The longitudianl study on taurine intake of breast-fed infants from Korean lacto-ovo-vegetarian (n=23) and non-vegetarian(n=22) at 3-5, 15, 30, 60, 90, 120, 150 days postpartum was performed. The taurine content of human milk was analyzed by amino acid autoanalyzer (LKB-Alpha plus) and the human milk intak of infants was measured by test weighing method. The mean taurine content of human milk at each postpartum period was 434$\pm$128.362$\pm$, 304$\pm$90, 306$\pm$90, 302$\pm$77, 310$\pm$108, 248$\pm$53 nmol per ml in non-vegetarian and 418$\pm$112, 380$\pm$97, 314$\pm$97, 262$\pm$83, 206$\pm$79, 176$\pm$55, 153$\pm$31 nmol per ml in lacto-ovo-vegetarian, respectively. The content decreased significantly during lactation(p<0.05). The mean tauring intake at 15, 30, 60, 90, 120, 150 days postpartum was 195$\pm$94, 202$\pm$74, 212$\pm$54, 177$\pm$43, 137$\pm$47, 132$\pm$35, 106$\pm$15 umol per day in infants of lacto-ovo-vegetarian. Thu taurine content in human milk and the taurine intake of infants were different during lactation between non-vegetarian and lacto-ovo-vegetarian, and the intake per kg body weight during lactaion decreased.

The longitudinal changes on human milk volume per day and lactational performance of 23 Korean lacto-ovo-vegetarians(primiparae=11, multiparae=12) from 0.5 to 5 months after parturition have been studied by test weighing method. The human milk volume per day tended to increase during lactation. The mean volume (SD, ml/day) at 0.5, 1, 2, 3, 4, 5 months were 502(102), 692(127), 697(100), 684( 125), 757(52), 703(70), respectively. The overall mean volume was 661$\pm$132ml/day. The peak milk volume during the lactation was observed at most lactating women at the 1st month. The distributions of the individual mean volume during the first 5 months of lactation were found over 750m1(8.7% ), 650-750ml(47.9% ), 550-650m1(2l.7% ), and 450-550ml(2l.7% ) The number of feeding per day was 8.1 ($\pm$1.0) at 0.5 months postpartum, which was consistently decreased. However, the mean volume per feeding was increased from 62($\pm$9.5)ml at 0.5 month to 112($\pm$13.3)ml at 5 months postpartum. The milk volume was correlated with the peak volume. and maternal age. but not with weight before delivery. maternal height and birth weight. No differences of milk volume and lactational performance between facto-ovo-vegetarian and nonvegetarian women were observed. This study suggests that the human milk volume cited in the recommended dietary allowances for Koreitns is over estimated.

본 실험은 육계에서의 Marek's disease(MD) 백신에 대한 안전성과 효용성을 국내에 기 도입된 18일령 계란에서의 백신 접종 방법(In-Ovo vaccination)을 이용하여 평가하고자 실시하였다. 육계에서의 MD 오염율은 nested PCR을 이용하였으며 백신 접종군과 비접종군간의 생산성 차이를 출하 일령, 평균출하체중, 출하율, 사료 효율을 기본으로 하는 생산 지수를 측정하여 비교하였다. 백신에 의한 면역 억제 현상을 파악하기 위하여 접종 농장에서 채취한 혈청에서의 항체 역가수준과 F낭의 무게 변화를 검사하였다. 국내 육계에서의 MD 발생율을 파악하기 위하여 nested PCR을 실시한 결과 조사 대상 농장 중 26.09%가 오염되었으며, 백신 접종 농장과 비접종 농장간의 생산 지수의 차이는 통계학적으로 유의한 차이가 없었다. 그러나 MDV 오염군에서의 MD 백신 접종 농장의 생산 지수가 비접종 농장보다 높아 간접적으로 효과가 있음이 인정되었다. 면역 억제여부를 파악하기 위한 검사에서는 두 그룹 간 B/B ratio 차이는 없었으나 두 계군 모두 출하 시 심한 위축을 보여주어 혈청 검사 성적과 연계하여 볼 때 국내 육계 농장에서의 IBD 감염이 만연되어 있다는 것을 알 수 있었다. 본 연구를 통해서 국내 육계에서의 MDV 오염율이 파악되었으며, In-Ovo 백신 접종에 의한 MD 백신 접종은 안전성에 있어서는 별다른 문제가 없었으나 효능면에 있어서는 MD 야외감염율이 낮고 IBD와 같은 면역 억제 질병의 감염이 만연되어 있어 정확한 평가가 되지 않아 앞으로 후속 연구가 진행되어야 할 것으로 판단되었다.

Influenza viruses cause respiratory diseases in humans and animals with high morbidity and mortality rates. Conventional anti-influenza drugs are reported to exert side effects and newly emerging viral strains tend to develop resistance to these commonly used agents. Fritillaria thunbergii (FT) is traditionally used as an expectorant for controlling airway inflammatory disorders. Here, we evaluated the therapeutic effects of FT extracts against influenza virus type A (H1N1) infection in vitro, in ovo, and in vivo. In the post-treatment assay, FT extracts showed high CC50 (7,500 ㎍/ml), indicating low toxicity, and exerted moderate antiviral effects compared to oseltamivir (SI 50.6 vs. 222) in vitro. Antiviral activity tests in ovo revealed strong inhibitory effects of both FT extract and oseltamivir against H1N1 replication in embryonated eggs. Notably, at a treatment concentration of 150 mg/kg, only half the group administered oseltamivir survived whereas the FT group showed 100% survival, clearly demonstrating the low toxicity of FT extracts. Consistent with these findings, FT-administered mice showed a higher survival rate with lower body weight reduction relative to the oseltamivir group upon treatment 24 h after viral infection. Our collective results suggest that FT extracts exert antiviral effects against influenza H1N1 virus without inducing toxicity in vitro, in ovo or in vivo, thereby supporting the potential utility of FT extract as a novel candidate therapeutic drug or supplement against influenza.

This study aims to analyze the changes in purchasing decisions in conducting transactions using cash and digital payment systems. Cash payment systems are very different from digital payments because they no longer use banks as intermediaries for transactions. The scope of this study is to determine the differences that take place with purchasing decisions using digital payment systems with OVO Indonesia smart applications. By using the paired T-test sample test method and testing the regression class assumptions, it is expected we will document the comparison between cash and digital payment systems as regards changes in consumers' buying interest behavior towards goods. Data is obtained by purposive sampling using special characteristics for smart application users. The results show that digital payments are developing very quickly, but cash payments still dominate due to the unavailability of complete facilities and infrastructure to support digital payment systems other than in cities. This study illustrates that digital payments have not been able to completely change consumer buying behavior in large numbers, but the main finding in this study is an increase in the percentage of digital payment usage to the online market, due to the many conveniences provided in OVO smart applications.

The purpose of this study was to evaluate the relation of nutrients intake and copper status between nonvegetarian female college students and lacto-ovo-vegetarian female college students. The height, weight and serum copper concentrations were determined. Food nutrients analysis procedure was made by computer using food composition table. The results was summarized as followed; 1) Mean values of weight & height were respectively 53.581$\pm$1.68kg.157.051$\pm$1.43cm in nonvegetarians and 51.23$\pm$1.45kg.156.65$\pm$1.24cm in facto-ovo-vegetarians. 2) The average intakes of protein, fat, carbohydrate, fiber, Ca, P, Fe and Vit. C were above the RDA in the two groups, but those of calories was below the RDA in non-vegetarians. Especially, fiber and icon intakes were significant in the two groups(p< 0.01, p< 0.05). 3) The percentage of iron absorption was 7.64% in nonvegetarians and 5% in facto-ovo-vegetarians. 4) Mean serum copper values of nonvegetarian and vegetarian were 107.08$\pm$14.39ug/100m1 and 113.31$\pm$20.86ug/100ml, respectively.

Objective: The effects of vaccinating 18-day-old chicken embryos with the combination of recombinant Eimeria profilin plus Clostridium perfringens (C. perfringens) NetB proteins mixed in the Montanide IMS adjuvant on the chicken immune response to necrotic enteritis (NE) were investigated using an Eimeria maxima (E. maxima)/C. perfringens co-infection NE disease model that we previously developed. Methods: Eighteen-day-old broiler embryos were injected with $100{\mu}L$ of phosphate-buffered saline, profilin, profilin plus necrotic enteritis B-like (NetB), profilin plus NetB/Montanide adjuvant (IMS 106), and profilin plus Net-B/Montanide adjuvant (IMS 101). After post-hatch birds were challenged with our NE experimental disease model, body weights, intestinal lesions, serum antibody levels to NetB, and proinflammatory cytokine and chemokine mRNA levels in intestinal intraepithelial lymphocytes were measured. Results: Chickens in ovo vaccinated with recombinant profilin plus NetB proteins/IMS106 and recombinant profilin plus NetB proteins/IMS101 showed significantly increased body weight gains and reduced gut damages compared with the profilin-only group, respectively. Greater antibody response to NetB toxin were observed in the profilin plus NetB/IMS 106, and profilin plus NetB/IMS 101 groups compared with the other three vaccine/adjuvant groups. Finally, diminished levels of transcripts encoding for proinflammatory cytokines such as lipopolysaccharide-induced tumor necrosis $factor-{\alpha}$ factor, tumor necrosis factor superfamily 15, and interleukin-8 were observed in the intestinal lymphocytes of chickens in ovo injected with profilin plus NetB toxin in combination with IMS 106, and profilin plus NetB toxin in combination with IMS 101 compared with profilin protein alone bird. Conclusion: These results suggest that the Montanide IMS adjuvants potentiate host immunity to experimentally-induced avian NE when administered in ovo in conjunction with the profilin and NetB proteins, and may reduce disease pathology by attenuating the expression of proinflammatory cytokines and chemokines implicated in disease pathogenesis.

The longitudinal changes on contents of calcium, phosphorous and magnesium of breast milk of 23 Korean lacto-ovo-vegetarians(primiparae=11, multiparae=12) at 0.5, 1, 2 and 3 months postpartum have been studied. The mean ash content of breast milk per 100ml was 0.21g in total lactating women(n=23), and it decreased significantly during lactation(p<0.05). The mean calcium, phosphorous and magnesium contents of breast milk per 100ml were 26.83mg, 14.01mg and 2.72mg, respectively. Body calcium and phosphorous contents decreased significantly during lactation(p<0.05), but magnesium content tended to increase during lactation. There were no significant differences in ash, calcium, phosphorous and magnesium contents between primiparae and multiparae. The ratio of calcium to phosphorus was about 1.95:1 in breast milk and 0.62 : 1 in maternal dietary intake. In calcium and phosphorous, no correlation was found between maternal dietary intake and the concentration in breast milk. This study suggests that the contents of calcium, phosphorous and magnesium in lacto-ovo-vegetarian breast milk are not different from the concentrations of those in non-vegetarian.
