This study analyzed the factors influencing the purchase of protein foods from the perspective of a healthy diet. In the first study, the relationship between consumers consciousness of healthy eating and purchasing meat products was investigated through regression analysis using data from consumer panels agri-food purchase receipts. The frequency of purchasing meat products in four categories was used for the study. The results of the study show the impact of consumers consciousness of healthy eating on the frequency of purchasing bacon, sausage, and chicken breast. As the level of consumers consciousness of healthy eating increased, the frequency of purchasing bacon and sausage was lower, whereas that of chicken breast was higher. The purpose of the second study was to identify the factors influencing the intention to purchase protein supplements using stepwise regression analysis. Four hundred respondents participated in the online survey, and the experiments were designed as between-subjects method. The results show that the formulation of protein supplements, lifestyle, physical activity, and health consciousness have a significant influence on purchase intention. In particular, the interaction effects of message framing with formulation and health consciousness show a significant effect on purchase intention. The implications of this study and suggestions for future research are included in the last chapter of each study.์†Œ๋น„์ž๋“ค์˜ ๊ฑด๊ฐ•์— ๋Œ€ํ•œ ๊ด€์‹ฌ์ด ์ปค์ง€๋ฉด์„œ ๋‹จ๋ฐฑ์งˆ ์‹ํ’ˆ์— ๋Œ€ํ•œ ๊ด€์‹ฌ๋„ ๊ธ‰์ฆํ•˜์˜€๋‹ค. ๋ณธ ์—ฐ๊ตฌ๋Š” ๋‹จ๋ฐฑ์งˆ ์‹ํ’ˆ์˜ ๊ตฌ๋งค์— ์˜ํ–ฅ์„ ๋ฏธ์น˜๋Š” ์š”์ธ๋“ค์— ๋Œ€ํ•œ ๋ถ„์„์„ ๊ฑด๊ฐ•ํ•œ ์‹๋‹จ ๊ด€์ ์—์„œ ๋ถ„์„ํ•˜์˜€๋‹ค. ์ฒซ๋ฒˆ์งธ ์—ฐ๊ตฌ์—์„œ๋Š” ์†Œ๋น„์ž ํŒจ๋„๋“ค์˜ ๋†์‹ํ’ˆ ๊ตฌ๋งค ์˜์ˆ˜์ฆ ๋ฐ์ดํ„ฐ๋ฅผ ํ™œ์šฉํ•˜์—ฌ ํšŒ๊ท€๋ถ„์„์„ ํ†ตํ•ด ๊ฑด๊ฐ•ํ•œ ์‹๋‹จ์— ๋Œ€ํ•œ ์†Œ๋น„์ž ์ธ์‹๋„์™€ ์ถ•์‚ฐ๋ฌผ ๊ตฌ๋งค ๊ฐ„์˜ ๊ด€๊ณ„๋ฅผ ์กฐ์‚ฌํ–ˆ๋‹ค. ์—ฐ๊ตฌ๋ฅผ ์ˆ˜ํ–‰ํ•˜๊ธฐ ์œ„ํ•ด 4๊ฐœ์˜ ๋ฒ”์ฃผ์— ์†ํ•œ ์ถ•์‚ฐ๋ฌผ ์ œํ’ˆ๋“ค์˜ ์†Œ๋น„์ž ๊ตฌ๋งค ํšŸ์ˆ˜๋ฅผ ์‚ฌ์šฉํ•˜์˜€๋‹ค. ์—ฐ๊ตฌ ๊ฒฐ๊ณผ, ์†Œ๋น„์ž๋“ค์˜ ๊ฑด๊ฐ•ํ•œ ์‹๋‹จ์— ๋Œ€ํ•œ ์˜์‹๋„๊ฐ€ ๋ฒ ์ด์ปจ, ์†Œ์‹œ์ง€, ๊ทธ๋ฆฌ๊ณ  ๋‹ญ๊ฐ€์Šด์‚ด์˜ ๊ตฌ๋งค ํšŸ์ˆ˜์— ์˜ํ–ฅ์„ ๋ฏธ์ณค๋‹ค. ์˜์‹ ์ˆ˜์ค€์ด ๋†’์„์ˆ˜๋ก ๋ฒ ์ด์ปจ, ์†Œ์‹œ์ง€ ๊ตฌ๋งค ํšŸ์ˆ˜๋Š” ๊ฐ์†Œํ•˜์˜€์œผ๋ฉฐ, ๋ฐ˜๋Œ€๋กœ ์˜์‹ ์ˆ˜์ค€์ด ๋†’์„์ˆ˜๋ก ๋‹ญ๊ฐ€์Šด์‚ด ๊ตฌ๋งค ํšŸ์ˆ˜๋Š” ์ฆ๊ฐ€ํ•˜์˜€๋‹ค. ๋‘๋ฒˆ์งธ ์—ฐ๊ตฌ์—์„œ๋Š” ๋‹จ๊ณ„์  ํšŒ๊ท€๋ถ„์„์„ ์‚ฌ์šฉํ•˜์—ฌ ๋‹จ๋ฐฑ์งˆ ๋ณด์ถฉ์ œ ๊ตฌ๋งค ์˜๋„์— ์˜ํ–ฅ์„ ๋ฏธ์นœ ๋ณ€์ˆ˜๋“ค์„ ์กฐ์‚ฌํ–ˆ๋‹ค. ๋ณธ ์—ฐ๊ตฌ๋ฅผ ์œ„ํ•ด 400๋ช…์˜ ์ฐธ๊ฐ€์ž๋“ค์„ ๋Œ€์ƒ์œผ๋กœ ์˜จ๋ผ์ธ ์„ค๋ฌธ์กฐ์‚ฌ๋ฅผ ์ˆ˜ํ–‰ํ•˜์˜€์œผ๋ฉฐ, ํ”ผํ—˜์ž๊ฐ„ ์„ค๊ณ„ ๋ฐฉ์‹์„ ํ†ตํ•ด ์‹คํ—˜์„ ์„ค๊ณ„ํ•˜์˜€๋‹ค. ๊ทธ ๊ฒฐ๊ณผ ๋‹จ๋ฐฑ์งˆ ๋ณด์ถฉ์ œ์˜ ์ œํ˜•, ๋ผ์ดํ”„ ์Šคํƒ€์ผ, ์‹ ์ฒด ํ™œ๋™, ๊ฑด๊ฐ• ์˜์‹๋„๊ฐ€ ๊ตฌ๋งค ์˜๋„์— ์œ ์˜๋ฏธํ•œ ์˜ํ–ฅ์„ ๋ฏธ์ณค๋‹ค. ํŠนํžˆ ๋ฉ”์‹œ์ง€ ํ”„๋ ˆ์ด๋ฐ์˜ ์ œํ˜•๊ณผ ๊ฑด๊ฐ• ์ธ์‹๋„์™€์˜ ์ƒํ˜ธ ํšจ๊ณผ๊ฐ€ ๊ตฌ๋งค์˜๋„์— ์œ ์˜๋ฏธํ•œ ์˜ํ–ฅ์„ ๋ฏธ์ณค๋‹ค. ๋ณธ ์—ฐ๊ตฌ๋ฅผ ํ†ตํ•ด ๋„์ถœํ•œ ์‹œ์‚ฌ์  ๋ฐ ํ–ฅํ›„ ์—ฐ๊ตฌ๋ฅผ ์œ„ํ•œ ์ œ์–ธ๋“ค์„ ๊ฐ ์—ฐ๊ตฌ์˜ ๋งˆ์ง€๋ง‰ ์žฅ์— ์ˆ˜๋กํ•˜์˜€๋‹ค.I.

[์˜๋ฌธ] Nasal polyp has been known to be one of useful target organs for studying allergic inflammation. However, there have been few reports dealing with specific antibody response in nasal polyp tissues which compare atopic and non-atopic subjects. This study aimed to confirm the local production of total and specific IgE antibodies and the presence of specific IgG in the nasal polyp tissue. We measured total and house dust mite(Dermatophagoides pteronyssinus: DP)-specific IgE and IgG antibodies using enzyme-linked immunosorbent assay(ELISA) in the supernatant of nasal polyp homogenate from 72 subjects undergoing nasal polypectomy. The pattern and extent of inflammatory cells were observed under the immunohistochemical method using monoclonal antibodies to NE(neutrophil elastase), EG2(eosinophil granule), AAI(mast cell tryptase), and CD3(pan T-lymphocyte). The subjects were divided into three groups according to skin reactivity to DP: 20 strong atopic subjects to group โ… (mean wheal diameter>3 mm), 19 weakly atopic subjects to group โ…ก(mean wheal diameter 1-3mm) and 33 negative skin responders to group โ…ข. Eosinophil was predominant cell in the nasal polyp tissue. There was no significant differences in the number of AA1 +, EG2+, NE+, CD3+ cells between atopic and non-atopic groups(p>0.05, respectively). Group โ…  showed significantly higher levels of total and DP-specific IgE levels in the nasal polyp tissue than group โ…ก and group โ…ข subjects. Significant difference was noted in total and specific IgE level between group โ…ก and group โ…ข. There was a significant correlation between total IgE and DP-specific IgE level in the nasal polyp homogenate [r=0.75 p=0.00]. The ratio of polyp total IgE/albumin was greater than 1.0 in most subjects of three groups(79 - 97%). There was no significant correlations between specific IgE level and the number of AA1+, EG2+, CD3+ and NE+ cells. Specific IgG antibody was found in three groups and there was no significant difference in DP-specific IgG antibody level among three groups. These results suggest that local production of total and specific IgE antibodies were confirmed within the nasal polyp tissue from some weakly atopic and non-atopic subjects as well as strong atopic group. Further studies will be needed to investigate the role of specific IgG in nasal polyp inflammation.restrictio

[์˜๋ฌธ]This study was designed to estabilish normal range of AFP levels in maternal and amniotic flued at 9 to 41 weeks of gestation. AFP levels during pregnancy signify the possible index of confirming congenital anomaly of fetus including neural tube defect such as anencephaly, spina bifida, meningomyelocele. Total 197 cases were screened for serum AFP levels and 18 cases for amniotic fluid AFP levels from normal pregnant women between 9 and 41 weeks of gestation at the Department of Obstetrics and Gynecology, Yonsei University College of medicine from January 1st, 1985 to October 30th, 1985. Enzyme immunoassay was used to determine the titer of AFP in maternal serum and amniotic fluid. 1. The following results were obtained: Normal range of maternal serum AFP from 9 to 34 weeks of gestation and median range of amniotic fluid AFP from 16to 41 weeks of gestation were obtained. 2. Maternal sereum levels of AFP were gradually increased from 12 weeks of gestation reaching to maximum at 29 weeks of gestation and AFP levels in amniotic fluid reached to peak value at 17 weeks decreasing there after. 3. The concentration in amniotic fluid AFP was decreased as the pregnancy advances from 17 weeks to 41 weeks and the concentration in maternal seurm AFP was increased as the pregnancy advances from 12 weeks to 34 weeks. 4.Serum AFP levels of mothers who delivered female babies were significantly higher than those of mothers who de-livered male babies. 5. One case of congenital anomaly, teratoma of tongue, was accompanied by high levels of seurm AFP suggesting that sereening of maternal AFP level could be useful to detect congenital anomaly of fetus.restrictio

[์˜๋ฌธ] Virulence or pathogenicity of free-living amoebae was been judged mainly in-vivo. However, experiment in-vitro has also been tried in recent years to avoid the complexity of animal experiment and to save time and expenses. Visvesvara and Balamuth (1975) reported that the tests of cytopathic effect in tissue culture might be useful way to determine the virulence of the amoebae and Josephson et al. (1977) found that pathogenic Naegleria strains were agglutinated by phytoaglutinin. The present study is to visualize the relationship between the pathogenicity of free-living amoebae in considering with the agglutinabilily of respective strain. The free-living amoebae teat in the stuffy were: Naegleria fowleri, Acanthamoeba culbertsoni, A. hatchotti, A.lenticulate, A. royreba, A. triangularis and Abanthamoeba sp. (YM-4). For reference, Entamoeba histolyica strains isolated from amoebic hepatic abscess cases were also teated. Free-living amoebae were cultured in the non-nutrient agar plate (Kasprzak and Mazur, 1972) and CGV or CGVS medium(Willaert and LeRay, 1973). For the pathogenicity test white mice weighing 15-20 gm were used. Free-living amoebae trophozoites were inoculated into the nasal cavity of mouse under the anesthesia by intraperitoneal injection of secobarbital, and pathologic behabiour and brain tissue pathology were observed during the experimentation. Free-living amoebae trophozoites were washed three times with 0.9% (w/v) NaCl containing 0.01 M phosphate buffer (PH 7.0-7.2) and then suspended carefully. One drop of the cell suspension wart mixed with came amount of concanavalin A of various concentrations on the Boerner slide and incubated at 36โ„ƒ for given period of time. Microscopic observation to determine the occurrence of agglutination was done. And agglutination was also measured using spectrophotometer by transmittance of free-living amoebae suspension in the presence of concanavalin A. Cell suspension in 0.9% (w/v) NaCl containing 0.01 M phosphate buffer (pH 7.0-7.2) was added to the same volume of concanavalin A of various concentration establishing a final volume of 2ml, and then agitated well. Experimental reading was done with spectrephotometer (Bausch and Lomb) at 660 nm at 30โ„ƒ. Any increase in transmittance observed in each experimental readings was substracted from the zero time reading. Percent agglutination was calculated from the expression (Y-X/X)ร—100, where X is the transmittance at zero time and Y is the transmittance at any given incubation time. Acanthamoeba sp. YM-4 tropzoites, that is confirmed to be nonpathogenic to the mouse, agglutinated easily by more than 25 ฮผg/ml of concanavalin A. Pathogenic Acanthamoeba culbertsoni, which was subcultures for a long time was agglutinated by 25ฮผg/ml of concanavalin A. Pathogenic Acanthamoeba tenticulata was agglutinated by 25 ฮผg/ml of concanavalin A, nonpathogenic Acanthamoeba royreba by 100 ฮผg/ml, nonpathogenic Acanthamoeba hatchotti 25ฮผg/ml, Acunthamoeba triangularis 100 ฮผg/ml. But no agglutination was obtained with Naegleria fowleri and Entamoeba histolytica at any of the concanavalin A concentrations tested. In agglutination, the beat result was achieved using a cell density of 157ร—10**4 /ml of Acanthamoeba sp., YM-4. Agglutination reached to the highest rate after 45-60 minutes at the concanavalin A concentration of 100ฮผg/ml. The overall results suggest that concanavalin A-induced agglutination is related with the pathogeicity in the Naegleria sp. but net in the Acanthamoeba sp.restrictio

[์˜๋ฌธ] Down's syndrome is a major cause of mental retardation and the incidence of Down's syndrome is 1-2 per 1000 live births. The diagnosis of Down's syndrome during the pregnancy includes the karyotype with the chori-onic villus sampling and amniocentesis, but the result requires 3 weeks. Therefore an accurate and less time consuming screening method is highly important. There has never been a report on molecular analysis of Down's syndrome in Korea, so it is required to develop a rapid and new diagnostic method for the screening of Down's syndrome. This study was designed to establish a rapid and accurate method to detect trisomy. DNAs were prepared from the bloods of 15 cases Down's syndrome and 10 cases of normal patient. To determine the trisomy by an effective and accurate method, small tandem repeat analysis of D2lSII and semiquantitative analysis of S-lOOB gene and semiquantitative analysis of APP gene in Down's syndrome with PCR were performed. 1. Small tandem repeat analysis of D21SII showed as follows: Normal subjects revealed 3 cases of sin91e band(homozygous), 7 cases of equivalent 2 bands(diplozygous). Down's syndrome revealed 9 cases of unequivalent 2 bands, and 6 cases of equivalent 3 bands. There was a significant difference between normal controls and patients with Down's syndrome. 2. Semiquantitative analysis of APP gene skewed no significant difference between normal controls and Patients with Down's syndrome. 3. Semiquantitative analysis of S100B gene showed difference between normal controls and patients with Down's syndrome. However, the accuracy was slightly lower compared with the STR analysis of D21SII. From these results, small tandem repeat analysis of D21SII may be effectively used for the diagnosis of Down's syndrome. Semiquantitative analysis of S100B could be used to differentiate normal chromosome from trisomy. These methods eliminate the disadvantages of high cost and time consuming procedures such as tissue culture or Southern blotting. Diagnosis of Down's syndrome using quantitative polymerase chain reaction and small tandem repent polymorphism with D21sl 1 will be a useful and accurate method.restrictio
