  • The effects of resin finish and dyeabilities of four kinds of Iyocell fabrics that were manufactured by four kinds of pulps were investigated. The dyeabilities of Iyocell fabrics were similar, but differed from cotton fabric. In early stage of 30 minutes, cotton fabric was shown higher dye exhaustion ratio than Iyocell fabrics, however after then cotton fabric did not increase dye exhaustion, Iyocell fabrics increased continuously. At last, the dye exhaustion ratio of Iyocell fabrics were about 75% and that of cotton fabric was 65%. Two kinds of experimental procedures were applied for Iyocell fabrics. One was what the fabrics were treated with resins and washed with cellulase, and then dyed with reactive dyes. The other procedure was the fabrics were dyed with reactive dyes, and then applied the resin treatments and cellulase washing. After fibrillation and washing the undyed Iyocell fabric and the Iyocell fabric that was dyed with C.I.Reactive Red 120, their weight loss ratios were 3.5% and 2.8%, respectively. Dyeing with reactive dyes caused the crosslinking between cellulose and dyes and the crosslinking decreased fibrillation. The weight loss by enzyme washing of Iyocell fabrics decreased by the glyoxal and melamine resin treatments. The reduction of weight loss can be caused by fibrillation decrease. Dyeing and resin treating can be showed the synergic effect on the reduction of fibrillation. The effect of glyoxal resin on the reduction of fibrillation was a little better than that of melamine resin.

  • 여러 가지 처리가 난백의 항원성을 감소시키는데 미치는 영향을 조사하기 위하여, 토끼 항난백항체로 난백 처리물들의 간접 경합 ELISA(ciELISA)를 실시하였다. 식물성, 동물성, 미생물성의 9가지 효소를 이용한 가수분해처리는 난백의 항원성에 영향을 주지 못했다. 보다 효율적인 효소 가수분해를 위해 방사선 조사 후, 효소처리를 실시했는데, 이것 역시 항원성을 감소시키지 못했다. Trifluoromethanesulfonic acid 처리는 난백의 항원성을 거의 제거시키는 것으로 나타났다. 열처리는 $121^{\circ}C$ 고온처리의 경우에서만 반응성이 1/10,000이하로 감소하여 항원성이 거의 사라졌다. NaOH 단독 처리는 0.3%(w/v) 이상의 농도에서 반응성이 감소되기 시작하여, 1%(w/v) 이상에서는 반응성이 1/10,000이하로 감소하였다. NaOH 처리에 $70^{\circ}C$, 15분간의 열처리를 더해 주면, NaOH 단독 처리시보다 효과적으로 항원성이 감소되는 것으로 나타났다.

  • Supplementation of serum and estrogen in in vitro maturation(IVM) medium was shown to improve embryo development and quality in several species. This study investigates the effect of ovarian estrus stage on canine oocyte quality and supplementation of medium with canine serum or estrogen on IVM of canine oocytes. As results, in experimental 1, IVM oocytes collected from follicular stage ovaries to MII stages($10.2{\pm}1.5%$) was higher (p<0.05) with 10% canine estrus stage serum than control($1.3{\pm}1.6%$), anoestrus stage serum($4.0{\pm}1.6%$), luteal stage serum($2.7{\pm}1.7%$) and 10% FBS($1.3{\pm}1.6$). In experimental 2, 10% canine estrus stage serum supplementation has highest maturation rate to MII stages($10.0{\pm}1.8%$) and there were significant differences(P<0.05) with another treatment in follicular stages group. In order to investigate the synergic effect of estrous serum and estrogen supplementation, different estrous stage groups of oocytes were cultured with 2 ug/ml estrogen plus various concentrations of different reproductive stage serum and FBS(experimental 3). As results, the rate of maturation to metaphase II(MII) stage was significantly higher(p<0.05) in oocytes from the follicular stage supplemented with estrogen and 10% canine estrus stage serum(11.5%) compared to the other groups(6.0 - 8.8%). The present study was demonstrated that canine serum and the estrus cycle of the bitch affect the meiotic competence of oocytes. Hormonal influences within the follicle may be one of the factors responsible for the greater proportion of maturation of oocyte to MII from bitches at the follicular phase.

  • Objectives : We studied the effects of electro and laser acupuncture treatment with $GB_{39}$ and $GB_{34}$ on neuropathic pain in rats induced by tibial and sural nerve ligation. Methods : To produce the model of neuropathic pain, the tibial and sural nerves of rats were ligated by a 6-0 silk thread. Three days after the neuropathic surgery, only electro acupuncture(EA), electro acupuncture and 830 nm laser acupuncture(EA-LA-1), and electro acupuncture and 904 nm laser acupuncture(EA-LA-2) were treated with $GB_{39}$ and $GB_{34}$ twice a week for 8 weeks. We observed the withdrawal response of neuropathic rats' legs by von Frey filament and acetone stimulation. We also observed c-fos and nocieptin on the central gray area in the midbrain of neuropathic rats. Results : As we observed the effect of mechanical allodynia, the EA and EA-LA-1 groups in 5 and 6 weeks and the EA-LA-2 group in 6 weeks increased significantly compared with the control group. As for the effect of c-fos activity in the central gray region, the EA, EA-LA-1, and EA-LA-2 groups decreased significantly compared with the control group. The EA-LA-2 group increased significantly compared with the control group as regards the effect of nociceptin activity in the central gray region. Conclusions : We noticed the synergic effect of electro and laser acupuncture treatment because the EA-LA-1 and EA-LA-2 groups had more controllable effect compared with the control group. This study can be used in clinical therapy for neuropathic pain.

  • A series of Zr,S co-doped $TiO_2$ were synthesized by a modified sol-gel method and characterized by various spectroscopic and analytical techniques. The presence of sulfur caused a red-shift in the absorption band of $TiO_2$. Co-doping of sulfur and zirconium (Zr-$TiO_2$-S) improves the surface properties such as surface area, pore volume, and pore diameter and also enhances the thermal stability of the anatase phase. The Zr-$TiO_2$-S systems are very effective visible-light active catalysts for the degradation of toluene. All reactions follow pseudo firstorder kinetics with the decomposition rate reaching as high as 77% within 4 h. The catalytic activity decreases in the following order: Zr-$TiO_2$-S >$TiO_2$-S >Zr-$TiO_2$>$TiO_2$$\approx$ P-25, demonstrating the synergic effect of codoping with zirconium and sulfur. When the comparison is made within the series of Zr-$TiO_2$-S, the catalytic performance is found to be a function of Zr-contents as follows: 3 wt % Zr-TiO2-S >0.5 wt % Zr-$TiO_2$-S> 5 wt % Zr-$TiO_2$-S >1 wt % Zr-$TiO_2$-S. Higher calcination temperature decreases the reactivity of Zr-$TiO_2$-S.

  • Objective: The purpose of this study is to report the case of a patient with recurring non-small cell lung carcinoma (NSCLC) taking Samchilchoongcho-Jung with Afatinib. Methods: An NSCLC patient diagnosed with multiple bone and pulmonary metastasis was taking Afatinib (20 mg/day) and suffering from stomatitis caused by the Afatinib. The patient was treated with Samchilchoongcho-Jung (1,500 mg/ day) for 3 months. The tumor size was measured with computed tomography, and laboratory findings, including tumor markers (CEA, Cyfra 21-1), were also followed up. Stomatitis was measured by a numeric rating scale, and adverse events were evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 4.0. Results: After combined treatment, stable disease was shown on computed tomography. The tumor marker levels of CEA and Cyfra 21-1 were decreased, and the stomatitis significantly improved. NCI-CTCAE 4.0 showed no adverse events. Conclusion: This case study suggests that Samchilchoongcho-Jung may have a synergic effect, in conjunction with Afatinib, on the treatment of patients with recurring NSCLC.

  • The purposes of this study were to identify the significance of a nutrition teacher, to analyze the importance of competence as a nutrition teacher and to evaluate the importance and difficulty for duties of nutrition teachers. The questionnaire was distributed to 554 preliminary teachers and a total of 468 usable data were collected with 84.5% of response rate from August to October 2006. The statistical data analysis was completed by using SPSS Win (ver. 10.0) for descriptive analysis, t-test, ANOVA and ${\chi}^2-test$. The results were as follows: Preliminary nutrition teachers expected that conversion of a school dietitian into a nutrition teacher could lead to systematic and constant nutrition education and come into synergic effect by doing meal service with nutrition education. For a teacher's competence, all three paradigms were perceived as important. It was evaluated to be high for a knowledge factor in the empirical analytic paradigm, a personality factor in the practical interpretive paradigm and an attitude factor in the critical emancipatory paradigm. And 'a knowledge for nutrition and sanitation (4.59)' and 'an ability to raise a self-management capacity for right food habit and dietary life (4.59)' were showed as most important in a nutrition teacher. It appeared that both important and difficult duties of nutrition teachers were nutrition education, nutrition counseling and sanitation quality of nutrition education; the most necessary solution was to develop a reference and program for nutrition education (37.4%). In conclusion, the systematic supports of district offices of education and associated institutions as well as sustained efforts of preliminary nutrition teachers for themselves should lead to establish a successful system of nutrition teachers.
