Objective: To evaluate whether T helper 1 (Th1) immune response is predominant in women with reproductive failures (recurrent spontaneous abortion and recurrent implantation failure) and the activation of T cell is related to Th1 propensity. Methods: Women with a history of recurrent implantation failure or recurrent spontaneous abortion comprise the study group (n=37). Controls are normal fertile women without a history of infertility or pregnancy losses (n=11). Th1/Th2 ratios of interferon (INF)-$\gamma$/interleukin (IL)-10 and tumor necrosis factor (TNF)-$\alpha$/IL-10 expression on $CD3^+/4^+$ cells, CD154, and CD69 expression on T cells are measured by flow cytometric analysis. Results: The ratios of TNF-$\alpha$ to IL-10 expressing on $CD3^+/4^+$ cells (Th1/Th2 cell ratios) are significantly higher in study group ($42.1{\pm}2.3$) as compared with that of controls ($28.7{\pm}2.7$) (p=0.002). The overall trend of CD154 and CD69 expression on T cells are elevated in study group than those of controls. The proportion (%) of $CD3^+/4^+/154^+$ cells ($1.7{\pm}0.5$ vs. $0.3{\pm}0.2$, p=0.038) and the % of $CD3^+/8^+/154^+$ cells ($0.6{\pm}0.2$ vs. $0.1{\pm}0.0$, p=0.024) are significantly higher in study group. The % of $CD3^+/69^+$ cells ($5.6{\pm}1.9$ vs. $1.3{\pm}5.4$, p=0.046) and % of $CD3^+/8^+/69^+$ cells ($4.8{\pm}1.3$ vs. $1.8{\pm}0.2$, p=0.035) among $CD3^+/8^+$ cells are significantly increased in study group. Conclusion: Women with reproductive failures have Th1 propensity with increased T cell activation. These finding means that activated T cell has a harmful effect on early pregnancy and implantation by induction of Th1 immunity.

The potential of encapsulated inuloprebiotics from domestic Jerusalem artichokes (Helianthustuberosus) as natural antibacterial growth promotor for an antibiotic replacement in broiler chickens was presently assessed through assays of growth performance, serum immunoglobulin production and influence on caecal microflora. Two hundred-forty, 1-day-old, male broilers (Ross 308) were randomly allotted to four treatments (T1-T4), with three replicate pens per treatment and 20 chicks per pen. Broiler chicks were fed a basal diet (T1: control) or basal diet plus antibiotics (T2: Chlorotetracycline, 0.10%), 300 ppm of the inuloprebiotics (T3), or 450 ppm of the inuloprebiotics (T4) for 35 days. Body weight, dressing percentage or weight of breast and thigh muscles relative to carcass weight of T3 and T4 broiler chickens was significantly (P<0.05) higher than T1 and T2 broiler chickens. The weight of abdominal fat from T3 and T4 broiler chickens were significantly (P<0.05) lower than that of T1 and T2 chickens. Serum immunoglobulins in the T3 and T4 groups were significantly (P<0.05) elevated compared to the T1 and T2 groups. The weight of immune organs, thymus and Bursa of Fabricius relative to live body weight in the T3 and T4 groups were significantly (P<0.05) higher than the T1 and T2 groups. Bifidobacteria and Lactobacillus, which are beneficial bacteria, were present in greater numbers in the caecum of T3 and T4 birds than T1 and T2 groups, whereas potentially harmful Escherichiacoli and Salmonella were present in lower numbers, with differences being significant (P<0.05). These results suggest that a diet supplemented with 300 ppm of inuloprebiotics has potential as an antibiotic replacement for organic livestock feed supplement intended to improve production of broiler chicken.

This study was conducted to examine the effect of Hwangto, Illite, and any other disease resistant materials as dietary supplements on the growth performance and immunity for growing period with 30 Hanwoo male calves weaned 75days in age. Feeding trial was conducted with 6 treatments(five heads/treatment), which were T1(Control), T2(Control + 2% Hwangto), T3(Control + 2% Illite), T4(Control + 0.04% Oligosacharides), T5(Control + 2% Charcoal powder) and T6(Control + 0.1% Chromium picolinate) for 120 days from three to seven months in age. The results obtained are summarized as follows; During the experimental period, average daily gains were 0.82 to 0.92kg, and were high in the order of T3, T6, T4, T5, T2 and T1. Especially the growth rate of calves for growing period was higher in Illite, chromium-picolinate and oligo- sacharides feeding groups than in any other groups. Average daily intakes and intake ratio to body weight of concentrates for 120days were 3.91 to 4.15kg(average 4.03kg) and 3.10 to 3.31% (average 3.21%), respectively. TDN intakes per kilogram gains were 3.20 to 3.57kg(average 3.35kg) and were smaller in the order of T5, T3, T6, T4, T2 and T1, respectively. Density of IgG in serum of calves measured by the IgG SDID Kit was 10.2 to 11.6mg/$m\ell$, and especially increase rate of IgG for experimental period was high in T3 and T5 by 6.9 and 2.8%, respectively. But incidence of disease was not found to be different by treatments. According to the above results it may be concluded that Illite is a sort of clay minerals increased the growth rate, feed efficiency and immunity of early weaned calves for growing period, but was not in unprocessed Hwangto.

This study was conducted to determine the effect of pH adjustment and the addition of cryoprotectants on the storage properties of chicken breast surimi. Surimi as a control was prepared with Alaska pollack by two times of washing treatment and addition of cryoprotectants(4% sugar, 5% sorbitol and 0.3% polyphosphate). Three types of surimi were manufactured by different cryoprotectant conditions(T1: 5% sorbitol+0.3% polyphosphate, T2: 4% sugar+5% sorbitol+0.3% polyphosphate, T3: 2% salt+4% sugar+5% sorbitol+0.3% polyphosphate) and frozen after adjusting the surimi to pH 11.0. The amino acid and saturated fatty acid composition were significantly higher in the control. EAA(essential amino acid), FAA(amino acid in relation to flavor), SAAA(amino acid in relation to saccarinity) and FRAA (fragrant amino acid) were significantly higher in the control. The TBARS(thiobarbituric acid reactive substances) and VBN(volatile basic nitrogen) were increased with storage times. TBARS and VBN values were significantly higher in the control and T3 than the other treatments. The VBN was significantly higher in control and T3 than other surimi samples. Chicken breast surimi adjusted to pH 11.0 had higher in microorganisms than the control, and T1 sample had the highest total plate count. Sensory evaluations were significantly higher in the control and T3 than the other samples. Especially, the overall acceptability of T3 was similar to the control.

The aim of this study was to evaluate Magnetic Resonance Imaging safety by measuring the translational attraction, torque and susceptibility artifact for Bone-Anchored Hearing Aid (BAHA) implant at 1.5 T and 3.0 T MRI by standard criteria. In vitro assessment tools were made of acrylic-resin by American Society for Testing and Materials (ASTM) F2052-06 and F2119-07 standard. Translational attraction of BAHA implant was measured by the maximum deflection angle at 96 cm position, where the magnetically induced deflection was the greatest. The torque was assessed by the qualitative criteria of evaluating the alignment and rotation pattern, when the BAHA implant was positioned on a line with $45^{\circ}$ intervals inside the circular container in the center of the bore. The susceptibility artifact images were obtained using the hanged test tool, which was filled with $CuSO_4$ solution. And then the artifact size was measured using Susceptibility A rtifact Measurement (SA M) software. In results, the translational attraction was 0 mm at both 1.5 T and 3.0 T and the torque was 0(no torque) at 1.5 T, and +1(mild torque) at 3.0 T. The size of susceptibility artifacts was between 13.20 mm and 38.91 mm. Therefore, The BAHA implant was safe for the patient in clinical MR environment.

The mitotic cycle duration and component plase periods of rice (Oryza sativa L. 'Sumjinbyeo and Seokwangbyeo') root merisem cells at 15, 20, and 30$^{\circ}C$ were determined the use of tritiated thymidine, In this work, the time interval between the maxima of sequential mitotic appearances of marked cells was used to estimate the mitotic cycle duration (MCD) of rice, The MCD of rice of the cultivar 'Sumjinbyeo' and 'Seokwangbyeo' at 20. and 30$^{\circ}C$ was 12. and 20hr, respectively. But the MCD of 'Sumjinbyeo' and 'Seokwangbyeo' was 18 and 20hr, at 15$^{\circ}C$. respectively. The MCD decreased with increasing temperature, The duration of component phase of rice cultivar 'Seokwangbyeo' were essentially the same ratio at 20$^{\circ}C$ and 30$^{\circ}C$. but in 'Sumjinbyeo' cultivar the ratio of $G_1$ period was almost doubled while those of $G_2$ and M were decreased by almost two times at 20$^{\circ}C$ and 30$^{\circ}C$. Deoxyribonucleic acid (DNA). Ribonucleic acid (RNA), and protein synthesis were reduced with increasing temperature from 15$^{\circ}C$ to 30$^{\circ}C$ while the MCD was decreased, This result suggest that DNA, RNA and protein synthesis may not affect the MCD from 15$^{\circ}C$ to 30$^{\circ}C$ in rice.

Kidney bean was used in the brewing of Takju. The Takju formed varied the percentage of kidney bean used; that is, 0%(only rice) in $T_{-1}$, 100%(only kidney bean) in $T_{-2}$, 90% in $T_{-3}$, 80% in $T_{-4}$, 70% in $T_{-5}$, 60% in $T_{-6}$, and 50% in $T_{-7}$. We determined the total sugar, pH, reducing sugar, alcohol production, acidity, and DPPH free radical scavenging activity of Takju. The acidic value of $T_{-1}$ was above that of $T_{-6}$, and the pH of $T_{-2}$ was above that of $T_{-1}$. Both satisfy the food code parameters (namely, below 0.5 in acidity, 3.8~4.7 in pH). The alcohol production of $T_{-1}$ was above that of $T_{-2}$. For 2 days of fermentation, the reducing sugar of $T_{-1}$ totaled 2, down from 4.96%. After fermentation, there was not much difference from 4 to 12 days. The antioxidative effect of $T_{-1}$ proved to be much better than those of the other. Thus, we can be seen that these results thus indicate that the role of kidney bean added to Takju show good antioxidative activity. From the result of sensory test, we also concluded that the taste of Takju kidney bean is very similar to that of Takju with rice.

This study was carried out to investigate the effects of adding lotus root and leaf powder on the quality characteristics of cooked pork patties. The patties were of four types: unadulterated (control, T0), 0.5% lotus root powder (T1), 0.25% lotus root and 0.25% lotus leaf powder (T2), and 0.5% lotus leaf powder (T3). We found that the moisture content was highest in T1 group, and that the protein and fat contents were lowest in T1 (p<0.05). The ash content was lowest in T0 (p<0.05). The cooking yield and moisture retention level were not significantly different among the samples, but fat retention was the highest in T3 (p<0.05). The hardness, springiness, cohesiveness and chewiness were also highest in T3, and the gumminess was lowest in T0 (p<0.05). The $L^*$ values tended to increase with longer storage periods, and that of T0 was the highest after nine days of the storage (p<0.05). By contrast, the $a^*$ values decreased with longer storage periods (p<0.05), with that of T3 being the lowest (p<0.05) during storage periods. The water holding capacity decreased with longer storage periods, and that of T1 was the highest (p<0.05) during storage periods. The pH of T1 decreased, and those of T2 and T3 increased with a longer storage period (p<0.05). TBARS values increased with a longer storage period, and those of T0, T1, T2 and T3 were 8.69, 2.95, 0.88 and 0.55 mg/kg, respectively, after nine days of storage (p<0.05).

This study was carried out investigate the effects of the period of dietary supplementation and the level of fermented mineral feed on daily body weight gain and carcass characteristics of Hanwoo steer. The dietary treatments were compared during two supplementation periods (T1:Feeding Hanwoo steers from 18 months to 25 months, T2: feeding Hanwoo steers from 7 months to 25 months), and the diets tested were of four types (0%: normal concentrate as a basal diet, 1%: 1% addition of fermented mineral feed, 2%: 2% addition of fermented mineral feed, and 3%: 3% addition of fermented mineral feed). A Total of 35 Hanwoo steers were allocated into 7 feeding groups. The daily gain of the 0% fermented mineral feed group was lower (0.64 kg) than that of the other groups (1%: 1.08 kg, 2%: 0.90 kg, 3% treatment: 0.75 kg) for the T1 period, and for the T2 period the order was 1% (0.98 kg) > 0% (0.75 kg) > 1% (0.89 kg). The amount of back fat in decreasing order was as follows: 0% (12.0) > 1% (10.8) > 2% (10.2) > 3% fermented mineral feed (7.8 mm) for the T1 period, and for the T2 period the order was C (16 mm) > T1 (13.8 mm) > T3 treatment (12.6 mm). Eye muscle area increased with increased fermented mineral feed levels. The marbling score of the T1 groups was highest with 3% fermented mineral feed (4.2), and of the T2 groups, the highest score was seen with 1% fermented mineral feed (5.6). Meat color and meat maturity were not different among all groups. The grade of meat quantity and meat quality of both the T1 and T2 groups were highest with the addition of 3% fermented mineral feed. The daily income ranged from 2,062 won to 5,265 won in the T1 groups, which were ordered as follows: 1% > 2% > 3% > 0% fermented mineral feed, and of the T2 groups, the 1% group was highest at 6,098 Won, while the 3% group was lowest at 4,590 Won.
