, many studies are focusing on inhibitory mechanism of platelet functions. Among platelet activating molecules, thromboxane $A_2$ ($TXA_2$) and P-selectin play a central role in CVD. $TXA_2$ leads to intracellular signaling cascades and P-selectin plays an important role in platelet-neutrophil and platelet-monocyte interactions leading to the inflammatory response. In this study, we investigated the inhibitory mechanisms of total saponin fraction from Korean red ginseng (KRG-TS) on $TXA_2$ production and P-selectin expression. Thrombin-elevated $TXA_2$ production and arachidonic acid release were decreased by KRG-TS dose (25 to $150{\mu}g/mL$)-dependently via down regulation of microsomal cyclooxygenase-1 (COX-1), $TXA_2$ synthase (TXAS) activity and dephosphorylation of cytosolic phospholipase $A_2$ ($cPLA_2$). In addition, KRG-TS suppressed thrombin-activated P-selectin expression, an indicator of granule release via dephosphorylation of mitogen-activated protein kinases (MAPK). Taken together, we revealed that KRG-TS is a beneficial novel compound inhibiting $TXA_2$ production and P-selectin expression, which may prevent platelet aggregation-mediated thrombotic disease.
